Hello I include the conversation that I had today with Chris:
I'm using Zope 2.6b1+ with ZWarehouse e-commerce product (ZWarehouse-20040522 version 0.8) I tried upgrading to Zope 2.7 but ZWarehouse gave me many problems so I decided to try applying your patches for Sessioning problems that I have.
Hmm..
I think that the error that zope gives to me is very known to you... I tried to copy the whole directories Transience, Session and ZPublisher from both Zope-2.7.3b1-0 and Zope 2.7.2 but without success I also copied the file startup.py from lib/python/Zope/App/ ... Am I missing anything?
Yes, the ZODB directory also... although I reallly have no idea whether this will work under 2.6. Really, to be sure you've got all the right files, it'd be best if you could upgrade to 2.7.3... maybe we could help fix whatever in ZWarehouse doesn't work under there (move this conversation to the Zope list zope@zope.org?) To be thorough, you will also need to delete and recreate any persistent session data container you've got laying around (unless it's in temp_folder, that's in RAM anyway and gets recreated on reboot).
My customer is complaining so much and I really don't know what to do! Hoping in your answer...thank you in advance

Hmmm.. that's an odd place to get that error. I'm surprised. Does it only happen after some period of inactivity on the site? - C FOLLOWING Chris's advice first I tried to copy also ZODB directory from Zope 2.7.3 but still the same error... so I Installed Zope-2.7.3b1-0 (IS THIS THE RIGHT VERSION THAT SHOULD SOLVE SESSION PROBLEMS?) and reinstalled with success the following packages: ZWarehouse 0.8 iHotfix-0.4.0 itools-0.4.6 Localizer-1.1.0a4 ZMySQLDA-2.0.8 MySQL-python-1.0.0 TranslationService-0.4 THEN imported my customer's web site but I still have the same problem... whats going on... what am i missing? For every change I made I delete and recreate any persistent session data container rebooting the server (IS THIS ENOUGH OR MUST I DO ANYTHING ELSE???)
From what I can see it seems that the problem comes after about 20 minutes of inactivity... session timeout? (How can I get the session longer just for now I mean??!! modyfing default value in session_timeout_minutes in lib/python/Zope/Startup/handlers.py ???)
Hoping to solve the problem quickly....my customer is going to kill me otherwise :( Thank you Matte
