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?

Conditional SiteRoot
by Michael.Kaplan＠t-online.de 07 Mar '05

07 Mar '05

Hi Could anybody tell me how to install a conditional SiteRoot (I would like the SiteRoot only for anonymous users)? Background: I'm running Zope/Plone behind Apache and use ProxyPass and SiteRoot to get some subdirectories from Zope, while the rest of the subdirectories are standard html-pages delivered by Apache. To accelerate this system, I use Apache's mod_cache. This works fine and gives some extra speed. The users see the cached pages under http://mydomain/foo/bar and Plone-Members can login and admin at the system at http://mydomain/extraprefix/foo/bar But if a user now logs in and enters http://mydomain/extraprefix/foo/bar with the SiteRoot, he is redirected to http://mydomain/foo/bar cached by Apache and therefore there is no more Plone-line to edit the page etc. Therefore I had to switch off the cache again. Thanks a lot in advance for any help Michael

February Bug Day Roundup
by Chris Withers 07 Mar '05

07 Mar '05

Hi All, Ug, looks like things went from bad to worse. January's bug day was very quiet, February's was totally dead. Not a single issue was dealt with on the bug day and #zope-dev was dead for the whole day. I'm going to take a break from running bugdays for a few months since I guess we're suffering from bug-day-overload... cheers, Chris -- Simplistix - Content Management, Zope & Python Consulting - http://www.simplistix.co.uk

logging inside TTW script
by Milos Prudek 07 Mar '05

07 Mar '05

Hi, How can I log events that take place inside a TTW Python Script, and log them immediately? I have a script that converts a few hundreds of objects in a "for" loop. One of these objects causes my script to fail. I need to find out which object it is. In other words, which iteration. TTW scripts of course runs is a single transaction for Zope, and if anything fails, Zope will discard the whole transaction and not tell me which iteration the problem was in. If I put logging in the TTW script, it will not help, because the logging itself will be discarded too! Please help. -- Milos Prudek

ZSQLRelayDA
by jamie＠textmatters.com 07 Mar '05

07 Mar '05

I'm trying to use ZSQLRelayDA to access a MS SQL database on a windows server from a Zope instance on a linux server. I can issue one query, then I get an error printed to the console of the linux box when I try to issue another: "Client Library error: severity(78) layer(0) origin(0) number(51) Error: Attempt to initiate a new SQL Server operation with results pending." Zope hangs, and needs to be restarted. It looks like either zope or sqlrelay isn't closing the database connection properly. Anyone any ideas of how to fix this? Robert Munro
