Take a look at the THREADS file in the pygtk directory, which describes some of the problems. Having either a free threaded python or recursive interpreter lock would make things a lot easier to implement.

It's not obvious to me why pygtk needs to support the Glib/Gtk thread model if Python's is available already.

Sopwith produced a patch (which was a bit of a hack) to support threading. Given the current schedule, we should probably put in some threading support based on these patches. This support will probably be turned off by default, but be possible to turn on at runtime (this is to mirror gtk+, where threading must be explicitly enabled with the gdk_thread_init() call now). It will most likely look something like: import gtk gtk.enable_threads() I have slightly modified zilch's threads disable patch on the stable branch (this is is a way to get round the applet/dialog deadlock problem someone was experiencing recently), to make it more convenient. Now, you can do: import gtk gtk._disable_gdk_threading() (this uses a hack suggested by owen, of setting gdk_thread_mutex to NULL after initialising gtk in order to disable gtk thread support).

[pygtk] Pygtk 1.99 and threading.
I'm using python 2.2b1, pygtk 1.99.5 and gtk 1.3.11. If i compile pygtk with --enable-thread then pygtk programs simply crash immediately with a segfault. without threading they work fine, but i need threading support. is there a way of getting the nice tasty threads_enter/ leave() thing that pygtk 0.6.x had, or any way of using threading? -- Tom "Moretom" Morton (www.moretom.net) ___ pygtk mailing list [EMAIL PROTECTED] http://www.daa.com.au/mailman/listinfo/pygtk
