Serhiy Storchaka added the comment: Implementing only .__get/setstate__() doesn't fix all problem. We have implement also __getnewargs_ex__(). But implemented __getnewargs_ex__() has priority over __getnewargs__() implemented in subclasses.
And may be there are problems with other optional special methods that are incorrectly delegated to the stream in codecs IO classes. I think more reliable way is to disallow delegating all special (or may be even private) methods. Here is a patch. ---------- assignee: -> serhiy.storchaka nosy: +serhiy.storchaka stage: -> patch review type: enhancement -> behavior versions: +Python 3.5, Python 3.6 -Python 3.3 _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue6395> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
