[Zope-dev] session problem again?

[Matteo Memelli]

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

Hmm..

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 at 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).

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?

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
