Follow-up to the personalized-playlists standardization PR. New
`personalized_pipeline` automation action syncs selected discover-
page playlists (Hidden Gems / Discovery Shuffle / Time Machine /
Genre / Daily Mix / Fresh Tape / The Archives / Seasonal Mix) to
the active media server + queues missing tracks for download.
Same pattern as the existing mirrored `playlist_pipeline` but two
phases instead of four — no REFRESH (no external source to re-pull)
and no DISCOVER (manager-backed snapshots are already metadata-
matched). Pipeline shape:
SNAPSHOT → SYNC → WISHLIST
Where SNAPSHOT either reads the persisted track list from
`PersonalizedPlaylistManager` (default) or refreshes it first when
`refresh_first=true` (cron use case: regenerate Hidden Gems nightly
and sync the fresh set).
Shared helper extraction:
PHASE 3 (SYNC loop) + PHASE 4 (WISHLIST tail) lifted out of mirrored
`playlist_pipeline` into `core/automation/handlers/_pipeline_shared.py`
as `run_sync_and_wishlist(deps, automation_id, playlists, sync_one_fn,
sync_id_for_fn, ...)`. Both pipelines call it. Mirrored injects
`auto_sync_playlist` as the per-playlist sync function; personalized
injects a thin wrapper that launches `_run_sync_task` directly with
a pre-built tracks_json. Same sync-state polling / progress emission
/ status counting / wishlist trigger logic — 0 duplication.
Files added:
- core/automation/handlers/_pipeline_shared.py
- core/automation/handlers/personalized_pipeline.py
- tests/automation/test_handlers_personalized_pipeline.py
Files changed:
- core/automation/handlers/playlist_pipeline.py: PHASE 3+4 replaced
with shared helper call (~100 lines deleted, 1 helper invocation
added; behavior identical).
- core/automation/deps.py: new `build_personalized_manager` field
(lazy builder so the pipeline gets a fresh PersonalizedPlaylistManager
per run).
- core/automation/handlers/__init__.py + registration.py: register
`personalized_pipeline` action with the shared `pipeline_running`
guard so it can't overlap mirrored.
- core/automation/blocks.py: new `personalized_pipeline` block
declaration with config_fields (kinds multi-select, refresh_first,
skip_wishlist).
- web_server.py: thread `_build_personalized_manager` into
AutomationDeps construction.
- All 5 automation test fixtures: `_build_deps` adds
`build_personalized_manager=lambda: None` stub.
- tests/automation/test_handler_registration.py:
EXPECTED_ACTION_NAMES + EXPECTED_GUARDED_ACTIONS gain
`personalized_pipeline`.
Trigger schema:
{
"_automation_id": "...",
"kinds": [
{"kind": "hidden_gems"},
{"kind": "time_machine", "variant": "1980s"},
{"kind": "seasonal_mix", "variant": "halloween"}
],
"refresh_first": false,
"skip_wishlist": false
}
Tests (14 new, 178 automation total):
- _track_to_sync_shape: basic shape, source ID fallback chain,
no-id returns empty string
- empty config / non-list kinds / empty kinds list all return
error + clear pipeline_running flag
- _build_payloads_for_kinds: skips invalid entries, skips kinds
with no tracks, refresh_first vs ensure dispatch, payload shape
+ sync_id format, manager exception swallowed continues
- _sync_personalized_playlist: launches background thread + returns
status='started'
- happy path: stubbed sync_states drives helper to completion, flag
cleaned up
Full suite: 3383 passed.
Note: the trigger UI block declares config_fields but the frontend
doesn't yet render the `personalized_playlist_select` multi-select
type — usable today via API; polished UI ships in a follow-up
frontend PR.
