When To Use git pull --rebase?
Last Updated :
08 Aug, 2024
One of the common operations in Git is git pull, which fetches updates from a remote repository and integrates them into your local branch. By default, git pull performs a merge, but there is an alternative: git pull --rebase. In this article, we'll explore when and why you should use git pull --rebase instead of the default merge option.
When to Use git pull --rebase?
Using git pull --rebase can be beneficial in several scenarios. Here are some common situations where it is advantageous:
1. Keeping a Clean Commit History
When working on a shared codebase, multiple developers might be pushing changes to the same branch. Using git pull --rebase helps maintain a clean and linear commit history, making it easier to understand the sequence of changes.
Example:
- You and your teammate are working on the feature branch.
- Your teammate pushes changes to the remote feature branch.
- You have local commits that are not yet pushed.
In this case, using git pull --rebase will reapply your commits on top of the changes your teammate pushed, resulting in a linear history without unnecessary merge commits.
2. Avoiding Merge Conflicts
Rebasing helps minimize merge conflicts by reapplying your changes on top of the latest changes from the remote branch. This can be particularly useful when you frequently pull updates from a shared branch.
Example:
- You have made local changes to a file that has also been modified by your teammate and pushed to the remote branch.
- Performing git pull --rebase will first apply the remote changes and then reapply your local changes on top of them, reducing the chances of conflicts.
3. Integrating Changes from Long-Running Feature Branches
When working on long-running feature branches, the main branch (e.g., main or master) may receive updates from other developers. Regularly rebasing your feature branch on the main branch ensures that your changes are always built on top of the latest code, reducing the risk of conflicts when you finally merge your feature branch.
Example:
- You are working on a feature branch feature-xyz for an extended period.
- The main branch receives multiple updates during this time.
- Periodically performing git pull --rebase on feature-xyz keeps it up-to-date with main, simplifying the final merge process.
How To Use git pull --rebase:
Using this technique, your local commits are rebased on top of the changes that have been obtained from the remote repository. This eliminates pointless merging commits, resulting in a more tidy and linear history.
Step 1: Ensure Your Branch is Up-to-Date
Before performing a rebase, it's good practice to ensure your branch is up-to-date with the latest changes from the remote repository.
git fetch origin
Step 2: Execute git pull --rebase
Perform the rebase operation to integrate the remote changes into your local branch.
git pull --rebase origin main
Here, origin is the name of the remote repository, and main is the branch you want to pull changes from. Adjust these values based on your repository's configuration.
Step 3: Resolve Any Conflicts
During the rebase process, you might encounter conflicts. Git will pause the rebase and prompt you to resolve them. Resolve conflicts using your preferred method (e.g., manually editing files or using a merge tool).
Step 4: Continue the Rebase
Once conflicts are resolved, continue the rebase process.
git rebase --continue
Repeat steps 3 and 4 until the rebase is complete.
Step 5: Verify Your Changes
After the rebase is complete, it's a good idea to verify that your changes are as expected.
git log --oneline
Step 6: Push Your Changes
Finally, push your rebased branch to the remote repository. This step is necessary to update the remote branch with your rebased commits.
git push --force-with-lease origin main
