Finding which commit introduced a bug becomes increasingly difficult as your commit history grows, especially when the bug was introduced weeks or months ago. With over 25 years of software development experience and as the creator of CoreUI, I’ve tracked down countless elusive bugs in large codebases. Git bisect uses binary search to efficiently identify the problematic commit by testing commits between a known good state and a known bad state. This approach can find the bug-introducing commit in just a few steps, even with hundreds of commits in between.
