Resolving Merge Conflicts in Git Through Manual Intervention

Merge conflicts arise in Git when different collaborators or different branches edit the same part of a file but in different ways, and Git finds it challenging to decide which set of changes to incorporate in the final codebase.

The correct resolution for these merge conflicts is not automated by Git itself, nor it is resolved by creating a new branch, deleting the conflicting files, or using a non-existent 'git conflict' command. Instead, the resolution involves manually editing the conflicting files and then committing the result.

The Steps to Resolve Merge Conflicts

Here is a step-by-step synopsis:

1. Identify the conflicted files: After a failed git merge, Git will output a list of files causing the conflict.

2. Navigate to the conflicted file(s) in your text editor and look for the conflict markers (=======, HEAD, and >>>>>>>) which indicate the HEAD (current branch) and comparing branch's respective changes.

3. Choose the code changes to keep by deleting the other set of changes along with the conflict markers.

4. Once you've successfully resolved the conflict in your file, save your file.

5. Follow this by staging your changes using git add <resolved-file>.

6. Finally, commit these changes using git commit.

Practical Example

Here is an example of a dummy merge conflict:

<<<<<<< HEAD
This is some content written on the current branch.
=======
This is some content written on the branch to be merged.
>>>>>>> new-branch

The lines between <<<<<<< HEAD and ======= display the changes in the current branch. The lines between ======= and >>>>>>> new-branch display the changes in the new-branch that is intended to be merged. A user has to carefully review the changes and decide which among them will remain in the final codebase.

Best Practices for Resolving Git Merge Conflicts

While the manual process is straightforward, it's essential to keep some practices in mind:

1. Communicate with your team: When working on a team project, ensure you communicate with the respective collaborators who have worked on the conflicting lines of code to avoid any functional mishaps.

2. Commit Often, Merge Less: Frequently committing your changes helps to reduce the complexity of resolving merge conflicts.

3. Use Merge Tools: Various merge tools can make the process of resolving merge conflicts much easier. Learn about git mergetool, a built-in interface in Git that helps manage merge conflicts.

In conclusion, while merge conflicts can seem daunting initially, resolving them is an integral aspect of collaborative coding projects. Understanding how to appropriately navigate and resolve these conflicts can streamline your development process, and keep your project moving along smoothly.
