Carl Meyer added the comment: Uploaded a patch updated per Nick's comment.
Not opposed to waiting to see if someone is motivated to implement a version in C that supports __slots__, but if that doesn't happen by the Python 3.7 feature deadline, I don't think it should block this proven version. It also occurred to me that we could probably support __slots__ in pure Python without harming the non-slots case by implementing a fallback cache in the descriptor itself, keyed by instance in a WeakKeyDictionary. I don't love having the behavior differ so much between the slots and non-slots case, but maybe it's better than not supporting slots at all. Re setting and deleting: under the current patch, if you set or delete a cached property, you set or delete the cached value. I think this is fine and useful behavior, but it could perhaps be added explicitly to the documentation. ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue21145> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
