[GSOC Update] Week 2

================================= 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 having a segmentation fault which is yet
   not fixed by me. I will try this for one more day and then send it to the
   list for RFC.

 * I also converted is_expected_rev() and check_expected_revs() which also has
   segmentation fault.

 * I also converted bisect_head() function. I changed the semantics a little
   bit. Previously the shell function used to echo the string, now it returns
   the value to the caller.

 * I investigated why test no. 43 and 44 are failing with t6030 with `|| exit`
   in the previous version of the patch but it didn't in the newer one. This
   is because the location of .git was hardcoded and thus it created problems
   with bare repositories.

 * I also sent a cleanup patch for using the marco GIT_PATH_FUNC to create a
   function instead of using git_path() because of the benefits described
   in the commit message of that change.

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

 * Finish bisect_clean_state() conversion.

 * Finish is_expected_rev() and check_expected_revs() conversion.

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

 * Convert bisect_reset() 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.
