Raymond Hettinger <raymond.hettin...@gmail.com> added the comment: It looks like somewhere in your application a deque object is being passed where a socket was expected. The easiest way to find the culprit is to edit the class SocketIO in Lib/socket.py:
def __init__(self, sock, mode): if mode not in ("r", "w", "rw", "rb", "wb", "rwb"): raise ValueError("invalid mode: %r" % mode) io.RawIOBase.__init__(self) self._sock = sock + assert not isinstance(sock, deque) ---------- nosy: +rhettinger _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue31591> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
