[Zodb-checkins] CVS: Zope3/lib/python/Persistence/tests - testPersistence.py:1.1.2.4

[Jeremy Hylton]

Update of /cvs-repository/Zope3/lib/python/Persistence/tests
In directory cvs.zope.org:/tmp/cvs-serv23904

Modified Files:
      Tag: Zope-3x-branch
	testPersistence.py 
Log Message:
Add __implements__ attribute to Persistent type implemented in C.

Extend test suite to verify that Persistent implements IPersistent and
other tests implied by the first one.

Remove persist_safe() method from cPersistence.c; was obsolete as of
previous checkin.

Add persist_set_interface() that adds __implements__ to type's tp_dict
after the type is initialized.
