Understanding GitLab PR

How to Create PR in GitLab

What is a GitLab PR?

A GitLab PR, short for Pull Request, is a way to propose changes to a GitLab repository. It allows developers to submit their code modifications for review and eventual integration into the main codebase. With a PR, you can share your work with other team members, gather feedback, and collaborate on improvements. It serves as a communication tool, enabling discussions and discussions around code changes. PRs are an essential part of the GitLab workflow, facilitating a structured and organized approach to code collaboration.

Why are GitLab PRs important?

GitLab PRs are an essential part of the development workflow, serving as a mechanism for collaboration and code review. They allow developers to propose changes to a project and have those changes reviewed and approved by their peers before merging them into the main codebase. This process ensures that code quality is maintained, potential bugs are caught early, and knowledge sharing and learning opportunities are created within the team. GitLab PRs also promote transparency and accountability, as all changes and discussions are documented and can be easily traced back to their origin.

How do GitLab PRs work?

GitLab PRs provide a way for developers to propose changes to a repository and initiate a code review process before merging those changes. When you create a PR, you are essentially notifying others about the modifications you want to make to the original repository. The maintainers of the repository can then review your changes, discuss them, and decide whether to integrate them into the base branch. This collaborative workflow promotes open communication and allows team members to analyze code changes and provide recommendations. To create a PR in GitLab, you can go to the ‘Create Pull Request’ option in the GitLab interface. The PR can be based on a new branch that you create, which contains the changes you want to propose. Once the PR is created, it can be reviewed, commented on, and eventually merged into the base branch.

Setting up your GitLab repository

To set up your GitLab repository, follow these steps:

  1. Navigate to the desired directory where you want to create your repository.
  2. Initialize a new Git repository by running the command git init.
  3. Create a file called using your preferred text editor.
  4. Stage the added file by running the command git add
  5. Commit your changes by running the command git commit -m 'Initial commit'.
  6. Finally, push your changes to your GitLab repository by running the command git push origin master.

Remember to replace origin with the name of your remote repository and master with the name of your branch if applicable.

Creating a new branch

To create a new branch in GitLab, follow these steps:

  1. Go to your GitLab repository and navigate to the branch dropdown menu.
  2. Click on ‘New branch’ to create a new branch.
  3. Enter a name for your new branch, preferably related to the feature or task you are working on.
  4. Optionally, you can choose to create the new branch from an existing branch or from the latest commit in the repository.
  5. Click on ‘Create branch’ to create the new branch.

Creating a new branch allows you to work on your changes separately from the main branch. This way, you can make and commit your changes without affecting the main branch. It also makes it easier to collaborate with other developers, as they can review and provide feedback on your changes before merging them into the main branch.

Making changes to your code

After setting up your GitLab repository and creating a new branch, it’s time to start making changes to your code. This could include adding new files, modifying existing files, or deleting files. Once you have made the changes, you should commit them to the branch. Once the changes have been committed, you should create a merge request. This will allow other developers to review the changes and provide feedback. Once the merge request has been approved, you can merge the changes into the master branch. Finally, you should deploy the changes to the production environment. This will ensure that the new feature is available to users.

Committing and pushing your changes

Once you have made the necessary changes to your code, it’s time to commit and push them to your branch. This step is crucial as it saves your changes and makes them available for review. Here’s how you can commit and push your changes:

  1. Review your changes in the Files tab. Double-click on any file to open the Diff view and ensure everything looks good.
  2. Craft a meaningful commit message that summarizes the changes you’ve made. A clear and descriptive commit message helps in understanding the history of your repository.
  3. Click on the ‘Commit & Push’ button to save your changes and push them to your branch.

Remember, committing and pushing your changes is an important step in the GitLab PR workflow. It allows other developers to review your changes and provide feedback. So make sure to double-check your changes and write a concise commit message before pushing.

Creating a new PR

To create a new pull request in GitLab, follow these steps:

  1. Make sure you have set up your GitLab repository and have created a new branch for your changes.
  2. Make the necessary changes to your code in the branch.
  3. Commit and push your changes to the branch.
  4. Once your changes are pushed, navigate to the repository in GitLab and click on the ‘New merge request’ button.
  5. Fill in the necessary details for the merge request, such as the source and target branches.
  6. Optionally, you can add reviewers, assign the pull request to someone, or add labels.
  7. Click on the ‘Create merge request’ button to create the pull request.

Remember to save your pull request as a draft if you’re not yet ready to push it. You can always come back to it later and make further changes.

Reviewing a GitLab PR

Understanding the PR review process

After posting a comment or a suggestion, you need to submit a review. Click Submit on the editor toolbar. Select one of the possible outcomes: Approve – to approve merging changes. Request changes – to submit feedback, a pull request author must apply before merging. Comment – to submit a comment without an approval.

Providing constructive feedback

When providing feedback on a GitLab PR, it’s important to be constructive and helpful. Focus on the specific areas that need improvement and provide suggestions for how to address them. Avoid personal attacks or negative language, as this can hinder collaboration and discourage the PR author.

Consider using a bulleted list to outline your feedback points, making it easier for the author to understand and address each point individually. Additionally, you can use bold formatting to highlight important keywords or concepts.

Remember, the goal is to help the PR author improve their code and contribute to the project’s success. By providing constructive feedback, you contribute to a positive and productive review process.

Approving or requesting changes

When reviewing a GitLab PR, you have the option to either approve the changes or request further modifications. To approve the changes, simply click on the ‘Approve’ button. If you believe that changes are necessary, you can request them by leaving comments or suggestions. Remember to submit your review after providing feedback. Here are the possible outcomes:

  • Approve: Use this option to approve merging the changes.
  • Request changes: Select this option to submit feedback and ask the pull request author to make the necessary modifications.
  • Comment: Use this option to submit a comment without providing an approval.

If you change your mind after approving or requesting changes, you can revoke your approval or modify your feedback. Once the work with the merge request is complete, you can merge or close it in the same merge request details tab.

Resolving conflicts

Resolving conflicts is a common part of the GitLab PR workflow. When multiple branches have made conflicting changes to the same file, GitLab will automatically detect the conflicts and mark them for resolution. To resolve conflicts in a GitLab PR, follow these steps:

  1. Checkout the branch locally and pull the latest changes.
  2. Open the conflicting file(s) in your preferred code editor.
  3. Locate the conflicting sections and make the necessary changes to resolve the conflicts.
  4. Save the file(s) and commit the changes.
  5. Push the branch with the resolved conflicts.

Remember to communicate with your team members if you encounter any difficulties or need clarification on how to resolve specific conflicts.

Merging the PR

Once you have reviewed and resolved any conflicts in the PR, it’s time to merge it into the base branch. To merge the PR, follow these steps:

  1. Click the Merge button on the PR page.
  2. Select the branch you want to merge the changes into.
  3. Optionally, add a comment or description for the merge.
  4. Click Merge to complete the merge.

Remember to only merge the PR when you are confident that the changes are ready to be integrated into the base branch. It’s important to ensure that the code is thoroughly reviewed and tested before merging.

Tip: Before merging, double-check that all discussions and feedback have been addressed. This helps maintain the quality and integrity of the codebase.

Once the PR is merged, the changes will be applied to the base branch and the PR will be closed. Congratulations on successfully merging your PR!

Best Practices for GitLab PRs

How to Create PR in GitLab

Keeping PRs small and focused

When creating a pull request, it’s important to keep it small and focused. This ensures that the changes are easy to review and understand. Here are some tips to achieve this:

  • Break down large changes into smaller, logical chunks. This allows for better comprehension and reduces the risk of introducing errors.
  • Focus on addressing a specific issue or implementing a single feature. This helps maintain clarity and prevents the PR from becoming overwhelming.
  • Avoid including unrelated changes or refactoring in the same PR. Keep each PR dedicated to a specific purpose.

Remember, the goal is to make the review process efficient and effective. By keeping PRs small and focused, you increase the chances of receiving timely feedback and getting your changes merged quickly.

Writing clear and descriptive PR titles

When creating a GitLab PR, it is crucial to write clear and descriptive titles that accurately convey the purpose of the PR. A well-crafted title helps reviewers and team members understand the intent of the changes and facilitates efficient collaboration.

To make your PR titles stand out, consider the following tips:

  • Format at most one important keyword in bold and use italics for subtle emphasis where needed.
  • Keep the title concise and focused, avoiding unnecessary details.
  • Use a bulleted or numbered list for less structured content, like steps, qualitative points, or a series of related items.

Remember, the goal of a PR title is to provide a quick overview of the changes and grab the attention of reviewers. By following these best practices, you can ensure that your PR titles are informative and help streamline the review process.

Tip: When using GitLab Ultimate, take advantage of the advanced features and integrations available to enhance your PR workflow.

Including relevant context and documentation

When creating a GitLab PR, it’s important to provide relevant context and documentation to help reviewers understand the changes you’ve made. This can include explaining the problem you’re trying to solve, providing background information on the code you’ve modified, and linking to any relevant documentation or resources. By including this information, you can ensure that reviewers have all the necessary information to provide valuable feedback and make informed decisions.

Collaborating with team members

Collaboration is a key aspect of working with GitLab PRs. It allows team members to review and provide feedback on each other’s code, ensuring that the final product meets the highest standards. Here are some best practices for collaborating effectively:

  • Open Communication: Maintain open and clear communication channels with your team members. Use tools like GitLab’s commenting feature to discuss code changes, ask questions, and provide suggestions.

  • Assigning Reviewers: Assign specific team members as reviewers for your PRs. This ensures that the right people are involved in the review process and can provide valuable insights.

  • Reviewing Others’ PRs: Take the time to review and provide feedback on your team members’ PRs. This not only helps improve the quality of the code but also fosters a collaborative and supportive environment.

  • Resolving Conflicts: In case of conflicts between different PRs, work together with your team members to resolve them. Use GitLab’s merge conflict resolution tools to streamline the process.

  • Merging the PR: Once the review process is complete and all feedback has been addressed, the PR can be merged into the main branch. Make sure to follow your team’s merge process and guidelines to ensure a smooth integration of the code.

Closing and cleaning up PRs

Once you have completed the review process and all necessary changes have been made, it’s time to close and clean up your pull request. Here are some best practices to follow:

  • Resolve any conflicts: If there are any conflicts between your branch and the base branch, make sure to resolve them before closing the PR.
  • Close the PR: Once your changes have been merged or rejected, close the pull request to indicate that it is no longer active.
  • Delete the branch: After closing the PR, delete the branch associated with it to keep your repository clean and organized.

Remember, closing and cleaning up PRs is an important step in the GitLab workflow to ensure that your changes are properly integrated and your repository remains tidy.
