Sixth cluster: the bulk-hydration get_<source>_playlist_states endpoints for
the five sources that build the identical per-entry dict + {"states": [...]}
shape (Tidal, Deezer, Qobuz, Spotify-Public, iTunes-Link) ->
core.discovery.endpoints.get_playlist_states(states, *, error_label,
info_log_label=None), wired via _get_source_playlist_states.
iTunes-Link is the only one of the five without the "Returning N stored ..."
info log, so info_log_label is optional (iTunes passes None to suppress it).
NOT folded in: the YouTube/ListenBrainz get_all_*_playlists endpoints. They
return {"playlists": [...]} (different key) with a different field set
(url / created_at / playlist, no discovery_results) and filter out
mirrored_/profile-scoped entries — genuinely divergent, kept as-is.
Tests: +4 (list build + last_accessed bump + exact shape, empty, optional ids
default None, missing-required-field -> 500). Full discovery suite: 183 passed.
web_server.py: -116 lines.
Fifth cluster: reset_<source>_playlist for the four sources with byte-
identical bodies (Tidal, Deezer, Qobuz, Spotify-Public) ->
core.discovery.endpoints.reset_playlist(states, key, *, label,
not_found_message), wired via _reset_source_playlist. Resets phase/status to
'fresh', clears discovery/sync fields, cancels any discovery_future, and
preserves the original playlist payload.
Left with their own bodies (genuinely divergent):
- YouTube: status -> 'parsed' (not 'fresh'), no download_process_id, logs the
playlist name, "reset to fresh state".
- ListenBrainz: status -> 'cached', logs playlist title, returns
{"success": True, "phase": "fresh"} (different payload), _lb_state_key.
- iTunes-Link: state.update(...), no info log, "iTunes Link reset to fresh
phase".
Tests: +4 (404, full clear + playlist preserved + future cancelled, no-future
path, exception -> 500). Full discovery suite: 179 passed.
web_server.py: -100 lines.
Fourth cluster: get_<source>_discovery_status (all eight sources, Beatport
included) -> core.discovery.endpoints.get_discovery_status(states, key, *,
not_found_message, error_label), wired via _get_source_discovery_status.
Unlike sync-status, the discovery-status response shape is byte-identical
across every source (phase/status/progress/spotify_matches/spotify_total/
results/complete), so Beatport folds in here too. Only the 404 string
("... discovery not found" vs "... playlist not found" vs "Beatport chart
not found") and the except-log label vary. ListenBrainz key via _lb_state_key.
NOT touched this cluster: get_*_playlist_state (the sibling endpoints).
Those genuinely diverge per source — different id-key name (playlist_id /
url_hash / playlist_mbid), presence of url / created_at / download_process_id,
Tidal's playlist.__dict__ serialization, and YouTube's strict (non-.get)
field access. Folding them would need a flag pile that wouldn't be a clean
1:1, so they keep their own bodies.
Tests: +4 (404, full response + last_accessed bump, complete=False when not
'discovered', missing-field -> 500). Full discovery suite: 175 passed.
web_server.py: -155 lines.
Third cluster: the get_<source>_sync_status routes (Tidal, Deezer, Qobuz,
Spotify-Public, iTunes-Link, YouTube, ListenBrainz) -> core.discovery.
endpoints.get_sync_status(...), wired via _get_source_sync_status glue.
This cluster carries the real per-source quirks, all captured 1:1 as params:
- not_found_message (iTunes-Link uses "iTunes Link not found").
- error_label vs activity_subject — these DIFFER for Spotify-Public: the
activity feed says "Spotify Link playlist ..." while the except log says
"Error getting Spotify Public sync status".
- playlist-name accessor, three styles lifted verbatim as named helpers:
playlist_name_attr_or_unknown (Tidal: object .name), playlist_name_strict
(Deezer/Qobuz/Spotify-Public/iTunes: state['playlist']['name'], can raise),
playlist_name_safe (YouTube/ListenBrainz: .get default). The strict getter
preserves the original's behavior of raising -> 500 AFTER phase/sync_progress
were already mutated.
- ListenBrainz key via _lb_state_key (caller-resolved).
Beatport stays separate (different payload: status not sync_status, sync_id,
no lock, chart key).
Tests: +9 (3 name accessors incl. raise/fallback semantics; status 404s,
running-no-mutation, finished+activity, error+revert+activity, and strict-
getter-missing -> 500 after partial mutation). Full discovery suite: 171 passed.
web_server.py: -244 lines.
First cluster of the per-source playlist-discovery deduplication. The
convert_<source>_results_to_spotify_tracks functions (Tidal, Deezer, Qobuz,
Spotify-Public, YouTube, ListenBrainz) plus the already-generic
_convert_link_results_to_spotify_tracks were byte-identical apart from the
source label used in their log line.
Lift the shared body into core/discovery/endpoints.py as
convert_results_to_spotify_tracks(results, source_label); the 7 web_server
functions become 1-line delegations (names/signatures unchanged, so all
callers and behavior are identical — 1:1).
Beatport is intentionally NOT folded in: its converter coerces artist
objects to strings and emits a different track shape (source field, album
dict), so it keeps its own implementation.
Tests: tests/discovery/test_discovery_endpoints.py (12) pin both input
shapes (manual spotify_data / auto spotify_track+found), optional
track/disc numbers, falsy-0 omission, field defaults, skip-on-neither,
order preservation, if/elif precedence, empty input.
web_server.py: -209 lines. Full discovery suite: 151 passed.
