How to Revert Multiple Commits in GitLab

Working with GitLab involves frequent commits and pushes. Sometimes, you might find yourself needing to undo a series of changes, perhaps due to a bug, accidental changes, or a change in direction. GitLab provides a robust way to manage your commits, and reverting multiple commits is a common task for developers.

What is Commit Revert?

Before diving into reverting multiple commits, let's understand what a revert actually is. A revert is a Git operation that creates a new commit to undo the changes introduced by a previous commit. It's like creating a 'reverse' of the original commit, effectively undoing its impact.

Understanding the Need for Revert

You might need to revert multiple commits for various reasons:

Mistakes: You might have accidentally introduced bugs or unwanted changes in a series of commits.
Code Refactoring: You might have changed the code significantly, and you realize the new direction is not ideal.
Collaboration: You might be working on a branch with others, and you want to undo changes that were introduced by someone else.

Reverting Multiple Commits in GitLab

Here's how you can revert multiple commits in GitLab:

1. Identify the Commits:

First, you need to identify the commit IDs you want to revert. You can do this using the git log command. This command displays a chronological history of your commits.
Look for the SHA (commit hash) of the commits you want to revert.

2. Revert Each Commit Individually:

You can use the git revert <commit_id> command to revert each commit individually.
For example, to revert a commit with the hash abcdef12, you'd run:
```
git revert abcdef12
```

3. Commit the Reversions:

After reverting each commit, you'll need to commit the reverts to your local repository using git commit -m "Revert commit <commit_id>". Make sure to provide a clear and concise commit message.

4. Push to GitLab:

Finally, push the reverted commits to your GitLab repository using the git push command.

Important Considerations:

Branching: Ensure you are on the correct branch before proceeding with the reverts.
Conflicts: If the commits you are reverting have already been merged into other branches, you might encounter conflicts when pushing your reverts. Resolve these conflicts carefully.
History: The revert operation will create new commits, which will be visible in your commit history.
Collaborators: Communicate with collaborators to let them know about the reverts you are making, especially if you are reverting changes made by others.

Tips and Tricks:

Use git reflog: If you can't recall the exact commit IDs, git reflog can help you find them. It shows a log of your local repository's actions.
Interactive Rebase (Advanced): For a more powerful approach, use git rebase -i. This interactive rebase allows you to edit, squash, or revert multiple commits together. However, use this with caution, as it can rewrite your Git history.

Example:

Imagine you have three commits you want to revert:

Commit A (abcdef12) 
Commit B (98765432) 
Commit C (12345678)

You would run the following commands:

git revert abcdef12
git commit -m "Revert commit abcdef12"
git revert 98765432
git commit -m "Revert commit 98765432"
git revert 12345678
git commit -m "Revert commit 12345678"
git push

Conclusion:

Reverting multiple commits in GitLab is a powerful technique that enables you to undo changes effectively. By following these steps, you can revert individual commits, ensuring a clean and accurate history of your project. Remember to proceed with caution and communicate with collaborators to avoid potential issues.
