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.
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.
- Add GetArtistReleaseGroups method with pagination support
- Implement status filtering (exclude Bootleg/Promotion/Pseudo-Release)
- Implement type filtering (include Album/Single/EP/Compilation)
- Add per-artist type filtering hooks (ArtistTypeFilter) for Web UI
- Add NormalizeString and NormalizeArtistName for fuzzy matching prep
- Add ReleaseGroup.ToExternalRelease conversion method
- Write comprehensive table-driven tests for filtering logic
- Write tests for normalization functions (18 cases)
