Scrobbling can be turned off in Settings (on by default). Now-playing,
scrobbles and stars all go through a ServerActionSink so a persistent
offline outbox can replace the network implementation later without
touching the callers.
Send a now-playing notification when a track starts playing and one
submission once it passes half its duration or four minutes, using the
Subsonic scrobble endpoint's submission and time parameters.
Replaces the per-track `shuffle_order` table and the retained whole-order
arrays with `playback_cursor.shuffleSeed`/`shuffleSize` and a seekable
Feistel permutation of `[0, size)` (`Shuffle.kt`). Positions map through
`flatContext`/`playContext`; a snapshot is shuffled only while the stored
size matches the context, so a stale size is ignored. Queue migration
16->17 adds `shuffleSize` and drops `shuffle_order`.
Drops the "dragging a context row while shuffled reorders the canonical
queue" behaviour: it cannot be made WYSIWYG without materialising the
order. The context is playback-only while shuffled (the view already
disables context drags) and `QueueRepository.move` no-ops for a context
move while shuffled; manual ordering goes through the up-next block.
Removing a context track while shuffled re-derives the permutation at the
smaller size, keeping the same seed and the playhead on the current track,
or on whatever now fills the removed track's slot when it was playing.
Re-anchor the block whenever playback lands on a different context track
(skip, previous, jump, shuffle toggle, restore), so "Up next" always
plays next instead of stranding the block behind a track the listener
has moved past. reanchorFor reports whether the anchor actually moved,
since the current track's combined position can be unchanged even when
the block shifts.
Split playback into a shuffled context and a manual up-next list.
`up_next_entries` holds the same reference-plus-range rows as the
context but is never shuffled; `playback_cursor.upNextAnchor` pins the
block between a context track and its successor. `QueueRepository`
resolves a combined position by mapping through the context order and
splicing the block after the anchor, so the controller's window and
next/previous keep working.
PlaybackController gains addToQueue/playNext, consumes a queued track
when playback advances out of it, resumes the context when the block
empties, and clears the block on a new context. The queue view gets an
editable "Up next" section and a read-only context section, and the
context menu gains Play next / Add to queue for songs, albums and
playlists.
- treat flac/wav/alac as lossless and ignore the bitrate for them, so the declared length never drops below the real encoded size and truncates a lossless transcode
- read the effective stream quality once per media item and use it for both the URL and the clip, closing the window where they disagreed
- honour a bounded DataSpec length in KnownLengthDataSource and reject non-positive length fragments
- drop MetadataDurationPlayer: clipping already gives the timeline the real duration, and the forwarder could publish a wrong metadata duration for direct play
- drop the dead PlaybackState.error/lastError now that errors are toast-only, and tighten the floor test to assert the exact value
Media3 treats a progressive stream as live, and ignores seeks, when neither the HTTP length nor the extractor duration is known. A transcoded response is chunked with no length and ffmpeg writes no MP3 duration header when streaming, so seeks stopped working once estimateContentLength was dropped. The server estimate is not a fix either: it under-counts (23% at mp3/24) and truncates the track.
Transcoded URLs now carry a declared upper-bound length in the fragment (never sent to the server). KnownLengthDataSource hands that length to Media3, keeping the stream seekable while never bounding reads below the real size. MetadataDurationPlayer reports the library duration to the session so the notification and UI show the true length rather than the upper bound.
Combine max bitrate and transcode format into one StreamQuality and store a separate value per network mode (Wi-Fi vs mobile data). NetworkMonitor reports metered vs unmetered via ConnectivityManager, SourceRepository selects and exposes the active quality, and PlaybackController reloads the window at the current position when it changes, so a network switch re-issues stream URLs with the new settings. Reset Coil's singleton in SubtracksApp.onCreate alongside Koin, since ArtworkSeedCache's background scope can call get() across Robolectric tests and poison the next Application.
Spell out the sync contract: browsing, filtering and sorting never touch the network,
only media bytes and images are on-demand, and a server-derived sort key has to land in a
local column at sync time rather than being requested lazily.
- resolve() no longer discards a stored seed when the bitmap cannot be decoded (it used to
return null, dropping the theme for pre-v12 rows); it falls back to the stored pair
- fold the busy flag into the seed cache value so eviction is atomic (a busy entry could be
evicted from the separate flag LRU while its seed stayed, silently disabling the scrim)
- the artist top bar samples heroBarColor at scroll 0 to match the static HeroGradient, and
drops the wrong scroll estimate and per-pixel recomposition
- rememberOverlaidNameBusy keys its state so the cached flag is read on key change, not only
the first composition; bottomBandBusy bails out on an empty bitmap
- SyncManager now uses a conflated request channel instead of tryLock, so a
request that arrives during a sync (e.g. add-source switching the active
server) is queued and runs afterwards against the then-active source
instead of being dropped.
- Paged loops count raw server rows, not accepted entities, so an empty-id
row on an otherwise full page no longer ends the scan early and prunes
the unseen tail.
- The cap now fails when the page just past it is non-empty, not only when
it is full, matching the bound the error message reports.
- fetchRank rethrows the cap instead of downgrading an over-cap album scan
to empty ranks.
- Docs: the mutex lives in SyncManager, and the prune still holds the
existing-id set.
A full page at the cap is not proof of truncation, so a library whose
size is an exact multiple of the page size failed for no reason. Each
paged loop now keeps going one page past the cap and only throws when
that page comes back non-empty; a library up to the cap syncs normally.
Add a boundary test for the exact-cap case.
Also note the accepted per-batch observer invalidation churn in the sync
code and the architecture doc.
- Paged loops now throw when they hit maxPages with a full last page, so a
truncated enumeration aborts the entity's collect and skips its prune
instead of deleting rows the sync never saw. The cap is injectable for
tests.
- Move sync serialization into SyncManager (tryLock coalesces duplicate
requests) and construct SyncService there; SourceRepository only exposes
the active MusicSource. Removes the repo <-> sync import cycle.
- Re-throw CancellationException instead of reporting a cancelled sync as
failed.
- Add buffer(1) to the outer albums/songs/playlistSongs flows so their
flowOn channel cannot hold 64 batches.
- Rank prefetch is best-effort (missing frequent/recent no longer aborts
the album sync).
- Skip playlist entries without an id, keeping positions contiguous.
- Chunk stale-disc deletes like the other prunes.
- Update the implementation plan line that still described the old
single-transaction sync.
