# Git 工作流模式
|
||
|
||
Git 版本控制、分支策略与协作开发的最佳实践。
|
||
|
||
## 何时启用
|
||
|
||
* 为新项目设置 Git 工作流
|
||
* 决定分支策略(GitFlow、主干开发、GitHub Flow)
|
||
* 编写提交信息和 PR 描述
|
||
* 解决合并冲突
|
||
* 管理发布和版本标签
|
||
* 让新团队成员熟悉 Git 实践
|
||
|
||
## 分支策略
|
||
|
||
### GitHub Flow(简单,推荐大多数场景使用)
|
||
|
||
最适合持续部署以及中小型团队。
|
||
|
||
```
|
||
main (protected, always deployable)
|
||
│
|
||
├── feature/user-auth → PR → merge to main
|
||
├── feature/payment-flow → PR → merge to main
|
||
└── fix/login-bug → PR → merge to main
|
||
```
|
||
|
||
**规则:**
|
||
|
||
* `main` 始终可部署
|
||
* 从 `main` 创建功能分支
|
||
* 准备就绪后发起 Pull Request
|
||
* 审核通过且 CI 通过后,合并到 `main`
|
||
* 合并后立即部署
|
||
|
||
### 主干开发(高速度团队)
|
||
|
||
最适合具备强大 CI/CD 和功能开关的团队。
|
||
|
||
```
|
||
main (主干)
|
||
│
|
||
├── 短期功能分支(最长1-2天)
|
||
├── 短期功能分支
|
||
└── 短期功能分支
|
||
```
|
||
|
||
**规则:**
|
||
|
||
* 所有人直接提交到 `main` 或使用极短生命周期的分支
|
||
* 功能开关隐藏未完成的工作
|
||
* 合并前必须通过 CI
|
||
* 每天多次部署
|
||
|
||
### GitFlow(复杂,基于发布周期)
|
||
|
||
适合计划性发布和企业级项目。
|
||
|
||
```
|
||
main (生产发布版本)
|
||
│
|
||
└── develop (集成分支)
|
||
│
|
||
├── feature/user-auth
|
||
├── feature/payment
|
||
│
|
||
├── release/1.0.0 → 合并到 main 和 develop
|
||
│
|
||
└── hotfix/critical → 合并到 main 和 develop
|
||
```
|
||
|
||
**规则:**
|
||
|
||
* `main` 仅包含生产就绪代码
|
||
* `develop` 是集成分支
|
||
* 功能分支从 `develop` 创建,合并回 `develop`
|
||
* 发布分支从 `develop` 创建,合并到 `main` 和 `develop`
|
||
* 热修复分支从 `main` 创建,合并到 `main` 和 `develop`
|
||
|
||
### 何时使用哪种策略
|
||
|
||
| 策略 | 团队规模 | 发布频率 | 最佳适用场景 |
|
||
|----------|-----------|-----------------|----------|
|
||
| GitHub Flow | 任意 | 持续 | SaaS、Web 应用、初创公司 |
|
||
| 主干开发 | 5 人以上有经验 | 每天多次 | 高速度团队、功能开关 |
|
||
| GitFlow | 10 人以上 | 计划性 | 企业、受监管行业 |
|
||
|
||
## 提交信息
|
||
|
||
### 常规提交格式
|
||
|
||
```
|
||
<type>(<scope>): <subject>
|
||
|
||
[optional body]
|
||
|
||
[optional footer(s)]
|
||
```
|
||
|
||
### 类型
|
||
|
||
| 类型 | 用途 | 示例 |
|
||
|------|---------|---------|
|
||
| `feat` | 新功能 | `feat(auth): add OAuth2 login` |
|
||
| `fix` | 错误修复 | `fix(api): handle null response in user endpoint` |
|
||
| `docs` | 文档 | `docs(readme): update installation instructions` |
|
||
| `style` | 格式调整,无代码变更 | `style: fix indentation in login component` |
|
||
| `refactor` | 代码重构 | `refactor(db): extract connection pool to module` |
|
||
| `test` | 添加/更新测试 | `test(auth): add unit tests for token validation` |
|
||
| `chore` | 维护任务 | `chore(deps): update dependencies` |
|
||
| `perf` | 性能改进 | `perf(query): add index to users table` |
|
||
| `ci` | CI/CD 变更 | `ci: add PostgreSQL service to test workflow` |
|
||
| `revert` | 回滚之前的提交 | `revert: revert "feat(auth): add OAuth2 login"` |
|
||
|
||
### 好与坏的示例
|
||
|
||
```
|
||
# 不好:模糊,无上下文
|
||
git commit -m "修复了一些东西"
|
||
git commit -m "更新"
|
||
git commit -m "进行中"
|
||
|
||
# 好:清晰,具体,解释原因
|
||
git commit -m "fix(api): 在 503 服务不可用时重试请求
|
||
|
||
外部 API 在高峰时段偶尔会返回 503 错误。
|
||
添加了指数退避重试逻辑,最多尝试 3 次。
|
||
|
||
关闭 #123"
|
||
```
|
||
|
||
### 提交信息模板
|
||
|
||
在仓库根目录创建 `.gitmessage`:
|
||
|
||
```
|
||
# <type>(<scope>): <subject>
|
||
# # 类型:feat, fix, docs, style, refactor, test, chore, perf, ci, revert
|
||
# 范围:api, ui, db, auth 等
|
||
# 主题:祈使语气,无句号,最多50个字符
|
||
#
|
||
# [可选正文] - 解释原因,而非内容
|
||
# [可选脚注] - 破坏性变更,关闭 #issue
|
||
```
|
||
|
||
启用方式:`git config commit.template .gitmessage`
|
||
|
||
## 合并 vs 变基
|
||
|
||
### 合并(保留历史)
|
||
|
||
```bash
|
||
# Creates a merge commit
|
||
git checkout main
|
||
git merge feature/user-auth
|
||
|
||
# Result:
|
||
# * merge commit
|
||
# |\
|
||
# | * feature commits
|
||
# |/
|
||
# * main commits
|
||
```
|
||
|
||
**适用场景:**
|
||
|
||
* 将功能分支合并到 `main`
|
||
* 希望保留完整历史
|
||
* 多人共同开发该分支
|
||
* 分支已推送,其他人可能基于它开展工作
|
||
|
||
### 变基(线性历史)
|
||
|
||
```bash
|
||
# Rewrites feature commits onto target branch
|
||
git checkout feature/user-auth
|
||
git rebase main
|
||
|
||
# Result:
|
||
# * feature commits (rewritten)
|
||
# * main commits
|
||
```
|
||
|
||
**适用场景:**
|
||
|
||
* 用最新的 `main` 更新本地功能分支
|
||
* 希望获得线性、干净的历史
|
||
* 分支仅存在于本地(未推送)
|
||
* 只有你一个人在该分支上工作
|
||
|
||
### 变基工作流
|
||
|
||
```bash
|
||
# Update feature branch with latest main (before PR)
|
||
git checkout feature/user-auth
|
||
git fetch origin
|
||
git rebase origin/main
|
||
|
||
# Fix any conflicts
|
||
# Tests should still pass
|
||
|
||
# Force push (only if you're the only contributor)
|
||
git push --force-with-lease origin feature/user-auth
|
||
```
|
||
|
||
### 何时不应变基
|
||
|
||
```
|
||
# 切勿变基以下分支:
|
||
- 已推送至共享仓库的分支
|
||
- 他人已基于其工作的分支
|
||
- 受保护分支(main、develop)
|
||
- 已合并的分支
|
||
|
||
# 原因:变基会重写历史,破坏他人的工作
|
||
```
|
||
|
||
## Pull Request 工作流
|
||
|
||
### PR 标题格式
|
||
|
||
```
|
||
<type>(<scope>): <description>
|
||
|
||
示例:
|
||
feat(auth): add SSO support for enterprise users
|
||
fix(api): resolve race condition in order processing
|
||
docs(api): add OpenAPI specification for v2 endpoints
|
||
```
|
||
|
||

||
## 冲突解决
|
||
|
||
### 识别冲突
|
||
|
||
```bash
|
||
# Check for conflicts before merge
|
||
git checkout main
|
||
git merge feature/user-auth --no-commit --no-ff
|
||
|
||
# If conflicts, Git will show:
|
||
# CONFLICT (content): Merge conflict in src/auth/login.ts
|
||
# Automatic merge failed; fix conflicts and then commit the result.
|
||
```
|
||
|
||
### 解决冲突
|
||
|
||
```bash
|
||
# See conflicted files
|
||
git status
|
||
|
||
# View conflict markers in file
|
||
# <<<<<<< HEAD
|
||
# content from main
|
||
# =======
|
||
# content from feature branch
|
||
# >>>>>>> feature/user-auth
|
||
|
||
# Option 1: Manual resolution
|
||
# Edit file, remove markers, keep correct content
|
||
|
||
# Option 2: Use merge tool
|
||
git mergetool
|
||
|
||
# Option 3: Accept one side
|
||
git checkout --ours src/auth/login.ts # Keep main version
|
||
git checkout --theirs src/auth/login.ts # Keep feature version
|
||
|
||
# After resolving, stage and commit
|
||
git add src/auth/login.ts
|
||
git commit
|
||
```
|
||
|
||
### 冲突预防策略
|
||
|
||
```bash
|
||
# 1. Keep feature branches small and short-lived
|
||
# 2. Rebase frequently onto main
|
||
git checkout feature/user-auth
|
||
git fetch origin
|
||
git rebase origin/main
|
||
|
||
# 3. Communicate with team about touching shared files
|
||
# 4. Use feature flags instead of long-lived branches
|
||
# 5. Review and merge PRs promptly
|
||
```
|
||
|
||
## 分支管理
|
||
|
||
### 命名规范
|
||
|
||
```
|
||
# 功能分支
|
||

|
||
feature/JIRA-123-payment-integration
|
||
|
||
# 错误修复
|
||
fix/login-redirect-loop
|
||
fix/456-null-pointer-exception
|
||
|
||
# 热修复(生产问题)
|
||
hotfix/critical-security-patch
|
||
hotfix/database-connection-leak
|
||
|
||
# 发布版本

|
||
poc/graphql-migration
|
||
```
|
||
|
||
### 分支清理
|
||
|
||
```bash
|
||
# Delete local branches that are merged
|
||
git branch --merged main | grep -v "^\*\|main" | xargs -n 1 git branch -d
|
||
|
||
# Delete remote-tracking references for deleted remote branches
|
||
git fetch -p
|
||
|
||
# Delete local branch
|
||
git branch -d feature/user-auth # Safe delete (only if merged)
|
||
git branch -D feature/user-auth # Force delete
|
||
|
||
# Delete remote branch
|
||
git push origin --delete feature/user-auth
|
||
```
|
||
|
||
### 暂存工作流
|
||
|
||
```bash
|
||
# Save work in progress
|
||
git stash push -m "WIP: user authentication"
|
||
|
||
# List stashes
|
||
git stash list
|
||
|
||
# Apply most recent stash
|
||
git stash pop
|
||
|
||
# Apply specific stash
|
||
git stash apply stash@{2}
|
||
|
||
# Drop stash
|
||
git stash drop stash@{0}
|
||
```
|
||
|
||
## 发布管理
|
||
|
||
### 语义化版本
|
||
|
||
```
|
||
MAJOR.MINOR.PATCH
|
||
|
||
MAJOR:破坏性变更
|
||
MINOR:新功能,向后兼容
|
||
PATCH:错误修复,向后兼容
|
||
|
||
示例:
|
||
1.0.0 → 1.0.1(补丁:错误修复)
|
||
1.0.1 → 1.1.0(次要:新功能)
|
||
1.1.0 → 2.0.0(主要:破坏性变更)
|
||
```
|
||
|
||
### 创建发布
|
||
|
||
```bash
|
||
# Create annotated tag
|
||
git tag -a v1.2.0 -m "Release v1.2.0
|
||
|
||
Features:
|
||
- Add user authentication
|
||
- Implement password reset
|
||
|
||
Fixes:
|
||
- Resolve login redirect issue
|
||
|
||
Breaking Changes:
|
||
- None"
|
||
|
||
# Push tag to remote
|
||
git push origin v1.2.0
|
||
|
||
# List tags
|
||
git tag -l
|
||
|
||
# Delete tag
|
||
git tag -d v1.2.0
|
||
git push origin --delete v1.2.0
|
||
```
|
||
|
||
### 变更日志生成
|
||
|
||
```bash
|
||
# Generate changelog from commits
|
||
git log v1.1.0..v1.2.0 --oneline --no-merges
|
||
|
||
# Or use conventional-changelog
|
||
npx conventional-changelog -i CHANGELOG.md -s
|
||
```
|
||
|
||
## Git 配置
|
||
|
||
### 基本配置
|
||
|
||
```bash
|
||
# User identity
|
||
git config --global user.name "Your Name"
|
||
git config --global user.email "your@email.com"
|
||
|
||
# Default branch name
|
||
git config --global init.defaultBranch main
|
||
|
||
# Pull behavior (rebase instead of merge)
|
||
git config --global pull.rebase true
|
||
|
||
# Push behavior (push current branch only)
|
||
git config --global push.default current
|
||
|
||
# Auto-correct typos
|
||
git config --global help.autocorrect 1
|
||
|
||
# Better diff algorithm
|
||
git config --global diff.algorithm histogram
|
||
|
||
# Color output
|
||
git config --global color.ui auto
|
||
```
|
||
|
||
### 实用别名
|
||
|
||
```bash
|
||
# Add to ~/.gitconfig
|
||
[alias]
|
||
co = checkout
|
||
br = branch
|
||
ci = commit
|
||
st = status
|
||
unstage = reset HEAD --
|
||
last = log -1 HEAD
|
||
visual = log --oneline --graph --all
|
||
amend = commit --amend --no-edit
|
||
wip = commit -m "WIP"
|
||
undo = reset --soft HEAD~1
|
||
contributors = shortlog -sn
|
||
```
|
||
|
||
### Gitignore 模式

## 常见工作流
|
||
|
||
### 开始新功能
|
||
|
||
```bash
|
||
# 1. Update main branch
|
||
git checkout main
|
||
git pull origin main
|
||
|
||
# 2. Create feature branch
|
||
git checkout -b feature/user-auth
|
||
|
||
# 3. Make changes and commit
|
||
git add .
|
||
git commit -m "feat(auth): implement OAuth2 login"
|
||
|
||
# 4. Push to remote
|
||
git push -u origin feature/user-auth
|
||
|
||
# 5. Create Pull Request on GitHub/GitLab
|
||
```
|
||
|
||
### 用新变更更新 PR
|
||
|
||
```bash
|
||
# 1. Make additional changes
|
||
git add .
|
||
git commit -m "feat(auth): add error handling"
|
||
|
||
# 2. Push updates
|
||
git push origin feature/user-auth
|
||
```
|
||
|
||
### 同步 Fork 与上游
|
||
|
||
```bash
|
||
# 1. Add upstream remote (once)
|
||
git remote add upstream https://github.com/original/repo.git
|
||
|
||
# 2. Fetch upstream
|
||
git fetch upstream
|
||
|
||
# 3. Merge upstream/main into your main
|
||
git checkout main
|
||
git merge upstream/main
|
||
|
||
# 4. Push to your fork
|
||
git push origin main
|
||
```
|
||
|
||
### 撤销错误操作
|
||
|
||
```bash
|
||
# Undo last commit (keep changes)
|
||
git reset --soft HEAD~1
|
||
|
||
# Undo last commit (discard changes)
|
||
git reset --hard HEAD~1
|
||
|
||
# Undo last commit pushed to remote
|
||
git revert HEAD
|
||
git push origin main
|
||
|
||
# Undo specific file changes
|
||
git checkout HEAD -- path/to/file
|
||
|
||
# Fix last commit message
|
||
git commit --amend -m "New message"
|
||
|
||
# Add forgotten file to last commit
|
||
git add forgotten-file
|
||
git commit --amend --no-edit
|
||
```
|
||
|
||
## Git 钩子
|
||
|
||
### 预提交钩子
|
||
|
||
```bash
|
||
#!/bin/bash
|
||
# .git/hooks/pre-commit
|
||
|
||
# Run linting
|
||
npm run lint || exit 1
|
||
|
||
# Run tests
|
||
npm test || exit 1
|
||
|
||
# Check for secrets
|
||
if git diff --cached | grep -E '(password|api_key|secret)'; then
|
||
echo "Possible secret detected. Commit aborted."
|
||
exit 1
|
||
fi
|
||
```
|
||
|
||
### 预推送钩子
|
||
|
||
```bash
|
||
#!/bin/bash
|
||
# .git/hooks/pre-push
|
||
|
||
# Run full test suite
|
||
npm run test:all || exit 1
|
||
