This means that the latest modification for this object
lies before the respective transaction.
In this case, we should not have an invalidation for the object,
such that we would not call "_setstate_current".
I expect a missing "flush_invalidations" during "Connection._setDB".
I had to add such a call in our ZODB version:
def _setDB(self, odb, mvcc=None, txn_mgr=DEPRECATED_ARGUMENT,
transaction_manager=None, synch=None):
....
self.transaction_manager = transaction_manager or
transaction.manager
# DM 2005-08-22: always call '_flush_invalidations' as it does
# more than cache handling only
self._flush_invalidations()
if self._reset_counter != global_reset_counter:
# New code is in place. Start a new cache.
self._resetCache()
# DM 2005-08-22: always call '_flush_invalidations'
## else:
## self._flush_invalidations()
