- Refactor migrations and provider to use multiple PostgreSQL schemas, each matching a legacy SQLite database (activitylog, authentication, displaypreferences, library, users). - All tables, foreign keys, and indexes are now schema-qualified; Down migration drops tables by schema. - Provider ensures schemas exist before migrations; entities are mapped to correct schemas in OnModelCreating. - Add support for max-pool-size, min-pool-size, and multiplexing connection options; update logging accordingly. - VACUUM ANALYZE now runs per schema during scheduled optimization. - TruncateAllTablesAsync now truncates tables with schema qualification. - README updated with schema structure, new options, and multiplexing warnings. - CacheDecorator now calls async repository methods using .GetAwaiter().GetResult(), with documentation. - Lays groundwork for full async/await and multiplexing support in the database layer.

|
|
## ⚠️ 4. ChapterRepository - PARTIAL (Repository Layer Only)

|
|
- **Sync Operations**: 6 (3 converted in repository, consumers pending)
|
|

|
|
|
|
### Completed:
|
|
✅ `MediaBrowser.Controller\Persistence\IChapterRepository.cs` - Interface updated

|
✅ `Jellyfin.Server.Implementations\Item\ChapterRepository.cs` - Implementation converted
|
|
|
|
### Pending:
|
|
⏳ `Emby.Server.Implementations\Chapters\ChapterManager.cs` - Service layer wrapper
|
|
⏳ `Emby.Server.Implementations\Dto\DtoService.cs` - Consumer update
|
|
⏳ `Jellyfin.Api\Controllers\ChaptersController.cs` - API endpoint update
|
|
⏳ Other consumers (scheduled tasks, etc.)
|
|
|
|
### Repository Methods Converted:
|
|
1. ✅ `GetChapter()` → `GetChapterAsync()`
|
|
2. ✅ `GetChapters()` → `GetChaptersAsync()`
|
|
3. ✅ `SaveChapters()` → `SaveChaptersAsync()`
|
|
4. ✅ `DeleteChaptersAsync()` - already async

| Repository | Sync Ops | Status | Build | Time |
|
|
|-----------|----------|--------|-------|------|
|
|
| KeyframeRepository | 3 | ✅ DONE | ✅ | ~30min |

|
|
|
|
**Completed**: 3/4 (75%)
|
|
**Remaining**: ChapterRepository consumer updates
|
|

|
|
## 🎯 Next Steps
|
|
|
|
### Option 1: Complete ChapterRepository (Recommended)
|
|
**Estimated Time**: 1-2 hours
|
|
- Update ChapterManager service layer
|
|
- Update API controllers
|
|
- Update all consumers
|
|
- Test and verify build
|
|
|
|
### Option 2: Move to Phase 2
|
|
- Document ChapterRepository as "repository-only async"
|
|
- Begin PeopleRepository conversion
|
|
- Return to finish ChapterRepository later
|
|
|
|
### Option 3: Pause and Present
|
|
- Present Phase 1 results to stakeholders
|
|
- Get approval for continued work
|
|
- Resume with full ChapterRepository conversion
|
|

## 🎓 Lessons Learned
|
|
|
|
### What Worked Well ✅
|
|
1. **Pattern is Proven**: 3 repositories converted successfully
|
|
2. **Backward Compatibility**: Keeping sync methods prevents breaking changes
|
|
3. **Incremental Approach**: Converting one repository at a time is manageable
|
|
4. **Documentation**: Comprehensive docs help track progress
|
|
|
|
### Challenges Encountered ⚠️
|
|
1. **Consumer Identification**: Need to find all usages systematically
|
|
2. **Sync Wrappers**: `.GetAwaiter().GetResult()` needed for sync-by-design methods
|
|
3. **Build Time**: Full rebuilds can be slow
|
|
4. **Token Management**: Large conversions consume significant tokens
|
|
|
|
### Recommendations for Remaining Work 💡
|
|
1. **Use Find Symbol**: Better than text search for finding consumers
|
|
2. **Test Each Layer**: Verify build after each layer (interface → impl → service → API)
|
|
3. **Keep Sync Methods**: Don't remove until all consumers migrated
|
|
4. **Document Wrappers**: Clearly mark where `.GetAwaiter().GetResult()` is used
|
|

## 🎯 Recommendation
|
|
|
|
**Complete ChapterRepository before declaring Phase 1 done.**
|
|
|
|
### Rationale:
|
|
- Only 1-2 hours of work remaining
|
|
- Establishes complete pattern for Phase 2
|
|
- Demonstrates full stack conversion (Repository → Service → API)
|
|
- Better story for stakeholders ("4/4 complete" vs "3/4 complete")
|
|
|
|
### Next Actions:
|
|
1. Update `ChapterManager` service layer (30 min)
|
|
2. Update API controllers (30 min)
|
|
3. Update remaining consumers (30 min)
|
|
4. Test and verify (30 min)
|
|
5. Create completion report (15 min)
|
|
|
|
**Total**: ~2 hours to 100% completion of Phase 1
