[Sugar-devel] [GSoC] Porting To Python3

[Gonzalo Odiard]

I agree with Daniel.
We can't break compatibility again now.
The port from gtk2 to gtk3 was inevitable (needed to support touch devices,
and because some libraries like evince)
but at the time, required a huge amount of work,
without apparent benefits for the users (an a few regressions)
You need remember our code is not only Sugar core,
but the hundred of activities with different grades of maintainer support.
Then,  possible plan could be:
* Research changes needed to make the code compatible with python 2 and
python 3
* Prepare a test mechanism (applicable to core and activities)
* Research and if possible port telepathy-python to introspection. Bonus
points if testing is possible.
* Make core and toolkit compatible with python 2 & 3
