ZOPE and ZEO
by Sudesh soni 31 Jul '07

31 Jul '07

BlankIf two diiferent Zope clients are sharing a ZEO storage, then how to adjust siteroot to serve the request coming to individual Zope clients. I am asking because when two Zope servers are up with different URI/subdomain and when I open the ZMI of other Zope client, its siteroot is still pointing to the first Zope client URI. Should I empty the Siteroot value ? Or suggest? I have used mirroring on primary zope client to redirect the request to primary URI to secondary Zope URI . Regards SuSon

from sparc to i386
by Yuri 31 Jul '07

31 Jul '07

Hi all! I've an old zope server running 2.6 on an old sparc. We are going to replace it, so I need to move the Zope thing. The problem is that that Zope server is compiled in sparc and I've made some modification to the source code, so I can't just move it on another machine (including the python 2.1 tree) as is. Which are the best options? Recreate the Zope 2.6 installation, python 2.1 installation and replace the Data.fs? TIA :)

IndexError

31 Jul '07

Hi, I am having IndexError in some of my folders when i tried to view the content of Zcatalog created in these folders, but to my surprise this is not happening in other folders with similar Zcatalog. I am also not experiencing the same problem with objects of the old Zcatalog that I have catalog before this error. In an attempt to correct this error, i had duplicated the old Zcatalog and renamed it. But once i catalog the objects and try to view it, it will show the IndexError again. Traceback (innermost last): a.. Module ZPublisher.Publish, line 119, in publish b.. Module ZPublisher.mapply, line 88, in mapply c.. Module ZPublisher.Publish, line 42, in call_object d..

Increment In PT?
by tonylabarbara＠aol.com 30 Jul '07

30 Jul '07

Hi; I´m trying to increment a variable in a page template. Here´s the general idea in my code: <div metal:define-macro="main" tal:define="x python:0"> <tal:block tal:define="x python:x + 1"> <td> <input type="hidden" tal:attributes="value item/name; name python:'item_name_' + `x`"> Now, all of that works...once. That is, it increments from 0 to 1, but not from 1 to 2! Each time I pass through the td element, I need it to increment. I tried putting the tal definition in the td, but then it didn´t even increment once! What do? TIA, Tony ________________________________________________________________________ AOL now offers free email to everyone. Find out more about what's free from AOL at AOL.com.

Hi Jonathan, I'm sure that what you said is right but 1) I tried to change my script performing a manage_add that should be performed after timeout. Nothing happened. 2) However the only way I see is: a- keep the session id in the request b- if request.savedsessionid<>session.id then alert "session timed out" thank you for your help ---------- Initial Header ----------- >From : "Jonathan" dev101(a)magma.ca To : jbusato(a)libero.it,"zope" zope(a)zope.org Cc : Date : Sat, 28 Jul 2007 08:17:08 -0400 Subject : Re: [Zope] TOC ondelete event > > ----- Original Message ----- > From: <jbusato(a)libero.it> > To: "zope" <zope(a)zope.org> > Sent: Saturday, July 28, 2007 7:15 AM > Subject: [Zope] TOC ondelete event > > > I'm setting up a Session data Manager with a Transient Object Container > > that call a python script session_delete? > >(sdo,toc). > > > > I want to show a message like ("your session was terminated due > > inactivity") so I tried to write this > > > > #PYTHON SCRIPT (NOT EXTERNAL) session_delete(sdo,toc) > > request = container.REQUEST > > RESPONSE = request.RESPONSE > > RESPONSE.redirect(container.mywarningpage.absolute_url()) > > > > Launched manually it gives me no errors but when the session is terminated > > only "onadd" script make effects. > > > > Are there not permitted operations in this case? > > Could anyone explain me where I mistake or another way to do tha same > > thing?

Conflict errors
by Sudesh soni 30 Jul '07

BlankHi, I am frequently recieving conflict errors like below in Zope logs. We have ZEO implemented with 2 Zope servers accessing the storage and even then its not minimizing . Could anyone suggest whats happening here that cause this error. Is my Apache configuration also needs to be looked for to fix this OR its an inherent ZOPE bug ------------------------------------------------------------------------------------------------------------ Exception Type ConflictError Exception Value database conflict error (oid 0x09, class Products.Transience.Transience.Increaser, serial this txn started with 0x036f460d13550f66 2007-07-27 17:17:04.531000, serial currently committed 0x036f460e67cca9dd 2007-07-27 17:18:24.328000) --------------------------------------------------------------------------------------------------------------- SuSon

Inconsistency in the SVN repository with download package (Zope 2.9.8)?
by donat.hutter＠bluemail.ch 29 Jul '07

29 Jul '07

This refers to ZOPE 2.9.8 When I did an analysis with "fsrefs.py" of a Plone database (Data. fs) I got a lot of "missing" messages. I crosschecked the file "fsrefs.py" of the downloaded ZOPE package with the SVN repository. I recognized, that the file from ZODB/tags/3. 6.3/src/scripts commented as "tagged for Zope 2.9.8" (this works perfect, see change history below) is not identical with the on in the download package. I didn't check any other files. > Zope: ZODB/tags/3.6.3/src/scripts/fsrefs.py > _____ > Revision 77338 - (Modified Tue Jul 3 13:32:55 2007 UTC (3 weeks ago) by andreasjung > File length: 5885 byte(s) > 3.6.3 (tagged for Zope 2.9.8) > _____ > Filename: ZODB/branches/3.6/src/scripts/fsrefs.py > Revision 69277 - (Modified Thu Jul 27 21:55:20 2006 UTC (11 months, 3 weeks ago) by tseaver > File length: 5885 byte(s) > fsrefs.py was reporting spurious 'missing' classes. > > It seems that for the download package the file from "ZODB/trunk/src/ZODB/scripts" is taken ??? regards, Donat

TOC ondelete event
by jbusato＠libero.it 28 Jul '07

28 Jul '07

Hi, I'm setting up a Session data Manager with a Transient Object Container that call a python script session_delete(sdo,toc). I want to show a message like ("your session was terminated due inactivity") so I tried to write this #PYTHON SCRIPT (NOT EXTERNAL) session_delete(sdo,toc) request = container.REQUEST RESPONSE = request.RESPONSE RESPONSE.redirect(container.mywarningpage.absolute_url()) Launched manually it gives me no errors but when the session is terminated only "onadd" script make effects. Are there not permitted operations in this case? Could anyone explain me where I mistake or another way to do tha same thing? (AFAIK sdo parameter is the old session so I can't store any info in it) Thank you so much Jary Busato ------------------------------------------------------ Scegli infostrada: ADSL gratis per tutta lestate e telefoni senza canone Telecom http://click.libero.it/infostrada

acquisition failure puuzzle or maybe something else
by Dennis Allison 27 Jul '07

Zope 2.9.X Python 2.4 Centos 4.4 Linux Firefox 2.0.0.5 (Linux and Win XP) I have a dtml method is a folder C and a folder setup / A B C scripts In the dtml method, there is a call to a script passing in a composed string made up of variables passed in through request inside of a dtml-let, <dtml-let someval="scripts.cleanfilename(cgivar1+'_'+cgivar2)" > --- methods that use someval --- </dtml-let> a pattern we have used in many places without a problem. In this particular case, Zope throws an error Traceback (most recent call last): File "/usr/local/src/zope/Zope2.9/lib/python/ZPublisher/Publish.py", line 115, in publish request, bind=1) File "/usr/local/src/zope/Zope2.9/lib/python/ZPublisher/mapply.py", line 88, in mapply if debug is not None: return debug(object,args,context) File "/usr/local/src/zope/Zope2.9/lib/python/ZPublisher/Publish.py", line 41, in call_object result=apply(object,args) # Type s<cr> to step into published object.

Now, the failing element is part of a method that fundamentally has a if-elif structure and the actual code fragment is embedded in a pair of nested <dtml-in> blocks which have internal <try>-<except>-<else> blocks, but that is all control structure and should not impact name/attribute resolution, or so I believe. A trace through the executing method shows the control flow is functioning as expected. Security settings appear to be correct--and the correct execution of simple test methods (see below) tend to support that conclusion. Moving the script into the same folder as the method (that is, moving it from the folder scripts to the folder C in the layout above) is a workaround, but it breaks our coding conventions. i Simple test methods in folder C <dtml-var standard_html_header> <dtml-let sss="scripts.cleanfilename('able baker charlie ')"> <dtml-var sss> </dtml-let> <dtml-var standard_html_footer> work fine and do not throw the attribute error. I suspect that this is a problem caused by some trivial error, but we've been unable to find it. Any help/suggestions as to how to resolve this puzzle would be appreciated.

Extracting all files from Zope DB
by Nokin Jérôme 26 Jul '07

26 Jul '07

Hello, In order to migrate from Zope to "..." (I don't know yet), we are trying to extract all the information located inside the Zope database. I've found the FTP interface to the Zope database, I can browse inside the subfolder but, I can see any files !? If I post a new file via the web page, a folder is created (I see it via FTP) but the folder is empty ?! Could you please tell me if there is a way to do that ? Could you please give me some hints ? Thank you very much ! Jerome Nokin
