- 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.
Previously, the migration system would attempt to back up the legacy SQLite library.db file even when running with non-SQLite providers (e.g., PostgreSQL), causing startup errors. This was due to SQLite-specific migrations not being filtered out during backup requirement aggregation. This commit adds filtering to exclude migrations marked as RequiresSqlite from backup processing unless the provider is actually SQLite (currently unsupported). This prevents erroneous backup attempts and ensures only relevant migrations and backups are processed. Documentation has been updated to explain the issue and solution.
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.

- Added db-quick.ps1 for interactive diagnostics and index management
- Updated Add-All-Indexes.bat to use db-config.ps1
- Added Fix-ItemValues-Performance.ps1 to create 3 critical indexes on ItemValues, addressing 1.3B row seq scan issue
- Updated performance_indexes.sql with new ItemValues indexes and ANALYZE
- Updated diagnostics.sql and database_report.txt for improved output and clarity
- All scripts and docs now reference the new config and index optimization workflow
- Update version to 11.0.0-PostgreSQL-PREVIEW in assemblies, installer, and build scripts
- Default web directory is now "wwwroot" across all platforms
- Configuration manager now creates .example files if missing
- Set PostgreSQL as default database with sensible options
- Postgres provider ensures database exists before table checks
- Add docs for marker conflict fixes and startup.json path issues
- Version string in logs/UI uses informational version
- Installer output filename and wizard show PREVIEW suffix
- Documentation summarizes version bump and verification steps
Configured QuerySplittingBehavior.SplitQuery in PostgresDatabaseProvider to optimize performance for queries with multiple Include() statements. This prevents cartesian explosion, eliminates EF Core warnings, and aligns with best practices for handling related collections in PostgreSQL.
SQLite provider removed from service collection and runtime database options. Microsoft.Data.Sqlite package added to Jellyfin.Server for migration routines (SQLite → PostgreSQL). Migration service updated to always use PostgreSQL. SqliteExtensions restored for migration helpers. SQLite migration test deleted. Documentation added to explain migration-only support and deployment impact. No breaking changes for users migrating from SQLite; deployment size increases (~68 MB) for cross-platform SQLite DLLs.
- Rewrote README.md to highlight PostgreSQL features, installer, and migration, with quick start and full docs index
- Moved all markdown documentation files to docs/ for better organization; updated links accordingly
- Added .gitignore rules to exclude all PublishProfiles folders; removed tracked publish profile XMLs
- Preserved original README as README.original.md; added README_GENERATION.md and DOCUMENTATION_ORGANIZATION.md
- Cleaned root directory, improved navigation, and clarified platform-specific instructions
- All DLLs now output to lib\[Configuration]\[TargetFramework]\ at repo root (see Directory.Build.props)
- .gitignore updated to exclude /lib/
- On first run, startup.json is auto-generated with OS-appropriate default paths (Windows, Linux, macOS, or portable)
- Removes null/example config; generated config is immediately usable and clearly documented
- Extensive new documentation: build output, startup.json logic, visual guides, and code proofs
- Publish profile now deletes existing files for clean deploys
- No breaking changes: existing startup.json files are preserved
- Improves first-run UX, deployment, and cross-platform consistency
Add logic to initialize at least one user if the startup wizard is not completed, both during application startup and in the startup user API. After user creation, reload the user entity with all related navigation properties to ensure the in-memory user object is fully populated. Also update build and publish metadata files.
Integrated Jellyfin.CodeAnalysis as a project reference across core and test projects. Added centrally managed code analysis and style enforcement packages (IDisposableAnalyzers, Microsoft.CodeAnalysis.BannedApiAnalyzers, SerilogAnalyzer, SmartAnalyzers.MultithreadingAnalyzer, StyleCop.Analyzers) to all affected projects. Updated dependency graphs, asset files, and build scripts to ensure analyzers run during builds, enforcing consistent code quality and style rules throughout the codebase. Removed custom warning properties to rely on analyzer enforcement.
- Added Jellyfin.Database.Providers.Postgres project with full EF Core migration support for PostgreSQL.
- Implemented automatic database creation and privilege assignment on startup.
- Generated initial migration and model snapshot for PostgreSQL schema.
- Updated build, test, and dependency files to include PostgreSQL provider and Npgsql packages.
- Added PowerShell script for generating and testing PostgreSQL migrations.
- No changes to application logic outside database provider/migration infrastructure.
