Nine golangci-lint failures accumulated across M7 #352, #372, and
6d1709c that were never surfaced because test-go never ran green long
enough to reach the lint step. The first push to land cleanly through
vet (the M7 #363 slice) ran lint and exposed them.
- errcheck: discard the error on defer Close() in collage.go,
collage_test.go, and server_test.go.
- gofmt -s: re-run on config.go and playlists_test.go.
- goimports: move the stray "time" import from the local-module group
to stdlib in server_test.go.
- revive unused-parameter: rename ctx to _ on stubScanner.Scan and
fakeLidarrUnmonitorer.UnmonitorTrack (test stubs); on
tracks.Service's adminID, add //nolint:revive directive rather than
renaming because the HTTP handler passes admin.ID (a real authed-user
UUID) and the existing comment already flags it as reserved for the
audit-log follow-up.
AppendTracks / RemoveTrack / Reorder run in single transactions and
update the denormalized rollups (track_count, duration_sec). Reorder
uses a +10000 offset to bump every row out of the position range
before writing the new positions, sidestepping PK conflicts during
rewrite.
GenerateCollage composes a 600x600 JPEG from the first 4 album
covers, with a slate-tinted fallback for missing cells. Synchronous,
called inline after every mutating operation. SVG-rasterized fallback
is a follow-up — slice 1 ships with a solid placeholder.
Create / Get / List / Update / Delete with the visibility model from
the spec: private by default, owner-only mutations, public read for
non-owners. Update uses sqlc's CASE-WHEN-flag pattern for PATCH-style
partial updates without writing N variants.
Delete cleans up the cached cover file from disk best-effort. Track
operations (Append/Remove/Reorder) and the collage generator land
in subsequent tasks.
Also adds playlists + playlist_tracks to dbtest.ResetDB's truncate
list so integration tests in this package start from a clean state.
