How to prevent and solve the problem of GitLab accidentally deleting remote branches

As the number of programmers continues to grow, code management is becoming more and more important in the software development process. Git is one of the powerful tools for code management. It can not only manage local code, but also collaborate on remote code development. However, due to some factors, remote branches may be deleted accidentally. This article will introduce how to prevent and solve the problem of accidentally deleting remote branches in GitLab.

1. How to prevent GitLab from deleting remote branches

1. Before officially pushing to the remote, it is best to confirm locally.

When using Git for team collaboration, each developer needs to work on a local branch. When the local work is completed, the code needs to be pushed to GitLab for review and discussion by other developers. At this stage, it is recommended to complete code testing locally and run unit tests to ensure the correctness of the code.

Before pushing, use the git branch command to check whether all current local branches are in the latest status. After confirmation, you can use the git push command to push the remote code to GitLab.

2. Set up GitLab

In order to protect remote branches, you can also set it up in GitLab. Open the settings menu of GitLab, click "Protected Branch", and add the branch that needs to be protected to the list. In this way, when making a commit or merge request, GitLab will check whether you have permission to perform the operation.

3. Back up remote code

Backing up remote code is the third way to prevent accidental deletion. Whether you are an individual or a team, you should back up your GitLab code regularly. The backup operation is not difficult. You can create a new project on GitLab and use the git clone command to copy the local code into the project. Finally, push the project to GitLab to complete the backup.

2. How to solve the problem of GitLab deleting remote branches

Even if you do the above three points, you may still delete the remote branch accidentally. In this case, the following steps should be taken to restore the remote branch.

1. Find the deleted remote branch from the log

GitLab records the logs of all branch operations, including deletion operations. Therefore, you need to find the deleted branch by looking at GitLab's log records. From the log, you can get the name of the branch and the hash of the last commit.

2. Create a branch from the local code base

After completing the first step, you can re-create a branch in the local Git repository. Use the following command:

$ git checkout -b branch_name commit_hash

where branch_name is the name of the branch that was deleted, and commit_hash is the hash value of the last commit. It should be noted that the hash value of the new branch should be the same as the hash value in the remote code base to ensure data consistency.

3. Push the local branch to the remote code base

After completing the creation of the local branch, you can push the branch to the remote code base:

$ git push origin branch_name

Among them, branch_name Is the branch name that needs to be pushed to the remote code base. After the push is completed, you can view the branch through GitLab's web interface and allow other team members to collaborate on development.

In short, Git is a powerful code management tool that can achieve remote collaborative development through platforms such as GitLab. When using Git for team collaboration, the correctness of remote branches is important. To avoid accidentally deleting remote branches, this article explains how to prevent and resolve the problem. I hope it will be helpful to programmers using GitLab.
