I suppose you could run a separate thread that performed this conversion in parallel with other activities. There's a bit of a coordination problem to make sure you're done. It seems other application code would need to use the old class definition until the update was completed, but that means new references can be created while the update is running. So you'd need some sort of coordination to atomically switch from old class to new class when the update was completed.
Maybe I misunderstood. I thought the only issue here was moving the class to a different module. Are you supposing that the class implementation is also changing? _______________________________________________ For more information about ZODB, see the ZODB Wiki: http://www.zope.org/Wikis/ZODB/ ZODB-Dev mailing list - ZODB-Dev@zope.org http://mail.zope.org/mailman/listinfo/zodb-dev
