radoslav-orlov: "create lossy copies of lossless tracks" only recognized FLAC, even though ALAC/
WAV/AIFF/DSD are now quality-profile formats. the FLAC knowledge was hardcoded in 3 separate
places (the import path, the Lossy Converter scan, and the fix executor) — exactly how a format
gets added in one spot but not another.
kettui-style fix — one canonical seam both sites route through, instead of 3 more string edits:
- new core/quality/lossless.py: is_lossless_format / is_lossless_audio_path (pure; injects a
codec probe for the ambiguous .m4a/.mp4 — ALAC vs AAC — so the decision stays testable with no
I/O), LOSSLESS_FORMATS (single source of truth, derived-consistent with model.tier_score), and
the lossy_output_would_overwrite_source safety invariant.
- create_lossy_copy + the Lossy Converter scan + repair_worker._fix_missing_lossy_copy all route
through it. SQL pre-filters by candidate extensions, then each file is confirmed (probing .m4a).
- SAFETY: a lossy copy must never be written over its own source — an .m4a ALAC source + AAC
target lands on the same .m4a path, and ffmpeg runs with -y. all three sites now bail on the
overwrite case BEFORE ffmpeg (the existing delete-original guard was too late — the source was
already clobbered). dropped a vestigial mutagen FLAC import; updated FLAC-only UI strings.
19 tests: full seam coverage (formats, the .m4a ALAC/AAC probe branch, candidate extensions, the
overwrite guard), a tier-model consistency test that fails if the lossless set drifts, and import-
site wiring tests — WAV now converts (was rejected), and the .m4a-ALAC+AAC overwrite case proves
ffmpeg NEVER runs. 286 quality/import/repair tests green, ruff clean.
`_create_finding` silently dedup-skipped re-discovered issues but
the caller incremented `findings_created` regardless. So a re-scan
that found the same issues as a prior scan reported 364 findings
in the badge while 0 NEW pending rows hit the db, leaving the
findings tab empty.
`_create_finding` now returns bool (True on insert, False on
dedup-skip / db error). All 16 repair jobs updated to only
increment `findings_created` on True. Added `findings_skipped_dedup`
counter surfaced in scan log: "Done: X scanned, 0 fixed, 0
findings (363 already existed), 0 errors".
Also fixed a missing `job_id` kwarg in album_tag_consistency that
was silently breaking finding creation for that scan.
GitHub issue #476 (gabistek, Docker on Arch host): "Auto-Fill" / "Fix
Selected" on the Album Completeness findings page returned
"Could not determine album folder from existing tracks" for every album.
Reproduces on any setup where the media-server library lives outside the
SoulSync transfer/download folders — Docker is the headline case but
native installs that point Plex at a NAS via SMB hit it too.
Root cause: `core/repair_worker.py:_resolve_file_path` only probed the
transfer + download folders. Docker users have their Plex/Jellyfin
library bind-mounted at /music (or similar) — neither configured in
SoulSync. Every existing track got silently treated as missing, so
`album_folder` stayed None and the fix workflow bailed.
The same incomplete logic was duplicated four more times in the
repair_jobs/ modules, all with the same bug. Album Completeness was
just the most user-visible — the same setups were also producing false
"missing file" findings from Dead File Cleaner, silent skips in
MBID Mismatch Detector, etc.
The web server already had the correct logic at
`web_server.py:_resolve_library_file_path` (probes transfer + download
+ Plex-reported library locations + user-configured library.music_paths).
The repair workers had never been updated to match.
Fix:
- New `core/library/path_resolver.py` extracts the union logic into a
single shared function `resolve_library_file_path()`. Probes (in
order, deduped): explicit transfer/download kwargs, config-derived
soulseek.transfer_path/download_path, Plex-reported library
locations (when a plex_client is passed), user-configured
library.music_paths. Each defensive: malformed config or a flaky
Plex client degrades to the dirs that did succeed.
- `core/repair_worker.py:_resolve_file_path` becomes a delegating
wrapper preserving the legacy signature, with a new `config_manager`
kwarg. All 15 in-tree call sites updated to thread
`self._config_manager` through.
- `core/repair_jobs/dead_file_cleaner.py`,
`mbid_mismatch_detector.py`, and `lossy_converter.py` get the same
treatment: duplicate function replaced with a thin wrapper, call
sites pass `context.config_manager`.
- `core/repair_jobs/acoustid_scanner.py` and
`unknown_artist_fixer.py` (which used to import from repair_worker)
now call the shared resolver directly with `context.config_manager`.
Side benefit: every other repair job (Dead File Cleaner, MBID
Mismatch Detector, Lossy Converter, AcoustID Scanner, Unknown Artist
Fixer) also stops missing files in the media-server library mount.
Single fix unblocks five user-visible features.
Tests: `tests/library/test_path_resolver.py` — 20 cases covering all
four base-dir sources, suffix-walk algorithm, dedup, defensive paths
(None plex client, malformed config entries, raising config_manager.get,
broken plex attribute access), Docker path translation. Full suite
1677 passed locally.
WHATS_NEW entry under '2.4.2' dev cycle.
The lossy converter fix handler now reads delete_original from its
own job settings (repair.jobs.lossy_converter.settings.delete_original)
instead of the global lossy_copy.delete_original. Defaults to false.
Separate from the per-download Blasphemy Mode toggle in Settings.
New library maintenance job that scans for FLAC files missing a lossy
copy (MP3/Opus/AAC) and creates findings. Fix action converts via
ffmpeg using the configured codec/bitrate from Settings. Supports
Blasphemy Mode (delete original + update DB path). Finding details
store codec/bitrate from scan time for consistency. Disabled by
default, manual-run only, no auto-schedule.
