Is this a better solution? http://www.zope.org/Members/lucasm/ZCatalogPatch It just modify the url methos to return the phisical path with CatalogAware.

Personally, I use Linux From Scratch (www.linuxfromscratch.org) for all my production systems. Takes longer to build a "distro" but then you get exactly what you want, configured how you want it, and without all of the baggage. Sean

Zope 2.7b3 & CMF1.4.2 conflict on Win2K and WinXP?
by Marcel Maré 08 Dec '03

08 Dec '03

I have installed a new Zope 2.7.b3 and put the CMF products in the zope-instance/Products folder. Zope then fails to start with this error: Traceback (most recent call last): File "C:\devel\python\Zope-2.7.0-b3\lib\python\Zope\Startup\run.py", line 27, in ? run() File "C:\devel\python\Zope-2.7.0-b3\lib\python\Zope\Startup\run.py", line 24, in run start_zope(opts.configroot) File "C:\devel\python\Zope-2.7.0-b3\lib\python\Zope\Startup\__init__.py", line 50, in start_zope starter.startZope() File "C:\devel\python\Zope-2.7.0-b3\lib\python\Zope\Startup\__init__.py", line 218, in startZope Zope.startup() File "C:\devel\python\Zope-2.7.0-b3\lib\python\Zope\__init__.py", line 46, in startup _startup() File "C:\devel\python\Zope-2.7.0-b3\lib\python\Zope\App\startup.py", line 47, in startup OFS.Application.import_products() File "C:\devel\python\Zope-2.7.0-b3\lib\python\OFS\Application.py", line 512, in import_products import_product(product_dir, product_name, raise_exc=debug_mode) File "C:\devel\python\Zope-2.7.0-b3\lib\python\OFS\Application.py", line 534, in import_product product=__import__(pname, global_dict, global_dict, silly) File "C:\devel\python\Zope-instance\Products\CMFCalendar\__init__.py", line 20, in ? import CalendarTool File "C:\devel\python\Zope-instance\Products\CMFCalendar\CalendarTool.py", line 18, in ? import calendar File "C:\devel\python\Zope-2.7.0-b3\bin\Lib\calendar.py", line 8, in ? import datetime ImportError: No module named datetime I get the same error with CMF 1.4.1 and also on 2 different PCs (2000 and XP). Using CMF1.4.2 with Zope 2.6.1 works fine. Any ideas? TIA Marcel

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

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 ?

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/
