[GSOC Update] Week 5

[Pranit Bauva <pranit.bauva@gmail.com>]

================================= 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 <chriscool@tuxfamily.org>
Lars Schneider <larsxschneider@gmail.com>


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

 * bisect_clean_state() function is converted and I have fixed the
   segmentation fault. I am now polishing the patch with the help of my
   mentors and will soon send it to the mailing list. The seg fault occurred
   because I was deleting the refs in the for_each_ref_in() iteration. On
   sending the RFC[2], Michael Haggerty pointed out the fact that deleting refs
   causes some malfunction with the ref cache and thus triggering the seg
   fault.

 * I also converted bisect_write() function and currently I am polishing it
   with the help of my mentors and will send it to the mailing list. You can
   find the whole branch here[3].

 * As a preparatory patch for bisect_write() I also introduced a function
   file_size() which will get the file size without actually opening the
   file.

 * I also converted is_expected_rev() and check_expected_revs() and also fixed
   the segmentation fault. I am now polishing the patch with the help of my
   mentors and will soon send it to the mailing list. You can find the branch
   here[4].

 * My v2[5] on a cleanup patch to use the function macro GIT_PATH_FUNC is
   yet to receive comments.

 * I have also converted bisect_head()[6] but that would be sent to the mailing
   list along with bisect_state().

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

 * Convert the function bisect_write(). I plan to convert this function and
   add it as a subcommand.

 * Convert get_terms() and add the variables TERM_GOOD and TERM_BAD in a struct
   in the global state.

 * Convert bisect_voc()

 * Convert bisect_next_check()
