[Zodb-checkins] CVS: Packages/bsddb3Storage - BerkeleyBase.py:1.6

[barry@digicool.com]

Update of /cvs-repository/Packages/bsddb3Storage
In directory korak:/tmp/cvs-serv5947

Modified Files:
	BerkeleyBase.py 
Log Message:
tpc_vote(): For the benefit of Zope distros 2.3.1 or earlier, we need
to override BaseStorage's tpc_vote().  This isn't necessary for any
subsequent Zope distributions, because BaseStorage has grown an
identical tpc_vote.
