Subject: [GSoC][PATCH 1/4] submodule--helper: introduce get_submodule_displaypath()
Date: Mon, 21 Aug 2017 21:45:12 +0530
Message-ID: <20170821161515.23775-1-pc44800@gmail.com> (raw)

Introduce function get_submodule_displaypath() to replace the code
occurring in submodule_init() for generating displaypath of the
submodule with a call to it.

This new function will also be used in other parts of the system
in later patches.

As said in the previous update,
a short patch series is floated for the maintainer's review,
and is consisting of the following changes:
* introduce function get_submodule_displaypath()
* introduce function for_each_submodule_list()
* port function set_name_rev() from shell to C
* port submodule subcommand 'status' from shell to C

The complete build report for the above series of patches is available
at:
https://travis-ci.org/pratham-pc/git/builds
Branch: week-14-1
Build #158
The above changes are also push on github and are available at:
https://github.com/pratham-pc/git/commits/week-14-1

The above changes were based on master branch.
But along with the above changes, the same series was also applied
to a separate branch based on the 'next' branch. The changes were
applicable without any additional changes to the patches.
Complete build report of that is also available at:
https://travis-ci.org/pratham-pc/git/builds
Branch: week-14-1-next
Build #159
The above changes are also push on github and are available at:
https://github.com/pratham-pc/git/commits/week-14-1-next
