## Security Checks (CRITICAL)
|
||||
## 安全检查(严重 CRITICAL)
|
||||
|
||||
- **SQL Injection**: String concatenation in `database/sql` queries
|
||||
- **SQL 注入 (SQL Injection)**: `database/sql` 查询中的字符串拼接
|
||||
```go
|
||||
// Bad
|
||||
// 错误示例 (Bad)
|
||||
db.Query("SELECT * FROM users WHERE id = " + userID)
|
||||
// Good
|
||||
// 正确示例 (Good)
|
||||
db.Query("SELECT * FROM users WHERE id = $1", userID)
|
||||
```
|
||||
|
||||
- **Command Injection**: Unvalidated input in `os/exec`
|
||||
- **命令注入 (Command Injection)**: `os/exec` 中未经验证的输入
|
||||
```go
|
||||
// Bad
|
||||
// 错误示例 (Bad)
|
||||
exec.Command("sh", "-c", "echo " + userInput)
|
||||
// Good
|
||||
// 正确示例 (Good)
|
||||
exec.Command("echo", userInput)
|
||||
```
|
||||
|
||||
- **Path Traversal**: User-controlled file paths
|
||||
- **路径遍历 (Path Traversal)**: 用户控制的文件路径
|
||||
```go
|
||||
// Bad
|
||||
// 错误示例 (Bad)
|
||||
os.ReadFile(filepath.Join(baseDir, userPath))
|
||||
// Good
|
||||
// 正确示例 (Good)
|
||||
cleanPath := filepath.Clean(userPath)
|
||||
if strings.HasPrefix(cleanPath, "..") {
|
||||
return ErrInvalidPath
|
||||
}
|
||||
```
|
||||
|
||||
- **Race Conditions**: Shared state without synchronization
|
||||
- **Unsafe Package**: Use of `unsafe` without justification
|
||||
- **Hardcoded Secrets**: API keys, passwords in source
|
||||
- **Insecure TLS**: `InsecureSkipVerify: true`
|
||||
- **Weak Crypto**: Use of MD5/SHA1 for security purposes
|
||||
- **竞态条件 (Race Conditions)**: 未经同步的共享状态
|
||||
- **Unsafe 包**: 无正当理由使用 `unsafe` 包
|
||||
- **硬编码凭据 (Hardcoded Secrets)**: 源码中包含 API 密钥、密码等
|
||||
- **不安全的 TLS**: 设置了 `InsecureSkipVerify: true`
|
||||
- **弱加密算法**: 出于安全目的使用 MD5/SHA1
|
||||
|
||||
## Error Handling (CRITICAL)
|
||||
## 错误处理(严重 CRITICAL)
|
||||
|
||||
- **Ignored Errors**: Using `_` to ignore errors
|
||||
- **忽略错误**: 使用 `_` 忽略错误
|
||||
```go
|
||||
// Bad
|
||||
// 错误示例 (Bad)
|
||||
result, _ := doSomething()
|
||||
// Good

||||
// 正确示例 (Good)
|
||||
result, err := doSomething()
|
||||
if err != nil {
|
||||
return fmt.Errorf("do something: %w", err)
|
||||
}
|
||||
```
|
||||
|
||||
- **Missing Error Wrapping**: Errors without context
|
||||
- **缺失错误封装 (Missing Error Wrapping)**: 错误缺乏上下文信息
|
||||
```go
|
||||
// Bad
|
||||
// 错误示例 (Bad)
|
||||
return err
|
||||
// Good
|
||||
// 正确示例 (Good)
|
||||
return fmt.Errorf("load config %s: %w", path, err)
|
||||
```
|
||||
|
||||
- **Panic Instead of Error**: Using panic for recoverable errors
|
||||
- **errors.Is/As**: Not using for error checking
|
||||
- **使用 Panic 代替错误返回**: 对可恢复的错误使用 panic
|
||||
- **errors.Is/As**: 未使用专门的函数进行错误检查
|
||||
```go
|
||||
// Bad
|
||||
// 错误示例 (Bad)
|
||||
if err == sql.ErrNoRows
|
||||
// Good
|
||||
// 正确示例 (Good)
|
||||
if errors.Is(err, sql.ErrNoRows)
|
||||
```

## Concurrency (HIGH)
|
||||
## 并发(高危 HIGH)
|
||||
|

- **Goroutine Leaks**: Goroutines that never terminate
|
||||
- **Goroutine 泄漏**: 永远不会终止的 Goroutine

- **Deep Nesting**: More than 4 levels of indentation
|

## Performance (MEDIUM)
|
||||
## 性能(中等 MEDIUM)
|
||||
|
||||
- **Inefficient String Building**:
|
||||
- **低效的字符串拼接**:
|
||||
```go
|
||||

|
||||
// 错误示例 (Bad)
|
||||
for _, s := range parts { result += s }
|

// Good
|

|
||||
var sb strings.Builder
|
||||
for _, s := range parts { sb.WriteString(s) }
|
||||
```
|
||||
|
||||
- **Slice Pre-allocation**: Not using `make([]T, 0, cap)`
|
||||
- **Pointer vs Value Receivers**: Inconsistent usage
|
||||
- **Unnecessary Allocations**: Creating objects in hot paths
|
||||
- **N+1 Queries**: Database queries in loops
|
||||
- **Missing Connection Pooling**: Creating new DB connections per request
|
||||
- **切片预分配**: 未使用 `make([]T, 0, cap)`
|
||||
- **指针与值接收者**: 使用不一致
|
||||
- **不必要的分配**: 在热点路径(hot paths)中频繁创建对象
|
||||
- **N+1 查询**: 在循环中执行数据库查询
|
||||
- **缺失连接池**: 为每个请求创建新的数据库连接
|
||||
|
||||
## Best Practices (MEDIUM)
|
||||
## 最佳实践(中等 MEDIUM)
|
||||
|
||||
- **Accept Interfaces, Return Structs**: Functions should accept interface parameters
|
||||
- **Context First**: Context should be first parameter
|
||||
- **接受接口,返回结构体 (Accept Interfaces, Return Structs)**: 函数应接受接口参数
|
||||
- **上下文(Context)优先**: Context 应作为第一个参数
|
||||
```go
|
||||
// Bad
|
||||
// 错误示例 (Bad)
|
||||
func Process(id string, ctx context.Context)
|
||||
// Good
|
||||
// 正确示例 (Good)
|
||||
func Process(ctx context.Context, id string)
|
||||
```
|
||||
|
||||
- **Table-Driven Tests**: Tests should use table-driven pattern
|
||||
- **Godoc Comments**: Exported functions need documentation
|
||||
- **表格驱动测试 (Table-Driven Tests)**: 测试应使用表格驱动模式
|
||||
- **Godoc 注释**: 导出的函数需要文档说明
|
||||
```go
|
||||
// ProcessData transforms raw input into structured output.
|
||||
// It returns an error if the input is malformed.
|
||||
// ProcessData 将原始输入转换为结构化输出。
|
||||
// 如果输入格式错误,它将返回一个错误。
|
||||
func ProcessData(input []byte) (*Data, error)
|
||||
```
|
||||
|
||||
- **Error Messages**: Should be lowercase, no punctuation
|
||||
- **错误消息**: 应小写,不带标点符号
|
||||
```go
|
||||
// Bad
|
||||
// 错误示例 (Bad)
|
||||
return errors.New("Failed to process data.")
|
||||
// Good
|
||||
// 正确示例 (Good)
|
||||
return errors.New("failed to process data")
|
||||
```
|
||||
|
||||
- **Package Naming**: Short, lowercase, no underscores
|
||||
- **包命名**: 简短、小写、不带下划线
|
||||
|
||||
## Go-Specific Anti-Patterns
|
||||
## Go 特有的反模式
|
||||
|
||||
- **init() Abuse**: Complex logic in init functions
|
||||
- **Empty Interface Overuse**: Using `interface{}` instead of generics
|
||||
- **Type Assertions Without ok**: Can panic
|
||||
- **init() 滥用**: 在 init 函数中编写复杂逻辑
|
||||
- **过度使用空接口**: 使用 `interface{}` 而非泛型(generics)
|
||||
- **没有 ok 检查的类型断言**: 可能导致 panic
|
||||
```go
|
||||
// Bad
|
||||
// 错误示例 (Bad)
|
||||
v := x.(string)
|
||||
// Good
|
||||
// 正确示例 (Good)
|
||||
v, ok := x.(string)
|
||||
if !ok { return ErrInvalidType }
|
||||
```
|
||||
|
||||
- **Deferred Call in Loop**: Resource accumulation
|
||||
- **循环中的延迟调用 (defer)**: 导致资源堆积
|
||||
```go
|
||||
// Bad: Files opened until function returns
|
||||
// 错误示例 (Bad): 文件直到函数返回才会被关闭
|
||||
for _, path := range paths {
|
||||
f, _ := os.Open(path)
|
||||
defer f.Close()
|
||||
}
|
||||
// Good: Close in loop iteration
|

// 正确示例 (Good): 在循环迭代中关闭

|
||||
- **Warning**: MEDIUM issues only (can merge with caution)
|
||||
- **Block**: CRITICAL or HIGH issues found
|
||||
- **批准 (Approve)**: 无“严重 (CRITICAL)”或“高危 (HIGH)”问题
|
||||
- **警告 (Warning)**: 仅包含“中等 (MEDIUM)”问题(可谨慎合并)

|
||||
## Go Version Considerations
|
||||
## Go 版本考虑因素
|
||||
|
||||
- Check `go.mod` for minimum Go version
|
||||
- Note if code uses features from newer Go versions (generics 1.18+, fuzzing 1.18+)
|
||||
- Flag deprecated functions from standard library
|
||||
- 检查 `go.mod` 以确认最低 Go 版本要求
|
||||
- 注意代码是否使用了较新版本的特性(如 1.18+ 的泛型、1.18+ 的模糊测试)
|
||||
- 标记标准库中已弃用的函数
|
||||
|
||||
Review with the mindset: "Would this code pass review at Google or a top Go shop?"
|
||||
审查时请思考:“这段代码能否通过 Google 或顶级 Go 团队的审查?”
