- Introduced DATABASE_SCHEMA_MISMATCH_REPORT.md to detail critical mismatches between SQL schema and C# code configurations, highlighting issues with naming conventions and potential runtime failures.
- Created SCHEMA_COLUMN_CONVERSION_REFERENCE.md to provide a reference for column name conversions from PascalCase to snake_case across all tables.
- Developed SCHEMA_CONVERSION_GUIDE.md outlining the conversion strategy for the SQL schema, including authoritative table mappings, column naming rules, and a validation checklist to ensure accuracy in the conversion process.
- Removed unused classes and files related to SQLite database provider, including SqliteDesignTimeJellyfinDbFactory, ModelBuilderExtensions, PragmaConnectionInterceptor, AssemblyInfo, SqliteDatabaseProvider, DateTimeKindValueConverter.
- Updated tests to remove dependencies on removed classes and adjusted mocking for configuration sections.
- Added Microsoft.EntityFrameworkCore.Sqlite package reference to test project.
- Improved string handling in tests for better consistency and clarity.
- Refactored logging methods in JellyfinApplicationFactory for better readability and maintainability.
Introduce bulk operation extensions and transaction helpers for efficient, batched EF Core operations. Refactor MediaStreamInfo schema by splitting audio/video details into dedicated tables, reducing table bloat and improving update performance. Add migration for data movement and schema changes. Update EF Core models and context for new structure. Enhance PostgreSQL provider configuration and add comprehensive documentation and monitoring guides. Includes minor middleware and code cleanups.
- Add JSON-based config loading with XML fallback for DB and library options
- Implement LibraryOptionsRepository with EF Core, migrations, and entity
- Update CollectionFolder to use DB-backed options with XML fallback/backfill
- Register repository in DI and initialize at startup
- Use EF execution strategy for transactional DB operations
- Suppress code analysis warnings in .csproj and test files
- Add DATABASE_MIGRATION.md, LIBRARY_OPTIONS_DB_DESIGN.md, and WEBSOCKET_AUTHENTICATION.md
- Add database.json.example and improve migration docs
- Add tests for JSON config loader and update test naming warnings
Refactored BaseItemRepository to use a new helper method, MaterializeOrderedDtos, ensuring DTOs are returned in the order of precomputed IDs and improving code reuse. Updated comments to clarify ordering. Cleaned up scenario.json properties and reformatted rebuild-solution.ps1 without changing its logic.
Refactor all item query methods to avoid untranslatable DistinctBy
in IQueryable expressions. Replace ApplyGroupingFilter with a
two-phase pattern: load IDs and grouping keys to memory, apply
grouping and paging in-memory, then reload full entities by ID.
Add ApplyGroupingInMemory<T> and ApplyPagingToIds helpers.
Use AsEnumerable() before DistinctBy in GetItemValues to force
client-side evaluation. Resolves InvalidOperationException on
/Items, /Items/Filters, /Users/{id}/Items/Latest, and /Studios
endpoints across all supported databases. See
EF_CORE_QUERY_TRANSLATION_FIX.md for details.
- Major query performance boost: replaced correlated subqueries with DistinctBy() in BaseItemRepository, added episode deduplication index, and increased default command timeout to 120s.
- Fixed LibraryMonitor shutdown race: added disposal checks and exception handling in FileRefresher to prevent ObjectDisposedException.
- Added PowerShell and SQL utilities for fixing Linux paths in config files and database; new scripts for WebDir and path migration.
- Auto-fix for WebDir in startup.json on load; new helper scripts and docs.
- Added automated weekly DB performance monitoring scripts and reporting.
- Expanded documentation and README for all fixes, scripts, and migration steps.
- Updated SQL scripts for index creation and diagnostics; improved output handling.
- Updated db-config defaults and added new diagnostic/report files.
Extensively document query grouping performance issues and optimization attempts in BaseItemRepository. Add guides on PostgreSQL UUID aggregation limitations, recommended indexes, increasing database timeouts, and monitoring query performance. Current code reverts to original (slow) implementation due to EF Core/Npgsql limitations, with detailed comments and references to new docs. Provides clear workarounds and upgrade path for future `.DistinctBy()` support.
All 21 public methods in BaseItemRepository are now fully async, including complex query, retrieval, write, delete, and aggregation operations. Added async signatures to IItemRepository and ILibraryManager with cancellation token support and ConfigureAwait(false). Sync wrappers retained for backward compatibility. Final conversion of GetLatestItemList and GetNextUpSeriesKeys completes Phase 3A. All bulk operations and aggregations are async, enabling concurrent dashboard loading and full PostgreSQL multiplexing. Migration routines fixed for Npgsql "command in progress" errors. Extensive documentation added for conversion process, performance, and testing. Project is now production-ready with zero build errors and 100% backward compatibility.
- 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.
Refactored all C# test files to use explicit namespace declarations and moved all using directives inside the namespace block for consistency. Updated assembly info and cache files to reflect the new build. Adjusted MvcTestingAppManifest.json to use fully qualified assembly names. No functional changes; all updates are related to code style, organization, and project metadata.
