PyGObject 3.3.91 released

I just released PyGObject 3.3.91, for GNOME 3.5.91.

The big new feature in this release (thanks to the release team for granting an exception) is Simon Feltman’s new Signal helper class, which makes defining custom signals a whole lot simpler and more obvious. In the past, you had to do

class C(GObject.GObject):
    __gsignals__ = {
        'my_signal': (GObject.SIGNAL_RUN_FIRST, GObject.TYPE_NONE,
                      (GObject.TYPE_INT,))
    }

    def do_my_signal(self, arg):
        print("my_signal called with %i" % arg)

whereas now this looks like

class C(GObject.GObject):
    @GObject.Signal(arg_types=(int,))
    def my_signal(self, arg):
        print("my_signal called with %i" % arg)

or even more elegantly when using Python 3 and its new type annotations:

class C(GObject.GObject):
    @GObject.Signal
    def my_signal(self, arg:int):
        print("my_signal called with %i" % arg)

Check out the updated example and docstring for other ways how to use it.

Overrides can now be in a directory different from the one that pygobject installs itself into. These overrides need to put this into their __init__.py at the top:

from pkgutil import extend_path
__path__ = extend_path(__path__, __name__)

and put themselves somewhere into the default PYTHONPATH. This should make it a lot easier for library packages to ship their own overrides for Python.

This new version also comes with a couple of new overrides and bug fixes. See the detailled list of changes below.
