GitLab's multi-warehouse collaborative workflow and practice

[Introduction]
In the software development process, especially in large projects, simultaneous maintenance is usually required Multiple code repositories. As a powerful code hosting platform, GitLab provides various functions to support collaborative work of multiple warehouses. This article will introduce GitLab's multi-warehouse collaborative workflow and practice, and provide specific code examples.

[Multi-warehouse collaborative work process]

1. Create a main warehouse: First create a main warehouse, which is used to manage the main code of the project. We can create a new project on GitLab and clone the project locally.
   Sample code:

   git clone <主仓库地址>

2. Create sub-warehouse: Next, we can create one or more sub-warehouses to manage different modules or functions. Each sub-repository can be developed independently and integrated with the main repository when needed.
   Sample code:

   git clone <子仓库地址>

3. Create branches: In the main warehouse and sub-warehouses, we can create multiple branches as needed for different development tasks or version iterations. Each branch can be developed independently and merged when complete.
   Sample code:

   git checkout -b <分支名>

4. Development and submission: Carry out development work on the corresponding branches of each warehouse, and regularly submit code to the remote warehouse. Developers can use regular Git commands for code submission, such as add, commit, and push.
   Sample code:

   git add .
   git commit -m "提交说明"
   git push origin <分支名>

5. Merge branches: When the development work of a branch is completed, it can be merged into other branches or the main warehouse. In GitLab, you can use merge requests to review and merge code.
   Sample code (merging branches into the main repository):

   git checkout <主仓库分支>
   git merge <子仓库分支>
   git push origin <主仓库分支>

6. Resolving conflicts: When merging branches, code conflicts may occur. Conflicts usually occur when multiple branches modify the same code and then merge it. In GitLab, conflicts can be resolved using the conflict resolution tool on the merge request page.
   Sample code (conflict resolution):

   git checkout <主仓库分支>
   git merge <子仓库分支>
   # 解决冲突后，执行以下命令
   git add .
   git commit -m "解决冲突"
   git push origin <主仓库分支>

7. Regular updates: In the process of multi-warehouse collaboration, in order to keep each warehouse synchronized, we need to regularly update the latest codes of other warehouses . You can use the git pull command to pull updates from the remote repository.
   Sample code (pull the latest code):

   git pull origin <主仓库分支>

[Sample scenario]
Suppose we have a main warehouse for managing the core functions of the project, and two sub-warehouses The repository is used to develop plug-ins for the project. We can perform multi-warehouse collaborative work according to the following process:

1. Clone the main warehouse to the local:

   git clone <主仓库地址>

2. Clone the sub-warehouse to the local:

   git clone <子仓库1地址>
   git clone <子仓库2地址>

3. Create and switch to the development branch of the main warehouse:

   cd <主仓库目录>
   git checkout -b feature/main-development

4. Develop on the development branch of the main warehouse and submit code regularly:

   # ... 进行开发工作 ...
   git add .
   git commit -m "完成主仓库功能开发"
   git push origin feature/main-development

5. Switch to the development branch of sub-repository 1 and merge the code from the development branch of the main repository:

   cd <子仓库1目录>
   git checkout -b feature/plugin1-development
   git merge origin/feature/main-development
   git push origin feature/plugin1-development

6. Switch to the development branch of sub-repository 2 Branch and merge the code from the development branch of the main repository:

   cd <子仓库2目录>
   git checkout -b feature/plugin2-development
   git merge origin/feature/main-development
   git push origin feature/plugin2-development

7. Create a merge request (Merge Request) on GitLab to merge the development branch of the sub-repository into the development branch of the main repository for code review and merge operations.

8. Regularly update the latest code of the warehouse:

   cd <子仓库1目录>
   git pull origin feature/main-development
   
   cd <子仓库2目录>
   git pull origin feature/main-development

[Summary]
Through GitLab's multi-warehouse collaborative work process, we can easily manage and Coordinate development work across multiple code repositories. Whether you are developing a main repository or maintaining a sub-repository, you can achieve efficient code collaboration through the powerful functions provided by GitLab. We hope that the introduction and examples in this article can help readers better understand and apply GitLab's multi-warehouse collaborative workflow.
