In this lesson, we’ll explore the intricacies of Git merging and conflict resolution, using the development of a collaborative open-source project as our core example. Imagine multiple contributors working on different features simultaneously. Sarah is implementing a new search functionality, while Michael is optimizing the database queries. When it’s time to integrate their changes, Git’s merging capabilities shine.
Sarah creates a new branch, `feature-search`, and starts coding. Meanwhile, Michael works on the `optimize-db` branch. Both regularly commit their progress. Once their features are complete, they need to merge their branches back into the main branch.
Sarah initiates a pull request, and Git detects no conflicts. Her changes are seamlessly merged. However, when Michael tries to merge his branch, Git alerts him to conflicts in `database.js`. Git marks the conflicting lines, and Michael must manually resolve them.
Michael opens the file, examines the conflicts, and decides which changes to keep. He removes the conflict markers and commits the resolved version. With conflicts settled, the merge is complete.
Git’s ability to handle merges and conflicts enables smooth collaboration. By creating separate branches, developers can work independently and later integrate their changes. When conflicts arise, Git provides tools to identify and resolve them, ensuring a cohesive final version of the codebase.
