[GSoC] Update: Week 5

SUMMARY OF MY PROJECT:

Git submodule subcommands are currently implemented by using shell script 'git-submodule.sh'. There are several reasons why we'll prefer not to use the shell script. My project intends to convert the subcommands into C code, thus making them builtins. This will increase Git's portability and hence the efficiency of working with the git-submodule commands. Link to the complete proposal: [1]

Mentors: Stefan Beller <sbeller@google.com> Christian Couder <christian.couder@gmail.com>

UPDATES:

Following are the updates about my ongoing project:

1. sync and status: The patches were discussed with the mentors
   and after that, are being posted with this patch.

2. deinit: The patch is finally debugged, and is ready to be
   discussed. It is also attached with this update.

3. summary: While porting the subcommand, I underwent certain
   issues. After getting them clarified from my mentors, I
   have resumed working on it. I'm aware of the time I have
   taken for porting this subcommand is more than the previous
   ones. Hence will try my best to finish this in this week.

4. foreach: As stated in the previous update, the subcommand was
   ported without resolving the bug, and simply translating the
   present code, and adding a NEEDSWORK tag to the comment for
   mentioning the reported bug as well.
   But as communicating between child_process is still an issue
   and so there was no simple was to current carry out the
   porting. And hence, a hack was used instead. But after
   discussing it, instead using the repository-object patch
   series will help to resolve these issues in this situation.

PLAN FOR WEEK-6 (20 June 2017 to 26 June 2017):

1. summary: Mostly I'll be working on this and post the patch
   for discussion as soon as possible.

2. foreach: As it was decided that unblock the conversion of
   this submodule subcommand, the original cmd_foreach was
   ported without including the BUG-FIX patch here.
   Hence, for this week I will try to utilize the
   'repository-object' series by Brandon Williams.

3. deinit: I will be working on improvising this patch as it was
   recently debugged and posted for discussion.
