# Handoff: Utf8ToAsciiConverter Refactoring Analysis
## Task(s)
**Completed:**
1. Cyclomatic complexity comparison between original and refactored implementation
2. Test count comparison before and after refactoring
## Critical References
- `src/Umbraco.Core/Strings/Utf8ToAsciiConverter.cs` - New SIMD-optimized implementation
- `src/Umbraco.Core/Strings/Utf8ToAsciiConverterOriginal.cs` - Original implementation (disabled with `#if false`)
- `tests/Umbraco.Tests.UnitTests/Umbraco.Core/Strings/TestData/golden-mappings.json` - 1,308 character mappings for regression testing
## Recent changes
No code changes made in this session - analysis only.
## Learnings
### Cyclomatic Complexity Reduction
- **Original**: ~287 total complexity (dominated by ~280 in single switch statement with 276 case groups)
- **New**: 25 total complexity (distributed across 4 focused methods)
- **Reduction**: 91% overall, 97% for maximum method complexity
### Architectural Changes
1. **Switch Statement → Dictionary Lookup**: 3,400-line switch replaced by `FrozenDictionary<char, string>` loaded from JSON
2. **Unicode Normalization**: ~180 case groups eliminated by using `NormalizationForm.FormD` for accented Latin characters
3. **SIMD Fast Path**: Uses `SearchValues<char>` for vectorized ASCII detection
4. **Separation of Concerns**: Logic split into `Convert()`, `ProcessNonAscii()`, `TryNormalize()`
### Test Coverage Added
- **Before**: 0 dedicated tests existed
- **After**: 2,649 test cases across 4 test files
- Golden file testing validates all 1,308 character mappings from original implementation
## Artifacts
Analysis results documented in conversation - no files created.
Key files analyzed:
- `src/Umbraco.Core/Strings/Utf8ToAsciiConverter.cs:1-209` - New implementation (~210 LOC)
- `src/Umbraco.Core/Strings/Utf8ToAsciiConverterOriginal.cs:1-3633` - Original implementation (~3,600 LOC)
- `tests/Umbraco.Tests.UnitTests/Umbraco.Core/Strings/Utf8ToAsciiConverterTests.cs` - 30 test cases
- `tests/Umbraco.Tests.UnitTests/Umbraco.Core/Strings/Utf8ToAsciiConverterGoldenTests.cs` - 2,616 test cases
- `tests/Umbraco.Tests.UnitTests/Umbraco.Core/Strings/Utf8ToAsciiConverterInterfaceTests.cs` - 2 tests
- `tests/Umbraco.Tests.UnitTests/Umbraco.Core/Strings/Utf8ToAsciiConverterNormalizationCoverageTests.cs` - 1 analysis test
## Action Items & Next Steps
The refactoring analysis is complete. Potential follow-up:
1. Review benchmark results in `docs/benchmarks/utf8-converter-final-2025-11-27.md`
2. Consider merging branch to main if all tests pass
3. Document normalization coverage findings from `Utf8ToAsciiConverterNormalizationCoverageTests`
## Other Notes
### Key Metrics Summary
| Metric | Before | After | Change |
|--------|--------|-------|--------|
| Cyclomatic Complexity | ~287 | 25 | -91% |
| Lines of Code | ~3,600 | ~210 | -94% |
| Switch Cases | 276 | 0 | -100% |
| Test Cases | 0 | 2,649 | +2,649 |
### Branch Status
The branch `refactor/Utf8ToAsciiConverter` contains 16 commits implementing the SIMD-optimized converter with:
- Interface abstraction (`IUtf8ToAsciiConverter`)
- DI integration via `ICharacterMappingLoader`
- Static wrapper for backwards compatibility (`Utf8ToAsciiConverterStatic`)
- Comprehensive test suite with golden file validation

# Handoff: ContentService Refactoring Design Review
## Task(s)
| Task | Status |
|------|--------|
| Review design document for major issues | Completed |
| Identify architecture/codebase mismatches | Completed |
| Make decisions on 9 major issues | Completed |
| Revise design document with corrections | Completed |
| Commit updated design | Completed |
The session focused on critically reviewing `docs/plans/2025-12-04-contentservice-refactoring-design.md` and identifying major issues where the design conflicted with the actual codebase structure.
## Critical References
- `docs/plans/2025-12-04-contentservice-refactoring-design.md` - The revised design document (primary artifact)
- `src/Umbraco.Core/Services/ContentService.cs` - The 3,823-line god class being refactored
- `src/Umbraco.Core/CLAUDE.md` - Core architecture guide with patterns
## Recent Changes
- `docs/plans/2025-12-04-contentservice-refactoring-design.md` - Complete revision addressing 9 major issues
## Learnings
### Critical Architecture Discovery
The original design assumed implementations go in `Umbraco.Infrastructure`, but the actual codebase has:
- `ContentService.cs` in `Umbraco.Core/Services/` (not Infrastructure)
- `ContentEditingService.cs` in `Umbraco.Core/Services/`
- `ContentPublishingService.cs` in `Umbraco.Core/Services/`
### Existing Service Complexity
`ContentPublishingService` already has:
- Background task handling via `ILongRunningOperationService`
- Schedule management with `ContentScheduleCollection`
- `IUmbracoContextFactory` integration
`ContentEditingService` uses inheritance from `ContentEditingServiceWithSortingBase`, not delegation.
### Return Type Patterns
Three incompatible patterns exist in the codebase:
1. Legacy `OperationResult`/`PublishResult` (IContentService)
2. Modern `Attempt<TResult, TStatus>` (IContentEditingService)
3. Proposed new types (design) - **rejected in favor of reusing existing**
### Pagination Patterns
- Legacy: `pageIndex/pageSize` with `out long totalRecords`
- Modern: `PagedModel<T>` containing items and total
- Design should use `PagedModel<T>` for new services
## Artifacts
Primary artifact produced:
- `docs/plans/2025-12-04-contentservice-refactoring-design.md` - Revised design document
Key sections added/updated:
- Lines 22-36: Design Decisions Log (new section documenting all 8 decisions)
- Lines 39-123: Revised Architecture section with corrected layer structure
- Lines 203-253: Updated `IContentQueryService` with `PagedModel<T>` and complete method list
- Lines 255-338: Simplified pipeline components using existing types
- Lines 342-389: Corrected file locations (all in Umbraco.Core)
## Action Items & Next Steps
1. **Begin Phase 1 Implementation** - Introduce pipeline components:
- Create `IPublishingValidator`, `IPublishingExecutor`, `IPublishingStrategy`, `IPublishingNotifier`
- Location: `src/Umbraco.Core/Services/Publishing/`
- Components only depend on repositories (one-way dependencies)
2. **Create Phase 1 Implementation Plan** - Run `/superpowers:write-plan` to generate detailed task breakdown for Phase 1
3. **Set Up Benchmarks** - Create `tests/Umbraco.Tests.Benchmarks/ContentPublishingBenchmarks.cs` to establish baseline before changes
4. **Integration with ContentPublishingService** - Modify `ContentPublishingService` to use new components internally while keeping public API unchanged
## Other Notes
### Key Design Decisions Made
| # | Issue | Decision |
|---|-------|----------|
| 1 | Architecture | Implementations in `Umbraco.Core` (match existing) |
| 2 | Service relationships | Gradual extraction - components are helpers |
| 3 | Dependencies | One-way only - components depend on repositories |
| 4 | Async/sync | Query service stays sync |
| 5 | Return types | Reuse existing `PublishResult` |
| 6 | Pagination | Use `PagedModel<T>` |
| 7 | DI registration | Add to existing `UmbracoBuilder.Services.cs` |
| 8 | Query capabilities | Pragmatic split |
### Removed from Original Design
- `IContentMutationService` - keep in facades
- `IContentTreeService` - keep in facades
- `IContentPublishingPipeline` - use individual components instead
- New status enums - reuse existing types
### Important File Locations
- Existing services: `src/Umbraco.Core/Services/`
- DI registration: `src/Umbraco.Infrastructure/DependencyInjection/UmbracoBuilder.Services.cs`
- Test location: `tests/Umbraco.Tests.UnitTests/Umbraco.Core/Services/`

# Handoff: Phase 1 Publishing Pipeline Implementation
## Task(s)
Implementing Phase 1 of the ContentService publishing pipeline refactoring using **subagent-driven development**.
**Plan Document:** `docs/plans/2025-12-13-phase-1-implementation-fixes.md`
### Task Status (11 total)
| Task | Description | Status |
|------|-------------|--------|
| 1 | Update Phase 1 Design with ICultureImpactFactory Dependency | **Completed** |
| 2 | Document Pipeline Order Decision | **Completed** |
| 3 | Document PublishAction Enum Omission | **Completed** |
| 4 | Update IPublishingStrategy Interface | **Completed** |
| 5 | Implement PublishingStrategy with Repository | **Completed** (code review passed) |
| 6 | Create BatchValidationContext | **Pending** - next up |
| 7 | Implement PublishingValidator with Parallel Processing | Pending |
| 8 | Implement PublishingExecutor with Repository Batch Operations | Pending |
| 9 | Create Integration Tests Comparing Pipeline to Legacy | Pending |
| 10 | Update Benchmark to Use .NET 10.0 | Pending |
| 11 | Add ContentValidationResult with Factory Methods | Pending |
**Current Phase:** Task 6 is next
## Critical References
1. **Implementation Plan:** `docs/plans/2025-12-13-phase-1-implementation-fixes.md` - The detailed implementation plan with code snippets for each task
2. **Design Document:** `docs/plans/2025-12-13-phase-1-publishing-pipeline-design.md` - Phase 1 architectural design
3. **Main Design:** `docs/plans/2025-12-04-contentservice-refactoring-design.md` - Overall ContentService refactoring design
## Recent changes
- `f1401e8dd5`: docs: add ICultureImpactFactory to Phase 1 validator dependencies
- `b7045649c9`: docs: document pipeline order difference for branch publishing
- `ca448fd7c2`: docs: document PublishAction enum omission in Phase 1
- `a7b5f1d043`: feat(core): add IPublishingStrategy interface
- `4fc6c009da`: test(perf): add PublishBranch performance baseline tests
- `41ecbd1bc1`: feat(core): implement PublishingStrategy with IDocumentRepository
## Learnings
1. **Implementation goes in Infrastructure, not Core**: The plan specified implementation in `Umbraco.Core`, but `ISqlContext` dependency requires implementation in `Umbraco.Infrastructure`. Interface stays in Core, implementation goes to Infrastructure.
2. **InternalsVisibleTo required**: Added `InternalsVisibleTo` for `Umbraco.Infrastructure` in `Umbraco.Core.csproj` so Infrastructure can access internal types like `PublishingPlan`.
3. **Baseline performance established**: Legacy `PublishBranch` performance at 50 items = **62.7 items/sec**. Target is 2x = **125+ items/sec**.
4. **Test mocking pattern**: For `VariesByCulture()` extension method, mock the underlying `Variations` property on `ISimpleContentType`, not the extension method directly.
5. **ContentType creation in tests**: Don't use `ContentTypeBuilder`. Use direct instantiation: `new ContentType(ShortStringHelper, -1) { Alias = "...", Name = "...", Variations = ContentVariation.Nothing }`
## Artifacts
**Created/Modified Files:**
- `docs/plans/2025-12-13-phase-1-publishing-pipeline-design.md:87` - Added ICultureImpactFactory dependency
- `docs/plans/2025-12-13-phase-1-publishing-pipeline-design.md:168` - Added PublishAction omission note
- `docs/plans/2025-12-04-contentservice-refactoring-design.md:36` - Added decision #10 for pipeline order
- `docs/plans/2025-12-04-contentservice-refactoring-design.md:131-152` - Updated Component Flow section
- `docs/plans/2025-12-14-phase-1-baseline-performance.md` - Performance baseline document
- `src/Umbraco.Core/Services/Publishing/IPublishingStrategy.cs` - Interface (27 lines)
- `src/Umbraco.Infrastructure/Services/Publishing/PublishingStrategy.cs` - Implementation (238 lines)
- `src/Umbraco.Core/Umbraco.Core.csproj` - Added InternalsVisibleTo
- `tests/Umbraco.Tests.UnitTests/Umbraco.Core/Services/Publishing/PublishingStrategyTests.cs` - Unit tests (159 lines)
- `tests/Umbraco.Tests.Integration/Umbraco.Infrastructure/Services/ContentServicePublishBranchPerformanceTests.cs` - Performance tests (121 lines)
## Action Items & Next Steps
1. **Resume from Task 6**: Read the plan at `docs/plans/2025-12-13-phase-1-implementation-fixes.md` and continue with Task 6 (Create BatchValidationContext)
2. **Follow TDD pattern**: For each task, write failing test first, then implementation, then verify tests pass, then commit
3. **Use code review after implementation tasks**: After Tasks 6, 7, 8 (the main implementation tasks), dispatch a code-reviewer subagent
4. **Run performance tests after all tasks**: Compare against baseline (62.7 items/sec target: 125+ items/sec)
5. **Remaining tasks (6-11)**:
- Task 6: Create `BatchValidationContext` record
- Task 7: Implement `PublishingValidator` with parallel processing
- Task 8: Implement `PublishingExecutor` with repository batch operations
- Task 9: Create integration tests comparing pipeline to legacy
- Task 10: Update benchmark to use .NET 10.0
- Task 11: Add `ContentValidationResult` with factory methods
## Other Notes
**Skill in use:** `superpowers:subagent-driven-development` - Dispatches fresh subagent per task with code review between tasks.
**Baseline test command:**
```bash
dotnet test tests/Umbraco.Tests.Integration \
--filter "FullyQualifiedName~ContentServicePublishBranchPerformanceTests" \
-v normal
```
**Existing tests to verify (125 pass):**
- `ContentServicePublishBranchTests`: 20 tests
- `ContentPublishingServiceTests`: 105 tests
**Key directories:**
- Pipeline types: `src/Umbraco.Core/Services/Publishing/`
- Pipeline implementations: `src/Umbraco.Infrastructure/Services/Publishing/`
- Unit tests: `tests/Umbraco.Tests.UnitTests/Umbraco.Core/Services/Publishing/`
- Integration tests: `tests/Umbraco.Tests.Integration/Umbraco.Infrastructure/Services/`

# Handoff: Phase 1 Publishing Pipeline - Plan Merge Analysis
## Task(s)
**Analyzed two overlapping implementation plan documents** to determine how to merge them and assessed current implementation progress.
### Documents Analyzed
1. **Original Plan**: `docs/plans/2025-12-13-phase-1-publishing-pipeline-implementation.md` (17 tasks)
2. **Fixes Plan**: `docs/plans/2025-12-13-phase-1-implementation-fixes.md` (11 tasks)
### Key Finding
The "Fixes Plan" is authoritative - it corrects critical architectural issues in the original:
| Component | Original Plan | Fixes Plan |
|-----------|--------------|------------|
| PublishingStrategy | `IContentService.GetPagedDescendants` | `IDocumentRepository.GetPage` |
| PublishingExecutor | `IContentService.Publish` | `IDocumentRepository.Save` |
| PublishingValidator | Sequential validation | `Parallel.For` + `Environment.ProcessorCount` |
| Benchmark | `RuntimeMoniker.Net90` | `RuntimeMoniker.Net100` |
### Implementation Status (Fixes Plan)
| Task | Description | Status |
|------|-------------|--------|
| 1-3 | Documentation updates (ICultureImpactFactory, pipeline order, PublishAction) | **Completed** |
| 4 | IPublishingStrategy interface | **Completed** |
| 5 | PublishingStrategy with IDocumentRepository | **Completed** (code review passed) |
| 6 | BatchValidationContext | **Completed** |
| 7 | PublishingValidator with parallel processing | **Completed** (code review passed with fixes) |
| 8 | PublishingExecutor with IDocumentRepository | **Pending** |
| 9 | Integration tests | **Pending** |
| 10 | Benchmark RuntimeMoniker fix | **Pending** |
| 11 | ContentValidationResult (already done in Task 7) | **Completed** |
## Critical References
1. **Fixes Plan (Authoritative)**: `docs/plans/2025-12-13-phase-1-implementation-fixes.md`
2. **Original Plan (Supplementary)**: `docs/plans/2025-12-13-phase-1-publishing-pipeline-implementation.md`
3. **Design Document**: `docs/plans/2025-12-04-contentservice-refactoring-design.md`
## Recent changes
The previous handoff (`2025-12-14_02-34-25_phase1-publishing-pipeline.md`) documented commits through Task 5. Since then:
- `411cc4c595`: feat(core): add BatchValidationContext record (Task 6)
- `c33cce455c`: feat(core): implement PublishingValidator with parallel processing (Task 7, amended with fixes)
## Learnings
1. **Fixes Plan supersedes Original Plan**: The original plan had architectural issues (using IContentService instead of IDocumentRepository). Always use the fixes plan.
2. **Missing pieces in Fixes Plan**: The fixes plan doesn't include:
- Supporting types (PublishingOperation, SkippedContent, PublishingPlan) - these already exist from prior work
- DI registration (original Task 14)
- ContentPublishingService integration (original Task 15)
- IPublishingNotifier/PublishingNotifier (original Tasks 9-10)
3. **Infrastructure vs Core**: Components needing `ISqlContext` (PublishingStrategy) must be in `Umbraco.Infrastructure`, not `Umbraco.Core`. This requires `InternalsVisibleTo` in Core.csproj.
4. **BatchValidationContext usage**: The context is built but not fully utilized in PublishingValidator yet - it's infrastructure for future optimization when IPropertyValidationService is refactored.
## Artifacts
**Implementation files created (this session):**
- `src/Umbraco.Core/Services/Publishing/BatchValidationContext.cs`
- `src/Umbraco.Core/Services/Publishing/ContentValidationResult.cs`
- `src/Umbraco.Core/Services/Publishing/IPublishingValidator.cs`
- `src/Umbraco.Core/Services/Publishing/PublishingValidator.cs`
- `tests/Umbraco.Tests.UnitTests/Umbraco.Core/Services/Publishing/BatchValidationContextTests.cs`
- `tests/Umbraco.Tests.UnitTests/Umbraco.Core/Services/Publishing/PublishingValidatorTests.cs`
**Implementation files created (prior sessions):**
- `src/Umbraco.Core/Services/Publishing/IPublishingStrategy.cs`
- `src/Umbraco.Infrastructure/Services/Publishing/PublishingStrategy.cs`
- `tests/Umbraco.Tests.UnitTests/Umbraco.Core/Services/Publishing/PublishingStrategyTests.cs`
- Supporting types: PublishingOperation, SkippedContent, PublishingPlan (locations in `src/Umbraco.Core/Services/Publishing/`)
## Action Items & Next Steps
### Option 1: Continue Fixes Plan Implementation (Remaining Tasks 8-10)
1. **Task 8**: Implement PublishingExecutor with IDocumentRepository.Save
2. **Task 9**: Create integration tests comparing pipeline to legacy
3. **Task 10**: Update benchmark RuntimeMoniker to Net100
### Option 2: Create Merged Plan Document
Combine both plans into a single authoritative document:
- Use fixes plan architecture (repository-based)
- Add missing pieces from original (DI registration, integration)
- Mark completed tasks
### Option 3: Both
Create merged doc AND continue implementation.
### Recommended
**Option 3** - Create the merged plan for documentation clarity, then continue with Task 8 (PublishingExecutor).
## Other Notes
**Key directories:**
- Pipeline types: `src/Umbraco.Core/Services/Publishing/`
- Pipeline implementations: `src/Umbraco.Infrastructure/Services/Publishing/`
- Unit tests: `tests/Umbraco.Tests.UnitTests/Umbraco.Core/Services/Publishing/`
- Integration tests: `tests/Umbraco.Tests.Integration/Umbraco.Infrastructure/Services/`
**Skill in use:** `superpowers:subagent-driven-development` - Dispatches fresh subagent per task with code review between tasks.
**Performance target:** Legacy PublishBranch at 50 items = 62.7 items/sec. Target is 2x = 125+ items/sec.

# Handoff: Phase 1 Publishing Pipeline - Subagent-Driven Development
## Task(s)
Implementing Phase 1 of the publishing pipeline refactoring using the **subagent-driven-development** skill. This creates four internal pipeline components (Strategy, Validator, Executor, Notifier) for branch publishing using repository-based architecture.
**Plan document**: `docs/plans/2025-12-14-phase-1-publishing-pipeline-combined-implementation.md`
### Status Summary
| Task | Description | Status |
|------|-------------|--------|
| Task 1-7 | Supporting types & first interfaces | **COMPLETED** (before session) |
| Task 8 | IPublishingExecutor interface | **COMPLETED** |
| Task 9 | IPublishingNotifier interface | **COMPLETED** |
| Task 10-11 | PublishingStrategy & PublishingValidator implementations | **COMPLETED** (before session) |
| Task 12 | PublishingExecutor with IDocumentRepository | **COMPLETED** |
| Task 13 | PublishingNotifier implementation | **COMPLETED** |
| Task 14 | Register pipeline components in DI | **COMPLETED** |
| Task 15 | Add PerformPublishBranchPipelineAsync method | **COMPLETED** |
| Task 16 | Create integration tests | **COMPLETED** |
| Task 17 | Create benchmark infrastructure | **COMPLETED** |
| Task 18 | Run full test suite | **PENDING** |
**Current Phase**: Task 18 (final verification) - need to run full test suite
## Critical References
1. **Implementation Plan**: `docs/plans/2025-12-14-phase-1-publishing-pipeline-combined-implementation.md`
2. **Core CLAUDE.md**: `src/Umbraco.Core/CLAUDE.md` - defines scoping patterns, notification patterns
3. **superpowers:subagent-driven-development skill** - workflow being followed
## Recent changes
All changes committed to `refactor/ContentService` branch:
- `src/Umbraco.Core/Services/Publishing/IPublishingExecutor.cs` - Added interface (Task 8)
- `src/Umbraco.Core/Services/Publishing/IPublishingNotifier.cs` - Added interface (Task 9)
- `src/Umbraco.Infrastructure/Services/Publishing/PublishingExecutor.cs` - Implementation with IDocumentRepository (Task 12)
- `src/Umbraco.Core/Services/Publishing/PublishingNotifier.cs` - Implementation (Task 13)
- `tests/Umbraco.Tests.UnitTests/Umbraco.Core/Services/Publishing/PublishingExecutorTests.cs` - 4 unit tests
- `tests/Umbraco.Tests.UnitTests/Umbraco.Core/Services/Publishing/PublishingNotifierTests.cs` - 3 unit tests
- `src/Umbraco.Infrastructure/DependencyInjection/UmbracoBuilder.Services.cs:92-96` - DI registration
- `src/Umbraco.Core/Services/ContentPublishingService.cs` - Added pipeline fields, constructor params, and PerformPublishBranchPipelineAsync method
- `tests/Umbraco.Tests.Integration/Umbraco.Infrastructure/Services/Publishing/PublishingPipelineIntegrationTests.cs` - 3 integration tests
- `tests/Umbraco.Tests.Benchmarks/ContentPublishingPipelineBenchmarks.cs` - Benchmark infrastructure
## Learnings
1. **ContentValidationResult naming collision**: There are two types with this name in the codebase:
- `Umbraco.Cms.Core.Models.ContentEditing.ContentValidationResult` (existing)
- `Umbraco.Cms.Core.Services.Publishing.ContentValidationResult` (new pipeline type)
- Fixed by using fully qualified names in `ContentPublishingService.cs:199,251,278`
2. **PublishCulture extension method signature**: The real method requires `PropertyEditorCollection` as a parameter, which wasn't in the plan. Had to add this dependency to `PublishingExecutor`.
3. **RuntimeMoniker for .NET 10**: Use `RuntimeMoniker.Net10_0` (not `Net100` as plan stated)
4. **InternalsVisibleTo already configured**: `Umbraco.Core.csproj` already exposes internals to `Umbraco.Infrastructure` at line 54.
5. **Constants.Security.SuperUserId = -1**: Defined in `Constants-Security.cs:11`

```
2. **Code Review for Task 17**: Already passed, but was interrupted before marking complete
3. **Update plan document**: Mark remaining tasks as completed once verified
4. **Use finishing-a-development-branch skill**: After Task 18 passes, follow the skill to complete the branch (merge, PR, or cleanup options)
5. **Performance baseline**: After full verification, run the benchmark to establish baseline:
```bash
dotnet run -c Release --project tests/Umbraco.Tests.Benchmarks -- --filter "*PublishingPipeline*"
```
## Other Notes
### Commits Made (most recent first)
- `99b50eaca4` - perf(benchmarks): add publishing pipeline benchmark infrastructure (Task 17)
- `4d898b10d0` - test(integration): add publishing pipeline integration tests (Task 16)
- `a9adbdf3f9` - feat(core): add PerformPublishBranchPipelineAsync method (Task 15)
- `d532c657f9` - chore(di): register publishing pipeline components (Task 14)
- `80b141d2dd` - feat(core): implement PublishingNotifier (Task 13)
- `e7d546f2b6` - feat(core): implement PublishingExecutor with IDocumentRepository (Task 12)
- `85a90b2b93` - feat(core): add IPublishingNotifier interface (Task 9)
- `75bb8ff8f7` - feat(core): add IPublishingExecutor interface (Task 8)
### Performance Gates (from plan)
- Throughput (50+ items): >= 2x improvement over legacy
- Memory allocations: <= legacy
- Correctness: 100% parity with existing tests
### Key Architecture Decisions
- Pipeline components are `internal` (not public API yet)
- Uses `IDocumentRepository` instead of `IContentService` (avoids circular dependencies)
- `PerformPublishBranchPipelineAsync` runs in PARALLEL with legacy path (not replacing it)
- All components registered as **Scoped** services (appropriate for transaction-based operations)

# Handoff: ContentService Performance Review for Refactoring Design
## Task(s)
**Brainstorming session to review the ContentService refactoring design for performance improvements across four areas:**
| Area | Status | Decision |
|------|--------|----------|
| 1. Database Query Efficiency | **Completed** | Batch lookups (4 steps) |
| 2. Memory Allocation Patterns | **Completed** | Aggressive, incremental (7 steps) |
| 3. Concurrency & Locking | **Completed** | Moderate (4 steps) |
| 4. Caching Strategies | **Completed** | Moderate (4 steps) |
Working from the design document at `docs/plans/2025-12-19-contentservice-refactor-design.md`.
## Critical References
1. `docs/plans/2025-12-19-contentservice-refactor-design.md` - The refactoring design being reviewed
2. `src/Umbraco.Core/Services/ContentService.cs` - Current ~3800 line implementation being refactored
3. `src/Umbraco.Core/Services/IContentService.cs` - Interface contract
## Recent changes
No code changes made. This is a design review/brainstorming session.
## Learnings
### Database Query Efficiency Issues Identified
1. **N+1 Query in `GetContentSchedulesByIds`** (ContentService.cs:1025-1049): Loop calling `_idKeyMap.GetIdForKey` for each key individually instead of batch lookup.
2. **Multiple repository calls in `CommitDocumentChangesInternal`** (ContentService.cs:1461+): Separate calls for `GetContentSchedule`, `Save`, and `PersistContentSchedule` within same scope.
3. **Repeated `GetById` calls**: `IsPathPublishable` (line 1070), `GetAncestors` (line 792) make multiple single-item lookups.
**Decision Made**: User approved **Option 1 (Batch lookups)** approach:
- Add batch methods like `GetSchedulesByContentIds(int[] ids)`, `ArePathsPublished(int[] contentIds)`, `GetParents(int[] contentIds)`
- Fix N+1 in key-to-id resolution by adding/using `IIdKeyMap.GetIdsForKeys(Guid[] keys, UmbracoObjectTypes type)`
### Memory Allocation Issues Identified
1. **Excessive ToArray/ToList materializations**: Lines 1170, 814, 2650 - materialize collections just to iterate
2. **String allocations in hot paths**: Lines 1201, 2596-2598 - string concat in loops/move operations
3. **Lambda/closure allocations**: Line 1125-1127 - creates list and closure on every save
4. **Dictionary recreations**: Lines 555-556 - creates dictionary then iterates again
**Pending Decision**: User needs to choose approach:
- **Conservative**: Fix obvious issues (ToArray before iteration, string concat in loops)
- **Moderate**: Add StringBuilder pooling, avoid unnecessary materializations
- **Aggressive**: Full Span/ArrayPool usage, pooled collections
## Artifacts
- `docs/plans/2025-12-19-contentservice-refactor-design.md` - Design document updated to Revision 1.2 with Performance Optimizations section
## Action Items & Next Steps
All performance review tasks completed. Design document updated with:
1. ✅ Database Query Efficiency - 4 batch lookup improvements
2. ✅ Memory Allocation Patterns - 7 incremental optimization steps
3. ✅ Concurrency & Locking - 4 lock optimization steps
4. ✅ Caching Strategies - 4 cache optimization steps
5. ✅ Design document updated at `docs/plans/2025-12-19-contentservice-refactor-design.md` (Revision 1.2)
**Next step**: Proceed to implementation planning with `superpowers:writing-plans`
## Other Notes
### Architecture Context
The refactoring splits ContentService into 5 public services + 2 internal managers:
- `IContentCrudService` (~400 lines) - Create, Get, Save, Delete
- `IContentPublishOperationService` (~1000 lines) - Publish, Unpublish, Scheduling
- `IContentMoveService` (~350 lines) - Move, RecycleBin, Copy, Sort
- `IContentQueryService` (~250 lines) - Count, Paged queries, Hierarchy
- `IContentVersionService` (~200 lines) - Versions, Rollback
- `ContentPermissionManager` (internal) - Permissions
- `ContentBlueprintManager` (internal) - Blueprints
### Key Design Decisions Already Made
1. **Naming**: `IContentPublishOperationService` (not `IContentPublishingService`) to avoid collision with existing API-layer service
2. **Scope Pattern**: Caller-Creates-Scope (Ambient Scope) - nested scopes participate in parent transaction
3. **Lock Coordination**: Acquire locks at highest level that creates scope
4. **Dependency Direction**: Unidirectional - Publish/Move may call CRUD, no reverse dependencies
### Relevant Codebase Locations
- Core interfaces: `src/Umbraco.Core/Services/`
- Repository interfaces: `src/Umbraco.Core/Persistence/Repositories/`
- Scoping: `src/Umbraco.Core/Scoping/`
- ID/Key mapping: `IIdKeyMap` interface for key-to-id resolution

# Handoff: ContentService Test Coverage Analysis for Refactoring
## Task(s)
- **Completed**: Analyzed the ContentService refactoring design document
- **Completed**: Reviewed all existing ContentService test files
- **Completed**: Mapped existing test coverage to proposed service extraction
- **Completed**: Identified test coverage gaps
- **Completed**: Recommended test strategy for the refactoring
- **Planned**: Write specific tests for identified gaps (not started)
## Critical References
1. `docs/plans/2025-12-19-contentservice-refactor-design.md` - The master refactoring design document
2. `tests/Umbraco.Tests.Integration/Umbraco.Core/Services/ContentServiceTests.cs` - Main test file (3707 lines, 91 tests)
## Recent changes
No code changes made - this was a research/analysis session.
## Learnings
### Existing Test Coverage Summary
The ContentService has substantial existing test coverage across 6 test files:
| Test File | Tests | Focus Area |
|-----------|-------|------------|
| `ContentServiceTests.cs` | 91 | Core CRUD, publishing, scheduling, hierarchy |
| `ContentServiceNotificationTests.cs` | 8 | Saving/publishing notification handlers, culture variants |
| `ContentServicePublishBranchTests.cs` | 10 | Branch publishing with various filters, variant/invariant content |
| `ContentServiceVariantTests.cs` | 3 | Culture code casing consistency |
| `ContentServiceTagsTests.cs` | 16 | Tag handling, invariant/variant transitions |
| `ContentServicePerformanceTest.cs` | 8 | Bulk operations, caching performance |
### Proposed Service Extraction (from design doc)
The design splits ContentService into 5 public services + 2 internal managers:
1. `IContentCrudService` - Create, Get, Save, Delete
2. `IContentPublishOperationService` - Publish, Unpublish, Scheduling, Branch
3. `IContentMoveService` - Move, RecycleBin, Copy, Sort
4. `IContentQueryService` - Count, Paged queries, Hierarchy
5. `IContentVersionService` - Versions, Rollback, DeleteVersions
6. `ContentPermissionManager` (internal)
7. `ContentBlueprintManager` (internal)
### Test Strategy Recommendation
**Option A with targeted additions** (recommended approach):
- Keep existing tests as primary safety net (they test via IContentService which becomes the facade)
- Add targeted tests for areas with new risk introduced by the refactoring
### Identified Test Coverage Gaps
| Gap Area | Current State | Why It Matters |
|----------|--------------|----------------|
| **Notification ordering in orchestrated ops** | No explicit test | `MoveToRecycleBin` must unpublish→move in correct sequence |
| **Sort operation** | No test exists | `IContentMoveService.Sort()` has no coverage |
| **DeleteOfType/DeleteOfTypes** | 1 test only | Complex orchestration: moves descendants to bin first |
| **Permission operations** | No tests | `SetPermissions`/`SetPermission` have zero coverage |
| **Transaction boundaries** | Implicit only | When services call each other, ambient scope must work |
| **Lock coordination** | No explicit test | Services acquiring locks within ambient scopes |
| **CommitDocumentChanges internal** | Limited | Culture unpublishing within this method not well tested |
| **Independent service usage** | N/A (new) | Consumers may inject services directly (e.g., `IContentCrudService`) |
### Key Test File Locations
- Integration tests: `tests/Umbraco.Tests.Integration/Umbraco.Core/Services/ContentServiceTests.cs`
- More integration tests: `tests/Umbraco.Tests.Integration/Umbraco.Infrastructure/Services/ContentService*Tests.cs`
- Unit tests referencing ContentService: `tests/Umbraco.Tests.UnitTests/` (13 files, but mostly mock ContentService)
## Artifacts
- `docs/plans/2025-12-19-contentservice-refactor-design.md` - Design document (reviewed)
- This handoff document
## Action Items & Next Steps
1. **Write notification ordering tests** - Verify `MoveToRecycleBin` fires `ContentUnpublishingNotification` before `ContentMovingToRecycleBinNotification`
2. **Add Sort operation tests** - Test `Sort(IEnumerable<IContent>)` and `Sort(IEnumerable<int>)` methods
3. **Expand DeleteOfType tests** - Verify descendant handling and notification ordering
4. **Add permission tests** - Test `SetPermissions` and `SetPermission` methods
5. **Add transaction boundary tests** - Verify ambient scope behavior when services chain calls
6. **Consider independent service tests** - Once services are extracted, add tests that use them directly (not via facade)
7. **Proceed with Phase 1 of refactoring** - Extract `IContentCrudService` first (establishes patterns)
## Other Notes
### Test Infrastructure Observations
- Tests use `UmbracoIntegrationTest` base class with `NewSchemaPerTest` for isolation
- `ContentRepositoryBase.ThrowOnWarning = true` is set in many tests for strict validation
- Custom notification handlers are registered via `CustomTestSetup(IUmbracoBuilder builder)`
- Tests use builder pattern extensively: `ContentTypeBuilder`, `ContentBuilder`, `TemplateBuilder`
### Key Methods That Need Careful Testing During Refactor
Per the design doc's Notification Responsibility Matrix (`docs/plans/2025-12-19-contentservice-refactor-design.md:507-538`):
- `MoveToRecycleBin` - Orchestrated in Facade (unpublish + move)
- `DeleteOfType`/`DeleteOfTypes` - Orchestrated in Facade
- All operations with cancellable notifications need pre/post verification
### Design Doc Key Sections
- Service dependency diagram: lines 39-68
- Method mapping tables: lines 386-496
- Notification responsibility matrix: lines 507-538
- Transaction/scope ownership: lines 105-156

# Handoff: ContentService Phase 0 Implementation Plan Critical Review
## Task(s)
| Task | Status |
|------|--------|
| Critical implementation review of Phase 0 plan | Completed |
| Verify API signatures (Publish, GetContentSchedulesByIds) | Completed |
| Verify DeleteOfType descendant handling behavior | Completed |
| Verify IScopeProvider rollback semantics | Completed |
| Identify duplicate tests in existing test files | Completed |
| Apply fixes 1,2,4,5,6,7,8,9 to the plan | In Progress (interrupted) |
| Answer user question about CI/Phase Gate Enforcement | Completed |
**Working from:** `docs/plans/2025-12-20-contentservice-refactor-phase0-implementation.md`
## Critical References
1. `docs/plans/2025-12-20-contentservice-refactor-phase0-implementation.md` - The Phase 0 implementation plan being reviewed
2. `docs/plans/2025-12-19-contentservice-refactor-design.md` - The parent design document
3. `build/azure-pipelines.yml` - CI pipeline configuration
## Recent changes
No code changes were made - this was a review session preparing to apply fixes.
## Learnings
### API Signatures Verified
- `Publish(IContent content, string[] cultures, int userId)` - Plan uses `new[] { "*" }` correctly
- `GetContentSchedulesByIds(Guid[] keys)` - Plan uses `keys.ToArray()` correctly (Guid[], not int[])
- `EntityPermissionCollection(IEnumerable<EntityPermission> collection)` - Constructor exists as expected
### DeleteOfType Behavior (src/Umbraco.Core/Services/ContentService.cs:3498-3584)
- Queries all content of specified type(s)
- Orders by ParentId descending (deepest first)
- For each item: moves ALL children to recycle bin (regardless of type), then deletes the item
- Test 6 in plan is **correct** - descendants of different types go to bin, same type deleted
### IScopeProvider Rollback Semantics (src/Umbraco.Infrastructure/Scoping/IScopeProvider.cs)
- `CreateScope()` returns `IScope` with `autoComplete = false` by default
- If `scope.Complete()` is NOT called, transaction rolls back on dispose
- Base test class exposes `ScopeProvider` property - no extra using needed for `Umbraco.Cms.Infrastructure.Scoping`
### CI Pipeline Configuration
- **Platform:** Azure Pipelines
- **Test filters for non-release builds:** `--filter TestCategory!=LongRunning&TestCategory!=NonCritical`
- **LongRunning tests (benchmarks) are SKIPPED on normal PRs** - only run on release builds
- Integration tests split into 3 shards by namespace:
- Part 1: `Umbraco.Infrastructure` (excluding Service)
- Part 2: `Umbraco.Infrastructure.Service` (where new tests will live)
- Part 3: Everything else
### Duplicate Test Analysis
No true duplicates found. Existing tests focus on different aspects:
- `ContentEventsTests.cs:802-868` - Sort tests focus on cache refresh events, not notification order
- `ContentServiceTests.cs:1862` - MoveToRecycleBin tests basic functionality, not notification sequence
- `ContentServiceTests.cs:1832` - DeleteOfType exists but doesn't test descendant type handling
## Artifacts
- `docs/plans/2025-12-20-contentservice-refactor-phase0-implementation.md` - Plan to be updated
- `tests/Umbraco.Tests.Integration/Testing/ContentServiceBenchmarkBase.cs` - Already exists (referenced in plan)
## Action Items & Next Steps
### Fixes to Apply to the Plan (User requested 1,2,4,5,6,7,8,9)
1. **[1] API Signatures** - Verified correct, add confirmation note to plan
2. **[2] Remove incorrect using directive** - Task 6 instructs adding `using Umbraco.Cms.Infrastructure.Scoping;` but this is wrong. `ScopeProvider` is already available via base class. Remove this instruction.
3. **[4] Add [NonParallelizable]** - Add `[NonParallelizable]` attribute to `ContentServiceRefactoringTests` class (Task 1 skeleton, line 43-48)
4. **[5] DeleteOfType verified** - Add note confirming behavior is correct
5. **[6] Add benchmark warmup** - Update `MeasureAndRecord` in `ContentServiceBenchmarkBase.cs` to include warmup iteration
6. **[7] Explicit scope creation** - Add note about rollback semantics (verified working as expected)
7. **[8] Add null-checks for template** - Change `FileService.GetTemplate("defaultTemplate")!` to include explicit assertion
8. **[9] Portable JSON extraction** - Replace grep -oP with portable Python script or simpler extraction in Task 10
### Additional Items to Add
- Add note about duplicate test analysis (none found)
- Add note about CI behavior - benchmarks skip on PR builds due to `[LongRunning]` category
- Consider if Phase Gate should run locally before PR or if CI coverage is sufficient
## Other Notes
### Key File Locations
- **ContentService implementation:** `src/Umbraco.Core/Services/ContentService.cs` (~3800 lines)
- **IContentService interface:** `src/Umbraco.Core/Services/IContentService.cs`
- **IScopeProvider:** `src/Umbraco.Infrastructure/Scoping/IScopeProvider.cs`
- **Existing ContentService tests:** `tests/Umbraco.Tests.Integration/Umbraco.Core/Services/ContentServiceTests.cs`
- **ContentEventsTests (sort tests):** `tests/Umbraco.Tests.Integration/Umbraco.Infrastructure/Services/ContentEventsTests.cs`
- **ScopeTests:** `tests/Umbraco.Tests.Integration/Umbraco.Infrastructure/Scoping/ScopeTests.cs`
- **LongRunning attribute:** `tests/Umbraco.Tests.Common/Attributes/LongRunning.cs`
### CI Phase Gate Question (User Asked)
The CI runs ALL integration tests, not just ContentService tests. Tests are split by namespace for parallelization. The new tests will run in "Part 2 of 3" (Umbraco.Infrastructure.Service namespace).
**Important:** Benchmarks marked `[LongRunning]` will be **skipped on PR builds** and only run on release builds. This means:
- The 15 integration tests WILL run on every PR
- The 33 benchmarks will NOT run on PRs (only on releases)
- For local Phase Gate verification, run: `dotnet test --filter "FullyQualifiedName~ContentServiceRefactoring"`

# Handoff: ContentService Refactoring Phase 0 - Test Infrastructure
## Task(s)
Executing Phase 0 of ContentService refactoring using **Subagent-Driven Development** workflow. Phase 0 creates test and benchmark infrastructure to establish baseline metrics before refactoring begins.
**Implementation Plan:** `docs/plans/2025-12-20-contentservice-refactor-phase0-implementation.md`
### Task Status (12 total tasks):
| Task | Description | Status |

## Critical References
1. **Implementation Plan:** `docs/plans/2025-12-20-contentservice-refactor-phase0-implementation.md` - Contains exact test code to add for each task
2. **Subagent-Driven Development Skill:** `~/.claude/plugins/cache/superpowers-marketplace/superpowers/4.0.0/skills/subagent-driven-development/` - Workflow being followed
## Recent changes
- `tests/Umbraco.Tests.Integration/Umbraco.Infrastructure/Services/ContentServiceRefactoringTests.cs` - Added 5 tests (2 notification ordering, 3 sort operation)
- Commits made: `09cc4b022e` (Task 2 initial), amended with fixes, `86b0d3d803` (Task 3)
## Learnings
1. **Subagent-Driven Development Workflow:**
- Dispatch implementer subagent with FULL task text from plan (don't make subagent read files)
- Dispatch spec compliance reviewer to verify implementation matches spec exactly
- If issues found, dispatch fix subagent, then re-review
- Dispatch code quality reviewer only AFTER spec compliance passes
- Mark task complete only when both reviews approve
2. **Test Patterns in Umbraco:**
- Base class `UmbracoIntegrationTestWithContent` provides `Textpage`, `Subpage`, `Subpage2`, `Subpage3`
- `Textpage` is NOT published by default - tests may need to publish parent before creating child content
- Use `ContentBuilder.CreateSimpleContent()` to create fresh test content
- Use `RefactoringTestNotificationHandler.Reset()` before testing notifications
3. **Spec Compliance:**
- First implementation of Task 2 deviated from spec (used fixtures instead of creating content)
- Reviewer caught this and fix was applied successfully
- Lesson: Spec reviewer is critical for catching deviations
## Artifacts
- `tests/Umbraco.Tests.Integration/Testing/ContentServiceBenchmarkBase.cs` - Benchmark base class (committed in Task 0)
- `tests/Umbraco.Tests.Integration/Umbraco.Infrastructure/Services/ContentServiceRefactoringTests.cs` - Integration tests (Tasks 1-3)
- `docs/plans/2025-12-20-contentservice-refactor-phase0-implementation.md` - Full implementation plan with code
## Action Items & Next Steps
Resume using subagent-driven development workflow:
1. **Task 4: Add DeleteOfType tests (Tests 6-8)**
- Dispatch implementer subagent with Task 4 from plan (lines 684-863)
- After implementation, dispatch spec reviewer
- After spec approval, dispatch code quality reviewer
- Mark complete when approved
2. **Task 5: Add permission tests (Tests 9-12)**
- Same workflow as Task 4
- Plan lines 866-1059
3. **Task 6: Add transaction boundary tests (Tests 13-15)**
- Same workflow
- Plan lines 1063-1228
4. **Task 7: Create ContentServiceRefactoringBenchmarks.cs**
- Large file (33 benchmarks) - may take longer
- Plan lines 1231-2386
5. **Task 8: Create ContentServiceBaseTests.cs**
- Unit tests (skeleton with tracking test)
- Plan lines 2389-2657
6. **Tasks 9-11: Verification and baseline capture**
- Run all tests, capture benchmarks, create git tag
## Other Notes
- The implementation plan has gone through 3 critical reviews (v1.1, v1.2, v1.3) - all feedback has been incorporated
- Key revision notes are at the top of the plan document
- Benchmark data sizes are standardized to 10/100/1000 pattern (v1.2)
- Warmup logic was corrected for both destructive and non-destructive benchmarks
- `ContentServiceBase` doesn't exist yet - Task 8 creates tracking test that fails when it's created in Phase 1

- Use `ContentBuilder.CreateSimpleContent()` to create fresh test content
- Use `RefactoringTestNotificationHandler.Reset()` before testing notifications
3. **API Deviations from Plan (discovered in Task 5):**
- `IUserGroupService` is async-only - tests must use `async Task` pattern
- Use `Constants.Security.EditorGroupKey` (Guid) not `EditorGroupAlias`
- `EntityPermission` constructor requires `ISet<string>` (HashSet), not array
4. **Spec Compliance:**
- First implementation of Task 2 deviated from spec (used fixtures instead of creating content)
- Reviewer caught this and fix was applied successfully
- Lesson: Spec reviewer is critical for catching deviations
## Artifacts
- `tests/Umbraco.Tests.Integration/Testing/ContentServiceBenchmarkBase.cs` - Benchmark base class
- `tests/Umbraco.Tests.Integration/Umbraco.Infrastructure/Services/ContentServiceRefactoringTests.cs` - 15 integration tests (Tasks 1-6)
- `docs/plans/2025-12-20-contentservice-refactor-phase0-implementation.md` - Full implementation plan with code
## Action Items & Next Steps
Resume using subagent-driven development workflow starting with **Task 7**:
1. **Task 7: Create ContentServiceRefactoringBenchmarks.cs** (NEXT)
- Large file with 33 benchmarks (~1100 lines)
- Plan lines 1231-2386 contain the full file content
- Dispatch implementer subagent with Task 7 context
- After implementation, dispatch spec reviewer, then code quality reviewer
- This file creates a NEW file, not modifying existing
2. **Task 8: Create ContentServiceBaseTests.cs**
- Unit tests (skeleton with tracking test)
- Plan lines 2389-2657
3. **Tasks 9-11: Verification and baseline capture**
- Run all tests, capture benchmarks, create git tag
## Other Notes
- The implementation plan has gone through 3 critical reviews (v1.1, v1.2, v1.3) - all feedback has been incorporated
- Key revision notes are at the top of the plan document
- Benchmark data sizes are standardized to 10/100/1000 pattern (v1.2)
- Warmup logic was corrected for both destructive and non-destructive benchmarks
- `ContentServiceBase` doesn't exist yet - Task 8 creates tracking test that fails when it's created in Phase 1
- All 15 tests currently in ContentServiceRefactoringTests.cs are passing

# 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:**
```bash
dotnet build tests/Umbraco.Tests.Integration --no-restore -v q
```
3. **Commit the file:**
```bash
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()`

# Handoff: ContentService Refactoring Phase 0 Complete
## Task(s)
**Phase 0 Implementation - COMPLETED**
Executed Tasks 9-11 from the Phase 0 implementation plan (Tasks 0-8 were completed in a prior session):
| Task | Status | Description |
|------|--------|-------------|
| Task 9 | Completed | Run All Tests and Verify - all 15 integration tests pass |
| Task 10 | Completed | Capture Baseline Benchmarks - 32 benchmark entries captured to JSON |
| Task 11 | Completed | Final Verification and Summary - git tag created, all files verified |
Working from plan: `docs/plans/2025-12-20-contentservice-refactor-phase0-implementation.md`
## Critical References
- `docs/plans/2025-12-20-contentservice-refactor-phase0-implementation.md` - The Phase 0 implementation plan (v1.3)
- `src/Umbraco.Core/CLAUDE.md` - Core architecture patterns (notification system, scoping pattern)
- `src/Umbraco.Infrastructure/Services/ContentService.cs` - The service being refactored (target of future phases)
## Recent changes
Made by this session:
- No code changes - Tasks 9-11 were verification and benchmark capture tasks
- Ran benchmarks and captured output to `docs/plans/baseline-phase0.json`
- Created git tag `phase-0-baseline`
- Committed benchmark data: `a079c44afb` "chore: capture Phase 0 baseline benchmarks"
Made in prior session (Tasks 0-8):
- `tests/Umbraco.Tests.Integration/Testing/ContentServiceBenchmarkBase.cs` - Benchmark infrastructure
- `tests/Umbraco.Tests.Integration/Umbraco.Infrastructure/Services/ContentServiceRefactoringTests.cs` - 15 integration tests
- `tests/Umbraco.Tests.Integration/Umbraco.Infrastructure/Services/ContentServiceRefactoringBenchmarks.cs` - 33 benchmarks
- `tests/Umbraco.Tests.UnitTests/Umbraco.Infrastructure/Services/ContentServiceBaseTests.cs` - Tracking test skeleton
## Learnings
1. **Benchmark test failures are test implementation issues, not ContentService bugs:**
- 4 benchmarks fail (GetVersions, GetVersionsSlim, HasChildren, Rollback)
- Root cause: Test assumes `Save()` creates new versions, but it updates existing version
- Root cause: `MeasureAndRecord` warmup causes double-counting in HasChildren test
- These do not block refactoring work
2. **MeasureAndRecord warmup pattern:**
- `ContentServiceBenchmarkBase.cs:63-84` - Action overload with `skipWarmup` parameter
- `ContentServiceBenchmarkBase.cs:93-103` - Func<T> overload always includes warmup
- Use `skipWarmup: true` for destructive operations (Delete, EmptyRecycleBin)
3. **Notification behavior for MoveToRecycleBin:**
- MoveToRecycleBin does NOT fire unpublish notifications - content is "masked" not unpublished
- Tests 1-2 validate this behavior (`ContentServiceRefactoringTests.cs:389-476`)
## Artifacts
**Test Infrastructure:**
- `tests/Umbraco.Tests.Integration/Testing/ContentServiceBenchmarkBase.cs` - Benchmark base class with timing infrastructure
- `tests/Umbraco.Tests.Integration/Umbraco.Infrastructure/Services/ContentServiceRefactoringTests.cs` - 15 integration tests (all pass)
- `tests/Umbraco.Tests.Integration/Umbraco.Infrastructure/Services/ContentServiceRefactoringBenchmarks.cs` - 33 benchmarks (29 pass, 4 fail)
- `tests/Umbraco.Tests.UnitTests/Umbraco.Infrastructure/Services/ContentServiceBaseTests.cs` - Tracking test for Phase 1
**Baseline Data:**
- `docs/plans/baseline-phase0.json` - 32 benchmark timing entries in JSON format
- `benchmark-6db0554b1e.txt` - Raw benchmark output (838 lines)
**Git Tag:**
- `phase-0-baseline` - Marks the commit before baseline data was captured
## Action Items & Next Steps
1. **Phase 0 is complete** - Ready to proceed to Phase 1
2. **Branch decision needed:** User was presented with finishing options:
- Merge back to main locally
- Push and create a Pull Request
- Keep the branch as-is
- Discard this work
3. **Optional: Fix 4 failing benchmark tests** (low priority, does not block refactoring):
- Version creation tests need different approach (publish between saves)
- HasChildren test needs counter reset before measurement

# Handoff: ContentService Phase 1 CRUD Extraction
## Task(s)
**Primary Task**: Execute Phase 1 of ContentService refactoring using subagent-driven development methodology.
**Phase 1 Goal**: Extract CRUD operations (Create, Get, Save, Delete) from the monolithic ContentService (3823 lines) into a dedicated `IContentCrudService` interface and `ContentCrudService` implementation.
### Task Status (8 total):
| # | Task | Status |
|---|------|--------|
| 1 | Create ContentServiceBase Abstract Class | **COMPLETED** |
| 2 | Create IContentCrudService Interface | **COMPLETED** |
| 3 | Create ContentCrudService Implementation | **IN PROGRESS** (not started) |
| 4 | Register ContentCrudService in DI | Pending |
| 5 | Update ContentService to Delegate CRUD Operations | Pending |
| 6 | Add Benchmark Regression Enforcement | Pending |
| 7 | Run Phase 1 Gate Tests | Pending |
| 8 | Update Phase Tracking Documentation | Pending |
## Critical References
1. **Implementation Plan**: `docs/plans/2025-12-20-contentservice-refactor-phase1-implementation.md` - Contains complete task specifications including code to implement
2. **Design Document**: `docs/plans/2025-12-19-contentservice-refactor-design.md` - Overall refactoring architecture
3. **Skill Being Used**: `superpowers:subagent-driven-development` - Dispatch fresh subagent per task with two-stage review
## Recent changes
1. `src/Umbraco.Core/Services/ContentServiceBase.cs` - NEW: Abstract base class with shared infrastructure (DocumentRepository, AuditService, UserIdKeyResolver), Audit/AuditAsync helper methods
2. `src/Umbraco.Core/Services/ContentServiceConstants.cs` - NEW: Static class with `DefaultBatchPageSize = 500`
3. `src/Umbraco.Core/Services/IContentCrudService.cs` - NEW: Interface with 23 methods (Create x6, Read x8, Tree Traversal x5, Save x2, Delete x1)
4. `tests/Umbraco.Tests.UnitTests/Umbraco.Infrastructure/Services/ContentServiceBaseTests.cs:226` - Updated type lookup to `Umbraco.Cms.Core.Services.ContentServiceBase, Umbraco.Core`
## Learnings
1. **Subagent Workflow**: Each task requires three subagents: implementer, spec reviewer, code quality reviewer. Only proceed after both reviews pass.
2. **Test File Discrepancy**: The tracking test in `ContentServiceBaseTests.cs` was written before the final plan. The plan is authoritative - had to update the test to look for the class in `Umbraco.Core` instead of `Umbraco.Infrastructure`.
3. **Implicit Usings**: .NET 10 has `using System;` implicit, so the code quality reviewer's suggestion to add it was not necessary (build succeeded without it).
4. **Spec Accuracy**: The spec's code sample for `ContentServiceBase.cs` was missing `using Umbraco.Cms.Core.Models;` which is required for `UmbracoObjectTypes.Document.GetName()`. Implementation correctly added it.
5. **Commit Hashes**:
- Task 1: `c9ff758aca` - ContentServiceBase + ContentServiceConstants
- Task 2: `b72db59957` - IContentCrudService interface
## Artifacts
- `docs/plans/2025-12-20-contentservice-refactor-phase1-implementation.md` - Complete implementation plan (2396 lines) with all 8 tasks
- `src/Umbraco.Core/Services/ContentServiceBase.cs` - Abstract base class (69 lines)
- `src/Umbraco.Core/Services/ContentServiceConstants.cs` - Constants class (12 lines)
- `src/Umbraco.Core/Services/IContentCrudService.cs` - Interface (251 lines)
## Action Items & Next Steps
1. **Resume Task 3**: Create ContentCrudService Implementation
- Dispatch implementer subagent with Task 3 content from the plan
- This is the largest task (~750 lines of implementation code)
- Includes unit tests in `tests/Umbraco.Tests.UnitTests/Umbraco.Core/Services/ContentCrudServiceTests.cs`
2. **Continue subagent-driven pattern**:
- For each task: dispatch implementer → spec reviewer → code quality reviewer
- Mark task complete only after both reviews pass
- Update TodoWrite after each task completion
3. **Remaining Tasks 4-8**: Follow the plan exactly as specified
4. **Final Steps** (after Task 8):
- Dispatch final code reviewer for entire implementation
- Use `superpowers:finishing-a-development-branch` skill
## Other Notes
- **Methodology**: Using `superpowers:subagent-driven-development` skill - fresh subagent per task with two-stage review (spec compliance, then code quality)
- **Prompt Templates Location**: `/home/yv01p/.claude/plugins/cache/superpowers-marketplace/superpowers/4.0.0/skills/subagent-driven-development/`
- **Build Command**: `dotnet build src/Umbraco.Core/Umbraco.Core.csproj`
- **Test Command Pattern**: `dotnet test tests/Umbraco.Tests.Integration --filter "FullyQualifiedName~ContentService"`
- **The plan has been through 5 critical reviews** - see "Critical Review Changes Applied" sections at bottom of plan document

# Handoff: ContentService Phase 1 CRUD Extraction - Resume at Task 4
## Task(s)
**Primary Task**: Execute Phase 1 of ContentService refactoring using subagent-driven development methodology.
**Phase 1 Goal**: Extract CRUD operations (Create, Get, Save, Delete) from the monolithic ContentService (3823 lines) into a dedicated `IContentCrudService` interface and `ContentCrudService` implementation.
### Task Status (8 total):
| # | Task | Status |
|---|------|--------|
| 1 | Create ContentServiceBase Abstract Class | **COMPLETED** |
| 2 | Create IContentCrudService Interface | **COMPLETED** |
| 3 | Create ContentCrudService Implementation | **COMPLETED** |
| 4 | Register ContentCrudService in DI | **IN PROGRESS** (not started) |
| 5 | Update ContentService to Delegate CRUD Operations | Pending |
| 6 | Add Benchmark Regression Enforcement | Pending |
| 7 | Run Phase 1 Gate Tests | Pending |
| 8 | Update Phase Tracking Documentation | Pending |
## Critical References
1. **Implementation Plan**: `docs/plans/2025-12-20-contentservice-refactor-phase1-implementation.md` - Contains complete task specifications including code to implement
2. **Design Document**: `docs/plans/2025-12-19-contentservice-refactor-design.md` - Overall refactoring architecture
3. **Skill Being Used**: `superpowers:subagent-driven-development` - Dispatch fresh subagent per task with two-stage review
## Recent changes
1. `src/Umbraco.Core/Services/ContentCrudService.cs` - NEW: Full CRUD service implementation (~750 lines)
- 23 public methods (6 Create, 9 Read, 5 Tree Traversal, 2 Save, 1 Delete)
- 7 private helpers (SaveLocked, DeleteLocked, GetContentTypeLocked, etc.)
- Fixed all 5 issues from code quality review (batch audit bug, RecycleBinContent check, null checks, trashed parent validation, notification publishing)
2. `tests/Umbraco.Tests.UnitTests/Umbraco.Core/Services/ContentCrudServiceTests.cs` - NEW: 8 unit tests, all passing
- Fixed mocking issue with ContentCultureInfos (used real instance instead of mock)
## Learnings
1. **Subagent Workflow**: Each task requires three subagents: implementer, spec reviewer, code quality reviewer. Only proceed after both reviews pass.
2. **Test Mocking Limitation**: `ContentCultureInfos.Culture` is a non-virtual property and cannot be mocked. Use real instances: `new ContentCultureInfos("en-US")`.
3. **Lock Ordering**: Always acquire locks in order: ContentTree (write) → ContentTypes (read) → Languages (read). SaveLocked requires both ContentTree and Languages locks.
4. **Validation Placement**: Save validation (PublishedState, name length) MUST be inside SaveLocked, not in public Save method, to prevent race conditions.
5. **GetParent Special Cases**: Must check for both `Constants.System.Root` AND `Constants.System.RecycleBinContent` as parent IDs that should return null.
6. **Commit Hashes**:
- Task 1: `c9ff758aca` - ContentServiceBase + ContentServiceConstants
- Task 2: `b72db59957` - IContentCrudService interface
- Task 3: `0351dc06b4` - ContentCrudService implementation (after all fixes)
## Artifacts
- `docs/plans/2025-12-20-contentservice-refactor-phase1-implementation.md` - Complete implementation plan (2396 lines) with all 8 tasks
- `src/Umbraco.Core/Services/ContentServiceBase.cs` - Abstract base class (69 lines)
- `src/Umbraco.Core/Services/ContentServiceConstants.cs` - Constants class (12 lines)
- `src/Umbraco.Core/Services/IContentCrudService.cs` - Interface (251 lines)
- `src/Umbraco.Core/Services/ContentCrudService.cs` - Implementation (~750 lines)
- `tests/Umbraco.Tests.UnitTests/Umbraco.Core/Services/ContentCrudServiceTests.cs` - Unit tests (8 tests)
## Action Items & Next Steps
1. **Resume Task 4**: Register ContentCrudService in DI
- Dispatch implementer subagent with Task 4 content from the plan
- Add `Services.AddUnique<IContentCrudService, ContentCrudService>();` to `src/Umbraco.Core/DependencyInjection/UmbracoBuilder.cs` around line 300 (before IContentService registration)
- Add integration test to verify DI resolution
- Run: spec reviewer → code quality reviewer → mark complete
2. **Continue with Tasks 5-8**: Follow the plan exactly as specified
- Task 5: Update ContentService to delegate CRUD to ContentCrudService (largest remaining task)
- Task 6: Add benchmark regression enforcement
- Task 7: Run Phase 1 gate tests
- Task 8: Update documentation
3. **Final Steps** (after Task 8):
- Dispatch final code reviewer for entire implementation
- Use `superpowers:finishing-a-development-branch` skill
## Other Notes
- **Methodology**: Using `superpowers:subagent-driven-development` skill - fresh subagent per task with two-stage review (spec compliance, then code quality)
- **Prompt Templates Location**: `/home/yv01p/.claude/plugins/cache/superpowers-marketplace/superpowers/4.0.0/skills/subagent-driven-development/`
- **Build Command**: `dotnet build src/Umbraco.Core/Umbraco.Core.csproj`
- **Test Command**: `dotnet test tests/Umbraco.Tests.UnitTests --filter "FullyQualifiedName~ContentCrudServiceTests"`
- **The plan has been through 5 critical reviews** - see "Critical Review Changes Applied" sections at bottom of plan document
- **Task 4 is small**: Just one line addition to UmbracoBuilder.cs + integration test
