For now there are no such classes in the stdlib. No one implements __getnewargs_ex__. But an alternative implementation of pickling for methodcaller could use it (I implemented methodcaller pickling in issue22955 in different way, via __reduce_ex__, but used the same trick for passing keyword arguments to constructor). Note that multiprocessing uses default protocol 3 (issue23403), and this is not configurable. ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue24164> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
