Vladimir Zagainov Date: Tue, 26 May 2026 12:15:28 +0300 Subject: [PATCH 03/72] feat: implement rate limiting and caching layer for MusicBrainz provider - Add golang.org/x/time/rate dependency for token-bucket rate limiting - Replace custom channel-based rate limiter with rate.NewLimiter(1, 1) - Add context.Context support to doGet for cancellation - Add cached_at column to external_releases via migration 005 - Implement cache hit/miss queries with TTL-based filtering - Add CacheStats type for tracking cached RGIDs - Update ExternalRelease struct with CachedAt field - Add rate limiting tests (1 req/sec enforcement, burst behavior) - Add cache tests (hit, miss, expired, mixed, empty artist) - Update migration count test for new migration ---

feat: implement MusicBrainz sync orchestration with caching and upsert Creates internal/musicbrainz/sync.go with SyncArtistDiscography function that orchestrates the full flow: cache check via GetCachedReleases, fetch from MusicBrainz API on cache miss, filter via FilterReleaseGroups, and upsert into external_releases via database.SaveExternalRelease. Includes SyncArtistDiscographyWithFilter variant for per-artist type filtering. All functions support context cancellation. 14 new tests cover cache hit/miss, status/type filtering, context cancellation, idempotency, API errors, and full XML pipeline integration. --- docs/plans/2026-05-21-musicbrainz-provider.md | 14 +- internal/musicbrainz/sync.go | 130 +++ internal/musicbrainz/sync_test.go | 798 ++++++++++++++++++ 3 files changed, 935 insertions(+), 7 deletions(-) create mode 100644 internal/musicbrainz/sync.go create mode 100644 internal/musicbrainz/sync_test.go diff --git a/docs/plans/2026-05-21-musicbrainz-provider.md b/docs/plans/2026-05-21-musicbrainz-provider.md index 04775aa..29bbce0 100644 --- a/docs/plans/2026-05-21-musicbrainz-provider.md +++ b/docs/plans/2026-05-21-musicbrainz-provider.md @@ -75,13 +75,13 @@ Implement a MusicBrainz API provider with strict 1 request/second rate limiting, - [x] run tests - must pass before next task ### Task 4: Implement database integration and sync orchestration -- [ ] create `internal/musicbrainz/sync.go` with SyncArtistDiscography function -- [ ] implement upsert logic: INSERT OR REPLACE into external_releases table -- [ ] add cached_at column to external_releases table via migration -- [ ] implement context.Context support for cancellation -- [ ] write tests for database upsert operations -- [ ] write integration tests with in-memory SQLite -- [ ] run tests - must pass before next task +- [x] create `internal/musicbrainz/sync.go` with SyncArtistDiscography function +- [x] implement upsert logic: INSERT OR REPLACE into external_releases table +- [x] add cached_at column to external_releases table via migration (done in Task 3 as migration 005) +- [x] implement context.Context support for cancellation +- [x] write tests for database upsert operations +- [x] write integration tests with in-memory SQLite +- [x] run tests - must pass before next task ### Task 5: Wire up provider in application entry point - [ ] update `cmd/naviwatcher/main.go` to initialize MusicBrainz client diff --git a/internal/musicbrainz/sync.go b/internal/musicbrainz/sync.go new file mode 100644 index 0000000..c0700c7 --- /dev/null +++ b/internal/musicbrainz/sync.go @@ -0,0 +1,130 @@ +package musicbrainz + +import ( + "context" + "fmt" + "time" + + "naviwatcher/internal/database" +) + +// SyncArtistDiscography synchronizes an artist's discography from MusicBrainz +// into the local external_releases table.

Zagainov Date: Tue, 26 May 2026 14:10:22 +0300 Subject: [PATCH 08/72] fix: address code review findings Remove dead code: duplicate ExternalRelease/Artist/ParsedArtist structs in model.go, ParseArtist/mbArtist/mbArtistData in client.go, ArtistTypeFilter and related filtering functions in api.go, SyncArtistDiscographyWithFilter in sync.go, and CacheStats/IsArtistCacheValid in cache.go. Fix bugs: SaveExternalRelease now stores NULL instead of empty string for zero CachedAt; sync upserts are now transactional with stale release cleanup; getCachedReleases returns int instead of *CacheStats; doGet uses url.Values for proper query encoding of MBID. Fix tests: removed duplicate TestRun_GracefulShutdown, removed dead code (_ = dbPath) from TestNewApp, fixed assertions in httptest handler goroutine to avoid data race, increased rate limiter timing tolerance, removed Client.Close() calls (no-op removed), fixed sync test cache expiry to use UPDATE instead of 0 TTL races. Fix formatting: cancel()}() formatting in main.go, error format string in sync.go. --- cmd/naviwatcher/main.go | 6 +- cmd/naviwatcher/main_test.go | 34 --- internal/database/external_releases.go | 8 +- internal/musicbrainz/api.go | 97 ++------- internal/musicbrainz/api_test.go | 274 +------------------------ internal/musicbrainz/cache.go | 42 +--- internal/musicbrainz/cache_test.go | 104 ++-------- internal/musicbrainz/client.go | 43 +--- internal/musicbrainz/client_test.go | 50 ++--- internal/musicbrainz/model.go | 25 --- internal/musicbrainz/model_test.go | 31 --- internal/musicbrainz/sync.go | 85 +++----- internal/musicbrainz/sync_test.go | 264 ++++++++++-------------- 13 files changed, 199 insertions(+), 864 deletions(-) diff --git a/cmd/naviwatcher/main.go b/cmd/naviwatcher/main.go index 0ac59b2..d153b34 100644 --- a/cmd/naviwatcher/main.go +++ b/cmd/naviwatcher/main.go @@ -45,7 +45,8 @@ func main() { go func() { sig := <-sigCh log.Printf("Received signal %v, shutting down...", sig) -

Adds ErrArtistNotFound sentinel so callers can distinguish missing artists, and wires routes via the enhanced ServeMux path wildcard. --- docs/plans/2026-07-19-notifier-webui-sync.md | 10 +- internal/database/artist_settings.go | 4 + internal/database/artist_settings_test.go | 6 +- internal/database/database.go | 6 + internal/navidrome/sync.go | 3 +- internal/web/handlers.go | 246 +++++++++++++++- internal/web/server.go | 5 + internal/web/server_test.go | 285 +++++++++++++++++++ internal/web/templates/archive.html | 48 ++++ internal/web/templates/artist.html | 80 ++++++ internal/web/templates/dashboard.html | 2 +- 11 files changed, 682 insertions(+), 13 deletions(-) create mode 100644 internal/web/templates/archive.html create mode 100644 internal/web/templates/artist.html diff --git a/docs/plans/2026-07-19-notifier-webui-sync.md b/docs/plans/2026-07-19-notifier-webui-sync.md index c4217b0..c71bf42 100644 --- a/docs/plans/2026-07-19-notifier-webui-sync.md +++ b/docs/plans/2026-07-19-notifier-webui-sync.md @@ -125,11 +125,11 @@ name collisions.) - [x] run tests - must pass before task 8 ### Task 8: Web UI — artist detail + archive + ignore actions -- [ ] artist page: local albums (Subsonic) + found missing (MB cache) + ignore buttons -- [ ] archive page: `GetIgnoredReleases` with restore action -- [ ] POST handlers: `SetReleaseIgnored(rgid, true/false)`; "ignore all singles of artist" toggles `artist_settings.ignore_singles` -- [ ] write tests: ignore sets flag + removes from dashboard missing; restore clears flag; auth enforced on POST -- [ ] run tests - must pass before task 9 +- [x] artist page: local albums (Subsonic) + found missing (MB cache) + ignore buttons +- [x] archive page: `GetIgnoredReleases` with restore action +- [x] POST handlers: `SetReleaseIgnored(rgid, true/false)`; "ignore all singles of artist" toggles `artist_settings.ignore_singles` +- [x] write tests: ignore sets flag + removes from dashboard missing; restore clears flag; auth enforced on POST +- [x] run tests - must pass before task 9 ### Task 9: Verify acceptance criteria - [ ] run full suite `go test ./...` — all pass diff --git a/internal/database/artist_settings.go b/internal/database/artist_settings.go index 1b3fc8b..96665e5 100644 --- a/internal/database/artist_settings.go +++ b/internal/database/artist_settings.go @@ -2,6 +2,7 @@ package database import ( "database/sql" + "errors" "fmt" ) @@ -17,6 +18,9 @@ func GetArtistSettings(db *DB, id string) (*ArtistSettings, error) { id, ).Scan(&s.ID, &s.Name, &mbid, &s.IgnoreSingles, &s.IgnoreCompilations, &s.Monitored) if err != nil { + if errors.Is(err, sql.ErrNoRows) { + return nil, ErrArtistNotFound + } return nil, err } s.MBID = mbid.String diff --git a/internal/database/artist_settings_test.go b/internal/database/artist_settings_test.go index 7b50977..7a83758 100644 --- a/internal/database/artist_settings_test.go +++ b/internal/database/artist_settings_test.go @@ -44,7 +44,7 @@ func TestGetArtistSettings_Found(t *testing.T) { } } -// TestGetArtistSettings_NotFound verifies that a missing artist returns sql.ErrNoRows. +// TestGetArtistSettings_NotFound verifies that a missing artist returns ErrArtistNotFound. func TestGetArtistSettings_NotFound(t *testing.T) { db, err := New(":memory:") if err != nil { @@ -53,8 +53,8 @@ func TestGetArtistSettings_NotFound(t *testing.T) { defer db.Close() _, err = GetArtistSettings(db, "nonexistent") - if err != sql.ErrNoRows { - t.Errorf("expected sql.ErrNoRows, got %v", err) + if err != ErrArtistNotFound { + t.Errorf("expected ErrArtistNotFound, got %v", err) } } diff --git a/internal/database/database.go b/internal/database/database.go index ae84623..8af7f8e 100644 --- a/internal/database/database.go +++ b/internal/database/database.go @@ -2,6 +2,7 @@ package database import ( "database/sql" + "errors" "fmt" "time" @@ -13,6 +14,11 @@ type DB struct { conn *sql.DB } +// ErrArtistNotFound is returned by artist lookups when no row matches the given +// ID.
