The distinction is not needed by IOCP. I am also not too sure that running tulip on WSAPoll() is a good idea, even if the select module provides it. OFF-TOPIC: Although it is not the optimal way of running tulip with IOCP, I have managed to implement IocpSelector and IocpSocket classes well enough to pass tulip's unittests (except for the ssl one). I did have to make some changes to the tests: selectors have a wrap_socket() method which prepares a socket for use with the selector. On Unix it just returns the socket unchanged, whereas for IocpSelector it returns an IocpSocket wrapper. I also had to make the unittests behave gracefully if there is a "spurious wakeup", i.e. the socket is reported as readable, but trying to read fails with BlockingIOError. (Spurious wakeups are possible but very rare with select() etc.) It would be possible to make IocpSelector deal with pipe handles too. ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue16507> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
