[GSoC] Update: Week 7

[Prathamesh Chavan]

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.

UPDATES:

Following are the updates about my ongoing project:

1. sync and status: The patches are updates after the last
   discussion, and will be posted with this update, along
   with the patches of the function get_submodule_displaypath()
   and for_each_submodule_list().

2. deinit: The patch was discussed in the last update, and
   I still have to make the required changes to this patch.

3. summary: I'm still working on debugging this patch as
   the are still some part where the patch isn't working as
   expected.

4. foreach: Most of the time was spent in reading the repo-object
   patch series. Also, currently I'm still confused about the
   approach I have to take for carrying this out.

PLAN FOR WEEK-8 (4 July 2017 to 10 July 2017):

The main focus for this week will be to get the reviewed code merged
by sending new version after their review. Hence, I've attached
the patches which were recently review, after adding the
suggested changes, with this update. Other than that, there is still
lots of work related to porting left as follows:

1. foreach: I'll try to come up with an approach for the present
   problem in the foreach patch, and get this discussed with
   mentors as well as with Brandon Williams so that I can
   get this subcommand ported.

2. summary: Currently, I'm still on debugging the patch. There are
   parts of the patch which aren't running as expected and hence
   it is taking more time to figure it out.

3. deinit: The patch was reviewed in the last update and I'm yet to
   work on the improving the patches as suggested.

Apart from this, there still lie two submodule subcommands: 'add' and
'update' unported.
I'll try to completed as much as work related to porting but will
also, focus on improving the code completed so that it becomes good
for merging.

[GSOC Update] Week 7

[Pranit Bauva]

= SUMMARY ==
My public git.git is available here[1]. I regularly keep pushing my work so
anyone interested can track me there. Feel free to participate in the
discussions going on PRs with my mentors. Your comments are valuable.


=== INTRODUCTION  ==
The purpose of this project is to convert the git-bisect utility which partly
exists in the form of shell scripts to C code so as to make it more portable.
I plan to do this by converting each function to C and then calling it from
git-bisect.sh so as to use the existing test suite to test the function which
is converted.

Mentors:
Christian Couder 
Lars Schneider 


== Updates =
Things which were done in this week:

 * I have converted check_and_set_terms() and have also sent an RFC[2] to the
   mailing list for discussion which hasn't yet collected any comments. It is
   kind of important to discuss this as it uses a way to set the global
   variables in the script by writing it to a file and then reading it.

 * I have also converted bisect_next_check() but this has a bug which will
   soon be fixed. This is available here[3].

 * I have converted get_terms().

 * I am on my way to convert bisect_terms() which should probably finish by
   tomorrow.

 * I also send out a patch[4] which describes the return value of
   strbuf_read_file() and is queued on the pu branch.

= NEXT STEPS 
Things which would be done in the coming week:

 * Finish off bisect_terms().

 * bisect_run().

 * bisect_replay().

 * I have my mid term evaluations this week. Hope I clear it successfully.
