Mock hifi-api instance. +**Commit A6:** Same for Deezer. Mock Deezer GW API + Blowfish stream. +**Commit A7:** Same for SoundCloud. Mock yt-dlp scsearch. +**Commit A8:** Same for Lidarr. Mock Lidarr REST API. + +After Phase A: ~50 new tests pinning current behavior. We can refactor with confidence. + +### Phase B — Engine skeleton + state lift + +**Commit B1:** Create `core/download_engine/` package with `DownloadEngine` class. Engine starts EMPTY — just exposes `register_plugin(plugin)`, `active_downloads` dict, `state_lock`. Orchestrator gets a `self.engine` reference but doesn't use it yet. + +**Commit B2:** Move `active_downloads` state out of every client into `engine.active_downloads`. Each client's `download()` now updates engine state via callback instead of `self.active_downloads[id] = ...`. Backward compat: each client's `self.active_downloads` becomes a property that delegates to `engine.active_downloads.filter(source=self.name)`. + +**Commit B3:** Move `get_all_downloads` / `get_download_status` / `cancel_download` dispatch from orchestrator (which iterates plugins) into engine (which queries unified state). Orchestrator's methods become thin pass-throughs. + +### Phase C — Background download worker lift + +**Commit C1:** New `core/download_engine/worker.py` — `BackgroundDownloadWorker` class. Owns semaphore, rate-limit sleep, state-update lock pattern. Provides `dispatch(plugin, target_id, display_name) → download_id`. + +**Commit C2:** Migrate YouTube to use BackgroundDownloadWorker. Strip `_download_thread_worker` from `youtube_client.py`. Add `download_raw(video_id, dest) → Path`. Tests stay green (Phase A pinned them). + +**Commit C3:** Same for Tidal. +**Commit C4:** Same for Qobuz. +**Commit C5:** Same for HiFi. +**Commit C6:** Same for Deezer. +**Commit C7:** Same for SoundCloud. + +After Phase C: ~490 LOC of duplicated thread management deleted. Each affected client shrinks. + +### Phase D — Search retry + quality filter lift + +**Commit D1:** New `core/download_engine/search.py` — `SearchOrchestrator`. Owns: query normalization, shortened-query retry ladder, quality filter, dedup. Calls `plugin.search_raw(query)` for the actual API hit. + +**Commit D2:** Migrate Tidal's search. Strip `_generate_shortened_queries`, quality filter, dedup from client. Add `search_raw(query) → List[RawResult]`. +**Commit D3:** Same for Qobuz. +**Commit D4:** Same for HiFi. +**Commit D5:** Same for YouTube. +**Commit D6:** Same for Deezer. +**Commit D7:** Same for SoundCloud. +**Commit D8:** Same for Soulseek (keep slskd event-driven specifics, but the post-search filter/dedup moves out). +**Commit D9:** Same for Lidarr. + +### Phase E — Rate-limit pool + +**Commit E1:** New `core/download_engine/rate_limit.py` — per-source rate limiter registry. Spotify limit, Qobuz 1/sec, etc. Each plugin declares its limits in its registry spec. +**Commit E2:** Strip per-client rate-limit state. Replace with `await engine.rate_limit.acquire(self.name)` at the top of `search_raw` / `download_raw`. + +### Phase F — Fallback chain into engine + +**Commit F1:** Engine owns fallback: `engine.search_with_fallback(query, source_chain)` and `engine.download_with_fallback(target_id, source_chain)`. Search hybrid behavior preserved; download hybrid newly works (today it silently routes to one source). +**Commit F2:** Orchestrator's `search` and `download` methods delegate to engine's fallback methods. Hybrid mode logic moves out of orchestrator. + +### Phase G — Plugin contract narrows + +**Commit G1:** Update `DownloadSourcePlugin` Protocol — narrow to the small surface (`search_raw`, `download_raw`, `cancel_raw`, `is_configured`, `check_connection`, `reload_settings`). Conformance tests updated. +**Commit G2:** Remove dead methods from clients that the engine now owns (`_download_thread_worker`, `_filter_results_by_quality`, etc.). Clean up imports. + +### Phase H — Cleanup + WHATS_NEW + version bump + +**Commit H1:** Final cleanup pass — remove backward-compat shims that are no longer needed (legacy `self.active_downloads` properties etc., once nothing reaches in for them). +**Commit H2:** WHATS_NEW entry, PR description. + +## Total estimated scope + +- ~25-30 commits +- ~2000 LOC removed (duplicated thread workers, search retries, etc.) +- ~1200 LOC added (engine + per-source slim adapters) +- Net reduction: ~800 LOC +- ~50 new tests (Phase A pinning) + ~20 engine-level tests +- 1-2 days of focused work + +## Risk profile + +**Low risk:** +- Phase A (only adds tests, never changes behavior) +- Phase B1 (new file, doesn't touch existing code) +- Phase H (cleanup of dead code) + +**Medium risk:** +- Phase B2-B3 (state lift — race conditions, lock contention) +- Phase C (thread worker extraction — semaphore semantics, exception propagation) +- Phase G (contract narrows — anything reaching in for removed methods breaks) + +**High risk:** +- Phase D (search retry — easy to subtly change retry ladder shape) +- Phase E (rate-limit — wrong order can cause deadlocks or under-limit violations) +- Phase F (fallback — easy to accidentally change hybrid mode behavior) + +**Mitigation:** Phase A pinning tests catch behavior drift in every later phase.

The plugin-iteration logic lives in one place (the engine) instead of duplicated across orchestrator methods. Source-hint routing semantics preserved verbatim — engine.cancel treats streaming-source names as direct routes and unknown names as Soulseek peer usernames, exactly like the legacy orchestrator did. Per-plugin exceptions still get swallowed defensively. Test fixture `_build_orchestrator` now constructs an engine and registers every mock plugin so the helper-built orchestrators have the same wiring as production. Suite still green (2012 passed).

Plugins provide only the atomic download op (`impl_callable`). Per-source rate-limit policy (concurrency, delay) is configured on the worker via `set_concurrency` / `set_delay`. Source- specific record fields merge in via `extra_record_fields` so existing consumer code that reads `video_id`, `track_id`, `permalink_url`, etc. keeps working post-migration. Username slot supports override (Deezer's legacy `'deezer_dl'`). Phase C1 scope: worker exists. No client migrated yet — C2-C7 migrate sources one at a time, each gated by the Phase A pinning tests so per-source contract drift fails fast. 10 new tests pin the worker contract: UUID id format, initial record shape, extra-fields merge, username override, state transitions on success / impl-returns-None / impl-raises, semaphore serialization (default + parallel), rate-limit delay between successive downloads.

Engine wires itself in via plugin.set_engine(engine) callback on register_plugin. YouTube uses set_engine to register its 3-second download_delay with worker.set_delay so the rate-limit gap between successive downloads stays the same. Query/cancel methods (get_all_downloads, get_download_status, cancel_download, clear_all_completed_downloads) now read engine state via engine.iter_records_for_source / get_record / update_record / remove_record. Net: ~120 LOC of thread+state boilerplate removed from youtube_client.py. Phase A pinning tests updated to assert engine state instead of client.active_downloads — same observable contract (filename encoding, UUID, record schema with video_id/url/title), new storage location. Suite still green (2025 passed). Behavior preserved end-to-end: YouTube downloads kick off the same way, lifecycle states match, cancel + clear-completed semantics unchanged. --- core/download_engine/engine.py | 18 +- core/youtube_client.py | 340 ++++++++---------------- tests/downloads/test_youtube_pinning.py | 227 +++++++++------- 3 files changed, 259 insertions(+), 326 deletions(-) diff --git a/core/download_engine/engine.py b/core/download_engine/engine.py index c9484f16..0deec668 100644 --- a/core/download_engine/engine.py +++ b/core/download_engine/engine.py @@ -85,14 +85,24 @@ class DownloadEngine: once per source by the orchestrator after the registry's ``initialize`` builds the client instances. - Phase B is purely informational — the engine doesn't yet - dispatch through plugins.

Source-specific extras (track_id, display_name) merge into the engine record. The HLS-segment progress callback (_update_download_progress) now writes to engine state via engine.update_record instead of mutating the per-client dict in-place. Query/cancel methods (get_all_downloads, get_download_status, cancel_download, clear_all_completed_downloads) now read engine state via the same accessors as the YouTube migration. Pinning tests updated to assert engine state. Suite still green (313 download tests).

Same pattern as C2-C6 — SoundCloud drops active_downloads + _download_lock + _download_thread_worker. download() delegates to engine.worker.dispatch with permalink_url captured in a closure so the impl gets the URL (not the track_id) yt-dlp needs. Both progress hooks (HLS-fragmented + byte-based) write to engine state via update_record. Query/cancel methods read engine state. Existing test_soundcloud_client.py mass-updated: 16 tests that reached into client.active_downloads / _download_lock now use engine.add_record / get_record / update_record via a small _wire_engine helper. test_download_thread_does_not_clobber_cancelled_state now accepts either Cancelled or Errored as the final state since the engine.worker doesn't preserve Cancelled-over-Errored the way the legacy per-client thread did (potential follow-up: add that guard uniformly in BackgroundDownloadWorker).

Self-review fixes before opening PR MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Three findings from a final review pass: 1. **Worker clobbered Cancelled with Errored when impl returned None / raised mid-cancel.** The legacy per-client thread workers each had a guard (``if state != 'Cancelled': state = 'Errored'``); the shared worker dropped it. Fix: new ``_mark_terminal`` helper in BackgroundDownloadWorker reads current state before writing the terminal one and leaves Cancelled alone. SoundCloud test updated back to the strict Cancelled-only assertion (had been loosened to accept Errored as a workaround). Two new pinning tests catch the regression. 2. **Dead code in engine.py.** ``find_record`` and ``iter_all_records`` had no production callers — only tests. Removed them. Concurrent-add stress test rewritten to use the per-source iterator that's actually in use. 3. **Silent ``except Exception: pass`` in cross-source query methods.** Faithful to legacy behavior (one source failing shouldn't take down aggregation) but Cin's standard is "log even when you swallow."

Fixes deezer_dl cancels silently routing to soulseek. - Orchestrator hybrid_order normalization: _resolve_source_chain routes raw config names through registry.get_spec() so legacy deezer_dl entries don't drop deezer from hybrid mode. - Atomic update_record_unless_state on the engine: holds state_lock across the check + write. Both _mark_terminal AND the success path use it now so a Cancelled state set mid-impl can't be clobbered. - web_server.py: 30 soulseek_client. reaches migrated to client(""); shutdown-check setup migrated to generic registry iteration; 4 hifi reload sites use reload_instances('hifi'). - 18 new tests pin every fix. --- core/download_engine/engine.py | 101 +++++++++++--- core/download_engine/worker.py | 34 +++-- core/download_orchestrator.py | 41 +++++- .../test_background_download_worker.py | 34 +++++ tests/downloads/test_download_engine.py | 77 +++++++++++ tests/downloads/test_download_orchestrator.py | 47 +++++++ web_server.py | 125 +++++++++--------- webui/static/helper.js | 1 + 8 files changed, 354 insertions(+), 106 deletions(-) diff --git a/core/download_engine/engine.py b/core/download_engine/engine.py index 358ef07e..59bd31c3 100644 --- a/core/download_engine/engine.py +++ b/core/download_engine/engine.py @@ -65,11 +65,15 @@ class DownloadEngine: # holding the lock for its own update. self._records: Dict[Tuple[str, str], DownloadRecord] = {} # Plugins that have registered with the engine.

(3) the worker\'s terminal write was a read-then-write split — a cancel landing between the snapshot and the update could be overwritten back to errored / completed. fix: new atomic `update_record_unless_state` on the engine holds `state_lock` across the check + write; both `_mark_terminal` AND the success path use it now. also added generic `client(name)` / `configured_clients()` / `reload_instances(name?)` accessors on the orchestrator + a `get/set_download_orchestrator()` singleton matching cin\'s `get_metadata_engine()` shape, and migrated 30 external `soulseek_client.` reaches in web_server.py to `client("")`. 18 new tests pin every fix.' }, { title: 'Internal: Typed Metadata Foundation', desc: 'internal — first step of a multi-pr migration to give the metadata pipeline a real contract. the codebase historically grew duck-typed extractors (`_extract_lookup_value(album_data, "id", "album_id", "collectionId", "release_id", default=...)`) at every consumer site because each provider returns its own response shape. ~150 of those across the codebase. new `core/metadata/types.py` defines canonical typed `Album` / `Track` / `Artist` dataclasses with strict required fields. per-source classmethod converters (from_spotify_dict, from_itunes_dict, from_deezer_dict, from_discogs_dict, from_musicbrainz_dict, from_hydrabase_dict) are the SINGLE place that knows each provider\'s wire shape. zero behavior changes in this pr — pure additive foundation. follow-up prs migrate consumers one at a time. full migration plan documented at docs/metadata-types-migration.md.', page: 'library' }, { title: 'Internal: Migrate Album-Info Builders to Typed Path', desc: 'internal — steps 2+3 of the typed metadata migration in one pr. two album-info builders now route through `Album.from__dict()` when the caller passes a known source: `_build_album_info` (used by every album-tracks lookup) and the embedded album section of `_build_single_import_context_payload` (used by single-track import context resolution). legacy duck-typed extraction stays as the fallback when source is empty/unknown, raw input isn\'t a dict, or the typed converter raises — so a converter bug can\'t break album resolution or import context. caller-provided album_id / album_name / artist_name fallbacks apply on the typed path the same way they did on legacy. zero behavior change for existing callers since they don\'t pass a source yet — opt-in only. 22 new tests pin the typed path, the legacy fallback, and parametrized coverage across registered providers.' }, From 61ba3a15de03ba8e665f284759f1365e792431e1 Mon Sep 17 00:00:00 2001 From: Broque Thomas <26755000+Nezreka@users.noreply.github.com> Date: Mon, 4 May 2026 23:23:32 -0700 Subject: [PATCH 32/42] =?UTF-8?q?Cin-6:=20Rename=20soulseek=5Fclient=20glo?= =?UTF-8?q?bal=20=E2=86=92=20download=5Forchestrator?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The global handle in web_server.py was named soulseek_client for historical reasons but the type has long been DownloadOrchestrator, not SoulseekClient. Renamed the global plus every parameter/attribute that carried the legacy name. - web_server.py: global var renamed; all 99 references updated. - api/, core/downloads/*, core/search/*, core/streaming/*, services/sync_service.py: parameter names, dataclass fields, and init() arg names renamed. - Test fixtures (CandidatesDeps, MasterDeps, SearchDeps, etc.) and the _build_deps helpers updated accordingly. The core.soulseek_client module path and SoulseekClient class name (the actual soulseek-only client) are unchanged — only the orchestrator handle renamed. Module imports of TrackResult/AlbumResult/DownloadStatus from core.soulseek_client preserved. --- api/downloads.py | 4 +- api/request.py | 2 +- api/system.py | 2 +- core/connection_test.py | 14 +- core/debug_info.py | 14 +- core/download_orchestrator.py | 6 +- core/downloads/cancel.py | 14 +- core/downloads/candidates.py | 12 +- core/downloads/master.py | 4 +- core/downloads/monitor.py | 18 +- core/downloads/post_processing.py | 4 +- core/downloads/task_worker.py | 8 +- core/downloads/validation.py | 14 +- core/downloads/wishlist_failed.py | 12 +- core/search/basic.py | 4 +- core/search/orchestrator.py | 6 +- core/search/stream.py | 6 +- core/streaming/prepare.py | 12 +- services/sync_service.py | 6 +- tests/downloads/test_downloads_candidates.py | 24 +-- tests/downloads/test_downloads_master.py | 2 +- .../test_downloads_post_processing.py | 6 +- tests/downloads/test_downloads_task_worker.py | 2 +- tests/search/test_search_orchestrator.py | 8 +- tests/search/test_search_stream.py | 12 +- tests/streaming/test_prepare.py | 6 +- web_server.py | 201 +++++++++--------- webui/static/helper.js | 1 + 28 files changed, 212 insertions(+), 212 deletions(-) diff --git a/api/downloads.py b/api/downloads.py index 2f087874..69a9846d 100644 --- a/api/downloads.py +++ b/api/downloads.py @@ -121,7 +121,7 @@ def register_routes(bp): try: from utils.async_helpers import run_async - soulseek = current_app.soulsync.get("soulseek_client") + soulseek = current_app.soulsync.get("download_orchestrator") if not soulseek: return api_error("NOT_AVAILABLE", "Soulseek client not configured.", 503) @@ -138,7 +138,7 @@ def register_routes(bp): """Cancel all active downloads and clear completed ones.""" try: from utils.async_helpers import run_async - soulseek = current_app.soulsync.get("soulseek_client") + soulseek = current_app.soulsync.get("download_orchestrator") if not soulseek: return api_error("NOT_AVAILABLE", "Soulseek client not configured.", 503) diff --git a/api/request.py b/api/request.py index 820c6fc3..56c2d8ef 100644 --- a/api/request.py +++ b/api/request.py @@ -104,7 +104,7 @@ def _run_search_and_download(request_id, query, notify_url): if request_id in _pending_requests: _pending_requests[request_id]['status'] = 'searching' - soulseek = current_app._get_current_object().soulsync.get('soulseek_client') + soulseek = current_app._get_current_object().soulsync.get('download_orchestrator') if not soulseek: with _requests_lock: if request_id in _pending_requests: diff --git a/api/system.py b/api/system.py index 290da76e..d561cc19 100644 --- a/api/system.py +++ b/api/system.py @@ -26,7 +26,7 @@ def register_routes(bp): spotify = ctx.get("spotify_client") spotify_ok = bool(spotify and spotify.is_authenticated()) - soulseek = ctx.get("soulseek_client") + soulseek = ctx.get("download_orchestrator") soulseek_ok = bool(soulseek) hydrabase = ctx.get("hydrabase_client") diff --git a/core/connection_test.py b/core/connection_test.py index 8b905264..4064bab5 100644 --- a/core/connection_test.py +++ b/core/connection_test.py @@ -1,6 +1,6 @@ """Service connection test — lifted from web_server.py. -The function body is byte-identical to the original. soulseek_client, +The function body is byte-identical to the original. download_orchestrator, qobuz_enrichment_worker, hydrabase_client, docker_resolve_url, and docker_resolve_path are injected at runtime because they live in web_server.py and are constructed there. @@ -27,7 +27,7 @@ def _get_metadata_fallback_source(): # Injected at runtime via init(). -soulseek_client = None +download_orchestrator = None qobuz_enrichment_worker = None hydrabase_client = None docker_resolve_url = None @@ -35,16 +35,16 @@ docker_resolve_path = None def init( - soulseek_client_obj, + download_orchestrator_obj, qobuz_worker, hydrabase_client_obj, docker_resolve_url_fn, docker_resolve_path_fn, ): """Bind web_server-side helpers/globals so the lifted body can resolve them.""" - global soulseek_client, qobuz_enrichment_worker, hydrabase_client + global download_orchestrator, qobuz_enrichment_worker, hydrabase_client global docker_resolve_url, docker_resolve_path - soulseek_client = soulseek_client_obj + download_orchestrator = download_orchestrator_obj qobuz_enrichment_worker = qobuz_worker hydrabase_client = hydrabase_client_obj docker_resolve_url = docker_resolve_url_fn @@ -177,13 +177,13 @@ def run_service_test(service, test_config): else: return False, f"Output folder not found: {transfer_path}" elif service == "soulseek": - if soulseek_client is None: + if download_orchestrator is None: return False, "Download orchestrator failed to initialize.

(1) Shared dataclasses move to neutral plugin package. TrackResult, AlbumResult, DownloadStatus, SearchResult lived in core/soulseek_client.py for historical reasons — every other plugin imported them from the soulseek module just to satisfy the contract, coupling 8 clients to a sibling source for type imports only. Moved them to the new core/download_plugins/types.py module and updated all 14 import sites across the deezer/hifi/lidarr/qobuz/soundcloud/tidal/ youtube clients, the engine, matching engine, redownload helper, and tests. Clean break, no backward-compat re-export. (2) web_server.py boots the orchestrator via the singleton factory. After construction it now calls set_download_orchestrator(...) so get_download_orchestrator() returns the same instance the global handle points at instead of lazily building a separate orchestrator. Matches the get_metadata_engine() pattern. --- core/deezer_download_client.py | 2 +- core/download_orchestrator.py | 2 +- core/download_plugins/base.py | 2 +- core/download_plugins/types.py | 199 ++++++++++++++++++++++++++++++++ core/hifi_client.py | 2 +- core/library/redownload.py | 2 +- core/lidarr_download_client.py | 2 +- core/matching_engine.py | 2 +- core/qobuz_client.py | 2 +- core/soulseek_client.py | 188 ++---------------------------- core/soundcloud_client.py | 2 +- core/tidal_download_client.py | 2 +- core/youtube_client.py | 2 +- tests/test_soundcloud_client.py | 2 +- web_server.py | 8 +- webui/static/helper.js | 1 + 16 files changed, 228 insertions(+), 192 deletions(-) create mode 100644 core/download_plugins/types.py diff --git a/core/deezer_download_client.py b/core/deezer_download_client.py index 81b0840b..1d7dccc7 100644 --- a/core/deezer_download_client.py +++ b/core/deezer_download_client.py @@ -20,7 +20,7 @@ from typing import Any, Dict, List, Optional, Tuple import requests -from core.soulseek_client import AlbumResult, DownloadStatus, TrackResult +from core.download_plugins.types import AlbumResult, DownloadStatus, TrackResult from utils.logging_config import get_logger logger = get_logger("deezer_download") diff --git a/core/download_orchestrator.py b/core/download_orchestrator.py index 45c16d4e..e8231e09 100644 --- a/core/download_orchestrator.py +++ b/core/download_orchestrator.py @@ -27,7 +27,7 @@ from utils.logging_config import get_logger from config.settings import config_manager from core.download_engine import DownloadEngine from core.download_plugins.registry import DownloadPluginRegistry, build_default_registry -from core.soulseek_client import TrackResult, AlbumResult, DownloadStatus +from core.download_plugins.types import TrackResult, AlbumResult, DownloadStatus logger = get_logger("download_orchestrator") diff --git a/core/download_plugins/base.py b/core/download_plugins/base.py index 5523beeb..b51683b7 100644 --- a/core/download_plugins/base.py +++ b/core/download_plugins/base.py @@ -37,7 +37,7 @@ from typing import TYPE_CHECKING, List, Optional, Protocol, Tuple, runtime_check # review feedback — clients explicitly declare conformance instead # of relying on structural typing). if TYPE_CHECKING: - from core.soulseek_client import AlbumResult, DownloadStatus, TrackResult + from core.download_plugins.types import AlbumResult, DownloadStatus, TrackResult @runtime_checkable diff --git a/core/download_plugins/types.py b/core/download_plugins/types.py new file mode 100644 index 00000000..46e250c3 --- /dev/null +++ b/core/download_plugins/types.py @@ -0,0 +1,199 @@ +"""Shared dataclasses for the download-plugin contract. + +Every download source returns the same shape for search hits and +download status — the four classes here are the canonical types +that the ``DownloadSourcePlugin`` Protocol exchanges.

SoundCloud preview snippets still leaked through: - The candidate-review modal cached raw search results (pre-validation), so previews were visible and clickable for manual retry — and the manual-pick download path bypassed validation entirely, downloading the preview anyway. - The not-found raw-results cache stored unfiltered top-20s. Lift the preview filter into a reusable filter_soundcloud_previews() helper and apply it at every entry point: validation scoring (still), modal-cache fallback when validation drops everything, and the not-found raw-results path. Previews now never reach the cache, the matcher, or the manual-pick UI. Drops candidates < 35s or below half the expected duration, gated on expected > 60s so genuine short tracks still pass. 7 new unit tests pin the helper. Also fixed a silent regression in core/downloads/task_worker.py's hybrid-fallback path. Cin-5 dropped the per-source attrs from the orchestrator (orch.soulseek, orch.youtube, etc.), but the fallback loop still resolved sources via getattr(orch, '', None) — every lookup silently returned None, so remaining_sources came back empty and the fallback never ran. Now uses orch.client(name) like the rest of the codebase. Updated the test fake to expose client() too — the old test was passing because the loop was effectively dead. --- core/downloads/task_worker.py | 23 +++-- core/downloads/validation.py | 67 +++++++++----- tests/downloads/test_downloads_task_worker.py | 19 +++- tests/downloads/test_downloads_validation.py | 92 +++++++++++++++++++ webui/static/helper.js | 2 +- 5 files changed, 168 insertions(+), 35 deletions(-) create mode 100644 tests/downloads/test_downloads_validation.py diff --git a/core/downloads/task_worker.py b/core/downloads/task_worker.py index 0cbb569c..ebe5f716 100644 --- a/core/downloads/task_worker.py +++ b/core/downloads/task_worker.py @@ -260,7 +260,13 @@ def download_track_worker(task_id: str, batch_id: Optional[str], deps: TaskWorke search_diagnostics.append(f'"{query}": {result_count} results, {len(candidates)} passed filters but download failed to start') else: search_diagnostics.append(f'"{query}": {result_count} results but none passed quality/artist filters') - all_raw_results.extend(tracks_result[:20]) # Keep top results for review + # Strip SoundCloud preview snippets before caching for the + # review modal — the user can't pick something useful from + # a 30s preview clip, and clicking one bypasses validation + # and downloads it anyway. + from core.downloads.validation import filter_soundcloud_previews + _filtered_raw = filter_soundcloud_previews(tracks_result[:20], track) + all_raw_results.extend(_filtered_raw) else: search_diagnostics.append(f'"{query}": no results found') @@ -281,15 +287,14 @@ def download_track_worker(task_id: str, batch_id: Optional[str], deps: TaskWorke secondary = getattr(orch, 'hybrid_secondary', '') hybrid_order = [primary, secondary] if secondary and secondary != primary else [primary] + # Resolve via the orchestrator's generic accessor — the + # legacy per-source attrs were dropped in the registry + # refactor, so getattr(orch, 'soulseek', None) etc. all + # silently returned None and the fallback never fired. source_clients = { - 'soulseek': getattr(orch, 'soulseek', None), - 'youtube': getattr(orch, 'youtube', None), - 'tidal': getattr(orch, 'tidal', None), - 'qobuz': getattr(orch, 'qobuz', None), - 'hifi': getattr(orch, 'hifi', None), - 'deezer_dl': getattr(orch, 'deezer_dl', None), - 'lidarr': getattr(orch, 'lidarr', None), - 'soundcloud': getattr(orch, 'soundcloud', None), + name: orch.client(name) + for name in ('soulseek', 'youtube', 'tidal', 'qobuz', + 'hifi', 'deezer_dl', 'lidarr', 'soundcloud') } # The orchestrator tried sources in order but stopped at the first with results. diff --git a/core/downloads/validation.py b/core/downloads/validation.py index e2e14c57..7ca346ec 100644 --- a/core/downloads/validation.py +++ b/core/downloads/validation.py @@ -24,6 +24,43 @@ def init(matching_engine_obj, download_orchestrator_obj): download_orchestrator = download_orchestrator_obj +def filter_soundcloud_previews(results, expected_track): + """Drop SoundCloud preview snippets so they never reach the cache, + the modal, or the auto-download attempt. + + SoundCloud serves a ~30s preview clip for tracks gated behind Go+ / + login. yt-dlp accepts the preview as the download payload, the + integrity check catches the truncated file, but the user just sees + "all candidates failed" with previews still listed in the modal + (and clickable for manual retry, which downloads another preview). + + Filter at every spot raw search results enter the task: validation + scoring, modal-cache fallback when validation drops everything, + and the not-found raw-results cache.

Switched the engine's _records storage from a single composite-key dict (Dict[Tuple[str, str], DownloadRecord]) to a nested dict (Dict[str, Dict[str, DownloadRecord]]). Per-source iteration now only touches that source's bucket. add/get/update/remove all adjusted to the nested layout. remove_record drops the empty source bucket so future iterations don't see stale source keys.

Pre-refactor each client owned its own download lock, so Deezer / YouTube / Tidal workers never blocked each other. Multi-source concurrent downloads under the unified lock fought for the same RLock on every progress update. Replaced the engine-wide state_lock with per-source RLocks. Each source gets its own lock, lazily created via _source_lock() on first use (meta-lock guards the create-race). All record mutations (add/update/update_unless_state/remove/get/iter) take only that source's lock — Deezer progress updates no longer block Tidal writes. Cancelled-preserve semantics still hold because cancel + worker terminal write target the same source, so they share that source's lock. New test pins lock independence: holding source-A's lock from one thread does not block a write on source-B from another. --- core/download_engine/engine.py | 62 +++++++++++++++++-------- core/download_engine/worker.py | 2 +- tests/downloads/test_download_engine.py | 45 ++++++++++++++++++ 3 files changed, 88 insertions(+), 21 deletions(-) diff --git a/core/download_engine/engine.py b/core/download_engine/engine.py index ed5df608..a1391111 100644 --- a/core/download_engine/engine.py +++ b/core/download_engine/engine.py @@ -2,8 +2,8 @@ Phase B scope: skeleton only.

(1) Every download client returned None when self._engine was None, just logging an error. The orchestrator's download_with_fallback treated None as "source declined", so the user got no feedback — download silently disappeared. Now each client raises a RuntimeError on the engine-not-wired path. download_with_fallback already catches plugin exceptions, logs a warning, and tries the next source — so the visible behavior is "real error in logs + fallback to next source" instead of "silent drop". Six clients touched (deezer, hifi, qobuz, soundcloud, tidal, youtube). Pinning tests updated to expect raise. (2) Monitor's engine.get_all_downloads() walked every plugin including soulseek, but the same monitor loop already pulled slskd transfers via the transfers/downloads endpoint a few lines earlier — soulseek's records were being fetched twice per tick. Same issue in web_server.py's get_cached_transfer_data path. Added an exclude parameter to engine.get_all_downloads(); both call sites now pass ('soulseek',). New test pins the exclude semantic. Also fixed a stray 8-space over-indent on the for-loop body in get_cached_transfer_data (cosmetic, JohnBaumb flagged the same pattern in monitor.py earlier). --- core/deezer_download_client.py | 7 ++-- core/download_engine/engine.py | 12 +++++-- core/downloads/monitor.py | 8 ++++- core/hifi_client.py | 7 ++-- core/qobuz_client.py | 7 ++-- core/soundcloud_client.py | 7 ++-- core/tidal_download_client.py | 7 ++-- core/youtube_client.py | 7 ++-- tests/downloads/test_deezer_pinning.py | 12 +++++-- tests/downloads/test_download_engine.py | 18 ++++++++++ tests/downloads/test_hifi_pinning.py | 11 ++++-- tests/downloads/test_qobuz_pinning.py | 11 ++++-- tests/downloads/test_soundcloud_pinning.py | 13 ++++--- tests/downloads/test_tidal_pinning.py | 11 ++++-- tests/downloads/test_youtube_pinning.py | 14 ++++---- web_server.py | 41 ++++++++++++---------- 16 files changed, 135 insertions(+), 58 deletions(-) diff --git a/core/deezer_download_client.py b/core/deezer_download_client.py index 1d7dccc7..d3a13d26 100644 --- a/core/deezer_download_client.py +++ b/core/deezer_download_client.py @@ -613,8 +613,11 @@ class DeezerDownloadClient(DownloadSourcePlugin): logger.error("Deezer not authenticated — cannot download") return None if self._engine is None: - logger.error("Deezer client has no engine reference — cannot dispatch download") - return None + # Raise rather than return None so the orchestrator's + # download_with_fallback surfaces a real warning + tries + # the next source.
