In the software development process, version control is a very important link. Git is a widely used distributed version control system. It is very flexible and easy to use, and is loved by many developers. GitLab is a web management tool based on Git. It provides code hosting, issue tracking, CI/CD and other functions. It is widely used in code management, continuous integration and continuous deployment. However, sometimes we may need to restore the code base to a previous version due to misoperation or other reasons. Under normal circumstances, you can use reset or revert in Git to roll back a version, but how to implement it on GitLab? This article will give some solutions.

First of all, we need to make it clear that GitLab, as a management platform based on Git, actually provides a graphical operation interface for Git functions. Therefore, many Git operations can actually be implemented on GitLab.

  1. Use GitLab's version rollback function

In every project of GitLab, we can find a History option. After clicking to enter, you can see the complete List of submission records. In this page, each submission has a unique SHA value, and we can locate the target submission based on this value.

If we want to roll back to a historical version, we only need to click the Revert button on the right side of the version, and then fill in the submission information in the pop-up window.

However, it should be noted that when using this method to roll back, GitLab actually creates a new submission to undo the previous submission, so the previous submission will not be deleted. This means that although everyone can see this new commit, in fact, the previous commit still exists in the code base, and we can still retrieve the previous code if needed.

  1. Using GitLab's rollback function

In the GitLab project management page, if we click on the Commit column, we can see the history of all submissions. Any user can use the rollback button on this page to roll back the code to a historical version.

However, unlike the above method, the rollback function actually deletes the previous commit and replaces it with a new commit that undoes the commit. This means that after a rollback, the previous commit will no longer appear in the code base, but will be completely deleted.

When we click the rollback button, GitLab will pop up a window asking us if we are sure to rollback. If it is determined, GitLab will delete the current commit and create a new one that undoes the commit. It should be noted that since this operation may affect the work of other people, it is best to communicate with other relevant team members before performing the operation.

  1. Use the command line for rollback

In addition to the graphical operation interface provided by GitLab, we can also use the command line to perform rollback operations. Similar to ordinary Git operations, we can use git reset or git revert to roll back to historical versions. However, since GitLab is a web management platform, if you use the command line to roll back, you need to interact with GitLab on the command line. The specific operations are as follows:

First, we need to obtain the warehouse address of the GitLab project, which is usually https://gitlab.com/[user]/[project_name].git. We can find this address on the project's page.

Then, we need to use the git clone command to clone the project locally.

Next, we can use the git log command to view the submission records in the local code base. After finding the historical version that needs to be rolled back, we can use the git reset or git revert command to perform the rollback operation.

It should be noted that after the rollback operation is completed, we need to push the code to GitLab so that others can also see the rolled back code.

Summary

Version control is an important link that cannot be ignored in the software development process, and rolling back the version is also an important operation. On the GitLab platform, we can use its own version rollback function and rollback function, or we can use the command line to operate. However, before rolling back, we need to carefully consider the impact it may have on the work of other team members and fully communicate with them.
