I just released a new pygobject version 3.1.92, for this week’s GNOME 3.3.92. This was my first-ever GNOME release (yay!), so please bear with me.

One highlight of this release is the new pygtkcompat module, contributed by Johan Dahlin. It provides backwards compatibility to pygtk far beyond to what the Gtk overrrides do, and also includes some shims for the old static webkit, gudev, and other modules. You can, and have to, enable them individually:

import gi.pygtkcompat

# enable "gobject" and "glib" modules
gi.pygtkcompat.enable()
gi.pygtkcompat.enable_gtk(version='3.0')

import glib
import gtk

Now you can use gtk.Window(), glib.timeout_add() etc. as before, and these will be transparently be converted into their modern GI counterparts. Please note that this is still in its infancy, and also mostly meant to ease the porting to GI. It’s not something we’ll keep forever.

Thanks to Michel Dänzer this release now also works properly on big-endian machines.

I mostly worked on fixing the calls of methods which take a list of GValues as arguments, such as Gtk.ListStore.insert_with_valuesv() and similar functions, and made the override API for tree models (append() etc. with providing row data) atomic wrt. the signals it sends out.

I want to thank Johan and Paolo for the nice teamwork with reviewing each other’s patches. That’s open source at its best!
