Hello all, Python 3 includes a WeakSet implementation. Any objections to me backporting this to 2.7? http://docs.python.org/py3k/library/weakref.html#weakref.WeakSet I needed this in unittest and used a WeakKeyDictionary instead.

Backporting WeakSet would also make it possible to backport the fix for this reference leak: http://bugs.python.org/issue2521 -- Daniel Stutzbach, Ph.D. President, Stutzbach Enterprises, LLC <http://stutzbachenterprises.com>

It should be possible to fix it with a WeakKeyDictionary instead of WeakSet. All the best, Michael Foord

True. I should have said "Backporting WeakSet would make it *easier* to backport the fix ..." :-) -- Daniel Stutzbach, Ph.D. President, Stutzbach Enterprises, LLC <http://stutzbachenterprises.com>

Hmmm... I was under the mistaken impression that this was implemented in pure-Python. It's in C so beyond my threshold for simple porting I'm afraid. Still if someone else is up for it... All the best, Michael

No, my mistake - it *is* implemented in Python. I'm porting it now. Michael
