Serhiy Storchaka added the comment: All public classes not designed for pickling explicitly. I tested only operator.methodcaller, mmap.mmap, sqlite3 classes (Connect, Cursor, Row), _socket.socket, select.epoll, _csv.Dialect, but should be more. Instances of these classes can be "pickled", but unpickling either raise an exception (usually TypeError), or returns default or underinitialized object.
For other classes the patch changes raised exception type. E.g. pickling zlib.compressobj() raised _pickle.PicklingError: Can't pickle <class 'zlib.Compress'>: attribute lookup Compress on zlib failed and with the patch it raises TypeError: can't pickle zlib.Compress objects ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue22995> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
