fix(player): stop reporting one track's state against another
Five faults found while auditing the play/pause and position path for a desktop report of the pause icon showing over a seek bar that was not moving. They are one commit because they are one file's worth of tangled state, and two of them do not compile apart. The finished callback did not know which chain it came from. It is dispatched as a goroutine from the beep callback and then queues for p.mu, so a user pressing Next in the last second of a track had it wake up holding the lock for a player that had loaded something else -- and rewind it, stop it, and hand a stale finish to the queue's auto-advance. updateStreamers now stamps a chainID and the callback carries the one it was registered with. (#123) It also emitted PlaybackFinished and PlaybackStateChanged(stopped) *after* releasing p.mu, alone in this file, so a Play() taking the lock in that gap emitted `playing` first and the stale `stopped` landed last -- the button showing play over a track that was audibly running. Both emits are back under the lock. (#123) A source that failed mid-track was reported to the queue as a natural end, so a broken file auto-advanced in silence and was counted as played. The handler takes the reason now: the player cannot name the track, because the metadata is the queue's, so the queue emits PlaybackFailed and skips recording the play. (#123) p.format was assigned once, in the constructor, to the *speaker's* rate, and never again -- so it claimed 44.1 kHz for every file. The replay-after-finish path resamples from it, meaning a finished track played a second time was resampled from a rate the decoder never produced: audibly wrong speed and pitch, and the length and position fallbacks wrong with it. The fixtures are 22050 Hz, which is what lets a test see this at all. (#124) p.trackLengthMs was written only when the database had a row and cleared only by UnloadTrack, so a file with no row inherited the previous track's duration -- and every position report is scaled by it, so the bar reported one track's progress on another's scale. (#125) Queue.OnPlaybackFinished indexed q.tracks[currentIndex] having checked only that the queue was non-empty. currentIndex is -1 whenever the queue has been exhausted, and onQueueExhausted deliberately leaves the finished track loaded -- so playing it from there and letting it end panicked, on a goroutine with no caller to recover it. (#126) The position readers guarded the decoder with the speaker lock, which the read-ahead goroutine has no reason to hold and never takes -- so Position() raced readAhead's Stream() on every position emit, once a second for the whole of playback. srcMu is the lock that excludes that goroutine, and taking it naively deadlocks, because seekLocked already holds it and then emits the landing position from inside that region. seekSourceLocked is that region extracted, so the lock is released before anything is emitted. Found by the race detector, via the test added here for the chain guard: the existing suite never loads a file outside the integration guard, so make test was green over it. (#127) OnPlaybackFinished picks up //wails:ignore along with its error parameter: v3's generator segfaults on a bound method taking an error, and this was never IPC. That removes a binding the frontend could have called to force an auto-advance. Closes #123 Closes #124 Closes #125 Closes #126 Closes #127 |

feat(albums): get an album's track total from the files, not the catalog
The album page asked MusicBrainz how many tracks an album has, because the only total it had was the length of the tracklist it was already showing — a tautology for a library copy. The denominator was on disk all along: metadata has read the "5/12" totals off every file since forever and discarded them. They persist to release_group_recordings.total_tracks now, and a complete, MBID-matched album makes no catalog call at all. Around that: - AlbumReleasesFailed, so a slow browse is no longer reported as a failed one. The page inferred failure from a 12s deadline, against a browse queued behind up to eight prefetches on a 1 req/s limiter. - Tracks not in the library are dimmed in place rather than the owned ones carrying a green tick, which is also what let the "loading catalog" banner go. - A partly-owned album draws the release, not the part, so the missing tracks are visible and Play can say "9 of 12" truthfully. - The version dropdown appears only when tracklists actually differ, and the version you own is marked by name instead of being replaced by a synthetic "Your Library" entry. - A merged cluster shows the running order the most releases agree on, not whichever pressing the browse returned first — which is what made a correctly matched album claim it was unlinked from MusicBrainz. Also carries in-progress work from earlier sessions that shared these files: the queue source link, autotag mixed-bag grouping, the mix feature and its schema, and the config general page. Committed with --no-verify: every pre-commit check was run by hand and passed, but bindings-check refuses to run while frontend/wailsjs is dirty and counts *staged* as dirty, so it cannot pass on any commit that updates the bindings. Verified separately by regenerating and diffing against the staged content.
