# 정적 분석 도구 통합을 통한 코드 병합 안정화

## 개요
코드 병합 후 정적 분석 도구를 통합하여 코드 품질, 보안, 성능을 자동으로 검증하고 안정화하는 방안입니다.

## 2024-2025 주요 정적 분석 도구

### 다중 언어 지원 도구

#### 1. **ast-grep** (Rust 기반)
- tree-sitter 사용한 AST 기반 코드 검색 및 린팅
- 다중 코어 활용으로 빠른 성능
- 패턴이 일반 코드처럼 보이는 직관적 인터페이스

```bash
# 설치
npm install -g @ast-grep/cli

# 사용 예시
ast-grep --pattern 'console.log($$$)' --lang javascript
ast-grep --pattern 'print($$$)' --lang python
```

#### 2. **Semgrep** (오픈소스)
- 패턴 기반 정적 분석 엔진
- 30+ 언어 지원
- 커스텀 규칙 작성 가능

```yaml
# .semgrep.yml
rules:
  - id: merged-code-validation
    pattern: |
      $X = merge_code($Y, $Z)
      ...
      $X.validate()
    message: "병합된 코드는 반드시 검증되어야 합니다"
    severity: ERROR
```

#### 3. **SonarQube** (엔터프라이즈)
- 코드 품질, 보안, 신뢰성 종합 분석
- SAST 엔진 내장
- CI/CD 파이프라인 통합

### 언어별 전문 도구

#### JavaScript/TypeScript
- **ESLint**: 가장 널리 사용되는 린터
- **TypeScript Compiler**: 타입 검사
- **SMART TS XL**: 2025년 새로운 고급 분석 도구

#### Python
- **Pylint**: 엄격한 코드 품질 검사
- **mypy**: 정적 타입 검사
- **Bandit**: 보안 취약점 검사

#### Rust
- **Clippy**: Rust 공식 린터
- **cargo-audit**: 의존성 보안 검사
- **miri**: undefined behavior 감지

## CodeBridge 정적 분석 통합 아키텍처

```javascript
// static-analysis-integrator.js
class StaticAnalysisIntegrator {
  constructor() {
    this.analyzers = new Map([
      ['javascript', new JavaScriptAnalyzer()],
      ['python', new PythonAnalyzer()],
      ['rust', new RustAnalyzer()],
      ['universal', new UniversalAnalyzer()]
    ]);
    
    this.severityLevels = {
      ERROR: 3,
      WARNING: 2,
      INFO: 1
    };
  }
  
  async analyzeAndStabilize(mergedCode, language, options = {}) {
    const results = {
      syntax: await this.syntaxAnalysis(mergedCode, language),
      semantic: await this.semanticAnalysis(mergedCode, language),
      security: await this.securityAnalysis(mergedCode, language),
      performance: await this.performanceAnalysis(mergedCode, language),
      style: await this.styleAnalysis(mergedCode, language)
    };
    
    // 자동 수정 적용
    if (options.autoFix) {
      mergedCode = await this.applyAutoFixes(mergedCode, results, language);
    }
    
    // 안정성 점수 계산
    const stabilityScore = this.calculateStabilityScore(results);
    
    return {
      code: mergedCode,
      analysis: results,
      stabilityScore,
      requiresManualReview: this.requiresManualReview(results)
    };
  }
}
```

## 언어별 정적 분석 전략

### JavaScript/TypeScript 분석 파이프라인

```javascript
class JavaScriptAnalyzer {
  async analyze(code, filePath) {
    const issues = [];
    
    // 1. ESLint 실행
    const eslintResults = await this.runESLint(code, {
      extends: ['eslint:recommended', 'plugin:@typescript-eslint/recommended'],
      rules: {
        'no-unused-vars': 'error',
        'no-unreachable': 'error',
        'consistent-return': 'error'
      }
    });
    
    // 2. TypeScript 컴파일러 검사
    if (filePath.endsWith('.ts') || filePath.endsWith('.tsx')) {
      const tscResults = await this.runTypeScriptCompiler(code, {
        strict: true,
        noImplicitAny: true,
        strictNullChecks: true
      });
    }
    
    // 3. 보안 검사 (Semgrep)
    const securityResults = await this.runSemgrep(code, {
      config: 'auto',
      severity: ['ERROR', 'WARNING']
    });
    
    // 4. 복잡도 분석
    const complexityResults = this.analyzeComplexity(code);
    
    return this.consolidateResults(issues);
  }
  
  async applyAutoFixes(code, issues) {
    // ESLint 자동 수정
    const eslint = new ESLint({ fix: true });
    const results = await eslint.lintText(code);
    
    if (results[0].output) {
      code = results[0].output;
    }
    
    return code;
  }
}
```

### Python 분석 파이프라인

```python
class PythonAnalyzer:
    def analyze(self, code: str, file_path: str) -> List[Issue]:
        issues = []
        
        # 1. 문법 검사 (ast 모듈)
        try:
            ast.parse(code)
        except SyntaxError as e:
            issues.append(Issue('syntax', str(e), severity='ERROR'))
        
        # 2. Pylint 실행
        pylint_results = self.run_pylint(code, {
            'disable': ['too-few-public-methods'],
            'max-line-length': 120
        })
        
        # 3. 타입 검사 (mypy)
        if self.has_type_hints(code):
            mypy_results = self.run_mypy(code, {
                'strict': True,
                'warn_return_any': True
            })
        
        # 4. 보안 검사 (Bandit)
        security_results = self.run_bandit(code, {
            'severity': ['MEDIUM', 'HIGH']
        })
        
        # 5. 코드 복잡도 (radon)
        complexity_results = self.analyze_complexity(code)
        
        return self.consolidate_results(issues)
    
    def apply_auto_fixes(self, code: str, issues: List[Issue]) -> str:
        # autopep8 자동 포맷팅
        import autopep8
        code = autopep8.fix_code(code, options={'aggressive': 1})
        
        # isort import 정렬
        import isort
        code = isort.code(code)
        
        return code
```

### Rust 분석 파이프라인

```rust
struct RustAnalyzer;

impl RustAnalyzer {
    async fn analyze(&self, code: &str, file_path: &str) -> Vec<Issue> {
        let mut issues = vec![];
        
        // 1. rustc 컴파일 검사
        let compile_results = self.run_rustc(code, &[
            "--edition=2021",
            "--cap-lints=warn"
        ]).await?;
        
        // 2. Clippy 린트
        let clippy_results = self.run_clippy(code, &[
            "-W", "clippy::all",
            "-W", "clippy::pedantic",
            "-A", "clippy::module_name_repetitions"
        ]).await?;
        
        // 3. 보안 감사 (cargo-audit)
        let security_results = self.run_cargo_audit(file_path).await?;
        
        // 4. unsafe 코드 분석
        let unsafe_results = self.analyze_unsafe_usage(code);
        
        // 5. 메모리 안전성 (miri)
        if self.has_tests(code) {
            let miri_results = self.run_miri(code).await?;
        }
        
        self.consolidate_results(issues)
    }
    
    fn apply_auto_fixes(&self, code: &str, issues: &[Issue]) -> String {
        // rustfmt 자동 포맷팅
        let formatted = rustfmt::format_code(code);
        
        // Clippy 제안 자동 적용
        let fixed = self.apply_clippy_suggestions(formatted, issues);
        
        fixed
    }
}
```

## 통합 검증 워크플로우

```javascript
class CodeBridgeValidator {
  async validateMergedCode(originalCode, snippetCode, mergedCode, language) {
    const validation = {
      preChecks: await this.preValidation(snippetCode, language),
      mergeValidation: await this.validateMerge(originalCode, mergedCode, language),
      postChecks: await this.postValidation(mergedCode, language),
      crossValidation: await this.crossLanguageValidation(mergedCode, language)
    };
    
    return {
      isValid: this.allChecksPassed(validation),
      report: this.generateValidationReport(validation),
      suggestions: this.generateImprovementSuggestions(validation)
    };
  }
  
  async preValidation(code, language) {
    // 병합 전 스니펫 검증
    return {
      syntaxValid: await this.checkSyntax(code, language),
      noMaliciousCode: await this.scanForMaliciousPatterns(code),
      compatibleVersion: await this.checkLanguageVersion(code, language)
    };
  }
  
  async validateMerge(original, merged, language) {
    // 병합 결과 검증
    return {
      preservesOriginalBehavior: await this.compareBehavior(original, merged),
      noConflicts: await this.checkForConflicts(merged),
      maintainsTypes: await this.validateTypeConsistency(original, merged)
    };
  }
  
  async postValidation(code, language) {
    // 병합 후 종합 검증
    const analyzer = new StaticAnalysisIntegrator();
    const results = await analyzer.analyzeAndStabilize(code, language, {
      autoFix: true
    });
    
    return {
      stabilityScore: results.stabilityScore,
      criticalIssues: results.analysis.filter(i => i.severity === 'ERROR'),
      performanceImpact: await this.assessPerformanceImpact(code)
    };
  }
}
```

## 안정성 점수 계산

```javascript
class StabilityScoreCalculator {
  calculate(analysisResults) {
    const weights = {
      syntax: 0.3,      // 문법 정확성
      semantic: 0.25,   // 의미론적 정확성
      security: 0.2,    // 보안 취약점
      performance: 0.15, // 성능 문제
      style: 0.1        // 코드 스타일
    };
    
    let totalScore = 0;
    
    for (const [category, weight] of Object.entries(weights)) {
      const categoryResults = analysisResults[category];
      const categoryScore = this.calculateCategoryScore(categoryResults);
      totalScore += categoryScore * weight;
    }
    
    return {
      score: totalScore,
      grade: this.getGrade(totalScore),
      breakdown: this.getBreakdown(analysisResults)
    };
  }
  
  calculateCategoryScore(results) {
    const errorCount = results.filter(r => r.severity === 'ERROR').length;
    const warningCount = results.filter(r => r.severity === 'WARNING').length;
    
    // 오류가 없으면 100점, 오류마다 감점
    let score = 100;
    score -= errorCount * 20;
    score -= warningCount * 5;
    
    return Math.max(0, score);
  }
  
  getGrade(score) {
    if (score >= 90) return 'A';
    if (score >= 80) return 'B';
    if (score >= 70) return 'C';
    if (score >= 60) return 'D';
    return 'F';
  }
}
```
