git bisect

git bisect lets you walk forward and backwards in time, automatically checking out branches, and let you isolate something that broke the build. You bisect, run tests, and then say bisect good or bad. git automatically increments binary forward / backward. Then when you find offending commit you compare with head for diff.

Clean master

git bisect start
git bisect bad
git log (pick a suspect commit i.e e576341668478ec71d5e642bb63d9ada57785878)
git checkout e576341668478ec71d5e642bb63d9ada57785878 // check it out
git bisect good         // keep bisecting until you come to the bad commit
git bisect good
git bisect bad         // when you find the bad commit, mark it bad
git bisect good        // then bisect again to get the previous good commit

Note the output. It tells you where the first bad commit is. Note it and check it out. You are now on the bad commit. Compare this commit with the previous to note the differences.

git checkout 39ff0ffe5114a6a9011dd28ebe3ac3bdc92163e0
git diff HEAD~1


You can copy this output into the paste board to save. Then checkout the previous version that works (a good one) and manual copy in the changes one at a time until you find the source of the break.
git diff HEAD~1 | pbcopy
git checkout HEAD~1

To stop:
git bisect reset
