> Adam & I are now on #python-dev. Can you join? I think we successfully resolved this. Adam Olsen will produce a patch that allows one to specify a single file descriptor to which a zero byte will be written by the C-level signal handler. Twisted and PyGTK will have to coordinate about this file descriptor. Glyph believes this is possible and sufficient.
(A preliminary version of the patch may be found here: http://dpaste.com/27576/ ) We considered two alternatives: (a) A patch by myself where the file descriptor would instead be passed together with a signal handler. This was eventually rejected because it places an extra burden on every piece of code that registers a signal handler. (b) A more elaborate patch by Adam which would allow many file descriptors to be registered. This was rejected for being more code and solving a problem that most likely doesn't exist (multiple independent main loops running in different threads). We also located the exact source of the 100 msec timeout in PyGTK: http://svn.gnome.org/viewvc/pygtk/trunk/gtk/gtk.override?annotate=2926 line 1075: *timeout = 100; The recommendation for the OLPC XO project is to remove this line or make the timeout much larger, as the only reason why this was even added to PyGTK is wanting a fast response to ^C from the console, which doesn't represent a viable use case on the XO. -- --Guido van Rossum (home page: http://www.python.org/~guido/) _______________________________________________ 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
