Update of /cvsroot/python/python/dist/src/Objects
In directory usw-pr-cvs1:/tmp/cvs-serv14033/Objects
Modified Files:
Tag: release22-maint
typeobject.c
Log Message:
Backport, at the reqest of Kevin Jacobs:
- Changed new-style class instantiation so that when C's __new__
method returns something that's not a C instance, its __init__ is
not called. [SF bug #537450]
XXX This is arguably a semantic change, but it's hard to imagine a
reason for wanting to depend on the old behavior. If problems with
this are reported within a week of the release of 2.2.2 beta 1, we may
revert this change.
