[Zope3-checkins] CVS: Zope3/src/zodb/zeo/tests - cache.py:1.2.8.1 connection.py:1.4.4.1

[Jeremy Hylton]

Update of /cvs-repository/Zope3/src/zodb/zeo/tests
In directory cvs.zope.org:/tmp/cvs-serv6570/src/zodb/zeo/tests

Modified Files:
      Tag: storage-interface-branch
	cache.py connection.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().
