I've been giving thought to implementing the locking on the instance or per instance instead, and there are bad and worse ideas like inserting per (instance, descriptor) into the instance `__dict__`, guarded by the per-descriptor lock; using a per-descriptor `WeakKeyDictionary` to map the instance to locks (which would of course not work - is there any way to map unhashable instances weakly?) So far best ideas that I have heard from others or discovered myself are along the lines of "remove locking altogether" (breaks compatibility); "add `thread_unsafe` keyword argument" with documentation saying that this is what you want to use if you're actually running threads; "implement Java-style object monitors and synchronized methods in CPython and use those instead"; or "create yet another method". ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue43468> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
