fix(native): guard librespot paths by sink owner - #534
Conversation
Every hand-over of the sink away from librespot now pauses it and clears the native play intent, so a backend rebuild under another source comes back idle. A queued track from another source claims the sink for its download. Two owner predicates guard the native recovery, restore, watchdog, end-of-track, shuffle-session and device-transfer paths, and a queue whose output device is gone stops without a Spotify resume.

🗄️ Data Integrity & Integration | 🟡 Minor | ⚡ Quick winClear the Spotify queue slot during external transfer.
The external transfer success branch calls
clear_native_playback_recovery(), which does not clearqueue_now. A direct CLI transfer reaches this branch throughhandle_network_event. If a Spotify queue slot is published, the slot can remain the playback owner after playback moves to the external device, leaving stale UI and transport routing.Use
clear_native_recovery_intent_for_external_playbackin this branch, while preservingnative_playback_origin = None. Add a regression test for a Spotify queue slot.🤖 Prompt for AI Agents

immediately before loading or re-arming playback. In

native_context_should_drive after the async fetch and before
load_session_tracks; abort without loading if ownership changed. In
resume_native_shuffle_session, revalidate ownership before
set_native_playback_intent and the subsequent native load, and avoid re-arming
intent when the check fails. Add coverage for ownership changes during both
async gaps.
- Around line 397-401: Reorder the conditions in the native shuffle handler so
the !drive check returns Action::Nothing before the incomplete-fetch branch can
assign session.shuffled. Preserve the existing update for driven sessions, and
add coverage for fetch_complete == false with native_context_should_drive() ==
false to verify the session remains unchanged.

The play intent is now set in the same App lock as the owner check, so no gap sits between the check and the load. A test pins that a shuffle toggle during the context fetch is recorded under another owner.

Summary
While Local Files, Subsonic, Internet Radio, YouTube or Qobuz played, the paused Spotify session could still act. A reconnect restored the old Spotify track over the source, the load watchdog rebuilt the player, a late end-of-track event skipped the audible track, the shuffle session moved or reloaded at the other source's position, and a transfer to an external device started a second player. This PR makes every native path ask who owns the sink. It changes no lifecycle: librespot is still only paused, never shut down.
What changed:
App::pause_native_playback, which also clears the native play intent. A rebuild under another owner now comes back idle. The two paths that load librespot again (play_queued_spotify, the shuffled queue resume) re-arm the intent, because the stall watchdog disarms on a false intent.App::native_should_drive()andApp::native_context_should_drive(), guard the recovery request, the parked start replay, both watchdogs, the end-of-track handler and its continuation, the restore, the idle device reconcile, the recovery routes and the stray-Playingguard, which knew only the queue before. The rebuild itself is never refused: every sender removes the player before it sends, so a refusal there loses the backend.resume_or_finishtakes the reason the queue ended. A lost output device resumes nothing. A decoded queue slot no longer preloads the next Spotify track.Shuffleis refused under a queue slot, likeRepeat.Action::TransferPlaybackgoes through the newApp::transfer_playback_to_device.Deliberate behaviour changes a user can see:
Playingevent from librespot under another source (a remote Connect client that presses play on the spotatui device, for example) is paused again at once. Spotify takes the output back only through a start inside spotatui.Testing

They ship covered by inspection, and I do a live Spotify-plus-Qobuz pass before the merge.Additional notes
Not run: the Linux
all-sourcestest leg and the macOS job. CI runs both.The change is larger than usual (+868/-208) because the release sites, the predicates and the queue claim share the same five dispatchers and only make sense together. More than half of the added lines are tests.
