but the output is not not showing clearly which commit to develop has broken it.

Answer 1

Two points to consider:

• Git does not track file renames: it does not record them to the commit history, so a rename appears in a commit as a removal of the file with the old name and addition of the file with the new name.

  So if your file got renamed, you have to exercise the Git's ability to detect renames/copies at the history traversal (that's what git log does in the first place). Look at the -M and -C command-line options of git log for more info.

• There exists lesser-known features of git log which are of immence power: the -S , -G and -L options. (Also see the accompanying --pickaxe-all and --pickaxe-regex options).

  These features allow for searching the history for the appearances or disappearances of particular bits of code, and more.
