Handoff: ContentService Phase 0 Task 7 - Benchmark File (32/33 complete)

Task(s)

Executing Task 7 of Phase 0 ContentService refactoring using Subagent-Driven Development workflow.

Task 7 Goal: Create ContentServiceRefactoringBenchmarks.cs with 33 performance benchmarks.

Status: 32 of 33 benchmarks implemented, build passing. Only B33 (Benchmark_BaselineComparison) and commit remain.

Subtask	Description	Status
B1	File skeleton + Benchmark_Save_SingleItem	✅ Completed
B2	Benchmark_Save_BatchOf100	✅ Completed
B3-B7	Remaining CRUD benchmarks (5)	✅ Completed
B8-B13	Query benchmarks (6)	✅ Completed
B14-B20	Publish benchmarks (7)	✅ Completed
B21-B28	Move benchmarks (8)	✅ Completed
B29-B32	Version benchmarks (4)	✅ Completed
B33	Benchmark_BaselineComparison + commit	🔲 NEXT

Implementation Plan: docs/plans/2025-12-20-contentservice-refactor-phase0-implementation.md (Task 7 is lines 1231-2386)

Critical References

1. Implementation Plan: docs/plans/2025-12-20-contentservice-refactor-phase0-implementation.md - Contains exact code for all benchmarks
2. Previous Handoff: thoughts/shared/handoffs/general/2025-12-20_18-58-13_contentservice-phase0-subagent-driven-task7.md - Context from prior session

Recent changes

• Created new file: tests/Umbraco.Tests.Integration/Umbraco.Infrastructure/Services/ContentServiceRefactoringBenchmarks.cs
  • 32 benchmarks implemented across 5 regions (CRUD, Query, Publish, Move, Version)
  • Baseline Comparison region has placeholder for B33

Important Fix Applied: Removed redundant ContentTypeService property (line 50) that was shadowing the base class property. The spec had this error; code quality reviewer caught it.

Learnings

1. Property Shadowing Issue: The implementation plan spec included private IContentTypeService ContentTypeService => GetRequiredService<IContentTypeService>(); but this shadows the same property already available from base class UmbracoIntegrationTestWithContent. The code quality reviewer caught this. The line was removed.

2. Warmup Patterns (v1.2):

   • Mutation operations (Save, Publish, Move, Copy): Manual warmup with throwaway data, then fresh data for measurement
   • Read-only operations (GetById, GetVersions, etc.): Use MeasureAndRecord() with default warmup
   • Destructive operations (Delete, EmptyRecycleBin): Use MeasureAndRecord(skipWarmup: true)

3. Batch Efficiency: Breaking Task 7 into 33 individual steps was reorganized into region-based batches (B1, B2, B3-B7, B8-B13, etc.) for efficiency while maintaining granular tracking.

Artifacts

• tests/Umbraco.Tests.Integration/Umbraco.Infrastructure/Services/ContentServiceRefactoringBenchmarks.cs - UNCOMMITTED benchmark file with 32/33 benchmarks
• docs/plans/2025-12-20-contentservice-refactor-phase0-implementation.md - Implementation plan (lines 1231-2386 for Task 7)

Action Items & Next Steps

1. Complete B33: Add Benchmark_BaselineComparison

   • Find the #region Baseline Comparison (1 test) region (currently empty)
   • Add the Benchmark_BaselineComparison method (spec in plan lines 2299-2355)
   • This is a meta-benchmark that runs a composite sequence (save, publish, query, trash, empty)

2. Verify Build:

   dotnet build tests/Umbraco.Tests.Integration --no-restore -v q
   

3. Commit the file:

   git add tests/Umbraco.Tests.Integration/Umbraco.Infrastructure/Services/ContentServiceRefactoringBenchmarks.cs
   git commit -m "$(cat <<'EOF'
   test: add ContentServiceRefactoringBenchmarks for Phase 0 baseline
   
   Adds 33 performance benchmarks organized by operation type:
   - 7 CRUD operation benchmarks
   - 6 query operation benchmarks
   - 7 publish operation benchmarks
   - 8 move operation benchmarks
   - 4 version operation benchmarks
   - 1 baseline comparison meta-benchmark
   
   Benchmarks output JSON for automated comparison between phases.

4. After Task 7, continue with Tasks 8-11:

   • Task 8: Create ContentServiceBaseTests.cs (unit tests skeleton)
   • Task 9: Run all tests and verify
   • Task 10: Capture baseline benchmarks
   • Task 11: Final verification and summary

Other Notes

• The file currently has 32 benchmarks verified by: grep -c "public void Benchmark_" <file> returns 32
• All benchmarks follow standardized item counts (10/100/1000 pattern per v1.2)
• Pre-existing build warnings in the codebase are unrelated to this work
• The benchmark file extends ContentServiceBenchmarkBase which provides ContentService, ContentType, ContentBuilder, RecordBenchmark(), MeasureAndRecord()
