When 47 Commits Stand Between You and Sanity
You run your test suite. 12 failures. The deploy worked fine last week. Somewhere in the last 47 commits, someone broke the authentication flow, and now you're staring at git log --oneline wondering if you should just git blame every file and start a fight.
There's a faster way. git bisect does binary search through your commit history. Instead of checking all 47 commits, you check 6. It's logarithmic ($\log_2(47) \approx 5.6$), and you don't need to understand the math to use it.
Here's the thing: most tutorials explain bisect like it's some advanced Git wizardry. It's not. It's five commands, and the workflow is more mechanical than clever. You tell Git which commit is broken, which one was fine, Git picks a middle commit, you test it, repeat. That's it.
The 5-Command Workflow
Start bisect, mark the bad commit (usually HEAD), mark a known-good commit, test the commit Git checks out, repeat until Git finds the culprit.
python
# 1. Start bisect
git bisect start
