Git Version Control Best Practices
Welcome to the James Anthony Consulting (JAC) blog! As a firm that thrives on innovation and collaboration, we understand the importance of efficient software development practices. In this post, we'll dive into the world of Git – a cornerstone tool for our development teams – and discuss the best practices and etiquette that keep our projects running smoothly.
What is Git?
Before we delve into the nitty-gritty, let's have a quick recap. Git is a distributed version control system, essential for tracking changes in source code during software development. It's designed for coordinating work among programmers, but it can be used to track changes in any set of files.
1. Commit Messages: Clear and Concise
The Importance of Meaningful Messages: Write clear, concise commit messages that explain the 'why' behind the change, not just the 'what'.
Conventions: Follow a standard format for commit messages (e.g., starting with a capital letter, no period at the end).
Tagging: Tag commits which contain code which has been released, including the environment descriptor and version number.
Timing: Commit and push at least once per day. If your commit contains a breaking change or a partially-implemented feature, place it in a branch.
2. Branching Strategy: Stay Organised
Branch Naming Conventions: Use descriptive branch names that reflect the feature or fix they're addressing.
Short-lived Branches: Aim to keep branches short-lived to reduce merge conflicts and streamline the development process.
Mirror Environments: Have one branch for each hosting environment.
Keep Up To Date: Be sure to pull master each morning, and merge it into your created branches. If you created the branch, you own the branch!
3. Pull Requests and Code Reviews: Collaborate Effectively
Descriptive Pull Requests: When creating a pull request, provide context and link to relevant tickets or discussions.
Peer Reviews: Encourage thorough code reviews to maintain code quality and share knowledge across the team.
4. Handling Merge Conflicts: With Care
Prevention: Regularly pull changes from the main branch to minimise conflicts.
Resolution: When conflicts arise, resolve them carefully, ensuring you understand the changes from all sides.
5. Git History: Keep It Clean
Avoiding Rewrites: Refrain from rewriting published history unless absolutely necessary.
Squash and Merge Appropriately: Use squash merging for feature branches to keep the main branch history clean and understandable.
6. Continuous Integration: Streamline Development
Automate Testing: Utilise CI tools to automatically run tests on new commits, ensuring that changes don't break existing functionality.
Immediate Fixes: Address any integration issues as soon as they're discovered.
Conclusion
Adhering to these Git best practices not only enhances individual productivity but also fosters a collaborative environment where ideas can flourish and innovation is the norm. Remember, effective use of Git goes beyond just managing code – it's about managing changes in a way that benefits the entire team.
