Find the Exact Commit That Broke Production
Basic performance debugging fails when engineers manually test hundreds of commits to find where a regression was introduced. Line-by-line history checks waste hours and make performance troubleshooting frustratingly slow.
Never hunt for breaking changes by hand. Automate binary search across thousands of commits using git bisect run. Write a simple test script that exits 0 if fast and 1 if slow. Define your boundaries with git bisect good and git bisect bad , then execute git bisect run node test.js. Git automatically tests history midpoints, cuts the search space in half each round, and pinpoints the exact culprit in under ten steps before you run git bisect reset.
Automating regression checks turns needle-in-a-haystack debugging into a fast, deterministic script execution.
