[Zope] Version seems to LockOut

Maslak, Michael mmaslak at anteon.com
Tue Dec 6 10:59:45 EST 2005


Attempting to use the Version to stop from stepping on each others' code results in a LockOut error that seems to propagate to any object the code in the version touches.  For example, if the versioned object uses

<dtml-var standard_html_header>

then standard_html_header gets locked and the site becomes inaccessible.


What am I doing wrong?

I once started down that path with FTP.  I use HomeSite, as well, to 
save via FTP.  I investigated a Linux package called Delegate, that 
would provide a rev-proxy for FTP over SSL, in which normal FTP clients 
with SSL could transfer files.  www.delegate.org

I didn't continue, priorities and all.

Maybe a WebDAV client over SSL would be easier, depends on your needs.

Zope 2.8.0
Python 2.3.5
RHEL 3

I installed TextIndexNG 3.1.1 and associated extension_modules without
a problem.  Trying to add a TextIndexNG index to my catalog returns:

Error Type: ComponentLookupError
Error Value: 'Utilities'

I'm pretty sure I followed all instructions and I've installed and
used previous versions of TextIndexNG without a problem on other
instances of Zope 2.8.x.

Can anyone help figure out what's going wrong?  Traceback follows...

I am still missing a detailed description from your side how to reproduce 
this behaviour on nacked Plone or Zope installation.

Sorry, I created a ZCatalog and when choosing TextIndexNG3 from the
"Add" dropdown in my ZCatalog's Indexes tab, it immediately gives me
this error.

Works like a charm..Somehow your Zope installation must be borked.
Try with again with a fresh 2.8 installation.

Is there so,ething missing here?

http://www.cps-project.org/sections/about/screenshots/cps_sites_screenshots/

Is there an example of it in use anywhere?


Can't tell if it works with just Zope or whether it needs Plone.

How do I access the subfolder of a parent folder? I am using the following

<dtml-call "REQUEST.set('parentFolder', PARENTS[2].id + 'Test')">
<dtml-call "REQUEST.get('parentFolder').initialize_vars()">

I get the following error:

Error Type: AttributeError

I understand that a DTML method cannot be called on a string, but how do I 
obtain the object that represents the subfolder 'Test'? Any help would be 
appreciated. Thanks.

Hello,

I found the source of my problem uploading a large file to ZODB over 
DAV and an a workaround that shouldn't have worked but worked. For 
those who are interested:

For completeness:

>  >I would like to put a 120MB file into ZODB and it is constantly failing.
>
>But you should have learned that you cannot simply say "is failing"
>but must describe precisely (error information, traceback) *how*
>it is failing...

Correct Dieter, I was vague but it indeed would progress and then 
fail. Goliath, a mac web dav client, would report "Unknown connection 
error" and the Finder would report "... cannot be completed... one or 
more required items not found (error code -43) I apologize that I am 
not familiar with Zope's traceback.

Thank you to Tino for providing a script to copy files into ZODB. 
This solves a few other issues.

So. I knew to watch my /tmp directory and it was not being used. It 
turns out that Python (presumably, not Zope) was using /var/tmp (over 
RAM, given that large-file-threshold in zope.conf was lower than 
120MB).

I linked /var/tmp to /tmp and oddly it started using /usr/??? but at 
least it worked because there was more than 120MB available there. I 
am not quite sure where it ended up putting it. (seemingly not /var 
in the zope instance)

The solution appears to be that python can use the TMPDIR variable to 
specify where tmp should default to (reportedly it will try various 
locations) but, I am not clear how I can add this to Zope's rc script 
to declare it. I tried it as simply setting the environment variable 
"set TMPDIR=/tmp" but that gave warnings about the startup logic.

1. Should TMPDIR work?
2. Where should I declare it when using rc scripts?
3. Any chance zope.conf can use it?

I have a zope instance listening on localhost. I use apache and fastcgi to
reach zope. Now I would like to provide webdav. Since my apache is already
doing ssl, I wanted webdav connections to also go through apache.

when I use cadaver and connect to my zope zope through apache, all works
well even though I have specified in my zope.conf file that  webdav listen
on localhost:8088 (it seems that cadaver is smart enough working through the
fastcgi interface to just work).

When attempting to using dreamweaver mx or windows webfolders to connect to
zope I get an error.

So I attempted to use an apache proxy pass directive to campture all urls at
myzopeserver.edu:8088/webdav back to localhost:8088. This had no effect.
cadaver was still able to work. Dreamweaver (using webdav site setup) and
windows webfolders still failed.

What deep magic do I need to make dav work through apache? ( would prefer to
have all things go through fastcgi but I understand the trend is to use
proxy-pass )

Content-Type: text/plain; charset=US-ASCII; delsp=yes; format=flowed

I'm wondering if someone can point me in the direction of some  
documentation that will tell me the best way to translate a web page  
into multiple languages using Zope Page Templates.  In previous sites  
we've done in DTML we used a 'phrases' table in our MySQL database  
that contained phrases in each language the site required.   We then  
used sql methods and a dtml-let statement to create a list of the  
phrases used on a certain page.  I'm considering using the same basic  
idea for a page template site, but am wondering if there is a better  
way of doing translations.  I've read about using .po files.  Is  
there an easy way to hook these up to Zope? Any help would be greatly  
appreciated.

Thanks.

Thanks for the many replies. I apologise for the original message which was 
obviously very unclear - I will try to correct that.

Basically I want to match a telephone number to a rate table. Assume the 
following rate table:
Telephone code    Rate
649                1
6421                2
6422                2.5
64                 1.5

The following table sets out the appropriate rate to return for a given 
telephone number
Dialled number    Returned rate
649123                     1
643123                    1.5
6421111                    2
64221                      2.5

Things to note:
If there is no match the right-most digit is removed until there is a match 
e.g. 643123 matches to 64
The length of the "dialled number" is not consistent e.g. 649123 vs 64221
The length of the "telephone code" is not consistent e.g. 64 vs 6422

I want to do this frequently and at low cost i.e. ideally in memory. Perhaps 
the best way is to write a procedure in MySQL however I am interested in any 
python-based alternatives.

Regards

Cameron

Yes, that's exactly what I was looking for.  I'm already using Apache
as a proxy for Zserver, so it didn't take much to get SSL working as
well.

I just got this working myself, although I am using apache as a proxy,
not fastcgi.  If you already have ssl working with apache and can
access zope through apache without ssl, it shouldn't be difficult.

The main thing is to add a virtual host in your apache config for SSL
and modify the rewrite line to use https:.  I found the following
document helpful:

http://www.zope.org/Members/tmckibben/HowTo.2004-04-13.0659

It uses FastCGI, so it should more closely match your setup than mine

Your problem is more an algorithmic problem than q question of the data 
representation. Store the mapping as some BTree (possibly IIBTree using 
normalized integers for the values). Then you have to iterate over all 
prefixes of the dialed number starting with the longest prefix to the 
smallest prefix. Then perform a lookup of the prefix in your BTree...
this is should not take more than five lines of code and requires a maximum
of #(length_of_dialed_number) comparisons. If you want it more complicated 
construct a tree and you'll have a logarithmic number of comparisons. I 
doubt that it is worth the effort since the first solution should be fast 
enough unless your dialed number is hundreds of digits long :-)

*hint* use postgres instead where you can write stored functions in
python too :-)
(With some little modifications on the zope database adaptor you 
could even return a dictionary or btree object as result
of your query then :-)

I believe this patch is required if using recent WinXP, due to Microsoft
webdav breakages:

http://teyc.editthispage.com/2005/06/02

It fixed webdav for web folder for me. Add the extra line into the OPTIONS
method of the file mentioned, where other headers are being set.

Yes, there are two alternatives:

PlacelessTranslationService and Localizer both of them allow you to use
po files and negociate the language according to the browser settings or
cookie based (Localizer allows you also a path based negociation ie:
/en for english, /de for german). If you only need to translate label
messages and small paragraphs, then PlacelessTranslationService will be
the way. Localizer can also do the same as its competitor; additionaly
you can also define localized contents (ie: you can have two versions of
a page and they will be selected according to the browser language).

Some days ago, I also read something about integrating the Zope 3.x
translation technolgy into zope 2 using five; it seems interesting as
well:

It works with plain Zope. There are also integration for CPS, and
since the Plone calendaring sprint last weekend, a project to make
Plone integration as well.
For plain Zope, you need to implement some sort of
internationalisation and integrate it with your sites menu system.

(Although I'm currently working on using the Five internationalisation
that comes with Five 1.1 and Zope 2.9).

zope.conf has a directive "environment" for exactly that purpose.

Why do you care about this? AGAIK, this is only to do with those weird

using a normal tcp socket as you should be ;-)

We need more of the traceback, there is no repeating part here so it's 
impossible to see what's causing the infinite recursion...

I know nothing abotu fastcgi, but I doubt you're reachign the source 
port, so if you open a ZPT, for example, you will get the rendered 
version, and if you edit and save it, you will loose all your tal markup.

You could look at the "third product directory" option that used to be 
enabled by setting the PRODUCTS_PATH environment variable, should be an 
option in zope.conf somewhere now...

- yes you can have as many plone instances as you like in one zope instance

- they all run off the same software, so they will be the same version 
of Plohn, etc...

- you can get them in different places on disk my using mounted 
storages, you'll have to have a google and fiddle. This is part of the 
standard zope software, read zope.conf ;-)

- mounted storages are still ZODB-based, there's no such thing as "file 
system storage" ;-)

I'd probably put in the bin/runzope in your Zope instance.

no, unless I'm misunderstanding you...

According to the docs it should be possible to specify an alternate socket 
name. I am unable to use the name 'zdsock' so would like to configure Zope 
to use a user specific socket name. Either it is possible or it isn't.

So far no one has told me how I can use what are supposed to be existing 
features. I've even found a sample.conf which contains this

<runner>
  # Harmless example
  program       sleep 100
  # Repeat the defaults
  backoff-limit 10
  daemon	True
  forever	True
  socket-name	zdsock
  exit-codes	0,2
  # user has no default
  umask		022
  directory	.
  default-to-interactive True
  hang-around   False
</runner>


but no one seems to know how/where this is can be used.

What is the point in having features if no one knows how to use them?

In Zope 2.7.8 I get a segmentation fault when I try to do the above; I 
also have the following code that manages this for any class (to avoid 
having to do that for every single class):

def _ZopifyClass(a_class):
     a_class.security = ClassSecurityInfo()
     a_class.security.declareObjectPublic() # Segmentation fault
     security.setDefaultAccess('allow')
     InitializeClass(a_class)

I cannot swithc to Zope 2.8 because my code runs in PLone 2.05 and it 
does not work with Zope 2.8.

The segmentation fault occurs in the declareObjectPublic() statement.

Is there a fix for the Zope 2.7 to this problem?

Thanks.

is it a typo, or did you mean:

a_class.security.setDefaultAccess('allow')

?
