A RemoteViews widget (no new dependencies) shows the active track,
artist, queue count, and a coarse progress bar, with tap-to-open.
DownloadService pushes updates only on discrete events — track or
status changes and 25% progress steps, never per byte — matching the
battery discipline; the last state persists so launcher refreshes
render after process death. Colors use Material You system tokens on
API 31+ with static light/dark fallbacks below.
The Go MusicBrainz genre and album-artist ISRC lookups only ran
automatically at download time. The tag editor's auto-fill section
gains a Fetch from MusicBrainz button that bridges both exports in one
channel call (sparing the 1 req/s budget) and fills the fields as
editable suggestions; nothing is written until Save.
Remove the never-called checkAvailability chain end to end (Dart bridge +
provider, Android/iOS MethodChannel handlers, Go exports) and stop restoring
its persistent lookup cache on every cold start; the legacy prefs key is
cleared on next cache reset.
Delete dead Go: romaji.go (test-only), the no-op pre-warm chain
(PreWarmTrackCache/PreWarmCache/…), retired Download stubs, and a batch of
exports with no Dart/Kotlin/Swift/Go caller. Kept GetTrackCacheSize/
ClearTrackIDCache (Settings cache screen), SetAllowedDownloadDirs and
Clear/GetItemProgress (live test seams).
Dedup: single updateFlacVorbis + replaceFlacPictures helper behind the six
FLAC tag writers; merge byte-identical extractCommentFrame/extractLyricsFrame
into extractLangTextFrame.
go build/vet + 237 go tests, flutter analyze + tests green.
Deezer localizes artist and genre names by IP geolocation when no language
is given, so users behind e.g. Arabic-region IPs got Arabic metadata on an
English device (VPN 'fixed' it). The app's display language is now pushed
to the backend and sent as Accept-Language, with an en-US default.
Fixes#480
Decrypt can emit a raw FLAC stream; the AC-4 repair step fed it to the
MP4 box parser, which failed with a garbage atom type whose control
bytes then broke the unescaped Kotlin error JSON (FormatException in
Dart). Guard the repair call by extension, sniff the box type in Go as
a second layer, and build platform error JSON with JSONObject.quote.
Coordinated rename of the nine store-named bridge surfaces: Go
exports (InitExtensionStoreJSON -> InitExtensionRepoJSON etc.),
method-channel strings, the Kotlin and Swift handlers, and the Dart
PlatformBridge methods. Channel strings verified 1:1 across
Dart/Kotlin/Swift; gomobile bindings match the new export names.
Android MediaStore APIs untouched. store_registry_url pref key kept
for existing users. Local Android/iOS builds need the gobackend
AAR/xcframework rebuilt; CI does this in the release workflow.
MainActivity duplicated the whole SAF helper cluster (sanitizeFilename,
truncation, ensureDocumentDir, createOrReuseDocumentFile, ...) and both
classes synchronized on separate locks, so a foreground SAF write racing
a service-worker write into the same tree was never serialized and could
produce duplicate documents. One shared home, one lock. normalizeExt
adopts the trim-first variant; mimeTypeForExt is the union of all three
copies (adds wav/aiff/ogg coverage everywhere).
EditFileMetadata now answers native_mp3/native_ogg/native_m4a and only
falls back to method=ffmpeg when a native editor rejects the file, so
every editor UI switches off the remux path without Dart changes. The
download embed path does the same for flac/mp3/opus/m4a. Side effect:
ReplayGain for MP3/Opus was silently never written (the old dispatch
answered ffmpeg and the caller ignored it) - it is now written natively.
Covers all three editors with synthetic-file tests, including foreign-tag
preservation and stco offset tracking.
Decrypt, HIGH conversion, and container conversion wrote ffmpeg output
directly under a real audio name in the final directory, so a process kill
mid-conversion left a partial file that library scans listed as a corrupt
track. Outputs now stream into a '.partial<ext>' sibling (invisible to
scans, real trailing extension so ffmpeg still infers the muxer) and are
fsynced and renamed into place only on success.
Also fixes the delete-then-rename in the ffmpeg tag embed (a kill between
the two lost the file entirely - now renames over the original) and
flushes+fsyncs SAF output streams before staged documents are published.
The 1s snapshot poll re-read and re-parsed the whole worker state file
— which retains every completed item's result (history row, possibly
full synced lyrics; 1.5-5 KB each) for the entire run — then
re-serialized it across the channel and re-iterated it on the Dart UI
isolate. Late in a 1000-track batch that is megabytes parsed several
times per second, on the Android main thread.
Pollers now echo back the state_serial of the last snapshot they fully
processed; when the state has not advanced, the native side serves a
cached compact header (no items, no results, no settings) merged with
the small progress delta — steady-state polls are O(1) regardless of
batch size, and the full payload is delivered exactly once per state
transition. The channel handler also reads and parses off the main
thread now, matching its neighbours.
When a provider delivers a lossy/unknown stream, the native finalizer
preserved the container but kept the requested .flac name, so every
metadata/ReplayGain write treated the file as FLAC and failed with
"failed to write FLAC metadata: failed to parse FLAC file: fLaC head
incorrect" — on the first download, on every retry (the file is never
deleted from public storage), on every manual edit attempt, and the
history backfill re-probed the same file on every app launch forever.
- Finalizer now renames a preserved lossy/unknown container away from
its .flac name to match the real content (aac/MP4 -> .m4a, mp3, opus),
mirroring the Dart pipeline, so the correct tag writer is picked
- EditFileMetadata sniffs MP4 content before taking the .flac branch
and reports what is actually wrong (rename to .m4a) instead of the
cryptic parse error
- The history audio-metadata backfill remembers paths whose probe
failed permanently (unparseable content) and stops reselecting them
on every launch; transient failures (missing file, unmounted volume)
still retry
MainActivity only overrode provideFlutterEngine, so the activity's
fragment delegate treated the plugin-cached engine as its own
(createFlutterFragment forwards shouldDestroyEngineWithHost, default
true) and destroyed it when the activity finished, while the engine
stayed registered in AudioServicePlugin's FlutterEngineCache. When
AudioService stopped afterwards, disposeFlutterEngine() called
destroy() on the already destroyed engine and crashed the app with
"Cannot execute operation because FlutterJNI is not attached to
native".
Mirror audio_service's own AudioServiceFragmentActivity: expose the
plugin engine as a cached engine (getCachedEngineId), never destroy it
with the host (shouldDestroyEngineWithHost = false), and pre-create it
in onCreate. The plugin remains the engine's sole owner and disposes
it only once, when the service stops with no activity attached.
- Verification challenge no longer abandons the batch: batch mates the
worker cancel would mark skipped are requeued and fenced from later
snapshot applications, and the adoption loop restarts the queue for
requeued items when the run ends
- Pause vs cancel race: a cancelled result with no pause flag set waits
up to 1.5s for the pause intent to land on the main looper before
being classified as a permanent skip
- Stale Go cancel flag: new ResetDownloadCancel export (wired through
Android and iOS bridges) drops a pre-registered cancel with no active
download; retryItem/retryAllFailed call it so the first retry of a
cancelled-before-start item no longer aborts instantly
- Reconcile-loop errors now cancel the native worker and clear the run
id before marking items failed, instead of leaving the service
downloading a batch the UI already wrote off
- All SAF downloads now write under a staged .partial name; the handler
itself promotes to the final name for legacy callers (the foreground
Dart queue), so a killed process can never leave a half-written file
that the exists check then accepts as complete forever. Stale partials
are removed before reuse since fd truncation is best-effort on some
providers.
- The exists-check/create/write/publish sequence is serialized per
target file (tree URI + dir + name); two concurrent downloads that
sanitize to the same display name can no longer interleave writes
into one document — the second waits and dedupes via already_exists.
- Replacing an existing final file now renames it aside and deletes it
only after the staged copy holds the final name; a failed rename
restores it instead of losing both copies.
- The FFmpeg command pump always delivers a result for every claimed
command id, including on exception or cancellation; previously a
cancel mid-command stranded the Go post-processing call forever with
the finalizer thread blocked inside it.
