Commit c39d5c67 authored by Julien Muchembled's avatar Julien Muchembled

Add support for latest versions of ZODB (4.4.3 & 5.0.1)

Many patches have been merged upstream :)

A notable change is that lastTransaction() does not ping the master anymore
(but it still causes a connection to the master if the client is disconnected).
parent 13911ca3
Patch to ZODB 4.3.1 for ZODB unit tests.
See also monkey-patch to Connection.tpc_finish in neo/client/__init__.py
