Git bisect is a powerful tool for efficiently finding the commit that introduced a regression (a bug that broke previously working functionality) in your codebase. It leverages binary search to quickly pinpoint the culprit commit by repeatedly checking out commits between a known "good" state (where the bug did not exist) and a known "bad" state (where the bug does exist).
Here's how to use git bisect to find the source of a regression:
Start the bisect process by running git bisect start.
Specify the "bad" commit where the regression exists by running git bisect bad [<bad_commit>]. If you don't provide a commit hash, it assumes the currently checked out commit is bad.
Specify the "good" commit where the regression did not exist by running git bisect good <good_commit>. Git will then check out a commit halfway between the good and bad commits.
Test the checked out commit to see if the regression is present. If it is, run git bisect bad. If not, run git bisect good.
Repeat step 4, testing each commit and marking it as good or bad, until git narrows down to the exact comm...
