Hi all! The zope list don't work properly for me for 2 days ago with my normal account garito(a)sistes.net I send several messages (as you could see here: http://tech.groups.yahoo.com/group/zope/message/166174 and here: http://tech.groups.yahoo.com/group/zope/message/166152) but both were lost for me (don't came back to my box) I try to send some message to ask at zope-owner(a)zope.org and jim(a)zope.orgbut nothing in response Could anyone help me, please? And what do you think about my original question? Thanks and sorry if these message are repeated for you! -- Mis Cosas: http://blogs.sistes.net/Garito

adding objects to a ZCatalog
by Tom Von Lahndorff 24 Feb '07

24 Feb '07

Hi, I have a folder called "images" and a form that to add images to that folder. The form called an external method (../images/addImage) that references a python script, the one I sent earlier, that creates 4 versions of the images in 4 sizes and places them in the "images" folder. Also in the "images" folder I have a ZCatalog called "ImageData". I'm trying to add a line to the python script to automatically catalog any images that are added to the "images" folder. I tried "ImageData.manage_catalogObject..." but I kept getting back: NameError: global name 'ImageData' is not defined. Any advice? Thanks. Tom

Zeo Client Hanging Unresponsive
by Paul Williams 23 Feb '07

23 Feb '07

I have posted this several times, but have not until now been able to get DeadlockDebugger installed. zope 2.9.5 + zeo pythonm2.4.3 Red Hat RHEL 4 Plone 2.5.1 Our zeo clients hang intermittently. We have no way of reproducing the problem, but it occurs daily. The client hangs and a restart seems to fix the problem. In the event log with tracing on we get Trace zeo.zrpc.Connection(C) wait(16697) {server:8100} pending, async=0 There are hundreds to thousands of these until the server is restarted. In the zeo log we get Error caught in asyncor asyncore.py error:(110,'Connection timed out') We have been trying to track this down and have had no luck. Does anyone have any suggestions? Below is our deadlock debugger output Threads traceback dump at 2007-02-23 15:26:50 Thread -1269564496 (GET /VirtualHostBase/https/soawds:443/VirtualHostRoot/Content///training): File

Error Tracing in Zope 2.6
by David VanKirk 23 Feb '07

23 Feb '07

Can anyone give me some pointers on tracing errors in Zope 2.6? I'm already using the DTML var "error-tb" or whatever it is. And that can be helpful at times. But I was wondering if there's some other way to pinpoint which line in the DTML file is throwing the error. I'm moving my Zope setup from Linux to Windows and apparently there are some syntax that needs to change when migrating over (aside from my SQL command, since I'm going from Oracle to MS SQL Server). Some of these files are big, and there's a done of files to go through, so going through by hand is just not an option. If anyone can give me some pointers to more specifically locate erroneous lines, or if you can give me some tips on what syntax to look out for during the migration, I'd really appreciate it. -- David VanKirk

Resizing an Image with PIL via a Form Upload

How to create a global variable?
by jerome prudent 22 Feb '07

22 Feb '07

Hi! I've a python script which creates a dictionnary each time it's called. This dictionnary is always the same. I would increase the performance if I could generate and cache the dictionnary once, then reuse it. I'm looking for a space like REQUEST.SESSION that is the same for each user of my website (other solutions are welcome). Do you know how to do that? Thank you.
