- Add context cancellation check between pagination pages in GetArtistReleaseGroups
for responsive graceful shutdown during large discography fetches.
- Eliminate double DB query on cache hit by having GetCachedReleases return
[]ExternalRelease directly instead of just a count, avoiding a redundant
second query in SyncArtistDiscography.
- Update cache_test.go to match new GetCachedReleases return type.
- Format main.go (pre-existing whitespace issue).
- Add CacheTTL default (24h) in config applyDefaults — without this,
omitting cache_ttl from config silently defeats the entire caching
mechanism (TTL=0 means cached data is never served)
- Fix pagination to use total Count instead of checking if last page
was short — avoids wasting a rate-limit token when total count is
an exact multiple of 100
- Preserve user-set IsIgnored flags across re-syncs — previously,
DELETE+INSERT in the sync transaction reset all ignore flags to
false, losing user preferences on every cache-expiry re-sync
- Check context cancellation on cache-hit code path — previously,
ctx.Err() was not checked between cache check and returning cached
data, violating the cancellation contract
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.
