Re: [Zope] zopectl does not terminate
Hi Tres! Thanks for the tips. I managed to get my script running in batches and with manual intervention. When in future I encounter the same problems I'll report back to this thread.

Your script has to do the following when interrupted by a ConflictError: - abort the current transaction - sync its database connection (to pick up the changed objects) - re-do the work it was trying to commit (that last 100 updates). > 2.

Re: [Zope] Reconnection session_data to own Session.fs storage
I ran the debug to verify the mount point and got this:
>>> folder.__dict__['session_data']
>>>
And in the session_folder object in the root, the session_data objects
shows as a TransientObjectContainer and not a ZODB Mount Point.

[Zope] zopectl does not terminate
Hi all I run my script foo.zctl with "zopectl run foo.ctl param1 param2". This script operates on a large ZODB and catches ConflictErrors accordingly. It iterates over a set, updates data and commits the transaction every 100 iterations. But I've noticed two things: 1. ConflictErrors are never fully caught. The show up in the console (this is acceptable I suppose), but my script stops executing on the conflict and does not continue. The zope process stays alive. 2. In the event of no conflict errors my script executes its last line (print 'done') but the process does not always terminate. If I instruct my script to not update the ZODB at all it terminates without problems. I'm running it on a live site with 7 ZEO clients. I've stopped a client (say client 2) so it is not accessed concurrently and run my script with client2/zopectl. It is in fact a Plone site but that should be irrelevant.
