Drops the YouTube-backed second catalog source entirely: the
Local/External split on Track/Album collapses into single concrete
entities, Artist/TrackArtist/ExternalTrack/ExternalAlbum and the
YouTube service/download pipeline (yt-dlp, MassTransit consumer,
routing slip) are deleted, and mixes now source discovery only from
local listening history. Includes the RemoveYouTubeIntegration EF
Core migration and matching Worker/deploy/compose cleanup (no more
yt-dlp/python/deno in the Worker image, no thumbnail-cache/YtDlp
config sections).
New Playback:AllowAnonymousListening / Playback:AnonymousFragmentSeconds
settings control whether a request without a session can stream at all,
and if so, whether it's limited to a fragment instead of the full track:
- GET /tracks/{id}/stream and GET /youtube/tracks/{videoId}/stream no
longer require authorization outright; the handlers gate on the config
instead, so both keep working exactly as before when it's off (the
default).
- The fragment cap is enforced by the Streaming Gateway, not the client:
the stream ticket now carries an optional maxBytes claim (computed from
AnonymousFragmentSeconds and the transcoder's known bitrate), and
TicketValidationMiddleware clamps the Range it forwards to SeaweedFS to
stay under it — synthesizing one if the request didn't send one, and
answering 416 outright if the requested range starts past the cap.
- A YouTube track that hasn't been provisioned server-side yet streams
straight from YouTube's CDN, bypassing the Gateway entirely — there's no
way to cap that, so an anonymous request for one is refused (409) instead
of silently handing out an uncapped stream.
- ListeningHistory has a non-nullable UserId, so anonymous plays simply
don't get recorded rather than trying to force a row through the FK.
Also fixes a real, pre-existing bug this surfaced: the AppSettings.Development.json
of the Api, Worker, and StreamingGateway all pointed StreamTicket/Workers
paths at "../../deploy/..." — one directory short of deploy/'s actual
location at the repo root relative to each project's own folder. Docker
never hit this (it mounts an absolute /keys path), so it had apparently
never been exercised via `dotnet run` before.
Converts all 73 test source files from file-scoped (namespace X;) to
block-scoped (namespace X { ... }) declarations, re-indenting their
contents accordingly. Matches the existing convention already used in
several production files (e.g. Musify.Infrastructure.Configuration,
Musify.Application.Contracts).
Mechanical change only, done with a script, verified with a full
rebuild (0 warnings, 0 errors) and test run (257/257 passing).
- Directory.Packages.props: xunit 2.9.3 -> xunit.v3 4.0.0, bump
xunit.runner.visualstudio to the matching 4.0.0
- All 5 test csproj: xunit -> xunit.v3 package reference, add
<OutputType>Exe</OutputType> (v3 test projects are standalone
executables)
- backend/global.json: opt dotnet test into the new MTP-native mode
(.NET 10 SDK removed the old VSTest bridge for MTP-based test
projects like xunit v3)
- IAsyncLifetime implementations (HandlerTestBase, ApiTestFixture,
InfrastructureTestFixture, StorageServiceTests): v3's IAsyncLifetime
now IS IAsyncDisposable, so InitializeAsync/DisposeAsync return
ValueTask instead of Task. ApiTestFixture specifically now overrides
WebApplicationFactory.DisposeAsync instead of implementing
IAsyncLifetime.DisposeAsync explicitly, since v3 collapses both to
the same single DisposeAsync slot
- Replaced CancellationToken.None with TestContext.Current.CancellationToken
across the suite (a v3-only API) and added it to every call that
was silently omitting a CancellationToken argument, per the new
xUnit1051 analyzer warnings that came with the v3 package
Verified: dotnet build (0 warnings, 0 errors) and dotnet test, 250/250
passing under the new MTP runner.
Two xUnit projects, wired into Musify.slnx under a /Tests/ folder that
mirrors Core/ and Hosts/:
Musify.Domain.Tests Value-object logic (TrackAudio/TrackPictures'
IsProcessed/IsFailed/IsInProgress). Entities are
otherwise anemic EF models with no behavior to
test.
Musify.Application.Tests All ~45 Application handlers and services
(Albums, Tracks, PlayLists, Users, Mixes,
YouTube, plus TrackStreamIssuer,
UploadIntentValidator, YouTubeTrackProvisioner).
IDatabase exposes DbSet<T> directly, so handlers compose real LINQ queries
against it — that can't be expressed with a mock (no IQueryable provider
behind one). TestSupport/TestDatabase.cs is instead a real DbContext on a
private SQLite in-memory connection per test (fresh per test since xUnit
instantiates the test class per test method): fast, no external dependency,
and — unlike EF Core's InMemory provider — SQLite enforces real foreign keys
and supports transactions, which two handlers need. External dependencies
(IStorageService, IEventBus, IYouTubeMusicService, ...) are substituted with
NSubstitute.
TestSupport/TestEntities.cs and TestConfigurations.cs build fully-populated
domain entities and configuration POCOs with sensible defaults for every
required member, so no test method needs to fill in properties it doesn't
care about, and no builder ever hands back null.
Also, needed to make the Application layer itself testable without a real
Postgres or user-secrets:
- DatabaseDesignTimeFactory now falls back to the Database__ConnectionString
env var, and DesignSettings.json is optional — unblocks the `migrate`
one-shot container from deploy/compose.yml, which hit the same gap.
- Directory.Packages.props: xunit, xunit.runner.visualstudio, NSubstitute,
Microsoft.EntityFrameworkCore.Sqlite (pinned to the same 10.0.8 as the rest
of EF Core), Microsoft.NET.Test.Sdk, coverlet.collector. Also pins
SQLitePCLRaw.bundle_e_sqlite3 to 2.1.13 — EFCore.Sqlite 10.0.8 pulls 2.1.11
transitively, which has a known high-severity advisory (GHSA-2m69-gcr7-jv3q).
- backend/.dockerignore excludes Tests/: no application Dockerfile needs it
in its build context.
162 tests, all green: `dotnet test backend/Musify.slnx`.
