Re: Another question about sessions and EditingContexts (sorry)

Dear Sébastien,

Yes, actually I have time to do some testing in a test environment (no production) with sqlite and Postgresql. (And I'm sorry I couldn't help you with python metaclasses in the past.) I'm also very interested in optimistic locking. 

With best regards, 
Erny

  This is the case in every multi-ECs environment, including Zope and
  ZECSessioning.

I currently have the intention of solving that longstanding issue of
synchronizing ECs --and this is a prerequisite for optimistic
locking. Would you have some time testing patches on that topic?
