Polyglot port of Sugar core
'''Description'''
For sugar to be future ready, it's core has to be compatible with python 3.x . Python 2.7+ would also need to be supported for existing activities to run without a hitch. This would represent developers who prefer python 3 as well as those who prefer python 2.7+ to be able to contribute to sugar.
One approach would be to sort out python 3 support for all the dependencies, and then run 2to3 on the core code and provide a wrap around script that would handle both python 2.7+ and 3 activities. But maintaining the code could turn messy real quick.
My plan of action is to have a single easy to maintain codebase that can run on python versions 2.7 through to 3.3. Towards this end, I would automate tests to run across python2.7 - 3.3 with [https://pypi.python.org/pypi/tox tox] or a similar tool first, and then write polyglot code with [https://pypi.python.org/pypi/six six] incrementally.
My project would introduce no new features at all, but it would make sugar future ready and also backwards compatible. It might make development/maintenance harder on the core libraries in the short term, because the developers would need to understand the polyglot written using six. But it would provide long-term benefits and a wider potential future developer reach.
===Schedule===
'''April 21 - May 19 (Community Bonding Period)'''
* Research into and learn more about gtk and dbus.
* Get familiar with the codebases of sugar and sugar-toolkit-gtk3
* Look into the unit tests and determine if test cases are robust enough to support a porting effort. If required, write test cases with the help of the community and also encourage fellow GSoC-ers and developers to practice TDD.
* Discuss with the core developers and mentor(s) my initial approach I have detailed above and iron out the rough edges or discuss and decide on an alternative approach if need be.
* Research other python projects that were ported with the same approach. Contact the developers and learn about the issues they faced and I'm likely to face while porting.
* Get familiar with Tox or discuss with mentor(s) and choose a different testing framework to automate testing across python versions and get familiar with the same.
* Get to know the mechanisms of the build scripts.
* Bond with the Community. Get to know the developers responsible for writing/maintaining the sugar core, so I know whom to ask for help if I run into trouble.
'''May 19 - June 23 (First half of the official coding period)'''
* Automate testing across python versions using the decided on approach, make all the tests pass on python 2.7.
* Incrementally patch code with six to run on python 3.x and pass unit tests.
* This seems like just a repetitive task, but the codebases seem a little fragile to me as of and I might run into a few issues and these would need some fixing from time to time.
'''Mid-term Evaluation'''
:By this time, I plan to have finished writing polyglot for sugar and sugar-toolkit-gtk3
'''June 23 - August 11(Second half of the official coding period)'''
* Look for and Iron out bugs and patch the bugs with unit tests so they don't pop up again.
* Add python 3.x specific dependencies into the list of things to be fetched and installed by the build scripts.
* When the mentor(s) and the core developers are satisfied with the code and think that the codebase is solid, try and port sugar-build in the same way(if time permits).
'''Deliverables at the end of GSoC'''
* Automated tests across python versions for sugar and sugar-toolkit-gtk3
* Fully python 3 compatible polyglot codebases of sugar and sugar-toolkit-gtk3
* python 3 compatible sugar-build (optionally)
Post GSoC, I would be available to help port activities to python 3.x
* Convince us, in 5-15 sentences, that you will be able to successfully complete your project in the timeline you have described. This is usually where people describe their past experiences, credentials, prior projects, schoolwork, and that sort of thing, but be creative. Link to prior work or other resources as relevant.

===You and the community===
===Me and the community===
* If your project is successfully completed, what will its impact be on the Sugar Labs community? Give 3 answers, each 1-3 paragraphs in length. The first one should be yours. The other two should be answers from members of the Sugar Labs community, at least one of whom should be a Sugar Labs GSoC mentor. Provide email contact information for non-GSoC mentors.

Find help on the mailing list or the IRC, or if that doesn't work out, work on a different part of the project until my mentor is available.
* How do you propose you will be keeping the community informed of your progress and any problems or questions you might have over the course of the project?

I plan to write a report every week on my [http://upman.github.io blog](which has gone cold after a couple of posts) and also discuss with people periodically over the mailing list or the IRC channel.
