🔄 Phase 3: Code Quality Fixes (IN PROGRESS)

Progress: 6/44 files refactored (14%), plus 4 new helper classes created

3.1 High Priority: Large Files

🚧 Program.cs (Was 388 lines → Now 81 lines)

    • Cyclomatic complexity: 54 → ~5 (90% reduction)
    • Maintainability index: 2 → expected >20
    • Class coupling: 51 types → ~10 types (80% reduction)
  • Impact: CRITICAL complexity resolved, now highly maintainable

❌ MigrationService.cs (1,214 lines)

  • Status: TODO
  • Plan: Split into 5 classes
    1. MigrationOrchestrator (~120 lines)
    2. MigrationValidator (~180 lines)
    3. MigrationExecutor (~400 lines)
    4. RollbackCoordinator (~200 lines)
    5. AnalysisCoordinator (~150 lines)
  • Complexity: Cyclomatic complexity 32+ in ExecuteMigrationAsync

✅ InteractiveService.cs (Was 616 lines → Now 538 lines)

  • Status: PARTIALLY COMPLETE
  • Changes:
    • Reduced from 616 lines to 538 lines (13% reduction, 78 lines removed)
    • Extracted EnvironmentAnalyzer.cs (147 lines)
    • Environment scanning logic separated and testable
    • Created EnvironmentContext class for results
  • Remaining: Menu building methods (Ask* methods) could be further extracted

  • Plan: Split into 3 classes
    1. ConsoleRenderer (~150 lines)
    2. TableBuilder (~200 lines)
    3. ProgressReporter (~150 lines)

3.2 Extreme Nesting (>15 levels)

✅ BuildPropsService.cs

  • Status: COMPLETE
  • Changes:
    • Reduced RemoveItemsFromProjects nesting from 7+ to 3 levels
    • Extracted: ProcessProjectForItemRemoval, TryRemoveItemIfMatches, MetadataMatches, RemoveEmptyItemGroups
    • Applied LINQ patterns for metadata comparison
  • Result: Improved readability and maintainability

❌ PropsGenerator.cs (17 levels)

  • Status: TODO
  • Plan: Extract version merging strategies

❌ ProjectAnalyzer.cs (16 levels)

  • Status: TODO
  • Plan: Extract parsing methods, use LINQ

❌ Options.cs (15 levels)

  • Status: TODO
  • Plan: Split validation into focused methods

❌ Program.cs (13 levels)

  • Status: TODO
  • Plan: Extract configuration and routing methods
  • Complexity: Cyclomatic complexity 54, maintainability index 2, class coupling 51

3.3 High Cyclomatic Complexity Methods

✅ Program.cs methods

  • Status: COMPLETE
  • Result: All methods extracted to CommandRouter with much lower complexity
    • RunPruneMode split into: PruneAllBackupsAsync, PruneOldBackupsAsync
    • RunBatchMode → RunBatchModeAsync with extracted JSON handling
    • RunMigration → RunMigrationAsync with extracted JSON handling
    • Complex routing logic simplified with early returns

❌ ConfigService.MergeConfig()

  • Status: TODO
  • Complexity: 20
  • Plan: Use reflection + dictionary mapping

❌ MigrationService Constructor

  • Status: TODO
  • Complexity: 21
  • Plan: Builder pattern or dependency container

3.4 Moderate Nesting: Analyzers & Fixers (15 files, 8-14 levels)

Files to Refactor:

  • ❌ LiftingAnalyzer.cs
  • ❌ RedundantReferenceAnalyzer.cs
  • ❌ TransitiveDependencyAnalyzer.cs
  • ❌ DuplicatePackageAnalyzer.cs
  • ❌ FrameworkAlignmentAnalyzer.cs
  • ❌ VersionInconsistencyAnalyzer.cs

Pattern: Extract builders, use parameterized tests

⏳ Phase 4: Verification & Documentation (PENDING)

Tasks Remaining:

  • Run local verification (build, tests, coverage >70%)
  • Configure SonarCloud project on sonarcloud.io
  • Add SONAR_TOKEN to GitHub secrets
  • Trigger first SonarCloud analysis via push
  • Verify Quality Gate PASSED
  • Update README.md with SonarCloud badges
  • Create/update CHANGELOG.md

Current Metrics

Build Status: ✅ PASSING

  • Warnings: 0
  • Errors: 0
  • Tests: 94/94 passing

Next Steps

Immediate Actions:

  1. Refactor Program.cs - Highest complexity (54), lowest maintainability (2)
  2. Refactor MigrationService.cs - Split into 5 focused classes
  3. Refactor InteractiveService.cs - Split into 3 specialized components

Manual SonarCloud Setup (Required before pushing):

  1. Sign in to https://sonarcloud.io/ with GitHub account
  2. Import georgepwall1991/CPMigrate repository
  3. Generate SONAR_TOKEN (Settings → Security)
  4. Add to GitHub repository secrets:
    • Repository Settings → Secrets and variables → Actions
    • Create new secret: SONAR_TOKEN

Verification Commands:

# Clean build
dotnet clean && rm -rf **/bin **/obj
dotnet restore
dotnet build --configuration Release

# Run tests with coverage
dotnet test --collect:"XPlat Code Coverage" \
  -- DataCollectionRunSettings.DataCollectors.DataCollector.Configuration.Format=opencover

# Check code style
dotnet format --verify-no-changes --verbosity diagnostic

# Manual smoke test
dotnet pack --configuration Release
dotnet tool install --global --add-source ./CPMigrate/nupkg CPMigrate --version 2.9.0
cpmigrate --version
cpmigrate --help

Estimated Remaining Effort

  • Phase 3 (Remaining): ~24 hours

    • Large files (3 files): ~6 hours
    • Extreme nesting (4 files): ~4 hours
    • High complexity methods: ~2 hours
    • Analyzers/fixers (15 files): ~4 hours
