Git Undo Commit Before Push Made Easy
Blog post from Mergify
The text provides a comprehensive guide on handling mistakes in Git commits before pushing them to a remote repository. It emphasizes the safety of local edits, explaining that until changes are pushed, they remain as drafts on a developer's machine, allowing for corrections without affecting teammates. Key commands discussed include `git commit --amend` for minor tweaks to the most recent commit and `git reset` in its various forms—soft, mixed, and hard—for more substantial rewrites of local history. The document advises caution with these commands, particularly `git reset --hard`, due to its potential to permanently erase changes. For changes already pushed to a shared branch, it recommends using `git revert`, which creates a new commit to counteract the unwanted changes, preserving the project’s history intact. It also underscores the importance of maintaining a clean Git history through small, atomic commits and highlights the necessity of understanding team conventions to avoid collaboration issues. Additionally, the text differentiates between `git reset` and `git revert`, outlining the contexts in which each should be used, and discusses the careful use of force-pushing with `git push --force-with-lease` as a safer option for aligning local and remote branches.
