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.
Stale snapshot (queue wedged forever): the service is START_NOT_STICKY,
so a process kill or reboot mid-batch froze the state file at
is_running:true with nothing ever rewriting it. Adoption then set
isProcessing and polled that flag indefinitely; restored items sat at
downloading/queued until the user intervened. Adoption and the
reconcile poll now check DownloadService.isServiceRunning() (three
consecutive dead polls in the loop), reconcile whatever the worker
finished, requeue in-flight items, clear the run id, and hand the batch
back to the Dart queue.
Adoption gate race (duplicate executors): adoption was gated on
_canUseAndroidNativeWorker, which reads extension state that loads
asynchronously after startup and settings toggles the user may have
flipped mid-run. A background batch surviving task removal was then
orphaned while the Dart queue re-downloaded the same items. Adoption
now only requires Android; request contexts that cannot be built yet
(extensions still loading) are retried on each reconcile poll.
Queue replacement race (superseded worker kept running): startNativeWorker
only cancelled the coroutine, which cannot interrupt the blocking
gomobile call, and it reset the shared cancel flag the old loop checks -
so a replaced worker kept downloading its old batch, and its finally
block wrote is_running:false over the new run's snapshot and stopSelf'd
the service underneath it. Replacement now cancels the old run's Go
downloads and FFmpeg work first, and workers carry a generation token:
a superseded generation exits at the next checkpoint and skips the
final snapshot write and service teardown. An invalid replacement
payload no longer stops the service while a run is active.
The finalizer's catch-all cleanup deleted the finished output for any
exception, including ones thrown after the file was already published
to SAF. A failed history insert (SQLITE_BUSY against the concurrently
open Flutter connection, disk full, or a schema-version mismatch that
would throw on every download), an external .lrc write error, or a
quality-metadata refresh failure destroyed a complete, valid track and
forced a full re-download.
- Track outputPublished and skip cleanupFailedFinalizationOutput once
the file reached its final destination
- Make the history insert, external LRC write, and quality metadata
refresh non-fatal (log + history_written:false instead of failing
the item)
A persisted SAF tree grant can die silently (folder deleted or renamed,
SD card removed, app data reset, system revocation). Downloads then fail
with no recovery path beyond digging through Settings.
- Add isSafTreeAccessible bridge method: the grant must still be in the
system's persisted permission list and the tree writable
- Show a warning banner in Files & Folders when the saved SAF folder is
no longer accessible, with an inline re-select action
- In the download error dialog, replace Retry with a Re-select folder
action when the failure is a lost folder grant (Android SAF or iOS
bookmark); a successful re-pick retries the item automatically
- Share the folder-access error messages as constants so the UI can
match on them reliably
Add a platform bridge to finish session grants on Android and iOS with
JSON success validation, let users paste callback URLs from the
clipboard, and auto-dismiss the verification help dialog after grant.
Raise sourceCompatibility/targetCompatibility to Java 25 and Kotlin jvmTarget to JVM_25 across app and subprojects, and CI java-version to 25 (Kotlin 2.3.21 supports JVM_25). Bump targetSdk to 37 to match compileSdk. Building locally requires Flutter to use JDK 25 (flutter config --jdk-dir).
Pin file_picker to exact 12.0.0-beta.5 since beta.7's published artifact fails to compile on Android. Set compileSdk = 37 so receive_sharing_intent 1.9.0 (compiles against SDK 37) builds against a stable platform.
Add a setting that relaxes the SSRF guard so extensions and built-in network code can reach private/local/loopback targets, for users routing traffic through a local proxy or custom DNS. Disabled by default. Wired end-to-end: Go backend (SetAllowPrivateNetwork toggles isPrivateIP guard), Android/iOS platform bridge, Dart settings model/provider, and a toggle in Download settings.
Classify verification-required and rate-limit errors from extensions, propagate Retry-After seconds through the download fallback, report session-grant success/failure, and add a completeGrant action fallback in the runtime.
Decrypt AC-4 via the FFmpeg mov muxer with a -f mov fallback, then repair the output to a standards-compliant ISO MP4: inject the dac4 config box from the encrypted source, normalize the QuickTime container/sample entry, and write iTunes metadata (incl. cover and lyrics) natively. Codec-keyed and generic, so it applies to any extension that returns AC-4 streams. Wired through PlatformBridge/MainActivity for both SAF and local decrypt paths.
The GL renderer string is empty when Flutter shell args are built (no GL context yet), so the GPU-pattern check never matched Sony Walkman devices and Impeller crashed in the Vivante driver's glLinkProgram. Match MANUFACTURER 'SonyAudio' (distinct from Xperia 'Sony') and add Vivante GC GPU patterns.
FFmpeg's MP4 muxer drops ISRC and label, so write them as iTunes freeform atoms natively after every M4A embed pass. The metadata screen now reads all edited fields from the file on load (file is the source of truth), fixing edited values reverting to stale cached values after reopening.
- app: clear displayFeatures so bottom sheets/dialogs center on large/foldable screens
- edit metadata sheet: card sections, modern label-above inputs, elegant collapsible headers, removed title icon
- convert + batch convert: modern card-based sheets; shared BatchConvertSheet widget
- queue: keep selection toolbar hidden until modal close animation finishes
- 24-bit and In Library badges now use primary dynamic color
- artist skeleton: remove duplicate name/listeners lines, keep cover placeholder
- files settings: own filename-format controller in a StatefulWidget to fix use-after-dispose crash
WAV/AIFF: library scan, quality probe, native tag read/write via embedded ID3 chunk (RIFF id3 / AIFF ID3), cover art, ReadFileMetadata, ExtractLyrics, and FLAC<->WAV/AIFF conversion (PCM, bit-depth preserved via ffprobe). Treat WAV/AIFF as lossless across all convert sheets (no bitrate picker, Lossless labels) via isLosslessConversionTarget. Native MIME maps for SAF. Redesign the track metadata three-dot menu to a settings-style grouped card with a single divider above Share.
- Re-enrich: reject candidates that don't match title/artist/album unless exact ISRC match
- Respect settings.embedLyrics instead of hardcoding true in re-enrich flows
- Skip lyrics resolution in NativeDownloadFinalizer when not needed
- Apple Music lyrics: use direct catalog API with token scraping instead of Paxsenix search
- Support ELRC/ELRCMultiPerson/Plain formats in Apple Music lyrics response
- Add confidence check in metadata auto-fill to prevent applying wrong metadata
- Add tests for stricter re-enrich matching logic
The HIGH-quality lossy format picker can now produce an AAC/M4A 320 kbps output alongside MP3 and Opus. FFmpegService.convertM4aToLossy/convertAudioFormat, the Dart queue pipeline, the Kotlin finalizer, and the library database format helper all route .m4a through a unified aac codec path and tag the resulting file with the M4A metadata writer. The Lossy Format setting gains a new option, and the track metadata convert dialog lists AAC next to the other targets.
Apple Music lyrics gain a 'eLRC word sync' switch (default off). When disabled the pax-to-LRC formatter strips inline word timestamps, producing line-synced LRC that is safer for players that choke on eLRC; enabling it restores the previous word-by-word behaviour. The change propagates through SetLyricsFetchOptions and invalidates the global lyrics cache on toggle.
Broad l10n migration: roughly 400 previously hardcoded English strings across queue, settings, track metadata, repo, audio analysis, setup and extension screens now live in the ARB catalog, with matching plural/placeholder forms. No behaviour change beyond localisation. Existing and new unit tests (lyrics eLRC toggle and Dart settings round-trip) pass.
The SAF and local post-download branches used to rush an ffmpeg 'M4A to FLAC' remux whenever the output extension was .flac, which silently upscaled AAC or EAC3 streams into a lossless container. Each branch now mirrors the native worker by probing the primary audio codec before converting: lossless sources (and true FLAC-in-MP4 files) stay in their native container with the right extension, while genuine ALAC/WAV payloads still get remuxed.
Add an outputExt field to DownloadRequestPayload so the Go backend always knows the user-requested container, and use it together with _shouldRequestContainerConversion to pick the right behaviour for shouldPreserveNativeM4a and the Kotlin finalizer. Decryption descriptors no longer force M4A preservation on their own; the codec probe already makes that call correctly.
