Cookie Crumbler/Authentication Question
by Palermo, Tom 19 Apr '06

19 Apr '06

All, I am working on a site that uses CookieCrumbler for the authentication. Part of this site allows a user to change their password via this line: userfolder.manage_users(submit='Change', REQUEST=user_info). This works fine except after changing the password, the user is no longer authenticated and an Unauthorized exception is raised. Is there anyway to automatically keep the user logged in or re-authenticate them. Thanks, Tom Palermo

Custom 404 - Resource not found
by Andy Yates 19 Apr '06

19 Apr '06

Is there a way to customize the Zope 404 error page? Site Error An error was encountered while publishing this resource. Resource not found Changing standard_error_message does not seem change this error page. I need to do this inside Zope or via the apache front end which talks to Zope through mod_rewrite/proxy and Virtual Host Monster. Thanks! Andy

Re: [Zope] Getting www.domain.com:8080/manage to go through Apache

Ok, good to know that. So if I get this right I add in _vh_manage to the VirtualHostRoot in Zope which will cause /manage/ to be appended onto the all the URLs within Zope. The correct pages will still be served and the Apache re-write rule will be satisfied...

Re: [Zope] DELETE Objects
by Erik Billing 18 Apr '06

Ok. Thanx. But why is it like this? I imagine that deleting an object in a folder where I do not have permission to delete every object, or the folder itself, is a quite common task. Using the manage_delObjects and a proxy really feels like I'm fighting the zope security instead of getting support by it. Or am I thinking wrong in the first place? What I really want to do is letting users answer a question object and the answers should be stored somewhere. A user must later be able to change or remove his answer, but of course not the answers of any other user. I place all answers objects belonging to a certain question in one folder, and I have the previously mentioned situation. I know it is not that much of a problem to use a proxy, but if I can change my design in some way so can avoid the proxy I imagine that would be better. /Erik On 4/18/06, Andreas Jung <lists(a)zopyx.com> wrote: > > > > --On 18.

The Plone people have an "epidoc" documentation online (I do not have the url at hand, you have to search for it).

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

Some installation glitches

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
