Hi there, can someone point me to a reference for writing queries for zcatalog in python. I have not been able to find anything that doesn't assume I'm using ZMI or DTML. All hints gratefully received.... Thanks

Debian zope 2.6.2 hangs & solution
by Gabriel Wicke 08 Dec '03

08 Dec '03

Hi, there's a bug in the debian zope package that causes it to hang when running zopectl logrotate for the sixth time. By default this is done each night, so the hangs are rather frequent. This is a known bug (http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=222443) I've tried the second proposed solution (small modification in asyncore), but it didn't help. The first solution/workaround works for me: edit line 641 in /usr/lib/python2.2/site-packages/ZopeCTL.py: def logrotate(self): # """ # logrotate() -> None # # If instance is running, force it to reopen its log files by sending # SIGUSR2 to its PID. # """ # self.__kill(SIGUSR2) """ restart() -> None If instance is running, restarts it by sending SIGHUP to its PID; in any other case starts the instance. """ if self.isrunning(): self.__kill(SIGHUP) else: self.__start() This just restarts zope with SIGHUP instead of sending it a SIGUSR2. Hope this helps somebody Gabriel

zope 2.6.2-2 debian
by John Griessen 08 Dec '03

08 Dec '03

I am attempting to start zope 2.6.2-2 with zope-cmf 1.3.2-1 zopectl 0.2.6 and get connection refused at http://localhost:9673 root@toolbench:/etc/zopectl# /etc/init.d/zope restart Restarting Zope instance default... Waiting instances in late: default(0), done. Could this be a good install, but needs content before it will reply? all howtos I find say I will get a quickstart page if I get this far, so I have been looking at the install steps...for problems. permissions problems withthe debian package seems likely. I get: root@toolbench:/etc/zopectl# ps ax | grep zope 13139 ? S 0:00 gvim zopectlrc 14059 ? S 0:01 /usr/bin/python2.2 /usr/lib/zope/z2.py -l /var/log/zope/default/Z2.log --pid /var/run/zope/default/Z2.pid -f 8021 -p /var/lib/zope/cgi-bin/default -u zope -M /var/log/zope/default/Z2-detailed.log -z /usr/lib/zope -w 9673 INSTANCE_HOME=/var/lib/zope/instance/default SOFTWARE_HOME=/usr/lib/zope/lib/python 14816 ?

Objects in transaction-Object do not support absolute_url() (was: Re: [Zope] Catch Object Changes)

In the transaction-Object I can find the affected Objects of the TA (in the "_objects"-List I think) ... But I cannot get the absolute URL of the affected Objects (cannot use obj.absolute_url()), I think this is because the objects in the transaction-object are not acquisition wrapped, are they? Is there a chance to get the path to the object? -- Thanks, Holger

Empty for me means that it is not interesting to use that index for search (ex: put nothing on that field). Is useful to have a search interface that return nothing? :) I know keywordindex has problem, I've found few example in the web :) ________________________________________________ Message sent using ALFANET Caorle WEBMAIL 1.0

Moving the Data.fs
by Jørgen Larsen 07 Dec '03

07 Dec '03

Hi, I'm trying to setup a ZOPE test environment so I can test my ZOPE stuff before it is installed on the production server. The production environment is running on a Linux box and my test environment is running on a WindowXP machine. I copied the Data.fs and Data.fs.index from the production env. to my test environment - started the ZOPE server - and everything almost seems okay ;) but... When I try to edit one of my objects (named: resource) I get this ZOPE error: Error Value: [Errno 2] No such file or directory: '/usr/lib/zope/lib/python/Products/Localizer/resEdit.dtml' (this is where the dtml file is located on the linux production env.) The resEdit.dtml is located at 'C:\Program Files\zopelocalizer\lib\python\Products\Localizer\resEdit.dtml' in my test environment. How do I fix my the path problem? Do I have to traverse through the tree and change an 'edit path' attribute on my objects? Or? Sorry if this is a stupid question but I am new to ZOPE. Best Regards Jørgen Larsen http://jorgen.larsen.name/

by Andreas Jung 07 Dec '03

07 Dec '03

I have just released TextIndexNG 2.04 which fixes a critical problem in the ranking code which came up with some changes introduced in V 2.03 which has been released last week). V 2.03 user should upgrade to 2.04 as soon as possible. V 2.02 users are not affected but should upgrade to V 2.04 if possible to benefit from the changes in the reindexing code.

When the param is a record, around line 95, I've added: if keys == ['']: keys = None Is it correct? Seems to work with all indexes I've and KeywordIndexes, which works also with AND as operator. ________________________________________________ Message sent using ALFANET Caorle WEBMAIL 1.0
