How to find the previous version on gitlab

Git is a very powerful code version control system. It can help developers save various versions of the code and improve code controllability and quality. During the development process, it is likely that you need to find a previous version or roll back to a previous version. This article will introduce how to find previous versions on GitLab.

1. Git version control basics

In Git, each version has a unique identifier, which can be viewed on the command line through the git log command. Each version contains code modification and submission information. When we need to find a previous version, we can do it through Git's version control mechanism.

Git's version control mechanism mainly includes three areas: work area, staging area and warehouse. The workspace is the code file we are editing, the staging area is the area where we place the modified files, and the warehouse is the place where we store the code. Every time we modify the files in the workspace and place the modified files in the staging area, we can then submit the files in the staging area to the warehouse, thus forming a new version.

2. Find previous versions on GitLab

GitLab is a Git-based web platform that helps us manage code, version control and collaborative development. To find the previous version on GitLab, we can do it through the following steps:

Step 1: Enter the code library

First, enter the code library on GitLab and select the project for which you want to find the historical version.

Step 2: View historical versions

In the code base, we can see a "History" button. Click it to view all historical versions of the current project. If we need to find a specific version, we can enter keywords or time ranges to filter among historical versions.

Step 3: View the detailed information of a certain version

In the historical version, we can select a certain version and then view the detailed information of that version. In the details page, you can view the submitter, submission time, submission information and other information, and you can also compare and restore the versions.

Step 4: Restore a certain version

Sometimes we need to restore to a previous version. You can select the "Restore" operation in the details page of the version to restore the current version. The code base is restored to the state of that version.

3. Summary

Finding previous versions on GitLab is a very common operation and one of the important means of managing code versions. In the actual development process, we need to frequently use Git's version control mechanism to find previous versions as needed and restore or compare them. By using GitLab's historical version function, we can easily perform these operations and improve the controllability and quality of the code.
