Changed the last used publish profile in Jellyfin.Server.csproj.user from Windows x64 to Linux x64. Also updated the lastUpdateTime in scenario.json to reflect recent activity.
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.
All 41 projects now target .NET 11.0 (PREVIEW). Updated tasks.md to reflect 100% completion of upgrade and validation, including build, test, manual smoke tests, performance checks, and deployment verification. Updated execution-log.md and scenario.json with final validation results and timestamps. Changed Jellyfin.Server.csproj.user to use SelfContained-Win-x64 publish profile. No code changes required for this tier; all tests pass except integration tests pending PostgreSQL infrastructure.
Added a detailed .NET 11.0 (PREVIEW) upgrade plan (plan.md) outlining a bottom-up migration strategy, dependency analysis, risk management, testing, and success criteria for the Jellyfin solution. Introduced assessment.md, assessment.json, and assessment.csv with comprehensive compatibility analysis for all 41 projects, confirming no blocking issues. Added Risk Management Strategies.md detailing mitigation and rollback procedures. Also included scenario.json describing the upgrade scenario and selected strategy. No existing files were changed.
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.
