Efficiently managing merge requests not only speeds up the development process but also ensures that the codebase remains clean and maintainable.

Advanced Merge Request Features

Draft Merge Requests

Draft Merge Requests are perfect for when you’re not quite ready for a full review but want to share your progress. They allow you to gather early feedback and make adjustments before the final submission. This feature is invaluable for iterative development and helps ensure that your code is on the right track from the start.

Confidential Merge Requests

When working on sensitive projects, Confidential Merge Requests keep your work under wraps. Only authorized team members can view and comment on these requests, ensuring that sensitive information remains secure. This is particularly useful for customer critical merge requests where privacy is paramount.

Merge Request Dependencies

Merge Request Dependencies let you define relationships between different merge requests. This is especially useful when you have multiple, interrelated changes that need to be merged in a specific order. By setting dependencies, you can avoid integration issues and ensure a smooth, orderly merge process.

Using Merge Request Dependencies can significantly reduce the risk of merge conflicts and streamline your workflow.

Automating Merge Requests

Automating merge requests in GitLab can save you a lot of time and effort. By setting up automated processes, you can ensure that your code is always up-to-date and that your team can focus on more important tasks. Let’s dive into how you can automate merge requests effectively.

Best Practices for Merge Requests

Writing Effective Commit Messages

A clear and concise commit message is crucial. It helps reviewers understand the changes quickly. Always start with a short summary of the changes, followed by a detailed description if necessary. This practice not only aids in code review but also in future code maintenance.

Squash and Merge

When a merge request has many commits, consider using the Squash and Merge feature. This combines all commits into one, making the commit history cleaner. It’s especially useful if the merge request has a messy commit history. Squashing commits can save time and avoid unnecessary back-and-forth with reviewers.

Cherry Picking Changes

Cherry picking allows you to select specific commits from one branch and apply them to another. This is useful when you need to apply a bug fix to multiple branches. It ensures that critical fixes are not missed in any branch.

Performing a self-review of your own merge request can help avoid unnecessary back-and-forth with reviewers. Include comments on lines where decisions or trade-offs were made.

Reviewing Merge Requests

Before submitting a merge request, perform a self-review. Follow the code review guidelines and include comments where necessary. This helps the reviewer understand the context and reduces the overall time-to-merge.

Assigning Reviewers

Identify reviewers who have the necessary understanding of the feature. Direct all related merge requests to these reviewers to maintain consistency. This practice is especially useful when you need multiple merge requests to deliver a feature.

Handling Merge Conflicts

Merge conflicts are inevitable. When they occur, resolve them promptly to keep the workflow smooth. Use GitLab’s conflict resolution tools to make this process easier.

Using the Web Editor

GitLab’s web editor is a powerful tool for making quick changes. Use it for minor edits and to resolve small merge conflicts. It saves time and keeps the development process agile.

Troubleshooting Merge Requests

Common Issues and Fixes

When working with merge requests, you might encounter a few common issues.
