[Zope-dev] ZODB thread safety issue.

[Romain Slootmaekers]

Yo,
I read on the doc's :
"""
A key feature of Zope 2 (ZODB 3) is that (a copy of) a persistent object
is never accessed by more than one thread (unless the programmer goes way
out of thier way). Each thread uses it's own database connection(s). Each
connection has it's own copies of persistent objects. This feature
provides a major simplification for application developers.
"""

This explains the problems we have with our system:
we have a multithreaded system where each thread iteratese over a set of
objects in the ZODB, and sees of something needs to be done... if so the
thread does it. Now since each thread gets its own version of the object.
our actions occur multiple times... 


This is not the desired behaviour.
Is there a way we can share the access to the objects, or do we have to
create a global lock ? And if we have to create a global lock, what's the
desired/standard approach in doing so.

TIA,

Sloot.
