--- name: managing-git description: Manages Git workflows including branching, commits, and pull requests. Use when working with Git, creating commits, opening PRs, managing branches, resolving conflicts, or when asked about version control best practices. --- # Managing Git ## Feature Development Workflow Copy this checklist and track progress: ``` Feature Development Progress: - [ ] Step 1: Create feature branch from main - [ ] Step 2: Make changes with atomic commits - [ ] Step 3: Rebase on latest main - [ ] Step 4: Push and create PR - [ ] Step 5: Address review feedback - [ ] Step 6: Merge after approval ``` ## Branching Strategies ### GitHub Flow (Recommended for most projects) ``` main ──●────●────●────●────●── (always deployable) \ / feature └──●──●──┘ ``` - `main` is always deployable - Feature branches from main - PR + review + merge - Deploy after merge ### Git Flow (For release-based projects) ``` main ──●─────────────●────── (releases only) \ / release └────●────┘ / develop ──●──●────●──●──●── \ / feature └──●┘ ``` ## Commit Conventions ### Conventional Commits Format ``` (): [optional body] [optional footer(s)] ``` ### Types | Type | Description | |------|-------------| | `feat` | New feature | | `fix` | Bug fix | | `docs` | Documentation only | | `style` | Formatting, no logic change | | `refactor` | Code change that neither fixes bug nor adds feature | | `perf` | Performance improvement | | `test` | Adding/updating tests | | `chore` | Build process, dependencies | | `ci` | CI configuration | ### Examples ```bash feat(auth): add OAuth2 login support Implements Google and GitHub OAuth providers. Closes #123 BREAKING CHANGE: Session tokens now expire after 24h ``` ```bash fix(api): handle null response from payment gateway Previously caused 500 error when gateway returned null. Now returns appropriate error message to user. ``` ## Branch Naming ``` /- # Examples feature/AUTH-123-oauth-login fix/BUG-456-null-pointer chore/TECH-789-upgrade-deps ``` ## Pull Request Workflow Copy this checklist when creating PRs: ``` PR Checklist: - [ ] Code follows project conventions - [ ] Tests added/updated for changes - [ ] All tests pass locally - [ ] No merge conflicts with main - [ ] Documentation updated if needed - [ ] No security vulnerabilities introduced - [ ] PR description explains the "why" ``` ### PR Template ```markdown ## Summary [Brief description of changes] ## Changes - [Change 1] - [Change 2] ## Testing - [ ] Unit tests added/updated - [ ] Manual testing performed - [ ] E2E tests pass ## Screenshots (if UI changes) [Before/After screenshots] ``` ### PR Size Guidelines | Size | Lines Changed | Review Guidance | |------|---------------|-----------------| | XS | < 50 | Quick review | | S | 50-200 | Standard review | | M | 200-500 | Thorough review | | L | 500+ | Split if possible | ## Common Git Commands ### Daily Workflow ```bash # Start new feature git checkout main git pull git checkout -b feature/TICKET-123-description # Commit changes git add -p # Stage interactively git commit -m "feat: description" # Keep up with main git fetch origin main git rebase origin/main # Push and create PR git push -u origin HEAD ``` ### Fixing Mistakes ```bash # Amend last commit (before push) git commit --amend # Undo last commit (keep changes) git reset --soft HEAD~1 # Undo last commit (discard changes) git reset --hard HEAD~1 # Revert a pushed commit git revert # Interactive rebase to clean up git rebase -i HEAD~3 ``` ### Advanced Operations ```bash # Cherry-pick specific commit git cherry-pick # Find which commit broke something git bisect start git bisect bad HEAD git bisect good # Stash with message git stash push -m "WIP: feature description" git stash list git stash pop ``` ## Commit Validation Before pushing, validate commits: ``` Commit Validation: - [ ] Each commit has a clear, descriptive message - [ ] Commit type matches the change (feat, fix, etc.) - [ ] No WIP or temporary commits - [ ] No secrets or credentials committed - [ ] Changes are atomic (one logical change per commit) ``` If validation fails, use `git rebase -i` to clean up commit history before pushing.
