Dart:
- notification_service: single _details() builder replaces 13 copies
of the NotificationDetails block
- platform_bridge: _invokeMap() for 34 invoke+decode call sites,
_cachedInvoke() unifies the three TTL/in-flight cache scaffolds
- ffmpeg_service: _promoteTempOutput(), _appendCoverInputArgs(),
single _writeReplayGainTags() and _convertToLossless() for the
ALAC/FLAC twins
- sqlite_helpers.dart: shared openAppDatabase/path-key/migration
helpers for the three database classes
- library_collections: parametrized wishlist/loved/favorite CRUD
- extension_provider: one predicate-based replacedBuiltIn* lookup
Go:
- extension runtime: parseGojaHeaders/coerceGojaBody/doExtensionHTTP
shared by httpGet/httpPost/httpRequest/shortcuts/fetch
- exports_metadata: applyAudioMetadataToResult + successMethodJSON,
APE edit path reuses audioMetadataFromEditFields
- lyrics: lrclibGet() for both LRCLib fetchers
- extension_store: drop hand-rolled strings helpers
marshalJSONString collapses 62 identical marshal-and-return blocks in the
gomobile exports; jsError/jsSuccess collapse 135 goja extension-response
maps; the two MusicBrainz fetchers share one request+retry helper; the
extension-HTTP default User-Agent block and fileExists get single homes.
No exported signature changes.
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.
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
gofmt -r rewrite of all 506 interface{} occurrences to the any alias
(identical semantics), drop unused spec constants into comments, rename
unused parameters to _, convert three if-else chains to tagged
switches, and use slices.ContainsFunc for the private-IP check. No
behavior change; the whole package is now gofmt-clean.
Pure mechanical move within package gobackend — no signature or behavior
change, so the gomobile binding surface is identical. exports.go (4,141
lines) now holds only availability/dir/duplicate/filename exports; the
rest moved to exports_{musicbrainz,download,reenrich,metadata,lyrics,
deezer,extensions,store,library}.go along existing responsibility
boundaries.
