Oh, I just mentioned to corner case to say that it would nice to expose the length of a selector. >> What do you think of having some mapping methods? >> >> - iter(selector), selector.keys(): : iter(self._fd_to_key), iterator on file >> descriptor numbers (int) >> - selector.values(): self._fd_to_key.values(), iterate on SelectorKey objects >> - selector.items(): self._fd_to_key.items(), iterator on (fd, SelectorKey) >> tuples > > I don't know, it makes me uncomfortable treating a selector like > a plain container. I don't know if there is a real use case. >> By the way, is SelectorKey.fileobj always defined?

Oh, selector.register(0).fileobj gives me 0... I didn't know that 0 is a file object :-) I would expect .fileobj=None and .fd=0. ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue19172> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
