Add the Bungee scaler implementation and wire it into Mixxx's keylock engine path without carrying vendored Bungee source.
Add regression coverage for Bungee keylock scaler selection and buffer-window accounting behavior.
Resolve Bungee through package, vcpkg, or module discovery and normalize every provider to the Bungee::Bungee target.
Add the pinned ExternalProject fallback and permanent Bungee/pffft patch homes so non-vcpkg builds do not depend on the temporary overlay.
Default Bungee on, seed preference defaults, and keep Dual-threaded Stereo UI state consistent with the selected keylock engine.
Document the cleanup point in the clean stack: this branch was built without tracking lib/bungee source, and dependency paths now resolve through package, vcpkg, module, or source-fetch providers.
Add Flatpak Eigen3, pffft, and Bungee modules before Mixxx and point Bungee patches at the permanent cmake/patches/bungee home.
Add the Bungee ASan workflow, dependency path filters, sanitizer source-fetch environment, and build workflow coverage.
Document Bungee build modes, dependency fallback prerequisites, Flatpak/CI notes, and the runtime invariants maintainers need for validation.

m_pendingKeylockEngineis written to the per-channelControlObjects and touserSettings()unconditionally, beforesetConfig()is called and its result checked.

Inline comments:
In @.github/workflows/bungee-asan.yml:
- Around line 33-51: The ASan workflow path filters are missing the KeyControl
wiring touched by this PR, so failures in that area won’t trigger the targeted
job. Update both the push and pull_request path lists in the bungee-asan
workflow to include src/engine/controls/keycontrol.* alongside the existing
engine, settings, and test paths. Use the KeyControl-related entries in the
workflow comments and the keycontrol.cpp changes as the reference points when
adjusting the filter set.
In `@src/engine/bufferscalers/enginebufferscalebungee.cpp`:
- Around line 336-354: Flush output frames are being truncated in
EngineBufferScaleBungee::copyFlushOutputFrames because it copies only the
current buffer space and drops any leftover from m_outputChunk. Update
copyFlushOutputFrames to persist unconsumed flush frames into
m_remainingOutputFrames and m_outputChunkConsumed, mirroring the leftover
handling in processGrain, so the next scaleBuffer call can continue flushing
instead of losing samples. If needed, adjust the constness of
copyFlushOutputFrames or make the tracked state mutable so the leftover
bookkeeping can be updated.
In `@src/engine/enginemixer.cpp`:
- Around line 36-46: Simplify the per-deck keylock default lookup by removing
the redundant outer pConfig->getValue(deckKey, ...) call and using
defaultKeylockEngineForDeck(pConfig, deckKey) directly where the deck setting is
read. The helper defaultKeylockEngineForDeck already resolves the deck key,
global key, and EngineBuffer::defaultKeylockEngine fallback, so the extra lookup
just re-evaluates deckKey and makes the fallback chain harder to follow. Update
the corresponding call sites in enginemixer.cpp (including the
Channel1/Channel2-4 usages) to keep the logic single-pass and clear.
In `@src/qml/qmlsoundmanagerproxy.cpp`:
- Around line 179-187: The QmlSoundManagerProxy keylock setting is being
mirrored into per-deck storage, which can overwrite existing deck-specific
overrides. Update the setKeylockEngine/getKeylockEngine flow in
QmlSoundManagerProxy so it only persists the shared default keylock_engine value
and does not commit the setting into Channel1 through Channel4. Keep the
deck-specific keys untouched when saving, and use the existing
EngineBuffer::defaultKeylockEngine and userSettings access pattern to locate the
shared setting.
In `@src/test/settingsmanager_test.cpp`:
- Around line 40-56: Extend explicit per-deck coverage in
explicitPerDeckKeylockEngines so the settings tests exercise Bungee and
SignalSmith values, not just SoundTouch/RubberBand. Update the helper in
settingsmanager_test.cpp to return a mix of EngineBuffer::KeylockEngine entries
that includes the new backends, and keep the existing preservation test using
that helper so it verifies explicit per-deck values survive round-tripping for
Bungee/SignalSmith as well.

Extend EngineBufferAlignmentTest with an opt-in CommonScalerPositionTrace scenario for every available keylock engine and both unity and stretched forward playback. Capture per-callback play positions, read-ahead ranges, effective rate, scaler visual offsets, visual-play predictions, marker data, and output finiteness in an atomically written TSV trace. Add the focused friend declaration needed by the test to inspect the selected scaler and keylock state. Keep the trace disabled unless MIXXX_ENGINE_POSITION_TRACE_DIR is set and document its forward-only, synthetic-timing limitations.
Make the alignment test warning-clean across the CI toolchains by guarding optional keylock marker thresholds, replacing the infinity initializer with a finite sentinel, and making size_t-to-int conversions explicit. Update the SoundTouch 2.4.0 Flatpak archive checksum to the hash of the current Codeberg download, matching the artifact observed in CI.
The bungee alignment change introduced a lower-bound clamp on visual play positions. That erased negative preroll positions used by EngineSync phase matching and caused BeatDistanceBeforeStart and BeatContextRounding failures across CI platforms. Retain the upper track-end cap when converting absolute play positions to fractional positions, while allowing signed preroll values through. Pass the signed visual play position from updateIndicators to the conversion helper. Validated in mixxx-build: - Rebuilt mixxx-test successfully. - All 61 EngineSyncTest.* tests passed. - Visual play-position, engine-buffer-alignment, and BeatsTranslate tests passed.
Integrate upstream/main at 6d9be24 while preserving the fork's Bungee and Signalsmith engine support, signed negative-preroll EngineSync behavior, opt-in engine position tracing, and CI portability fixes. Resolve the overlapping keylock-engine changes by adding upstream RubberBand R3 short-window support, retaining the fork-specific scalers and signal setup, and assigning unique persisted enum values to Bungee and Signalsmith. Adopt upstream workflow updates and the SoundTouch 2.4.1 checksum. Validation: CMake reconfiguration and the mixxx-test build started successfully in the mixxx-build distrobox. The build was intentionally interrupted by the user at approximately 36% before completion. No unresolved merge conflicts remain.
Restore the global [App],keylock_engine control while keeping per-deck keylock settings authoritative, and remove redundant per-deck configuration lookups. Update the QML sound manager proxy to save only the global selector and add migration coverage for Bungee and Signalsmith values. Preserve flushed Bungee frames across process boundaries and extend the flush-accounting regression test. Fix the benchmark workflow indentation, trigger Bungee ASan runs for keycontrol changes, and build Eigen3 out of source in Flatpak. Validated in mixxx-build: - cmake --build ... --target mixxx-test --parallel 1 (100% complete). - 81 focused tests passed; one opt-in trace test skipped. - EngineSyncTest.*: all 61 passed. - Exact prior CI failures SlowRubberBand, SoundTouchCrashTest, SoundTouchReverseTest, and RubberbandReverseTest: all passed.

Inline comments:
In @.github/workflows/bungee-asan.yml:
- Around line 21-22: Add a concurrency group to the “Bungee ASan” workflow so
newer runs for the same branch or pull request cancel superseded in-progress
runs. Keep the existing ASan job behavior and timeout unchanged.
- Around line 140-172: Move the explanatory VINYLCONTROL comments outside the
folded run scalar, placing them before the run field. Keep every CMake option,
including -DHID=OFF, -DINSTALL_USER_UDEV_RULES=OFF, VINYLCONTROL, and the ccache
launcher settings, inside the shell command so all flags are applied.
In `@cmake/patches/bungee/lower-cmake-minimum.patch`:
- Around line 20-21: Update the cmake_minimum_required declaration in the
lower-CMake patch to use version range 3.21...3.31, preserving the existing
policy ceiling while lowering the minimum supported CMake version.
In `@CMakeLists.txt`:
- Around line 5236-5239: Align the visibility settings in the QML block for
mixxx-qml-lib: update either the Bungee::Bungee link or the __BUNGEE__ compile
definition so both use the same PRIVATE or PUBLIC visibility, keeping the
definition’s propagation consistent with Bungee’s include directories.
- Around line 4872-4886: Change the BUNGEE option default from ON to OFF, while
leaving BUNGEE_FETCH_FALLBACK enabled and preserving explicit BUNGEE=ON settings
in build jobs that require it.
- Line 2898: Update the test-source configuration around
settingsmanager_test.cpp so the file is compiled regardless of BUNGEE. Preserve
conditional compilation only for Bungee-specific code or split the test sources
by dependency, ensuring the three unconditional tests and the __SIGNALSMITH__
test remain available when BUNGEE is OFF.
In `@docs/bungee-integration.md`:
- Line 33: Update the m_effectiveRate entry in the documentation table to state
that its m_dBaseRate × m_dTempoRatio value is latched at grain boundaries and
remains unchanged for queued output until the next boundary.
- Around line 91-94: Correct the documented muteHead formula to match the
implementation in engineBufferScaleBungee and the invariant that the buffered
input begins no later than the current input chunk: express it as availableBegin
minus inputChunk.begin, using the existing availableBegin definition. Leave
muteTail unchanged.
In `@packaging/flatpak/modules/bungee.yaml`:
- Around line 21-23: Update the post-install sed transformation for
unofficial-bungee-config.cmake to preserve the find_dependency(Eigen3 CONFIG)
and find_dependency(pffft CONFIG) lines, while retaining removal of only the
unwanted configuration checks or other unsupported directives. Ensure the
installed package config can define Eigen3::Eigen and pffft::pffft for the
exported unofficial::bungee::bungee target.
In `@res/qml/Settings/SoundHardware.qml`:
- Around line 63-68: Update the selector handling around keylockEngineId and
QmlSoundManagerProxy so one selection is applied to all four deck settings
rather than only the global keylock_engine value. Add or reuse dedicated proxy
APIs to persist the selected engine for Channel1 through Channel4, and invoke
each with the validated keylockEngineId while preserving the existing
loaded-engine check.
In `@src/engine/bufferscalers/enginebufferscalebungee.cpp`:
- Around line 183-217: Document the intentional partial-consume behavior in
consumeReadAheadGap when consecutive zero reads exhaust the retry budget, noting
that callers may receive fewer frames at end-of-track and the subsequent
processing path handles the resulting reset. Alternatively, add an
EngineBufferScaleBungeeBufferWindowTest case that verifies this incomplete-gap
behavior; keep the existing retry logic unchanged.
In `@src/engine/bufferscalers/enginebufferscalebungee.h`:
- Around line 3-14: Update EngineBufferScaleBungee and every other production
header that includes gtest/gtest_prod.h so mixxx-lib can resolve the GoogleTest
dependency, either by adding the required GoogleTest include dependency to
mixxx-lib or replacing FRIEND_TEST usage with explicit friend declarations.
Preserve the existing test-access behavior and apply the chosen approach
consistently across all affected headers.
In `@src/engine/enginebuffer.cpp`:
- Around line 812-819: Update EngineBuffer::fractionalPlayposFromAbsolute to
clamp absolutePlaypos to the valid track range on both sides before dividing,
ensuring negative positions produce a zero fraction while retaining the existing
upper-bound clamp.
- Around line 936-972: Remove the qWarning debug output from the
engine-selection switch in slotKeylockEngineChanged, including the SoundTouch,
RubberBand, and default branches. Do not add replacement logging; leave engine
selection behavior unchanged.
- Around line 317-337: Move the m_pKeylockEngine->connectValueChanged call for
slotKeylockEngineChanged until after all scaler objects are constructed,
including optional scalers, while preserving the explicit
slotKeylockEngineChanged call that applies the stored keylock value.
- Around line 941-958: Prevent concurrent reconfiguration of the active
RubberBand scaler in the KeylockEngine selection flow: update useEngineFiner()
and useOptionWindowShort() only on an inactive, fully initialized scaler, then
publish it after configuration, or serialize these calls with scaleBuffer()
processing. Ensure m_rubberBand cannot be cleared or rebuilt while audio
processing accesses it; the m_pScaleKeylock handoff alone is insufficient.
In `@src/engine/enginebuffer.h`:
- Around line 27-34: Replace the conditional Bungee and SignalSmith scaler
includes in EngineBuffer’s header with forward declarations for the pointer
member types used by EngineBuffer. Keep the concrete scaler headers included in
enginebuffer.cpp, and retain the RubberBand header because its inline API is
used by getKeylockEngineName().
- Around line 404-406: Remove the duplicate FRIEND_TEST declarations for
BungeeEngineSelected, BungeeKeylockToggleDoesNotCrash, and
BungeeKeylockEngineSwitch in EngineBuffer, keeping only one set of declarations.
In `@src/test/enginebufferalignmenttest.cpp`:
- Around line 66-69: Replace the hardcoded /tmp paths used by kTracePath and
kEngineMarkerTracePath with paths built through QDir’s portable
temporary-directory handling, matching writeCommonScalerPositionTrace(). Apply
the same change to both corresponding trace-path declarations so
writeFailureTrace() and writeEngineMarkerFailureTrace() can create diagnostics
on Windows.
- Around line 673-676: Handle the outputFrame == -1 sentinel from
findEngineMarkerOnset before computing result.callbackIndex, and ensure the
corresponding bestCallback calculations also avoid integer-division truncation
and retain the not-found state. Update the callback-index consumers to skip
probe/callback data when no onset was found while preserving normal indexing for
valid output frames.
In `@src/test/enginebufferbungeetest.cpp`:
- Around line 1-19: Guard the Bungee-specific test code so non-Bungee builds do
not compile it: in src/test/enginebufferbungeetest.cpp lines 1-19, wrap the file
content with the __BUNGEE__ conditional and add the required span include; in
src/test/enginebufferscalebungeetest.cpp lines 1-22, apply the same __BUNGEE__
guard around its Bungee-only declarations, or ensure CMake excludes both test
files when Bungee is disabled.

Move the explanation outside the folded run: scalar. YAML folds the # lines into the shell command, so the shell ignores every argument after the first #. This drops -DHID=OFF and all later flags, leaving HID and INSTALL_USER_UDEV_RULES enabled by default. VINYLCONTROL and ccache remain enabled by their Linux defaults.

…nerated by an AI Agent. Fix CI formatting, Flatpak packaging, and keylock setup Apply the complete formatter output required by the PR-range pre-commit run, including clang-format and gersemi changes across the affected C++ and CMake files. Fix nested-shell quoting in localuser.sh without suppressing ShellCheck, and correct the Bungee ASAN workflow command folding and concurrency handling. Keep Eigen builds out of source and install its license files from the correct source-tree-relative path. Route QML keylock selection through a deferred all-deck update that applies controls and persists Channel1 through Channel4 after audio devices close. Clarify that the real-DJ prerequisite applies to pull requests targeting main while retaining human review and deliberate publish requirements. Validation: mixxx-qml-lib, mixxx-test, and mixxx built successfully in mixxx-build; focused tests passed with one opt-in skip and three disabled tests; git diff --check and bash -n passed.

- Around line 920-923: Update the base-only ANLZ read flow around readAnalyze so
it passes true to include SECTION_TAGS_BEAT_GRID, then perform a separate
false-mode read when cue import is also required; preserve the existing
ignoreCues behavior in the SECTION_TAGS_BEAT_GRID handling.

For testing, has per-deck audio engine, and some patches for both Signalsmith as well as for Bungee - so needs cherry-picking from.
