v2_library_list_folder_children, v2_library_list_folder_tracks,
v2_library_list_folder_tracks_recursive accept and forward the
exclude-network-folders flag.
cc
list_folder_children, list_folder_tracks, list_folder_tracks_recursive
now apply the same network-folder exclusion that flat-mode search
honors, so the tree rail and recursive playback see the same source
of truth. Tests cover the on/off cases.
cc
handleBulkPlayNext, handleBulkPlayLater, handleBulkAddToPlaylist now
call resetMultiSelect() so treeSelectMode and treeSelectedTracksById
are cleared alongside the existing flat-mode reset. Without this, the
BulkActionBar lingered with count 0 after firing from tree mode. The
tree-mode BulkActionBar's onClearSelection closure now delegates to
the same helper for consistency. resetMultiSelect was already
correct (it leaves trackPathById intact, which is what we want).
Also: warn when toggleTreeTrackSelection's cache-miss fallback hits a
track path with no parent folder, instead of silently returning.
cc
Verify the recursive listing returns an empty Vec (not an error) when
the requested folder path has no descendants — frontend treats empty
as "nothing to play/queue" and skips the toast.
cc
Folder-row checkbox in tree mode selects every descendant track via
v2_library_list_folder_tracks_recursive, deselects them on a second
click, and shows the standard indeterminate state when only some
descendants are selected. Track-kind rows in the tree honour the
same flow so users can deselect individual tracks from a partially-
selected folder. Both checkboxes share the existing selectedTrackIds
set, so the bulk-action bar (play next, play later, add to playlist)
operates on the union without any special-case handling.
Indeterminate state is computed cheaply: a SvelteMap<number, string>
caches track-id -> file_path (populated from the in-memory tracks
list and from each recursive fetch on toggle), and `countSelectedUnder`
walks the small selectedTrackIds set checking the prefix. Folder-row
state derives via a parent-supplied callback; the child reads the
prop reference of selectedTrackIds so reactivity propagates when the
parent reassigns the set.
Adds a dedicated treeSelectMode flag so the flat-mode tracks-tab
selection toggle stays independent. Renders the BulkActionBar at the
end of the tree-mode container when treeSelectMode is on. Adds a new
toast.failedSelectFolderTracks key across all five locales.
cc
Tauri wrapper for the qbz-library primitive added in the previous
commit. V2 cleanroom: direct call into qbz-library, no legacy
delegation. Registered in lib.rs alongside the existing folder-tree
commands.
cc
Returns full LocalTrack rows for every descendant under a folder path,
filtered by COALESCE(source, 'user') = 'user' so qobuz_download rows
never leak. Ordering is file_path ASC for stable on-disk reading
order across heterogeneous subtrees. Reuses escape_like_pattern so
literal '_' / '%' in path segments don't behave as LIKE wildcards.
Used by the tree-mode multi-select to populate selectedTrackIds when
the user ticks a folder-row checkbox; returns the full record (not
just IDs) so the frontend can build queue items without a second
round-trip.
Adds three unit tests covering the recursive walk, file_path
ordering, and special-character escape handling.
cc
When the user types in the search input while in tree mode, matching
folders/tracks stay visible and every ancestor path expands to keep
context. Empty branches collapse out. Clearing the query restores the
user's pre-search expand state. Implementation: in-memory contains over
the loaded `albums` array, debounced 200ms. The match expands the union
of matched paths and their ancestors in `searchExpandedPaths`, which
replaces `treeExpandedPaths` while search is active. Pre-search snapshot
is restored on clear. Tracks remain rendered under any visible folder.
cc
- Surface a toast on playback failure so the user gets UI feedback
rather than only a console error.
- Honor shouldExcludeNetworkFolders() for consistency with loadTracks
and the rest of the view's search invocations.

Wires LocalLibraryFolderTree (left rail, 240px fixed) and the
LocalLibraryFolderDetail / album-detail flow (right pane) into a
two-column shell that mirrors the Artists tab CSS byte-for-byte.
View-mode segmented control on the Folders toolbar toggles between
Flat (the existing folder-grouped list) and Tree (the new hierarchical
view). The toggle is hidden when browsing Hidden Albums so that
sub-view keeps its existing flat rendering.
Selection routes the right pane: folder paths matching a known
album_group_key drive the existing handleAlbumClick flow (which sets
selectedAlbum and renders the top-level album-detail view); non-album
folders open LocalLibraryFolderDetail with subfolder cards plus
direct-children tracks. Empty-state when nothing is selected uses the
library.foldersTree.selectAFolder string.
Recursive play: handlePlayRecursive fetches all tracks via
v2_library_search (limit:0), client-side prefix-filters on file_path,
sorts by path and queues the result. Backend does not yet expose a
recursive-tracks-under-path command — flagged as a Task 7 trade-off
to revisit if telemetry shows tree-mode play stalling on large
libraries.
Mode persists in library_preferences.folders_view_mode via the
existing v2_set_library_folders_view_mode command, hydrated on mount
through v2_get_library_preferences. Flat mode rendering is
byte-for-byte unchanged: zero deletions in the existing markup, the
new tree shell wraps it via an outer if/else.
LibraryPreferences type extended with the optional folders_view_mode
field so TS strict-mode passes on the new prefs.folders_view_mode
read.
cc
The folderPath snapshot existed but wasn't used to guard the async
writes. Rapid folder switches could land an older fetch's results on
top of the newer selection. Add three short stale-guards on .then,
.catch, and .finally so only the latest in-flight result wins.
cc
Renders the contents of a folder that is NOT a known album_group_key —
shows immediate subfolders + direct-children tracks side by side, with
a "Play all recursively" button for the whole folder. Used in the right
column of the upcoming tree-mode two-column layout (Task 7). Extracts
FolderTreeEntry to a shared $lib/types/folderTree.ts module so both
LocalLibraryFolderTree and FolderDetail import the same type.
cc
- Keep self-import for recursion and replace the misleading "deprecated
in Svelte 5" comment with a corrected rationale. svelte-check confirms
`<svelte:self>` is in fact deprecated in Svelte 5 (svelte_self_deprecated)
and self-import is the recommended replacement; the original code was
right, only the comment was wrong.
- Switch the row role from `button` to `treeitem` so that `aria-selected`
is valid (svelte-check rejects aria-selected on role=button) and add
`aria-expanded` for folders. treeitem is also the semantically correct
role for a tree row, so screen readers now announce both selection and
expansion state.
- Add :focus-within parity for the play button so keyboard users see it
when the row receives focus.
cc
Lazy-loaded recursive tree-row component for the upcoming tree mode in
the Folders tab. Renders one node per call; children loaded on first
expand via v2_library_list_folder_children. ADR-001 compliant (no $t
inside $derived). Indentation by depth * 16px matches Poweramp-style
hierarchy. Recursion uses self-import pattern (svelte:self deprecated
in Svelte 5). Not yet wired into LocalLibraryView - that lands with
the two-column layout integration (Task 7).
cc
Task 4's structural change of `library.folders` from string to object
broke LocalLibraryView.svelte:4337's dynamic tab label
($t(`library.${tab}`)) which expects a string. Move the new tree keys
to a sibling namespace `library.foldersTree.*` instead, and restore
`library.folders` to its original flat string value.
cc
Five locales (en, es, de, fr, pt). en and es are human-written in the
project's canonical Mexican neutral register; de/fr/pt are machine-
translated drafts flagged in qbz-nix-docs/i18n/pending-translations.md
for community review. Seven keys: modeLabel, flatLabel, selectAFolder,
treeFolderTracks (ICU plural), treeLoading, treeEmpty, playAllRecursive.
The flat library.folders string ("Folders" / "Carpetas" / etc.) was
migrated to an object; the original label is preserved at
library.folders.label. No source code currently references the key,
so the restructuring is non-breaking. "Track" is translated to match
each locale's existing convention (pista, Titel, titre, faixa).
cc
New persisted field on LibraryPreferences gating the upcoming Tree
sub-mode in the LocalLibrary Folders tab. Default flat preserves
existing behaviour for current installs. Migration adds the column
non-destructively. Setter v2_set_library_folders_view_mode exposes
the toggle to the frontend; the existing v2_get_library_preferences
returns the new field automatically via serde.
cc
- Replace the false "SQLite ORDER BY fragility" rationale on the
Rust-side sort in list_folder_children with the actual reason
(rows already in memory; Rust case-insensitive compare clearer
than COLLATE NOCASE on a CASE-derived column).
- Drop the redundant ESCAPE '\\' clause on the literal '%/%' pattern
in list_folder_tracks. The pattern contains no escape character;
the clause was a copy-paste artifact from the user-input LIKE
patterns where ESCAPE is required.
No behaviour change.
cc
Two new SQL primitives that walk local_tracks.file_path to reconstruct
filesystem hierarchy without schema changes. Both filter
COALESCE(source, 'user') = 'user' so Plex and Qobuz downloads are
excluded from the eventual tree-mode view in the Folders tab. Both hit
idx_tracks_file_path for the LIKE prefix% portion; per-row level
extraction is in-memory over the prefix-narrowed candidate set. New
FolderTreeEntry enum carries the child rows. Unit tests cover folder/
track interleaving, source filter, special-character paths, and
direct-children vs recursive scoping.

Issue #375: pause-then-resume sometimes leaves audio silent. Diagnosis
in user-reported logs:
Synced audio settings to CoreBridge player: backend=None, exclusive=false
...
Resume: reinitializing stream at 44100Hz/2ch
Using default audio device <- legacy CPAL path
Using audio device: Default Audio Device
Audio output initialized successfully <- silent stream
backend_type=None falls through to init_device's legacy CPAL path which
races against rodio's DeviceSink drop on resume — CPAL hands us a new
default-device handle, but PipeWire is still tearing down the previous
sink, and the new handle ends up routed to a node that produces no
sound. CPAL doesn't fail the open, just gives a silent stream.
The "Sync audio settings on startup" toggle Rico29 was asked to enable
fires correctly (`sync_audio_on_startup=true` in his log) but only
re-syncs whatever is persisted. His persisted backend_type was still
NULL because he never explicitly picked a backend, so the sync was a
no-op.
Fix:
- Default::default() now sets backend_type to Some(AudioBackendType::default()),
which picks PipeWire on Linux and SystemDefault elsewhere. New installs
go directly onto the proper backend init path; the runtime still
degrades gracefully if the chosen backend isn't available on the host
(try_init_stream_with_backend returns Some(Err(_)) and the existing
fallback warning fires).
- Migration backfills existing rows where backend_type IS NULL with the
same per-OS default, serialized via serde_json so the row read path
round-trips cleanly. macOS users were already getting effective
SystemDefault dynamically at the call site (audio_settings.backend_type
.or_else(...)) so behaviour there is unchanged; the migration just
persists what the runtime was already substituting.
reset_all picks up the new default automatically because it reads
AudioSettings::default().backend_type.
cc
Three issues observed when fast-scrolling collection detail views
(reported on the Macross collection, ~67 items, list mode):
1. Horizontal scroll artifact at the bottom-right corner — same root
cause as AlbumDetailView's: an absolutely-positioned artwork backdrop
widens past 100% of the .detail-view. Add overflow-x: hidden alongside
the existing overflow-y: auto.
2. Empty container when scroll position briefly exceeds the content
tail. The virtualWindow math could compute firstRow * cols >= total
during overscroll moments, slicing windowedItems to an empty array.
Clamp firstRow / firstIdx to total - 1 so at least one row renders
even when the scroll position has overshot.
3. The user-visible regression that started this thread: scrolling
UP from deep in the list could not reach scrollTop = 0 even though
the "Top" button worked. Two fixes layered together:
a. overflow-anchor: none on .detail-view. Browser scroll-anchoring
tries to preserve visual stability when content above the viewport
changes height — but the virtualizer manages its own spacer
heights, so the auto-anchoring nudges scrollTop in the opposite
direction of user input. Disabling it lets the wheel input win.
b. content-visibility: auto gated to expanded mode. Until now
.item-block applied it unconditionally. The grid view's .grid-card
already had this exact issue diagnosed and fixed (see the inline
comment "doubling up with content-visibility: auto caused cards to
re-eject and re-paint on scroll-back"); .item-block had been left
behind. Layering native content-visibility on top of manual
virtualization caused the browser to intermittently treat rendered
rows as off-screen during fast scroll, snapping them to the
contain-intrinsic-size hint for a frame, which the spacer math
doesn't predict — producing the empty-viewport-with-stuck-scroll
symptom. The .lazy class now scopes content-visibility to expanded
mode, where virtualization is OFF and the optimization is needed.
Smoothness during very fast wheel scroll is still imperfect but the
viewport no longer goes blank and scroll-up reaches the top reliably.
cc
The .has-art-bg ::before pseudo-element renders the album artwork
heavily blurred at transform: scale(1.15) for the Qobuz/Feishin-style
header. Without overflow-x: hidden on the .album-detail container, the
15% horizontal upscale of the absolutely-positioned backdrop bleeds
past the right edge and surfaces a horizontal scrollbar on the page.
Add overflow-x: hidden to the existing overflow-y: auto so the blur
stays clipped without affecting vertical scroll.
cc
Adds CoreAudio Hog Mode integration on macOS so Exclusive Mode actually
takes the device exclusively (previously the macOS path used the
Linux-shaped logic without any kernel-level lock). Pins the CoreAudio
device id through Hog Mode acquisition, sample-rate switching, and
stream creation so System Default doesn't drift mid-session. Linux
behaviour is unchanged.
Review asks (all four resolved by Vudgekek + afonsojramos):
- set_coreaudio_hardware_volume falls back to software volume on Err
rather than reporting success, so knob-only DACs keep a working
volume slider via engine.set_volume().
- CoreAudioExclusiveGuard snapshots the device's hardware volume on
acquire and restores it before releasing Hog Mode, so leaving
Exclusive Mode returns the DAC to the user's pre-Exclusive level.
Guard is constructed before the FFI call so partial-acquire failures
still trigger Drop and release.
- Linux unused-variable warnings on stream_opt and exclusive_guard
cleaned up via cfg_attr(allow(unused_variables)) on the macOS-only
guard plumbing. cargo check is clean.
- Silent shared-mode regression on macOS when backend init fails:
init_device now sets_current_device(None) and returns None on
exclusive_mode==true so the user sees an error instead of
unknowingly playing in shared mode.
Bonus: 5f10b4ba adds real CoreAudio device-rate detection for macOS
Shared Mode, +90 lines in backend.rs.
Conflict resolution: single textual collision in
crates/qbz-audio/src/lib.rs (both branches added a pub use line).
Resolved by keeping both, alphabetical order — coreaudio_direct
re-export from pr-391, device_reservation re-export from pre-release.
All other auto-merges verified line-by-line: AlsaDirectStream's
DeviceReservation::acquire flow (alsa_direct.rs:60-97), the macOS
exclusive_mode guard (player/mod.rs:1077-1085 in qbz-player and the
mirror in src-tauri:1024), and CoreAudioExclusiveGuard's volume
snapshot/restore (coreaudio_direct.rs:351,369,373,388) all coexist
correctly because each branch touched different functions.
cargo check clean across all four crates. 9 device_reservation +
3 reserve_dac + 214 src-tauri unit tests pass.
cc
Mirrors the HiFi Wizard control (landing in Task 8) inline under
Exclusive Mode. Status row polls v2_get_dac_reservation_status every
5s while the row is rendered. Hidden when the selected device is not
a card-specific ALSA prefix (hw:, plughw:, front:, surround*, iec958:,
hdmi:). Six i18n keys consumed at settings.audio.reserveDac.*.
cc
Five locales (en, es, de, fr, pt). English and Spanish are human-written
in the project's canonical Mexican neutral register; de/fr/pt are
machine-translated drafts. Pending-translations note recorded in
qbz-nix-docs/i18n/pending-translations.md (outside git scope).
Keys: settings.audio.reserveDac.{label, description, statusActive, statusContested, statusUnavailable, wirePlumberNote}.
UI surfaces (Settings mirror + HiFi Wizard) consume these in Tasks 7-8.
cc
- Document the Contested-vs-Unavailable classification limitation on
the DacReservationStatus enum and its call site, deferring the
stash-the-last-error refactor until Tasks 7-8 confirm the UI needs
the distinction.
- Lift is_card_specific_device to pub(crate) in lib.rs and delete the
duplicate in commands_v2/audio.rs to prevent the allow-list from
diverging when new ALSA prefixes are added.
- Drop the misleading "or non-card device" clause from the
apply_dac_reservation degraded-path log; non-card devices are
filtered earlier and cannot reach this log line.
No behaviour change.
cc
Lifetime B from the design spec: a long-lived DeviceReservation guard
held in AppState, gated by the reserve_dac_while_running setting.
Acquired at startup if the persisted flag is true and the selected
device targets a single ALSA card; reapplied when the user picks a
different DAC; released on toggle-off, on a switch to a non-card
device, or AppState drop.
DB persistence: ALTER TABLE migration adds the column, SELECT and
reset_all are extended, set_reserve_dac_while_running setter parallels
the established pattern for boolean audio settings.
Tauri commands (V2 cleanroom):
- v2_set_reserve_dac_while_running(enabled) - persist + apply
- v2_get_dac_reservation_status() -> DacReservationStatus
Status enum mirrors the four cases in the spec: Inactive (toggle off,
or non-card-specific device), Active (we hold the bus name), Contested
(another app holds the device at higher priority - guard is None but
the toggle is on), Unavailable (D-Bus unreachable, degraded guard).
v2_set_audio_output_device gains an AppState dependency so DAC changes
trigger a reservation handover when the toggle is on.
UI surfaces (Settings mirror + HiFi Wizard) land in Tasks 7-8.
cc
Opt-in flag for the per-process DAC reservation lifetime (Lifetime B
in the spec). Defaults to false; serde default ensures legacy settings
JSON files round-trip cleanly without the field. Task 5 will read this
flag in AppState startup and the v2_set_reserve_dac_while_running
Tauri command.
Strictly additive: no existing field changed, no behaviour change for
users with the flag at its default (false).
cc
The CARD= parameter in ALSA device strings refers to the card's short
id (e.g. "C20", "HDMI", "Generic"), not its long descriptive name
("Cambridge Audio USB Audio 2.0"). The previous resolver called
Card::get_name() and silently swallowed errors, so every CARD=<id>
lookup failed and acquire() degraded gracefully -- meaning the
reservation has been non-functional for users with named-card device
strings since Task 3 landed.
Reported by the maintainer on Cambridge DacMagic Plus exposed as
front:CARD=C20,DEV=0, 2026-05-07. Smoke-test scenario 2 had been a
false positive: audio worked because we degraded silently, not because
the reservation succeeded.
In alsa-rs 0.10, Card::get_name() wraps snd_card_get_name and despite
the name returns the LONG descriptive string. The short id (what
aplay -l shows in brackets and what CARD= references) is exposed via
ctl::CardInfo::get_id() (snd_ctl_card_info_get_id). Open a Ctl per
card, read the id from its CardInfo, and surface ALSA enumeration
errors as ReservationError::AlsaError instead of unwrap_or_default()
into an empty string.
cc
The previous parse_card_index only accepted hw: and plughw: prefixes,
which broke playback for users whose ALSA device string uses front:,
plughw:, surround*:, iec958:, hdmi:, etc. The plugin prefix is
irrelevant for D-Bus reservation purposes - what matters is the card
identifier in the args. Generalise the parser to extract the card
from any plugin prefix.
Defence in depth: when parse_card_index fails (unrecognised string,
no card identifier extractable, etc.), acquire() now logs a warning
and returns a degraded guard instead of propagating the error.
This preserves playback for non-card-targeting names like 'default'
and 'pulse' that are not meaningful for per-card reservation.
Reported on Cambridge DacMagic Plus exposed as front:CARD=C20,DEV=0,
2026-05-07.
cc
- Skip the 50 ms PipeWire-vacate margin on the degraded D-Bus path;
no reservation transition happened, so no settle delay is needed.
- Add TODO(Task 5) breadcrumb for the app_device_name placeholder
so Task 5's UI surfacing wires it to the user-facing DAC name.
- Soften the timing-claim comment on the sleep; the specific "~2-4 ms"
was spec-cited, not measured in this commit.
- Lift the 50 ms literal into a named PIPEWIRE_VACATE_MARGIN const.
No behaviour change for the active-reservation path.
cc
Acquire org.freedesktop.ReserveDevice1.Audio<N> before opening the PCM,
hold for the entire stream lifetime, release on Drop after the PCM
closes. Closes the path where exclusive open would silently fight an
active PipeWire route.
Field order in AlsaDirectStream is significant: _reservation is the
last field so it drops AFTER the PCM closes, ensuring the kernel-level
exclusive lock is released before the D-Bus bus name is freed and
PipeWire reclaims the device.
This is the canonical Lifetime-A consumer the device_reservation
acquire doc-comment's tight-coupling rule allows: a DeviceReservation
created immediately before a real PCM::new() and held for as long as
the PCM is open. A 50 ms defensive sleep gives PipeWire time to vacate
the device after releasing the reservation.
cc
- Document the load-bearing tight-coupling rule on acquire(): never
construct a DeviceReservation without an immediate device consumer.
Cambridge DacMagic Plus was stranded by a standalone reservation
churn during initial Task 2 smoke testing on 2026-05-07.
- Document the Connection lifecycle: zbus does not pool session-bus
connections, so acquire() pays a SASL handshake per call. Task 5
will add acquire_with_connection() to reuse a long-lived bus.
- Refactor resolve_contention to open a single holder Proxy and read
Priority + ApplicationName through it, instead of opening two.
- Specificity polish on the QBZ_APPLICATION_NAME dead-code comment;
defensive-InQueue comment; release_name From-chain comment;
clippy doc-list-overindentation fixes.
No behaviour change.

Implements the full priority-resolution algorithm: request bus name
with DO_NOT_QUEUE; on EXISTS look up holder Priority via the
Properties interface; if our priority (5) is higher, call
RequestRelease and retry with REPLACE_EXISTING; if equal-or-lower,
return HigherPriorityHolder. AlreadyOwner is treated as success for
same-connection idempotency. Drop releases the bus name and logs
the ReleaseName reply variant.
D-Bus failure paths degrade to a no-op guard so playback continues
exactly as before in environments without a session bus.
Smoke-tested against PipeWire/WirePlumber via dbus-monitor.
cc
- Add ReservationError::AlsaError variant; stop conflating ALSA
enumeration errors with DbusError.
- Mirror ReservationError variant set on the non-Linux stub so cross-
platform pattern matching compiles on every target.
- Add empty Drop to stub for RAII symmetry with the Linux variant.
- Collapse ReservationState to its real Task 1 shape (Degraded only);
Task 2 reintroduces Active when it has real fields.
- Rewrite acquire() doc-comment to honestly describe Task 1's behaviour
and hint at Task 2's full failure-mode set.
No behaviour change. Foundation commit for Task 2.
cc
Adds the new module that will host the org.freedesktop.ReserveDevice1
D-Bus client. This commit only ships the public surface, the parser
helpers (hw:N -> Audio<N> bus name, hw:CARD=name resolution) and unit
tests for them. acquire() currently returns a degraded guard; D-Bus
implementation lands in the next commit.

Address review feedback from the macOS Exclusive Mode PR.
Pin the resolved CoreAudio output device before acquiring Hog Mode so
System Default cannot drift between Hog Mode acquisition, sample-rate
switching, and stream creation.
Fall back to software volume when CoreAudio hardware volume is unavailable,
which keeps the volume slider usable on knob-only DACs.
Snapshot and restore CoreAudio hardware volume around Exclusive Mode so
leaving Exclusive Mode does not leave the output device at QBZ's last
hardware volume.
Refuse shared-mode fallback when macOS Exclusive Mode stream creation
fails, so the app does not silently play in non-exclusive mode while the UI
still reports Exclusive Mode.
Clean up Linux unused-variable warnings from the macOS-only guard plumbing.
Discord Rich Presence (#336): when the user opts in, QBZ pushes the current
