[SoC RFC] about "restartable clone"

[Henry Huang <henry.s.huang@gmail.com>]

Hello Git Team,

I'm a student interested participating in restartable clone project
for this year.
To this time, I have used mainly SVN as version control.
Recently i began to try git -- it is so exciting! :)
When i saw this project in Soc2009Ideas,
i feel it is a appropriate project for me, as this problem i have
experienced a lot:(
-- "Users need to start over from the beginning and try again when the
clone is interrupted in the middle."
i am eager to solve it with my passion and work.

Now i have several problems:

1) Less familiar with git source code
2) Less experience in Open Source Development
3) No proposal for this project

My questions:

1) Are there any documents for git's internals ?-- (.git/ structure,
data structures: DAG of objects,
branches, tags, index etc.) and workflow of main operations
2) Could anyone give me some hints -- where to begin with this project?

At the end, few words about me, what you could expect:
I'm a MSc undergraduate at Nanjing University of Posts & Teles (China).
My main areas of interests are software engineering.
C and Python are my "main" Languages.
so I can analyze existing git implementation.
I have worked on some smaller projects related with protocol
implementation in small teams.
It seems to be great experience if I can join git community:)

Thank you for your attention,
I'd appreciate any comments, expectations or information!

BTW: i have enough free time for doing research and programming on
this project from Feb to Sep.

Any suggestion would be appreciated.

Thanks,
Henry Huang
