Real-world wishlist case the original c3b88e69 design missed: user with
26 missing tracks from 26 different albums. Each item used to promote
to its own album-bundle sub-batch (``min_tracks_per_album=1``), which
downloaded the ENTIRE album (5-42 files) to claim one track. Confirmed
in app.log:
- "Licensed To Ill" downloaded 3 times across cycles (3-4 files each)
- "The Understanding" 17 files for 1 wishlist track
- "Alright, Still" 42 files for 1 wishlist track
- ~85% wasted bandwidth, slskd hammered with 26 concurrent searches
PR 1 of a 4-PR fix series — see commit body footer for the other PRs.
Default ``min_tracks_per_album`` 1 → 2. Single-track wishlist items
fall to ``residual_tracks`` → classic per-track batch (already works,
already efficient). Album-bundle kept for the case it was designed
for: user has 2+ tracks missing from the same album.
Override via the new ``wishlist.album_bundle_min_tracks`` config key:
- 1 = previous behaviour (bundle every item)
- 2 = new default
- 3+ = stricter, for users who want bundle only on bigger gaps
Helper ``_resolve_album_bundle_threshold`` lives in
``core/wishlist/processing.py``. Defensive shape mirrors the existing
config-driven knobs (``get_poll_interval`` / ``get_transient_miss_threshold``):
non-numeric, non-positive, or config-manager-raise all fall back to
the safe default. Three test cases pin the fallback chain.
Both wishlist entry points wired through the same helper:
- ``process_wishlist_automatically`` (auto cycle, line 812)
- ``start_manual_wishlist_download_batch`` (manual run, line 539)
Tests:
- ``tests/wishlist/test_album_grouping.py`` — old ``test_default_threshold_promotes_solo_albums`` flipped to ``test_default_threshold_demotes_solo_albums`` with explanatory docstring naming the real-world cause. New ``test_default_threshold_promotes_multi_track_albums`` pins the 2+ promotion. New ``test_explicit_threshold_one_restores_solo_promotion`` pins that the kwarg still works for opt-back-in.
- ``tests/wishlist/test_processing.py`` — 3 new tests for ``_resolve_album_bundle_threshold``: default-when-config-missing, honors-config-override, falls-back-on-garbage.
- ``tests/wishlist/test_automation.py`` — ``test_wishlist_albums_cycle_splits_into_per_album_batches`` updated to use 2+ tracks per album (5 tracks across 2 albums instead of 3 across 2 with 1 solo). ``test_wishlist_albums_cycle_residual_for_orphan_tracks`` updated to include 2 tracks from Album One so it still promotes.
- ``tests/wishlist/test_manual_download.py`` — same shape update for the manual path test.
- ``tests/wishlist/test_album_grouping.py:test_multiple_albums_emit_separate_groups`` updated to reflect new default (alb1 with 2 tracks promotes, alb2 with 1 track goes residual).
- ``tests/wishlist/test_album_grouping.py:test_nested_track_data_payloads_normalized`` pinned with explicit ``min_tracks_per_album=1`` so the test stays focused on payload-shape parsing, not the threshold rule.
114 wishlist tests pass; 866 across wishlist + automation + downloads +
album_bundle + album_bundle_dispatch suites still green. Ruff clean.
Sibling PRs queued in TaskCreate:
- PR 2 — investigate post-process staging-match miss (the second-order
bug that causes the same album to redownload every cycle when the
staging step doesn't claim the requested track).
- PR 3 — fix sibling-completion gate that fires on first sibling
instead of last (log evidence: run a4945c88 finalized 1/26 batches).
- PR 4 — UI distinguish Queued from Analyzing for batches waiting
on the executor (23/26 batches sit at "Analyzing..." while really
queued at max_workers=3).
Phase 1c.2.1 splits each wishlist invocation into per-album sub-
batches so the album-bundle dispatch can engage once per album.
Side effect: the completion handler ``finalize_auto_wishlist_completion``
ran end-of-run logic (cycle toggle + state reset + automation
event emit) once per BATCH, so a 2-album run fired the cycle
toggle twice + emitted two ``wishlist_processing_completed``
events. The cycle landed at the right value either way but the
state machine had become per-batch instead of per-run.
Fix: reify "wishlist run" as a first-class concept via a shared
``wishlist_run_id`` UUID. Generated once per wishlist invocation
in both the auto- and manual-wishlist paths, stamped on every
sub-batch row in ``download_batches``.
``finalize_auto_wishlist_completion`` now reads the completing
batch's ``wishlist_run_id`` and, when present, scans
``download_batches`` for siblings still in pre-terminal phases.
If any sibling is still active, the per-batch summary records
but the cycle toggle + state reset + automation emit are
deferred. Only the last completing sibling fires the run-level
finalization. Legacy single-batch runs (no run_id field) keep
their toggle-immediately behavior — back-compat by absence.
The run_id also lays groundwork for frontend grouping (one
logical row in the Downloads view per wishlist run instead of N
sibling rows), but that UX work is deferred.
3 new tests in ``test_processing.py`` pin: defer-when-siblings-
active, toggle-when-last-sibling-done, back-compat-without-run_id.
1 new assertion in ``test_automation.py`` confirms all sub-batches
of one auto-wishlist invocation share the same run_id. 309 tests
across wishlist + automation suites green.
Notes: dispatch concurrency unchanged — sub-batches still run via
the shared download worker pool. Slskd serializes per-uploader at
its own layer (same uploader = automatic queue, different
uploaders = legit parallel), so SoulSync-side serial enforcement
would duplicate work the right layer already handles.
Root cause (#700): the Soulseek album-bundle path downloads whole
releases into a private staging dir, then per-track workers claim
those files via the staging-match shortcut. When slskd files arrived
without ID3 tags (common for FLAC rips), the staging cache fell back
to the filename stem as the title — and stems shaped like
"Artist - Album - 03 - Title" could not clear the 0.80 title-
similarity threshold against the clean Spotify track name. Every
track in the album went not_found, the batch ended "failed" in the
Downloads UI with an empty queue, and the bundle-downloaded files
just sat unused in staging.
Fix: in _staging_title_variants, add a trailing-title variant by
extracting the segments after a bare track-number block (e.g. "03")
between " - " delimiters. Conservative — only fires when a clear
digit segment is present, so real song titles with dashes like
"Hold Me - Live" are left intact. Generated as an additional variant
alongside the existing raw/compacted/feat-stripped/bonus-stripped
forms, so behavior on already-matching files is unchanged.
Downstream (#698): the album-bundle staging miss pushed every failed
track to the wishlist labelled as a playlist track, and a couple of
fallback paths in ensure_wishlist_track_format and the slskd-result
reconstruction hardcoded album_type='single' / total_tracks=1 on the
stored album dict. On wishlist requeue the path builder saw
album_type='single' and routed the download through single_path,
dumping the file in the Singles tree even though it belonged to an
album. (Running Reorganize would fix it because the DB album linkage
was still correct, but the file landed in the wrong place first.)
Fixes:
- new resolve_wishlist_source_type_for_batch() returns 'album' for
is_album_download batches; wishlist_failed.py now calls it instead
of hardcoding 'playlist'
- build_wishlist_source_context() threads album_context /
artist_context / is_album_download from the batch into the wishlist
row so future requeue logic has authoritative routing data
- the non-dict-album fallback in ensure_wishlist_track_format and
the slskd-result reconstruction default album_type='album' (and
total_tracks=0 = unknown) instead of lying with 'single'/1; the
existing setdefault chain handles dict-shaped album data unchanged
Tests:
- 2 staging-match tests pin the new tail-extraction behavior against
a realistic untagged slskd stem, plus a negative test that confirms
a dash-in-title without a digit segment still does NOT extract a
variant
- 2 payload tests pin the album_type='album' default for both
fallback paths
- 4 processing tests pin resolve_wishlist_source_type_for_batch()
and the album-context threading in build_wishlist_source_context()
3974 pass; no behavioural change on already-working flows.
Manual matches can be created from sync history as mirrored while wishlist and download flows later see the same track as wishlist or a provider source. Add a shared track-level lookup that falls back from exact source/id to source_track_id and title/artist, then use it for wishlist adds, cleanup, and download analysis so mapped tracks are not re-added or redownloaded.
Add coverage for mirrored-source matches being honored by wishlist cleanup and download batches, including the internal wishlist force-download path.
- add direct service and presence coverage
- pin resolver, processing, route, and payload edge cases
- keep wishlist package extraction safe for future refactors
- add core/wishlist as the home for wishlist payload, resolution, state, processing, reporting, and selection helpers
- move wishlist-specific tests into tests/wishlist alongside the new package layout
- keep web_server.py and the import/search callers as thin adapters for now
