[Zodb-checkins] CVS: Zope3/src/zodb/code - class_.py:1.7

[Jeremy Hylton]

Update of /cvs-repository/Zope3/src/zodb/code
In directory cvs.zope.org:/tmp/cvs-serv26299

Modified Files:
	class_.py 
Log Message:
Add an __call__() to the PersistentClassMetaClass to guarantee
that instance's __init__() methods are called.

# type's __call__() uses tp_init directly, so it bypasses our
# __getattribute__() hook.  So we must guarantee that a class
# is loaded before it is called.
