Question on traceback/readconflicterror
by Marco Bizzarri 08 Mar '05

08 Mar '05

Hi all. I know ReadConflictError should be normal inside Zope Transactions. However, I've 4 or 5 of this errors each day: 2005-03-08T10:01:51 ERROR(200) KeywordIndex unindex_object could not remove documentId -895169661 from index workitems_from. This should not happen. Traceback (most recent call last): File "/home/zope/zope-2.7.4/lib/python/Products/PluginIndexes/common/UnIndex.py", line 185, in removeForwardIndexEntry indexRow.remove(documentId) File "/home/zope/zope-2.7.4/lib/python/ZODB/Connection.py", line 599, in setstate invalid = self._is_invalidated(obj) File "/home/zope/zope-2.7.4/lib/python/ZODB/Connection.py", line 628, in _is_invalidated raise ReadConflictError(object=obj) ReadConflictError: database read conflict error (oid 0x317235, class BTrees.IIBTree.IISet) Is there something I should worry? Regards Marco

LocalFS 1.3 and PDF Mime Types
by Edward Pollard 08 Mar '05

08 Mar '05

We're having problems with PDF files server via Zope and LocalFS 1.3 (andreas). Mime types for the PDFs come back with surprising irregularity. Given a directory of PDFs, returned Mime types are one of: text/html text/plain application/pdf (only a few come back as application/pdf) If I explicitly add: .pdf application/pdf File to the type_map property, it will change the Mime types for a few - but only a few - of the PDFs that were coming back wrong. For the most part, the PDFs still get served with the wrong Mime type. Thoughts? --- Edward J. Pollard, B.Sc Webmaster, University of Lethbridge

Hi ! I have a Zope site in Windows. I want to create an automation installer that copy Zope, set some things in ODBC/filesystems, and after start zope.

Thanx for help: ft

Is there a python function that I can use to detect if a substring exists anywhere within another string? I did not come across anything in the Python string module that would allow me to do this. Any help would be appreciated. - Asad

I didnt look @ the zopetree project yet but I experimented with some tales (zpt?). I created an page template witht he following code: <select> <option tal:repeat="sales_tree here/sales_tree/objectValues" tal:attributes="value sales_tree/getId" tal:content="sales_tree/getId"></option> </select> this renders an select box with the objects in the sales_tree folder. But when i try to add this template to the form using the tales tab it gives some errors... or i dont understand the meaning of this tab or the form doesnt understand what i want... -----Original Message----- From: David Convent [mailto:david.convent@naturalsciences.be] Sent: dinsdag 8 maart 2005 13:28 To: Somhorst JJT Cc: 'zope(a)zope.org' Subject: Re: [Zope] using DTML-tree within formulator I personnaly use ZopeTree for that purpose http://www.zope.org/Members/philikon/ZopeTree HTH, Somhorst JJT wrote: >Hello All, > >For a project i need to use formulator.

Security exception after going from 2.6.2 -> 2.7.3
by Jean Jordaan 08 Mar '05

08 Mar '05

Hi all I kinda fear that this is a FAQ, but Google hasn't helped. We have some code that worked fine under Zope 2.6.2, but is raising an exception now: Unauthorized: The container has no security assertions. Access to None of IISet([-994264300, -570961636, -570961635, -164488020, -25364235]) denied. This is the edited traceback:: * Module Products.PageTemplates.ZRPythonExpr, line 47, in __call__ __traceback_info__: here.reservedcustomernumberrange_listing_items() * Module Python expression "here.reservedcustomernumberrange_listing_items()", line 1, in <expression> [...] * Module None, line 13, in reservedcustomernumberrange_listing_items <FSPythonScript at /creme/reservedcustomernumberrange_listing_items used for /creme/Setup/ReservedCustomerNumbers> Line 13 * Module AccessControl.ZopeGuards, line 211, in next * Module AccessControl.ZopeGuards, line 224, in guard * Module Products.VerboseSecurity.VerboseSecurityPolicy, line 157, in validate The code that raises the exception is:: rids = context.QueryService(meta_type='ReservedCustomerNumberRange') result = [context.Catalog.getobject(rid) for rid in rids] # Exception! As is apparent from the traceback, QueryService returns an IISet:: from BTrees.IIBTree import IISet [...] result = IISet() [etc] Any pointers please? -- Jean Jordaan http://www.upfrontsystems.co.za

Packing Zope Database
by Brian Sullivan 07 Mar '05

07 Mar '05

I have a Zope instance -2.7.1 running on Win2000. A Plone instance on it has reached a fairly large size and but is no longer needed. I would like to archive the Plone site, delete it, pack the data base and continue. I currently do not have enough hard disk space to pack the ZODB (as room for the back up and current is required). How much space do I need on the hard disk housing the instance after I delete the Plone instance? Will I be able to pack the data base after deleting the large Plone site ?(assuming the new size is less than the space available naturally). I think I will and all will go well but I thought I would check to see if my thinking is correct. Thoughts?
