[GSoC][PATCH 00/13] Update: Week-12


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.

Following are the updates about my ongoing project:

* Following patches were updated after the previous reviews:
  submodule subcommands:
  - deinit
  - summary
  - foreach

* summary: the function print_submodule_summary() is split-up
  into two separate functions: generate_submodule_summary()
  and print_summary().

* porting of submodule subcommand 'add' is completed and I have
  started with debugging ported function. Currently, the
  entire function cmd_add() is ported to the function
  module_add() in C. Soon, its first patch will be floated
  here as well once debugging is completed. Its progress can be
  viewed at [2].

* displaypath: Last week, there was some confusion produced
  with the way, the value of displaypath is being generated,
  which led to some discussion, which is available at: [3].

PLAN FOR WEEK-13 (8 August 2017 to 14 August 2017):

* patches: IMO, the patches till deinit are reviewed many times,
  and hence will try to get at least these patches merged.

* add: As this subcommand is widely used in the test suite, there
  are many tests this ported function is failing at. Hence,
  debugging the subcommand would be another task for the next week.

* deinit: A bug was identified by Stefan in the last patch-series.
  its details are available at: [4]
  Currenlty, the bug was handled by adding a NEEDSWORK tagged
  comment as suggest. If possible, I will also start working
  on debugging the issue asap.

A complete build report of these series of patches is available at: [5].
Build #151
Branch: week-12

The work is pushed on Github and is available at: [6].
