select() works with sockets. But nothing else if you want to stay cross-platform, so async file IO and other things remain open questions. By the way, you don't need clumsy polling to wait for helper threads ;) You can just use a ConditionVariable from the threading package (or something else with the same semantics). BTW, I'm not arguing at all for the extension proposal. Integrating async stuff into generators does not need an API extension IMO. I'm already doing it in my scheduler. An example which just waits for an external command to finish and periodically spins a character in the meantime: http://svn.berlios.de/viewcvs/tasklets/trunk/examples/popen1.py?view=markup The scheduler code is here: http://svn.berlios.de/viewcvs/tasklets/trunk/softlets/core/switcher.py?view=markup Regards Antoine. _______________________________________________ Python-Dev mailing list Python-Dev@python.org http://mail.python.org/mailman/listinfo/python-dev Unsubscribe: http://mail.python.org/mailman/options/python-dev/archive%40mail-archive.com
