ZClass and ZCatalog
by Marco Nova 05 Jul '01

05 Jul '01

Hello Guys, I've a problem with a ZClass (JCEvent) I've created and ZCatalog. Base classes for JCEvent are: ZObject, JCObject, CatalogAwareBase. JCObject is another ZClass whose base class is ZObject. Instances of JCEvent are added to a ZCatalog but they are not automatically indexed by the catalog. The catalog is named 'events'. How can I automaticallly index them ? Thanks, - mn

Method invocation after Zope restart
by Paulo M. Goncalves 05 Jul '01

05 Jul '01

Hi everybody, Just one question (maybe a newbie question): After a Zope restart I want to invoke a method from an object instance. Is there a such mechanism builtin in the Zope startup? Or in a more wide perspective, how could an object instance be notified of a Zope restart? Thanks, Paulo ----------------------------------------------------------------------- Paulo Marques Goncalves CDFtel, Lda Ph.

I am trying to use a Zope LDAP Connector to interface with an OpenLDAP server 2.0.7. I compiled the Python LDAP API 1.10 alpha3. Did someone know if there is some problem using this library? I use Zope 2.3.3 on Linux Suse 7.1 Thanks in advance -- Alessandro COTA CSP s.c. a r.l. - INLAB Laboratorio&Tecnologie - PA ______________________________________________ Via Livorno, 60 - 10144 Torino [IT] Alessandro.Cota(a)csp.it tel. +39 011 316 5107 ______________________________________________

I read from an HOW-TO that the problem may reside (beside the name of the catalog) that the first base class id JCObject and not CatalogAwareBase. Is it true ? - mn P.S.

Rename the catalog from 'events' to 'Catalog' and CatalogAwareBase should start working.

Proxy not Propagating - could be FSDTMLMethod
by alan runyan 04 Jul '01

04 Jul '01

this is in the context of CMF, but its a ZOPE Security issue. I have a Script (Python), createJobPosting which is: from DateTime import DateTime path = ('', 'virtual_hosts', 'thecommode', 'Members', 'PUBLIC') PUBLIC = context.restrictedTraverse(path) id = str(DateTime().millis()) PUBLIC.invokeFactory(type_name='Job Posting', id=id) obj = getattr(PUBLIC,id) view = getattr(obj,'job_edit_form') return obj.getEditView() that is Proxied as Manager/Member/Reviewer. it creates a object just fine (in Members/PUBLIC) so then the script then calls obj.getEditView() which is: security.declarePublic('getEditView') def getEditView(self): skins = getToolByName(self, 'portal_skins') if hasattr(skins, 'job_edit_form'): self.editView = getattr(skins, 'job_edit_form') return self.editView(self, self.REQUEST) # i assume this gets a new security context? when its being 'published', how can i proxy this as Manager/Member/Reviewer? I need to render the job_edit_form (filesystem DTML Method) in the same Security Proxy context (as Manager/Member/Reviewer), but upon its publishing it encounters as _.hasattr(this(), 'myAttribute') and says I dont have access to this().

I am going about this the correct way, I believe. ? I also tried to 'customize' the FSDTMLMethod and proxy it as Manager/Reviewer/Member and it still gives me the same error ;'( thanks, ~runyaga

Data.fs & ZEO
by Priya Ramkumar 04 Jul '01

04 Jul '01

Hi I have installed Zope version 2.3.3 & ZEO1.0. I would like to copy the Data.fs from my previous zope installation which is 2.2.4 to the new one. I copied the Data.fs, Data.fs.lock, Data.fs.tmp & Data.fs.old from the old Zope to the "var" directory in the "Instance_home" directory. I start Zope from the "Instance_home" by invoking "zctl.py". After I copied the Data.fs files to the new Zope, I get the following error. File /export/usr/local/Zope3/Zope_software_home/lib/python/ZEO/ClientCache.py, l ine 325, in update File /export/usr/local/Zope3/Zope_software_home/lib/python/ZEO/ClientCache.py, l ine 401, in _store TypeError: __add__ nor __radd__ defined for these operands ------ 2001-07-04T04:01:45 INFO(0) ZEO Server Close 136753056 ------ 2001-07-04T04:01:45 PROBLEM(100) zdaemon zdaemon: Wed Jul 4 06:01:45 2001: The ki d, 75464, died on me. Can anyone please tell me what could be the problem? I am using python version1.5.2. Thanks for any help. Priya

experiments & bugs with data.fs >2GB
by marc lindahl 03 Jul '01

03 Jul '01

I've recently been testing a new setup with XFS (http://oss.sgi.com/projects/xfs/1.0_release.html) and decided to try to bloat data.fs before using this system for production. The computer is set up with zope 2.3.3 installed from source (the old fashioned way, with everything in one directory), with a separate 18GB disk as /usr/local/zope. I uploaded a couple of files -- seawolf disk one ISO image (about 650MB) and SGI's XFS install ISO (about 300MB). Both from another computer via ZMI via a 10 baseT network. (interestingly both loaded up OK, but the seawolf image gave a client side 'page failed to load' error, while the other worked fine. So I suppose 600MB is the hairy edge of filesize you can upload via ZMI) Then proceeded to copy the two files and paste. First time worked fine, pushing data.fs to about 1.9GB. Second time, I copied all 4, which should push data.fs to about 4GB. It seemed to reach about 2.29GB (perhaps copying the first XFS ISO image), then gave this error: -------------------------- Zope Error Zope has encountered an error while publishing this resource.
