From 5ca432744579588e6bf443073fdfa15c9596225b Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Jorge=20Ch=C3=A1vez=20Bornios?= Date: Mon, 3 Aug 2026 01:26:52 -0700 Subject: [PATCH 01/14] feat: v1.0.0.1 - InstantSearch, GIN indexes, PG->SQLite export, optimization UI - InstantSearchService: sub-15ms search via pg_trgm GIN indexes, ILIKE fallback - ExportToSqliteService: export PG data directly to .db binary (no external tools) Auto-detects native jellyfin.db path; creates tables from PG schema if absent; DELETE+INSERT in 10k-row WAL transactions if .db already exists - OptimizeIndexesTask: weekly scheduled task; inject ILogger via constructor - PostgresDatabaseProvider: extract RunOptimizationsAsync as static method Fixes 503 on ApplyOptimizations - no longer requires provider instance (Current) - PostgresController: ApplyOptimizations uses RunOptimizationsAsync static; new endpoints: ExportToSqliteDefaultPath, ExportToSqliteProgress, StartExportToSqlite, InstantSearch, OptimizationStatus, ApplyOptimizations - PostgresServiceRegistrator: registers ExportToSqliteService + InstantSearchService - configurationPage.html: 3 tabs; Migration tab adds PG->SQLite export card; Maintenance tab adds Optimization card with Apply button + GIN index status list; fix JS: check both camelCase/PascalCase for trgmAvailable and isValid; poll status every 5s (12 attempts) after applying optimizations - PluginConfiguration: MinPoolSize, MaxAutoPrepare fields - build.yaml + csproj: version 1.0.0.1 - README.md + README.en.md: accurate docs for all new features --- .../Api/PostgresController.cs | 188 +++++++- .../Class1.cs | 228 +++++++++- ...ellyfin.Database.Providers.Postgres.csproj | 2 +- .../PluginConfiguration.cs | 34 ++ .../PostgresServiceRegistrator.cs | 3 + .../Services/ExportToSqliteService.cs | 413 ++++++++++++++++++ .../Services/InstantSearchService.cs | 256 +++++++++++ .../Services/MaintenanceService.cs | 49 +++ .../Tasks/OptimizeIndexesTask.cs | 76 ++++ .../Web/configurationPage.html | 281 +++++++++++- README.en.md | 106 ++++- README.md | 61 ++- build.yaml | 2 +- 13 files changed, 1672 insertions(+), 27 deletions(-) create mode 100644 Jellyfin.Database.Providers.Postgres/Services/ExportToSqliteService.cs create mode 100644 Jellyfin.Database.Providers.Postgres/Services/InstantSearchService.cs create mode 100644 Jellyfin.Database.Providers.Postgres/Tasks/OptimizeIndexesTask.cs diff --git a/Jellyfin.Database.Providers.Postgres/Api/PostgresController.cs b/Jellyfin.Database.Providers.Postgres/Api/PostgresController.cs index b91ebb4..51da28d 100644 --- a/Jellyfin.Database.Providers.Postgres/Api/PostgresController.cs +++ b/Jellyfin.Database.Providers.Postgres/Api/PostgresController.cs @@ -83,6 +83,16 @@ public sealed class BackupRequest public string?
