Thanks a lot for your help, Dieter, Greg, and Andy!

Dieter, you were absolutely right about the broken instances. All I had to
do was delete ZSQLMethods from my Products folder and restart Zope.
Everything was all right after that.

Andy and Greg, so far I did not have any problems using mysqlpython 1.2.0
with ZMySQLDA 2.0.8. But since Andy is the expert I now installed 2.0.9b3
and am happy with it.

:-) Cheers and thanks again,

Ragnar

Rob,

I was recently working on a similar problem.
You will need to use the xmlhttprequest function in Javascript do all the 
work. And its quite easy once you get the hang of it. Heres a good tutorial 
to get started:
http://developer.apple.com/internet/webcontent/xmlhttpreq.html

For your problem, if your required server result is a simple list, let a 
zope script generate a tab-delimited list and you can retrive it using the 
request.responseText (see the xmlhttprequest) and skip working with the 
XMLDOM, which can by quite annoying.

Thanks to all the responders. It gave me some ideas, but alas no luck.

To clarify, I am not trying to do everything in one request. Request
one generates the page, a user event (selecting an option from a form)
fires another request via javascript.

like:
<script tal:content="python:'function getFormats() {
var widget = document.getElementById('orgs');
var chosen_org = widget.options[widget.selectedIndex].value;
var formats = %s;
// build selection 2 options from formats
' % here.getDataFormats(chosen_org)" />

And then a user event (onChange) calls getFormats.

Even with generating the script with a Python script or DTML, the
problem remains (for me at least) to get a value from the DOM passed as
an argument to a Python script that queries my database. If my Python
script didn't take an argument, I'd have no problem. I could do this
and use javascript to build the select options from the appropriate
values. But I'd like to cut down on what the browser has to handle.
What the user chooses in the first selection can reduce what they get
to choose in selection two from 3000 choices to hundreds. I'd prefer to
have the backend reduce the result set rather than having the browser
do the work.

I thought about AJAX (no experience), but given time constraints, looks
like I'll have to load everything on the page and go from there.

hi all!

i think there should be no functional difference in the two code snippets
below, but is there any difference in performance?
(i know, the "except AttributeError" could possibly mask an AttributeError
in the called function...)

1.:
hook = getattr(o, '_before_transaction_commit', None)
if hook: hook()

2.:
try: o._before_transaction_commit()
except AttributeError: pass

Don't know, and don't care; these are (at the Python level)
functionally different.

Exactly.  Shouldn't be a real issue in a released version, but better
safe than sorry.

Better yet:

 hook = getattr(o, '_before_transaction_commit', None)
 if hook is not None: hook()

Define "locale" in your Zope configuration file.

Then "locale" should be imported when Zope is initialized.

Unfortunately, it is as crucial that you include the traceback

You are aware that you will not get a list (but a tree) when you
look down from some starting point?

When you are ready to look up (in the hierarchy), then

     obj.aq_inner.aq_parent

is the hierarchy parent of "obj".

I suspect he meant a list in the HTML - he is using <ul> and <li> tags 
there.

But Dieter, can you elaborate on what you mean?  Isn't the result from 
objectValues() a tuple [which would be a "list" in most languages].

Do you simply mean that the Folder objects may contain File, Document, 
Image or Folder objects, recursively?  If not I'm not sure I follow.

Thanks,
N

John, I'm not sure what you mean either -- but if my guess *is* right, 
try changing the two occurrances of "context" to "context.groups"

I think it should *definitely* be written in Python, although a "Script 
(Python)" should suffice.  Add a "Script (Python)" with an ID of 
"make_list" and a parameter list of "items"   The following is untested, 
but should work, I think.     Beware of any special text in the strings 
(&,<,>,etc).
 
######
text = "<ul>\n"
for item in items:
   if isinstance( item, ( list, tuple )):
       text += context.make_list( item )
   else:
      text += "<li>" + str(item) + "</li>\n"
return text + "</ul>"

Message-ID: <20050701225107.58132.qmail@web25706.mail.ukl.yahoo.com>

Hello again,

So, following the recommendations from the board I
have settled on "route 3" - developing a Python
Product, using Zope 3. I've been refering a lot to the
Zope 3 Book (particularly chapter 13 onwards) and have
progressed somewhat.

I've created a "PropertyFolder" class, which can hold
Property obects, and following the example in the book
I've been able to make it hold *only* Property
objects.

My "Property" class is proving a little more
difficult, however. When I've tried to make it along
the same lines as the "message" class in the book, I
run into difficulties - it seems to be some sort of
problem with inheriting from multiple classes /
interfaces. My workaround has been that I can include
my __setitem__.precondition within the main IProperty
interface, and make that subclass from IContainer
instead of Interface. This works for me, because I'm
not going to want Property objects to contain other
Property objects, but I really haven't been able to
track down why it should work for the message board,
but not for my classes / interfaces. The errors I was
getting before my work around seemed to be indicating
that it wasn't a container, although I was subclassing
BTreeContainer, and implementing three interfaces (one
and Interface, one and IContained, and one
IContainer).  Mostly this presented itself as Zope
complaining about using __len__ on the object. (As I
say, I have worked around this, and mention it mostly
in case it sheds any light on the issue below...)

My current problem, however, is proving harder to work
around. I want my Property objects to be able to
contain Images, and sets of attributes. (A typical set
of attributes would describe what is in the kitchen).
I have created interfaces IAttribSet(Interface),
IAttribSetContainer(IContainer) and
IAttribSetKitchen(IAttribSet); and classes AttribSet
(implements IAttribSet and IAttribSetContained) and
AttribSetKitchen (implements IAttribSetKitchen). I am
using IAttribSetContained to create a __parent__
ContainerTypesConstraint. I have wired up the kitchen
attrib set in .zcml files.

When I 'turn off' implementing IAttribSetContained, my
kitchen attrib set is working fine, in that I can add
it anywhere, and edit it. However, when I try to add a
condition saying where it can go (i.e. I only want it
to be within Property objects) it correctly only
appears as an Add-menu item within Property objects,
but on adding it, I get an error, saying
"AttribSetKitchen instance has no attribute
'__parent__'". My Property and PropertyFolder objects
are implemented as BTreeContainers.

I'm really quite stumped by this, so I would
appreciate any guidance that could be provided on
tracking down the source of the errors.

Thanks,
Jim

The code above is not valid HTML[1]. This is one way how to do it:

<ul tal:define="nodes python:['a', 'b', ['c', ['d', 'e']]]">
   <li metal:define-macro="item"
       tal:repeat="node nodes">
     <span tal:define="global is_list python:same_type([], node);
                       content python:is_list and 'list:' or node"
           tal:replace="content"/>
     <ul tal:condition="is_list"
         tal:define="nodes node">
       <li metal:use-macro="template/macros/item"/>
     </ul>
   </li>
</ul>

>> I guess the template could call itself repeatedly.  Which means the

To embed it in another template simply call it:

<ul tal:replace="structure here/list"/>

(Or define a macro and use that).

Even better if the logic is in a script that renders the template, I think.

I've made recursive macros before. It's not so different from other 
recursion techniques. Here's one to render a site tree::

  <html>
    <head>
      <title tal:content="template/title">The title</title>
    </head>
    <body>
      Site structure:

    <tal:contain define="location nocall:here">
     <div metal:use-macro="template/macros/list" />
    </tal:contain>

    </body>
  </html>

  <tal:hidemacro replace="nothing">
  <metal:recurse define-macro="list">
    <ul>
      <li tal:repeat="elt location/objectValues">
        <span tal:content="elt/getId">objectId</span>
        <metal:block tal:condition="elt/isPrincipiaFolderish"
                     tal:define="location nocall:elt">
            <div metal:use-macro="template/macros/list" />
        </metal:recurse>
      </li>
    </ul>
  </metal:recurse>
  </tal:hidemacro>

It will go from 'context', of course, unless you were to change the 
definition of 'location' in the page.

You can imagine how this would work with a nested list: you just have to 
have ways of checking containership and getting contents.

It was/is set in the etc/zope.conf:

  locale hu_HU.UTF-8

And exactly this same locale works in C programs, so it is installed on
the OS.

Hi,

I hope it's not considered "bad form" to answer ones
own questions on this board, but I think I've got it
sussed.

Reading through the ZWiki source from
http://svn.zope.org I noticed the following line in
the implementations:

from zope.app.container.contained import Contained 

I added this to mine, and it has cleared up the error
a treat.

Thanks,
Jim

PS - In scrabling around the net trying to solve this
I read somewhere (I think it was a Python Tutorial)
the following advice:

"Use the source" (Luke...)

I can strongly recommend to any other newbies looking
for examples to take a look at to try out ZWiki - it's
got a reasonably small number of interfaces and
classes, so you can get your head around it, and it
covers useful things like containment.

I have problems with the terminology which Zope uses, but I think you 
understand what I meant.

Well that would be useful if I understood what you meant. Is there a 
suggested explanation anywhere with some sample code which uses this 
construct?

This construct returns the *hierarchy* parent vs. the *acquisiton* parent.
See Zope Dev Guide for details on Acquistion.

Hi there,
can anybody tell me what the transitional email in MaildropHost is?

I read that it is aware of transitions. what transitions?

I looked and saw numerous broken links but no sample code.

It's only sample code which actually creates any meaning to many of these 
explanations.

yes in deed.
what is a transaction in the context of MaildropHost.
How does it affekt an email?

The "transaction" here is the normal Zope / ZODB transaction, which
ensures that writes to the ZODB (and any transaction-aware RDBMS) are
aborted if the request raises an exception.  The "transaction-aware"
feature of MaildropHost is that it holds off sending the e-mail until
the transaction is committed, which ensures that you don't get a
premature e-mail (in the case that the transaction is aborted), or a
repeated one (if the request is retried due to ConflictError).

Well, you should know that Zope retries to execute a method up to three 
times in case of a ConflictError. If you send out mail using MailHost 
within one transaction this could cause the sending of up to three mails in 
case of a ConflictError. MaildropHost solves this issues.

Subject: [Zope] Apache 2 + Zope can't gzip HTTP response body?
Message-ID: <913033969.20050702205602@freemail.hu>

Can I use HTTP "Content-Encoding: gzip" for Zope if I use Apache 2? (And
should I use gzip content-encoding?)

The mod_gzip doesn't work with Apache 2, but instead it has mod_deflate.
But mod_deflate can't chose which responses to gzip based on the
MIME-type for responses that are coming through
ProxyPass/ProxyPassReverse. And with Zope I can't rely on extensions
(like .html), just on the MIME-type. Do I think these well?

Somebody have solved this (gzip-ing the response bodies)?

Hi all
I would like to create a product with a function called struct.xml

I would like if I could access it via FTP because I would like editor 
integration

I open the file via FTP and I save it via FTP and PUT_factory mechamism

Can I make struct.xml accesible via a FTP file?

Thanks!!!

Subject: [Zope] [ANN] TextIndexNG 3.0.4 released
Message-ID: <27F610E335745ADD9B0808B7@localhost>


I am pleased to announce the release of TextIndexNG V 3.0.4.

TextIndexNG V 3 is a complete new implementation based on Zope 3 
technologies and can be used both in Zope 2.8 or 2.7 (with Five) or in
Zope 3.

What's new?

 - multi-field indexing and query support

 - multi-lingual support

 - configurable converters (through ZCML)

 - new indexing API (allowing you to hook your custom content types with 
TextIndexNG
   through Zope 3 adapters).


Changes since V 3.0.2:

   - added stemming support for eleven languages

   - fixed several bugs in the multi-field query support

   - keyForDocument() no longer raises an exception causing a crash of the 
ZCatalog ZMI screen for
     documents not indexed by a TextIndexNG3 instance

   - now licensed under the Zope Public License V 2.1 (ZPL) - was formerly 
GPL


Requirements:

  - Zope 2.8 or Zope 2.7 (+ Five) or Zope 3 (Zope 3 has nothing like 
catalogs yet)

  TextIndexNG V3 will *not* run with bare Zope 2.7 installations without 
Five
  (and this will not be changed in the future).

Download:

  http://sf.net/projects/textindexng


For installation and documentation issues refer to doc/README.txt from the 
archive.
It's basically the same procedure as with former versions except you *need* 
to
recompile the extension modules. Windows binaries of the required extension 
modules
are currently not available (any volunteers?).

TextIndexNG V 3 is published under the ZPL.

Sure you can. Any object/method that is in Zope becomes available via FTP. 
Some example code::

class MyProduct(Folder):
    def struct_xml(self):
          return "<tag>1</tag>"
    def PUT(self, REQUEST, RESPONSE):
        if not REQUEST.get('BODY'):
            get_transaction.abort()
            RESPONSE.setStatus(405)
        else:
            body = REQUEST.get('BODY')
            self._save_struct_body(body)
            RESPONSE.setStatus(204)
        return RESPONSE


setattr(MyProduct, 'struct.xml', MyProduct.struct_xml)

Hi!
does this work on a folder?

The struct.xml function is on a folder object and I would like 
struct.xml as an object contained by the folder one

Thanks!

Subject: [Zope] blacklisting referers and/or specific hosts
Message-ID: <2649.82.45.210.74.1120417542.squirrel@mail.zoper.com>

Hi,

I have a zope site up and running which has recently had a *lots* of hits
from a client (or clients) that show referers pointing at various
gambling, meds, and loan sites.  Requests only come in for the main page,
not for the associated images, css, etc that should go with it.

The consequence is that my server is working harder to service a client
that isn't interested in what it has to say, and my Z2.log is now far less
useful to me as all these bogus requests drown out most of the useful
information.

So, I'm wondering if there's a way to blacklist those clients that I don't
like based on host/ip and/or on referer.

If I hook into the traversal process in the same way as the virtual host
monster objects do, could I check the request against my blacklist and
then do a REQUEST.close()?  Would that still appear in my logs?  Does that
even make sense?  Is there a HTTP response code that I could return to
these clients that would stop them being interested in my server?

Any ideas much appreciated.

Tim

If there is a set of distinguishable IPs/hosts, then use a tool that  
was *made* for that purpose such as a firewalling/filtering tool  
(IPTables, IPChains, fw, etc) and not Zope.

Sure it does. Did you understand any of my code? I subclassed it on
the folder class.

This is completely outside the zope management interface. Perhaps it
is possible to override the PUT() function inside Zope but I doubt it.
Look into writing your own python product.

Subject: [Zope] ZPT with Zope 3 queries - repeat over contained items;
	accessing adapters
Message-ID: <20050703203024.87169.qmail@web25702.mail.ukl.yahoo.com>

Hello,

I'm building an application in Zope 3. I have a
container object called a PropertyFolder, which holds
Property objects.

* Repeating over contained items.

I'm trying to create a view which displays a list of
all the Property objects in a property folder. I've
tried doing this as described in the ZPT chapter of
the Zope Book (2.6 edition), using a tal:repeat
statement, but I can't seem to get it working. Has
something changed in Zope 3? I've tried looking in the
Zope 3 book, but none of the references to tal:repeat
in there seem to be used for this type of thing.

* Accessing adapters in ZPT

I've created an adapter that provides a method called
getStars that can be used on Property objects. Can I
access this directly from my ZPT, as I can any other
attribute of a property object? At the moment I've got
it implemented via a Python view class, so my ZPT
accesses it like:

<div class="field" tal:content="view/stars" />

but other attributes can be accessed like:

<div class="field" tal:content="context/description"
/>

so I guess I want to be able to do:

<div class="field" tal:content="context/getStars" />

and negate the need for the Python View Class, which
only says:

    def stars(self):
        """Get the stars for the property"""
        rate = IPropertyRate(self.context)
        stars = rate.getStars()
        return stars

Thanks in advance for any tips.

Thanks,
Jim

Zope can do "gzip" compression by itself.

You can activate it via

    "RESPONSE.enableHTTPCompression(REQUEST)"

This activates "gzip" compression for precisely this response.

Maybe, the import order has changed and "sequence" is now imported
before reading the config file (although that would be very astonishing).

Anyway, the "if modules.has_key('locale')" seems stupid.
Remove it and file a bug report.

The poster described his aim *very* vaguely -- by an
example that can be interpreted in different ways.

I concentrated on the "PARENTS[...]" part of the example.
It could mean that the poster is interested in part of
a path but it unhappy with the point where the path starts.

Now, if I choose a point and look upward, I see a single path,
however, when I look downward, I usually see more than one.

Is the explanation above enough to explain what I meant?

I know now that I did not understand what you meant...

To get the subfolders of a folder, you can use its "tpValues" method.

As as you like code: it looks like "folder.tpValues()".

We are on completely different wavelengths:

  I do not understand your questions because they are wrapped
  in (irrelevant) examples.

  An you do not understand my answer

   * first, because it is not an answer to your question as
     I did not correctly understood this

   * second, because I use abstract terms and hate examples larger
     than necessary.


Had you simply asked: how can I get the list of a folder's
subfolders, my answer would have been "folder.tpValues()"
and both of us could have been happy....

Thanks! Just on more thing... According to
http://sourceforge.net/mailarchive/forum.php?thread_id=7393296&forum_id=12354
the gzip compression was enabled by default in Plone 2.0.x (only from
2.0.4 I guess), but will be disabled in 2.1. If it is true, why? Is it
not recommenced after all? (Actually I try to gzip only because my
predecessor did...)

Hi Tim.  I think what Jens has to say is the best solution. I have also 
made my own thing with zope as well since I don't always have control 
of the firewall.  I worked out a simple ip and country-ip solution. I 
made a simple interface for adding ips to a black list or selecting 
countries to add to black list. The logic makes a final connection to 
my main site template so ips in black list or ip turning out to be from 
a black listed country get nothing but an empty page (including an 
empty page header) while those that I want to view my site will get 
rendered pages.  I use a county-ip database that gets updated once per 
week (about 50,000 records) representing ranges from all countries.

I think is is becoming clearer that many of the threats on the Net come 
not only come from specific ips but specific countries as well.
To me, blacklisting and filtering those who see your site based on ip 
or ip ranges is just a little more risk management and less expense on 
bandwidth for those you don't want to invite in.  As Yens has pointed 
out, it would be best to stop this at the firewall if you can.  This 
may not be possible based on how you are serving your sites as in a 
hosted arrangement.  My feeling is that if someone is visiting (by 
looking at your site or sending a robot) it may deter some if they are 
seeing or collecting nothing. But it would do little for those sniffing 
for the server you are running and testing purely to see that your 
alive for some future exploit attempt.

David

Yes, this is the problem I have.  I'm hosted on zettai, so am a little
limited in the options available to me (I believe).  Zettai have said they
will have a solution in place within 2-3 months, but I'd really like to
sort something out in the meantime.

Blimey, 50,000 records sounds pretty heavy (for my purposes)!  As far as I
can tell, there are two or three IP addresses producing all of these pesky
requests.  Do you have code that you can share?

Message-ID: <pan.2005.07.04.15.29.08.249772@yahoo.com>

I am trying to use 'zopectl debug' for the first time with zope-2.8.0,
local ZEO setup. It worked fine with zope-2.7.x and earlier. I am now
getting a file locking error on Data.fs.lock, which stops the debug
initialization at that point. The problem occurs whether I run zopectl as
root or as the effective user ('zope')

Can anyone familiar with local ZEO debugging on linux spot what might be
the cause of the file locking error? Thanks.

Subject: [Zope] ZPT with Zope 3 queries - repeat over contained items

Message-ID: <20050704200958.4522.qmail@web25702.mail.ukl.yahoo.com>

Hello,

Re-reading this, I realised I'd not provided much
information on the "repeat" problem, so I'm filling in
some gaps.

This works as I would expect:

<table border="1" width="80%">
  <tr>
    <th>Number</th>
  </tr>
  <tr tal:repeat="item context/items">
    <td tal:content="repeat/item/number">#</td>
  </tr>
</table>

i.e., if it is repeating over a property folder with
four objects in it, it produces a table headed
"Number" and with 4 further rows with numbers 1, 2, 3,
and 4 in.

However, as soon as I add any meat to it, e.g.:

<table border="1" width="80%">
  <tr>
    <th>Number</th>
    <th>Name</th>
  </tr>
  <tr tal:repeat="item context/items">
    <td tal:content="repeat/item/number">#</td>
    <td tal:content="item/Name">Name</td>
  </tr>
</table>

I get an error which shows up on the error log as:

"TypeError: tuple indices must be integers"

I have tried the second <td> element as all sorts:

    <td tal:content="item/name">Name</td>

and:

    <td tal:content="item/title">Name</td>

and:

    <td tal:content="item/getId">Name</td>

and:

    <td tal:content="item/street">Name</td>
(all of the objects in the PropertyFolder have a
"street" attribute)

These all give the same error. Since my simple test
case works, it seems like I'm setting the loop up
correctly, but am asking for the data in the wrong way
later on. getId and title certainly look from the Zope
2.6 book like they should work, and I tried the rest
as "guesses". Where should I be looking to find the
correct information on how to do this in Zope 3?

Thanks,
Jim

Subject: [Zope] Pass objects from template to template via HTML forms.
Message-ID: <2fdabf1905070413534e0edd76@mail.gmail.com>

Is there some way to pass an object from template A to template B via
HTML forms?

A
<form name="a" action="b" method="post">
<input type="hidden" name="obj" tal:attributes="value here" />
<input type="submit" value="Press" />
</form>

B
<b tal:content="structure here/REQUEST"></b>

Template B prints:
form
obj	'<OrderedFolder instance at 42d9aec0>'

I need the object itself, not the string representing the object!

I already searched the archive and found a similar request
(http://mail.zope.org/pipermail/zope/2003-November/143487.html), but I
have not solved the problem.

Can you suggest something to try? Thanks

You do get the object itself when you access REQEUST['obj'], only in
HTML you get something like the above, as that's what the string
represenation of obj is.

Why then, if template b is:

(or <b tal:define="obj python:here.REQUEST.form['obj'].getId()"></b>)

zope gives this error?

I get a little fuzzy on when the changeover from user root to user zope
happens, but this is the confusing point, and why I originally excerpted
the directory listing: doesn't (effective) user zope already have
read-write on the Data.fs.lock file?

Should I add user root to group zope, or would that defeat the security
purpose of the effective-user? Or can you recommend the correct chmod
setting for this setup, I don't want to 755 the thing into wide-open
access without knowing what I'm doing. Thanks.

If you dont think it's file permissions, one thing this could also be...
is your data.fs on an NFS partition?  flock doesn't work well on NFS.

This is a local ReiserFS partition. The zope and zeo are on the local
machine, communicating over port 9999.

I just checked, and it is not the 'zopectl debug' that fails, it is the
second connection to the running zeo; if you run zopectl debug first, that
starts, and the normal zope service will fail instead.

I just did a chmod 666 Data.fs.lock
-rw-rw-rw-  1 zope zope       6 Jul  4 22:15 Data.fs.lock

And to my surprise, that doesn't change the second zeo connection problem,
either.

Because REQUEST.form['obj'] is already a string representation of then 
object, not object itself, hence it has not method getId()
Try looking into copy/cut/paste machinery, it seems to be what you're

This is a thing I absolutely want to avoid. I simply need to pass an
object directly from one template to another, without intermediate
steps (like, copying or creating the object with some manage_*method
from a template, read the created object from the other template and
then remove the object itself because unuseful..).

In python it is so immediate: I pass objects between functions via
parameters; in zope the most natural way to "simulate" parameters
passing from one zpt and another is storing them inside the request
object, and thus, using html forms. But for some reasons that I'm
missing, it doesn't work!

passing objects from one template to another via the REQUEST variable only
works while you're in ONE request. otherwise you'll get a string
representation as you mentioned.

try using the session mechanism instead:

You cannot simply pass a ZOPE object in a form like that.
You can handle fairly complex structures (lists and dictionaries
with int, float, string in them) but whole objects would
need to be pickled and then open a huge security hole
(Whatever is in the client can and will be faked)

So best option I see is to not pass the object but rather
pass the reference to the object. You can resolve
it via restrictedTraverse('/path/from/form')

Btw. avoid much code in the Template. Its a maintenance
headache. You can do it esily in a python script and 
call this from template.

I think I can't apply your solution. restrictedTraverse asks for a
path, and then it supposes that the object is stored inside ZODB. This
is not my case. Let me provide a minimanl explaination about how my
application is structured.

1. A user can uploads a zipped file via HTML form in "upload_zip" ZPT.
The action of the form points to check_zip, an External Method that
checks for validity of each file inside the archive.

2. check_zip returns to upload_zip a tuple containing two elements:
True or False (based on the correctness of archive) and the object
itself, via self parameter.

3. after the external method has been called, upload_zip shows other 2
forms that the user will use to abort operation or to continue the
process. The form to continue will pass the object to another external
method in order to compute the result. This is the step where I
encounter the problem, I can't pass object.

This should explain why I haven't the object stored inside ZODB.

Probably the solution would be to store the uploaded object inside a
temporary area of ZODB and then I'll be able to do all the tasks I
need.

Any further consideration/hints?

Thanks

Yes, once found the way to follow, spread the code between dedicated
objects will be pure amusement ;-)

You would be better off storing the file on the filesystem, and pass the
filename around. You'd have to do some sanity checking on the filename before
any manipulation obviously.

Well yes, thats very easy. Just store your (compressed or not)
HTML data (since its a string after all and not such a complex
object) in a hidden form field (base64 encoded for example) ->

filedata=htmldata.encode("base64")

and the other parts of your form as you wish. Maybe you prepare
the data in a script and call the ZPT from it:

return context.yourZPT(filedata=filedata,somestatus=whatever)

and use: <input type="hidden" tal:attributes="value options/filedata"
type="text" /> in your ZPT.

When the request returns, use: htmldata=filedata.decode("base64")

alternatively you can just store the data in REQUEST.SESSION
to keep it on server (but watch the memory usage)

Sure, you don't need to use copy/paste mechanism, just look on
the implementation. AFAIR it just pickles list of absolute_url()'s and
stores base64-encoded result into cookies.

Running zopectl debug runs your normal instance with additional debug
breakpoints and pdb started. So in the same way that you cannot start
the same instance twice, you cannot start your instance and a zopectl
debug at the same time.

Umh, that's incorrect. zopectl debug has nothing to do with debug  
breakpoints or pdb. And you can run it right alongside your running  
Zope instance. All it does is present you with a Python prompt where  
the root object is bound to "app", nothing more and nothing less.

One correction: If you use ZEO you can run it alongside the running  
instance. Otherwise, since it would want exclusive access to the  
database, you could not. One of the reasons why ZEO is recommended  
even in single server setups.

Likely, 'context' is a dict, or a workalike, whose 'items' method
returns a sequence of tuples.  Therefore, during the tal:repeat, 'item'
is a tuple, (key, value).

Try using 'values' instead of 'items'.

No can do I'm afraid.

The objects you deal with live only in the Zope server. When you send a
response back to a user, this is just HTML, made of strings. Based on
this, the user's browser sends back a new HTTP request, again made up of
strings.

When this new request arrives, Zope has forgotten the previous
response, apart from perhaps something in a user's session or in the ZODB
somewhere.

So, if you wish to keep track of an object during a sequence of requests
with the user, you must make arrangements to keep the object somewhere in
Zope, and to find it as each request comes in.

Common ways to cope in this situation include:

- Make do without an object at all; run everything with just strings until
you come to the end of the process and are ready to commit to the ZODB.

- Store an object in the user's session.

- Store an object in a temporary location in the ZODB, and pass around a
path to it in your various forms.

Hope this helps.

Thanks,
Malcolm.

The only thing I can think of which matches your symptoms is this. Is it
possible you have misconfigured this new Zope 2.8 instance, and it's
trying to use direct access to the Data.fs via FileStorage, instead of
contacting zeo?

Thanks,
Malcolm.

I feel like a guy who brought the lawn mower in for repair, and they tell
you 'its got no gas in it'. That was it of course, thanks for the catch.

I normally diff-merge my zope.conf with each successive version, to pick
up any new directives, comments, etc. I guess I forgot the zodb section at
the tail end when moving from 2.7 to 2.8.

It might be helpful to have the list of mounted databases (and thus ZEO
vs. FS distinction) in the control panel summary, that seems like useful
configuration summary information.

Thanks again, and sorry to take up list traffic with a simple
configuration mistake.

You can use a utility called load_site.

You can ftp them into Zope.

You can use webdav to save them into Zope...

Hi,

I just finished upgrading our production servers to Zope 2.8.0 (from Zope
2.7.6)
Today I noticed that Zope 2.7.7 is under development... and it contains some
interesting bug fixes (the one concerning if modified since header handling
for example).

I guess that these fixes will be included in Zope 2.8.1 right ?
Any idea when 2.8.1 may be available ?

Thanks.

Pascal

All bugfixes are applied (usually) to  the most recent maintained versions 
(currently 2.7, 2.8 + SVN trunk)

Thanks a lot for the replies.
I have considered all the solutions and at the end I have decided to
store the uploaded file in a zope file object inside ZODB, passing it
between zope and external methods in order to process it, and then
remove the file from ZODB.

This is the last thing I wanted to do, but considering the traps I
encountered storing objects inside the session (Error Type: TypeError,
Error Value: can't pickle function objects), and considering also that
the file uploaded by the user could be potentially very big in size, I
have thougt that store it inside ZODB instead of a session object was
a better solution.

P.S.
I just discovered a mail that looks like mine:
http://mail.zope.org/pipermail/zope/2001-August/098793.html
Probably in 4 years a lot of people have met the same "problem", but
still there is no solution to face it in the terms expressed in my
initial post; so, finally, is it impossible to implement a such thing
or it simply has never been done?

Well err. You have got all possible solutions: create object in ZODB 
and pass references around, create object in session (which is easy, you
just store the string with the data) or send the data in the form
between client and server. (Your error you mention above indicates you
did not really create an object or used atomic datatypes)

All methods have drawbacks and advantages. Despite of having the user
select the same file again to send (which would be the 4th solution)
there is none left. This isnt genuine to zope but inherent to all 
solutions which work over HTTP.

I'd suggest to skip the 2-phase upload in favour of a one shot
with all the relevant data. E.g. "[ ] check here if you want
this and that" in the same form as the file gadget.
Especially if the files are potentially large.

Yes, I have seen that environment variable earlier... with that Apache
compress text/html *only*, but not text/css and text/javasript. OK,
compressing text/html is that mostly matters, so you are right, I don't
care and will use that. But it's funny... if it is possible to compress
text/html only, then how is this not possible with any MIME-types I
choose...

For those of you who is interested:

# AddOutputFilterByType doesn't work with
# ProxyPass/ProxyPassReverse, so:
SetEnv gzip-only-text/html 1
SetOutputFilter DEFLATE

If you notice a bug fixed in 2.7.* but not in 2.8.* then it's an
oversight by the bug fixer, or a regression. Please report it to this
list or in the collector.

Subject: [Zope] LDAPUserFolder OLD and Zope 2.5.1 migration to
	LDAPUserFolder 2.5 and Zope 2.8
Message-ID: <1120585332.7567.19.camel@localhost.localdomain>

I believe it was Jens that gave me the how-to on how to migrate an
existing Zope 2.5.1 install using LDAPUserFolder for authentication to
Zope 2.8.  Below is his response with some of my questions:

- Get the latest released LDAPUserFolder version and install it into  
your new Zope 2.8-based instance

I have done this.  

- Make a backup copy of your old ZODB

If you mean the Data.fs, then this is done also.

- Log into a 2.5.1-based instance as the emergency user (-> see doc/ 
SECURITY.txt in your 2.5.1 Zope installation about how to create one) 

I can't do this part because I was left with no info in regards to what
the credentials are as the emergency user.  I have located the access
file though.  Can I delete this file and create a new one documented in
SECURITY.txt?

- if you don't have a LDAPUserFolder in the Zope root you can skip  
that and log in as a Manager user from the root user folder

The LDAPUserFolder is in the root of the Zope instance and that is the
only place it is located.  The original acl_user folder is gone leaving
only the acl_user folder with the LDAPUserFolder code.

- Delete every single LDAPUserFolder instance you have

I can do that as long as I am guaranteed that I will be able to log in
as the emergency user and as long as when I restore the backed up
Data.fs, I will be back to where I started after the migration.

- Stop Zope
- Copy the Data.fs into your Zope 2.8-based sandbox

I am assuming you mean the cleaned up version with no instances of the
old LDAPUserFolder.

- If you had a LDAPUserFolder at the root, make sure you're set up  
for an emergency user
- Start Zope and log in either as an emergency user or a root user  
folder manager
- Recreate all LDAPUserFolder instances.

Just need one, at the root.  From there, upon logging in, if you are in
our LDAP with the right credentials, then you can manage Zope.

Message-ID: <20050705202534.25596.qmail@web25704.mail.ukl.yahoo.com>

Thanks for that info. I've tried a couple of extra
things (below) and if I'm reading the output right I
thing you're correct about "items" returning a tuple,
and "values" returning the object. When I do the
repeat like this:

<tr tal:repeat="item context/items">
  <td tal:content="item">Name</td>
</tr>

The data presented look like this:

(u'Property', <lettings.property.Property object at
0x027ABEF0>)

However when I repeat over "values" instead of "items"
like this:

<tr tal:repeat="item context/values">
  <td tal:content="item">Name</td>
</tr>

... they change to this format:

<security proxied lettings.property.Property instance
at 0x027ABEF0>

So, it looks to me like values is returning the
contained item as single item, rather than a tuple of
it...

However, I still can't drag anything out of it. Having
changed the tal:repeat to "item context/values", I
have tried item/name, item/Name, item/getName,
item/title, item/Title... All return "NotFoundError".

I've googled, but am yet to find any Zope 3 specific
documentation for ZPT - could anyone point me in the
direction of some? (Or am I just doing something wrong
that wouldn't have worked in Zope 2 either?!?)

Thanks,
Jim

Hi all!

I create a ZPT with this result:

<form name="Borrador" method="post" 
action="http://yanged:8280/Papeles/Yanged/Links/Eliminar/">
    <div id="Borrable">
        <input type="submit" value="Eliminar" name="Borrador" />
    </div>
    <div class="Links" id="Links1">
        <div id="Movible"><input type="checkbox" name="Movible:list"

    </div>
</form>

The original result has more <div class="Links"> with id="Links2", etc 
that I delete for your confort (I think this don't modify the problem)

My question is why If I push Eliminar button don't submit the form to 
the correct url (http://yanged:8280/Papeles/Yanged/Links/Eliminar)?

Thanks!

Yes, I think I understand your code but correct me if I get wrong: this 
code converts your folder in a file on the FTP server

But what I need is to see the method like a file on the folder not the 
folder itself

Did your code works like I need?

THANKS!!!

What happens instead? Look at your Z2.log to figure out what is requested.

-> 10.3.3 302 Found

The requested resource resides temporarily under a different URI. Since
the redirection might be altered on occasion, the client SHOULD continue
to use the Request-URI for future requests. This response is only
cacheable if indicated by a Cache-Control or Expires header field.

The temporary URI SHOULD be given by the Location field in the response.
Unless the request method was HEAD, the entity of the response SHOULD
contain a short hypertext note with a hyperlink to the new URI(s).

If the 302 status code is received in response to a request other than
GET or HEAD, the user agent MUST NOT automatically redirect the request
unless it can be confirmed by the user, since this might change the
conditions under which the request was issued.

      Note: RFC 1945 and RFC 2068 specify that the client is not allowed
      to change the method on the redirected request.  However, most
      existing user agent implementations treat 302 as if it were a 303
      response, performing a GET on the Location field-value regardless
      of the original request method. The status codes 303 and 307 have
      been added for servers that wish to make unambiguously clear which
      kind of reaction is expected of the client.

Your POST request seems to be transformed into a GET to another url...
Now *why* this happens, I can't tell you...

This is getting confusing. I can't have a file (seen when listing a
folder) that is clever enough to do PUT() calls on itself.
My code showed how to put a PUT() function on a folder (Folder-based).
That means that if you do a PUT request onto the Folder, (eg.
uploading a file) it get's picked up by that method.

A wild guess: Your post works, but returns a redirect to a nother
page, which returns nothing. This will look exactly like notyhing
happened at the browser side.

Yes, looking at Z2.log it seems it but If I execute the action url 
manually it works like I expect

Any idea?

Since we're not able to guess what your code is doing (well, I, at
least, am not able to...), you could perhaps post it ?

One thing that strikes me is the final slash in
"POST /Papeles/Yanged/Links/Eliminar/"

What is "Eliminar", exactly ?

Links/Eliminar is the execution path (using traverse_subpath)

But if I execute the action URL directly on the browser it works fine

hi there!

either this is a bug or i'm too stoned to see, what's going on...

i have a folder /1, 2 subfolders /1/11 and /1/22. each subfolder
has a property 'bool', which is a boolean.
there's a zcatalog instance in /1/Catalog with one index bool, indexed
attribute 'bool'. i cataloged the two subfolders of /1 there.

i have i skript /1/test with the following content:
results = context.Catalog.searchResults({'bool':1})
print results
for o in results:
  print o
  print o.getId
  print o.getId()
return printed

it prints:
[<Products.ZCatalog.Catalog.mybrains object at 0xb629798c>,
<Products.ZCatalog.Catalog.mybrains object at 0xb40d9dec>]
<Products.ZCatalog.Catalog.mybrains object at 0xb629798c>
<bound method ZCatalog.getId of <ZCatalog at /1/Catalog>>
Catalog
<Products.ZCatalog.Catalog.mybrains object at 0xb40d9dec>
<bound method ZCatalog.getId of <ZCatalog at /1/Catalog>>
Catalog

why in the world is o.getId a bound method of /1/Catalog?
o is a mybrains instance!!!

what am i missing?! help!

Easy. The brain object doesn't have a 'getId()' method. The Catalog has.
What you're probably after is something like this::

 for brain in context.Catalog.searchResults({'bool':1}):
      cataloged_object = brain.getObject()
      if cataloged_object is None:
          print "ZCatalog out of sync!!"
      else:
          print cataloged_object.getId()

i was dumb :)

the metadata table simply didn't have getId, so the brains object
acquires getId from the catalog.

sorry for my nubness ;P

Subject: [Zope] Zope won't give up WebDAV Lock
Message-ID: <42CB8D4C.5537.3A71CFD@localhost>

I have a regularly occuring WebDAV problem:

A file edited via ExternalEditor gets a WebDAV lock.  Upon closing 
(Textpad in this case) occasionally the lock is not released.

The lock is not listed in Control Panel > WebDAV Lock Manager, 
therefore cannot be released there.

Restarting Zope does not release the lock.

This is getting to be a terrible problem.  Once a lock is in place, 
the file cannot be changed, renamed, or deleted at all subsequently.

Zope is 2.7.6 Final, Fedora Core 3, Python 2.3.3

Here is the only reference that I have been able to find in the log:

2005-07-06T10:22:00 ERROR(200) SiteError http://.../PUT

Garito, if you expect anyone here to be of any help, please provide
*useful* informations. When I ask ">> What is "Eliminar", exactly ?", I
of course mean "what kind of object is it" (ie: a dtml method, a python
script, etc...).

Subject: [Zope] paypal IPN.  Debug messages missing.  Script goes zombie
Message-ID: <42CC1BAA.3070402@greengraphics.net>

Hi all!

I've been hacking together a few seperate paypal IPN connections, some 
code from basion, and some from random web scrapings...  Anyway...  
Things are working for the most part, except that this method for some 
reason dies when using urllib.urlopen(), and what is really wierd is 
that I get no error message, it just hangs.

I am running an older version of zope, but I have never seen this 
behaviour before.  The debug (-D) flag is set in start.

here is the code I am using...  As far as I can tell my syntax is 
proper...  ???

    def 
paypal_notify(self,address_street='',address_zip='',first_name='',last_name='',payer_business_name='',payer_email='',

        """ take a IPN from paypal, and update the database """
        print "Initiating paypal IPN"
        # they want us to send back their same shite (and we've just nicely
        # deblocked it from the REQUEST...)
        print "DEBUG = STARTING"
        requestform = REQUEST.form
        print requestform['quantity'] # debug test
        requestform['cmd'] = '_notify-validate'
        print "DEBUG = INSERTED NEW VALUE"
        print requestform
        print "sending request back to paypal"
        requestparams = urllib.urlencode(requestform)
        print "DEBUG = Encoded Request"
        print requestparams
        data = 
urllib.urlopen('https://www.sandbox.paypal.com/cgi-bin/webscr',  
requestform)
        print "DEBUG = urlretrieved"
        print data.read()
        print "DEBUG = DATA READ"

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

I see all my debug print commands until "encoded Request" and 
requestparams, so it is getting lost on the urlopen call.

Thanks for any help or tips.  I'll post the final IPN method when I'm done.

Cheers!

That looks like the bug you need to analyse.

There was not yet a need for me to try to understand how
WebDAV locking works. As you have the problem now, you
may need to drill down and understand it.

Surely you get an error on the urlopen() bit because it's an HTTPS protocol. 
Search the ASPN python cookbook or the google for "https python"

Next time, try to include your traceback in the email to the list.

Subject: [Zope] Pluggable Auth Service ... how is it used?
Message-ID: <200507071541.42207.richardjones@optushome.com.au>

I'd like to get session-based login going, and on the surface PAS appears to 
support that.

First up, is there any documentation?

I've set up in my PAS "acl_users" the following objects:

1. "cookies" - a Cookie Auth Helper active for Challenge
2. "session" - a Session Auth Helper active for  Extraction, Update
    Credentials and Reset Credentials
3. "users"   - a ZODB User Manager with a single user "test"
4. "roles"   - a ZODB Role Manager with the "test" user assigned to "Manager"

Then accessing a "Manager" protected method inside the folder brings up the 
login form from the Cookie Auth Helper, but submitting that form does nothing 
(it returns the empty form to me).

Switching the "cookies" object to handle Extraction, Update Credentials and 
Reset Credentials makes the login work, but I'd like to use the session.

The docs that come with the product talk about Decorators and Property Sheets 
used to extend the user properties, but I can't even find anything with 
either of those names in the UI.

The interface has "Scriptable Plugin" with a teasingly disabled "Validation" 
interface -- which I have found to mean user validation. I'd like to enforce 
valid email address capture ... when I can figure how to actually capture an 
email address, that is.

Add "Extraction" to the cookie object. Only the cookie object would  
know how to extract credentials coming back from the cookie object's  
challenge. Makes sense, doesn't it?

I have described such a setup before either here or on the PAS list  
itself, take a look at the archives. The very first challenge and  
extraction is done by the cookie auth helper, and the credentials are  
then stored by the session auth helper which is doing all extractions  
after that.

Hi Bruno
http://yanged:8280/Papeles/Yanged/Links/Eliminar is an url that if I 
call it from my browser executes some python scripts that I define in a 
XML file

Then Eliminar is a string not an object nor a method because, as I told 
you some mails ago, I has it via traverse_subpath
The real Object (travesed) is Yanged that is a mixed object with a 
ZCatalog and a folder (like plone portal_catalog)

When I ask for Yanged/Links/Eliminar I ask to the XML file to see what 
Python Scripts or Page Templates give back to me and the I execute them

But, I think its very interesting for me that an action url don't work 
if I submit the form but works if I call it directly from the browser. 
Interesant, no?

Thanks
PD: thanks for the smart-questions page, very interessant!
PD2: sorry for the personal mail I send you (2 mails) but if you push 
reply button only the personal email is used. It's necesary to push

Both have nothing in common. "debug-on" is carefully explained in 
etc/zope.conf. The same applies to the 'level' paramter.

<thinking-out-loud>
1/ Do you call it exactly the same way ? ie:
"http://yanged:8280/Papeles/Yanged/Links/Eliminar/"
or
"http://yanged:8280/Papeles/Yanged/Links/Eliminar"

2/ When you call it 'directly from the browser', you send a GET request.
When you call it from the form, you send a POST request. This may have
something to do with your problem... Are you sure you end up calling the
same component in both cases ? Is there any component involved that act
differently depending on the HTTP method ?
</thinking-out-loud>

Sorry, nothing more... :(

Hi. I am trying to use the make_hidden_input function in ZTUtils to 
create a hidden input in a ZPT but it does not appear.

I am using this:

<form name="language_delete_form" action="actions_language_summary"   
method="post"  enctype="multipart/form-data"
	tal:define="mhi python:modules['ZTUtils'].make_hidden_input;
	     dummy python:mhi(delete_ids=results)">

results is a list of dictionaries I want to pass to the form method

Can someone point out what I doing wrong? Many thanks.

Regards,
David

This code is odd. First you should something to appear inside the scope
of a <form> tag inside a dedicated tag. And you're defining mhi and dummy 
using tal:define but you don't them anywhere neither using tal:content nor 
tal:replace.

<tal:block replace="structure python:mhi(delete_ids=results)" /> 
Seems more reasonable then just assigning it to a dummy variable,

Not that I have ever used make_hidden_input, mind you, I make <input
type="hidden" /> instead. Seems easier.

Super, that solved the problem.  I had googled and couldn't find an 
example of mhi. Only the api docs which didn't say very much about 
using it in a form. I guess it should have occurred to me to use 
structure if the output is html.  Problem was that I hadn't actually 
seen an example of the output of this function anywhere - so not quite 
sure if I had to make an input tag myself and the function just filled 
the attributes or what. Now I know.

I had a good laugh at what I had written afterwards, go figure a hidden 
field that will not appear, hmm...  what could be wrong with that - 
except maybe too much time at a computer :-)

Sorry Andreas on the small piece of zpt I provided, there is much more 
to the form but thought what I provided would illustrate what I was 
trying to do.

Many thanks.

Regards,
David

Shane (and the Zope list),
I've patched your lovely BTreeFolder2 product (version 1.0.1) so that
I can doubleclick on options in the dropdown instead of having to
click the Edit button. This is using Javascript and if Javascript is
disabled, nothing happens, it just goes back to what it was like
before.

I've attached two patch files that you can chose to include. 

PS. 
To install the patch, this works for me:
$ cd zope/Products/BTreeFolder2/
$patch -p1 < BTreeFolder2.py.patch

Hi Peter or Shane.  I have been using nested CMFBTreeFolders inside a 
CMF instance but I am not clear on difference between CMFBTreeFolder 
and BTreeFolder2. I am trying to limit the number of objects to 2000 
per folder. Either folder type can be made inside a CMF site. Should I 
be using CMFBTreeFolder or BTreeFolder2 for CMF?

David

Greetings to zope.

I have just installed zope that came with the mandriva2000le(mandrake 10.2) 
and tried the excercise in the ZopeBook.  All has been well until the 
guestbook exercise wherein a particular python script was granted manager 
rights in the proxy tab.

Upon trying out the page with the script as an anonymous user, I'm asked for a 
username and password.  According to the book, this was not suppose  to 
happen since I already gave the script manager rights. Please refer to the 
error below.

There are difference between different unixes,
Linux/MacOSX/Solaris/xBSD. But all linuxes seems to work equally well.

It's usally easiest to avoid the Zope packages that many linuxes has,
and install from source.

When doing urlopen, you will want to use timeoutsocket.py (included in
newer versions of python (or zope), found as a simple file on the web in
the ol' times of zope 2.5.1. Without this your connectiion will just
hang at the urlopen command, *as there is no timeout*.

Also look out for what others have aid in respect to https, no
expirience with that myself. 

There are some applications for Plone to use PayPal (PloneMall /
PlonePayPal), you might want to look at these for sample code too.

Sascha

I asked this because I know there where, in the past, some issues
using RH9 due to threading library, and to avoid surprises I'm
interested to know if someone use Zope on Suse (that I'll begin to use
in the near future) without problems.

Maybe you forgot to attach them or the list has removed them before

It comes with a script to manage multiple Zopes, which is very useful.
I have around 50 separate Zope/Plones running for student teaching.

The only negative that I know of comes with SuSE 9.3 Pro. Zope is
compiled with Python 2.4! All my attempts to build Zope from scratch
with Python 2.3.5 have failed on SuSE 9.3. I never had problems with
building things from scratch before though.

Why do these bastards ship Zope with an unsupported Python version... 
unbelievable! Maybe a reason *not* to use Suse.

he he. I think the equivalent of using deb packages (or alike) to
install and maintain your zope is like create and maintain a zclass
project: you get started quickly but very soon you grow out of it and
the ceiling can't be raised without breaking the roof.

Subject: [Zope] getSecurityManager() vs. AUTHENTICATED_USER
Message-ID: <bc95c280050708052474e5e9d9@mail.gmail.com>

I've learnt that it's better to use getSecurityManager instead of
REQUEST.AUTHENTICATED_USER
because it's more secure. Other than that, what is the difference. I
fear I've come a across a situation when getSecurityManager() returns
nothing where AUTHENTICATED_USER did. I'm currently trying to
reproduce the situation but it might involve odd URL usage and it's a
bore to have to restart the browser every time. Just hoping someone
could give me a quick answer because I don't understand much simply by
reading the source.

from AccessControl import getSecurityManager
class MyProduct(...):
    def Who(self):
          #return self.REQUEST.AUTHENTICATED_USER.getUserName()
          return getSecurityManager().getUser().getUserName()

Subject: [Zope] sending e-mail in external methods
Message-ID: <c01cd4fa05070806596a9c1c9e@mail.gmail.com>

Hello everybody,
I am a new zope user that has received an application to maintain and
I'm learning about zope at the same time.
One of the features of the app requires users to subscribe to receive
a newsletter.
A user is presented with a very simple form
<form method="post" tal:attributes="action
string:${here/absolute_url}/Register" metal:fill-slot="content">
Name: <input name="name" type="text" tal:attributes="value
request/name|nothing">
<br />
<br />
Email address: <input name="email" type="text" tal:attributes="value
request/email|nothing">
<br />
<br />
<input type="submit" name="add" value="Submit">
</form>

The code for Register simply validates the input and calls a function
defined in an external module to send an e-mail to the person sending
the request, to verify ownership of the e-mail address.
This code is something like:

errors = []
name = form.get('name','').strip()
email = form.get('email','').strip()
if not context.validateForm(email, name):
    errors.append('- Problems occurred with input data')
if errors:
    errors.insert(0,'The following problems require correcting:')
    return context.register_index(messages=errors)

import md5
from Products.PythonScripts.standard import url_quote

sendEmail(['%s <%s>' % (name,email)],
    None,
    'Newsletter Registration Request',
    """
Thank you for requesting more information about our Newsletter.
Blah, blah, blah. To complete your registration please click on the link below

%s/register/Register2?email=%s&name=%s&hash=%s

Once you have done so, you will receive an e-mail confirming your registration.

If you have any problems please email %s
""" % (
        container.absolute_url(),
        url_quote(email),
        url_quote(name),
        md5.new('%s%s%sSomeHashHiddenPassword' %
(url_quote(email),url_quote(name))).hexdigest(), 			 
container.email_from_address),
      '')

return context.register_index(name=name, email=email, message="A
confirmation email has been sent to the address you provided.")

The problem I have is that the sendEmail() function always requires
the user to be logged in as manager of the portal to work. Whenever I
click on the "Submit" button, I am asked to log in and the code will
only proceed after successful log in. The same happens with Register2
that also sends an e-mail to confirm successful registration. When the
user receives the e-mail to confirm his data and clicks on the link,
he gets added to the database successfully and he should be sent an
e-mail. But again, that only happens if the user is logged in as
manager.
As I am new to zope I'm sure I'm missing on something important about
external methods, can anyone help?
Thanks in advance,
Squig.

In general you should not see and Unauthorized exception causing the popup
username/password request. First you should try to install VerboseSecurity 
to figure out any unauthorized issues and second don't import anything from 
PythonScript product when using external methods. The Python Library has 
the same methods (see Python Library Reference).

How about setting the proxy role of your Register script to 'Manager'? (to 
allow Register to invoke your external method)

Subject: [Zope] Problems with temporary connections
Message-ID: <3e429590507080751199496e2@mail.gmail.com>

I need to make a temporary connection to the ZODB.  I have really good
reasons relating to performance and not wanting have objects in the
current cache getting removed from the cache on why I don't want to
make use of the connections in the pool.  I can elaborate on this if
really nescessary...

The supposed way to get a temporary connection would be:

conn = Globals.DB.open(temporary=1)

which works fine.  The problem is that one cannot:
conn.close()

as this puts the connector back into the pool, where it shouldn't go
and if you do it, causes all kinds of nasty lockups, etc.

I have read some old posts that advise against using temporary
connectors as this can lead to memory leaks (as I can attest to after
trying to use them) and that temporary connections seem to be
"broken".

How can I get a connector, that will not be used by other normal
processes, that I can release cleanly when I am finished with it?  Or
at least ensure that one of the connectors in the pool is reserved for
a specific process and that that connector will only be used by that
process.  Can I do this by giving a "version" to the connector?

Any suggestions?

Does your technical expertise match your sense of humour? I have built
Python and Zope from source in the past, but that was always on a system
which had shipped with an earlier version of Python. In this case building
from source generates the following error when you start Zope. This was
python2.3.5 tar file from python.org and zope-2.7.5, from zope.org. All the
advice on the Web talks about removing old code, because DbTab is now
integrated. The error message was:

DBTab.ClassFactories.autoClassFactory could not be imported. Line 844 of
zope.conf.

Removing python-2.4 from the system is not an option. Too many thinks link
in to it.

I'm not sure if this is the case, but it looks like, for one reason or 
another, your zope is starting with a different python from the one with 
which it was compiled.

A problem I often encountered when having different python on a server, 
and with python compiled with enable-shared switch on (you can check 
this by running ldd against the python executable).

If the library path find is not correctly set, you will end starting 
your newly compiled python with another python library...

No need to remove anything. 
Just build python 2.3 and install it in /usr/local (the default).

Then build zope from source like so:

./configure --with-python=/usr/local/bin/python2.3 --prefix=...
make
make install

Does that not work?  I don't see why this is any different from
the usual case of the distro-provided python or zope being too old.

To simplify me statement: 
 - I've had problems with deb packaged zope's
 - other people complain about pre-packaged packages
 - building from source has a threshold hassle level worth taking
 - building from source is better if you're serious about your installation

When installing from the source, Python does offer a "make altinstall" which 
is terrific for installing a newer or older version of Python alongside an 
existing installation.
 For example, Fedore Core 4 comes with Python 2.4 and as far as I can tell, 
doing a "make altinstall" with the 2.3.5 tarball puts it alongside 2.4 quite 
nicely. At any rate, I've had no problems compiling, installing and running 
Zope 2.7.6 and 2.8 with it.

Subject: [Zope] DTML bug with database arrays in sqltest
In-Reply-To: <D5875D94F370470AA488173B@suxmac>
Message-ID: <F38C66ED-EFD2-11D9-A19D-000A27B3B070@eastlink.ca>

I am using arrays in Postgres. I need to be able to compare a string 
value in a specific position of a text array field (text[] is a field 
type in Postgres) against a variable(argument) I am passing to my 
query. I am only using  parts of the query to illustrate the problem as 
the rest is irrelevant. I replaced the table, field names and arguments 
with names that might make this more understandable.

First. I am finding arrays work fine with select statements in DTML 
when you use sqlvar to request a specific value from the array.

ie.

SELECT
	a_table.an_array_field[<dtml-sqlvar some_value type="int">][2]
FROM ....(rest of query)

But when you put them inside a sqltest tag for evaluating values it 
throws an error because DTML cannot parse it.

ie.

SELECT ...
  blah blah.....
<dtml-and>
     <dtml-sqltest column=a_table.an_array_field[<dtml-sqlvar 
an_array_key type="int">][2] name=a_title_var op="eq" type="string" 
optional>
..... (rest of query)

The issue is how to test against these values when DTML cannot parse 
them? My raw sql query works fine giving me the desired results but I 
cannot construct the statement in DTML.

The part of the query that throws the error is the dtml-sqltest tag (it 
gives a parsing error). ie.

<dtml-and>
      <dtml-sqltest column=a_db.an_array_field[<dtml-sqlvar an_array_key 
type="int">][2] name=a_title op="eq" type="string" optional>

should translate to:

AND
     a_table.an_array_field[1][2] = 'This is a title'  (This is a valid 
expression for Postgres)

where an_array_key is a variable with value of 1 and a_title is 
variable with a value of 'This is a title'

The above would give an invalid attribute name error for the 
an_array_key (variable/argument).

Is this a bug or is there something else I ought to be doing? If this 
is a limitation of DTML, is there a work around?

Regards,
David

If only it was that simple. It has always been that simple in the past, but
then my local python was newer than the one shipped with the distro.

I have not tried the --with-python argument, because the configure detected
my python 2.3.5 in /usr/local. Doing ./configure --prefix, make, then make
install didn't produce any errors, but attempting to run zope did. I will
try the --with-python argument next week, and the altinstall suggested by
another helpful person.

Many thanks for your support. I will feel much more comfortable with the
right version of python under my zope.

You cannot embed one dtml tag within another dtml tag.

A couple of possible work-arounds:

1) use a python script to return the values you need
2) create a python script which 'builds' a new dtml script and then execute the new script (ugly, but it works - not very efficient, so how often you run this will be a factor).

Do you mean external methods with db api for 1)?

I find I can use a plain statement like this in DTML ... but I cannot 
make it conditional.  To bad you couldn't use ZPT instead to make ZSQL 
methods since it is XML or even some kind of XML schema just for making 
queries. It wouldn't have to be that rich to get pretty much all the 
SQL commands in it.  You could embed as well this way so long as it 
validated.

AND
      a_table.an_array_field[<dtml-sqlvar an_array_key type="int">][2] = 
<dtml-sqlvar an_array_key type="string">

For 2) I am not understanding how a new dtml will solve this?

David

What type of object is "sendEmail"?

Have you (carefully) looked at the traceback (in your "error_log"
object -- you need to reconfigure it in order not to discard
"Unauthorized")?

The security manager could be changed (e.g. with "newSecurityManager").
"getSecurityManager" would report the change but not "AUTHENTICATED_USER".

Tim Peters (the current ZODB maintainer) warns against using
temporary connections. And I can tell you, he is right:

  I had to fix about half a dozen bugs in the handling
  of temporary connections.

You probably will not want to invest time in them because
the current ZODB (3.4) has dropped support for them altogether.

Whenever you get an "Error" (as the above one), you
*ALWAYS* should look at the traceback. You find it in the "error_log"
object (ZMI --> "Root Folder" --> "error_log").

"Unauthorized" are usually discarded. You must reconfigure "error_log"
to keep them.

Difficult "Unauthorized" problems are best analysed with
the "VerboseSecurity" product.

I have never had any problems with the Debian python packages, I suggest you 
use them.  Debian is perfectly happy to have 2.4 and 2.3 side by side (and 
2.1 and 1.5 even).  However, you should certainly build your zope and 
associated products from source.

I have sorted out the build from scratch. I installed python 2.3 as an
altinstall as suggested, and tried using --with-python on the zope
configuration. Both of these may have helped. Certainly, the suggestions
encouraged me to have one more go - and I found the problem! It was so easy
when I found it, too. I have a large number of existing zope instances,
each already has their own zopectl script. These were created before I
migrated to SuSE 9.3, so the script has PYTHON=/usr/bin/python. On SuSE
9.2 /usr/bin/python was python 2.3.

So, even though I built everything with python 2.3.5 the scripts were still
trying to use python 2.4 to run things. After I edited the scripts all was
well. That is on my test server. The production server has another 50 or so
Zope instances. It all makes work for the working man to do (as the song
says)

Thanks to everyone for their suggestions and support.
Tony

"newSecurityManager" ??
never heard of that. The __doc__ says
""" Set up a new security context for a request for a user """

What is this used for? I'm guessing it's something we use in unittests
and stuff.

Note that some weirdo have decided that "distutils" is a development
package, so you need to install both the python packages and the
python-dev packages, always.

It's used whenever some code has to act "as if" it was another user.

The only use I find in core Zope code is when a temporary container for
session objects calls its notify method. It does so as an anonymous user
instead of the logged-in one.

But third-party code can use it too. CPS does, for instance.

Subject: [Zope] CMF 1.5.2beta released
Message-ID: <21FB3040-1E5A-4BCE-9603-B392A2541048@dataflake.org>

Zope Corporation is pleased to announce the release of version  
1.5.2beta2 of the Zope Content Management Framework (CMF). This  
release is intended for testing purposes only;  we do not recommend  
deploying it to production servers.  The final release of version  
1.5.2 is expected mid-July 2005.

What is the CMF?

     The Zope Content Management Framework provides a set of
     services and content objects useful for building highly
     dynamic, content-oriented portal sites.  As packaged, the
     CMF generates a site much like the Zope.org site.  The CMF is
     intended to be easily customizable, in terms of both the
     types of content used and the policies and services it
     provides.

Where do I get it?

     Download it from http://www.zope.org/Products/CMF/CMF-1.5.2beta2

     Points of interest include:

     - "Windows ZIP file",
       http://www.zope.org/Products/CMF/CMF-1.5.2beta2/ 
CMF-1.5.2beta2.zip

     - "Unix tar/gzip archive",
       http://www.zope.org/Products/CMF/CMF-1.5.2beta2/ 
CMF-1.5.2beta2.tar.gz .

     - "Release notes",
       http://www.zope.org/Products/CMF/CMF-1.5.2beta2/README.txt

     - "Change history",
       http://www.zope.org/Products/CMF/CMF-1.5.2beta2/CHANGES.txt

     - "Installation instructions",
       http://www.zope.org/Products/CMF/CMF-1.5.2beta2/INSTALL.txt

Where do I go to learn more?

     The CMF mailing list (zope-cmf@zope.org) has many
     participants who are active in supporting the CMF.

...to report bugs?

     The "CMF Collector":http://www.zope.org/Collectors/CMF
     is the place to report bugs (please search for existing
     reports of your issue first!)

Message-ID: <9A3B396A-6A8E-492D-A067-4F896A7E8FBD@wattslawfirm.com>

I'm looking for ideas on how to implement a call logging/helpdesk  
ticketing system utilizing Plone.  Any ideas?  Before everyone  
responds "try PloneCollector," I'm looking into it.  However, I need  
some ideas, as I'm new to Plone (researched last couple weeks and  
installed yesterday).

I'm not looking for anything sophisticated, but useful.  I also saw a  
posting on the sf list that mentioned "mailmanager," so I'm looking  
into that, too.

Any and all help is greatly appreciated.

The download list at zope.org does not have any releases between 2.7.3 and
2.8.  We've been using 2.7.6 and would like to be able to download clean

I think you're going to need to guess the URL at the moment (shouldn't
be too hard)... the releases are there, they just don't show up in the
old releases list.

The download list at

    http://www.zope.org/Products/Zope/

has an entry for 2.7.6.  If you ended up at

    http://www.zope.org/Products/Zope/folder_contents/

instead, there's still an entry for 2.7.6, but it's on the second page
(click the "next 46 items" link near the upper right to get to the
second page).  Or go straight to

Thanks Chris, I found my master copy... but there are (I think) other
users.

Thanks Tim.  I'm not really sure where I was looking--I followed the 
standard download, then to the 'other releases" tab.  And the 2.7.X X>3
releases somehow were not visible

This is a problem of this half-baked software running on zope.org.

Yes, in fact...there seems to be a probllem with the command line 
parameters creating the tar file (which worked for me on FC3 but I am 
running FC4 since some days)...looking into it..

Subject: [Zope] Simple paypal IPN external method or product

Maybe you got it solved already, but here is some of my stuff (which 
works ;-):

I looked into PloneMall, but it's code is in some closed CVS and looked 
very complex. I decided to create my own shop starting from the product 
Simple Cart Item (by Aaron). In the end it was much expanded.


This is the code that does the PayPal checkout - largely stolen from 
the product Simple Cart Item:

from Products.PythonScripts.standard import urlencode

'''This is the digester for the cart string.  Currently this digester 
formats a
string to be sent to a Pay Pal gateway, but could be modifed for other 
gateways'''

portal_props=context.portal_properties
shop_props = portal_props.mshop_properties
shop_tool = context.mshop_tool

r= context.REQUEST
s = r.SESSION

# retrieve the cartList
cartlist=s.get("cartList", [])

# calculate items total
cart_total = 0.0
for item in cartlist:
     item_total = item['item_total']
     cart_total += item_total

# calculate payment costs (depends on items bought)
shipping= shop_tool.getPaymentCosts("paypal", cart_total)
shipping += shop_props.shipping


#cart preamble
cart_commands = {"cmd"           : "_cart",
                  "upload"        : "1",
                  "business"      : shop_props.paypal_business,
                  "currency_code" : "EUR",
                  "invoice"       : DateTime(),
                  "no_shipping"   : "0",
                  "handling_cart" : shipping,
                  "cancel_return" : context.portal_url() + 
'/sys/pp_cancel_callback',
                  "return"        : context.portal_url() + 
'/sys/pp_success_callback',
                  "image_url"     : context.portal_url() + 
'/pp_shoplogo.gif',
                  "notify_url"    : context.portal_url() + '/pp_ipn',
                  }


# formats cart items
l = 0

for item in cartlist:
     cart_item = item
     l+=1
     d ={'item_name_%d' % l : cart_item['name'],
         'on0_%d' % l       : 'variant',
         'os0_%d' % l       : cart_item['variant'],
         'on1_%d' % l       : 'maat',
         'os1_%d' % l       : cart_item['item_size'],
         'amount_%d' % l    : cart_item['price'],
         'quantity_%d' % l  : cart_item['quantity']
         }

     cart_commands.update(d)

#points to (sandbox) paypal account
if shop_props.paypal_use_sandbox:
     url = shop_props.paypal_sandbox_url
else:
     url = shop_props.paypal_url

context.plone_log("Commands send to paypal url (%s):%s" % (url, 
str(cart_commands)))

redirect_url = '%s?%s' % (url, urlencode(cart_commands))

state.setNextAction('redirect_to:string:'+redirect_url)
return state


=======================
This script calls into a plone tool (MShopTool): it is only a script to 
handle the callback from PayPal:

# MShopTool does the real work
mst = context.mshop_tool
result = mst.handlePayPalIpn(context.REQUEST)

=======================
This is the relevant code from the tool MShopTool:


     def handlePayPalIpn(self, request):
         log("Starting PayPal IPN")
         portal_props=getToolByName(self, 'portal_properties')
         shop_props = portal_props.mshop_properties

         #points to (sandbox) paypal account
         if shop_props.paypal_use_sandbox:
             url = shop_props.paypal_sandbox_url
         else:
             url = shop_props.paypal_url

         # copy the incoming form vars
         formvars = request.form
         # append validation command
         formvars['cmd']='_notify-validate'
         # remove Zope funny var:
         if '-C' in formvars:
             del formvars['-C']
         data = urllib.urlencode(formvars)

         response = urllib.urlopen(url,data).read()
         if response=="VERIFIED":
             log("PayPal IPN verification call: VERIFIED response. \n", 
formvars )
             self.notifyShopPayPalResult(formvars)
         elif (response=="INVALID" or 
formvars['receiver_email']!=shop_props.paypal_business):   # message 
compromised or not intended for us
             logerror("PayPal IPN verification call: INVALID response. 
\n", formvars )
         else:
             logerror("PayPal IPN verification call failed. \n", 
formvars )

You can emulate the "dtml-sqltest" with "dtml-if" and "dtml-sqlvar"
(or "dtml-var").

Subject: [Zope] Versioned connectors from ZODB
Message-ID: <3e42959050711033250134517@mail.gmail.com>

If I get a versioned connection from the ZODB:

conn = Zope.DB.open(version="myVersion")
root = conn.root()
app = root['Application']

# do some stuff

get_transaction().commit()
conn.close()

Are the changes now in a version?  How do I get those changes rolled
into the "trunk" version of the ZODB?  I guess all objects changed in
the version will now be "locked" to that version until I apply the
version changes to the trunk?

Thanks

Message-ID: <62304.84.146.154.231.1121082136.squirrel@xlhost.de>

hi all!

this is not my first posting regarding my "before_transaction_commit"
stuff, to summarize my plans:

make the transaction object call a method "_before_transaction_commit()"
on each changed object before the commit process starts.

in zodb 3.2 style transactions it seemed to be easy, changed objects
were stored in a list attribute of the transaction, attribute name was
'objects'.
now in zope 2.8 we have zodb 3.4 and everything is different, there
are managers/synchs to be registered, short question: how do i get
at the modified objects cleanly?

hope someone is fit in zodb hacking here :)

regards, juergen herrmann

ZODB versions are deprecated, unsupported, buggy and hard to use. Don't
use them.

This workaround is an excellent solution!  I am doing:

<dtml-if an_arg>
    and a_table.an_array_fieldt[<dtml-sqlvar an_array_key type=int>][2] 
= <dtml-sqlvar a_title type=string>
</dtml-if>

and just insert above any optional statements. Many thanks Dieter !!!!

David

Well that depends on your objective, and you haven't told us what you  
want to do from a functional point of view.

if you;re not tied to plone, and wants only helpdesk/ticketing system,
i'd recommend issue tracker product

it's actively developed, quite mature, silmple enough with many features

iirc, the url is http://www.issuetrackerproduct.com

So, after you get IssueTracker running, just add a link on your plone 
site page. Users wont know the difference.

Subject: [Zope] ldap authentication with apache or LDAPUserFolder?
Message-ID: <1121097613.3267.37.camel@localhost.localdomain>

As some of you know, I am working on an installation of Zope/Zwiki.
What I have inherited is a 2.5.1 Zope/Zwiki on a Debian box.  I am
wanting to move the data from the 2.5.1 to a 2.8.  But here's the
situation.

At the root of the 2.5.1 install there is an acl_users folder that
appears to be the LDAPUserFolder authentication mechanism.  However,
upon looking at the apache config on my Debian box you see this:

<VirtualHost X.X.org:80>
        <location /Zope>
        AuthName "Knowledge Access"
        AuthType Basic
        AuthLDAPURL ldap://X.X.org:389/o=X.org?uid?sub?(objectClass=person)
        require group cn=caitstaff,ou=Groups,o=X.org
        </location>
        DocumentRoot /var/www
        ServerName X.X.org

        RedirectMatch ^/$ /Zope/
        RewriteEngine on
        RewriteCond %{HTTP:Authorization}  ^(.*)
        RewriteRule ^/Zope/(.*) /usr/lib/cgi-bin/Zope/$1 [e=HTTP_CGI_AUTHORIZATION:%1,t=application/x-httpd-cgi,l]

</VirtualHost>

I am trying to figure out what is authenticating the user, LDAPUserFolder or the AuthLDAP in Apache?

In the root folder of the 2.5.1 install, there is our knowledge folder, argyle, inventory, a public folder.  Those are the custom folders
we created.
The Zope install folders are the control panel, temp_folder, Tutorial, test.  There is an acl_users folder, but
it is not the original and has the LDAPUserFolder configuration in it.  

After authentication, the user is directed to the index_html which is in the root folder.  The links present on this 
page point to our available knowledge bases (the custom folders we created).  As well, it has a manage Zope link.  Only certain users can access this link.
Anyone authenticated to the knowledge bases though, can add, edit or delete content.
This is the preferred method of this application as we want all users here to be able to openly collaborate.

I need to authenticate the same way on the new install as the old one.  Here is the dilemma though.
On the new install of 2.8, it rests on an RHEL4 server.  On this apache, I have to use authZLDAP
as there is a documented bug with RedHat for the AuthLDAP.

There are years of data collected in this knowledge base that I don't want to lose.  So I am being 
about as careful as I can be...maybe too careful.  

So, question wise...I am wondering what authentication to use.  I know that LDAPUserFolder appears
to be the way to go, but I don't know if that is what is actually happening.  By the looks of the above 
apache configuration, could there be some sort of redirection happening?

And as I understand, so are temporary connections too.  That leaves me
with getting a "normal" ZODB connection from the pool which I don't
want to do.

I really need a "temporary" connection that I can discard.  This
connection can have a much smaller cache than the normal connections
as it makes very little difference in the speed of data loading. 
Second prize is a connection that will only be used by a specific
process and never used for other processes.  Versions solves this for
me.

I can check out a connection and keep it aside only for data loading. 
But this means that I waste precious memory on a connection that does
not really need to cache the amount of objects that the other
connections should.  In my case, this translates to using 1GB of RAM
on one connection that gets used once a day.

Please believe me that I really need a "special" connection.  For
those who really want to know why, below is an attempt at an
explanation why:

In the application that I have written, I want to be able to get
connections that are not part of the normal connection pool.  Once my
process is finished, I can store these connections for later use, or
discard them.  Currently my application uses the normal connections in
the pool.  The problem is that this process "contaminates" the cache
of the connections with objects that are not used in "normal" client
application use (I use a thick client).  This means that the client
applications are extremely slow the next day and that it takes a long
time before the cache contains the often used objects again.

>From there the reason why I DON'T want to use the connections for my
once a day data loading process.

My ZODB contains about 700`000 objects.  A connection caches about
60`000 objects to give satisfactory client speed.  To start up the
client before the cache is initialized, takes about 5 minutes.  Once
the cache is populated, it takes a client seconds to start up.  Data
loading invalidates all of this, but is worse than a "clean" cache in
that it takes long for the "new" objects in the cache to be flushed
and replaced by the often used objects again.  Data loading does not
need such a big cache since it mostly loads data into the ZODB. 
Unfortunately, the loaded objects also end up in the cache.

Why do I need so many objects in the cache?  Some searches cannot be
done with a mere ZCatalog search and have to run through a subset of
all the objects.  These tend to fit nicely in the cache.

How can I manage permissions for imported ZPT files?

Relevant lines from my Product:

from AccessControl import ClassSecurityInfo
class MyClass(....):
  security=ClassSecurityInfo()
  comment_add_form=PageTemplateFile('zpt/comment_add_form',globals())

My goal is to limit access to comment_add_form to the Authenticated role 
only. comment_add_form is on the filesystem, in my Product's zpt directory.

How can I achieve this? I understand zilch about ClassSecurityInfo...

(My Product is based on JMBoring template)

Why don't you just *try* different combinations and see what happens?  
Like, comment out the Apache AuthLDAP stuff and see what happens.

Your query would be better served on the zodb-dev list, where Tim Peters
hangs out;  he can probably explain how to get what you want without
guessing.  If I had to guess, I would suggest constructing your
connection programmatically, where you can specify the object cache size
for instance, and then closing / discarding the connection when you are
done.

add a security.declareProtected('comment_add_form', '<right that is

Where the second string would be one of the rights listed on the
security tab with in the ZMI. If that right is granted to the
authenticated user only, you have your access restrictions.

It's the other way around. Permission first, then the method name.

What I suspect is that you are working with Zope in Remote User Mode. 
You can verify this in a very quick way, by looking at your instance 
home directory and checking if the access file contains a line like 
'admin:' or 'super:' or whatever, but with no password.

Subject: [Zope] ldap authentication with apache or LDAPUserFolder?
Message-ID: <1121104873.4554.4.camel@localhost.localdomain>

Sorry Marco the reply to all button eluded me once again:

I deleted the access file and recreated it so I could get ready to
delete all instances of the old LDAPUserFolder.  This has to been done
prior to migration of Data.fs as the new Zope 2.8 isn't compatible with
the old LDAPUserFolder.

Now, after commenting out the apache lines below:

  #<location /Zope>
        #AuthName "Knowledge Access"
        #AuthType Basic
        #AuthLDAPURL ldap://X.X.org:389/o=X.org?uid?sub?
(objectClass=person)
        #require group cn=caitstaff,ou=Groups,o=X.org
        #</location>

I can type in the URL for the knowledge base and it takes me straight to
the index_html page without authentication unlike before.  However,
after clicking the Manage Zope link, then you must enter in credentials,
in order to access the ZMI of which the root folder contains the
acl_users folder with the LDAPUserFolder configuration.  Does this tell
me that LDAPUserFolder is being handed the credentials via apache
through some sort of redirect?

Maybe like death would solve my problem with overdue taxes <wink>.

Connection pools are associated with DB instances, so if you want
connections with different characteristics, create another DB
instance.  Like, e.g., in the ZODB 3.2 line,

    otherdb = ZODB.DB(storage, cache_size=100, pool_size=2)

Then connections obtained via otherdb.open() will hang if two threads
already have connections from `otherdb` (that's the effect of
`pool_size`), and will have ZODB memory caches that strive to keep no
more than 100 objects in memory across transaction boundaries (the
effect of `cache_size`).

This is easiest if you're using ZEO (ClientStorage), because doing
otherdb.close() also calls close() on the DB's storage.   If you,
e.g., share a FileStorage directly across multiple DBs, closing any
one of the DBs will close the FileStorage across all the DBs using
that FileStorage.  ZEO makes it easy to open multiple ClientStorage's
"on top of" of a single FileStorage, which can be closed
independently.  If you never close otherdb, this isn't an issue.

This answer assumes you're using ZODB directly.  I don't know details
of how to spell it from within a Zope application (if that's what you
need -- unsure).

I actually found this recently myself :-)

I found that once I hit the "earlier transactions" link once, having 
opened the main ZMI frame in it's own window/tab, I could see the URL 
being used to do the batching.

 From that, I tweaked the URL to show many more transactions per page 
and so was unable to undo a lot of transactions in a way very similar to 
that you describe.

The hardest part was selecting all the right checkboxes ;-)

Indeed, but should ZPT Python Scripts really be so sensitive to line

Failing that, just log to seperate files and have a periodic cron jop 
staple them all together. AWStats comes with a very efficient script for 
doing just this :-)

(see stats.zope.org ;-)

I did get the versioned connections to work (so far), BUT, I will
definately take your word on it and seek another solution :)

to double check:

otherdb = ZODB.DB(existingdb._storage, cache_size=100, pool_size=2)

is ok?  It seems that you can create more than one DB instance that
shares one storage object.

I hit upon the idea of creating another DB instance and sharing the
storage object myself yesterday, but wasn't sure what the
repurcussions will be.  Your post answers most of my questions.

 I have one left, though:  if I do decide to share the storage object
(and not go ZEO for whatever reason), will the caches between the two
DB objects not get out of sync?  In other words, will one DB object
know to invalidate objects in it's caches should that object be
changed through another DB instance?  I know ZEO does this for you,
but I'd like to know what the case would be for two DBs in one
process.

My other option is to create the connections "by hand" (that way I can
control the cache size easily) and keep my own little pool of
connections with a modified close method that does not put my
connections back into the "normal" pool.  But I'm afraid I may end up
with a new can of worms that way.

I use the ZODB directly, but from within Zope.  The connections are
used in long-running processes that are not nescesarily
browser-triggered.  Some of them are scheduled events that are started
up in their own thread.  From there the need to get new connections to
the ZODB.  I have quite a bit of experience working safely with
multiple threads and the ZODB, so I'm sure I have that part right.  My
problem had more to do with "cache contamination" and reserving
"special connections" for specific processes.

Thanks for the reply

My questions are :

Now I understand that I have reinvented the wheel :(
SimpleUserFolder was what I should I found BEFORE I developed my
IssueUserFolder for the Issuetrackerproduct.
Just one python question Chris, why do you do this::
class User(BasicUser):
    def __init__(self,dict):
        # bypass immutability
        d = self.__dict__
        d['__'] = dict['password']
        del dict['password']
        d['name'] = dict['name']
        del dict['name']
        d['roles'] = dict['roles']
        del dict['roles']
        d['extra'] = dict

What's wrong just doing 
self.__ = dict['password']
??

Subject: [Zope] LDAPUSerFolder permission problem
Message-ID: <42D3BF87.6050103@deakin.edu.au>

I'm trying to access the getProperty() method of the LDAPUser class in a 
Python script, in order to access the Active Directory email address of 
the user.

There is no problem with this, if I use the method on the current active 
user. However, it doesn't work when I attempt to use the method on 
another property.

The output of VerboseSecurity is:

*Error Type: Unauthorized*
*Error Value: Your user account does not have the required permission. 
Access to 'getProperty' of nwuser denied. Your user account, abuser, 
exists at /acl_users. Access requires one of the following roles: 
['Manager']. Your roles in this context are ['Anonymous', 
'Authenticated', 'User'].*

It appears that the currently authenticated used has the 'View' 
permission (required to use getProperty) on itself, but not for other 
users. I'm not sure how to change this.

In order to get around this problem, I've tried giving the script a 
Proxy role of Manager. However, when I do this, i get the following 
output from VerboseSecurity:

*Error Type: Unauthorized*
*Error Value: The owner of the executing script is defined outside the 
context of the object being accessed. The script has proxy roles, but 
they do not apply in this context.. Access to 'getProperty' of nwuser 
denied. Access requires one of the following roles: ['Manager']. The 
executing script is (PythonScript at 
/DCARF/Forms/initialContact/initialContact), owned by admin1.
*

**
I'm not sure why this is occurring. Giving the script a proxy role of 
Manager should get around the first problem, but I'm not sure why it 
doesn't.

Any ideas what is causing this?

I'm assuming that the "other" user is not wrapped. How are you  
getting that other user object?

Message-ID: <20050712144326.43897.qmail@web26310.mail.ukl.yahoo.com>

Hi everyone,

I'm a beginner in Zope. I've just installed the Zope 2.8 final package.
The installation seems to have completed normally.
However when the zope instance is run I have the following message :

There was no previous message with keyword "loghandler" in the mailing list.
All Zope services are stopped.
Here are the system variable that are relevent :

The Zope instance is the one created by the install package.

Seems that something is not working with my configuration, but what?

That's probably your luck. They are deprecated, unsupported, and  
carry the risk of data loss. So you should not be using them, anyway :)

In fact, Charlene probably can't figure out how to sue them because
newer versions of Zope have removed them completely. :)

Books about fast-evolving software always carry the big risk of  
becoming at least partially obsolete quickly. Not much one can do  
about that.

Sure it is.  For zope 2.7.5 look in lib/python/ZServer/FTPServer.py on
line 484.  Change the text to be whatever you want.  No recompilation
necessary (just restart zope)!  (I just happen to have 2.7.5 handy on
the machine I'm sitting at right now)

I don't know.  Perhaps you can add a line in there to invoke a 'cwd'
command.  Most likely you can, if you read the code enough to
understand what it is doing.  (it's python code, it's not that hard to
read :-))

it) if there isn't

No, it means that the index_html object has the View permission
granted to Anonymous.  Therefore zope didn't need you to authenticate
because you already had enough privileges.  The other option is that
your browser remembered your credentials for that site and submitted
them without asking you.

If that works for you, don't let nay-sayers scare you away.  I don't
think there are any reports of version bugs open in the Zope collector
at present -- but that could just mean that everyone stays away from
them now.

The code won't stop you from doing that, but as I said last time, I'd
use ZEO and use a fresh ClientStorage for each DB.  ZEO was designed
to support this kind of use; nothing else was.

Neither am I, if you don't use ZEO.  Normally I'd spend time digging
into the code trying to find answers, but I don't have time for that
today.  It's possible that if you asked on the zodb-dev list, Jim
Fulton or Jeremy Hylton would know more answers off the tops of their
heads.  Sorry, but I don't.

At least the ZEO part did <wink>.

See above:  ZEO should work fine.  If you try to do it without ZEO,
I'm not sure what will happen.  I pointed out one "obvious" bad
consequence of trying to share a storage last time (that closing any
DB will close the storage across all DB's sharing that storage).

In general, invalidations get sent out by a DB, to all (& only) the
connections obtained from that DB.  So yes, if you're not using ZEO
(which goes on to broadcast invalidations to all connected clients),
caches can get out of synch across DBs.  But I don't know whether that
matters to you either.  For example, perhaps you're willing to create
a new DB whenever you need a temporary connection, and what you do
with it then is read-only and finishes quickly, or ... I just don't
know.

I'd definitely advise against that.  The Connection constructor isn't
meant to be called outside of ZODB internals.  Note that you can't
even call it without passing a db, and there's an intricate dance
between Connection and DB methods that's mostly undocumented and hard
to get right.

Since there's no machinery aiming specifically at that, I'm afraid
it's bound to be painful one way or another -- except that, using ZEO,
it sounds quite straightforward.

Well, there's a reason for PData ;-)

str'ing a large file will use lots of memory...

str'ing lots of large files in one transaction will topple your machine!

The community has grown averse to using versions because they interact
poorly with content catalogs (by locking the individual BTree buckets in
the catalog's indexes).  If Etienne's need doesn't involve touching the
catalog, or if he can affort to do catalog-munging updates only within a
version, then versions will work as designed.

They are still a nice way to experiment with customizing ZPT, etc.
(which won't typically touch the catalog).

Message-ID: <42D4BAD7.60109@berlinger.cc>

Hi,

I want to update from Zope 2.7.4 to Zope 2.7.6

What is the easiest way?

Unfortunately there is no description of how an update of Zope is done. I'm running Plone on it. I tried to newly install Zope 2.7.6 and then copied the backed-up Data.fs file and the content of the Products folder. It didn't work very well. There should be no version conflicts with Plone as I checked on the Plone web site.

Thanks for any advice!

Josef

Subject: [Zope] Cool monkey patch to make tracebacks more useful :-)
Message-ID: <42D4D386.3020202@simplistix.co.uk>

Hi All,

Ever noticed how tracebacks from ZPT are actually quite useful when 
viewed through the error_log object, but totally useless when they fail, 
say, in a unit test?

This bugged me, so I had a dig, and just discovered this cool monkey 
patch, to be inserted in any module that gets imported before an 
exception is raised:

import traceback
from zExceptions.ExceptionFormatter import format_exception
traceback.format_exception = format_exception

So now I'm mailing you lot for two reasons:

1. This makes life a lot easier when debugging failing unit tests and 
looking through entries in event.log that have tracebacks, so I thought 
I'd share it :-)

2. I wonder if there's anything bad that can happen as a result of this?

If the answer to 2 is "no", then I'm gonna wrap this up into a minute 
product...

cheers,

Chris

So, could this be in the unit test module itself, for example?

And a question for you:
Ever noticed how it's near impossible to figure out what actually
causes an error when you run functional tests? Can you fix that too?
:-)

I used to do this in all my functional test cases:

    def getTraceback(self, response):
        return getattr(response._response, '_text_traceback', None)

    def assertResponse(self, response, status, message=''):
        if not response.getStatus() == status:
            tb = self.getTraceback(response)
            if tb is not None:
                raise self.failureException, tb
            else:
                raise ValueError, "Response had status %s, expected %s. %s" % (
                    response.getStatus(), status, message)

And then end all my tests with:
        self.assertResponse(response, 200)

And that _used_ to print out any exception that had occurred, but in
newer version of Zope this never happens. There sinmply never is and
_text_exception on the response anymore. Any ideas on how to get a
useable exception report on unit tests?

I might use the CookieCrumbler. You can pass username and password as form

"Didn't work very well" is not a good description of a problem.

You should be able to replace the existing Zope SOFTWARE_HOME with a new 
version. (I don't know if over-writing is safe; I wouldn't count on it.) 
This may be easiest.

You should also be able to install Zope in a different location, create 
a new instance, and copy over the config files, products, and Data.fs of 
your old instance.

(All this is because the instance scripts point to a specific 
SOFTWARE_HOME. You could also change that.)

Recently I had to move a Zope (Plone 2.0.x) instance, and I have found
that I can't just move the Data.fs. It stores several absolute paths
that become broken if the paths of the things (like of some files in
products) changes. So finally I have exported the objects (PloneSite
objects), and imported them into the new instance. It worked, however
then the user name of the last modifier of the objects was replaced with
the name of the user who did the importing /-: (while the last
modification date has remained intact -- strange). (Also, I seems one
have to be careful to create the same users in the /acl_users than in
the old instance, otherwise the exported stuff will have some strange
security errors.)

As announced earlier elsewhere, Hurrah, Inc. will cease all Zope hosting 
activities effective August 12, 2005.

I sincerely thank all the members and contributors of the Zope community, 
past and present, and especially Zope Corp for their creation and 
continued support of the Zope product. I've watched quietly from the 
sidelines as Zope and its supporters accomplished a lot in the last six 
years, and I wish all the best in the years to come.

I'd also like to take this opportunity to say I'm a big fan of PCGI for 
stable, simple, shared Zope hosting. Yes, I'm the one, and it was used on 
every single Zope instance I ever had my hand in creating, including Zope 
2.7 versions. So the next time someone mentions that only crackpots would 
use PCGI, feel free to refer to me by name. I've enjoyed using it.


I welcome all comments/questions/concerns at comments@hurrah.com.

I'm not sure what you mean by a 'wrapped' user. What causes a user to 
have a wrapper in Zope?

I am getting the 'other' user via the following code:

user = context.acl_users.getUserById(username)

Will this cause the user to be returned with a wrapper, and if so, how 
would I remove the wrapper?

Thanks.

Hello,

How it is possible to wrap the response of a subtree?
For example, for the path /foo/bar/baz, a script located at
/foo/wrapper would catch the output of the rest of the request path
(./bar/baz) and do a transformation upon it (gzip, xslt, etc).

Thank you,

Ah, so Google is blocked by your corporate firewall? ;-)

And rightly you should, since this list is neither centered around Plone

try looking for breadcrumbs.py in a script or two, I can't promise that 
Plone hasn't bastardised it, but it's what the CMF used to use to 
calculate breadcrumbs...

Sorry, I can't reproduce this, on Win XP Pro SP2:

C:\Zope-Instance\bin>runzope.bat

C:\Zope-Instance\bin>"C:\Zope-2.8.0-final\bin\python.exe"
"C:\Zope-2.8.0-final\lib\python\Zope2\Startup\run.py" -C
"C:\Zope-Instance\etc\zope.conf"

and that's it -- Zope is running at that point, and there's no more
console output.  \Zope-Instance\log\event.log shows "Zope Ready to
handle requests", though.  You may find more clues in your event.log.

> There was no previous message with keyword "loghandler" in the mailing list.
> All Zope services are stopped.

Why the plural ("services" as opposed to "service")?  Do you have more
than one Zope installed?  Installing Zope installs exactly one Windows
service (if you allow it to), so I expected to see the singular
"service" here.  Not trying to be picky for the sake of it, but there
must _something_ different in your system from what others are doing.

Those look normal.  Did you change \Zope-Instance\etc\zope.conf in any way?

Same for me above.

> Seems that something is not working with my configuration, but what?

I don't know, and I haven't seen this reported by anyone else before. 
Let's try this:  cd to your Zope's (not Zope-Instance's) bin
directory, and start Python from there.  Your DOS box should look like
this then:

C:\Zope-2.8.0-final\bin>python
Python 2.3.5 (#62, Feb  8 2005, 16:23:02) [MSC v.1200 32 bit (Intel)] on win32
Type "help", "copyright", "credits" or "license" for more information.
>>>

Then type in "from ZConfig.components.logger import loghandler", to
try the same import you got a complaint about before.  Here's what
happens when I do that:

>>> from ZConfig.components.logger import loghandler
>>>

That means the import worked fine -- and it should work fine.  What
happens when you try it?

Message-ID: <42D6397A.22742.2A8F60E@localhost>

Hi. I've posted this in more detail before, but the general processs 
i've been using to update Zope lately is:

# Backup <path-to>/Data.fs
# Put the new zope tarball somewhere like...
cd /home/myhome/src/zope/276/<zopesrcname>
gunzip <zopesrcname>.gz
tar -xvf <zopesrcname>.tar
mv <zopesrcname> zope276
cd zope276
#Assuming you want to put your new zope in /var
#Assuming you have a recent python
./configure --prefix=/var/zope276 --with-python="/usr/bin/python2.3"
make
make install

# Assuming your prior zope version is still running and that it
# is installed as a service.
service zopectl stop

change references in /var/zope-instance/bin/zopectl
change references in /var/zope-instance/bin/runzope

service zopectl start

# This way I can leave prior versions of zope on the system in 
# case I need to revert. For instance, I had lots of legacy 
# and Plone problems with 2.8 so went back to 2.76 by just
# changing references in zopectl

I hope that helps.

Hi David

We are using the combo, although in a very plain form. We use a  
custom table for users and have implemented any additional  
functionality in our own way. So we use XUF/pg for handling security  
in Zope. This works on global roles, assigned in the table record,  
but also with local roles assigned to users in the ZMI.

Nice thing is: You can add multiple instances of XUF in different  
folders all pointing at the same pg table.

Summarising: We like XUF a lot, but do not use most of its advanced  
stuff. We have had no security or performance issues (but then our  
Postgresql server has RAID and 2 CPUs).  Also, Andrew Milton (author)  
is very helpful in answering questions on the mailing list.

IIRC. you can just use <dtml-var testString newline_to_br>
to get the same result.
I know of no occurence where you have either \n or \r
but in the same string (and not just \n or \n\r)
But if you want to replace each, either:

<dtml-var expr="testString.replace('\r','\n')" newline_to_br>

or

<dtml-var
expr="testString.replace('\n','<br />').replace('\r','<br />')">

but beware the quoting.

Even better maybe you just use CSS for your layout:

<p style="white-space:pre">
<dtml-var testString>
</p>

or with ZPT:

<p style="white-space:pre" tal:content="options/testString">
Sampletext
</p>

Once, they caused data loss due to a bug introduced during a ZODB
restructuring...
This bug was fixed a long time ago.

Packing, too, once caused data loss (another ZODB bug, also fixed a long time
ago). Should we no longer use packing because of this?

You can import them as soon as you execute the necessary security
declarations (--> "PythonScripts" --> "README").

In order to let Zope's "logging classes" log to postgres, you
will need to implement a new log handler that does this...

I had a similar experience but solved it by modifying
"zLOG.EventLogger.log" in the following way:

# DM 2005-06-27: Zope style tracebacks
from zExceptions.ExceptionFormatter import format_exception
....
        # DM 2005-06-27: we now use Zope's traceback format because
        #  it is more informative
        #self.logger.log(level, msg, exc_info=(error is not None))
        exc_class = sys.exc_info()[0]
        if error and exc_class is not None: # Note: "error" is a boolean!
            msg += '\n' + ''.join(format_exception(*sys.exc_info()))
        self.logger.log(level, msg)


Maybe, code like this should move into the Zope core?

I solve this with a browser emulation that does not use HTTP for requests
but instead emulates "ZPublisher.Publish.publish" and therefore
can handle exceptions itself. It somehow looks like this:

  def _internalRequest(self, path, query, method, headers, request_params,
                       catch_exc, response,
                       ):
    '''perform a request against the internal *url*.'''
    from Zope import zpublisher_exception_hook as err_hook
    from Zope import zpublisher_validated_hook as validated_hook
    try:
      # Note: we should use the checkpoint feature, new in ZODB 3.3
      #  Unfortunately, we still use ZODB 3.2...
      #  Without this feature, we cannot reliably undo the effects
      #  of failed requests (we try with subtransactions)
      request = self._makeRequest(path, query, method, headers, request_params)
      zope_response = request.response
      object = request.traverse(request['PATH_INFO'].strip(),
                                validated_hook=validated_hook,
                                )
      result=mapply(object, request.args, request,
                    call_object,1,
                    missing_name,
                    dont_publish_class,
                    request, bind=1,
                    )
      if result is not zope_response: zope_response.setBody(result)
      get_transaction().commit(1)
    except:
      try:
        # Probably, we need special treatment for 'raise redirect'
        if not catch_exc or err_hook is None: raise
        response._setException()
        # we learned from Malcolm that 'err_hook' always raises an exception
        try:
          zope_response = err_hook(request['PARENTS'][0], *exc_info())
        except:
          # Note: we do not handle "Retry" (as it is very unlikely)
          zope_response.exception(*exc_info())
      finally: get_transaction().abort(1)
    response._setFromZope(zope_response)

Hi Dieter.  I realize that external methods are needed in most cases to 
import into a Script Python.
I was hoping perhaps logging might be one of the classes that could be 
imported without going to external methods.

Thanks.  I guess my big decision with this was whether I ought to use 
what already exists in Zope or use python's logging class.  Either way 
I have to write something to handle, store, retrieve the logs for sure.

Why? For any kind of real load at a helpdesk, Plone is totally the wrong 
solution for scalability reasons.

I'd certainly try MailManager 2.0, it's built to handle the kind of 
loads you're likely to experience here...

I use it but in a very hacked up form because I need inline auth
and I wanted sha1 hash instead of the default crypt.

BTW, the 0.50.x branch has pluggable crypt types..

crypt, md5, sha are part of the crypts you can pick.. or you can write your
own in about 30 seconds if you need something else.

No, it's the other way around. You want the wrapper. getUserbyId  
returns unwrapped users.

If you use CMF or something based on CMF you could use the membership  
tool's getMemberById to return something more useful, otherwwise  
you'll have to do the wrapping yourself:

user = acl_users.getUserById(user_id).__of__(acl_users)

Well this sha1 patch wasnt the real hard work ;-)

Inline auth was the real nut to crack. And the fact XUF returns HTML
instead of using appropriate exceptions add to the complexity :-)

I hope PAS will fill the gap although it isnt yet ready for prime time.

How do you mean "unable"? That's not a very good problem description.

RESPONSE.redirect is simply a Python method, and it will take any string 
you can manage, no matter where it comes from. In fact, I think it would 
be very difficult to do otherwise.

You must, of course, pass the value of a variable, and not the variable 
itself. None of the following pose any problem::

  REQUEST.RESPONSE.redirect("http://plone.org")

  url = "http://plone.org"
  REQUEST.RESPONSE.redirect(url)

  def redir():
    return "http://plone.org"
  REQUEST.RESPONSE.redirect(redir())

  urls = {}
  urls['plone'] = "http://plone.org"
  REQUEST.RESPONSE.redirect(urls['plone'])

  REQUEST.RESPONSE.redirect(urls.get('plone', "/"))

In fact, they should all work identically.

You might want to take a look at SimpleUserFolder. It's a lot more light 
weight that XUF and handles RDB-based auth of any variety really well...

I'm not looking at the code as I write this, so I may be wrong, but I do 
that because, if you look further down, you'll see I define a 
__setattr__ hook that raises an exception, since seeing attributes on 
object of this type is a really bad thing to do, so you have to go 
through lots of hoops if you really want to do it ;-)

For something as specialised as this, I'd just insert appropriate calls 
to appropriate ZSQL methods where you need them.

The logging framework is great when you want to be able to switch where 
log entries are written in a more dynamic fashion, or enable other users 
of your code to decide to log to a different place.

You, however, want to log into postgres only, as best I can see, so 
there's no point in fighting the security restrictions in your 
particular case ;-)

That said, it'd be great if you could at least do:

from logging import getLogger
logger = getLogger('event.something')
logger.log('something')

...without loads of unauthorized errors popping up :-S

cheers,

Chris

For simple conversion, you may find htmldoc to be a good choice.
Reportlab is a great tool but takes considerable effort; htmldoc
gives a "good enough" solution in many cases.

I'm interested to know what you find its shortcomings to be.  I know it
is in use in production on some fairly large sites (dozens of content

After logging out of the ZMI, I have tried to log in as the emergency

there be a tick I am missing in the security settings for the root

There are several products to do this: LocalFS, ExtFile/ExtImage, 
ExternalFile, and more.

There are other methods (like writing an External Method and using 
Python's file methods) as well.

All of this has been discussed on this list and elsewhere, and are 
otherwise described on the web.

For what it's worth, I recently used the SimpleUserFolder for an
application that uses Postgres as the backend.  It was terrifically
easy to implement authentication through Postgres via the
SimpleUserFolder.  It does exactly what I want without unnecessary
frill or complications.

I like this one too :-)

That just leaves the traceback printed by pdb, anyone reckon they can 
get that to use the sensible formatter? ;-)

*shrugs* I'm quite happy with it as a product that I can add and remove

Well, like I said, I'm gonna roll up a load of these type patches into a 
little product and release it :-)
(the benefits of this product would only be missed if an error occurred 
before it was imported, and the benefits aren't likely to be very 
beneficial at that stage ;-)

Hmm, if something failed, I'd just consult the event log, which I always 
copy all errors to.

Sounds good, but we use Zelenium ;-)

Ugh? on unit tests? my patch works exactly as I want on unit tests.

Well, if you make 'foo' a python script or page template, /bar/baz will 
be available in the traverse_subpath variable and you can do whatever 
you want with them :-)

Hi Garth. Yes, it is very compact compared to XUF for sure. Thank you 
for this feedback. I will be evaluating this option as well.  There are 
differences in licensing that may be a factor in what I decide to use 
after some evaluation.  BSD with XUF compared to MIT with 
SimpleUserFolder.  I have tended to stick with ZPL and BSD only 
sources. I try to learn from GPL-like sources as opposed to using them 
in my code. This may be a factor in my decision despite the fact that 
SimpleUserFolder may be smaller and simpler to implement.

Regards,
David

Can anybody give me a hint?

Something like this should work (taken from zopewiki.org):

In [10]?: from AccessControl?.SecurityManagement? import 
newSecurityManager, getSecurityManager
In [11]?: user = app.acl_users.getUser('jean').__of__(app.portal.acl_users)
In [12]?: newSecurityManager(None, user)
In [13]?: getSecurityManager().getUser() # just to verify it.
Out[13]?: jean
In [14]?: app.fab.materials.invokeFactory('Material', 'test11')
In [15]?: mat = getattr(app.fab.materials, 'test11')
In [16]?: mat
Out[16]?: <Material at /fab/materials/test11>

Do you get a traceback by "pdb"?

   I only get information of the form
   "*** TypeError: <exceptions.TypeError instance at 0x405e0cac>"

This is even more stupid than Microsoft error messages.


Today, I have been so annoyed by this that I decided to
improve "pdb" in this respect and donate the patch
as a feature for the Python core...

Subject: [Zope] Creating Photo object from an Image object
Message-ID: <42D9510B.1040002@onlinehome.de>

Hi,

I have a problem with the "Photo" product. I want to create a Photo 
object from an existing Image object.
I have a form with id and title input tags which are initialized with 
appropriate values from a special folder where
the Image objects resides
.
Now I have written a PythonSript to handle the creation of a new Photo 
object
#id1,title1  image id and  tile
def doAddPhoto(id1, title1):
    # some comments
    ....
   
    img = context.getObjectById(id1) # this returns the object part of 
object item array from context.objectItems
    s="ph" +str(id1)   
    context.manage_addPhoto(id=s, file=img.data,title=title1, 
displays=None, precondition='', content_type='image/jpeg') (line 12)


If I submit the form, an error occurs:

Traceback (innermost last):
  Module ZPublisher.Publish, line 101, in publish
  Module ZPublisher.mapply, line 88, in mapply
  Module ZPublisher.Publish, line 39, in call_object
  Module Shared.DC.Scripts.Bindings, line 306, in __call__
  Module Shared.DC.Scripts.Bindings, line 343, in _bindAndExec
  Module Products.PythonScripts.PythonScript, line 323, in _exec
  Module None, line 12, in doAddPhoto
   - <PythonScript at /www.ecommerce.de/doAddPhoto>
   - Line 12
AttributeError: manage_addPhoto


When I try it with context.manage_addImage everything works fine.

I can't figure out why the above Exception is thrown, the source code
of Photo's manage_addPhoto function looks as similar as the
manage_addImage function of the Image class (from which Photo is derived)
and i have no clue where the pitfall is.

Does anybody have an idea or a hint?

Help would be appreciate.

Thanks in advance

Thomas Adams

Subject: [Zope] numeric formatting
Message-ID: <42D97BE3.603@earthlink.net>

Hi List,

I will have to format numbers based on country and currency types.

I understand the locale module can do this.  I've done some googling on 
this but cant seem to get anything definitive.  I've read that the local 
module is not thread-safe but I do not know how this would impact my 
Zope app.  I do know that I would want to be able to change from one 
currency format to another depending on which currency conversation the 
user may want.

Really my question is, what approach is recommended for a Zope 
application to format numbers according to currency type? 

David

Message-ID: <E28F8119-F651-11D9-8AA1-000A27B3B070@eastlink.ca>

I want to test for a value of a folder property to conditionally 
include css in a css.dtml
instead of putting a condition on the whole css file in zpt or adding 
additional css
to unstyle and restyle in some classes in same skin.

Something like this...

<dtml-if 'here.my_property == some_value'>
some css here ...
<dtml-if>	

Can someone advise of a way of getting property for comparison directly 
without having to
write a script python to return context.my_property. I have to say I 
really only use
dtml for zsql so it is a bit foreign compared to ZPT. I could not find 
anything
in Zope book about getting a folder property without knowing the folder 
name first.

Message-ID: <96B916C7-8024-44E1-A7D4-008F2A8E65E5@dataflake.org>

Zope Corporation is pleased to announce the release of version 1.5.2  
of the Zope Content Management Framework (CMF). This release marks  
the latest stable release in the CMF 1.5 series and should be  
suitable for production use.

What is the CMF?

     The Zope Content Management Framework provides a set of
     services and content objects useful for building highly
     dynamic, content-oriented portal sites.  As packaged, the
     CMF generates a site much like the Zope.org site.  The CMF is
     intended to be easily customizable, in terms of both the
     types of content used and the policies and services it
     provides.

Where do I get it?

     Download it from http://zope.org/Products/CMF/CMF-1.5.2

     Points of interest include:

     - "Windows ZIP file",
       http://zope.org/Products/CMF/CMF-1.5.2/CMF-1.5.2.zip

     - "Unix tar/gzip archive",
       http://zope.org/Products/CMF/CMF-1.5.2/CMF-1.5.2.tar.gz

     - "Release notes",
       http://zope.org/Products/CMF/CMF-1.5.2/README.txt

     - "Change history",
       http://zope.org/Products/CMF/CMF-1.5.2/CHANGES.txt

     - "Installation instructions",
       http://zope.org/Products/CMF/CMF-1.5.2/INSTALL.txt

Where do I go to learn more?

     The "CMF mailing list":mailto:zope-cmf@zope.org has many
     participants who are active in supporting the CMF.

...to report bugs?

     The "CMF Collector":http://zope.org/Collectors/CMF
     is ths place to report bugs (please search for existing
     reports of your issue first!)

Did you follow the link and read the description? For one, Blob also  
hooks into the Zope transaction machinery, to maintain transactional  
integrity. I doubt ExtFile does...

Subject: [Zope] [ATTN]: CMF and related packages moved to svn.zope.org
Message-ID: <145E3165-7E21-4D16-873D-0BDB14EC754F@dataflake.org>

Hi everyone,

I just finished migrating the CMF and related projects from  
cvs.zope.org to svn.zope.org, from CVS to Subversion. All tags and  
branches have moved, unlike Zope itself there won't be some  
development using CVS and some using Subversion. These are the packages:

- CMF
- CMF_Hotfixes
- CMF_Extras

They packages became new toplevel projects at svn.zope.org, as can be  
seen here:

   http://svn.zope.org/

Pending final agreement on the CMF list (or an overriding word from  
the CMF Pope himself) svn.zope.org will now be the canonical location  
for CMF sources. They are accessed just like Zope 2.8 and Zope trunk  
as described here:

   http://www.zope.org/DevHome/Subversion/ZopeSVNFAQ

The only difference is, of course, the last element in the path.  
Eveerything else works as described in the document linked above. The  
packages are at...

   /repos/main/[CMF|CMF_Extras|CMF_Hotfixes]

***To all CMF developers***:

Please change your sandboxes and convert them to SVN. If you see any  
problem please make it known on the CMF list as soon as possible. No  
data is lost on cvs.zope.org, so if there are show-stoppers we can  
always switch back to using CVS. Please **do not** commit into  
cvs.zope.org or svn.zope.org until we have a "yay" or "nay" on which  
repository we go forward with.

***Next steps***:

If we have agreement on using svn.zope.org a couple cleanup tasks  
need to be done, such as...

- "Close off" or "freeze" the CMF projects on cvs.zope.org to either  
disallow checkins or bring up big fat warnings if someone tries to.  
Input and ideas on this are welcome, if it was up to me I would use  
the "commitinfo" file in the CVSROOT to completely prevent updates as  
the first step.

- Change any references to cvs.zope.org in the CMF code to their  
svn.zope.org equivalents

- Change any references to cvs.zope.org on the project web pages,  
mostly http://www.zope.org/Products/CMF, to point to the svn.zope.org  
equivalent

- Change any download instructions that use CVS to instructions for SVN

It should be:
product_context = context.manage_addProduct['Photo']
product_context.manage_addPhoto(id=s, ......)

Not so obvious to know :(
You can get hints like this by viewing the source of any ZMI page that
has the Add object drop down.

Using a localization module is common.

Thanks, that works,

but in addition there is an photo.manage_upload(file=img.data) necessary 
too see the images.

Message-ID: <42DC7E22.3040004@earthlink.net>

Hi list,

At times (it seems)  necessary to force a Zope transaction commit.  This 
might occur between two zSQL calls where the second depends on the 
first's *SQL* transaction's availability but the first has not yet been 
commited because the *Zope* transaction that includes both zSQL calls 
has not yet been commited.

I handled this with a call to an external script as below, eg

. zSql1()
. pyCommit() 
zSql2()
Publish new page

Here's pyCommit()

# Extenstion/pyCommit.py
# ...............................................................
from ZODB import FileStorage,DB

def commit( self ):
   t = get_transaction() # ZODB builtin
   if t:
      t.commit()
# ...............................................................

Thats it. And it solved my problem. Is there a reason why this is a bad 
idea, all things being equal?  A better way to do it, when needed?

Thanks,
David

you're playing with fire  ;)

let zope handle the transaction

use <dtml-var sql_delimeter> to separate two or more sql calls

this way, if one of the call fails, the transaction will be aborted

gurus, correct me if i'm wrong, please

Bakhtiar,

Thanks very much for responding.

Your idea is what I thought of at first - but my Interbase Adapter 
doesn't like COMMIT statements (!)  and I didn't test it out.  But it 
seems that would not  solve the problem because both ZSQL methods are 
embedded in the *same* zope transaction stream, e.g.

.  Submit a page
.  call ZSQL1 (part of Zope Tran 100)
. call ZSQL2  (part of Zope Tran 100)  <--- this depends on zSqL1 being 
executed but the transaction has not been executed yet, its pending.
.  Display a page
.  *now* Zope commits (executes all calls - which is too late in this case).

When ZSQL2 is called ZSQL1's results are not yet executed into my RDMS 
and therefore ZSQL2 cannot see whatever ZSQL1 did. (COMMITs not 
with-standing).

Its understandable that Zope might wait between page presentations to 
transact all changes until all succeed ( an exception aborts the 
transaction).  Its just in some cases they can't all succeed until some 
are transacted.

David





(even with your recommended COMMIT) is not available at the time ZSQL2 
is called.

 From what i've seen it appears that Zope commits transactions

It would be better if you explain what you're trying to obtain. Inside a
single *Zope* transaction, all the queries are inside the same *RDBMS*
transaction.

Therefore, the second sql method should see the effects of the first
one. If that is not the case, review what is actually happening (i.e.
the first query may be failing even though you did not detect it).

Regards
Marco

Stop. Should Interbase here behave different? Its actually required
that a database makes changes visible to all queries in the _same
transaction_. It depends on Transaction Isolation Level 
if you see further changes, e.g. if your Database supports "read
committed" - this means you would see data changed by _other
transactions_ that started _after your transaction_.

Thats weird. I'd like to see the model you are referring to here.
Are you perhaps playing with after-commit triggers?

Subject: [Zope] Error in treating custom exception
Message-ID: <42DCBA44.7080902@icube.it>

Hi all.

It looks like I've hit something which is already known (I've found this 
reference:

http://mail.zope.org/pipermail/zope-collector-monitor/2004-October/004316.html

)

I've a custom standard_error_html page, made with a Zope Page Template. 
I'm trying to provide a custom __str__ for a custom exception. This 
works, most of the time, but in some cases I encounter the following error:

TypeError: unbound method __str__() must be called with InvalidFolderId 
instance as first argument (got nothing instead)

InvalidFolderId is the custom exception, of course.

This is the code of the exception:

class InvalidFolderId(Exception):

     def __init__(self, folder_id):
         self.folder_id = folder_id

     def __str__(self):
         return "folder id %s could not be found in the database" % 
self.folder_id


folder_id is a number. What could be done to avoid this problem?

Thank you in advance for the help.

Regards
Marco

Hi

I installed ZPyIRC version 0.1.3 in Zope 2.7.5 and I get Zope  
Template Errors on two of the frames when trying to start a chat  
client. I don't know ZTP very well. (Python is 2.3.5)

I was hoping that maybe somebody has fixed the templates for 2.7.

Any help very welcome!

You could fix the templates yourself or ask the author of the product :-)

2.7.0 is *ancient*. Try 2.7.7.

Stop right here. Zope 2.7.0 is hopelessly outdated. Use Zope 2.7.6.

I use the following template often. When using a page template for my MAIN page, 
I access the error and message vars with:

<p tal:content="options/error">Error message</p>
<p tal:content="options/message">Reg. Message</p>

How would I access them when I use a dtml-method for my MAIN page?
<dtml-var error> and <dtml-var message> don't seem to work.

Python Script - index_html:

# Import a standard function, and get the HTML request and response objects.
from Products.PythonScripts.standard import html_quote
request = container.REQUEST
RESPONSE =  request.RESPONSE

error=''
message=''

if not request.has_key('next_state'):
   return container['MAIN'](context, request, error=error, message=message)

elif  request.get('next_state') == 'Do Something':
   try:
     doSomething()

That _should_ work. 
In DTML, I think when you ask for something it does a options,
REQUEST, context, acquisition context lookup all in one loop. In TAL
you can't be lazy :( and you have to specify exactly where you expect
it to come from.

Bare in mind that keyword arguments only span across ONE template
where as variables in REQUEST span across ALL templates.

Doublecheck your template usage and/or send us your traceback.

I don't get a traceback, i just get error and message back as empty strings; 
their initiallized value.

very strange.

So you're not getting an error. 
What is the initialized value? Is 'error' and 'message' set in REQUEST?
(that you can find out from doing <dtml-var REQUEST>)

I am using DTML only because I am using the excellent Calendar tag product.

sometimes, the links on the calendar tag get affected by from variables so as a 
hack i re-write the QUERY_STRING using:

request.RESPONSE.redirect(request['URL'] + '?mode-calendar=' + 
request['mode-calendar'] + '&date-calendar=' + request['date-calendar'] + 
'&location=' + request['location'])

instead of:

return container['MAIN'](context, request, error=error, message=message)

I originally left that detail out to avoid unnecessary confusion, but I think it 
might be the cause...ideas?

How you get to the page is irrelevant. I don't care if you redirect
there or type in the url or click a link.

Looking at your python script I saw that initially you set error and
message to the empty string ''. I guess the script is not detecting a
'next_state' keyword in the request. So, it is excecuting the first if
of your code:

if not request.has_key('next_state'):
   return container['MAIN'](context, request, error=error, message=message)

Where are you initializing 'next_state'? Try printing the request
object to see if it really exists or perhaps you are doing some typo.

Regards,
Josef

next_state does get initialized - it is the name of the submit buttons on my 
various forms.

Message-ID: <561D4E52-F88C-11D9-8AA1-000A27B3B070@eastlink.ca>

I want to intialize the value of ZTUtils.Iterator and use the value
to increment tabindex attribute  in my ZPT for forms in CMF

Something like:

<div tal:define iterator python:modules['ZTUtils'].Iterator; >
	<div>
		.. html form contents
                    .. a field
                    <input tal:attributes="tabindex 
python:Iterator.next() ...
	         ... etc, etc.	
	</div>
</div>

The first part gives me an iterator object.  How do I get its value as 
an integer?

Subject: [Zope] ZopeProfiler (python profiler) - strange results
Message-ID: <42DD7134.3040406@coig.katowice.pl>

Hi!

I've just run ZopeProfiler few times to check which functions are
slowest in my site and during analysis of the results I've found
something that confuses me a bit.

When I'm showing results using "print_stats" and ordered by "time"
I get times:

calls   tottime      percall   cumtime       percall    function

...    total_x    ...    cumulative_x   ...   X:1026(__call__)


for function X.

This seemed good till I've used "print_callees" format which
showed me that function X is calling function Y and Z and
their execution times are:

functions_time = Y_call_time + Z_call_time.


As far as I understand it "tottime" is the time without
subfunctions' call times and "cumtime" is with subfunctions'
call times, so I supposed that:

cumulative_x - functions_time = total_x

but this is not true... in almost every case I've checked it is
rather:

total_x + functions_time > cumulative_x

Why? I don't think these are concurrent threads...
but what makes this difference? It's possibly
something trivial but... ;)

Don't you need to create it with a sequence like
<div tal:define iterator python:modules['ZTUtils'].Iterator(range(100)); >

Subject: [Zope] performance of textindexng2 vs. zctextindex
Message-ID: <42DD979D.1020301@crubellier.com>

I recently installed TextIndexNG2 2.1.1 on a system running Zope 2.7.6 
on Fedora Core 3. I've been running some comparison tests with 
ZCTextIndex, which is what our site currently uses. We're indexing 
around 50,000 objects at the moment. For TextIndexNG2, this is the 
configuration:

Indexed attributes  	 keywordSearchSource
Default encoding 	utf-8
Storage 	StandardStorage
Stemmer 	english
Splitter: casefolding 	enabled
Splitter: index single characters 	disabled
Splitter: max. length of splitted words 	64
Splitter: separator characters 	.+-_@
Default query parser 	PyQueryParser
Autoexpansion 	disabled
Stopwords 	english
Normalizer 	European
Use converters 	disabled
Near distance 	
Left truncation 	disabled



I've been struck that if the number of search hits is high, TextIndexNG2 
is much slower than ZCTextIndex. For example, if I do a search on 
'podcast' (our site deals w/ podcasting) I get about 14,000 hits. 
ZCTextIndex returns the results in about 0.1 seconds; TextIndexNG2 takes 
31 seconds or 300 times longer. In general, the more hits there are, the 
bigger the difference between the two search indexes.

TextIndexNG2 is great: it has many features that we really want and 
perhaps the cost of those features is performance vis-a-vis ZCTextIndex. 
But I'm hoping that maybe I've overlooked an obvious or not-so-obvious 
configuration issue that will enable me to speed up TextIndexNG2.

Thanks for any advice.

Hi Peter. Thanks for your reply.  I think I am getting closer with this 
but still not quite right.
It appears I am calling Iterator right, because it gets an Iterator 
instance and now getting number 1
but that doesn't tell me much.


<div tal:define = "tabindex python:Iterator(range(100));">

	<div>
		.. html form contents
                    .. a field
                    <input tal:attributes="tabindex/next ...
	         ... another field	
	</div>

is giving tabindex="1" all the way through my forms.  I thought next 
meant next, meaning you are asking the iterator for the next value. 
What am I missing?

Regards,
David

Message-ID: <CDA93487-CEA5-4E17-8BFF-BC753319D9F3@zope.com>

Foundation Update
----------------

This note updates progress on forming of the Zope
Foundation. To remain transparent as possible, we are
communicating in as timely a manner as possible.

First, we have contacted the Software Freedom Law
Center (SFLC) which specializes in the formation and
maintenance of the legal structures that support open
source software. From our first conference call with
our primary POC there (who also helped with the Plone
Foundation), we took away some homework items
including:

    (1) draft trademark license agreement between Zope
        Corporation and the Zope Foundation

    (2) draft/initial set of ByLaws and related formation
        documents that capture the spirit of what we've
        been discussing for a while now (i.e., Eclipse
        Foundation-inspired membership and Apache
        Software Foundation-inspired operations).

We have made progress on (2) but stopped when we
discovered a trademark violation that needs to be
addressed before Zope Corporation can properly license
the trademarks to the Zope Foundation.

During my stay at EuroPython I learned that eighteen
months ago (and without Zope Corporation's knowledge or
consent) Zope Europe Association (ZEA) registered a
trademark consisting of the Cirlce-Z (the stylized Z
surrounded by a circle) followed by the word ZOPE
(hereinafter "Circle-Z-Zope").  The mark they
registered is identical to the corporate logo used by
Zope Corporation.

In the three weeks since learning of ZEA's illegitimate
registration of our marks we have tried diligently (but
unsuccessfully) to get ZEA to unconditionally transfer
the rights of the registration.

We have offered to reimburse the registration fees paid
by the ZEA to the WIPO (World Intellectual Property
Organization) in order to facilitate the transfer. We
have further offered to preserve their license to use
the Zope mark in the conduct of their business as an
association of Zope companies.

ZEA's registration represents an abuse of registration
and management of international trademarks and the
misappropriation of a mark that is clearly the property
of Zope Corporation.  We are sorely disappointed that
ZEA is unwilling to transfer the marks quickly and
quietly so that we can proceed swiftly toward the
formation of the Zope Foundation.

We know that the establishment of a fair trademark
license for the entire Zope community is an _essential_
component of the Zope Foundation. It is possible that
we will come to a conclusion with the ZEA prior to the
conclusion of a trademark dispute process.

However, as a result (and unfortunately), until this
matter is resolved using the established
legal/trademark management processes, we are not able
to proceed with the Zope Foundation. We will keep the
community updated as milestones are reached, so that
you know what the new target dates are for the
formation of the Foundation at the same time that we
do.

We recognize that there are lingering questions about
the trademark and our management thereof.  We have
captured our position on these marks in an open letter
to the Zope Community.  You can find this letter at:

o http://www.zope.com/about_us/legal/ 
ZopeCorpTrademarkManagement_OpenLetter.html

As an aside, the ZEA has also registered the Plone logo
as a trademark.  It is not our business, but came as a
surprise to us, that the Plone Foundation is not the
owner of the Plone trademark.

Query speed depends on different things: the query, the implementation, the 
operations needed to be performed during the query. Because of some 
functionality TXNG needs to store much more information than ZCTextIndex.
It did this as said above sometimes in a not so efficient way (see above).
You might also look at TextIndexNG V3.

Isn't this really strange? How can ZEA register any ZC trademark?!
Either ZC is the owner of the trademarks including Europe or it isn't?!
So either ZEA is violating the ZC trademark rights knowingly or ZC maybe 
never had any registered trademarks in Europe....you someone please clarify 
this (Paul?).

Huh?! What exactly is the problems with the MIT license? It's prettymuch 
the simplest and least restrictive open source license out there, which 
is why I selected it. Did you actually read the license file? ;-)

The MIT license has NOTHING to do with the GPL.

Subject: [Zope] should stream iterator be used for ZODB-generated string
	file?
Message-ID: <dbl4uc$jl1$1@sea.gmane.org>

We have an application whereby multimegabyte strings, each generated 
from the contents of several thousands of small objects in ZODB, are 
downloaded from zope as a CSV files. A particular CSV file is typically 
downloaded once or twice a day at a maximum.

The major issue is that it takes a long time for the download to start. 
Would it be possible to use a stream iterator (introduced in zope 2.7.1) 
or should we simply do chunks of REQUEST.write() ? What are the 
requirements for using chunked REQUEST.write - do some specific HTTP 
headers need to be set or does zope take care of it all?

Any advice or specific pointers would be appreciated. I've googled all I 
could find about the stream iterators, serving blobs etc. but all the 
info seems to be focused on serving large filesystem-based data. I am 
not sure what parts of that info applies to an use case that involves 
reading data from ZODB, or if stream iterators make sense for the use 
case at all.

I guess we could generate a temporary file and then serve that using a 
stream iterator. I understand some parts of the zope machinery could 
perhaps be released faster that way, but I wonder if the benefits are 
worth the extra step.

Thanks!

Pre-amble: I post this as a principal in a decently-sized Zope-focused
business in the UK. Our company is also partnering with ZEA for some
work. I will try to correct some of Rob's factual errors, and set the
record straight for some of the issues discussed here.

I am not an official spokesperson of ZEA, though - so bear in mind
that what I'm saying here reflects what *I* (and my company) think
about the situation, and not what ZEA thinks. I know a bit about why
the decision to register the trademarks in Europe was made, why the
managing partners of ZEA authorised it, and what's going on on the
other side of the fence. I am reasonably neutral, though - and care
more about what happens to Zope the *community* than anything else.

This is wrong. ZEA offered you to transfer the trademarks if you
covered the expenses involved in the registration (including the
salary of the trademark professionals involved in the registration
process), no strings attached - but Zope Corporation declined, and was
more interested in sending threatening letters about trademark abuse,
even though ZEA is the rightful owner of these marks in Europe at the
moment. They were more interested in having the matter resolved
*their* way than to cover the actual costs involved in registering the
trademarks from ZEA's side.

Aidan McGuire of Blue Fountain (another UK zope company), Xavier Heymans 
(of ZEA) and myself had a conference call with Lois Snitkoff from ZC on 
the 12th of July in which we offered to transfer the trademark if ZC 
contribute to the fees of the registration and, in the unwillingness to 
transfer the trademark to the ZF, at least agree to some form of 'social 
contract' that states the uses and rights of the mark.  After consulting 
with others within ZC Lois' reply stated:

"Just to let you know quickly, we will not be paying any of the
costs incurred when you registered our trademark. I have checked
with management and they reiterate what our position has been
consistently."

Which directly contradicts what is said above.

The registrations were not illegitimate, the Zope trademark was not
registered anywhere but in the US at this point, so it was done as a
defensive move to make sure the trademark was in friendly hands. In
Europe you have companies/trademarks like ZOPEN that could have been
problematic for the registration and approval, so a decision was made
early on to secure the trademark for the Zope *community*.

The companies that constitute ZEA make up a large part of the
professional Zope companies in Europe, and they have a lot to lose by
the brand being insecure in Europe.

And in what way does not accepting ZEA's offer, to transfer the
trademark to you by covering the costs involved in the registration,
constitute "try diligently"?

So why is Zope Foundation being used as a pawn in the corporate
strategies of Zope Corporation? I find this unclear intent pretty
disconcerting.

So why are you unwilling to put the Zope trademark under the ownership
of Zope *Foundation*? Again, Zope Foundation is being used as a pawn
in the company strategies of Zope Corporation.

Not true. ZEA's trademark experts helped Plone Foundation register the
Plone trademark initially, and promptly transferred the ownership of
the trademarks to the Plone Foundation, just as they are willing to do
the same for Zope Foundation.

Personally, I find it interesting that Zope Corporation insists on
ownership of the trademark instead of putting it in the Foundation.
The moment Zope Corporation goes bankrupt, any company can buy the
remnants and name their interesting Java/.NET technology "Zope", and
use the brand recognition to their advantage.

Additionally, Zope Corporation is free to grant a company *exclusive*
usage of the trademark "Zope" in any country. Say, for example that
they decided to partner with a UK company to provide Zope services in
the UK - that company could be granted exclusive rights to use the
trademark Zope in that country, which I'm sure a lot of companies
would have an issue with. After all, they have spent all this time
building the brand of a competitor. This is very unfair to the
companies that have spent time and effort building the Zope brand -
which should be collectively owned by the community - hence Zope
Foundation.

If your trademark protection is supposed to make any sense, Zope
*Foundation* should have ownership of the trademark - not Zope
Corporation. ZEA at this moment represents more of the Zope community
than Zope Corporation does.

I find it a sad state of affairs when Zope Corporation has to resort
to these tactics instead of seeking an amiable resolution to the
matters when a solution is available.

Subject: [Zope] ZCTextIndex - Collector Item #505?
References: <20050720061916.3729.qmail@web51110.mail.yahoo.com>
Message-ID: <001d01c58d22$6c2dea00$677ba8c0@amd>

I have encountered an unusual situation which I believe may be related to 
collector item #505  (http://www.zope.org/Collectors/Zope/505 - ZCTextUndex 
should not hold a reference to a lexicon).

Prior to performing a ZCatalog update I cleared the catalog (using the clear 
catalog option under the Advanced tab of the ZMI); then, to clear out the 
Lexicon, I deleted the Lexicon and created a new Lexicon (id of both was 
'Lexicon').

I then added about 805,000 records to the ZCatalog (which went smoothly) and 
tested catalog searches - all went well, including globbing searches, 'and', 
'and not' searches.

The previous Lexicon had 764,410 word entries.  The current Lexicon has 0 
word entries.

The ZCatalog and ZCTextIndex appear to be working ok, so I am guessing that 
somehow the ZCTextIndex is using a 'hidden/old' version of the Lexicon (not 
the newly created version) - which is very strange, as the .fs file was 
packed prior to the update (so any old versions should have been deleted).

This activity was all performed on a linux server running zope 2.6.1

Finally, the questions:

1) Can ZCTextIndex really be using the some other version of the Lexicon 
(which I can not access via the ZMI)?
2) Was Collector Item #505 ever fixed (I can not find a reference to issue 
#505 in any of the zope change logs)?

Thanks,

Jonathan

Why did not ZEA came up with such arguments against the ZF *much earlier*?
The ZF proposal is out since some weeks. There was meanwhile an IRC chat 
with Rob,  a lengthy discussion on the mailing list and Rob spoke at 
Europython. I can not remember having heard any objections from ZEA against 
this proposal. I have not heard any public statements of Paul Everitt at 
Europython during the ZF presentation *against* the ZF.

Speaking as independent developer - neither representing the interests of 
ZC nor of ZEA - I find these behind-the-curtain negotiations extremely 
counterproductive from the community point of view and definitely not in 
the sense of the Zope community.

Hi Chris. Thanks for your reply.

My understanding (which may be flawed) is that ZTUtils iterator 
provides values of a sequence as you iterate over them with a repeat 
statement.  I believe what I am trying to do is sensible.  I have 
looked at the api and can't seem to get the right magic using the 
methods  provided.  Tabindex for forms keeps track of tab position so 
when you use tab key it moves the cursor to next field tabindex in form 
.  So if I have 5 input fields from top to bottom, I want to define an 
iterator object, and obtain the next number in the iterator when zpt 
does its thing to create the form so that I would have a tabindex 
starting at 1 and next field value would be 2, then 3 etc.

A range by itself doesn't do the trick since it provides all values to 
the variable where I am looking only for a single number incremented to 
the next value.

Regards,
David

- From $ZOPE/lib/python/ZTUtils/Iterator:

 __doc__='''Iterator class

 Unlike the builtin iterators of Python 2.2+, these classes are
 designed to maintain information about the state of an iteration.
 The Iterator() function accepts either a sequence or a Python
 iterator.  The next() method fetches the next item, and returns
 true if it succeeds.

Note that last sentence, which explains why you are seeing the '1' value
everywere.  'tal:repeat' over a range should get you what you want;  I
don't think you *need* an iterator for your use case.

I believe you can restrict the host(s) the emergency user's
credentials are valid from.  This will only happen if you specify it,
though, and you can always change the emergency user data (username,
password, and host restrictions) by editing the 'access' file in the
zope instance.

Speaking for me, I felt asking this type of questions suspecting ZC to 
found ZF for its own sake would not have helped.

Having a Foundation is a major step if we can manage to have it built 
community-oriented.

If you remember well, I did ask some questions about the tone of the IRC 
chat which I did not feel as an opened discussion : rather I felt it as 
a suite of questions/answers about things that were presented like facts.

I had the feeling that my reaction was already misunderstood my some of 
the attendants. So I did not even think of speaking of the trademark 
question... which had striked me as one of the critical points : IIRC, 
the TM was the first thing mentioned in ZC longer explanation.

There is nothing against the ZF : there is sthing against ZC being the 
sole owner of the TMs when the current value of it has been established 
by the community as a whole, especially out of USA.

This is why I support the proposal made by a few members of the 
community to have the ZF own the TMs and that would give a perpetual 
license to Zope Corporation to use it.

For instance,

"""...it would be far better for everyone if Zope Corporation were 
instead to transfer the trademark to the foundation and receive a 
perpetual/irrevocable/etc. license back."""

It's definitely better to speak about it in the open air, where we all 
will be able to think about it together.

Thanks Tres.  The 1's are explained for sure but I can't see a always 
doing the job for this.  What I need is an object that keeps track of 
the last number given to it so it will supply the next based on its 
state.  For use in a flat form with say a dozen fields you are not 
repeating over each field but still you need an incrementing tabindex 
value. In this case no repeat is necessary but each call to tabindex 
still requires next value and you can't do this if there if state is 
not available. I thought I could use the built-in iterator in this way 
but 1 or 0 for next will not return what I need from the instance.  
Could a method be added to existing Iterator class to provide the 
current or next value of Iterator instance for this purpose as opposed 
to true and false. Maybe called them currval and nextval or similar. I 
hoping not to have to create a product just to do this.

Regards
David

Amen.

I wasn't aware of this until ten minutes ago, and now it seems a whole
bunch of stuff has gone on, up to and including people getting shirty
with each other, which I would have liked to have known about earlier.

I'm an independent developer and I'm pretty quiet in the community, but
I've pretty much bet my livelihood on Zope - this stuff /matters/ to me!

What makes me unhappy about this is people making sweeping and
inaccurate statements which also imply bad faith. The idea that an
organisation that only registered a trademark in one territory describes
the registration of the same mark in a /different/ territory as a
"violation" is very irksome because it ignores the nature of trademark
law (in which context ZC not registering it in Europe is negligence,
plain and simple, if they want to pursue it), but infinitely more
irksome is the implication that this was somehow done in bad faith, when
what little I know about it indicates the exact opposite.

This has the potential to make the Zope community look like muppets, and
not in a good "Swedish chef" kind of way...

At the Zope Europe Association Web site
(http://www.zope-europe.org/), the logo is 3 cubes with a
3-dimensional look.  Has Zope Europe Association registered the
Circle-Z-Zope trademark but is not using it?  Or is there another
Zope Europe Association?  Or, have they registered it for future
use?  Or, if you can register a trademark in different countries,
have they registered it so as to protect it from miss-use by
someone else?

Yes, it can.  The ZCTextIndex holds an attribute, 'index', which is an
instance of either OkapiIndex or CosineIndex.  That subobject also holds
a reference to the lexicon, which is the reason for the collector follow-up:

 Partial fix in place. I still need to resolve the deeper reference held
 in the actual index object that ZCTextIndex delegates to (more fun and
 games)

No, it has not been fixed.  The workaround in your case is to delete the
entire ZCTextIndex, re-add it, and re-index your content.  You might be
able to revivify the current lexicon by opening the database yourself,
but the risk / reward ratio is pretty steep, compared to just recreating
the index.

Thanks for the info Tres.

For now I will leave the ZCatalog/ZCTextIndex as-is (I don't really need to 
access the Lexicon via the ZMI - it is just nice to check how many entries 
the indexing process has created), and will 'delete/re-create' the Lexicon 
AND the ZCTextIndex during next months update cycle.

Thanks again,

Jonathan

I'm not sure muppetism applies to the Zope community, it appears to be 
Zope Corporation who are coming out of this looking less than clever.

It's a shame, because really, they should be the ones benefitting from 
the community they've created, but instead they're more and more 
isolating themselves from a community which is finally starting to 
realise that Zope's continued popularity is not predicated on the 
survival of Zope Corporation.

I hope Lois in particular reads this and understands that you can't 
bully an open source community, and doing so is likely going have much 
worse consequences for the bully in the medium to long term than it will 
for the people being bullied.

cheers,

Chris

Agreed/understood - but ZC are part of the community, too - the BDFL

Well, ZC are becoming less benign and more dictatorial, and that's where

This is beyond my understanding. ZC created Zope. ZC created the brand.
ZC is called "Zope Corp". Why on earth would they relinquish the core
asset that is their trademark and branding? It's theirs. They're giving
the full use of it to the community. What's wrong with that? Why do you
want, require, more?

The current state of what ZC proposes doesn't prevent anyone from doing
anything reasonable.

You may need to set the Content-Length yourself, if you want it.
Otherwise REQUEST.write is pretty simple to use.
The only thing is that it ties up a Zope thread during the output.

It would still take time to generate the temporary file, though.

If you do it properly you end up handing off the file to the asyncore
machinery which frees your Zope threads to do other more intersting
things than serving bytes.

Question re v 2.2.0:  on this page 
http://www.zope.org/Members/ajung/TextIndexNG there are three 
possibilities 2.2.0, 2.2.0b1, 2.2.0b2. The last modified column 
indicates that 2.2.0 has been modified most recently, but I'm assuming 
that the b1 & b2 versions are in fact more recent. Is that true?

Also, 2.2.0b1 is around 2MB, whereas the other two are 600K and I 
noticed after downloading 2.2.0 that stemming support seems absent.

So, from all this I'm assuming that if I want stemming support I should 
grab the 2MB 2.2.0b1. Is that right?

I'll look into StupidStorage.

V3 is appealing but we're running 2.7.6 and I'm not sure that I want the 
hassle of installing Five at this point. When we go to 2.8, which we'll 
probably due in a couple of months, V3 will be an option.

Thanks for your help,

Why should beta versions be more recent than the final version? 2.2.0 is 
the latest.

This is documented in the release notes. 2.2.0 does not support stemming 
anymore.

Subject: [Zope] More TM ideas
Message-ID: <3FA2E3EA-F225-4821-9FFF-8C1873BA76A9@zope.com>

Following up to my note from yesterday.

ZEA *is* the official registrant (but not legitimate
owner) of the Cirlce-Z-Zope (CZZ) mark in many
countries in the Madrid Protocol.  You can search the
WIPO database for "Zope" and find it.

Zope Corporation is the official registrant of the word
Zope in many countries in the Madrid Protocol and our
registration predates the ZEAs.  Since the ZEA
registration is based on the word Zope we believe that
an official trademark opposition will be successful.

We are also only willing to pay the fees that Zope
Corporation would otherwise have had to pay to register
the marks itself.  This offer was made in writing last
Friday.

The subtle but important point is that ZEA seems to be
willing to transfer the marks to the Zope Foundation
not Zope Corporation.  This seems to be the essence of
the difference in our position.  If this is inaccurate
-- i.e., ZEA is willing to transfer the marks to ZC
with no strings attached then we can chalk this up to
some incredible communication issue and can certainly
move forward!

It seems that the prospect of Zope Corporation's unfair
(and unprecedented) management of the marks is the real
issue.

So that our position and policy are clear:

   ***

   We will not use (nor allow our successors or assigns)
   to use the Zope trademarks in non-competitive ways.

   ***

The challenge is to figure out how to get this in
place.

One idea might be to make the BoD of the Zope
Foundation the arbiter of any revocation action ZC
might take.  This would be a contractual relationship
between ZC (and its successors and assigns) and the ZF.
If ZC felt that a given ZC-licensed use of the marks
had become inappropriate we would move to revoke the
trademark license.  If the license holder was
unsatisfied with the revocation they would appeal to
the Zope Foundation which, on vote of a supermajority
of the BoD could overrule ZC's revocation action.

It is our heartfelt sense that Zope Corporation is more
likely to defend (within guidelines and process) the
marks than a volunteer-led Foundation.  We have heard
comments that suggest that the Foundation should not be
in the business of enforcement.  Enforcement is an
active responsibility.  Perhaps once (and while) ZF has
full-time staff to pursue Foundation business
(including TM matters) the Foundation would be the
first stop for tm issues.

It has been reported that ZEA's original registration
of the marks was defensive and done in an effort to
preclude registrations from being made by unfriendly
parties.  We find it simply surprising that the first
mention of their registrations to us was 18 months (!)
after the fact.

ZEA does not represent the entire Zope community in
Europe (nor do they claim to) and certainly don't
represent the global Zope community.  In fact, we
should all recognize that the ZEA competes with non-ZEA
companies on proposals.  That's fine, expected and
natural.  However, any action on ZEA's part that was
made on "behalf of the community" is inappropriate.

ZC does not claim to represent the whole Zope Community
either.  We are asserting our ownership (and, we think)
aggressive desire to manage the marks and brand in a
vendor-neutral way.

With respect to ZEA's ownership of the Plone trademark
- I am told by two people that ZEA helped register the
Plone mark as a service to the Plone Foundation and
that it has been or is in the process of being
transferred. Presuming this is true I stand corrected.
Even this morning the WIPO database advertises ZEA as
the registrant of record for the mark.

Regards,
Rob

Apparently. Go to:

   http://www.wipo.int/ipdl/en/search/madrid/search-struct.jsp

and enter "Zope" in the "Holder Name" field and click "Search".

You will see 5 results.  The first is for the Zope Corporation
registration of the name "Zope", registered in May 2004.

The next four results are for ZEA's registrations of the Zope
and Plone marks, with logos (2 each, for different sets of
countries) registered in July and September of 2004.

You have three alternatives (perhaps four if you consider linux):

First alternative:
1.1 Install the python 2.3.4 binaries (the python that comes with zope,
     isn't logged on the registry, so, you can't use it)
1.2 Install the the egenix binaries
1.3 Copy the egenix installed files to:
      C:\YourZopeFolder\lib\python
      If I'm not wrong, the binaries are installed on :
      C:\python2.3\lib\python2.1 -> Make sure that you don't overwrite
      something in the zope's python. You can download the source code
      of egenix to have an idea of the files it installs
1.4 Uninstall python if you want

Second alternative:
2.1 Create a folder called Python in C:\
2.2 Create manualy this registry key:
      [HKEY_LOCAL_MACHINE\SOFTWARE\Python\PythonCore\2.3\InstallPath]
2.3 Set its value to C:\Python
2.4 Install the egenix binaries (they will be installed somewhere on
     C:\Python).
2.5 Copy the egenix installed files to:
      C:\YourZopeFolder\lib\python
2.6 Delete the registry key

Alternatively to step 2.2, you can get this registry file:
http://www.zope.org/Members/SmileyChris/HowTo.2005-02-06.0339/pil_for_windows_fakepython.reg
Before double clicking on it, change the 2.1 by 2.3 in your
preffered text editor. Then you can double click on it and it will
automatically install the key. Be aware that the key will remain on
the registry till you manually delete it.


Third alternative: Install python from source and then egenix. Here
you need a C compiler. Finally copy the egenix files to
C:\YourZopeFolder\lib\python

I hope this was usefull. I did alternative 2 once and it worked. I
haven't tested it recently, so, I can't guarantee it.

Josef

Hi Erik,

So, then it should be in the request object. Just to test it, put the
following at the begining of your python script (You don't have to
delelete anything):

return request

Then submit the form that calls the script and check if next_state is
really a key in the request object. On the contrary, it could be an
error in the html code where create the form.

This has to be one of the more ill-informed, offensive posts
that I have seen from a member of the Zope community, and
that's saying a lot.

It's obvious that there's a good ventriloquist pulling
Chris' strings, since he's making assertions that are so
easily proven incorrect that they are laughable.

Yes, of course, we are looking less than clever. We offer up
a Foundation. We give all of our ZPL copyrighted code to
this Foundation. We give committers free membership and an
equal number of board seats to vendors who pay for those
board seats. Somehow, we're "bad guys" in this.

I agree. Trying to work with some of the people in this
community make me personally feel less than clever...

ZEA takes marks _directly from our website_, registers them
as their own, and they are "white knights". You're a genius.

See above. More and more we are isolating ourselves, by
joining sprints internationally, contributing our code to a
Foundation that _we_ are bringing to the community, and by
offering to participate completely in the ECM project as
well. I can see how this is isolationist. Again, you're a
genius.

And now, for the ultimate in idiocy.

Lois has not _once_ communicated directly with the
"community" on anything other than announcements regarding
training. Certainly, she has never "bullied" the community
on any topic, including the Foundation.

So, how do I know you are being manipulated into making
stupid public statements? Someone obviously had to tell you
that Lois was involved in the ZEA discussions. Want to know
how? Probably not, since you were stupid enough to parrot
someone else's words, but for the benefit of everyone else
who has a brain, and cares to really understand the truth,
here goes:

Rob and I had the only interactions with any ZEA members,
and they were _exclusively_ with Xavier Heymans and Paul
Everitt. After one exchange with Paul, he requested to be
let out of the continued discussions due to potential
conflicts of interest (which we respected).

Lois received an email out of the clear blue from another
ZEA member (who had not been on any of the emails between
Rob, Paul, Xavier and myself). He reached out to Lois asking
her to participate in a conference call with him, another
ZEA member (also not on any previous communications) and
Xavier. Rob and I were not invited to participate in this
call.

Lois was _not_ in the loop on our side either previous to
this attempt to reach out to her. The three ZEA members
discussed the issue with Lois for 70 minutes. I doubt they
reached out to her because they thought she was the "bully"
in our bunch.

At the end of the conversation, Lois came to Rob and I and
supported some of the requests that ZEA made in terms of
compensation for the transfer. The amount that was
originally requested (20,000 EUROS, plus additional
"transfer fees") was absurd to me, and even though Lois was
willing to find a middle ground, she was the "messenger"
that related to them that "management" rejected their offer.

Three days later, Lois wrote back a note to Xavier (this
past Friday), again playing the messenger, with a offer to
pay any expenses that we otherwise would have had to pay to
be the original registrars of the marks. It is my contention
that if someone steals something from you, you shouldn't
have to pay them a premium to get it back, should you?

We have had no response to that note, and we informed them
more than a week in advance that we would make this matter
public if they didn't respond. Obviously, they didn't mind
it being made public, or they would have found a way to work
it out.

Now, let's continue with the history lesson, this time
concentrating on me, rather than Lois.

I invested in Zope Corporation (then Digital Creations) in
October 1998. I was the largest investor (using my personal
money) then, and through two additional rounds of funding
remain the largest single personal investor (by a long
shot!). So, my money is where my mouth is in this company.

It was _me_, and me alone that suggested in November of 1998
that we open source the software (before it was even called
Zope).

It was me that discussed the licensing issues with Bruce
Perens to come up with ZPL 1.0. It was me who discussed the
licensing issues with Richard Stallman to come up with ZPL
2.0 which was also GPL compatible (which ZPL 1.0 was not).

I participated personally in the numerous hours on the phone
last year (yes, last year!) with our attorneys to discuss
what the steps were in forming a Zope Foundation. When Zope
3 was finally ready for prime time, at the request of Rob
Page, I fully supported kicking off the process of launching
the Foundation, and giving over all of the copyrighted ZPL
code to it.

For those who don't know me, I'm the greedy VC in this
bullying company who has been so abusive to the community.
It's obvious that I (and by extension) Zope Corp are out to
get all of you...

The bottom line is that I have been supportive of the
community from the minute it was formed, and have never done
anything to hurt the community in any action since then (7
years is not a short track record!). To be accused of
anything nefarious or "bullying" is simply a personal
affront. To accuse Lois is simply ignorant, since she
doesn't deal with the community at all.

It is people like you, and posts like this, that make me
wonder whether the economic risks of starting a Foundation,
donating our copyrighted code to it, and licensing our marks
to it on an irrevocable basis are worth the trouble.
Obviously you don't think so. Perhaps, we could work
something out by paying everyone in the community $100,000
per year to download Zope and use it. Would that work for
you personally?

The only reason that I won't consider not continuing with
the Foundation is that like in everything else in the world,
I honestly believe that there is a true _silent majority_ in
the Zope Community. Hard-working honest people who don't
think that Zope Corp is "out to get them", who appreciate
most of what we've done _for_ and _with_ the community, but
are too busy leading their lives to chime in and publicly
support our various efforts. It would be a double outrage to
hurt those people in any way, just to spite an idiot like
you.

So, I won't, and you too will benefit from our largesse. Too
bad...

Hi All,

I'm having a rather strange problem.

I'm trying to get the Issue Dealer
(http://www.nidelven-it.no/products/issue_dealer) product up-and-running
on my Zope install (FreeBSD 4.11, Zope 2.7.1, Python 2.3.4). According
to the Issue Dealer docs, I should simply be able to unzip it into the
Products directory, restart Zope, and go, just like normal.

I've done this, however, and nothing happens. Issue Dealer doesn't show
up in /Control_Panel/Products, or the [Add] dropdown. No broken
products, no nothing.

Nothing looks at all unusual in the Products directory on the file
system.

I've tried rebooting the machine and restarting from the ZMI, to no
avail.

Has anyone seen this before? Any ideas?

Thanks,
Aaron

Make sure that you have a '__init__.py' file in the top level directory of 
the Issue Dealer subdirectory tree, and also check to see if there are any 
messages in the log file (.../zope/var/logger.log or something similar).

Indeed. I don't have any problem with ZC keeping the trademarks, but why 
are they tying the creation of the foundation onto their retreival of 
their lost marks?

The two seem totally unconnected to me...

Considering that we have agreed to license our marks to the
Foundation, and that the lawyers tell us that this is the
first step, we have to have _clear title_ to them in order
to have a valid license agreement.

If there's an ongoing trademark dispute, then we can't
cleanly license the marks to the Foundation. It seemed
obvious to us in our post that we were explaining this, but
it must not have been clear enough. Is it clear now?

My read on this is that there is a serious communication problem going
on here between the lines. Why doesn't Paul come out and state what the
ZEA position is? Why are ZC's words so angry?

ZC saying the marks were stolen seems a little over the top. What if ZEA
registered them defensively? if that's possible then ZEA should be given
then  benefit of the doubt and not be called a thief. If there was a
need to register them to protect "zope", then why didn't ZC do it?

Everybody needs to calm down, stop insulting each other and stop
broadcasting this problem to the whole world on zope-announce (for
example). Its making us all look  childish.

Making either side into the bad guy is not only innacurate but also
inappropriate and is not conducive to building a community around the
software we all love and are grateful to ZC and non-ZC related
programmers alike for, Zope.

+1. Please folks, remember that this is a public venue and your
words will be archived for a long time. Let's have no more name-calling, and
no more mysterious digs at named and unnamed third parties.

FWIW, I think the Foundation is an important and commendable initiative,
and I think ZC has been doing a pretty good job of supporting and reaching
out
to the community lately. And now more than ever, the amount of software that
we get free (and Free) from ZC is just staggering. The trademark issue is an
unfortunate, if unignorable, distraction from the progress that's being made.
I remain hopeful that an amicable solution is forthcoming.

I am disappointed hearing that ZEA registered the trademarks silently 
already 18 months ago. The German Zope User Group (DZUG) asked ZC for 
permission using the Zope logo and the domain name zope.de for our 
community websites (which was never a problem). But in this case we would 
have to ask ZEA for permission as keeper of the trademarks in Europe?! I am 
sorry to say this but the secrecy on the ZEA side is not really acceptable. 
I can understand ZEA argument to have registered the trademarks for 
defending Zope from improper use but why did not you notify ZC or the 
community about it? As someone working in the Zope business I need to know 
who is having what and why. Such things should not kept secret when you are 
dealing in the open-source business. So this whole issue is a shame for the 
complete Zope community.

I am a casual watcher of what happens in the Zope community (I only 
check the development things actively).
However I believe that I knew that ZE did register the Zope logo.
(All tough "instinctively" I would have to have gone to ZC to ask for 
permission to use it should the need have presented itself).
So I do not believe it really was a secret, neither is it a cause for 
disappointment. Somebody had to do it and sometimes you just have to 
move forward. This is fine with me  if you do so as a "good" community 
member trying to secure things without going into to much of the legal 
paperwork that is sure to erupt when you deal in such affairs with an US 
company.

It is the handling of affairs that is .. what should I say .. fascinating.

Somehow I have the impression that we had similar exchanges on these 
canals amongst the same performers before.
Seems that being a good person does not necessarily mean you are a nice one.

If it wasn't a secret I am sure that ZC would know about the secret. At 
least after the announcement for the ZF I would have expected that someone 
from the ZEA would have set: well, the ZF is fine but there is a problem 
with transfering the right to the ZF because *we* have the trademarks 
registered in Europe :-)

Subject: [Zope] css in filesystem based product
Message-ID: <20050721065702.86744.qmail@web25603.mail.ukl.yahoo.com>

Hi *, I'm having issues developing a filesystem based product.
The product loads correctly and I see my zpt, but I'm not able to apply a stylesheet.
The product directory is under Zope-Instance/Products, I've created some directories where I put styles and templates - but changing this structure is no problem at all.
I don't have the slightest idea on how I can hook the .css to the .zpt, probably the css must be "published" inside zope in some ways, but I don't know how.
I'm using plain Zope, no Plone and no CMF. I've also tried to look how Plone does this but without any success (it's just too big ...).
 
TIA,
  ngw

Just pretend it's a DTML file..

from Globals import DTMLFile

cssName = DTMLFile('relative/path/main.css', globals())

name your file 'main.css.dtml'

then you can use;

<link rel="StyleSheet" href="cssName" type="text/css" />

+1 this is also my understanding judging from the messages flowing
around. 

The statement of ZC indicates they want to transfer their trademark
to ZF and now find the european trademark in other hands. OTOH, why
not just transfer/licence what they have (the .us trademark) and
just agree to ZEA transfer/licence the european trademark to ZF
too? 

As I understand, the benefit of a ZF with the source in the hand 
would be to help contributors to defend against patent issues
which you probably cant avoid if you do any development.
So I really like to see ZF founded as soon as possible.

So please ZC and ZEA come together, the community really wants
it. 

May I suggest to create a temp not-public-archived mailinglist
to further discuss this issue?

Subject: [Zope] product beginer question : how to code add_xx_form and
 manage_add_xx such that xx finds instance of another product yy
Message-ID: <42DF5D91.1000005@free.fr>

Hi

sorry for the logn subjet :)

I'm using Zope 2.7.5-final, python 2.3.5, linux2, and I'm just strating
to code my first products.

Here's my problem: I want to make a product that watchs instances from
other products.

for instance, let's say I have a product yy, with its add_yy_Form,
manage_add_yy and class yy definitions, such that instances of yy just
display memorised a string.

now I want to build product xx such that when I create an instance of
xx, I can tell it, throug the form provided by add_xx_form, which
instance of yy I want it to watch at. (let's say for instance I want
instance form yy to display the reverse of the chosen instance from xx)

so I need add_yy_form to provide the end user with some kind of select
from instances at hand (in current page, or in current page plus
subpages would be nicer) and then I need the manage_add_yy to process
that and be able to find the reference of the selected zope object.

I thought of one solution : to provide a select with the url of the objects.

So here come the questions :
 - is that ok, or is there a better way ?
 - is 'absolute_url()' the simplest way to find the urls for add_yy_form
 - if I manage to find a reference back from the url in manage_add_yy,
   what will happend if someone moves the object around, using
   copy/cut/paste for instance ? will what I think of as a reference
   still be pointing to the correct item ?

(Note that my solution must not be specific to instances of xx : yy
shall be able to watch instances from any kind of product)


(sorry for such a simple question with such a long introduction... )

thanks!

Ah, I see what you're after, something akin to an SQL sequence, right?
Well, Iterator ain't that ;-)

What's so horrible about just putting these tabindexes in by hand?

Your code would certainly execture faster...

Any clues are appreciated,

This is not a Zope issue. It's an error from your SMTP server. I can't
explain why or how an SMTP server works but I've had problems like
this before because the SMTP tried to prevent spam relaying.
Secondly, does the weird error message (with the empty curly brackets)
imply that the recipient is null? ie. empty string or None
Perhaps ZEPP has a bug that it tries to send an email even if the
address is blank.

zlib? Did your zope work fine before? 
Remember, about 2 weeks ago they found a vunorability in zlib, didn't
they. Maybe there are some implications into that on openbsd.

Well, --- it doesn't sound likely, because it's not only with zlib. I 
just got this one:

I restart Zope and all is well. I'm running Zope 2.7.6-final by the way.
Perhaps I should upgrade to 2.7.7. Hopefully this is solved with 2.8.0, 
but it looks like the next compatible Plone release is some way ahead 
still.

How about ditching OpenBSD and installing a streamline linux like
debian instead?
There seems to be a problem with your python, not Zope. Zope just
happens to manage to stresstest your python binaries.
(I'm not saying linux is better than bsd, but it appears that python
works better on linux for serious applications)

No, just the opposite.  ZC do *not* want to transfer the marks to the 
ZF.  I do find this position strange.  Whilst they are willing to 
transfer all the IP, for which yes we are grateful.  The issue being 
that many companies around the world are investing marketing money and 
time in developing and promoting the 'zope brand'.  The problem is that 
this brand now (since ZC renamed from DC) also co-incides with Zope 
Corporation.  The value of this brand is increasing and needs to be 
protected, hence why the marks have been trademarked in the other 
companies in which ZC did not register.  I am guessing that ZC 
registered the marks in the countries that are most commercially 
valuable to them -- an understandable move as it was their bucks paying 
for it.  However the *zope community* extends beyond these countries and 
needs protection too.

The main conflict arises because:

* The zope community and Zope Corporation use the same word 'zope'
   to identify themselves.
* ZC don't want to let go of their trademarked name as that is a
   major asset to their business.
* Many people in the zope community feel uneasy that a corporation
   which can be bought and sold owns the name of the software that
   they are developing.

All these points are perfectly valid and understandable, but what we 
need to work out is a way in which we can try and combine and merge 
these conflicting points in a sane way.

I personally (remember, these views are all mine) welcome Rob's ideas on 
how to ensure that ZC's potential successors or assigns use the Zope 
trademark in a fair way.  The problem being, I don't see how that can 
happen if the trademarks are owned by ZC as if the company were bought 
it would be up to the new owned what would happen with its own property. 
  Yes we could put a contract in place between ZF and ZC to say that ZF 
can be the arbiter of any disputes, but I don't see how that can remain 
in place if ZC changes hands.

Malthe,
   What architecture are you running OpenBSD on?  We have been running 
Zope on OpenBSD/AMD64 3.6 for about a year now and it works pretty well. 
  I have however recently discovered a python bug that I am trying to 
track down.  I am unsure of the exact problem, but it affects the re and 
string libs:

zeo1# uname -a
OpenBSD zeo1.netsight.co.uk 3.6 conf#0 amd64
zeo1# python
Python 2.3.4 (#1, Nov 16 2004, 08:26:06)
[GCC 3.3.2 (propolice)] on openbsd3
Type "help", "copyright", "credits" or "license" for more information.
 >>> import string
 >>> string.whitespace
'\t\n\x0b\x0c\r \x89\x8a\x8b\x8c\x8d\xa0'

on all other platforms I've tried string.whitespace stops after '\r'... 
the trailing chars cause problems in weird and wonderful places.  I 
upgraded to python 2.3.5 and get the same result.  Not tried on python 
2.4 yet.

Other than that, we've not had any memory issues.  On OpenBSD a single 
process cannot grow over 1GB of process memory (it can get more than 
that via anon-mmap, but python doesn't support that).  On OpenBSD 3.5 we 
notice that if we hit the 1GB barrier hard it would panic the kernel, 
but that was fixed in 3.6.

How much memory is python using when you get the memory errors?  Has it 
truely used up all the memory on the system?  There are soft limits that 
are set via login.conf and ulimit/limits which may be too low for you.

-Matt

Hi

I have a question about my new plone site.

How I can configure apache or zope to access to my old webmail (php
aplication) under my new plone domain.

I using zope and plone with apache server (with ProxyPass option)

My new site is http://www.gualeguaychu.gov.ar

I want to access to my old website under
http://www.gualeguaychu.gov.ar/mail, but it would have to leave the
plone site and access with apache to my old php webmail and this not
works (I have the  "404 Not Found" message).

Excuse my poor english and thanls in advance.

Subject: [Zope] Running more than one instance on windows often block each
	other
Message-ID: <dbo06u$8ee$1@sea.gmane.org>

Hi list,

I run a few zope instances on a windows machine 
(xp). I start them either with runzope.bat or as 
services. The behaviour below is independent of this.

But sometimes a running instance (A) seems to 
block another instance (B) from starting. This 
does not happen every time.

If I stop instance A and start B again, it runs 
fine. The funny thing is that sometimes B starts 
fine even with a running A. (Or vice versa).

Of course I set them to run on different port 
numbers in zope.conf. (HTTP, FTP etc.)

I can see (with the excellent (and free) 'Process 
Explorer' from sysinternals) that the python 
processes always opens port 19999, and connects by 
that port to themselves on another port (for 
instance 2550).

Maybe my problem has something to do with this?

Has anybody experienced the same behaviour?

greetings,
Sune

We're running a dual-cpu system:

According to 'top', the total load is:

* Memory: 80M/131M act/tot  Free: 366M  Swap: 0K/1028M used/tot,

where Zope itself is using practically all of it.

Theo might be listening --- I'd rather not. OpenBSD is a great platform, 
and if there's music to be faced, OpenBSD will surely face it. But if these 
errors persist, I might have too.

Well the question is, should Zope be using all that memory?  how big is 
the site, what are you doing, how big are your caches etc?  Our zope 
processes normally run about 500 - 750MB so maybe you just don't have 
enough memory.

But odd that no swap is being used in your case.  I would check your 
per-process memory limits maybe they need to be higher.  Our 'zope' 
account is in login class 'daemon' which has higher default memory 
limits than 'standard'.  And even then we bumped the limits up even higher.

I've found OpenBSD/AMD64 and Zope to be an excellent platform.  As I say 
I just need to track down this bug in python that has just become 
apparent (we have been running for almost a year without hitting it, so 
not too serious).

The Opteron 244 (1.8Ghz) is about 20% or so faster on pystone than a 
3Ghz Xeon, not very scientific test or relevent to real life, but a good 
guide).  Especially interesting considering you can buy 2.8Ghz Opterons 
right now.

I'm not too impressed with our system's performance, but I haven't profiled 
our site yet or set up a proper proxy. The system is always very responsive 
in the shell, so I think that Zope might use the disks too excessively.

Our site isn't especially large or complex (http://nanotek.nano.ku.dk). We

I'd like to try and set up Zope in another login-class. It seems correct, 
as there are soft limits on memory usage in the default class. How would I 
go about this? Do you use a custom zopectl or run it straight off inetd?

You need to have a zope user (adduser) and put that in the deamon class 
when it asks you.  If you already has the user then you can change the 
class with 'chpass zopeuser'.  Then you need to edit /etc/login.conf to 
raise the limits of deamon if you need to, and run cap_mkdb if you use 
databse versions of the login.conf file.

Zopectl doesn't need to change.  Just remember to set the effective-user 
to zopeuser in zope.conf

Well, that wasn't very helpful afterall. It already was in login-class 
'daemon'. However, I did try and boost the stack size for that class from 
8MB to 32MB. We'll see how that works out.

I am amazed at how people pick and choose what to read and
repeat, and what to ignore. I will mix in a few quotes from
a few posts responding to my note yesterday to highlight
this problem.

After this post, unless someone makes a profound new
statement, I will remain silent, as many of you have
requested, and complete the trademark challenge process
through the official channels that have already begun.

George, others have already replied to this, but Rob has
written about this as well before, so I'm surprised that
this is still a question. A defensive registration of _our_
trademark should have been _explicitly_ called to our
attention. In fact, any reasonable company would have
alerted us to any specific danger, and asked us if _we_
intended to register our trademarks in the appropriate
jurisdiction.

Beyond that point, _we_ are the first registrants of the
ZOPE trademark in WIPO. ZEA registered our LOGO, not the
word ZOPE, which we registered _before_ they registered the
LOGO. So, everyone, please pay attention. We did _not_
ignore our trademark rights in Europe. We registered our
base trademark, the word ZOPE, in a number of countries in
Europe. ZEA then registered our LOGO (taken from our
website), including the name ZOPE in it (which we had
already registered).

I am truly unsure as to how to make this point any clearer.

There isn't really a communication problem here (though it
would wonderful if there was). There is a backtracking and a
rewriting of history going on, because ZEA got caught with
their hands in our cookie jar. They could have settled this
incredibly quietly and quickly. Instead, they chose a path
that has led us here.

We could have fought it silently too, so it's 100% true that
we are the ones that brought this fight into the public. On
the other hand, I can't imagine what would have happened if
this private battle dragged on until January, and then we
got beaten up for missing the launch date on the Foundation,
and only then alerted the community as to what was going on.

So, we did what we thought was the most prudent thing, and
alerted the community 2 days after we initiated the
challenge to their registration. I don't know how we could
have been more transparent about it.

Read the above response again (and again if necessary). More
importantly, ask yourself why ZEA admitted to us during a
phone call that they believe that there were deals that they
could not have won if they didn't control the mark? Now
extend that thought one more inch and ask yourself how the
Zope-based companies that they competed against in Europe
would feel if they knew that this was a commercial leverage
point for ZEA in winning against their bid?!?!?

And again, read the above to see that our registration of the
mark "ZOPE" predates theirs.

Indeed, we do look childish, and I'm perhaps _more_ to blame
for that escalation than others. That's why I will try to
keep this as my last communication (at least for a while) on
this topic. That said, a number of people responded saying
that they were not only glad to be made aware of this
problem, but were surprised that they didn't know about it
sooner.

The rhetoric (mine as well!) is louder than it should be,
but I believe the issue(s) definitely needed to be aired, as
it's utterly obvious that even the more basic of the "facts"
are still misunderstood by a number of posters. As an
example, the repeated questioning of why we didn't register
our own marks in Europe, which we did.

Please don't say that things are "innacurate" when you
aren't involved, and have already repeated a number of
"innacuracies" yourself, which were readily available for
you to check before you repeated them...

This is correct. We are transferring IP, and not the
trademarks. Are we allowed to keep anything, or should we
donate all of our programmers to the Foundation, but keep
paying their salaries as well? Just tell us what will make
100% of the people in the community love us, and we'll
consider it...

Amazingly enough, we have owned the trademark since 2002 (we
changed our name in 2001, and it took that long to get the
trademark registered in the US). There was _no_ hope of a
Foundation at the time. Yet, by your own admission, you and
others continued to invest marketing money in the brand.
Why?

The more amazing part is that now that we will transfer the
IP to the Foundation, and give an _irrevocable_ license to
the Foundation for the use of the word ZOPE to brand the
software (which can _never_ be taken back, even if someone
acquires us), but somehow, _now_ you are worried about
investing in the Zope brand. I simply can't connect the
dots.

Two months ago, you would invest, when there was no
Foundation on the horizon, and the Zope software could be
revoked by a future acquirer of ZC. Now, there will be a
guaranteed future for the Zope software and brand forever,
independent of ZC, but that's somehow now "risky" for you to
invest...

True. We're not the only ones. MySQL, JBOSS, etc.

True. However, it is _nothing_ like what is being described
by people who think we're being bad (you included). We want
to make sure that when something has the word Zope in it,
that it can't _mistakenly_ give the impression that it is a
product of Zope Corporation. PERIOD. Trademark is purely a
_sourcing_ issue. If the use of the word Zope does not
connote Zope Corporation, then we have no problem with it
(and never have had).

Rob gave a number of examples in his follow up yesterday.
I'll repeat one of them since it seems that repetition is
more necessary than I would have thought. Egenix uses the
word Zope _directly_ in one of their product names:

eGenix mxODBC Zope DA

They asked (as a result of some of these public TM
discussions) whether they needed a license from us or not.
We immediately informed them that they did not require a
license, even though the word Zope was in their product
name!

Do you get it now? No consumer could have been confused that
this was a product of Zope Corporation. Therefore, we assert
_no control_ over the word Zope in that regard.

> * Many people in the zope community feel uneasy that a

Agreed, but again, it is truly just paranoia (see above).
Worse, it can only get better after the Foundation has feel
and clear (and eternal) use of the mark to brand the
software "Zope", but somehow, it's now a bigger issue than
it has been in years...

At the moment, there's nothing to work out. We will prevail
in our challenge to ZEA's filing, and everything will then
continue on course. This can be accelerated if ZEA
voluntarily gives up their registration (or transfers it to
us, etc.).

Our TM is our asset. We don't intend to give it away. We
don't intend to give our building away either. Perhaps the
community wishes to chip in (or perhaps just ZEA) and wants
to make an offer to ZC to purchase the TM for themselves or
on behalf of the Foundation. All reasonable offers will be
considered :-)

I agree that Rob's suggestion was a good one, and the fact
that I agreed to it shows that we are more than willing to
work with the community to find _reasonable_ ways to solve
problems.

Perhaps European law is different that US law, but Rob
stated clearly that the contract would name ZC's successors
and assigns, which makes it legally binding on anyone who
purchases ZC as well. In the US, that contract would survive
the sale of ZC. I see no reason to be paranoid about that
eventuality, as long as you would trust the initial contract
between ZC and the ZF.

To repeat myself (yet again), this is my last post unless
someone makes a truly new point.

Hi Chris

I guess something like that but that is what an iterator does.  ZTUtils 
just doesn't provide a method to get the values out of it (which it 
could if the methods were available).

> What's so horrible about just putting these tabindexes in by hand?

Well, by hand is not the solution either.  It is not as simple as that 
since I am using portlets in CMF and there are forms in portlets too.  
You can't just number them like 1,2,3 etc because you end up with 
conflicts in tabindex values when your templates are rendered.  This is 
the second problem I am trying to solve because ZTUtils allow you to 
pass into it whatever sequence you want.  You could give it a different 
sequence to start with so when it iterates using its own sequence, 
results keeps the tabindex from conflicting.  This is more of a case of 
looking at an existing tool to perform this so you can retrieve from 
your ZPT (that doesn't require you to write one with all the security 
bypasses to make it work).  It appears ZTUtils is the tool that could 
do this.  I mean it is an object, it iterates, it iterates on values 
you pass it , it knows its current state and the security has been 
bypassed to let you call it in a ZPT, it just doesn't provide a method 
to obtain its values directly.

David

Python version won't matter:  the value of string.whitespace is
entirely determined by your platform C and the locale in effect when
the C-coded portion of Python's string module (Modules/stropmodule.c)
is imported.  As you can see from that module's initstrop() function,
string.whitespace consists exactly of the 8-bit characters (0-255) for
which the platform C's isspace() macro returns a true value.  The
results you've seen on most systems:

    '\t\n\x0b\x0c\r '

is what it must be in the "C" locale (the C standard defines this),
but if you're not in the "C" locale it could be anything.

It's not unusual (well, not for non-Americans <wink>) to see \xa0 in
that list, because \xa0 is Latin-1's non-breaking space character
("&nbsp;" in HTML).  It's surprising to me to see \x89-\x8d there,
though.  It could be your system is set to use "an unusual" locale, or
it could be a bug in the platform C libraries.  Try writing a little C
program to see what isspace() returns.

hi,

i need to store some data as long as the user is logged on to zope.
how can i achieve this?

using the session is not a good idea, because some parts of the code 
simply call session.clear()  (i did not write that part).

if everything fails, i can use a singleton where i put a dictionary 
based on some-kind-of user-id... but i'd like to avoid that if possible 
(don't want to think about the multi-user-asking-at-the-same-time

is there any place where i could attach my data structure?

Session is still the best thing you can use in this case.
Note that HTTP is stateless, you just dont know when
a user "logs out". - unless she is so friendly to use
a button on your site where you can trigger to delete
the session and auth cookie.

yes, i know that the session is stateless..

it's just that there IS an authentication at the beginning...
the standard login/password thing...
(i just recently came to the codebase). so ZOPE know when the user logs 
in and when he logs out.
and i'd like to somehow use that information to store my data somewhere.

A few points I want to clear up... the next two paragraphs I write are 
about technicalities, I am not refering to any moral right or wrong, or 
who did what etc.

In my view the confusion is apparent.  If I go to zope.org I see the 
same logo (admittedly with the word community added to it).  If I 
install Zope and go to the ZMI one of the first things I see is the Zope 
logo.  I can clearly see how people associate the logo with the 
software.  Very few clients (and potential clients) we talk to in the UK 
are even aware of ZC... *in their mind* Zope is a CMS not a company.

And please please please remember that there is no such thing as 
'registered the trademark in Europe'.  There are many companies in 
Europe and the trademarks have to be registered in specific countries.

You are twisting the truth here -- I wish I had recorded the phone call 
now to prevent the chinese whispers :)  On the call to Lois, Xavier said 
that there are certain possibilities of using Zope for EU projects which 
would be hampered by a corporation (ie ZC) owning the trademark to the 
OSS software.  ZEA does not want the trademark.  Repeat.  ZEA does not 
want the trademark.

Yes, you are still mis-understanding the facts.  Europe consists of many 
countries, of which you registered the mark in just six - Germany, 
Denmark, Spain, France, Great Britain and Italy.

ZEA then went on to further protect the mark registering it in: Austria, 
Bulgaria, Switzerland, Cyrus, Czech Republic, Hungary, Lithuania, 
Poland, Portugal, Romania, Russia, Slovenia, Slovakia, Ukraine

Because we believed (and still want to believe) in the good of all the 
parties involved.  I guess when we started investing in promoting the 
software there was no confusion with the name, now there is.

I guess its because IANAL, but I just:

1) Don't understand how an irrevocable license works.
2) Am still unclear of licencing issues, when Rob spoke at EPC about the 
foundation it was very unclear as to who would make decisions on 
licensing, in some cases ZC would have the final say, and in some cases 
the ZF.  It just seemed confusing to me.
3) ZC is a very small, yet very powerful part of the Zope Community 
(maybe this is just my view from Europe).  Can you explain to me exactly 
what benefits ZC has in holding the trademarks as opposed to them being 
held by an independant foundation?  The fact that ZC doesn't want them 
to be held by an independant 3rd party makes me think something sinister 
is planned on the horizon.

Yes a future acquirer of ZC could try and revoke the software, but it is 
licensed under the ZPL so is joint ownership.  I think this creates 
enough of an incentive to prevent this happening as much of the code is 
contributed by people other than ZC.

Yes, it is reasonable and it is a start of dialogue.  This is a distinct 
improvement over last week's approach of 'We are not negotiating 
anything.  Hand it over or we set our lawyers on you'.  When I 
*specifically* asked Lois if something like this was possible she 
re-iterated that you would not be willing to enter any further discussion.

OK, in which case, that makes sense to me.  Combined with Rob's idea of 
letting the board of the ZF make the decisions on licensing issues I 
think I personally am happy.

Thankfully i'm not directly involved in these pointless  internecine
battles between ZC and one of its founders, but I am involved in the zope
community and ZC brought this issue into the community so i am involved
as is everyone else here. You don't get to make the issue public and
then tell people they aren't involved.

According to rob page's post of yesterday, Zope registered the word
"Zope" while ZEA registered the Zope logo. So when i ask why didn't ZC
register the marks earlier, i am clearly not repeating an innaccuracy,
unless you are saying that rob page's post to zope announce was innacurate.

I'm not sure if I know what I'm talking about, but.....

It seams to me that when I was reading up on the session thingy,
I read that you can add new Seesion thingy to the Zope tree thereby
creating your own private session...

Of course I'm Probably wrong....

you could store the data in a cookie on the user's pc, or create a 
dictionary and store it in a temp_folder (stored in ram, not persistant). 
The dictionary would only work if you had a reliable way to identify a 
returning user (ie. do they log in with an ID that you could use as the 
dictionary key?).

in python you can continue a logical line over several physical lines by 
placing a '\' character in the last position of the line you want continued.

Why don't you use ZSQL methods?

Bingo! Thanks for the hints.

You were correct, it was down to a mis-interpretation of the C99 and ISO 
8859 standards.  Looks like OpenBSD interprets it differently to 
everything else ;)

The policy was changed 8 days ago:

http://www.openbsd.org/cgi-bin/cvsweb/src/lib/libc/gen/ctype_.c

Python allows you to you triple-quotes to include line breaks in the
string::

  sql="""DELETE FROM tblUsers
         WHERE user_name LIKE '%'"""

Matt, unfrotuntately (for me), you make a number of very
good points, so I will break my self-imposed silence to
respond ;-)

Unfortunately for everyone else, this continues the thread,
but at least it feels to me like we're "de-escalating" and
hopefully actually getting somewhere good, faster...

You are absolutely correct. In certain usages, we try to
make the distinction obvious (like Community being part of
the logo, and certainly in adding "Corporation" in our own
logo). That said, our "Logo Usage" page on zope.com, which
has been there for a _very_ long time, makes it clear that
we own the trademark for _all_ variations of the mark, and
that we _freely_ license it (without any signatures!) for
certain usage, and license it under a contract for all other
usages (most of those are free too!):

http://www.zope.com/about_us/legal/zope_logo_usage.html

The point is that even the logo in the free Zope software is
"owned" by us. It just happens to be freely licensed, with
no fee or contract. That doesn't make it available to be
registered as an owned trademark by someone else.

We don't care if potential clients of yours don't associate
the logo with us, that's obviously fine. We _do_ care if
they associate the logo with ZEA and nobody else. If they
associate it with Zope the software, that's fine too, and
doesn't require a license, but that still leaves us as the
owners of the mark.

Again, you are correct. I noted in my previous response to

Huh? ZEA does not represent everyone in the Zope Community
(as Rob has already pointed out) and worse, does not even
represent all commercial Zope companies in Europe. How does
ZEA holding the trademark make an EU project "less hampered"
than ZC holding it? You can keep repeating that ZEA doesn't
want the trademark, and yet, you registered it...

Really? We registered the base word Zope, from which all of
our other marks derive (except for the separate trademark
that we have on the Circle-Z logo). You did _not_ register
the word Zope in any of the other countries, so you did not
in fact "further protect the mark" in the countries that you
mention above. You registered a logo that we have a
registered trademark for in the US, that we paid to design,
that includes our registered (in a number of EU countries as
well) trademark "ZOPE", with publicly stated policies for
its usage available on our website, and not only registered
it in the "additional" countries, but also registered it in
all of the countries where we were already "protected".

I truly think it's time to just call it like it is, and stop
pretending that you were saving the world from a few bad
guys.

People make mistakes, we all do. We didn't threaten to sue
you (though we were most definitely accused of having
threatened to sue you, which we responded to in writing that
we did _not_ intend to sue you!). We simply pointed out that
the mark was registered in your name, and that we wanted it
transferred back to us. At this point, the transfer would
still solve the problem quickly, but we are just as happy to
have it "reversed", which in some sense will more firmly
cement that our position was correct all along...

My point is that the confusion has existed since 2001. This is 4
years later, and you continue to invest. It's obvious (to me) that
we haven't behaved in any way that should cause people to stop
investing in the brand, and that we continue to try to be creative
in finding ways to make people feel even more comfortable in
continuing that investment (like Rob's recent suggestion of having
the ZF be the ultimate arbiter).

Straight from the dictionary:

http://dictionary.reference.com/search?q=irrevocable

"Impossible to retract or revoke: an irrevocable decision."

Note the word "Impossible" in the definition...

We have attempted to clarify that in writing in Rob's post on Tuesday.
The Foundation will be responsible (100%) for any licensing involving
the Software, and ZC will not be involved. For any "business" use of
the word Zope, ZC will be involved if there is any ambiguity regarding
whether the business use implies ZC.

Sinister? We want two things from holding the trademark:

1) No confusion as to the source of our products.

2) The right to license the mark to those that see value in it.

Since the rights that 99.9% of the community are interested in are covered
100% by the license to the ZF, there should be a handful of people 
world-wide
who will be unhappy with this (if everyone truly understands the issue), and
those people are unhappy today anyway, since we already own the mark.

We are talking apples and oranges here. You could always fork the
software. Before the ZF though, your fork would have had to be renamed
and the brand equity you so desire would be gone in an instant. With the
new ZF, and our irrevocable license to it, no acquirer can _ever_ take back
the word Zope from the community (or more properly from the ZF). This
is _way_ better than the situation you are currently in, but somehow, the
TM debate rages on.

Let's make another important distinction here. We were not,
and are not willing to negotiate with ZEA over the
registration of our TM.

We are _more_ than willing, and have _always_ been willing
to listen to the community regarding issues that can help
the community grow. So, when the current TM dispute is
behind us, and it is obvious to one and all that we own the
TM wherever we choose to register it, we will be happy to
continue to find even more ways to make the community feel
comfortable regarding TM and anything else, for the growth
of the community, and the benefit of all.

Excellent! Like I said in my first post yesterday, even with
the current dispute ongoing, it is our intention to fulfill
every promise we have made with regard to forming the
Foundation and delivering the code and the license for the
marks. The only thing we said was there might be a delay in
the formation, until the dispute is resolved.

Perhaps, since you are a member of the ZEA, you can help
make some of your other members more comfortable, and help
accelerate the resolution of the dispute. If not, that's
fine too.

I agree with Andreas. ZSQLs are a good thing. If you mix python code
and sql code you're likely to run into problems sooner or later.
Bare in mind that ZSQLs aren't just a method to store the sql
statement, they also have caching and other nifty functions such as
parameter handling.

Let me guess... you write your HTML in python code strings? :)

I bumped up the stacksize to 32MB, i.e. in /etc/login.conf:

daemon:\
        :ignorenologin:\
        :datasize=infinity:\
        :maxproc=infinity:\
        :openfiles-cur=128:\
        :stacksize-cur=32M:\
        :localcipher=blowfish,8:\
        :tc=default:

This seems to have done the trick. At least I haven't experienced any 
errors during the last couple of hours, and everything seems quite healthy.

I'll follow up if it turns out to be a fluke.

Sorry, not unless someone can give useful information.  If you're

doesn't work, and tell us the solution.  If you're not familiar with
Python, it will have to wait until someone who is familiar, and can

Sorry, I thought that was clear. It says exactly the same as the ZOPE 
error message:

U:\>U:\programme\Zope-2.8.0\bin\python.exe
Python 2.3.5 (#62, Feb  8 2005, 16:23:02) [MSC v.1200 32 bit (Intel)] on

 >>> from ZConfig.components.logger import loghandler
Traceback (most recent call last):
   File "<stdin>", line 1, in ?
ImportError: No module named components.logger
 >>>

But I think I found the error: On Windows, Python seems to prefer 
information from the Registry to the environment vars. The wrong 
registry information was left there from a prior Zope/Plone 
installation. It seems the Zope-2.8.0 Windows installer does not update 
the registry for Python, so Python takes a wrong import path. I found 
out by saying
   import ZConfig
   globals()
and the wrong directory would show up. Removing the old installation 
solved the problem. Other Zope installations (2.7.4, 2.7.6) were not 
affected by the left-over registry entries. So I suppose this is a 
subtle bug in the 2.8.0 Windows installer.

The emergency user account will not work.  I have tried deleting and

Could that be hanging it up?

No. The LDAPUserFolder does not interfere with emergency user handling.

Subject: [Zope] FSZSQLMethod.py refactory
Message-ID: <42E00C53.6050103@yahoo.com.br>

Hi,

I did a refactory in the FSZSQLMethod.py module of CMFCore from SVN. I 
want to use my ZSQLs from the filesystem and I improved the module to 
better support to this feature.

Can someone commit this patch to the CMFCore SVN?

Now, the sintax to the FS ZSQLs is:

##title=My query
##connection_id=DataBase
##arguments=arg1 arg2 arg3
##max_rows=1000
##max_cache=100
##cache_time=0
select * from table

For each file with .zsql extension. Only connection_id is required. The 
same pattern of FSPythonScript.

Sorry for the attachment, the CMF SVN does't work at this moment, to 
promote my diff!

Regards!

Thank you -- that way we don't have to guess about anything.  I note
there that you did _not_ run Python while in Zope's bin\ directory,
but instead ran it while in the root of your U: disk.  That differs
from what I did, and may be significant (although I doubt it, the
current directory does play a role in setting up sys.path).

> But I think I found the error: On Windows, Python seems to prefer
> information from the Registry to the environment vars.

No, despite popular myth, Python on Windows normally doesn't consult
the registry for anything.  The exception is obscure "application
paths", never used in core Python, described in the near-inscrutable
comment block at top of this:

   http://cvs.sf.net/viewcvs.py/python/python/dist/src/PC/getpathp.c?rev=1.

Unfortunately, older (than build 204) versions of the pywin32 (aka
win32all) extensions did set "application paths" in the registry, and
Zope used to go on to install pywin32 in a broken way, causing no end
of potential PYTHONPATH confusions.  The Zope Windows installer does
not (and never did) set "application paths" in this sense.

Do recall exactly which registry keys seemed to be significant?

As above.

Since Python doesn't normally consult the registry to build sys.path,
I don't think the problem is understood yet.

I'm not clear on what you did here.  Earlier you showed that you were
unable to import ZConfig.components.logger.  But you _were_ able to
import ZConfig on its own?

That's good -- I think <wink>.

Which registry entries, specifically?

The Zope Windows installer installs pywin32 in a very different way
than it used to, and installs a very different version of pywin32 than
it used to, but the zope.iss.in files (which are the input Inno Setup
uses to build the installer, and which contain the code for setting
Zope's registry entries) are byte-for-byte identical across 2.7 and
2.8.

First of all, CMF-related items are better discussed on the zope- 
cmf@zope.org list.

Can you explain how your changes "better support" ZSQL methods on the  
file system? They work perfectly fine the way they are.

Oh, and what exactly is not working about the CMF Subversion repository?

The HTML is imbalanced. HTMLTidy may help you, or maybe an editor, but 
you can always count the tags by hand.

runzope or zopectl fg 
are good for testing if the installation works
because you get all the messages on screen (like you show below)

zopectl start 

should be used in production because it detaches zope 
from the shell. I think the INSTALL.txt section
needs some clarify on this - although zopectl
gets mentioned there:

"""
Starting Zope

  Once an instance home has been created, the Zope server can now be
  started using this command:

    /location/of/zope/instance/bin/runzope

  If you get errors indicating that addresses are in use, then you
  will have to supply arguments to runzope to change the ports used
  for HTTP or FTP. The default HTTP and FTP ports used by Zope are
  8080 and 8021 respectively. You can change the ports used by
  specifying the "port-base" parameter to runzope.  For example, to
  run Zope on ports 9080 and 9021::

    ./bin/runzope -X port-base=1000

  There is also an interactive Zope command shell named 'zopectl' that
  may be invoked by running 'bin/zopectl'.  By default, 'zopectl
  start' will start a background process that manages Zope and
  'zopectl stop' will stop the background process.

this is faszinating. I have no Idea why on your installation
are the docstrings None. 

Yan you please quote the code lines around line 236 in 
/Programs/Zope/2.7.6/lib/python/Products/ZCatalog/IZCatalog.py 
?

It was. no candy. It did buy some time though, so there might be a real

Message-ID: <5775AF95424CB249882242ADC57A910B1306C1@ibmbxnorte.intranet.ibermatica>

Hello all,

I apologize if this is a wrong list for the question, but the
python-crypto list doesn't seem to be working (at least I haven't
received anything from there, not even the mails I've sent). Anyway I
suppose there are people here who run the ZServerSSL with Zope.

We're having some problems downloading large files from Zope/Plone
running
on win32, through an SSL connection. Uploads seem work ok.

There's been some discussion about similar issues, but with uploads
(http://www.zope.org/Wikis/DevSite/Proposals/ZServerSSLIntegration).
The variable ac_out_buffer_size in https_server.py mentioned in that
post
is not present in the current version (or at least I haven't found it).
The ac_in_buffer_size is assigned a value of 32k (1 << 16 bit shift
operation). We've tried to change this value but with no success.

This seems to be a problem only with SSL connections. If we download the
same file (say, for example of 200MB) through HTTP connection the file
transfers correctly. The same transfer through an SSL connection
produces
a corrupted file.

M2Crypto 0.13 (suppose, The ZServerSSL has been installed with the
Windows
installer), Plone 2.0.3, Zope 2.7.0, Python 2.3.3 on win32.

Kind regards,

Tuukka

Subject: [Zope] manage_changeProperties quirk?
Message-ID: <fd56d20d6cc92ef9c53564dae5494abf@yahoo.co.uk>

Hiya,

I had a strange problem today, on a Zope 2.5 installation (yes, it will 
be upgraded soon...). Basically, I've got a form action which calls 
manage_changeProperties() on a number of subfolders using

<dtml-call expr="folder_place.manage_changeProperties(order=number)">

Now, this works absolutely fine throughout my installation, but in one 
instance it was raising an Unauthorized Error for all users, no matter 
what their permissions/roles:

> Site Error
>
> An error was encountered while publishing this resource.
>
> Unauthorized
> You are not authorized to access manage_changeProperties.

So I tried pretty much everything - checking all sorts of permissions 
and other stuff, but eventually made a copy of the folder, to make sure 
it wasn't something peculiar with the folder name - the copy worked 
perfectly. So, I then replaced the original folder with the folder copy 
and this worked fine too.

So, basically, problem solved. But I'm now concerned - could this 
happen again? Is there something I'm missing? Has anyone experienced 
something like this before?

Cheers,

JB

Shot in the dark: Was this folder created (and thus under effective  
ownership) of a user that has been deleted from the user folder?

Yep. Exactly - I hadn't thought of that, but yes, it was created by 
someone who's now left. Deeply impressive.

Thanks Jens.

Message-ID: <Pine.GSO.4.58.0507220908370.29318@lapis.engin.umich.edu>

My current Zope setup uses SSL and FastCGI. For some reason,
<dtml-sendmail> is no longer working for me. The error I get is the
following:

Exception Type	gaierror
Exception Value	(7, 'No address associated with nodename')

I have confirmed the name of our mail server with IT staff so the problem
is not in the nodename but for some reason the name is not being mapped to
the correct address. Is this because of FastCGI? Has anyone experienced
something similar?

If this continues to be a problem, what are my other options?

Any help would be greatly appreciated. Thanks.

Sorry!

The actual implemantation parsing a code with 
<dtml-comment></dtml-comment> tags in its body, with the arguments list. 
I think it's ugly.

"""
# parse parameters
parameters={}
start = data.find('<dtml-comment>')
end   = data.find('</dtml-comment>')
if start==-1 or end==-1 or start>end:
     raise ValueError,'Could not find parameter block'
block = data[start+14:end]
"""

So, the entire data information is submited in template, or either, the 
body of zsql method receives <dtml-comment> tags and the arguments list 
too. I don't know how can it work!?

"""
self.manage_edit(title, connection_id, arguments, template=data)
"""

In the top of template has a comment:

"""
(not yet) Customizable ZSQL methods that come from the filesystem.
"""

I think (not yet) means this module is not working yet, and it is my 
impression after my tests and analisys the code!

I am using Plone 2.1, following the instruction:

http://plone.org/development/info/participation

It worked fine 2 days ago, but now it give me a timeout exception.

Forgives myself for trying to help the community!

Subject: [Zope] object acquisition via python scripts
Message-ID: <ECOWS03MniiLkZfJuEN0011c00b@smtp-out3.blueyonder.co.uk>

Hi,

 

I'm not sure if the subject line accurately describes what I'm trying to do,
anyway let me try and explain.

 

I have a set of folders like this:

 

Site root object

      |---- Attributes object

      |---- Layout ZPT

      |---- get_attobject (python script)

      |---- get_attributes (python script)

      |---- Folder object A

                  |-----Attributes object

      |---- Folder object B

 

 

My 'get_attobject' script is called from my 'Layout zpt' using this code:

<div tal:define="attobject here/get_attobject"></div>

 

And my get_attobject script contains the following code:

 

      attobjects = context.objectValues('Attributes object')

      if attobjects:

            return attobjects[0]

      return None

            

Then my get_attributes script uses the attobjects value returned from the
get_attobject script to output the values of the 'Attributes object'. Now
this all works fine in the 'Site root object' and in 'Folder object A' but
when I get to 'Folder object B' there is nothing returned since I have no
'Attributes object' present. 

 

But what I'd like to do in this situation is use acquisition to retrieve the
values from the parent 'Attributes object' located in the site root. So
could someone please explain how I could achieve this?

 

Hope someone can help me, many thanks. If any more information is required
please ask.

 

Jon

As you've discovered, objectValues() does not use acquisition, it
only looks for real sub-objects of the folder you call it on.
Same is true for objectItems() and objectIds().

This kind of thing is typically done by always using the same id for
your "attributes object". Then just acquire that id.
In a sense, the id becomes part of your API.

Your script would become:
 
attrobject = getattr(context, 'some_id', None)
return attrobject

Looking up your attributes object through objectValues will prevent
acquisition - rather than just asking the object to find an attributes
object for you, you're asking it for any attributes object amongst its
children only.

To search for your attributes object with acquisition, you could do:

getattr(context, 'Attributes object')

If the id of your attributes object did not contain a space (or anything
else illegal in a python identifier), for example AttributesObject, you
could just do:

context.AttributesObject

Thanks,
Malcolm.

Subject: [Zope] Zope trademark - ZEA point of view
Message-ID: <416E8B86-282A-42E2-9EF7-A0DC04BFE52F@zope-europe.org>

This email is an answer to the questions raised by Rob Page in his  
email titled ?Zope Foundation update?. It was posted on zope.org  
mailing list, Tuesday July 19, 2005. This document also tries to  
answer questions raised on the mailing list.

Later in the document:
Zope Corporation = ZC
Zope Europe Association = ZEA

About ZEA
ZEA goals are to promote and develop the Zope technology. The  
association currently regroups 16 businesses from 9 countries, which  
are actively involved in the creation or promotion of the technology.  
As a non-profit, we are developing contact with users, private and  
public entities. Part of our focus is to provide an increased  
visibility of the Zope ecosystem.

ZEA management is independent of the business interest. Paul and  
Xavier roles are to focus on commons issues. Due to a conflict of  
interest, Paul has not been involved in ZEA decision to register the  
trademark.

A ? Zope trademark  : situation and facts

1/ Europython, June 29, 2005
I took the initiative to set-up a face-to-face meeting with Rob.  
During a 2 hours conversation, I presented ZEA goals, activities and  
their positive impact on Zope internationally.  I explained that  
working on the Plone trademark, I found out that Zope trademark  
wasn?t protected and explained the reasons of the decision to  
register the mark. In his email on zope.org, Rob forgot to mention  
that ZEA openly provided these informations to ZC.

2/ Reasons for registering the Zope trademark - 2003Q4
At the end of 2003, there was unrest within the Community related to  
the trademark. ZC made clear statement that the trademark was  
protected, while it was not. Unknown entities had taken actions to  
register it in some countries. The decision of a defensive  
registration was taken among ZEA partners. The goal was to freeze the  
situation, with an agreement that ZEA wasn?t the right entity to hold  
the trademark in the long-term. The registration process started on  
January 5, 2004. Both our trademark expert and legal adviser agree  
that these registrations are not illegal as suggested by ZC.

3/ Trademark registration
A trademark has to be registered and its status carefully followed.  
The underlying issues and risk can hardly be summarized in a few  
lines. ZEA has been advised by a trademark expert in the steps to  
follow. To reduce the risk of opposition by third parties, her advice  
was to register a ?figurative trademark? = the mark and its logo, and  
not to advertise the process.
For transparency, I accept to show evidences of the process to the  
Zope Community and if necessary organize a meeting with Dominique,  
the trademark expert (file about 100 pages). On July 12, during a  
mediation attempt, I made the same offer to ZC. My proposition was  
rejected.

4/ Why Plone is currently under the name of ZEA?
The Plone registration started before the Plone Foundation (PF)  
creation. The work was done on behalf of representatives of the Plone  
Community. The final transfer should be done by Q3Q42005, we are  
currently expecting documentation from the registration office. The  
PF is aware of the process.
Having informed Rob about my involvement in the process (point1), I  
was surprised that he came up with this point on a Zope mailing list  
rather than contacting directly the PF. In the case of the PF, this  
situation didn?t delay the creation of the Foundation.

5/ ZC contradictory statements
Some examples :
-The statement that the trademark was protected in 2003, while it was  
not outside the US.
-The ownership of the trademark seems to be a primary concern of ZC,  
at the same time ZEA and other registrations went unnoticed.
The reasons of these contradictions aren?t clear today: lack of  
resources, misunderstanding of international laws, problem of  
expertise of their trademark expert?
The fact is that leaving the trademark unregistered outside the US  
has put the Zope ecosystem at risk: other brands could have opposed  
the registration. It also weakens Rob point (July20) that ? ZC is  
more likely to defend the trademark than a volunteer-led Foundation ?.

B - Concerns about Zope future
For over 3 years I have been following the discussions about Zope,  
met a number of developers, businesses and users. Legal concerns  
including the trademark are ongoing topics brought up by a large  
number of persons (in and out ZEA). This situation is damaging the  
Zope Community and related activities. I believe it is time to tackle  
the roots of the problem or drop the topic. The Zope Community should  
own this decision.

Since Europython (point1), I had a number of direct contacts with ZC.  
What struck me most is that:
-the same word ?Zope? (brand) is being used for different goals and  
objectives,
-the unwillingness of ZC to talk about core issues.

The 2 points of views :

(a)- Zope community, businesses and users
Worldwide, Zope refers to ?Zope the open source application server?.  
It is the brand of the technology originally presented to the public.  
Thousands of people are promoting it. The future of Zope relies on  
the ability to grow its ecosystem and be attractive to new businesses  
and users.

(b)- Zope Corporation
ZC point of view is ?Zope is Zope Corporation?. The same name is used  
for a business, its products and (a).

The goals and objectives of (a) are not the same as (b). All actions  
taken by (a) bring a benefit to (b). The reverse is uncertain. Zope  
Corporation is in a clear position of conflict of interest. ZC owns  
the problem : it is a consequence of the decision to rename their  
business.

An example of distortion : ZC has never done marketing in Europe,  
while the activity of (a) brings a direct return. Since June 29, I  
was surprised that the information ZEA received from ZC focused on  
(b) rather than (a); whatever the consequences for (a) and the market  
might be.

I?m not an expert in US laws, but from a European perspective, and at  
least in my country the same conflict of interest underlying a  
Foundation would automatically disqualify it. By law, a non-profit  
cannot provide direct benefits to one of its founder or member.

Many of us can already witness some consequences of these conflicts  
of interests:
- it creates mistrust about ZC actions,
- the use of the name ?Zope? remains a hot topic,
- this situation is damaging Zope (a).

The sad thing about this situation is that a number of businesses  
have already taken actions to reduce their dependency on the Zope  
brand, while others remain concerned about these ongoing issues. The  
consequences have a broader impact than the trademark alone: it is a  
strategic issue slowing down Zope growth internationally.

I believe ongoing success and how to achieve it are the core issues  
we should focus on.
Best regards,

Xavier Heymans
CEO, Zope Europe Association
========

Note 1 : The emails posted on zope.org by Rob and Hadar contain  
factual errors and contradictions. Matt Hamilton already came up with  
some examples. I do not wish to spend further time arguing this. I  
would like to express some concern about the way the information is  
being handled.

Note2: On Friday July 15, I informed ZC that I would be several days  
away from the office and we would need extra time to review their  
propositions send the same day. This letter includes a commitment to  
refund ZEA trademark expenses, which was an earlier point of  
divergence. We appreciate this step and positive propositions posted  
by Rob on Zope-annonce. To avoid delaying the present answer, next  
week I propose to :
-    analyze in detail the different propositions,
-    summarize ZEA questions and propositions about these points.

It does work. The comment is wrong. If you find something that does  
*not* work I'll be glad to look at it, but so far you have not given  
any specific information about breakages like tracebacks or steps to  
follow to produce an error.

In a sense, the id becomes part of your API.

Your script would become:
 
attrobject = getattr(context, 'some_id', None)
return attrobject

I can't give this information because it doesn't raise exceptions. It
works (not raise errors), but not properly.

I never saw an example of ZSQL Methods running from file system in CMF,
can you give me this?

My intention is just contribute, however, solving a real problem I have.

HAHAHHAHA!!! LOL!

Man!  There has got to be some humor in this at some point!

Honestly, though, I appreciate your discussions being held here.  I
truly appreciate the fact that I have Zope to work with and offer to
my customers.  I feel that I owe that thanks not only to Zope
Corporation, but to the community as well.  I just wanted to chime in
from a tiny part of the *silent majority* so that both parties hear
it.  I love Zope, we all do.  Work this out. :-)

Take a look at the unit tests which exercise the FSZSQL code, there  
is a sample one that is part of the fake skins directory used by the  
CMFCore unit tests:

http://svn.zope.org/CMF/trunk/CMFCore/tests/fake_skins/fake_skin/ 
testsql.zsql?rev=37165&view=markup

You're still giving no clue about what exactly it is that works "not

from Acquisition import aq_inner, aq_parent

parent = aq_parent(aq_inner(self))

This will return the true container the instance is set in, not just  
the acquisition parent.

I looked at your example and I understood the correct sintax, now it 
make sence, the <dtml-comment> comments the attributes in the body of 
ZSQLMethod.

But in my refactory of parser I used a more elegant sintax to the file 
like Script Python, and does not leave the trash (<dtml-comment> 
arguments </dtml-comment>) in the body of the method.

I only wait that someone test my reimplementation of parser and says me 
it's really insignificant.

I would like at least not to have that trash (<dtml-comment>...) in the 
body of the method.

Regards!

Message-ID: <20050722191507.D09A41B75F@yoda.cefetcampos.br>

Hi,

I have a few questions about Plone (in some extent CMF/Zope):

1)How to manipulate versioning in Plone? (like CPS does)
I know there is PLIP8, but it is still a proposal, isn't it?

2)How to store and catalog huge document collections?
-LocalFS + ZCatalog?
-Implement mapping and indexing in a relational DB?
(I have also de ERP5's ZSQLCatalog option...)

3)Is there any product or Plone plug-in that allows enhanced searches
through thesaurus or ontologies, or something like this?
I know there are Ontobroker and Gnowsys, but I would like
to have something simpler to work on top of Plone.

thanks for the help,

As far as the CMF goes, IMHO it doesn't make much sense to put code  
into the repository just because one person doesn't like the way  
arguments are handed to these ZSQL methods. They work perfectly as is.

I fail to see how several lines of double-hash-escaped lines is any  
less "trash" than the comment-tagged version that is there right now.

I'm not sure, but isn't this something you configure with the front-end http 
server (ie. Apache)?

Yes. See the "servers" directive in zope.conf, which documents all  
this very well.

Two things:

- simply using aq_parent does not guarantee giving you the real  
containment parent. Depending on the path used to access the object  
it could be something different from the true containment parent.  
That's the power of acquisition...

- direct attribute access like that makes me feel dirty. I prefer the  
true object-oriented style where you use methods to get at stuff.

Subject: [Zope] zoperun vs start and ssh
Message-ID: <3cf08c81050723104660d35b7b@mail.gmail.com>

This may be a stupid question, but, after searching the archives to
find out how to keep Zope running after starting and then
disconnecting from a remote ssh session, nothing works.

First, the Zope manual and all the archives messages talk about using
./start. That doesn't work for me unless I am just in the wrong
directory. I am running ./zoperun from /bin.

Using nohup and & doesn't keep Zope running when I log off my remote session.

Any ideas? Thanks.

Subject: [Zope] Searching Content Objects in Zope 3
Message-ID: <20050723180145.96796.qmail@web25705.mail.ukl.yahoo.com>

Hello,

I've been working away on an application, and it's now
starting to take shape, based around a series of
content objects.

As recommended on this list I opted for Zope 3 to
build my app, and I'm finding it quite powerful.
However, I've hit a bit of a brick wall around
searching.

It seems from the documentation that ZCatalog is the
prefered way of doing a search in Zope 2, but that
this isn't implemented in Zope 3. I've got Philipp von
Weitershausen's (very good!) book, and he doesn't
implement a search for his recipe objects. I've also
been looking at the PDF of the Zope 3 Book (which I've
also found really useful) and I haven't spotted
searching of objects mentioned in that.

My search tool will need to take various criteria
(say, number of bedrooms, maximum rent, areas the
property can be located in) and scan through my
objects to find all the matches.

I think I can work out how to search through the
objects themselves in order to find the matches, the
real problem is taking in the criteria in the first
place. (Although, any tips provided on the searching
side of things would certainly be welcome too!) As a
'dummy run' at searching I created a View for my
PropertyFolder object that shows properties based on
specified criteria - I can get this to work OK, but I
have to put the criteria right into the Python code,
so clearly that's not acceptable...

I would be grateful for anything anyone could point me
to that would help me to build a tool to search my
content objects. Philipp mentions the use of Utilities
for searching, but beyond that, I don't know where to
start. Is it possible to use Interfaces to create data
entry schemas/forms for Utilities in the same way as
for objects? 

Any help, greatly appreciated.

Thanks,
Jim

The "start" script was used in Zope versions up to 2.6.x, replaced by  
"zopectl" for safely starting and stopping Zope in the 2.7-series and  
up. Apart from that, packages that are put together by other people  
or by Linux distribution maintainers may have their own scripts.

I have no idea what "zoperun" is, I'm assuming you mean "runzope.py",  
which is part of 2.7.x and up? If not then this smells like some non- 
standard package, you should contact its maintainer.

In case you don't get help here, you should subscribe to the specific

Oops, I meant to say runzope. I got Zope from the Zope web site,
Zope-2.8.0-final.

This is a system administration problem, not a zope problem. :D

If you want to start zopectl ever you need to configure it on 
/etc/init.d/ with rc-update.d on debian or chkconfig on fedora.

Yo use a ssh session and start your service and if you close ssh 
connection you close the application too.

See on you distro for config process to start on your /etc/init.d/

Bye.

Subject: [Zope] Token 'ATOM' required, 'and' found
Message-ID: <bc95c28005072312461ca7f017@mail.gmail.com>

I'm using zope 2.7.5 and when doing a catalog search in a ZCTextIndex
containing the starting with the word "and" it barfs with this errror:
E.g. http://www.peterbe.com/search?q=and+i+cant+stop+thinking+about+you

Error Type: ParseError
Error Value: Token 'ATOM' required, 'and' found
(traceback below)

It works perfectly fine with 
http://www.peterbe.com/search?q=i+and+cant+stop+thinking+about+you
because then it doesn't start with "and".

The easy fix is so do something like this:
  if q.lower().startswith('and'):
      q= q[3:]
  results = self.Catalog.searchResults(title=q)

But, is there a more robust solution to this? One that doesn't require
hardcoded English words in the code. Is there a way to escape "and"
and "or" to treat them as actual words?

Subject: [Zope] Puzzling Import/Export problem
Message-ID: <42E2A40E.20502@vt.edu>

A friend in Russia is still using my old ZClasses QSurvey product.

He is attempting to copy an installation from one machine to another, 
and upgrade Zope to 2.6.4.

Exporting the product and instances works fine, but some object 
instances will not import correctly.

A product instance is a folderish object that contains other objects.  
One particular folderish subobject will not import correctly; all the 
others import fine.  The .zexp of the entire product instance, with 
subitems, etc., imports OK, but the one folderish object shows up as 
"broken" in the ZMI.

Exporting that object as XML and reimporting after correcting the 
appropriate class ID string results in a "BadPickleGet" error 7.

Traceback (innermost last):
  Module ZPublisher.Publish, line 113, in publish

BadPickleGet: 7


I have examined the xml export, and the only thing I can think of that 
might be a problem is that some of the object IDs for some contained 
items are base64-encoded and may contain Russian characters.  But that 
does not seem to be the problem, since a similar, smaller import with 
only ascii characters fails with the same traceback and BadPickleGet:10.

I realize that this might be an uninteresting edge-case.  My backup plan 
is to write a script to pull the data out of the XML export and recreate 
the objects.  Does anyone have any pointers on that?  I am having 
trouble figuring out how that file is organized.

For completeness, I am using zope-2.8.0, but this happens on 2.7.6 as well.

With zopectl the "&" is unnecessary. It does all the right things to  
go into the background and detach from the terminal by itself without  
the ampersand.

nothing ready i think, but for a generic library that enables you to 
perform complex queries over a catalog google fro Dieter's AdvancedQuery 
product. Also, it is possible to implement ontologies in plone using 
Archetypes references and maybe using the Relations product (always from 
  Archetypes svn o)

I want to post a update date that will change when any of the objects in a folder has been updated.
 
So far, I only know the command bobobase_modification_time, but it only works again the object I I enter the command with.. 
 
Can anyone show me how this is done??

This is not a command. This is a method!
Methods are called "on" an object.

so if o is your object,

o.bobobase_modification_time()

returns the internal storage time of that object.

Maybe its a good start if you read the python
tutorial (www.python.org) to get an idea on all
that object, method, attribute stuff.

Hi!

How can I get the product's path while instantiating it? Shouldn't
this information exist somewhere? aq_parent(aq_inner(self)) returns
None, which isn't totally unexpected since __init__ isn't strictly a
Zope method and thus doesn't necessarily have a Zope method's context.

(I need, from the __init__ method of a product, to find out its
instantiation path in the ZODB.)

TIA,

Use manage_afterAdd(). There is no acquistion context available during the
construction phase where __init__() is used.

Then stop being dense and just use Apache as an https proxy. Works a

Hi Chris. I believe the purpose of ZTUtils are utility functions for 
page templating. That said, the Iterator class could be more useful by 
exposing its values based on its state -  the point I had made.  
Versatility is the beautiful thing about python  - it rarely matters to 
me what intention there is or may have been for a class so long as it 
supplies the methods I am after.  In the end, there's really nothing 
here that can't be solved with a simple tool and a bit of flexibility 
on my part. Many thanks.

Regards,
David

Which is why the 'aq_inner()' call is in there:  it strips away
non-contaiment wrappers.

The actual issue is that attribute access will break if you have an
unwrapped object;  'aq_parent(foo)' will return 'None' in that case.

(A tiny nit, 'aq_parent()' and the related 'aq_base()' and 'aq_inner()'
are module-scope functions, rather than methods).

You can find the relevant code in

In principle, the code should try all sockets between
"19999" down to "19950" and fail only when none of them

As usual, you must get and look at the corresponding traceback.
It will tell you where "__str__" is inappropriately used.


If the error is generated from your "standard_error_message" (what
you might call "standard_error_html" -- Note: it is very important
to use the precise names!), then it may not be that easy to
get the traceback. In our Zope copy, I have introduced a log
call in case "standard_error_message" raises an exception to get
at this traceback.
The place for this measure is in
"OFS.SimpleItem.SimpleItem.raise_standard_error" (or similarly named).

The complete calling statistics is very complex.
Therefore, the profiler does not record the complete information
but only summary information.

Especially, it only records the time spend in a given function (say "X")
but not the different times when "X" is called in different
contexts (e.g. by "A" and "B").
As a consequence, the timings given by the "callees" view are usually
too large for the given context (they show the "X" is called by "A"
but the time given for "X" is the total time spend during any call of
"X" and not only any call from "A").

By itself, Zope does not support SSL.

Thus, the problem might be in "ZServerSSL". Consider to contact its author.

This error comes from your mail server.
Checks its (the mail server's) documentation to make sense of it.

This reminds me a discussion between two business students:

  They planned how to make money with little effort.
  Their business plan looked like this:

    Check in which countries Coca Cola (or some other large quickly
    expanding company) has not registered its trademarks.
    Register them and wait until Coca Cola recognizes its error.
    Let them pay for the transferal of the trademark rights.

This discussion convinced me that the trademark laws are almost
as bad as the patent laws...


I do not know ZEA and do not know whether they hired business students
like the above....

But it looks very suspicious when they say that they registered
logos they did not design for protective reasons *without*
informing the company that officially use these logos (and paid for the
design) *before* the registration...

runzope command. But I got below error. I am
using gobolinux and Python 2.3.3 for this zope
version.
    I try to install some other zope version eg
(2.7.6,2.8.0 and 3.0.0) all the different
version of zope have the same problem.
Kindly let me know what is the problem of
zope installation.

It looks like this part of the Iterator is just misdesigned:

    def next(self):
        if not (hasattr(self, '_next') or self._prep_next(self)):
            return 0
        self.index = i = self.nextIndex
        self.nextIndex = i+1
        self._advance(self)
        return 1

IIRC, ZTUtils were written long before the python iterators became
standard. So the method name next was used and now clashes with
the standard iterator protocol.

It could be fixed but only if there is no product in the world using
it or all must be fixed before.

I propose: has_next() or something in place of it.

Take your pick I guess ;-)

The "correct" thing to do here is to write your own query parser, but 
that's a lot of hard work.

I just catch the two exceptions that the QueryParser can throw and 
return an empty result set.

Message-ID: <AD11348A-B1A3-4265-A09B-EADD62D4AEE3@iinet.net.au>

Hi,

This is a bit OT but this list is the best place I know to ask it :)

I have a form which uses UTF-8, the text entered in the form then has  
to be converted to iso-2022-jp. If any character is entered that  
isn't valid for iso-2022-jp I get:

UnicodeError: ISO-2022-JP encoding error: invalid character \u2013

What I need to do is display the offending character in the error  
message. So the question is, how do I take the '2013' and display the  
appropriate character?

TIA, Itai

Ok. Sounds like a plan. 
What I need to do if it happens is to escape all the operator words
like "and" "or" "not".
Any idea how I can do that?

Not a zope solution (or issue), but how about using regex in python code?

Finding the words I'm not worried about. What I don't know is _how_ to
escape the words.
If it was putting it in square brackets i _would_ do:

  q = q.replace('not','[not]')

Don't get hung up on that. What I'm after is the technique I can use
upon the QueryParser for "ignoring" these operator words.

RTSL ;-)

QueryParser.py has a massive doc string at the top of it ;-)

Hello,

 

Does anybody use the zip upload in the latest Photo product (1.3.0) ?

 

There is a ftp bug in that release but is has a zip upload feature (that
also doesn't work with me).

 

I use Zope 2.7.7 on a Red Hat fedora core 4.

 

Thanks for the help.

Well, nothing has changed in the mail server setup so I don't know why
this error is being thrown. Where can I access smtplib (I cannot locate
this Python library in my Zope hierarchy)? Someone else also reported
receiving this error as I discovered on Google but the issue was not
resolved. Any help would be appreciated. Thanks.

Subject: [Zope] working with urls
Message-ID: <20050725133930.56936.qmail@web25610.mail.ukl.yahoo.com>

First of all thanks everyone for the help, I've resolved my problems one after the other thanks to the suggestions I've found here.
 
Now I'm rewriting urls by substituting the href attribute with custom data, and everything works fine.
What I'd like is having an url like: myproduct/generate/20050301/PG2, and actually that's exactly what I've got. This url will make my app generate a pdf report for the ref_date 2005/03/01 and code PG2 (ref_date and code are internal data).
Zope obviously maps the url as an object, but that's not what I want: I want to parse the url and use the ref_date and code data inside a generate method.
Is it possible inside Zope without mod_rewriting and similar stuff ? I don't like querystring, the resulting url would be too long and difficult to paste.
I know that this is not the way Zope works ...
 
TIA,
  ngw

Why don't you identify the variable data portion of the urls you are building as standard http-type arguments:

eg.    http://www.myweb.com/amethod?var1=val1&var2=val2...

This way var1, var2 etc will be accessible to your method as entries in REQUEST.

Because it's a bit ugly - my url will grow a lot, because I have to include the variable name. It's also really simple to make the product generate a PDF if the user know the ref_date and code, without playing with variable names.
 
Obviously if it's not possible I will generate a normal querystring, no problem at all, I'm just curious to know if it's possible to have urls like in ruby on rails :)

Maurer, I am certain that this is a Zope issue that has not been figured
out as yet. I was even able to connect to my SMTP server via the Terminal
application on a Mac. Do I have any other options?

You should do a network trace to see what makes the SMTP server puke.

I am a newbie to Zope/Plone.

I am trying to view the Zope API via the Help System in the ZMI, but I get
prompted to login and my admin login does not work.

I'm pretty sure I downloaded the latest version of plone which I was led to
believe would have the latest version of zope & python:

Zope Version
	(unreleased version, python 2.3.3, win32)
Python Version
	2.3.3 (#51, Dec 18 2003, 20:22:39) [MSC v.1200 32 bit (Intel)]
System Platform
	win32

If I do not have the latest version of zope for my plone instance, how can i
upgrade?

Thanks for any help,

Ed.

Yup.  ZODB has what looks like a copy/paste of this code, in
ZEO/zrpc/trigger.py.  I didn't realize where it came from originally
until you pointed out the Medusa code here.

Anyway, it so happens I rewrote ZEO's copy a few weeks ago, in ZODB
3.4.  The Windows part is much simpler there now.  I don't know why
the original might fail in the way Sune reported, but perhaps the
rewritten version would not.

Before:

            # tricky: get a pair of connected sockets
            host='127.0.0.1'
            port=19999
            while 1:
                try:
                    self.address=(host, port)
                    a.bind(self.address)
                    break
                except:
                    if port <= 19950:
                        raise BindError, 'Cannot bind trigger!'
                    port=port - 1
                    
            a.listen (1)
            w.setblocking (0)
            try:
                w.connect (self.address)
            except:
                pass
            r, addr = a.accept()
            a.close()
            w.setblocking (1)
            self.trigger = w

After:

            # Specifying port 0 tells Windows to pick a port for us.
            a.bind(("127.0.0.1", 0))
            connect_address = a.getsockname()  # assigned (host, port) pair
            a.listen(1)
            w.connect(connect_address)
            r, addr = a.accept()  # r becomes asyncore's (self.)socket
            a.close()
            self.trigger = w

Subject: [Zope] Re: ZTUtils.Iterator value in ZPT
In-Reply-To: <1122282218.30587.85.camel@Andrea.peacock.de>
Message-ID: <B90293C8-FD19-11D9-9A80-000A27B3B070@eastlink.ca>

New methods on the iterator would do the trick.  I had suggested 
currval and nextval or similar - two or three simple methods would 
increase the versatility of the Iterator class for a variety of things. 
Is there interest in adding new methods to ZTUtils to expose these 
values?  It seems to fit the purpose of ZTUtils and would save making 
another tool at site or portal level.  The fact is it doesn't have to 
be a portal / portlets type of situation to benefit from this. It is 
not CMF specific in the least and would be useful in any multi column 
layout using ZPT where you need values for tabindex attributes without 
hand coding (particularly when your content is dynamic).

If there is no interest, I'll leave this alone and carry on with a 
portal tool for my CMF work instead.  ZTUtils is really core Zope issue 
so if there is interest, I can create a few methods but need some 
direction on what to do with them afterwards.

Regards,
David

IssueDealer installs several folders in the Products subdirectory:

   > IssueDealerWebLog
   |

   > IssueDealerWebLogAddOn

No errors are showing up in the logs files.

Any other ideas? I contacted the IssueDealer team last week, but haven't
heard a peep.

You want to write a __bobo_traverse__ method for your class:

     def __bobo_traverse__(self, REQUEST, name):
         # do something with 'name' here.
         return an_object_that_is_to_be_published

The only other suggestion I have is to dig thru the IssueDealer source code 
and try to debug it yourself (given that there is no help from the author). 
If you are not familiar with zope product development you can google for:

site:www.zope.org boring product
site:www.zope.org simple product

Warning: debugging someone else's product may not be a trivial exercise if 
you are not familiar with zope product development (and python)!

Do these directories and the files in there have the correct
permissions set so that the user Zope runs as can access the files?

I prefer to use __before_publishing_traverse__(self, obj, REQUEST=None)

The IssueTrackerProduct (IssueTracker.py) uses this so that you can URLs like
/ListIssues/start-20/reverse-False 
instead of
/ListIssues?start=20&reverse=False 
but that is just slightly different from what you are after. 
Good luck

Simplest might be to point a Path Handler
(http://www.zope.org/Members/NIP/PathHandler) named
'generate' at your PDF generator script.

Also, a Script(Python) 'generate' containing:

return traverse_subpath

when called http://mysite.com/generate/foo/bar/baz
returns:

['foo', 'bar', 'baz']

This could be useful for the URL re-writing you want.

I would like to inform that ZEA is in the process to transfer the  
trademark to Zope Corporation. A number of actions will be taken  
including the preparation of the list of expenses to secure the  
trademark, and meetings with our trademark expert to work on the  
administrative details.

We would like to emphasize that no action taken by Zope Europe  
Association are illegal from a European perspective. As said   
earlier, our action was aimed at securing the mark stopping third  
party registrations.

Best regards,

Xavier Heymans
CEO, Zope Europe Association

".0" releases often have problems.

I recommend to switch to the latest "2.7" release (which is
2.7.7 or maybe even 2.7.8).

Such problems are best analysed with the "VerboseSecurity" product.

Install it and report what it tells you.

Have a look at "PythonScript"s "traverse_subpath" binding.

I would expect that you find a description in the Zope Book
(2.7 edition, online).

Usually, it is much safer to just copy the storage file(s).

Export/Import is known to fail with ZClasses that inherit
from other ZClasses defined in a different product (which probably
is not your case).

This usually means that its class could not be imported.

Have a look at Zope's "ClassFactory" and check why it is unable
to import/load the ZClass.

I what encoding?

Obviously, you cannot use "ISO-2022-JP".
If you can handle "UTF-8", then use "unicode('\u2013').encode('utf-8')".

You can also use the "xmlcharref" error parameter for your
"encode(iso-2022-hp)". In this case, your character would 
become an XML character reference. They have the form
"&#x2013;". Browsers usually are able to display them.

"smtplib" is part of the Python runtime library.

Looking at the "smtplib" source and your traceback reveals:

  "smtplib.SMTP.__init__" is trying to determine the
  local hostname. The code looks like this:

        if local_hostname is not None:
            self.local_hostname = local_hostname
        else:
            # RFC 2821 says we should use the fqdn in the EHLO/HELO verb, and
            # if that can't be calculated, that we should use a domain literal
            # instead (essentially an encoded IP address like [A.B.C.D]).
            fqdn = socket.getfqdn()
            if '.' in fqdn:
                self.local_hostname = fqdn
            else:
                # We can't find an fqdn hostname, so use a domain literal
                addr = socket.gethostbyname(socket.gethostname())
# your exception is raised in the line above
                self.local_hostname = '[%s]' % addr
  

This means that you local system is in a strange state.
Probably, it is unable to determine its hostname.

Try (in an interactive Python interpreter):

    import socket
    socket.gethostname()
    socket.gethostbyname(socket.gethostname())

This may even be portable (not Windows specific).
At least, it works for Linux2.

In this case, we might get rid of the stupid code duplication...

Thanks Dieter. You hit the nail on the head. socket.gethostname() is not
returning the full canonical name of the machine. But how do I correct
this? Any idea?

I believe it is portable, but the Unix version of this code doesn't
use sockets at all.  It uses a pipe instead.  A pipe can't be used on
Windows because the Windows select() works only with sockets, and
asyncore on Windows uses select().  I don't know if/why a pipe would
be better on Unix, but just assume that it is.  I do know that the
Windows version of this code used to leak sockets madly, for years. 
The pipe code is simpler still.

> In this case, we might get rid of the stupid code duplication...

Well, there are two kinds:

1. Massive code duplication between the "posix" and "not posix"
versions of the `trigger` classes.  I already refactored ZODB's copy
to eliminate that (most of the ZODB 3.4 trigger code is in a shared
base class now, and the "posix" and "not posix" versions override just
enough to make the pipe-versus-socket-pair distinction).

2. Massive code duplication between ZODB's copy and Medusa's.  Hmm. 
Since I refactored ZODB's copy, it's hard to tell that they have
anything in common anymore ;-)

Thanks, Dieter.

Couldn't get it to work, though... not sure why: unicode('\u2013')  
returns u'\\u2013', which is useless.

Just found the unichr method though. unichr(int('2013', 16)) does the  
job.

Is there any bechmarks already posted on the web??

We're using dual cpu (not dual core) 64bit AMD Opteron (Sun Fire V20's)
based systems and are VERY impressed with their performance; our python
benchmarks show dual Opteron 250 systems outperforming dual twin-core
Xeon 3.6GHz with the same code. Almost everything we run is ZEO based
and hosted over 2 or more boxes (7 or 8 in the case of our biggest
system). We couldn't be happier with the combination of Opteron and ZEO.

We benchmarked 64bit Opteron, 64Bit UltraSparc III, 32bit Xeon and 64bit
Xeon for our applications. Opteron trounces them all in day to day use.

Sun's dual core Opteron offerings are coming out VERY soon. So that will
make the V20 a 4-way system, and the V40 an 8-way system!

As a guide, our standard spec for a ZEO hosted Zope server is 2 x
Opteron 250/252, 4Gb, dual Gbit NIC, dual 10krpm SCSI drives in RAID1
(the main ZEO backend server is a similar spec but utilising a big SATA
array in RAID50). We've found we can host 6 or so big sites (resident
seize of 250mb or more) on each node and still get excellent performance
by duplicating across several nodes. We have ZEO served sessions and use
Pound to load balance across the pool without any stickyness - meaning
on each page access users will (potentially) go to a new box - resulting
in much finer grained balancing and use of resources.

Performance is *excellent*.

Thanks for the pointer. I have been debugging
select_trigger.py, and has some more info:

The problem is that the call a.accept() sometimes hangs.
Apparently a.bind(self.address) allows us to bind to
a port that another zope instance already is bound to.

The code creates the server socket a, and the client socket w,
and gets the client socket r by connecting w to a. Then it closes a.
a goes out of scope when __init__ terminates, and is probably garbage collected 
at some point.

I tried moving the code to the following standalone script, and I can reproduce 
the error with that. In the original code w is kept as an instance variable, and 
r is passed to asyncore.dispatcher.__init__  and probably kept there. I simulate 
that by returning them, then the caller of socktest can keep them around.

I try to call socktest from different processes A and B (two pythons):
(w,r = socktest())
The call in A gets port 19999. The second call, in B, either blocks, or takes 
over port 19999 (I see the second process taking over the port in a port scanner.)

a.bind in B does not raise socket.error: (10048, 'Address already in use') as 
expected, when the server socket in A is closed, even though the port is used by 
the client socket r in A.

If I remove a.close(), and keep a around (by passing it to the caller), a.bind 
works as expected - it raises socket.error: (10048, 'Address already in use').

But in the litterature on sockets, I read it should be okay to close the server 
socket and keep using the client sockets.

So, is this a possible bug in bind() ?


I have tested the new code from Tim Peters, it apparently works, ports are given 
out by windows.
But could the same problem with bind occur here, since a is closed (and garbage 
collected) ? (far less chance for that since we do not specify port numbers, I 
know).

I tried getting a pair of sockets with Tim's code, and then trying to bind a 
third socket to the same port as a/r. And I got the same problem as above.

Unless you're using a very old Python, `a` is collected before the
call returns (where "the call" means the call of the function in which
`a` is a local variable).  Very old Pythons had an idiotic __del__
method attached to their Windows socket wrapper, which inhibited
timely gc.

Yes, the socket bound to `r` also gets bound to `self.socket` by this call:

    asyncore.dispatcher.__init__ (self, r)

Sorry, I can't reproduce this -- but you didn't give a test program,
just an isolated function, and I'm not sure what you did with it.  I
called that function in an infinite loop, appending the return value
to a global list, with a short (< 0.1 second) sleep between
iterations, and closed the returned sockets fifty iterations after
they were created.  Ran that loop in two processes.  No hangs, or any
other oddities, for some minutes.  It did _eventually_ hang-- and both
processes at the same time --with netstat showing more than 4000
sockets hanging around in TIME_WAIT state then.  I assume I bashed
into some internal Windows socket resource limit there, which Windows
didn't handle gracefully.  Attaching to the processes under the MSVC 6
debugger, they were hung inside the MS socket libraries.  Repeated
this several times (everything appeared to work fine until > 4000
sockets were sitting in TIME_WAIT, and then both processes hung at
approximately the same time).

Concretely:

sofar = []
try:
    while 1:
        print '.',
        stuff = socktest()  # calling your function
        sofar.append(stuff)
        time.sleep(random.random()/10)
        if len(sofar) == 50:
            tup = sofar.pop(0)
            w, r = tup
            msg = str(random.randrange(1000000))
            w.send(msg)
            msg2 = r.recv(100)
            assert msg == msg2, (msg, msg2)
            for s in tup:
                s.close()
except KeyboardInterrupt:
    for tup in sofar:
        for s in tup:
            s.close()

Note that there's also a bit of code there to verify that the
connected sockets can communicate correctly; the `assert` never
triggered.

You haven't said which versions of Windows or Python you're using.  I
was using XP Pro SP2 and Python 2.3.5.  Don't know whether either
matters.

It was certainly the case when I ran it that your

>         print port

statement needed to display ports less than 19999 at times, meaning that the

>             a.bind((host, port))

did raise an exception at times.  It never printed a port number less
than 19997 for me.  Did you ever see it print a port number less than
19999?

I'm not sure what that's saying, but could be it's an illusion.  For example,

>>> import socket
>>> s = socket.socket()
>>> s.bind(('localhost', 19999))
>>> s.listen(2)
>>> a1 = socket.socket()
>>> a2 = socket.socket()
>>> a1.connect(('localhost', 19999))
>>> a2.connect(('localhost', 19999))
>>> b1 = s.accept()
>>> b2 = s.accept()
>>> b1[0].getsockname()
('127.0.0.1', 19999)
>>> b2[0].getsockname()
('127.0.0.1', 19999)
>>>

That is, it's normal for the `r` in

>     r, addr = a.accept()

to repeat port numbers across multiple `accept()` calls, and indeed to
duplicate the port number from the `bind` call.  This always confused
me (from way back in my Unix days -- it's not "a Windows thing"), and
maybe it's not what you're talking about anyway.

As above, I'm seeing `bind` raise exceptions regardless.

Sure feels that way to me, and I'm not seeing it (or don't know how to
provoke it).  But I'm not a socket expert, and am not sure I've ever
met anyone who truly was ;-)

Here I'm not sure what "the same problem" means, as you've described
more than one problem.  Do you mean that you get a hang?  Or that you
see suspiciously repeated port numbers?  Or ...?  Seeing concrete code
might help.

Last question for now:  have you seen a hang on more than one flavor
of Windows?  Thanks for digging into this!

I know why (now, that you report the problem).

  '...' introduces a non unicode string in which "\u" is not recognized.
  "\u" is only recognized in unicode strings.
  They are introduced by "u'...'".

Thus, instead of "unicode('\u2013').encode('utf-8')", I should
have written "u'\u2013'.encode('utf-8')".

"gethostname" is not required to return the FQDN (Fully Qualified Domain Name).
This is not your problem.

But "gethostbyname(gethostname())" should be able to resolve
whatever "gethostname()" returns into an IP address.


If you already told us the platform you are using, then I missed
this information (or forgot it).
If you work under *nix, you may add an entry to "/etc/hosts"
that assigns an IP address to the value "gethostname()" returns.

I cannot help you much when you work under some variety of Windows.
But, I know, Windows knows a "hosts" file as well.
Maybe, the same approach works there, too.

This is wrong.

In the early days of the Foundation, we had no proper legal representation  
and asked ZEA to represent us while setting up the legal entity for the
Foundation.

Plone Foundation therefore asked ZEA to assist us with their trademark  
experts to register the Plone trademark worldwide. This is perfectly clear  
 from the publicly available Plone Foundation board meeting minutes.

They did the work on our behalf, and most excellently executed the  
worldwide registration of the mark. The trademarks were transferred fully  
to the
Plone Foundation as agreed.

As a result, Plone Foundation owns the worldwide trademark for Plone.

So any idea why the WIPO database tell us a different story?

As usual, my question is rather simple :)
I'd like to know what are the best practices for product organization - for example I have _tons_ of queries to sqlserver, and my main class is becoming less manageble every time I look at it :/
I like the way SQL integrates in Zope, what I don't like is having a giant __init__ and a lot of _sqlSomething at the end of the class.
 
Can I associate queries to something else than a _variable ? Something like a dictionary or a class ? Can I move SQL calls outside the initializer ? I'd prefer to have a class for data access and another one to glue all the parts together, maybe I'm plain wrong but I think that my product would be a lot cleaner.
What are the best practices for FS based products ?

I can't talk for best practise. You can put your queries also outside of
the init, in this way:

class YourProduct:

	_my_query = SQL('doMyQuery', '',
		'your_connection', '', 'select * from data')

	def __init__(self):
		pass


Also, if you have a *LOT* of queries, consider in building your query on
the fly.

Subject: [Zope] unwise.exe missing on linux
Message-ID: <134b8b7105072703304e9747c7@mail.gmail.com>

Hi

Does anyone know if the zope uninstall program 'unwise.exe' can be got
separately? I have installed zope on linux but the unwise.exe program
isn't within the package.

Thanks

Michael

Subject: [Zope] ZPsycopg - Losing Connections
Message-ID: <FF265DF2-744E-4BC9-91FC-8AF9FCE7C450@talamh.org.uk>

Python 2.3.5 - Zope 2.7.5 - PostgreSQL 7.3.4 - Psycopg 1.1.18 -  
Solaris 8 (Intel)

Hi

I am experiencing a new problem, that was not present in the past on  
the above server. From the Zope error log:

Exception Type      OperationalError
Exception Value    PQsendQuery() -- There is no connection to the  
backend.
Traceback (innermost last):

Module ZPublisher.Publish, line 92, in publish
Module ZPublisher.BaseRequest, line 433, in traverse
Module Products.exUserFolder.exUserFolder, line 869, in validate
Module Products.exUserFolder.exUserFolder, line 1133, in listOneUser
Module Products.exUserFolder.pgAuthSource.pgAuthSource, line 244, in  
listOneUser
Module Shared.DC.ZRDB.DA, line 454, in __call__
<SQL instance at 922dd70>
Module Products.ZPsycopgDA.db, line 228, in query
OperationalError: PQsendQuery() -- There is no connection to the  
backend.

When I check in psql, I can see a connection still being there.
Using the query:
SELECT count(pg_stat_activity.datname) AS count,  
pg_stat_activity.datname FROM pg_stat_activity GROUP BY  
pg_stat_activity.datname;
(Is this really showing active connections? Or just recent usage?)

If I use the close connection and then open connection buttons in the  
Z Psycopg Database Connection in Zope, I get the connection usually  
back. Sometimes I have to re-submit the properties to make it work,  
though.

Properties settings are:
"Connect immediately" is checked
"Use Zope's internal DateTime module (instead of mxDateTime)" is checked
Transaction isolation level:  Serializable
Backend encoding: UTF-8
"Output Unicode strings" is not checked

This is fast becoming a real headache for us!

What has changed? We have recently increased the max_connections and  
shared_buffers for PostgreSQL and now run more Zope instances with  
now averaging about 40 connections from the database (using the query  
above). So this is an increase.

Any help on how I can find out what's going on here is very welcome!  
(or in short: HELP, PLEASE!)

Cheers

That's because unwise.exe is only needed if you used wise to install
it. Which you only can if you are on windows.

On Unix you uninstall Zope by deleting the directory.

Well, not exactly - just a way to separate access to data from everything else in the product.
Maybe a separate class that needs the connection as argument and that just returns the data I need in appropriate data structures by calling class methods.
 
class DataModel (object):
 
  def __init__ (self, conn):
    self.conn = conn
    self.sqlFetchSomething = SQL (.....)
 
  def fetchSomething (self):
    return self.sqlFetchSomething
 
This is really simple, but I think it gives the idea.
Obviously I'd like to perform various operation at the data level, for example return a list of lists for reportlab tables and so on.
 
TIA,
  ngw

I will try to recreate the problem on other
flavours of windows asap. I will get back to you
later.

I guess my reporting was a bit too quick, sorry:
I'm running python 2.3.5, (installed from windows binary).
Zope 2.7.7 (not necessary for the test scripts)
Windows XP Home SP2 (blush - my laptop came with that... ;) )

Subject: [Zope] reportlab and images
Message-ID: <20050727134731.5928.qmail@web25603.mail.ukl.yahoo.com>

I know, I'm flooding the list ...
I use images inside my reports, so I have to open PIL-image objects inside my product.
Everything is fine, but I must use the full path, like /Zope-Instance/Products/foobar/image/blah.png, and this is a problem, because the product will have a different path when put in production.
My solution is to have a class variable to use, like:
 
  imagepath = "/Zope-Instance/.../image"
 
and then use that variable to build the path, but I think it's ugly.
How do you solve this problem and just use 'image/blah.png' just like ZPTs, knowing that all image files will be stored in an "image" subdirectory of the product ?
 
TIA,
  ngw

Cool!  If you can, posting a self-contained program that demonstrates
the problem is the best way to make progress.

> I guess my reporting was a bit too quick, sorry:

Not at all -- you did excellent detective work here!  It's
appreciated.  The problem is that English descriptions are nearly
always ambiguous, especially when trying to explain something
complicated that other people haven't reported.  Posting a program
removes all that guesswork:  it reproduces the problem for other
people on other boxes, or it doesn't, and we learn something valuable
either way; if it does fail for others, then they can help investigate
_why_ it fails.  At the start, thoroughly demonstrating a problem
exists is more important than guessing at what might be needed to worm
around it.

Good -- thanks.  A pretty vanilla system, then.  I've heard that XP
Home has "special" limitations on network capabilities, but don't know
more than that; it's at least possible they're relevant.  I'm not sure
that running multiple Zope instances on a laptop is a prime use case
for Zope <wink>.

is there any dtml codes that can display a file's type?
 
I made a site that allows a person to send up a document file. But in the end what I really wanted is to let people to upload .doc files. 
Since I didn't put any restriction on it, people always send up a smaller .pdf file instead.
 
So how do I encode my webpage to show the file type of the file that have already being uploaded??

All File objects have a content_type property.
Try 
<dtml-var "_['somefile.doc'].content_type">

Here's a code snippet from one of our applications (you should be able to figure out what you need from this example):

    <dtml-with UserData>
      <dtml-with "manage_addProduct['TCAide']">
        <dtml-with "TCAUsers.createInObjectManager(REQUEST['clientid'], REQUEST)">
          <dtml-call "propertysheets.TCAUsersPS.manage_changeProperties(REQUEST)">
          <dtml-call reindex_object>
        </dtml-with>
      </dtml-with>

UserData is a folder where new zclass instances are stored.
TCAUsers is our zclass
TCAUsersPS is the common instance propertysheet for the zclass
All of the property fields/values are stored in REQUEST (as a result of a user filling in an html form)
We call reindex_object because our zclasses are 'catalog aware' and we are reindexing the catalog.

If you're writing SQL queries attached to a Product and using them in 
said Product, you should look at ExtZSQL:

It was made for precisely this problem.

Subject: [Zope] what the namespace means in Script(python)?
Message-ID: <42E7C83C.5040702@gmail.com>

Hi list:

In Script(python) binding page. there is some description about 
namespace binding:

When the script is called from DTML, this is the caller's DTML 
namespace, otherwise it is an empty namespace.

Recommended value: |_| (underscore character)

But in zope book, when talk about  Error Handling in the Advanced Page 
Templates chapter. It looks that it use ZPT with script's namespace. See 
below.

For more flexible error handling you can call a script. For example:

<div tal:on-error="structure here/handleError">
...
</div>

Any error that occurs inside the |div| will call the |handleError| 
script. Note that the |structure| option allows the script to return 
HTML. Your error handling script can examine the error and take various 
actions depending on the error. Your script gets access to the error 
through the |error| variable in the namespace. For example:

## Script (Python) "handleError"
##bind namespace=_
##
error=_['error']
if error.type==ZeroDivisionError:
    return "<p>Can't divide by zero.</p>"
else:
    return """<p>An error occurred.</p>
              <p>Error type: %s</p>
              <p>Error value: %s</p>""" % (error.type,
                                           error.value)



So what happened with namespace when calling Script from ZPT?

Maybe, you should learn about "package_home".

You find it in "App.Common".

It is used in the form "package_home(globals())" and
returns the directory the current module is located in (provided
this module lies in a Python package or is one).

I think, a class variable "sqlFetchSomething" would do a better
job -- unless "SQL" depends on "conn".

Advantages:

  *  fewer objects in the ZODB, fewer loads, faster operations

  *  easier evolution of your SQL (in you need to change the
     SQL executed)

Subject: [Zope] ZSQLMethod conditional insert
Message-ID: <200507272022.25653.thomas@headnet.dk>

Hi

This is probably an FAQ but I haven't been able to find and answer.

I need a counter for a certain CMFType and want to store the hits in a MySQL 
database not to fill up the ZODB. I've checked to two suggestions below but 
they both use two ZSQLMethods first to check if the URL is already in the 
table, then to do the actual update or insert.

http://www.zope.org/Members/element/Simple_SQL_Page_Counter
http://zopelabs.com/cookbook/991116439

I'd like to be able to do that just in one ZSQLMethod for efficiency but I 
cant seem to figure out a way of doing it.

The table is very simple:

CREATE TABLE mostread (
  path varchar(255) NOT NULL default '',
  num bigint(20) NOT NULL default '0',
  dt datetime NOT NULL default '0000-00-00 00:00:00',
  PRIMARY KEY  (path)
)

For now my ZSQLMethod get the argument "path" which is a relative URL and it 
looks like this:

  select @lastval:=num from mostread where <dtml-sqltest path type="string">
  <dtml-var sql_delimiter>
  update mostread set num=@lastval+1, dt=now() where <dtml-sqltest path 
type="string">;
  </dtml-if>

But that naturally only works if there is already a record containing "path". 
What I want to do is something like this (pseudo-code):

  select @lastval:=num from mostread where <dtml-sqltest path type="string">
  <dtml-var sql_delimiter>
  <dtml-if "sequence-length > 0">
    update mostread set num=@lastval+1, dt=now() where <dtml-sqltest path 
type="string">;
  <dtml-else>
    insert into mostread(path, num, dt)
      values(<dtml-sqlvar path type="string">, 1, now())
  </dtml-if>

Is there a way of doing this or should I just create that extra ZSQLMethod?

More info on that:  since WinXP Pro supplies only about 4000 ephemeral
ports by default, and the program kept hanging after about 4000
ephemeral ports were in use (albeit most in their 4-minute TIME_WAIT
shutdown state), I tried boosting the # of ephemeral ports:

    http://support.microsoft.com/kb/q196271

After that, I never saw the processes hang again.  BUT, I saw
something worse:  after about 20 minutes, both processes died with
assert errors, in the code I added to verify that the sockets were
communicating correctly.  The random string created in process A was
actually read by a socket in process B (instead of by its pair in
process A), and vice versa:  the random string created in process B
was read in process A, and at approximately the same time process B
was reading process A's string.

I tried it again, and got a pair of similar assert failures after
about 15 minutes.

That's dreadful, and I don't see how it could be anything except a
race bug in the Windows socket implementation.

The same program on Linux doesn't run long enough to say anything
interesting -- it raises "BindError, 'Cannot bind trigger!'" very
quickly every time, because it apparently keeps server port numbers
(19999, 19998, ,,,) reserved for "a long time" after the server socket
is closed (where "a long time" just means longer than the few seconds
it takes for the program to die on Linux).

All of the above is wrt using socktest1() below.

socktest2() below contains the Windows code I already changed ZODB 3.4
to use.  I've been running socktest2() in two processes that way on
Windows for more than 2 hours now, with no glitches.  The same code is
running fine on a Linux box too.

So best guess now is that there is a subtle, rare error in the Windows
socket code that could cause the Medusa/ZODB3.2 Windows trigger code
to screw up.

Complete code:

import socket, errno
import time, random

class BindError(Exception):
    pass


def socktest1():
    """blabla
    """

    address = ('127.9.9.9', 19999)

    a = socket.socket (socket.AF_INET, socket.SOCK_STREAM)
    w = socket.socket (socket.AF_INET, socket.SOCK_STREAM)

    # set TCP_NODELAY to true to avoid buffering
    w.setsockopt(socket.IPPROTO_TCP, 1, 1)

    # tricky: get a pair of connected sockets
    host='127.0.0.1'
    port=19999

Subject: [Zope] Plone doesn't show up in the Zope Interface - ./runzope issue
Message-ID: <134b8b7105072712374c55d649@mail.gmail.com>

Hello

This is my first experience of unix installs from source and I need a
small amount of help to finish off my installation.

I've installed Zope and Python from source, remotely, onto a RedHat
box and am able to access the browser based ZMI admin screen remotely.
I've followed the following instructions for getting Plone up and
running but on stopping and starting the zope instance, Plone isn't
available. I've tried stopping the service using the ZMI and
restarting using telnet.

       1. Download Plone 2 from http://www.plone.org/download, and
select the tarball file.
       2. Unzip the archive using the following: tar xzf CMFPlone2.0.tar.gz
       3. You'll find that a directory has been created called
CMFPlone-xxx, where xxx is the version (for example, CMFPlone-2.0).
       4. Move the contents of that directory into your Zope
installation's Product directory. For example, if the Zope Products
directory is in /var/zope, then do this: mv CMFPlone2.0/
/var/zope/Products*

The zope products directory is /home/zopeinstance/Products/ which
lists Plone-2.0.5

I also have an issue where running /home/zopeinstance/bin/runzope

using ./runzope as the zopeinstance user

starts the service but the Unix prompt just hangs and doesn't do
anything. I am able to get the browser management screen but on
exiting the telnet session the service stops.

Would anyone have any ideas at all?

By the way ./start_zope
and ./stop_zope
from the core /zopeinstance directory don't seem to work.

Thanks for any help

Hi

This isn't clear to me. I've installed Zope and Python from source but
do I need to also install the Zope CMF for Plone to run properly? This
isn't mentioned specifically any where if so.

It would good to have some of these components wrapped up etc for
easier install. I couldn't find the RPM's on the site.

Yes, it does (heavily).

CMF is mandatory is  likely documented somewhere as requirement.

Hi!

I think it's not really a discussion about Open Source here as it should
make no difference to the Zope community whether ZC or ZEA is holding
the TM. Both don't represent it and both possibly could do harm to it if
they just wanted to (which they don't want as I see it).

I think it's more a story about a company which some time ago made their
software open source. The result of that was a big win for the Zope
project as it attracted a lot of developers and, as a result, created a
lot of additional projects like Silva, Plone, CPS etc. So now we have
quite a big community advocating the use of Zope and now also doing the
main development of the software itself (in form of Zope3).
I am part of that community and I am proud of that :-)
So from Zope having it's roots in that company these problems arise IMHO.

So having said that I am a bit disappointed by the recent discussions
here as it's maybe the sign of some unresolved problems between certain
important players in the Zope world.

Some points:

- How the thread was started by ZC was IMHO not really good style. For
  me it sounded like very hard words and threatening with not doing the
  foundation did not sound too good and not really a good thing for the
  community. I also still don't understand what the foundation has to do
  with the actual TM discussion - wasn't it just the logo about which
  was being discussed?
  So what would have happened in the case if not ZEA did register it but
  any evil guy?
  To hold the creation of the Foundation should not have been the answer
  in any case!

- if ZEA has registered the TM without telling ZC this is of course not
  ok. I understand if you don't discuss it loudly so that other parties
  hurry to register it but it could have been solved easily back then
  with a silent negotiation between the two parties.
  (too bad ZC did not simply register everything themselves so we would
  have one discussion less)

- in general: Bashing each other will not help Zope and not the
  community. And a damaged community cannot help ZC or ZEA or any other
  player in the Zope world. So it should be in everyones interest to
  keep things going in a good mood.


So that much about the form now more about my worries about the TM
itself. Legally of course ZC is the right owner of the TMs as they
created Zope. But OTOH it would feel more right if the TM would be
transferred to the Zope Foundation. ZC once opensourced their project
and the main work in terms of coding and marketing seems to be done by
the community now and less and less by ZC (at least it seems to
me that way). And for me Zope also feels like an open source project
through and through and not something belonging to some single company.
>From what I see that's also the way most of the rest of the world thinks
about it, especially in Europe. Thus for me it would just feel better if
also the TM would be given to the community in form of the foundation
(as "the community" is no real legal person the foundation might be the
next possible thing).

I also read about the irrevocable license given to the Zope Foundation
and it might make no difference legally for the TM whether ZC or the ZF
owns it. But as said before, I am no legal expert and thus I don't know
about all the impacts and thus I am worried. So also because of this it
would feel better for me if the TM would be owned by the ZF as there are
just more checks&balances between their members than there will be with
a single player. And hopefully I would at least trust one of them ;-)

But maybe somebody can answer me some questions about it anyway:

1. What does the license mean. Does it mean that ZF will also have the
   right to decide who is allowed what to do with the TM, and even
   restrict ZC?

2. If ZC might get evil (I don't assume that, btw :-): What might happen
   with sites like zopelabs or any other site/institution having "Zope"
   in it's name. Can they tell them to remove that name?

3. What will happen in this worst case if ZC (or more exactly evil ZC)
   will suddenly start doing a Java CMS under the name "Zope"? Can the
   ZF prevent this?

So basically it's not quite clear to me if the license just means that
ZF is allowed to use the name or if they also can really protect it.
There might always be the possibility to rename the whole project but
why should I advocate Zope now if this investment might be lost someday?

So because of this discussion I am a bit worried. It might be called
"irrational fears" but I might not be the only one and as many in the
community are not fluent in legal things this stuff should be thought
about very carefully in order to keep the environment intact as this is
what Zope makes alive.
(OTOH the community seems not really taking part in that discussion so
maybe it's just me who is a bit worried ;-)

Finally I would like to ask all arguing parties, like ZF and ZEA (and
after reading their blog maybe also Nuxeo) to get together and get
things get sorted out between them. I hope there's a will to do it.
Otherwise the often repeated phrase "we are all in one boat" etc. sounds
a bit strange.. The climate could at least be better..

regards,

Christian

Hi Thomas. I would say postgres is better for this sort of thing.  In 
postgres, you can write a function in plpgsql or other function 
language (there is also a python function language) that you install in 
postgres. In any case once you write it and then call it - it is 
executed in a single transaction.  You are only left with selecting the 
function in your zsql from your script. It is hard to comment on the 
method you have sketched out not knowing what arguments you are passing 
into the method. You have identified path but I see others that you 
haven't discussed so don't really know where you plan on getting them 
from.

Regards,
David

I would prefer postgres too but it is decided to use MySQL in the project...

Well "path" is actually the only argument passed to the method. "select 
@lastval:=num" is a (I think) MySQL specific way of assigning values to local 
variables. I could probably use a sub-select or something but my SQL is a bit 
rusty ;-)

Hi!

Might something like this help?

INSERT INTO table (a,b,c) VALUES (1,2,3)
       ON DUPLICATE KEY UPDATE c=c+1;

So this will catch errors and instead do the update.
Available from version 4.1.0 on as the docs say.

See also the docs:

Fernando:

I have downloaded the source from 

           http://initd.org/pub/software/psycopg/PSYCOPG-1-1/

and compiled it (in RH FC4 and RHEL3, tough)  with no problams
whatsoever. 

I am using Zope 2.7.5, Python 2.3.5, Psycopg sources 1.1.19 and
PostgreSQL 8.0.3 

The only advice would be to upgrade your postgresql to 8.0.3 since the
version you are using is a bit outdated.

Best regards.

Could you please tell us *which error*? The people in charge for fixing 
such issues need some more useful information that "the same error".

Subject: [Zope] Zope 2.8.1 beta 1 released
Message-ID: <C20BAADCE1C37408DFDD8DC0@vg180472xppro>


Hi all,

on behalf of Zope Corporation and the Zope community I am pleased to 
announce the release of Zope 2.8.1b1.  You can download Zope 2.8.1b1 from

      http://www.zope.org/Products/Zope/2.8.1b1/

Some new features of Zope 2.8:

   - ZODB 3.4 with MVCC (multi version concurrency control) support.
     MVCC solves nearly every problem with ZODB read-conflict errors
     which is very important for high-traffic Zope sites.

   - Extension Classes were rewritten as Python new-style classes making
     all features of Python new-style classes available in Zope
     objects. This includes support for cyclic garbage collection.

   - Integration of Zope 3 technologies through Five (see 
http://codespeak.net/z3/five/)


For more information on what is new in this release, see the
CHANGES.txt files for the release:

  http://www.zope.org/Products/Zope/2.8.1b1/CHANGES.txt

Message-ID: <1f7befae050727223844dea123@mail.gmail.com>

It's starting to look a lot like the Windows bind() implementation is
unreliable, sometimes (but rarely -- hard to provoke) allowing two
sockets to bind to the same (address, port) pair simultaneously,
instead of raising 'Address already in use' for one of them.  Disaster
ensues.

WRT the last version of the code I posted, on another XP Pro SP2
machine (again after playing registry games to boost the number of
ephemeral ports) I eventually saw all of:  hangs during accept(); the
assertion errors I mentioned last time; and mystery "Connection
refused" errors during connect().

The variant of the code below _only_ tries to use port 19999.  If it
can't bind to that on the first try, socktest111() raises an exception
instead of trying again (or trying a different port number).  Ran two
processes.  After about 15 minutes, both died with assert errors at
about the same time (identical, so far as I could tell by eyeball):

Process A:

Traceback (most recent call last):
  File "socktest.py", line 209, in ?
    assert msg == msg2, (msg, msg2, r.getsockname(), w.getsockname())
AssertionError: ('292739', '821744', ('127.0.0.1', 19999), ('127.0.0.1', 3845))

Process B:

Traceback (most recent call last):
  File "socktest.py", line 209, in ?
    assert msg == msg2, (msg, msg2, r.getsockname(), w.getsockname())
AssertionError: ('821744', '292739', ('127.0.0.1', 19999), ('127.0.0.1', 3846))

So it's again the business where each process is recv'ing the random
string intended to be recv'ed by a socket in the other process. 
Hypothesized timeline:

process A's `a` binds to 19999
process B's `a` binds to 19999 -- according to me, this should be impossible
    in the absence of SO_REUSEADDR (which acts very differently on
    Windows than it does on Linux, BTW -- on Linux this should be impossible
    even in the presence of SO_REUSEADDR; regardless, we're not using
    SO_REUSEADDR here, and the braindead hard-coded

        w.setsockopt(socket.IPPROTO_TCP, 1, 1)

    is actually using the right magic constant for TCP_NODELAY on
    Windows, as it intends).
A and B both listen()
A connect()s, and accidentally gets on B.a's accept queue
B connect()s, and accidentally gets on A.a's accept queue
the rest follows inexorably

Note that because this never tries a port number other than 19999, it
can't be a bulletproof workaround simply to hold on to the `a` socket.
 If the hypothesized timeline above is right, bind() can't be trusted
on Windows in any situation where two processes may try to bind to the
same hostname:port pair at the same time.  Holding on to `a`, and
cycling through port numbers when bind() failed, would still
potentially leave two processes trying to bind to the same port number
simultaneously (just a port other than 19999).

Ick:  this happens under Pythons 2.3.5 (MSVC 6) and 2.4.1 (MSVC 7.1),
so if it is -- as is looking more and more likely --an error in MS's
socket implementation, it isn't avoided by switching to a newer MS C
library.

Frankly, I don't see a sane way to worm around this -- it's difficult
for application code to worm around what smells like a missing
critical section in system code.

Using the simpler socket dance from the ZODB 3.4 code, I haven't yet
seen an instance of the assert failure, or a hang.  However, let two
processes run that long enough simultaneously, and it always (so far)
eventually fails with

    socket.error: (10048, 'Address already in use')

in the w.connect() call, and despite that Windows picks the port numbers here!

While that also smells to heaven of a missing critical section in the
Windows socket implementation, an exception is much easier to live
with / worm around.  Alas, we don't have the MS source code, and I
don't have time to try disassembling / reverse-engineering the opcodes
(what EULA <wink>?), so best I can do is run this for many more hours
to try to increase confidence that an exception is the worst that can
occur under the ZODB 3.4 spelling.

Here's full code for the "only try port 19999" version:

import socket, errno
import time, random
def socktest111():
    """Raise an exception if we can't get 19999.
    """

    a = socket.socket (socket.AF_INET, socket.SOCK_STREAM)
    w = socket.socket (socket.AF_INET, socket.SOCK_STREAM)

    # set TCP_NODELAY to true to avoid buffering
    w.setsockopt(socket.IPPROTO_TCP, 1, 1)

    # tricky: get a pair of connected sockets
    host = '127.0.0.1'
    port = 19999

    try:
        a.bind((host, port))
    except:
        raise RuntimeError
    else:
        print 'b',

    a.listen (1)
    w.setblocking (0)
    try:
        w.connect ((host, port))
    except:
        pass
    print 'c',
    r, addr = a.accept()
    print 'a',
    a.close()
    print 'c',
    w.setblocking (1)

    return (r, w)

sofar = []
try:
   while 1:
       try:
           stuff = socktest111()
       except RuntimeError:
           print 'x',
           time.sleep(random.random()/10)
           continue
       sofar.append(stuff)
       time.sleep(random.random()/10)
       if len(sofar) == 50:
           tup = sofar.pop(0)
           r, w = tup
           msg = str(random.randrange(1000000))
           w.send(msg)
           msg2 = r.recv(100)
           assert msg == msg2, (msg, msg2, r.getsockname(), w.getsockname())

Hi,

I have a doubt...

I would like to know if all the fixes included in Zope 2.7.7 (that was out
after 2.8.0) will be included in 2.8.1, like for example :
* Collector #1781: made create_mount_points ZConfig option actually work
(thanks to Dieter Maurer for the patch). 
* Collector #1797: when a File/Image object returned a "304" response code
in response to an If-Modified-Since request, it did not collaborate with any
cache managers. It used to, and it has been changed back to do so. Thanks to
d2m and Bertrand Croq. 

More generally, what will be the relationship between new Zope 2.7.x
versions fixes (will there be new versions ?) and Zope 2.8.x fixes ?

Thanks.

Pascal

You can check this yourself by reading doc/CHANGES.txt

2.7 and 2.8 are the current maintained Zope versions. Fixes should be made 
for both versions.

You can check this yourself by reading doc/CHANGES.txt

2.7 and 2.8 are the current maintained Zope versions. Fixes should be made for both versions

Subject: [Zope] Split a ZODB
Message-ID: <42E89574.90702@alfa.it>

Hi!

 How can I split a Zodb? I mean, I have a big folder which I would like 
to became a separate ZODB file to mount on the main one. In unix I would 
move all the files of that folder on another partition, then mount it on 
that folder.

Good day everyone

I've defined some archetypes that contain fields like Title_en, Title_de, 
Content_en, Content_de, etc.
Assuming that I've set a language var related to URL like (lang = 'en'), how 
can i access them?

Thanks,

Hi Christian,

Thanks for this long and balanced post.

Far less heated than I (or other hot people of the community) can produce.

I hope ZC will take time to answer your legitimate questions...

I suppose you'll await some progress on the negotiation before joining 
us in ZEA...

BTW, do you have the feeling ZEA was trying to steal anything, have you 
heard of others that would think we tried to ?

At least I agree ZEA should have communicated with ZC far earlier.

Please ask AT related questions on the at-users list. In general you should 
not access attributes in AT directly but only through the accessor methods.
There is something like getField(fieldname) in the AT which might help you
(look also at the AT docs).

Message-ID: <bc95c28005072802594f5ea377@mail.gmail.com>

I would like to be able to parse a very basic DTML string (a
ZSQLMethod on the file system actually) outside Zope, ie. without
having the whole zserver running.
The DTML inside the string is very basic. It doesn't use REQUEST or
aqcuisition. It's using <dtml-if "1==2"> and stuff.
I've tried looking on the source code but it's so damn complicated for
me. Can anybody give me a headstart on this?

Good!

 Anyway, some command line tools could help... zodb operations can take 
longer time (for example, changing the name of the upper folder wake up 
all the "contained" objects...)

Yeah, but it wouldn't be faster through the command line...

If you are trying to access the zodb without having zope running, here are a 
couple of ways to make it happen:

# method #1
import os, sys, traceback
sys.path.append("/apps/zope/lib/python")
import Zope
app=Zope.app()
from Testing import makerequest
app = makerequest.makerequest(app)


# method #2
import os, sys
sys.path.append("/apps/zope/lib/python")
import Zope
import time
app=Zope.app()


Once you have 'app' you can do things like:

REQUEST = app.REQUEST
newobj = 
app.Wet.Content.Data.manage_addProduct['myProd'].manage_addmyItem(...)
app.unrestrictedTraverse('Control_Panel/Database/ShopwiserData').manage_pack()

No. I've actually found a way to do it without starting zope (thus,
not using the ZODB).
The trick was in import nvSQL from DA.py and use that. It works now, I
can now parse and run ZSQL methods on the filesystem without having
any zope running.
I'm going to tidy my script and post it on my blog soon.

Subject: [Zope] strange getPhysicalRoot behaviour
Message-ID: <1122549877.42e8c0754ac44@webmail.nederhoed.com>

Good day all,


Using Zope 2.7.6 I'm trying to use the getPhysicalRoot() function.

In a rather large site we have a folder called 'functions' placed in root. This
folder contains a formatting function 'far' I want to use in some other folder.
But in the path from root to the place I the function to be called, I have
another 'function' folder, with local functionality.

When calling 'context.functions.far()', it fails to acquire the far function.
Which is explainable.

My plan was to call it directly: 'root.functions.far()', but 'root' does not
exist in the zope (python) script.

if I use
root = context.getPhysicalRoot()

I am forced to reenter my Zope username and password and will not get permission
to call the getPhysicalRoot function.

What am I doing wrong?
What can I do to make the getPhysicalRoot function available?


Friendly greetings,



Robert-Reinder Nederhoed

Looks like the method is restricted. VerboseSecurity will tell you why.

But how do I get the connection id ?
Actually I get it when I instance the product in Zope.
What I think is something like
 
class Foo
 
  def __init__ (self, conn):
    self.conn = conn
 
  myquery = SQL ('doMyQuery', '', self.conn, '', 'select * from table')
 
but obviously it will not work.
 
TIA,

p.s. Sorry for top-posting

Marco Bizzarri <m.bizzarri@icube.it> ha scritto: 
I can't talk for best practise. You can put your queries also outside of
the init, in this way:

class YourProduct:

_my_query = SQL('doMyQuery', '',
'your_connection', '', 'select * from data')

def __init__(self):
pass


Also, if you have a *LOT* of queries, consider in building your query on
the fly.

Hi,
 
I would like to know what if using taskset (CPU affinity utility on linux)
to bind each Zope instance to one single CPU can improve overall performance
of both instances in any way ?
 
As far a I know, python can not fully take advantage of 2 CPU cause python
threads are not OS threads.
 
Thanks.

This is what I'm experiencing as well.
I can narrow it down a bit: I *always* experience one out of two
erroneous behaviours, as described below.

I tried to make an even simpler test situation, without binding
sockets 'r' and 'w' to each other in the same process. I try to
reproduce the problem in a 'standard' socket use case, where a client
in one process binds to a server in another process.

The following two scripts acts as a server and a client.

#***********************
# sock_server_reader.py
#***********************
import socket

a = socket.socket (socket.AF_INET, socket.SOCK_STREAM)

a.bind(("127.0.0.1", 19999))
print a.getsockname()  # assigned (host, port) pair

a.listen(1)

print "a accepting:"
r, addr = a.accept()  # r becomes asyncore's (self.)socket
print "a accepted: "
print ' ' + str(r.getsockname()) + ', peer=' + str(r.getpeername())

a.close()

msg = r.recv(100)
print 'msg recieved:', msg


#***********************
# sock_client_writer.py
#***********************
import socket, random

w = socket.socket (socket.AF_INET, socket.SOCK_STREAM)
w.setsockopt(socket.IPPROTO_TCP, 1, 1)

print 'w connecting:'
w.connect(('127.0.0.1', 19999))
print 'w connected:'
print w.getsockname()
print ' ' + str(w.getsockname()) + ', peer=' + str(w.getpeername())
msg = str(random.randrange(1000000))
print 'sending msg: ', msg
w.send(msg)




There are two possible outcomes [a) and b)] of running two instances
of this client/server pair (that is, 4 processes in total like the
following).
(Numbers 1 to 4 are steps executed in chronological order.)

1) python -i sock_server_reader.py
The server prints:
	('127.0.0.1', 19999)
	a accepting:
and waits for a connection

2) python -i sock_client_writer.py
The client prints:
	w connecting:
	w connected:
	('127.0.0.1', 3774)
	 ('127.0.0.1', 3774), peer=('127.0.0.1', 19999)
	sending msg:  903848
	>>>

and the server now accepts the connection and prints:
	a accepted:
	 ('127.0.0.1', 19999), peer=('127.0.0.1', 3774)
	msg recieved: 903848
	>>>

This is like it should be. Then lets try to setup a second
client/server pair, on the same port (19999). The expected outcome of
this is that the bind() call in sock_server_reader.py should fail with
socket.error: (10048, 'Address already in use').

3) python -i sock_server_reader.py
The server prints:
	('127.0.0.1', 19999)
	a accepting:

Already here the problem occurs, bind() is allowed to bind to a port
that is in use, in this case by the client socket 'r'.
[also on other windows ? Mikkel: yes. Diku:???]

4) python -i sock_client_writer.py
Now one out of two things happen:

a) The client prints:
	w connecting:
	Traceback (most recent call last):
	  File "c:\pyscripts\sock_client_writer.py", line 7, in ?
	    w.connect(('127.0.0.1', 19999))
	  File "<string>", line 1, in connect
	socket.error: (10061, 'Connection refused')
	>>>
    The server waits on the call to accept(), still waiting for a
connection. (This is the blocking behaviour I reported in my first
mail, experienced when running two zope instances. The socket error
was swallowed by the unconditional except clause).

b) The client connects to the server:
	w connecting:
	w connected:
	('127.0.0.1', 3865)
	 ('127.0.0.1', 3865), peer=('127.0.0.1', 19999)
	sending msg:  119105
	>>>

and the server now accepts the connection and prints:
	a accepted:
	 ('127.0.0.1', 19999), peer=('127.0.0.1', 3865)
	msg recieved: 119105
	>>>

The second set of client/server processes are now connected on the
same port as the first set of client/server processes. In a port
scanner the port now belongs two the second server process [3)].


I always get one out of these two possibilities (a and b), I never
see bind() raising socket.error: (10048, 'Address already in use').

It is important to realize that both these outcomes are an error.

I tried the same process as above on a linux system, and 3) always
raises (10048, 'Address already in use').


If case a) occured, where w.connect raises socket.error: (10061,
'Connection refused'), trying to run a third client/server pair, the
bind() call raises (10048, 'Address already in use'). The 'a'-socket
from the second pair of processes is not closed in this case, but
still trying to accept().

In my case bind() always raises (10048, 'Address already in use') when
there is an open server socket like 'a' bound to the same port.

To summarize:
Closing a server socket bound to a given port, alows another server
socket to bind to the same port, even when there are open client
sockets bound to the port.

It would not be enough to keep a reference to 'a'. It would have to be
kept open as well. And maybe that is not a problem, since we only
accept() once - only one 'w' client socket would be able to be
accepted. Normally the use case for closing the server socket is to
disallow more connections than those already acceptet.
(But I'm not so experienced with sockets, I might be wrong.)

That is exactly what I feared could happen. As shown in my example
above, the other that might happen is that the port is 'taken over' by
the other process.

I consider it very usefull, and I can see nothing that should cause problems 
with that (well, except from the problem mentioned i this thread). Of course, I 
do not use the laptop as server - but for development purposes. I have around 
10-15 instances for varoius projects, quite often with 2 or 3 instances running 
at the same time.

The cost you save is the cost of processes and thread switching  
between CPUs, which may happen depending on the OS and kernel versions.

A single Python CPU can not be run on multiple CPUs. It will use only one.
Consider using ZEO on multiple CPU machine with one storage process and 
multiple ZEO clients.

Run as many Zope instances as CPUs you have if you wish to take advantage of
this in Zope:  i.e. 2 CPUs == 2 Zope Instances.

You will basically double the performance of the server with ea.
CPU/Instance.  At some point there might be a diminishing return, but I
doubt any of us have that kind of hardware :-)

Hi,

 

I would like to know what if using taskset (CPU affinity utility on linux)
to bind each Zope instance to one single CPU can improve overall performance
of both instances in any way ?

 

As far a I know, python can not fully take advantage of 2 CPU cause python
threads are not OS threads.

 

Thanks.

I have made two similar testprograms in c++, and the problem also occurs there. 
Exactly the same pattern as my python client/server scripts in the mail I am 
replying to.

But then I stumbled upon this flag in the WinSock documentation: SO_EXCLUSIVEADDRUSE
See the description here:
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/winsock/winsock/using_so_exclusiveaddruse.asp

It is very interesting reading, especially:
"An important caveat to using the SO_EXCLUSIVEADDRUSE option exists: If one or 
more connections originating from (or accepted on) a port bound with 
SO_EXCLUSIVEADDRUSE is active, all bind attempts to that port will fail."

This is just what we want (and I think that is standard behaviour on Linux).

I have tested it with my c+ programs, and when i set that option on the server 
socket before the bind(), it works, bind() in the second server process fails 
with WSAEADDRINUSE
(bind() failed: 10048.)

There is a python bugfix for this, but only for python 2.4:
http://sourceforge.net/tracker/index.php?func=detail&aid=982665&group_id=5470&atid=305470
(It is added to version 1.294 of socketmodule.c)


I run the two test programs from two cmd terminals, like I described for the 
python versions.

For unknown reasons, "getPhysicalRoot" is private.

The standard workaround looks like this:

    root = container.restrictedTraverse('/')


Of course, it is stupid to make "getPhysicalRoot" private
when it is so easy to access the root anyway...

ZPT's are ready to expose its namespace as if it were
a DTML namespace.

Therefore, you can also pass a ZTP namespace to the "namespace"
binding of a Python Script.

Solved.


Thanks for the reactions. It works! My current code looks like this now:

#force function in '/root/functions'
far = context.restrictedTraverse('/').functions.far

x = foo()
print far(value=x)

Why not just add 'root' to the script vocabulary?

I'd also prefer some answers by some independant people regarding legal
topics (as long as it can be told based on the facts).

Well, it was explained to me what ZEA is at EP and I was just listening
for now ;-) The same is true for the ZF.

> BTW, do you have the feeling ZEA was trying to steal anything, have you

Well, I cannot look into the heads of people but in general I trust
people so when ZEA says they just wanted to protect it, I believe it as
I believe that ZC has no evil plans with the TM. I think trying to steal
it wouldn't be a good idea anyway and I think that the people at ZEA
know this as the publicity of this would be against them (as we see
now). Moreover I know some people at ZEA and they seem to be nice guys
anyway and not "business sharks".
Actually it feels a bit like a competition issue between ZC and ZEA and
it would be nice if this would be sorted out between them (internally
please) as the market is big enough (especially if one party is in the
US and the other one in Europe).

So about this whole topic actually there are two points:

1. How the issue was handled. IMHO not good on both sides.

2. What the plans with the TM are and what they mean to the Zope community.

> At least I agree ZEA should have communicated with ZC far earlier.

Good :-)

If I recall, Casey Duncan suggested putting a python script in *root* 
named ROOT, e.g.

#module ROOT
return container

This is aquirable from anywhere else in Zope and is easy to remember.

I see only one of the behaviors below (the second -- no problems), and

Note that

    a = socket.socket()

is an easier way to spell the same thing; the Medusa code is ancient.

Key point:  no socket is _listening_ on address ("127.0.0.1", 19999)
after this close().  From what comes later, I guess you believe that
no socket should be allowed to listen on that address again until all
connections made with that `a` also close, but I don't think you'll
find anything in socket documentation to support that belief.  In the
world of socket connections, what needs to be unique is _the
connection_, and that's a 4-tuple:

    (side 1 host, side 1 port, side 2 host, side 2 port)

There's no prohibition against seeing either side's address in any
number of connections simultaneously, you just can't have two
connections simultaneouly that match in all 4 positions.  It so
happens that Windows is happy to allow another socket to bind to a
port the instant after a socket that had been listening on it closes
(and regardless of whether connections made via the latter are still
open), but I don't believe that's a bug.

What I appear to be seeing is that sometimes-- rarely --Windows allows
binding to a port by two sockets simultaneously, not serially as
you're showing here.  Simultaneous binding (in the absence of
SO_REUSEADDR on Windows) is a bug.

Sorry, I don't expect that.  sock_server_reader is no longer listening
on port 19999, so there's no reason some other socket can't start
listening on it.

I showed an example before of how you can get any number (well, up to
64K) of sockets simultaneously alive saying they're bound to the same
address, on Windows or Linux.  The socket returned by a.accept()
always duplicates a's (hosthame, port) address.  That's so that if the
peer asks for its peer, it gets back the address it originally
connected to.  It may be confusing, but that's how it works.

Windows and Linux seem to differ in how willing they are to reuse a
port after a listening socket is closed, but dollars to doughnuts says
Microsoft wouldn't accept a claim that their behavior is "a bug".

How often do you see this?  I haven't seen it yet, but I can't make
hours today to do this hand.

The real reason (and well-hidden it is) the Medusa code puts its
connect() call in try/except is because the Medusa code (but not your
code here) set w to non-blocking mode before the connect, and
w.connect() on a non-blocking socket is always exceptional ("in
progress" on Linux, "would block" on Windows).  I have no idea why the
Medusa code set w to be non-blocking to begin with, and although I
haven't mentioned it here before, I saw all the same symptoms when I
removed the non-blocking convolutions.

This is the outcome I've seen every time I've tried it by hand -- no problems.

You can get to a similar end more easily by having a server socket
accept more than one connection -- all accept()'ed connections have
the same socket address.  The connection 4-tuples all differ, though,
and that's what matters.

If you can type very, very quickly <wink>, you should see that on
Windows if you manage to try binding to 19999 before the original
a.close() manages to complete.

> It is important to realize that both these outcomes are an error.

If it were true that outcome #b were in error, Windows would have a
trivially easy-to-reproduce gross bug here, of many years' standing 
Life's rarely that simple, alas.

Same here, but I've found nothing in socket docs requiring this
behavior, and, indeed, there doesn't appear to be a _logical_
necessity for it.  It's in fact somewhat of a pain on Linux, becuase I
continue to get 'Address already in use' even after I close both ends
of the socket connection too, presumably waiting for the 4-minute
TIME_WAIT shutdown dance to end.

...

That's as it should be.  Alas, what I believe the program I sent last
night shows is that Windows doesn't _always_ raise 'Address already in
use' when two server sockets are binding to the same port
simultaneously.  Instead it sometimes says "OK, you got it" to _both_
of them.  This is seriously difficult for me to provoke, BTW:  10-60
minutes per failure, on a 3.4 GHz hyperthreaded box.

And in Windows, I believe that's by design.  Indeed, I expect the
Medusa Windows code tries such a small number of ports (no more than
about 50) precisely because Windows has always allowed reusing a
listening port so quickly.  Otherwise the code would need to try at
least as many ports as "the maximum" number of triggers that could
possibly be open simultaneously -- but there's no way to know what the
maximum is, and it's expensive to try binding to a large number of
ports.  It would have to impose an artificial limit.

The Medusa Linux code avoids all of this by creating pipes instead;
alas, Windows asyncore.py can't work with Windows pipes.

Subject: [Zope] Suppressing dupes in a concatenated ZCatalog query.
Message-ID: <1122584265.27283.239470608@webmail.messagingengine.com>

Hi All,

I have a ZCatalog with two text indexes, news_subj and news_text. Each
ZCatalog item also has a unique numeric ID.

I'd like to search news_subj and news_text simultaneously, with the
results checked for duplicates. In other words, if catalog item 1001 has
the word "foobar" in both the news_subj and news_text fields, I only
want it to show up once in my search results.

Here's what I've got, so far:

<dtml-in expr="mp_catalog({'news_text':'foobar'}) +
mp_catalog({'news_subj':'foobar'})">
    <dtml-var news_subj><br>
</dtml-in>

This correctly searches both fields, but, when "foobar" appears in both
news_subj and news_text, the result is displayed twice.

Can anyone give me a pointer on suppressing dupes in a concatenated
ZCatalog query? I'm sure there's an easy answer, but I haven't been able
to find it.

Thanks in advance,
Aaron

I don't know if you can do that with ZCatalog alone.  Try Dieter's
AdvancedQuery product, it's been very helpful to me.

I had saved the following extract from a previous message on this mailing 
list, it may be of some help:

<snip>
finally I got it working and maybe it helps someone else ..
you can't necessarily eliminate duplicates from the ZCatalog search results 
by sorting the mybrains because the same object
 in the ZODB may be denoted my two different mybrains as far as I 
understand. so my "solution" was to make the absolute
 URLs the keys of a dictionary and return the values(), i.e. the mybrains:
PythonMethod "uniq" (parameter "items" contains the results of a Catalog 
query):
d = {}
 for item in items:
   url = item.getURL()
   d.update( { url: item } )
 return d.values()

 you can call it like that:
<dtml-let resa="Catalog(text_obj=begriff)"
   resb="Catalog(abstract_obj=begriff)"
   resc="Catalog(title=begriff)"
   res="resa[:_.len(resa)] + resb[:_.len(resb)] + resc[:_.len(resc)]">
 <dtml-in "uniq(items=res)" size=50 start=query_start> ....

</snip>

This is not a very elegant solution and will be cpu intensive, but if your 
catalog is not too large it may work for you.

Right, I vaguely <wink> knew about that.  Note that the documentation
explicitly states that in the absence of SO_EXCLUSIVEADDRUSE,

    the port may be reused as soon as the socket on which bind was called
    (that is, the socket the connection was originated on or the listening
    socket) is closed.

IOW, that's your "case #b" from earlier email, and Windows is just
doing what's documented there.  Believe it or not, I haven't found any
Linux-ish docs as clear as these MS docs about the behavior of its
bind() in all cases.

There are problems with SO_EXCLUSIVEADDRUSE too, which Google will
find.  A big one is that many versions of Windows require admin privs
to set this option, including many versions of Windows Server, and
WinXP through SP1.  That was a bug, but it's only recently been fixed
(in SP2 for WinXP).

At this point, I wouldn't consider using it unless someone first took
the tedious time it needs to demonstrate that when it is used, the
thing that _I_ think is a bug here goes away in its presence:  the
seeming ability of Windows to sometimes permit more than one socket to
bind to the same address simultaneously (not serially -- Windows does
seem to prevent that reliably).

If you can, I would like you to try the ZODB 3.4 Windows socket dance
code, and see if it works for you in practice.  I know it's not
bulletproof, but it's portable across all flavors of Windows and is
much better-behaved in my tests so far than the Medusa Windows socket
dance.

Note too that they describe that as an "important caveat" (a warning),
not as "a feature".  They go on to explain that "active" means all of
the ESTABLISHED, FIN_WAIT, FIN_WAIT_2, and LAST_ACK states, meaning
the port stays tied up (in reality) for minutes even after the `r` and
`w` sockets are closed.  That's a 50% increase then in the # of ports
each trigger tiies up for an arbitrarily long time.

...

That's not a real problem; if needed this could easily be done under
Python 2.3.5 too (the patch only adds a symbolic name for a fixed
integer; the integer could be hard-coded when not hasattr(socket,
"SO_EXCLUSIVEADDRUSE") -- much as the current Medusa dance hardcodes 1
instead of using socket.TCP_NODELAY).

I started, but didn't get that far.  The first time I ran a pair of
processes with the attached (Python 2.4.1, WinXP Pro SP2), one fell
over with

...
    w.connect((host, port))
  File "<string>", line 1, in connect
socket.error: (10048, 'Address already in use')

after about 20 minutes.

So, on the face of it, playing with SO_EXCLUSIVEADDRUSE is no better
than the ZODB 3.4 Windows socket dance.  Both appear mounds
better-behaved than the Medusa Windows socket dance without
SO_EXCLUSIVEADDRUSE, though.  Since there are fewer other problems
associated with the ZODB 3.4 version (see last email), I'd like to
repeat this part:

Bulletproof appears impossible due to what still look like race bugs
in the Windows socket implementation.

Here's the code.  Note that it changed to try (no more than) 10,000

    a.setsockopt(socket.SOL_SOCKET, socket.SO_EXCLUSIVEADDRUSE, 1)
    # set TCP_NODELAY to true to avoid buffering
    w.setsockopt(socket.IPPROTO_TCP, 1, 1)
    # tricky: get a pair of connected sockets

Subject: [Zope] Emergency user not working?
Message-ID: <27660f6a050728203674958af6@mail.gmail.com>

Hi I have zope-2.7.2 installed but I can't seem to log into zope with
the emergency user. I followed the instruction:
cd /usr/lib/zope
bin/zpasswd.py access
Username: superuser
Password:
Verify password:

Please choose a format from:

SHA - SHA-1 hashed password (default)
CRYPT - UNIX-style crypt password
CLEARTEXT - no protection

Encoding:
Domain restrictions:

and then I did /etc/init.d/zope restart but I still cannot log into zope. 

Am I doing anything wrong here?
Thank you

Are you sure you  that /usr/lib/zope is your instance home and *not* your 
software home? Double check if there is 'var' folder and var/Data.fs.
If you not then you're at the wrong place.

Andreas,
 You are awesome. :) It fixed the problem. Yeah, it should have been
/var/lib/zope. Thank you! Thank you! :) You just beat all the google
search I've done in the past hour. :)

Hi,
 
Concerning the zserver-threads config param...
If I have an http-server, ftp-server and webdqv-source-server and if my
global zserver-threads param is set to 10, does it mean :
a)The the max number of http-server + ftp-server + webdav-source-server
threads will be 10 ?
b)The max number of http-server + ftp-server + webdav-source-server threads
will be 30 (3 zservers) ?
 
Thanks
 
Pascal

By the way, these parameters should not be tweaked without fully  
understanding the implications. This is not some magic "go fast" button.

Subject: [Zope] Updating BLOB fields in Interbase database
Message-ID: <dcd0n1$ida$1@sea.gmane.org>

I'm not sure if this is the right place for this, if not, my apologies.

I've got a Clients table in an interbase db with various fields, one of
which is a BLOB field (subtype text), used to maintain some notes.

When inserting a Client into the table, this field populates fine.

However, when attempting to update the client, for some reason, it won't. It
just will not allow me to do an update with the notes field in the
statement. I've googled around, and found lots of bits helping with Delphi,
and lots of statements that BLOB fields in Interbase are tricky to update,
but nothing that helps.

Has anyone out there found a way around this?

I'm using currently using gvib as my database adaptor, as kinterbase does
not seem to want to install at all (seemingly problems with ldap ..).

My Zope instance is installed from a Plone installer.
      Zope Version  (Zope 2.6.1 (binary release, python 2.1, win32-x86),
python 2.1.3, win32)
      Python Version  2.1.3 (#35, Apr 8 2002, 17:47:50) [MSC 32 bit (Intel)]
      System Platform  win32


Thanks in advance
Ashley

Message-ID: <20050729114815.89576.qmail@web25804.mail.ukl.yahoo.com>

Using relative paths doesn't seem to work as i
thought.
For example :
I have a Plone site "Plone"
Under that i have a folder object named "Sales"
In Sales i have a Page Template object named
"SalesPage".
I also put an "index_html" file object inside Sales
Folder.
I thought that the href inside index_html linking to
SalesPage to the same folder would be "./SalesPage".
This works fine from inside the ZMI witch gives me
"http://localhost:8080/Plone/Sales/SalesPage".
The problem is when i try to see the page from outside
ZMI witch gives me "http://localhost/SalesPage".

So i had to change the href to "./Sales/SalesPage"
This one gives
"http://localhost:8080/Plone/Sales/Sales/SalesPage"
inside ZMI and
"http://localhost/Plone/Sales/SalesPage" outside the
ZMI.
The funny thing is that they both work and give the
page i wantto see but i thing
"http://localhost:8080/Plone/Sales/Sales/SalesPage"
sould not work since i do not have any
"/Plone/Sales/Sales" Folder object.

I use Zope 2.7.0 on Windows XP Pro and i have
installed Hotfix_20040714
Could anyone help me on this?
How sould i reffer to current folder instead of "."
from an html inside this folder?


Thanks in advance.

Hi Tim,
You are right, I had things confused quite a bit there. Well, I guess I learned
quite a bit about sockets in the last few days :)

By design, to keep the sockets around, and being able to inspect them afterwards.

yes, I was aware of that ;) (I thought it was an error for another _server_ 
socket to start listening on the same port, even when the first server socket is 
closed, as long as there were client sockets connected via the port. But I agree 
it is not.)

The problem with a failing connect, and as consequence a hanging accept:
I have tested with your socktest111(), and experience the same thing with that 
as with my own one-go scripts:
The socktest111() test hangs on accept() after a few (1, 2, 3...) cycles, 
because the w.connect fails (10061, 'Connection refused').

Well, enough with that - I can only recreate that problem on my own machine.

I have run the same test on another win xp home, and win 2K without that problem.

(I have tested with your newest script also, see the next mail).

Hello Andreas and thank for your answer. I've posted this question to 
at-users
list too but still no answer. In fact this problem is not related only to 
AT. Let me 
give you an example:

var alternative = 'bar' or 'baz'
var foo_baz = 'content based on baz'
var foo_bar = 'content based on bar'

These can be defined either in ZPT, DTML or Python Script. The problem is 
the same.
The question is how can I obtain the value of foo_$alternative.

An example written in PHP:

$alternative = "bar";
$foo_bar = "content based on bar";
echo ${"foo_".$alternative} 

This will produce "content based on bar".

Thanks for your time,
Cristi

same in a Python-Skript:
------------------------------------------------------------------
foo = {"bar": "content based on bar",
       "baz": "content based on baz",
      }
alternative = "bar"

print foo[alternative]
------------------------------------------------------------------

or, if foo_bar and foo_baz are attributes in your current context:

------------------------------------------------------------------
alternative = "bar"
print getattr(context, "foo_%s"%alternative)

I don't know if this is what you are looking for, but can use a form of indirection that is available thru dtml:

<dtml-call "REQUEST.set('a1', 'aaa')">
<dtml-call "REQUEST.set('b1', 'a1')">

<dtml-var b1>
<br>
<dtml-var "_[b1]">

will print:

a1 
aaa 

This will allow you to load variable b1 within a 'pointer' to a variable containing the data you want.

  Hello Andreas and thank for your answer. I've posted this question to at-users
  list too but still no answer. In fact this problem is not related only to AT. Let me 
  give you an example:

  var alternative = 'bar' or 'baz'
  var foo_baz = 'content based on baz'
  var foo_bar = 'content based on bar'

  These can be defined either in ZPT, DTML or Python Script. The problem is the same.
  The question is how can I obtain the value of foo_$alternative.

  An example written in PHP:

  $alternative  = "bar";
  $foo_bar = "content based on bar";
  echo ${"foo_".$alternative} 

  This will produce "content based on bar".

  Thanks for your time,
  Cristi

    Please ask AT related questions on the at-users list. In general you should 
    not access attributes in AT directly but only through the accessor methods.
    There is something like getField(fieldname) in the AT which might help you
    (look also at the AT docs).

Thank you all very much for your answers. 
The second solution that Jo provided worked exactly as I wanted:

.. tal:content="python: getattr(obj, 'Title_%s'%lang)"..

A good day to you all,
Cristi

The attached hasn't failed on my box (Win XP Pro SP2, Python 2.3.5)
for about two hours, running it in 3 processes.  Was using 2 processes
before; discovered it was much easier to provoke problems using 3; but
the # of ephemeral ports in use increases too, typically hovering
between 7-8 thousand after reaching steady state.

I'll let it run the rest of today, and start changing ZODB code if it
still looks good.  I hope someone(s) else will then volunteer to port
the Windows changes to all the copies of Medusa code in the various
active Zope trunks and branches.

This suffers from what I still believe to be bugs in the Windows
socket implementation, but there is only one symptom I see with this,
and the code uses try/except to implement what appears to be a
reliable workaround.

import socket, errno
import time, random

class BindError(Exception):
    pass

def socktest29():
    w = socket.socket()

    # Disable buffering -- pulling the trigger sends 1 byte,
    # and we want that sent immediately, to wake up asyncore's
    # select() ASAP.
    w.setsockopt(socket.IPPROTO_TCP, socket.TCP_NODELAY, 1)

    count = 0
    while 1:
        count += 1
        # Bind to a local port; for efficiency, let the OS pick
        # a free port for us.
        # Unfortunately, stress tests showed that we may not
        # be able to connect to that port ("Address already in
        # use") despite that the OS picked it.  This appears
        # to be a race bug in the Windows socket implementation.
        # So we loop until a connect() succeeds (almost always
        # on the first try).
        a = socket.socket()
        a.bind(("127.0.0.1", 0))
        print 'b',
        connect_address = a.getsockname()  # assigned (host, port) pair
        a.listen(1)
        try:
            w.connect(connect_address)
            print 'c',
            break
        except socket.error, detail:
            if detail[0] != errno.WSAEADDRINUSE:
                # "Address already in use" is the only error
                # I've seen on two WinXP Pro SP2 boxes, under
                # Pythons 2.3.5 and 2.4.1.

            # Close `a` and try again.  Note:  I originally put a short
            # sleep() here, but it didn't appear to help or hurt.
            print
            print detail, a.getsockname()
            a.close()
    
    r, addr = a.accept()  # r becomes asyncore's (self.)socket
    print 'a',
    a.close()
    print 'c',

    return (r, w)

sofar = []
try:
   while 1:
       print '.',

If I would want to increase the script vocabulary, I would
add "request".

"root" is very rarely used...

When Zope internally modifies the URL (to something different
than what is know by the browser), it must tell the browser
about this -- using the so called HTML "base" tag.

Zope can set the "base" tag automatically provided
the generated page contains a "head" tag without a "base" tag.

If your page meats this requirements and you do not see
the generated "base" tag (tell you browser to show you the
HTML source and look out for the "base" tag) or the
"base" tag has the wrong value (it should end in "sales/"),
then you hit a bug (such bugs have been occationally introduced
in the past).

I can tell you that this is not the case.

A colleague of mine currently hunts a difficult bug in DCO2
which causes wrong query results with a probability of about
0.0025 (non empty "long" fields are non-deterministically
reported as "None").


He also tried cx_Oracle. It is more reliable but by a factor
of 4 slower than DC02.

+1 (if this ever becomes a vote)

The PageTemplates and Python Scripts should meet somewhere and become
more identical in how their zope magic works. Just!! for the sake of
not confusing beginners.

I agree that SO_EXCLUSIVEADDRUSE is not interesting - I was too focused on what
I thougth was an error (See the previous posts ).

After your first post I changed select_trigger.py of medusa in my zope
installation to work like the ZODB 3.4 code (like the ZODB svn trunk). The
problem I had with blocks during accept() is not appearing, and my zopes are
running fine.



Tests:
A)
socktest111 on win2k:
It runs fine for more than 3 hours, but a few (1 out of 100) exceptions on 
bind() (a printed x) appears.

B)
socktest15 on my winxp home sp2
With SO_EXCLUSIVEADDRUSE:

Has been running for 4 hours without problems.
Needs ports down to around 19800.

Without SO_EXCLUSIVEADDRUSE:
it fails after very
few cycles, (just like socktest111) like this:
. . . .
Traceback (most recent call last):
   File "peters2.py", line 72, in ?
     stuff = socktest15()
   File "peters2.py", line 33, in socktest15
     w.connect((host, port))
   File "<string>", line 1, in connect
socket.error: (10061, 'Connection refused')

(The old problem. I can't reproduce it on other machines.)

C)
socktest15 on win2k:
With SO_EXCLUSIVEADDRUSE:
Runs fine for more than 3 hours, needs ports down to around 19800
I did not get an "Address already in use" in that amount of time.
Without SO_EXCLUSIVEADDRUSE:
Runs fine for more than 3 hours, needs usually only to go down to 19998

I have not yet been able to get access to the machines for a longer period.
As said above socktest111 and socktest15 (without SO_EXCLUSIVEADDRUSE) fails 
immediately on my own machine, so I have not yet been able to reproduce the 
processes swapping connection (the failing assert).


D)
socktest2 on my winxp home sp2:
Have run it several times.
Fails after a varying amount of time (2-15 minuttes) with an (10048, 'Address
already in use') in connect. (Just like you experienced). Sometimes both
processes fail at the same time, sometimes only one of them.


C) socktest29
Will try to run that now, and let run a while.

You probably want to run with the head of the 1.4 branch:  there has
been at least one 2.8-compatibility fix checked in since CMF 1.4.8 was
released.  It is possible that somebody may release a 1.4.9 version (but
it won't likely be me).

Subject: [Zope] Zope 3 Bug Day Summary
Message-ID: <200507292039.15531.srichter@cosmos.phy.tufts.edu>

Hello everyone!

I just wanted to let everyone know that we had a very successfull Zope 3 Bug 
Day today! I would like to thank Zope Corporation, POV, Nuxeo and the other 
community members for supporting this event by providing the manpower we 
needed!

We were able to fix all outstanding bugs that prohibited us from making the 
first release candidate of Zope 3.1. As a result, I will create the 3.1 
branch today, lift the feature freeze, and make a release later this weekend 
or first thing on Monday.

Here is a list of participants and their contributions:

- Gary Poster (Gary Poster): Fixed 397. Postponed 372. Removed XXX's.

- Benji York (benji_work): Postponed 296, 316. Removed XXX's. Fixed 411.

- Jim Fulton (J1m): Closed 344. Fixed 384.

- Marius Gedminas (mgedmin): Removed duplicate tests. Fixed up forms. Fixed 
  302! Closed 327.

- Albertas Agejevas (alga): Closed 336. Fixed 381.

- Julien Anguenot (anguenot): Fixed 307. (Julien also fixed many bugs in 
recent weeks.)

- Garrett Smith (garrett-smith): BBB code removal. Fixed 414.

- Stephan Richter (srichter): Closed 302, 413, 415, 416, 419, 421.

Additionally I want to thank Dmitry Vasiliev (hdima) who was not able to 
attend today, but was the most active community members in the last weeks to 
fix bugs and ensure the full internationalization of Zope 3.

Thanks again to everyone for participating!

Regards,
Stephan

	Cache Manager?
Message-ID: <90fc544a05072923533afde9c5@mail.gmail.com>

I have read the zope book and zope online help about RAM Cache
Manager. But all of them didn't say anything about the parameter "What
"Maximum age of a cache entry (seconds)" mean.
It looks that this parameter like "Cleanup interval (seconds)", which
zope book explained as "The lifetime of cached results.". But what
this parameter mean? Would somebody give me an explaination?
Thank you.

I have been running 8 simultaneous processes with socktest29() for
12 hours, on my xp box. No problems except for an occasional "Address already in 
use".

I want to second this thanks.  I'm very happy to see 3.1 finally nearing
completon.

P.S. I'd like to remind everyone that there are just 3 months left before
      the feature freeze for 3.2. :)

Subject: [Zope] inspect and page templates in python product
Message-ID: <bc95c280050730091042b4681d@mail.gmail.com>

I'm using the inspect module in my python product to step back when
doing some debugging.
My code looks something like this::

class MyProduct:
  
    def hasRole(self, r):
          for i in range(25):
              try:
                  print inspect.stack()[i][3], 
                  print inspect.stack()[i][2], 
               except IndexError:
                  break

It works wonderfully well except when the caller of hasRole() is a
Page Template defined with the PageTemplateFile function. (it might be
equally bad with a ZODB persistent template I think).

Does anybody know if and how if there is a way to step back and found
out which template called hasRole() [ and maybe even which line] ?

If I do this debugging now, it gives me something like:

(hasRole:326, <expression>:1, __call__:47, evaluate:221,
do_condition:636, interpret:234, do_defineSlot:694, interpret:234,
no_tag:389, do_optTag:394, do_optTag_tal:409, interpret:234,
do_useMacro:671, interpret:234, __call__:190, pt_render:96, _exec:106,
_exec:343, _bindAndExec:343, __call__:306)

It means exactly as it seems to mean.

Maximum age:

No cache entry older than n seconds, where n is the value you supply for
that setting, will be used.

Cleanup interval:

Appx every n seconds, sweep the cache and remove entries that are
expired, as in the above parameter.

You would not want to do this too often (for performance reasons) nor
too little (lest the cache become very large).

I can't find an appropriate list for this, but this one seems the best
fit. I have a need to obtain local roles for my folder-like product
from an sql database. How do I redefine the functions that handle
local roles? I don't know what their names are.

I do not thing that this is "ZSyncer"'s purpose.

to achieve what end?

We are using a high availability cluster to avoid the ZEO single point
of failure.

ZC hat a (commercial) replication tool.

Look at how "ExceptionFormatter" (in package "zExceptions") examines
the stack for "__traceback_info__" and "__traceback_supplement__".
You can in a similar way detect when you are in a PageTemplate
method. PageTemplates have attributes describing the current sourcefile
and line number.

One of my projects has a requirement for providing
99.99% uptime when hosting in their data center.  Our
Zope / Plone solution will be replacing an ASP / SQL
Server solution that has 2x web servers and 2x SQL
Servers (using log shipping).

Tentatively, my hosting recommendation resembles two
web servers, running Apache / FastCGI / Zope, and then
two servers running ZEO / ZODB and ExFile.  My current
thoughts would be to commission SAN space between the
two ZEO servers so that the Data.fs, etc. would be
shared between the two database servers.  SAN space is
expensive, though, so when I saw a posting about
Zsyncer, I was wondering if there might be a solution
for keeping two instances of a ZODB synced up.

We already have two Cisco CSS to handle heart beats
and failover.

Thanks for the responses...

It's really only intended for manual sync of smallish amounts of 
data.  I would not rely on it for automated mirroring of an entire ZODB,
even if you can cook up some appropriate scripting it is unlikely to be
fast enough for that.

If you need "warm" or "hot" failover of your ZEO server, or you have
such intense performance that you need to load-balance among multiple
live ZEO servers, then the only solution I am aware of is Zope Corp's
ZRS product, which is commercial and AFAICT is priced according the
(probably reasonable) assumption that anyone who really needs it has
pretty deep pockets. See zope.com for more info.

For free / open-source solutions, AFAICT it may be possible to
have automated cold failover, but not multiple live ZEO servers
at once. I'm currently investigating the possibility of automated
cold failover using DirectoryStorage's replication tool to keep the
backup system up to date. (See recent thread "Replication and cold
failover" on dirstorage-users mailing list, find archives at
dirstorage.sf.net).  You could probably do something similar
with Filestorage by using repozo to frequently make incremental
backups, and rsync to copy them to your backup server.

The magic attribute is '__ac_local_roles__'.  By default, it is stored
as a dictionary on the object, keyed by user ID.  You can define it as a
callable, however, returning a mapping.

You will need to avoid deriving from AccessControls.Role.RoleManager,
however, or at least suppress / override the local roles tab for your
objects;  otherwise, your users might shadow your callable with a normal
dict (by calling 'manage_addLocalRole', 'manage_setLocalRoles', or
'manage_delLocalRoles').
