Comprehensive Git Best Practices and Common Pitfalls

1. What is Git – Git is a distributed version‑control system that tracks directory changes, stores full history, and operates without a central server, enabling each clone to be a complete repository.

2. What is not Git – Services like GitHub/GitLab, forks, merge/pull requests are not part of Git itself; they are platform features built on top of Git.

3. Choose the right tool – A good GUI such as TortoiseGit (Windows) or similar tools can greatly improve efficiency and reduce errors compared to command‑line only.

4. Work locally – Perform all operations on the local repository; remote actions are optional and often slower.

5. Branch strategy – Use a clear hierarchy: main (stable), develop (integration), optional team‑specific develop branches, short‑lived feature branches, and release branches prefixed with release/ . Merge or rebase according to branch lifespan.

6. Merge vs. Rebase – Merge creates a merge commit preserving history; rebase rewrites commits onto the target tip. Combine with optional squash for clean history. Amend can replace the previous commit during development.

7. Resolve merge conflicts – Rebase the feature branch onto the target, resolve conflicts, then force‑push. Avoid creating new merge‑requests after conflict resolution.

8. Use fetch instead of pull – git fetch retrieves updates without automatic merging; you can then rebase manually, avoiding unnecessary merge commits.

9. Small, atomic commits – Keep each commit focused on a single change (atomic). Split large or incomplete commits using branch splits, amend, or interactive rebase.

10. LFS tips – Enable Git LFS for large binary files. Common commands: git lfs fetch --all Add large‑file patterns to .gitattributes and renormalize existing files: git add --renormalize . Avoid over‑using LFS (treating every file as large) and be aware of its lock semantics.

11. Git’s drawbacks – Lack of built‑in branch permission management, performance issues with very large monolithic repositories, and limited support for sparse checkouts in some services. Tools like Google’s repo , Microsoft’s VFSForGit/Scalar, and Git protocol v2 aim to mitigate these issues.

12. Summary – Git offers many paths to achieve the same goal; understanding its logic and applying the best‑practice guidelines above helps developers maintain efficient, reliable version control while avoiding common pitfalls.
