How git merge requests restrict meta branches

In Git, merge request (Merge Request) is an extremely important function in collaborative development. Through merge requests, team members can easily merge their code contributions into the main branch of the project to ensure code consistency and stability. However, sometimes we need to limit the selection of source branches (also called meta branches) for merge requests to ensure the quality and safety of the code. This article will explain how to limit meta branches for Git merge requests.

1. Branch Protection

In code hosting platforms such as GitLab, we can use the "Branch Protection" function to limit the meta branches of Git merge requests. Branch protection is a setting that limits and protects branches. Through this function, we can prohibit operations such as Push and Merge Request on specified branches.

First, go into the project settings in GitLab and select the "Branch" tab. Here we can see a list of branches for all projects. Next, select the branch you want to restrict (usually the trunk branch) and click the "Protect Branch" button.

In the protected branch settings page, we can choose the operations to be prohibited according to our needs, such as prohibiting branch push, merge request, fusion request, deletion, etc. Most importantly, we can also limit the selection of meta branches. In the "The following branches cannot be selected as the source branch of the merge request" option, select the branch that needs to be restricted.

2. Code Review

In addition to branch protection, another way to limit Git merge requests to meta branches is through code review. Code review is a method of manually reviewing code to ensure code quality and security. During the code review process, reviewers can check the style, correctness, security, etc. of the code and discover and fix potential problems and vulnerabilities.

In Git, we can limit the meta branches of Git merge requests by setting reviewers and review rules. For example, we can require that each merge request must be approved by at least two reviewers, and must meet conditions such as code style specifications and unit test passing before it can be merged. In this way, the quality and security of the code can be ensured even without limiting the choice of meta branches.

3. Restrict merge permissions

In addition to the above two methods, you can also restrict the meta branch of Git merge requests by restricting merge permissions. In Git, we can set the permissions of each branch, for example, only allow some people to perform merge operations under certain conditions.

First, enter the branch settings page in Git, then select the branch that needs to be restricted, and set the permissions in the "Permissions" option. For example, we can set that only project administrators can merge merge requests for that branch, or only developers who meet certain conditions can perform merge operations.

Summary:

For meta branch restrictions on Git merge requests, we can use a variety of methods, such as branch protection, code review, limiting merge permissions, etc. These methods have their own advantages, disadvantages and applicable scenarios. We need to choose the appropriate method according to the specific situation to ensure the quality and security of the code.
