Update of /cvsroot/python/python/dist/src/Lib/test
In directory usw-pr-cvs1:/tmp/cvs-serv27530/Lib/test
Modified Files:
Tag: release22-maint
test_descr.py
Log Message:
Backport to 2.2.x:
Address SF bug 519621: slots weren't traversed by GC.
While I was at it, I added a tp_clear handler and changed the
tp_dealloc handler to use the clear_slots helper for the tp_clear
handler.
Also set mp->flags = READONLY for the __weakref__ pseudo-slot.
[Note that I am *not* backporting the part of that patch that
tightened the __slot__ rules.]
