[Zope3-checkins] CVS: Zope3/src/zodb/storage/tests - undo.py:1.3

[Jeremy Hylton]

Update of /cvs-repository/Zope3/src/zodb/storage/tests
In directory cvs.zope.org:/tmp/cvs-serv1294/storage/tests

Modified Files:
	undo.py 
Log Message:
Refactor storage interfaces.

Move a bunch of exceptions related to storages from zodb.interfaces to
zodb.storages.interfaces.

Add __implements__ statements in all the concrete storage classes.

Add a simple (good?) mechanism to propagate __implements__ values from
a ZEO storage to its clients.

Remove all use of supportsXXX() methods in favor of
ISomeInterface.isImplementedBy().
