At the beginning of the Month there was a 4 post discussion about this topic. I recently had the same problem as Sake. > os.environ['PYTHONPATH'] = SOFTWARE_HOME <---------------- inserted line This line was questioned to be added to zopeservice.py. I tried it and it made my pain go away. I'm using Windows 2003 server for this.

Re: [Zope-dev] ZPT for CSS, anyone?

If you mean prior to rendering the ZPT, the nthat wasn't a usecase you specified ;-) If you mean post-rendering, use a PageTemplateFile and whatever you want inside it.

Pointless exception re-raising in DA.py
by Chris Withers 30 Mar '04

30 Mar '04

Hi All, In Shared/DC/ZRDB/DA.py, Line 399 of Zope 2.6.1 and line 419 in 2.7.0, there's this rather pointless lump of code: try: DB__=dbc() except: raise DatabaseError, ( '%s is not connected to a database' % self.id) ...which only serves to mask the real cause of the problem when trying to obtain a connection. Would anyone have any objections if I changed this to simply: DB__ = dbc() ? (if no responses, I'll assume that means you agree with my proposed change ;-) Chris -- Simplistix - Content Management, Zope & Python Consulting - http://www.simplistix.co.uk

InvalidObjectReference: Attempt to store an object from a foreign database connection
by Christian Heimes 29 Mar '04

29 Mar '04

There is a problem regarding plone, cmf and the quickinstaller tool. I'm getting an InvalidObjectReference error after reinstalling a product with the quickinstaller a second time or several times. It looks like the error happens only after I visited the plone ui at least once but that could be concurrence. Only restarting zope stops the error until the next occurance. Version: Python 2.3.3 (Debian testing) Zope 2.7 (CVS branch) CMF 1.4 (CVS) Plone 2.0 Traceback (innermost last): Module ZPublisher.Publish, line 104, in publish Module Zope.App.startup, line 224, in commit Module ZODB.Transaction, line 233, in commit Module ZODB.Transaction, line 348, in _commit_objects Module ZODB.Connection, line 419, in commit - __traceback_info__: (('Products.CMFCore.ActionInformation', 'ActionInformation'), '\x00\x00\x00\x00\x00\x00\x9e\xe3', '') InvalidObjectReference: Attempt to store an object from a foreign database connection I tried to get the object by starting zope with zopectl debug and using app._p_jar['\x00\x00\x00\x00\x00\x00\x9e\xe3'] but the object wasn't available so it seems to be a new object that is saved the first time. After changing the pickler from cPickle to pickle: Traceback (innermost last): Module ZPublisher.Publish, line 104, in publish Module Zope.App.startup, line 224, in commit Module ZODB.Transaction, line 233, in commit Module ZODB.Transaction, line 348, in _commit_objects Module ZODB.Connection, line 419, in commit - __traceback_info__: (('Products.CMFCore.ActionInformation', 'ActionInformation'), '\x00\x00\x00\x00\x00\x00\xa2G', '') Module pickle, line 231, in dump Module pickle, line 293, in save Module pickle, line 663, in save_dict Module pickle, line 695, in _batch_setitems Module pickle, line 278, in save InvalidObjectReference: Attempt to store an object from a foreign database connection pickle.save():278 is calling self.persistent_id(obj) which is patched to call coptimizations.new_persistent (pickler.persistent_id=new_persistent_id(self, stack)) in ZODB.Connection.commit(). The exception itself is raised by persistent_id_call() because of (jar != Py_None && jar != self->jar) is true. Debugging so deep into the zodb is a bit over my knowledge so I would be glad if someone could dig in, too. :) Christian PS: CC to plone-devel and cmf

Use Z SQL methon in projects
by R33t 29 Mar '04

29 Mar '04

Dear list, I'm quite new to zope and I have to develop a Newsletter system as a project for my university. All works pretty good so far, I'm using ZPT with embedded Z SQL methods to create my page dynamically....the code looks like this: ... <b>Newsletters</b><br> <table cellpadding="5" cellspacing="0" border="1" width="250"> <tr tal:repeat="newsletters here/getNewsletters"> <td align="left"><font size="2"> <input type="checkbox" name="newsletter" tal:attributes="value newsletters/id"> <p tal:replace="newsletters/newsletter_name">NewsletterName</p> </td> </tr> </table> ... I did all the things so far inside the Zope ZMI to see how things work together, but now I'd like to create a "real" project and I already got most of the things working, like calling the page templates from within python. The problem I have now is that I don't know how to manage to export my Z SQL method getNewsletters to my product folder and register it to Zope from within python when my product gets installed, so that the template can call this method like before...I don't want the users of my product to manually create this Z SQL method when they install the newsletter system. Is it possible at all or do I have to start all over again? any help would be appreciated thanks a lot reet

Zope 2.7 memory behaviour
by Arndt Droullier 29 Mar '04

29 Mar '04

Hello, I´m trying to find a memory leak in a zope appliction and started to test how zope memory consume behaves basically under load. The current result is: Zope constantly consumes more memory. The testcase is: 12 http clients request constantly request the same page template (it does not contain any tal statements and only 10 lines of HTML) in a simple folder. The increase is about 50 - 100 kb / minute. I´m using Windows 2000 as server platform. The database cache and debug information on the control panel seem allright. Now I wonder if there´s basically a problem with Zope 2.7? Has anyone made the same experience? Or an explanation why this happens? Thanks, Arndt.

university research survey on Zope community organization
by Nicolas Jullien 29 Mar '04

29 Mar '04

Hello, We (some French researchers in economics and sociology from ENST Bretagne graduate school and CNRS), are working on free-open source software production and diffusion. To do so we have chosen to focus on some projects, an Zope is one of them. We have already met some Zope contributors, such as Paul Everitt, and today we survey (http://www-eco.enst-bretagne.fr/Etudes_projets/cgi/questionnaire_Zope.cgi) Zope developers. Your answer is very, very important for us, and for statistical reason we ask to everybody on the list to answer. The survey is online and takes 5 to 10 min to fill in (http://www-eco.enst-bretagne.fr/Etudes_projets/cgi/questionnaire_Zope.cgi) Your answers will remain anonymous and will not be disclosed or used for other purpose than statistic work within that project. Feedback on the survey results will be published as soon as they will be produced. Thank you very much by advance for your help ! Nicolas Jullien, Didier Demazière, François Horn PS: in a second time, we will make a survey on the 'whole' Zope community, on Zope-announce. Of course, you won't need to fill in tis questionnary. -- Coordinateur des programmes de recherche Marsouin. (PhD) Research projects coordinator for Marsouin.

I have made some small modifications to test.py to allow testing in INSTANCE_HOMEs.
