Git Bisect

Binary search through your git log to find where you hecked up and introduced a bug.

This command saved my life. I was trying to debug a really silly error that I couldn’t debug with error messages because the issue happened because a method was added to a core class and the stacktrace was not helpful. git bisect was the ONLY thing that worked.

Video I watched:

Notes

git bisect start
git bisect bad          # marks current commit doesn't work
git bisect good d0bf3f6 # specify latest commit that *does* work

# for each commit given, mark bad or good with
git bisect bad
git bisect good
# when done,
git bisect reset
