- offline_cache::cache_album fetches an album's tracks and batches them; wired
to a new ("album","cache") media-action arm + a cloud-download CircleAction in
the AlbumPageView header action row.
- Favorites track rows now enable show-download, so the direct per-row offline
button shows there too (not just album rows / cached tracks).
Rounds out Slice 2: trigger surfaces (per-row button on album+favorites, context
menu everywhere, bulk multi-select, album header), live status (spinner/check/
alert) + seeding, and the unlock padlock. qbz-slint compiles clean.
cc
A cached track now shows its "ready" check when a view is built, persisting
across navigation within the session (was: only live downloads showed state).
- offline_cache.rs: a session-wide CACHED_IDS set (mirrors fav_cache), seeded
from index.db ready rows via load_cached_ids() on login/restore, kept in
sync as downloads complete (mark_cached true) and copies are removed (false).
is_cached(id) reads it.
- The 7 TrackItem builders seed cache-status from is_cached (favorites/search
clone/precompute the id to avoid moving it before the borrow).
- auth.rs calls load_cached_ids after the offline cache activates.
qbz-slint compiles clean.
cc
The queued/downloading state showed a static loader-circle. Split it into its
own `if` arm that continuously rotates via animation-tick (same technique as
LoadingSpinner), isolated so the per-frame tick only drives a row while it is
actually downloading. The idle/ready/failed glyph stays static. Communicates
that the backend is working.
cc
Adds the 6th MultiSelectBar action -> offline_cache::cache_tracks(selected),
mirroring Tauri's bulk caching. Clears the selection after queuing. (Also
retires the cache_tracks dead-code warning.)
cc
The CMAF download opened the SecretBox (OS keyring -> secret-service -> a
synchronous zbus D-Bus round-trip) directly on a tokio async worker, which
panicked ("Cannot start a runtime from within a runtime") and poisoned the
vault mutex — every later attempt then failed and fell back to the legacy
plain-FLAC path. Playback never hit this because load_cmaf_bundle already runs
inside spawn_blocking.
- downloader: wrap the vault open + key wrap in tokio::task::spawn_blocking
(off the async pool), mirroring the playback decrypt path.
- secret_vault: get_or_init recovers a poisoned mutex (into_inner) instead of
wedging the vault for the rest of the session.
Verified at runtime: CMAF bundle now persists (tracks-cmaf/<id>/) and plays
back decrypted; no panic, no legacy fallback.
cc
TrackRow now renders the offline state the controller maintains:
- The offline button is stateful: cloud-download (none, click -> cache) ->
loader-circle accent (queued/downloading) -> circle-check accent (ready,
click -> uncache) -> triangle-alert red (failed, click -> retry). Shown on
surfaces that enable it AND on any row with active cache state.
- The unlock PADLOCK (user-requested, back from Tauri): a pulsing lock glyph
overlays the play cell while the track's CMAF bundle decrypts, driven by the
`unlocking` flag the row_sink toggles on UnlockStart/UnlockEnd. New lucide
lock.svg / lock-open.svg assets.
The context menu's "Make available offline" already routes to caching. Testable
loop: cache a track (album button or context menu) -> watch it download -> play
it offline -> padlock pulses during decrypt. qbz-slint compiles clean.
cc
The Rust half of the trigger/status UI:
- offline_cache.rs: cache_track / cache_tracks / remove_cached + row_sink — a
CacheEventSink that reflects download status (queued/downloading%/ready/failed)
and the unlock padlock onto every visible row, plus terminal toasts. cache_*
pre-flight the limit, insert the queued row, and spawn the shared
spawn_track_cache_download with the core client.
- TrackItem gains cache-status / cache-progress / unlocking; set_row_cache_status
+ set_row_unlocking mirror set_row_favorite (walk the 6 track models + search
hero). All 7 exhaustive initializers updated.
- media-action arms ("track","cache"|"download"|"uncache") dispatch to the
controller; the play path now passes row_sink so UnlockStart/End fire the
padlock state during CMAF decrypt.
Compiles clean. Next: the TrackRow.slint affordance (make-offline button + ring
/ check / warn) and the padlock glyph that render these fields.
cc
- offline.rs: constructs + owns a per-user OfflineCacheState (same index.db +
library.db paths as Tauri, so the offline store is shared across frontends);
activated on login/restore, torn down on logout (hooks in auth.rs).
- playback.rs: play_audible + the gapless trigger now route through QbzCore's
play_track_resolved / fetch_for_gapless_resolved, so an offline-cached track
resolves from disk (decrypt -> play_data) before hitting the network. The
unlock-animation sink is None for now (padlock lands with the Slice 2 UI).
qbz-slint compiles clean. Offline PLAYBACK now works in Slint; the "Make
offline" trigger UI + per-row status + the padlock are next (Slice 2).
cc
The shared tier-walk compose methods both frontends call (player untouched):
- play_track_resolved: offline-first (resolve_offline_bytes -> play_data, warms
L1) else Player::play_track (which already does L1/L2 -> CMAF -> legacy).
- fetch_for_gapless_resolved: L1/L2 (player cache) -> offline -> network; the
offline tier is only tried when the track is NOT in the player cache (the
CMAF decrypt is slow, so a cached copy wins — matches the Tauri gapless order).
Both take the frontend's OfflineCacheState by ref (no duplicate DB handle) and
an optional CacheEventSink for the unlock animation. Compiles green.
cc
Adds qbz_core::offline_resolve::resolve_offline_bytes — the OFFLINE tier of
the playback tier-walk, frontend-agnostic and player-untouched (the user's
locked Slice-1 decision): resolve a track's offline-cached bytes by Qobuz id
(v2 CMAF decrypt via the secret vault, optionally emitting UnlockStart/End
through a sink; v1 plain-FLAC read; None on miss).
qbz-core now depends on qbz-offline-cache (aligns with the long-intended
`offline` feature seam). Both frontends will slot this in before the network
tier: Tauri keeps its hardware/quality gate around the returned bytes; Slint
calls it before Player::play_track. Player's L1/L2 + network path is unchanged.
Next: QbzCore compose methods (play_track_resolved / gapless), wire Slint's
session to construct + own an OfflineCacheState, route the Slint play path
through the resolver, and point Tauri's offline branch at it.
cc
Completes Slice 0. src-tauri now depends on the qbz-offline-cache crate; the
old src-tauri/src/offline_cache/ implementation files are deleted. What remains
in that module is a thin shim: a re-export of the crate plus the Tauri glue.
- offline_cache/mod.rs: pub use qbz_offline_cache::* + tauri_cache_sink (maps
CacheEvent -> the exact legacy offline:caching_*/offline:unlock_* app.emit
shapes, so the Svelte frontend is unchanged) + core_client (resolves the core
qbz_qobuz::QobuzClient from the CoreBridge for the download pipeline).
- Cache/redownload/migration commands: drop the legacy crate::api::QobuzClient
(state.client) + the CoreBridge double-plumb; pass one core client + an
app.emit-backed CacheEventSink. Unused `state: State<AppState>` params dropped.
- Playback + library cached-resolution call sites: pass &tauri_cache_sink(..)
to load_cmaf_bundle_with_ui_events instead of &app_handle.
- session_lifecycle: apply_persisted_limit now reads the persisted value here;
purge takes &library.db directly.
- migration: qobuz_client is the Option-wrapped core client (consistent with the
downloader); None mid-loop is recorded as a per-track failure.
Full src-tauri cargo check passes; behaviour-preserving for the Svelte frontend.
Backend extraction (ADR-006) done — next is Slice 1 (shared tier-walk in core).
cc
Completes the crate extraction (Slice 0 backend half):
- state: OfflineCacheState holder (db/fetcher/cache_dir/limit/semaphore/
library_db + dir-layout helpers + new/init_at/teardown). apply_persisted_limit
now takes Option<u64> (the caller reads it from offline_settings) instead of
borrowing src-tauri's OfflineState, so the struct is frontend-agnostic and
Slint can own one too.
- purge: purge_all_cached_files takes &Mutex<Option<LibraryDatabase>> directly
instead of src-tauri's LibraryState wrapper.
The crate is now self-contained (13 modules, no Tauri). Next: re-wire the
Tauri commands onto it with an app.emit-backed CacheEventSink and delete the
old src-tauri/src/offline_cache/ module.
cc
Moves the download pipeline into the crate and removes its Tauri coupling:
- event: new CacheEvent enum (Started/Progress/Completed/Processed/Failed/
UnlockStart/UnlockEnd) + CacheFormat + the CacheEventSink callback type.
- downloader: StreamFetcher + try_cmaf_offline_download + spawn_track_cache_download
now report through a &CacheEventSink instead of tauri AppHandle::emit. The
CoreBridge param is gone — both the CMAF raw download, metadata fetch, and the
legacy stream-url fallback unify on a single core qbz_qobuz::QobuzClient handle.
TLS uses the workspace rustls (same backend qbz-qobuz uses for all CDN traffic).
- playback: adds load_cmaf_bundle_with_ui_events that emits UnlockStart/UnlockEnd
through the sink (the pure load_cmaf_bundle is unchanged).
Crate compiles headless; 5 unit tests pass. Remaining for Slice 0:
OfflineCacheState + purge, then re-wire the Tauri commands with an
app.emit-backed sink and delete the old src-tauri module.
cc
Continues Slice 0. Moves the near-pure modules, re-pointing the src-tauri
client/library types to the core crates (the make-or-break for a mechanical
extraction — verified the field shapes match):
- metadata: fetch_complete_metadata now takes &qbz_qobuz::QobuzClient (was
crate::api::QobuzClient); body compiles unchanged against qbz_models.
- migration: crate::api::QobuzClient -> qbz_qobuz::QobuzClient,
crate::library::database::LibraryDatabase -> qbz_library::LibraryDatabase,
super::metadata -> crate::metadata.
- playback: the PURE load_cmaf_bundle fn (the UI-events wrapper stays out —
it becomes a CacheEventSink call in the next commit).
Deps added: qbz-models, qbz-library, tokio, reqwest, lofty. Crate compiles.
purge + OfflineCacheState + downloader (CacheEvent) remain.
cc
Slice 0 of the offline-cache port (extraction per ADR-006). Creates the new
qbz-offline-cache workspace crate and moves the tauri-free leaf modules out of
src-tauri/src/offline_cache/ verbatim:
- types: the shared serde DTOs (was inline in offline_cache/mod.rs)
- db: the SQLite cached_tracks index (super:: -> crate::types)
- secret_vault, cmaf_store, path_validator: moved verbatim
- maintenance: super:: refs re-pointed to crate::
src-tauri is untouched and keeps its own copy, so the production build stays
green; the re-point + delete happens at the end of Slice 0. Crate compiles
in isolation and all 5 unit tests pass.
Remaining for Slice 0: playback pure-fn split, metadata/migration/purge
(re-point crate::api/crate::library -> qbz_qobuz/qbz_library), the downloader
+ CacheEvent/CacheEventSink abstraction, the OfflineCacheState struct, then
re-wire the Tauri commands and delete the old module.
cc
The sidepanel left artist list is now always A-Z grouped (derive_artists
groups when group-enabled OR view-mode==sidepanel; the view toggle re-derives)
with letter headers, and an AlphaStrip on its right edge jumps the list
Flickable proportionally (same approach as the album grouping — not exact,
by design). Replaces the flat ListView.
cc
Add the grid<->sidepanel view toggle to the Artists toolbar (group select is
now grid-only, matching Tauri) and the sidepanel two-column layout: a
self-scrolling left list of SidepanelArtistRows (round thumb + name, selected
highlight) that calls select-artist, and a right column with the 5-state
machine (select-hint / loading / error / no-albums / sections). Each release
section renders its title + a flat AlbumCollectionView grid; a footer links to
the full artist page. The other-flick branch now excludes the sidepanel so the
two columns scroll independently.
cc
Wire the sidepanel backend ahead of its UI: select-artist loads the chosen
artist via artist::load_artist (reusing the /artist/page release_type
classifier per the user's decision) and apply_selected_artist maps its
release sections into selected-artist-sections (DiscoverSections) + total;
a FavoriteArtistAlbum artwork target fills the section covers. The
artists-set-view handler flips grid<->sidepanel (persisted as artists_view)
and clears the selection on the way back to grid. card_to_item is now
pub(crate) for reuse.
cc
Add the optional A-Z group toggle to the Artists grid (Group: Off/A-Z
QbzSelect, default Off, persisted via favorites_prefs artists_group).
derive_artists now buckets the filtered set into FavArtistSection letter
groups (# first, then A-Z) and builds the alpha-jump model; the grouped grid
renders per-letter headers + sub-grids and an AlphaStrip on the right that
jumps the Flickable proportionally (mirrors the Albums alpha grouping).
Also renames the favorites view header title "Favorites" -> "Library" to
match Qobuz.
cc
The per-view action+toolbar row is a HorizontalLayout whose sized children
are conditional per tab. When they are absent its auto vertical-stretch
becomes 1, so it split the leftover height with the scrolling content. The
Flickable-based tabs (artists/playlists/labels) have a small content
preferred height, leaving slack the row grabbed -> a giant empty sub-header.
Tracks/Albums looked fine only because their content fills. Pin the row to
vertical-stretch: 0 so the content always absorbs the slack.
cc
Add a Shuffle CircleAction to the Artists row-2 action cluster that opens a
random artist from the visible set (random ARTIST, not a random album —
matches Tauri). Adds favorites::random_visible_artist + the artists-shuffle
handler routing through invoke_open_artist.
cc
Point the artists grid at artists-visible (the search-filtered model) and
add the "No artists match your search" empty state. Add the Artists row-2
toolbar branch with the shared ExpandableSearch wired to artists-search +
search-artists -> derive_artists.
cc
Drop the albums_count line from the artist card (Tauri #169: Qobuz's count
includes compilations/tributes and is misleadingly high) — removed from
ArtistCard, map_artist, FavoriteArtistItem and FavArtistCard. Shrink the card
image to a 120px circle to match Tauri. Add derive_artists (name-substring
search filter → artists-visible/artists-shown), seeded on load; grouping +
the alpha strip layer on next.
cc
Add the FavoritesState fields for the Artists port: the grid toolbar
(artists-search / artists-view-mode grid|sidepanel / artists-group-enabled),
the search-filtered + A-Z-grouped models (artists-visible / artists-grouped
via the new FavArtistSection struct / artists-alpha / artists-shown), and
the sidepanel selection state (selected-artist-id/name, loading/error,
selected-artist-sections as DiscoverSections + total). Add the FavoritesActions
callbacks (search-artists, artists-set-view, artists-set-group, artists-shuffle,
select-artist). Controller + view follow.
cc
Add the user-requested grid/list switch to the Playlists toolbar
(parameterized the shared ViewToggle so albums + playlists both drive it)
and a new PlaylistListRow (collage thumb + name + owner·tracks + play +
overflow menu: play/play-next/queue/favorite), bound to playlists-view-mode.
The view mode persists via favorites_prefs (playlists_view). Tauri ships
grid only — the list view is a labeled Slint-better addition.
cc
Wire the playlist card media-actions: play / play-next / queue fetch the
playlist's tracks (core get_playlist) and route to playback play/enqueue;
share copies the Qobuz web-player playlist URL to the clipboard; favorite
toggles the LOCAL QBZ favorite (Library un-favorites in place and drops the
row, Following adds to Library — per user decision). Wire the sub-tab switch
and the name|owner search to derive_playlists. Add share::qobuz_playlist_url
and favorites::remove_playlist_row.
cc
Swap the passive single-cover FavPlaylistCard tile for the shared
discover/PlaylistCard (collage + hover overlay play/fav/more + context
menu) over playlists-visible, and add the Library/Following underline
sub-tab selector (no pills, ADR-008) above the grid with per-sub-tab and
search-empty states. Extend the shared PlaylistCard with a body-opens
prop so a favorites card-body click opens the playlist while the play
button plays (discover/search keep body=play, unchanged). Add the
Playlists search box to the row-2 toolbar. Remove the dead
FavoritePlaylistItem struct + playlists field + FavPlaylistCard.
cc
Replace the single merged get_user_playlists load with the two real
sources mirroring Tauri: Following = playlists the user follows but does
not own (get_user_playlists filtered owner.id != current_user_id);
Library = locally-favorited ids (SQLite get_favorite_playlist_ids) in
favorited order, intersected with the fetched set and falling back to a
single get_playlist for ids not present. Both map to the rich
SearchPlaylistItem (4-cover collage) via search::map_playlist/playlist_item,
replacing the single-cover PlaylistCard. derive_playlists picks the active
sub-tab source and applies the name|owner search filter; the 4-cover
artwork pipeline (FavPlaylistCover{following,index,slot}) fills the collage
and propagates into the search-filtered visible model. The tab badge now
counts the local Library set. Adds library_db::current_user_id.
cc
Add the FavoritesState fields for the Playlists port: two SearchPlaylistItem
sources (playlists-favorites = local Library, playlists-following = Qobuz
followed) + playlists-visible (current sub-tab after search), the transient
sub-tab/search/view-mode strings, and the following-count badge. Add the
FavoritesActions callbacks (playlists-set-sub-tab, search-playlists,
playlists-set-view, playlist-action). Wiring + controller follow.
cc
Add an ExpandableSearch to the Labels toolbar (mirrors tracks/albums),
wired to labels-search + the new derive_labels controller fn, which
forks a name-filtered clone of the loaded labels and shares the full
model when the query is empty (artwork stays live). apply_favorites now
derives the visible set on load.
cc
Replace the generic disc-icon row list (FavLabelRow) with FavLabelCard:
a 140px circular cover in an auto-fill grid, mirroring FavArtistCard and
the artists-grid layout. No-image labels show a disc-3 placeholder on an
indigo->violet gradient (1:1 with Tauri's label card). The grid renders
labels-visible and adds the "No labels match your search" state.
cc
The favorites-labels wire item (LegacyLabelDto) carries an `image`
field that FavLabel silently dropped, so label cards had no artwork.
Parse it (bare string or the object form, via label::extract_label_image),
plumb it onto LabelCard + FavoriteLabelItem, and issue a FavoriteLabel
artwork job + apply arm mirroring favorite artists. Align the count line
to "{n} albums" (matches Tauri and the sibling artist card) and seed
labels-visible for the upcoming search filter.
cc
In sm mode the open list options rendered at the standard body size while
the collapsed control shows 12px, so the dropdown looked oddly larger.
Use the same 12px for the option rows when sm (standard size unchanged).
cc
- QbzSelect sm now matches the favorites genre button: no outline, 6px
corners (was Radius.sm 8px), 12px label (was body). Standard size
(Settings) unchanged.
- ToggleButton snaps its icon to whole pixels (the HeaderBar/QueueSidebar
treatment) so the grid/list glyphs render crisp instead of blurry.
- AlbumCollectionView grouped sections now follow the view mode: in list
mode each group renders AlbumListRow rows (column header once on top)
instead of always a card grid, so group + list no longer conflict.
cc
The artwork pipeline wrote a decoded cover into the SOURCE model
(FavoritesState.albums / .tracks) by index, but the views render the
derived albums-visible / albums-grouped / tracks-visible models, which
are independent clones whenever a sort/group/search is active. So a
late-arriving cover never reached the rendered card (grey until a
re-derive). Add favorites::set_album_artwork / set_track_artwork to also
propagate the cover by id into the rendered model(s); apply_artwork calls
them for FavoriteAlbum / FavoriteTrack. The disk cache was already in use;
this was purely the render target.
cc
Add a Bootstrap-style `sm` flag to the shared toolbar primitives
(QbzSelect, ExpandableSearch, ToggleButton) — default stays the standard
size (Settings keeps it), and the favorites toolbar opts in (genre /
group / sort / search / grid-list now ~30px). FavGenreButton + the
favorites grid/list ViewToggle shrink to match. Also vertically center
the MultiSelectBar action buttons (only the count was centered before).
cc
Add an AlphaStrip overlaid on the right edge when grouping
alphabetically: tracks "Group: Name" (jumps the virtualized ListView to
the first row of a letter — accurate, uniform 50px rows) and albums
"Group: A-Z" (jumps the grid Flickable proportionally by section ordinal
— approximate, always lands the section in view, per the agreed
ArtistView-style behavior). derive_tracks/derive_albums build the
per-letter jump model (tracks-alpha / albums-alpha).
cc
Drop the redundant "N tracks" / "N albums" toolbar count (the tab-menu
badge is now the permanent counter) and split the content area: the
Tracks tab renders in a virtualized, self-scrolling ListView +
ListScrollbar (the PlaylistView pattern, now possible thanks to the
fixed-chrome restructure), while Albums/Artists/Playlists/Labels keep a
Flickable. Loading/error states center in the content area. Group headers
+ all per-row behavior are preserved inside the ListView items.
cc
Favorites tab badges previously showed a count only after visiting each
tab (the per-tab load set its own total). Add favorites::load_counts —
cheap limit=1 probes per type + the playlist count — applied to
FavoritesState once at startup, so all five badges in the new tab menu
are populated before the user opens a tab. A tab's own load still
refreshes its count.
cc
Rework all five favorites views into a fixed chrome block over a single
scrolling content area (prerequisite for list virtualization):
- Row 1: back/forward + "Favorites" title inline (left), the tab menu as
one floating group (right) — new FavTabMenu.
- Row 2: per-view action buttons (Play/Shuffle/select) float left, the
per-view toolbar (count + search + genre + group + sort + grid/list)
floats right. Lifted out of each tab's content into the fixed row.
- The lists/grids now scroll in a self-contained area below the divider
(own Flickable + ListScrollbar), instead of the whole page scrolling.
Behavior (search/sort/group/genre/multi-select/headers) unchanged.
cc
When grouping the favorites tracks by album or artist, render a header
row each time the group key changes (computed inline from the previous
visible row, no extra model field), and hide the redundant album column
in album-group mode (mirrors Tauri). Name grouping keeps its alphabetical
reorder. Completes the group-by UX without a structural list rewrite.
cc
Extend the favorites tracks bulk bar beyond Remove: Play next and Add to
queue build the queue from the already-loaded Track objects (new
playback::enqueue_tracks, no re-fetch; play-next inserts in order), and
Add to playlist opens the picker for the whole selection. The picker
gains track-ids for bulk add (open_multi); on_pick adds every id via the
existing add_tracks_to_playlist. Make-offline stays out (no Slint
offline-cache path yet).
cc
New favorites_prefs module stores albums view/sort/group + tracks group
in <data-dir>/qbz/favorites_ui.json (search stays transient). Loaded into
FavoritesState on each favorites navigation (before the data applies),
saved on every toolbar change; apply_favorites now re-derives on load so
the restored sort/group take effect (also fixes a latent case where a set
group mode wasn't applied after a tab reload). Album view toggle routes
through an albums-set-view action to persist it.
cc
Make genre_filter.rs selection per-context (HashMap keyed by "discover" /
"favorites" + a current context the popup edits), so favorites filters
independently from Discover. Discover keeps its server-side path
unchanged (reads filter_ids("discover") explicitly; its genre buttons set
the "discover" context on open). Favorites get a genre button in both
toolbars that opens the shared popup in the "favorites" context, plus the
popup overlay; derive_tracks / derive_albums filter client-side by the
selected genre NAMES (selected_names expands parents to descendants).
on_toggle / on_clear branch on the current context to re-derive favorites
instead of re-fetching Discover. AlbumSummary gains an optional `genre`
(favorites track album objects carry it; TrackItem can't, so a track
id->genre map backs the tracks filter). Persisted per-context (legacy
flat selection migrates to "discover").
cc
navigate_favorites stores the load error in FavoritesState.load-error
(cleared on each load attempt); the view shows a "Couldn't load
favorites" + detail + Retry block when set, and the tracks/albums tabs
are gated so the error replaces them instead of showing alongside an
empty state. Retry re-navigates the current tab.
cc
Add a group QbzSelect to the Tracks toolbar. derive_tracks reorders the
visible rows by the group key (album+title, artist+album+title, or
title) so a group's tracks sit together. Visible group-header rows are
deferred until the list is virtualized (the list is a plain for today);
this is the group-ordering half, matching how Tauri's tracks tab uses
grouping as the ordering mechanism.
cc
Add a group QbzSelect to the Albums toolbar. derive_albums buckets the
filtered set by artist name or by the title's first letter (# for
non-alphabetic), sections ordered alphabetically, rendered through the
shared AlbumCollectionView grouped path. albums-shown carries the
post-filter count so the count line + no-match state stay correct in
grouped mode.
