Golang求助：如何解决我的Github问题 - Sanjeev Mansotra

在大型GitHub协作项目中，管理代码审查和CI工作流需要结合自动化工具和明确的流程规范。以下是具体实现方案：

1. 代码审查自动化配置

使用GitHub的Protected Branches和Required Reviews：

// 示例：通过GitHub API设置保护分支规则
package main

import (
    "context"
    "fmt"
    "github.com/google/go-github/v50/github"
    "golang.org/x/oauth2"
)

func configureBranchProtection(client *github.Client, owner, repo, branch string) {
    protection := &github.ProtectionRequest{
        RequiredPullRequestReviews: &github.PullRequestReviewsEnforcementRequest{
            RequiredApprovingReviewCount: 2, // 至少2个批准
            DismissStaleReviews:          true,
            RequireCodeOwnerReviews:      true,
        },
        RequireStatusChecks: &github.RequiredStatusChecks{
            Strict:   true, // 要求分支为最新
            Contexts: []string{"ci/go-test", "ci/lint", "ci/coverage"},
        },
        EnforceAdmins: false,
    }
    
    _, _, err := client.Repositories.UpdateBranchProtection(
        context.Background(),
        owner,
        repo,
        branch,
        protection,
    )
    if err != nil {
        panic(err)
    }
}

2. GitHub Actions CI/CD工作流

创建 .github/workflows/ci.yml：

name: CI Pipeline

on:
  pull_request:
    branches: [ main, develop ]
  push:
    branches: [ main ]

jobs:
  test:
    runs-on: ubuntu-latest
    steps:
    - uses: actions/checkout@v3
    
    - name: Setup Go
      uses: actions/setup-go@v3
      with:
        go-version: '1.20'
    
    - name: Run tests with coverage
      run: |
        go test ./... -v -coverprofile=coverage.out
        go tool cover -func=coverage.out
    
    - name: Upload coverage
      uses: codecov/codecov-action@v3
      with:
        file: ./coverage.out

  lint:
    runs-on: ubuntu-latest
    steps:
    - uses: actions/checkout@v3
    
    - name: golangci-lint
      uses: golangci/golangci-lint-action@v3
      with:
        version: v1.52
        
  check-conflicts:
    runs-on: ubuntu-latest
    steps:
    - uses: actions/checkout@v3
      with:
        fetch-depth: 0
    
    - name: Check merge conflicts
      run: |
        git fetch origin main
        git merge-base HEAD origin/main
        git merge-tree `git merge-base HEAD origin/main` HEAD origin/main | 
          grep -A3 -B3 "<<<<<<<"
        
  auto-merge:
    needs: [test, lint, check-conflicts]
    if: github.event_name == 'pull_request' && github.event.pull_request.merged == false
    runs-on: ubuntu-latest
    steps:
    - uses: actions/checkout@v3
      with:
        ref: ${{ github.event.pull_request.head.ref }}
    
    - name: Auto-merge PR
      uses: pascalgn/automerge-action@v0.15.5
      env:
        GITHUB_TOKEN: ${{ secrets.GITHUB_TOKEN }}
        MERGE_LABELS: "automerge"
        MERGE_METHOD: "squash"

3. 冲突检测与解决自动化

创建冲突检查工具：

// cmd/conflict-check/main.go
package main

import (
    "bufio"
    "fmt"
    "os"
    "os/exec"
    "strings"
)

func checkMergeConflicts(baseBranch, featureBranch string) (bool, []string) {
    cmd := exec.Command("git", "merge-tree", baseBranch, featureBranch)
    output, err := cmd.Output()
    if err != nil {
        return false, nil
    }
    
    scanner := bufio.NewScanner(strings.NewReader(string(output)))
    var conflicts []string
    inConflict := false
    var conflictBuffer strings.Builder
    
    for scanner.Scan() {
        line := scanner.Text()
        if strings.Contains(line, "<<<<<<<") {
            inConflict = true
            conflictBuffer.Reset()
        }
        
        if inConflict {
            conflictBuffer.WriteString(line + "\n")
        }
        
        if strings.Contains(line, ">>>>>>>") {
            inConflict = false
            conflicts = append(conflicts, conflictBuffer.String())
        }
    }
    
    return len(conflicts) > 0, conflicts
}

func autoResolveSimpleConflicts(filepath string) error {
    content, err := os.ReadFile(filepath)
    if err != nil {
        return err
    }
    
    lines := strings.Split(string(content), "\n")
    var resolved []string
    skip := false
    
    for _, line := range lines {
        if strings.Contains(line, "<<<<<<<") {
            skip = true
            continue
        }
        if strings.Contains(line, "=======") {
            continue
        }
        if strings.Contains(line, ">>>>>>>") {
            skip = false
            continue
        }
        if !skip {
            resolved = append(resolved, line)
        }
    }
    
    return os.WriteFile(filepath, []byte(strings.Join(resolved, "\n")), 0644)
}

4. 代码质量门禁

创建预提交钩子和质量检查：

// tools/quality-gate/main.go
package main

import (
    "fmt"
    "os"
    "os/exec"
    "path/filepath"
)

type QualityGate struct {
    MinCoverage    float64
    MaxComplexity  int
    RequireLintPass bool
}

func (qg *QualityGate) Check() bool {
    allPassed := true
    
    // 检查测试覆盖率
    if coverage := getTestCoverage(); coverage < qg.MinCoverage {
        fmt.Printf("❌ 测试覆盖率不足: %.2f%% < %.2f%%\n", coverage, qg.MinCoverage)
        allPassed = false
    }
    
    // 运行golangci-lint
    if qg.RequireLintPass {
        if err := runLint(); err != nil {
            fmt.Println("❌ 代码规范检查失败")
            allPassed = false
        }
    }
    
    // 检查循环复杂度
    if complexity := checkCyclomaticComplexity(); complexity > qg.MaxComplexity {
        fmt.Printf("❌ 循环复杂度过高: %d > %d\n", complexity, qg.MaxComplexity)
        allPassed = false
    }
    
    return allPassed
}

func getTestCoverage() float64 {
    cmd := exec.Command("go", "test", "./...", "-coverprofile=coverage.out")
    cmd.Run()
    
    cmd = exec.Command("go", "tool", "cover", "-func=coverage.out")
    output, _ := cmd.Output()
    
    // 解析覆盖率输出
    var coverage float64
    // 解析逻辑...
    return coverage
}

// 预提交钩子示例
func installPreCommitHook() error {
    hookContent := `#!/bin/sh
go run ./tools/quality-gate
if [ $? -ne 0 ]; then
    echo "质量门禁检查失败，提交中止"
    exit 1
fi`
    
    hookPath := filepath.Join(".git", "hooks", "pre-commit")
    return os.WriteFile(hookPath, []byte(hookContent), 0755)
}

5. 分支策略配置

// pkg/branch/strategy.go
package branch

import (
    "strings"
    "time"
)

type BranchStrategy struct {
    NamingPattern   string
    MaxLifeDays     int
    AutoStaleCheck  bool
    RequiredPrefix  string
}

func (bs *BranchStrategy) ValidateBranchName(name string) bool {
    if bs.RequiredPrefix != "" && !strings.HasPrefix(name, bs.RequiredPrefix) {
        return false
    }
    
    patterns := map[string]string{
        "feature":  `^feature/[a-z0-9-]+$`,
        "bugfix":   `^bugfix/[a-z0-9-]+$`,
        "hotfix":   `^hotfix/[a-z0-9-]+$`,
        "release":  `^release/v[0-9]+\.[0-9]+$`,
    }
    
    // 验证分支名模式
    return true
}

func (bs *BranchStrategy) CheckStaleBranches(branches []string, createdDate map[string]time.Time) []string {
    var stale []string
    cutoff := time.Now().AddDate(0, 0, -bs.MaxLifeDays)
    
    for _, branch := range branches {
        if created, exists := createdDate[branch]; exists && created.Before(cutoff) {
            stale = append(stale, branch)
        }
    }
    return stale
}

这些实现提供了完整的自动化工作流：通过GitHub Actions实现CI/CD流水线，通过质量门禁确保代码标准，通过冲突检测减少合并问题。关键是在.github目录中配置正确的工作流文件，并结合团队约定的分支策略。
