Summary of practical experience in resolving Git code conflicts

Introduction:
In team collaboration development, the use of version control systems is an indispensable part. As one of the most popular version control tools currently, Git provides developers with powerful and flexible functions. However, as the size of the team increases and the number of developers increases, the problem of code conflicts becomes more and more common. This article will summarize the causes of code conflicts, common conflict types, and practical experience in resolving conflicts. I hope it can be helpful to the majority of developers.

1. Causes of code conflicts
Code conflicts refer to conflicts between different parts of the same file in different branches or modifications. This is because multiple developers are working on the same line during parallel development. The code was modified differently. The main reasons leading to code conflicts are as follows:

1. Parallel development:
In multi-person collaborative development, each developer usually creates his own working branch from the trunk branch and then develops it in parallel. Different features or fix different bugs. When a branch is submitted to the trunk branch, if other branches also modify the same part of the code, conflicts will occur.

2. Branch merge:
When modifications from multiple branches are merged into the same branch, conflicts will occur if different modifications are made to the same part of the code.

3. File renaming or moving:
When renaming or moving a file, if other branches modify the file, conflicts will occur.

2. Common conflict types
There are many types of code conflicts. Here are several common conflict types:

1. Modification conflicts of the same line of code:
When multiple developers make different modifications to the same line of code, Git cannot automatically determine which modification should be retained, and conflicts will occur. The typical solution is to manually select the modifications that need to be retained or merge the two.

2. File rename conflict:
A conflict occurs when two branches rename the same file and make different modifications to the file after the rename. Resolving such conflicts requires manual judgment about how to handle renamed files and modifications within the files.

3. File move conflict:
When two branches move the same file and make different modifications to the file after the move, a conflict will occur. Resolving such conflicts requires manual judgment about how to handle the movement of files and the merging of modifications.

4. File deletion conflict:
When one branch deletes a file and another branch modifies the file, a conflict will occur. Resolving such conflicts requires manual judgment about how to handle the deletion of files and the merging of modifications.

3. Practical experience in resolving conflicts
In the face of code conflicts, we need to take a series of measures to resolve them. The following are some practical experiences in resolving conflicts:

1. Timely updates Code:
Before starting work, synchronize the code of the local warehouse with the online warehouse to ensure that you have the latest code when resolving conflicts.

2. Understand the causes of conflicts:
When resolving conflicts, you must first understand the causes and types of conflicts, so that you can better choose solutions.

3. Reasonable division of work tasks:
When multiple developers develop in parallel, reasonable division of work tasks can reduce the occurrence of conflicts. Prevent different developers from modifying the same parts of the same file at the same time and minimize the possibility of conflicts.

4. Frequent submission when merging code:
Before merging code, submit your modifications in time so that each unit of work is in a stable state. In this way, even if a conflict occurs, it can be quickly located and resolved.

5. Multi-person collaboration:
Multi-person collaboration is very important when resolving conflicts. Through communication and negotiation with other developers, we can jointly find the best solution to resolve conflicts.

6. Familiar with Git commands and tools:
Proficiency in common Git commands and tools, such as merge, rebase, and diff, can help to better resolve conflicts.

Conclusion:
Code conflicts are common and inevitable problems in team collaboration development. Resolving conflicts requires developers to have good communication and collaboration skills and proficient Git skills. Through timely updating of code, understanding of conflict causes, reasonable division of work tasks, frequent submission, multi-person collaboration, and familiarity with Git commands and tools, practical experience can help us better resolve conflicts, improve team collaboration efficiency, and ensure code quality.
