Use shared coordinators for queueing FLAC replacements and batch metadata enrichment from album and queue screens. Keep selection lifecycle handling in each screen and synchronize a settings snapshot once per phase.
Cover cancellation, partial failure, screen disposal, and settings changes between preview and apply.
Apply resolved metadata with copyWith and retain the existing field precedence. Keep UPC, preview URLs, and source-only fields when enrichment updates other tags.
Extract the pure merge helpers and add regression tests for field preservation.
Reuse the conversion output lifecycle for M4A conversion and native FLAC suffix correction. Reserve destination names atomically, reject empty output, and clean partial files while preserving the input on failure.
Add regressions for existing outputs, concurrent conversions, staging, and cleanup.
Fixes#368.
Reopening a Spotify playlist from "recent access" showed no tracks,
while the first view (right after pasting the URL) worked fine.
Root cause traced across two layers:
1. Go: ExtURLHandleResult (the parsed shape of an extension's handleUrl()
return value) never captured a top-level `id` for the handled
resource. Track/album/artist results carry their own id inside their
nested metadata, but a plain playlist result has no such object, so
its id was silently dropped everywhere from the goja parser through
to the JSON the Dart side receives.
2. Dart: TrackState had nowhere to put that id even if it existed
(only playlistName), so recording a "recent" playlist access stored
the playlist's *name* as if it were its id. Reopening it later fed
that name into PlaylistScreen's provider-guessing logic
(legacyProviderIdFromResourceId, which only recognizes legacy
"provider:id" prefixes), which naturally failed and fell through to
a hardcoded Deezer metadata fetch using a Spotify playlist's name as
the resource id - guaranteed to return nothing.
Fix, matching the "generic API, not per-provider checks" architecture
in CONTRIBUTING.md:
- go_backend/extension_provider_wrapper.go: add ExtURLHandleResult.ID.
- go_backend/extension_goja_convert.go: parse it from the handler's
return value.
- go_backend/exports_extensions.go: surface it in the JSON response.
- lib/providers/track_provider.dart: add TrackState.playlistId,
populated from the response's `id` field for playlist results.
- lib/screens/home_tab.dart: record the real playlist id (falling back
to the name only if a provider never supplies one) and pass both the
id and the already-known provider id forward to PlaylistScreen.
- lib/screens/playlist_screen.dart: PlaylistScreen gains a
metadataProviderId param that takes priority over guessing from the
id's shape.
- lib/screens/home_tab_recent.dart: pass the recent-access entry's
stored providerId through when reopening a playlist.
- lib/utils/provider_resource_ids.dart: extract the
known-id-vs-guessed-id preference into a small, directly testable
resolvePreferredMetadataProviderId helper.
Note: this fixes the common case (an extension already reported its
own id as the source provider for the URL it handled). If a provider
never supplies an id for its handleUrl() playlist result, playlistId
stays null and behavior is unchanged from before this fix - no
regression, just not a complete fix for that narrower case, since
that would require changes in extension-side JS code outside this
repo.
Tests:
- go_backend/extension_goja_convert_url_handle_test.go: the new ID
field round-trips from a handler's return value, and stays empty
when the handler doesn't supply one.
- test/provider_resource_ids_test.dart: resolvePreferredMetadataProviderId
prefers a known provider id, falls back to the legacy-prefix guess,
treats a blank known id as unknown, and returns null for the
unprefixed-id-with-no-known-provider case from #368 itself.
Verification: go build/vet/test and flutter analyze/test all green.
Fixes#439, likely also #302.
Reported: on iOS, the download folder silently reverts to the default
SpotiFLAC folder after starting a download (and stays reverted after
closing and reopening the app).
_processQueue ran an iCloud/writable-path shape check against the
persisted downloadDirectory string and, if it looked like iCloud Drive
or failed the structural writable-path check, called
setDownloadDirectory() to reset it to the default folder. That call
passes no iosBookmark argument, so it also wipes the user's
security-scoped bookmark in the persisted settings - permanently, not
just for the current run.
This check ran unconditionally, even when a bookmark was already
present for that folder. A folder picked from Files can legitimately
have a persisted path that looks like iCloud Drive, or that fails this
generic structural check, while the bookmark itself still grants real
write access - the bookmark is the actual source of truth, and the
queue already has a separate, correct bookmark-resolution step right
after this one (StartAccessingIosBookmark, with its own proper
failure handling that fails the queued items with a clear message
instead of destroying the setting). The earlier path-shape check just
never deferred to it.
lib/utils/file_access.dart: extract the run/skip decision into
shouldValidateIosOutputDir(isIOS, isSafMode, outputDir,
downloadDirectoryBookmark) - skips whenever a bookmark is present -
and use it in download_queue_provider.dart in place of the inline
condition. Kept as a plain function taking isIOS as a parameter since
Platform.isIOS itself can't be exercised from a host test run.
test/file_access_ios_test.dart covers: runs for a plain app-folder
path, skips when a bookmark is present (the exact #439 case), skips
off iOS, skips in SAF mode, and skips when there's no output dir yet.
Verification: flutter analyze and flutter test (224 tests, all green,
including the 5 new ones) both clean.
