Managing Git

When to Load

• Trigger: Branching strategies, commit workflows, pull requests, merge conflicts, version control questions
• Skip: Tasks that do not involve git operations

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      └──●┘

PR Size Guidelines

Common Git Commands

Daily Workflow

# 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

# 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 <commit-hash>

# Interactive rebase to clean up
git rebase -i HEAD~3

Advanced Operations

# Cherry-pick specific commit
git cherry-pick <commit-hash>

# Find which commit broke something
git bisect start
git bisect bad HEAD
git bisect good <known-good-commit>

# 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.
