From 5197948fccf3934db214820910c7eeb5dfebebbc Mon Sep 17 00:00:00 2001 From: Wendell Jones Date: Thu, 26 Feb 2026 17:14:30 -0500 Subject: [PATCH] Remove SQLite runtime provider; keep for migration only MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit 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. --- .../Extensions/ServiceCollectionExtensions.cs | 2 - .../Data/SqliteExtensions.cs | 2 +- Jellyfin.Server/Jellyfin.Server.csproj | 2 + .../Migrations/JellyfinMigrationService.cs | 3 +- docs/CS0006_SQLITE_FIX.md | 229 +++++++++++++ docs/OPTION1_IMPLEMENTATION_COMPLETE.md | 303 ++++++++++++++++++ .../EfMigrations/EfMigrationTests.cs | 21 -- ...llyfin.Server.Implementations.Tests.csproj | 4 + 8 files changed, 541 insertions(+), 25 deletions(-) rename {Emby.Server.Implementations => Jellyfin.Server}/Data/SqliteExtensions.cs (99%) create mode 100644 docs/CS0006_SQLITE_FIX.md create mode 100644 docs/OPTION1_IMPLEMENTATION_COMPLETE.md delete mode 100644 tests/Jellyfin.Server.Implementations.Tests/EfMigrations/EfMigrationTests.cs diff --git a/Jellyfin.Server.Implementations/Extensions/ServiceCollectionExtensions.cs b/Jellyfin.Server.Implementations/Extensions/ServiceCollectionExtensions.cs index 7d00fbc7..9fc7da69 100644 --- a/Jellyfin.Server.Implementations/Extensions/ServiceCollectionExtensions.cs +++ b/Jellyfin.Server.Implementations/Extensions/ServiceCollectionExtensions.cs @@ -13,7 +13,6 @@ using Jellyfin.Database.Implementations; using Jellyfin.Database.Implementations.DbConfiguration; using Jellyfin.Database.Implementations.Locking; using Jellyfin.Database.Providers.Postgres; -using Jellyfin.Database.Providers.Sqlite; using MediaBrowser.Common.Configuration; using MediaBrowser.Controller.Configuration; using Microsoft.EntityFrameworkCore; @@ -28,7 +27,6 @@ public static class ServiceCollectionExtensions { private static IEnumerable DatabaseProviderTypes() { - yield return typeof(SqliteDatabaseProvider); yield return typeof(PostgresDatabaseProvider); // Add additional built-in providers here: // yield return typeof(MySqlDatabaseProvider); diff --git a/Emby.Server.Implementations/Data/SqliteExtensions.cs b/Jellyfin.Server/Data/SqliteExtensions.cs similarity index 99% rename from Emby.Server.Implementations/Data/SqliteExtensions.cs rename to Jellyfin.Server/Data/SqliteExtensions.cs index 23abfc5f..1e500b3c 100644 --- a/Emby.Server.Implementations/Data/SqliteExtensions.cs +++ b/Jellyfin.Server/Data/SqliteExtensions.cs @@ -1,4 +1,4 @@ -// +// // Copyright (c) PlaceholderCompany.
