It's not possible to use it with select.select() because on Windows this function only accepts sockets. I don't know if it's possible to watch a pipe using IOCP. Is set_wakeup_fd() used by Twisted, Tornado or another project on Windows? I would like to modify signal.set_wakeup_fd() to make the file descriptor (or socket) non-blocking: see issue #22042. I proposed this change to protect the user against misuse of the API, and to make the API more convinient. asyncore and asyncio modules also make files and sockets non-blocking: asyncore.dispatcher(sock) and asyncio.BaseEventLoop.connect_read_pipe() for example. Oh, by the way, sock_xxx() methods of asyncio.BaseEventLoop don't make the socket non-blocking, and the documentation doesn't require that sockets are already set to non-blocking mode. It looks like a bug (at least in the documentation). ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue22018> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
