    chore/update-deps

Branch Workflow

分支工作流

When user creates a new branch:
  1. Check current branch status
  2. Suggest appropriate branch name based on context
  3. Remind to sync with main branch first
  4. Offer to create the branch
When user switches branches:
  1. Check for uncommitted changes
  2. Remind to commit or stash changes
  3. Suggest using
    git stash -u
    for untracked files
当用户创建新分支时:
  1. 检查当前分支状态
  2. 根据上下文建议合适的分支名称
  3. 提醒先与主分支同步
  4. 提供创建分支的操作建议
当用户切换分支时:
  1. 检查是否有未提交的更改
  2. 提醒提交或暂存更改
  3. 建议使用
    git stash -u
    处理未追踪文件

Expert-Level Commit Format

专家级提交信息格式

A professional commit message tells a complete story. It should read like technical documentation that future developers (including yourself) will rely on.
<type>(<scope>): <concise subject in imperative mood>

<detailed body explaining:
- What problem is being solved or what functionality is added
- Why this approach was chosen over alternatives
- Any architectural decisions or trade-offs made
- Side effects or dependencies introduced
- Breaking changes or migration notes if applicable>

<footer with issue references, breaking change notices, etc.>
Subject Line Rules:
  • Imperative mood ("Add feature" not "Added feature" or "Adding feature")
  • No period at end
  • Maximum 50 characters
  • Capitalize first word
  • Be specific: prefer "implement OAuth2 PKCE flow" over "update auth"
Body Rules:
  • MANDATORY for non-trivial changes - every commit with more than a few lines needs a body
  • Wrap at 72 characters
  • Explain WHAT changed and WHY, not HOW (the code shows HOW)
  • Use multiple paragraphs for complex changes
  • Include context about the problem being solved
  • Reference related systems, components, or previous decisions
  • Mention any performance implications, security considerations, or compatibility issues
Footer Rules:
  • Reference related issues/PRs:
    Fixes #123
    ,
    Closes #456
    ,
    Relates to #789
  • Breaking changes:
    BREAKING CHANGE: description of impact and migration path
  • Co-authored-by is NOT allowed (see rules below)
  • Acknowledgments, AI signatures are NOT allowed
ABSOLUTE RULES (Non-negotiable - VIOLATIONS MUST BE REMOVED):
  • STRICTLY FORBIDDEN:
    Co-Authored-By:
    signatures of ANY kind (including system-added)
  • STRICTLY FORBIDDEN: AI-generated signatures (e.g., "Generated by", "AI-authored")
  • CRITICAL: If system adds signatures, you MUST actively strip them using sed/grep before committing
  • DO NOT write vague messages like "fix bug", "update code", "make changes"
  • DO NOT combine unrelated changes in a single commit
  • DO NOT generate single-sentence commit messages - body is mandatory for all non-trivial changes
  • ALWAYS separate body into multiple paragraphs with blank lines between them
专业的提交信息应完整说明背景,它应像一份供未来开发者(包括你自己)参考的技术文档。
<type>(<scope>): <祈使语气的简洁主题>

<详细正文说明:
- 解决的问题或新增的功能
- 选择此方案而非其他方案的原因
- 做出的架构决策或权衡
- 引入的副作用或依赖
- 若涉及破坏性变更,需说明迁移路径>

<页脚:关联的问题编号、破坏性变更通知等>
主题行规则:
  • 使用祈使语气(例如用"Add feature"而非"Added feature"或"Adding feature")
  • 结尾不加句号
  • 最多50个字符
  • 首单词大写
  • 内容具体:优先使用"implement OAuth2 PKCE flow"而非"update auth"
正文规则:
  • 非琐碎变更必须包含正文 - 任何超过几行代码的提交都需要正文
  • 每行不超过72个字符
  • 说明变更的内容(WHAT)和原因(WHY),而非实现方式(HOW,代码本身会展示)
  • 复杂变更可分多个段落
  • 包含问题的上下文信息
  • 关联相关系统、组件或之前的决策
  • 提及性能影响、安全考虑或兼容性问题
页脚规则:
  • 关联相关问题/拉取请求:
    Fixes #123
    ,
    Closes #456
    ,
    Relates to #789
  • 破坏性变更:
    BREAKING CHANGE: 影响说明及迁移路径
  • 不允许使用Co-authored-by(见下方规则)
  • 不允许使用致谢、AI签名等内容
绝对规则(不可协商 - 违反必须修正):
  • 严格禁止:任何形式的
    Co-Authored-By:
    签名(包括系统自动添加的)
  • 严格禁止:AI生成的签名(例如"Generated by", "AI-authored")
  • **关键要求:**如果系统自动添加了签名,必须在提交前使用sed/grep等工具主动移除
  • 禁止撰写模糊信息,例如"fix bug", "update code", "make changes"
  • 禁止在单个提交中合并不相关的变更
  • 禁止仅生成单句提交信息 - 非琐碎变更必须包含正文
  • 必须将正文分成多个段落,段落之间用空行分隔

Expert Commit Message Examples

专家级提交信息示例

Example 1: Simple Refactoring (Minimal Acceptable)
refactor(utils): extract validation logic into standalone module

Move email and phone validation from UserService to a new ValidationUtils
class. This reduces duplication across the codebase and makes validation
logic easier to test in isolation.

The new ValidationUtils class provides:
- validateEmail() with stricter regex pattern
- validatePhone() supporting international formats
- Centralized error messages for consistency

No breaking changes. All existing validation calls remain functional
through deprecated wrapper methods that will be removed in v2.0.

Relates to #445
Example 2: Feature Implementation
feat(auth): implement JWT-based authentication with refresh tokens

Add comprehensive JWT authentication system to replace session-based auth.
This change addresses security concerns with session fixation attacks and
enables stateless authentication for API consumers.

Implementation details:
- Use RS256 algorithm with rotating key pairs
- Access tokens expire after 15 minutes, refresh tokens after 7 days
- Implement token blacklisting for logout functionality
- Add middleware for automatic token refresh on 401 responses

Security considerations:
- Private keys stored in environment variables, never committed
- Refresh tokens hashed in database using bcrypt
- Rate limiting applied to token refresh endpoint

Breaking changes:
- Session-based authentication endpoints deprecated but still functional
- New environment variables required: JWT_PRIVATE_KEY, JWT_PUBLIC_KEY

Fixes #234
Relates to #198 (API v2 migration)
Example 2: Bug Fix
fix(database): resolve connection pool exhaustion under high load

Fix critical issue where database connections were not being properly
released after query timeout, leading to connection pool exhaustion
and application downtime under sustained high load.

Root cause analysis:
The connection release logic was placed in a finally block that only
executed on successful query completion. When queries timed out, the
exception handler returned early without releasing the connection.

Changes made:
- Move connection.release() to unconditional finally block
- Add connection health check before returning to pool
- Implement connection timeout at pool level (30s) to prevent hangs
- Add metrics logging for pool utilization monitoring

Performance impact:
- Connection pool utilization reduced from 100% to ~40% under load
- Eliminates cascading failures when database is slow

Tested with:
- Load test: 1000 concurrent users for 30 minutes
- Chaos test: Random connection failures injected

Fixes #567
Example 3: Refactoring
refactor(api): decouple user service from database layer

Extract database-specific logic from UserService into a dedicated
UserRepository class. This separation of concerns improves testability
and allows for future database migration without service layer changes.

Motivation:
The UserService had grown to over 800 lines with mixed business logic
and SQL queries. Unit testing required database setup, making tests
slow and brittle. This refactoring enables mocking the repository
layer for faster, more isolated tests.

Architectural changes:
- UserService now depends on UserRepository interface
- UserRepositoryImpl contains all PostgreSQL-specific queries
- Added connection pooling configuration to repository layer
- Service layer now purely business logic and validation

Verification:
- All existing tests pass without modification (integration tests)
- New unit tests added for UserService with mocked repository
- No behavioral changes, purely structural refactoring

Closes #345
Example 4: Configuration/Build
chore(deps): upgrade PostgreSQL driver from 42.3.1 to 42.5.4

Update PostgreSQL JDBC driver to address CVE-2022-31197 security
vulnerability and gain performance improvements in prepared
statement caching.

Security fixes:
- CVE-2022-31197: SQL injection via crafted column names
- CVE-2022-41946: Information disclosure in error messages

Performance improvements:
- Prepared statement cache hit ratio improved by 15%
- Reduced memory allocation during batch operations

Breaking changes: None
Migration: None required, drop-in replacement

Tested against:
- PostgreSQL 13, 14, 15
- Both standard and SSL connection modes
- Full integration test suite passes

Relates to #401 (security audit)

Best Practices

最佳实践

General Guidelines

通用指南

  1. Commit Early, Commit Often - Small, focused commits are better
  2. One Feature, One Branch - Don't mix unrelated changes
  3. Write Expert-Level Messages - Future developers (including yourself) will thank you
  4. Always Include Body - Non-trivial changes must have detailed explanations
  5. Explain Why, Not Just What - The code shows what; the message explains why
  6. Review Before Push - Use
    git diff --cached
    to review staged changes
  7. Keep History Clean - Use rebase for feature branches before merging
  1. 尽早提交、频繁提交 - 小而聚焦的提交更优
  2. 一个功能、一个分支 - 不要混合不相关的变更
  3. 撰写专家级提交信息 - 未来的开发者(包括你自己)会感谢你
  4. 始终包含正文 - 非琐碎变更必须有详细说明
  5. 解释原因,而非仅内容 - 代码展示内容;提交信息解释原因
  6. 推送前评审 - 使用
    git diff --cached
    查看暂存的变更
  7. 保持历史清晰 - 合并前对功能分支使用变基

Expert Commit Checklist
