Understanding GitLab and Branching
What is GitLab?
GitLab is a centralized platform for storing and organizing code, providing access to the latest version for all team members. It simplifies collaboration by allowing multiple team members to work on the same project simultaneously. With its version control capabilities, GitLab records a new version every time changes are made, preserving the entire project history. This enables easy tracking of changes and reverting to previous versions when needed.
GitLab offers the following benefits:
- Centralized platform for code storage and organization
- Simultaneous collaboration
- Version control with complete project history
Tip: Use Git commands like
git clone
andgit add
to efficiently manage your code and collaborate with others.
Why Branching is Important in GitLab
Branching is a fundamental concept in GitLab that allows developers to work on different features or bug fixes simultaneously without interfering with each other’s work. It provides a way to isolate changes and experiment with new ideas without affecting the main codebase. By creating branches, developers can work independently and merge their changes back into the main branch when they are ready. This promotes collaboration, flexibility, and efficient development workflows.
In GitLab, branching is essential for:
- Parallel Development: Multiple developers can work on different branches simultaneously, speeding up the development process.
- Feature Isolation: Branches allow developers to isolate new features or bug fixes, making it easier to test and review changes before merging them into the main codebase.
- Version Control: Branches preserve the entire history of the project, allowing developers to track changes, revert to previous versions, and maintain a clean and organized codebase.
Tip: When creating branches in GitLab, it’s recommended to follow a naming convention that clearly identifies the purpose of the branch and its associated task or feature.
Types of Branches in GitLab
In GitLab, there are several types of branches that serve different purposes. The main types include:
-
Master Branch: This is the default branch in GitLab and is considered the main branch of the project. It contains the stable and production-ready code.
-
Feature Branch: Feature branches are created to develop new features or make changes to existing ones. They are typically short-lived and are merged back into the master branch once the feature is complete.
-
Release Branch: Release branches are used to prepare the code for a new release. They are created from the master branch and undergo testing and bug fixing before being merged into the master branch.
-
Hotfix Branch: Hotfix branches are created to quickly fix critical issues in the production code. They are created from the master branch and are merged back into both the master branch and any active release branches.
These different types of branches allow for a structured and organized development process in GitLab.

Creating and Managing Epic Branches
Creating a New Branch
To create a new branch in GitLab, follow these steps:
- Navigate to your project repository.
- Click on the "Branches" tab.
- In the "Branch name" field, enter a unique name for your branch.
- Optionally, you can choose to create the branch from an existing branch or commit.
- Click the "Create branch" button to create the new branch.
Once the branch is created, you can start working on it by making changes, committing them, and pushing the branch to the remote repository. Remember to regularly pull changes from the main branch to keep your branch up to date.
Naming Conventions for Epic Branches
When it comes to naming conventions for epic branches in GitLab, it’s important to keep them clear and descriptive. A good practice is to use a combination of the feature or task being worked on, along with the epic name or identifier. This helps to provide context and make it easier for team members to understand the purpose of the branch. For example, if you’re working on a feature called ‘user authentication’ within the ‘login’ epic, a suitable branch name could be ‘feature/user-authentication-login’. By following a consistent naming convention, it becomes easier to navigate and manage branches, especially when dealing with multiple epics and features. Remember, clarity and consistency are key to effective branch management.
Pushing and Pulling Changes
After making changes to your branch, you’ll need to push those changes to the remote repository. This allows others to see and review your work. To push your changes, use the command git push origin branch-name
. If you encounter any conflicts during the push, you’ll need to resolve them before proceeding.
Pulling changes from the remote repository is important to keep your local branch up to date with the latest changes made by others. Use the command git pull origin branch-name
to pull the latest changes. It’s a good practice to pull before starting any new work to avoid conflicts and ensure you’re working with the most recent code.
Remember, pushing and pulling changes are essential for effective collaboration and keeping your branch in sync with the remote repository.
Collaborating on Epic Branches
Adding Collaborators to a Branch
To add a collaborator to your branch, follow these steps:
- Enter the username or email of the person you want to invite as a collaborator.
- Choose the appropriate access level for the collaborator (Read, write, or admin).
- Click ‘Add collaborator’ to send the invitation.
Upon receiving the invitation, the collaborator can accept it and start contributing to the project.
Remember to grant the appropriate access level to ensure smooth collaboration and maintain security.
If you need to remove a collaborator, navigate to the ‘Settings’ tab in your repository on GitLab and click on ‘Collaborators’ in the left-hand sidebar. From there, you can remove a collaborator by clicking on the ‘Remove’ button next to their name.
Keep in mind that you can collaborate with any GitLab user, even if they are not part of your organization. Just add them as a collaborator and grant them the necessary access level.
Resolving Merge Conflicts
When multiple collaborators make changes to the same file simultaneously, it can result in merge conflicts. A merge conflict occurs when Git is unable to automatically combine the changes made by different collaborators. To resolve merge conflicts, follow these steps:
- Identify the conflicting sections of code in the file.
- Manually edit the file to incorporate the desired changes from both collaborators.
- Save the file and commit the changes using the git commit command.
- Finally, use the git push command to upload the resolved conflicts to GitHub.
It is important to communicate with your collaborators to avoid working on the same sections of code simultaneously and minimize the occurrence of merge conflicts.
Reviewing and Approving Changes
Reviewing and approving changes is a crucial step in the collaborative development process. It ensures that code modifications meet the project’s standards and align with the overall goals. Here are some best practices to follow when reviewing and approving changes:
- Thoroughly examine the code: Take the time to carefully review the changes made, ensuring they are correct, efficient, and adhere to the project’s coding conventions.
- Test the changes: Before approving the modifications, test them in a controlled environment to verify their functionality and compatibility with the existing codebase.
- Provide constructive feedback: If you identify areas for improvement or have suggestions, communicate them clearly and respectfully to the developer. This helps foster a collaborative and growth-oriented environment.
- Ensure documentation is updated: Check that any relevant documentation, such as README files or user guides, is updated to reflect the changes made.
Remember, the goal of reviewing and approving changes is to maintain code quality, promote collaboration, and ensure the project’s success.

Troubleshooting Common Issues
Branch Syncing Problems
Branch syncing problems can occur when Git is unable to automatically combine the changes made by different collaborators. To resolve merge conflicts, follow these steps:
- Identify the conflicting sections of code in the file.
- Manually edit the file to incorporate the desired changes from both collaborators.
- Save the file and commit the changes using the git commit command.
- Finally, use the git push command to upload the resolved conflicts to GitHub.
Reverting Changes in a Branch
Reverting changes in a branch allows you to undo a commit and revert your code back to a previous state. GitLab implements Git’s powerful feature to revert any commit with introducing a Revert button in Merge Requests and commit details. This makes it easy to undo changes without affecting the commit history. To revert a commit, simply click on the Revert button and GitLab will create a new commit that undoes the changes made in the original commit. It’s important to note that reverting a commit does not delete the original commit, but rather creates a new commit that undoes the changes. This allows you to easily track and manage your code changes. If you need to revert multiple commits, you can use the git revert command in the command line. This command allows you to specify the commit or range of commits that you want to revert. By using the revert feature in GitLab, you can easily undo changes and keep your codebase clean and organized.
Recovering Lost Branches
Losing a branch can be a frustrating experience, but fear not! GitLab provides several methods to recover lost branches and restore your work. Here are some steps you can take:
- Check the GitLab repository’s commit history to see if the branch was accidentally deleted or merged into another branch.
- If the branch was deleted, you can use the GitLab UI or command line to restore it from the repository’s trash or the GitLab server’s recycle bin.
- If the branch was merged into another branch, you can use GitLab’s branch comparison feature to identify the commit where the merge occurred and then create a new branch from that commit.
Remember to regularly backup your branches and repositories to prevent data loss. Additionally, consider using GitLab’s version control features, such as tags and milestones, to keep track of important points in your project’s history.
Pro Tip: If you frequently work on critical branches, consider enabling GitLab’s protected branches feature to prevent accidental deletion or force pushes.
