Detailed Description

Several of the Python modules we are using right now will become deprecated in the next GNOME release. PyGObject has gained support for GObject Introspection, which will allow us to keep using the GNOME platform without needing static bindings.

Benefit to Sugar

This will reduce overall memory usage and startup time of the shell and activities. Also will make easier use libraries written in languages other than Python.

Scope

Will need changes in about every sugar module, including activities, but we'll have a script that will make it easier. Not all activities need to switch at the same time.

How To Test

Run Sugar and activities as usual, notice startup is faster and check with 'free' the amount of free memory.

User Experience

The shell and activities should start much faster and you can launch more activities before systems with low memory and no swap (like the XO) become unresponsive and crash.

Dependencies

Yes, we depend on work in other GNOME projects: http://live.gnome.org/GObjectIntrospection/ and http://live.gnome.org/PyBank/ .

Contingency Plan

None necessary, revert to previous release behaviour.
