Could it be that selecting for *read* on the *write* end of a pipe is always ready? In _UnixWritePipeTransport there's a read handler that immediately closes the pipe as soon as it called. I vaguely remember a discussion on python-tulip that this might be Linux-specific behavior. (The reason is that otherwise you can't find out whether the other end was closed unless you attempt to write to the pipe.) To test this theory, it should be sufficient to comment out line 280 self._loop.add_reader(self._fileno, self._read_ready) from unix_events.py. This will make test_subprocess_kill() hang but it should not affect test_subprocess_interactive. (So it is not a fix, just a way to confirm the theory.) ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue19293> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
