Thanks alot. I didn't realise you could do this within the RewriteRule directive. Cheers.

Some installation glitches
by Dennis Allison 18 Apr '06

18 Apr '06

64-bit machines (dual dual-core AMD Opteron) First: Configuring Zope installation Using Python interpreter at /usr/local/bin/python2.4 /usr/local/bin/python2.4 install.py -q build Dependencies/ExtensionClass-Zope-2.9.2/ExtensionClass/_ExtensionClass.c: In function `PyExtensionClass_Export_': Dependencies/ExtensionClass-Zope-2.9.2/ExtensionClass/_ExtensionClass.c:768: warning: cast from pointer to integer of different size /usr/local/bin/python2.4 install.py -q build /usr/local/bin/python2.4 install.py -q install --skip-build --home "/usr/local/src/zope/Zope2.9" _ExtensionClass is not 64-bit clean. I believe the warning can be ignored. When I install Zope 2.9.0 on a 64 bit machine the path to the system is .../Zope/lib64/python/... but with Zope 2.9.2, also on a 64-but machine the path to the system is ...Zope/lib/python/.... Why the change? --

RE: No memory leak! (was: Re: [Zope] Memory Leak in Session Data Container)
by Andy Yates 18 Apr '06

18 Apr '06

Leak, bug, improper configuration, what ever. ;-) With the onDelete in place for 1 week now I checked the temporary Cache Parameters as you requested. Since I put the onDelete on this server memory use has still grown, but at a much slower rate. I think it will go about 10 days like this instead of 1 before using up all system memory. For whatever reason we have 7 caches on this server. I do not see where this is configured. /Control_Panel/Database/temporary/manage_cacheParameters Total number of objects in the database 363761 Total number of objects in memory from all caches 34952 Target number of objects in memory per cache 5000 I flushed the cache and about 1 hour after flushing, memory use has not gone down at all. During that hour objects in all caches went from 0 to 15341. Objects in the transient object container are still holding steady at 2000-3000. Before the onDelete they grew without bound. /Control_Panel/Database/temporary/manage_cacheParameters Total number of objects in the database 369885 Total number of objects in memory from all caches 15341 Target number of objects in memory per cache 5000 It seems odd to me that the total objects in the db are growing so large. If I understand you correctly a workaround would be to change the number of objects per cache from 5000 to something more reasonable. Where is this configured and what is reasonable? 5, 50, 500. I do not see an item for this in the config file. Should there be any cache at all on an in-memory temp db?

DELETE Objects
by Erik Billing 18 Apr '06

18 Apr '06

I want to create a python script that deletes a specific file from a folder. For now, the user who is calling the script does not have the Delete objects permission on the folder, only the file which he should be able to delete. I have previously used the delObjects method on the folder to remove the file, but this requires the Delete obejcts permission on the folder itself. I would like to do something like container[entry_id].DELETE() but the DELETE method requires 3 arguments, and I dont know what to give it? Or is it better to go in the delObjects on the container and use a proxy to solve the permission problems? Best regards /Erik

Export html
by BKJ＠telefonica.net 18 Apr '06

18 Apr '06

Hello, I have an archetype, I want to export the html that I see in the view mode to a rtf (or similar) format. I tried to use the product "RTFExport" but it doesn't export from HTML (or I don't know how to do this). I have found the product "PloneOOoTransforms" , does anybody have experience with this product? Can this product export the html of the view mode to another format. Thanks (I apologize If I've been using the wrong list to post this question) TERRA -->

rss republishing
by David Bear 18 Apr '06

18 Apr '06

I have a plone intranet site running on box A. I have a public web server, running apache on box B. I would like to have a plone topic published as an rss feed, which Box B republishes for clients. I don't want the clients to know the pages originate on box A. I would like them to appear from box b -- and even cached for a period of time. Are there any zope products that might help with these? or an apache module if there apache experts here. I might even entertain an mod-python module if something like it existed. -- David Bear What's the difference between private knowledge and public knowledge?

what process does Zope run as?
by Lars Hohmuth 18 Apr '06

18 Apr '06

What process does Zope run as in Windows XP? I finally tracked down the 10053 errors in Plone's MailHost down to port blocking in one of McAfee's virus scanners. But neither enabling port 25 for python.exe, java.exe, or pythonservice.exe seems to work. Getting rid of the port 25 blocking does, but that gives my sysadmin fits. Thanks, Lars
