In multi-person collaborative development projects, Git is a very important version control tool. However, in actual operation, code conflicts will occur because multiple people modify the same file at the same time. Resolving code conflicts is an essential skill that developers must master. This article will summarize the experience in resolving Git code conflicts from a practical perspective.
- Avoid code conflicts
First of all, we should avoid code conflicts as much as possible. How to do it?
- Assign code module. A module is maintained by only one person and cannot be modified by others. This avoids the situation where multiple people modify the same file at the same time.
- Informed in advance. If we need to modify the code that someone else is responsible for, we should inform the other party first to avoid overwriting each other.
- Try not to make modifications on the same branch, but use branch merging. After each developer completes development on his or her own branch, the code is merged into the main branch.
- How to resolve Git code conflicts
Although we try our best to avoid code conflicts, code conflicts are still inevitable. In this case, we need to deal with it in time, otherwise it will have a negative impact on the development progress of the project. The following are common solutions to Git code conflicts:
- Manual resolution. When Git prompts for a file conflict, we need to manually open the file, find the conflict, and manually resolve the conflict. Generally speaking, we can use a text editor to resolve conflicts, merge the code, and finally save the file.
- Use Git merge tool. Git provides some merge tools to help us quickly resolve code conflicts. For example, the "git mergetool" command can open the merge tool and let us merge code. If no merge tool is specified, "vimdiff" will be used by default.
- Undo local modifications. If we are not sure how to resolve the conflict, or cannot resolve the conflict, we can use the "git checkout -- " command to undo local modifications and re-obtain the latest code. However, this command will overwrite local modifications, so be very careful when using it.
- Notes on resolving Git code conflicts
When resolving Git code conflicts, you also need to pay attention to the following points:
- Keep valid codes. When resolving conflicts, we should keep valid code and delete useless code such as comments and spaces. This can make the code more concise and easy to understand for subsequent maintenance work.
- Back up modified files. Before resolving the conflict, we should back up the modified files to avoid errors when resolving the conflict and affect the normal development of the project.
- Check the code again before submitting. After resolving conflicts, we need to check the code again for errors and ensure that all tests pass before submitting.
In short, although code conflicts are unavoidable, we can reduce the incidence of code conflicts through some methods and master the solutions to code conflicts to ensure the smooth progress of the project.
