- Replaced the miniaudio dependency with custom OS audio device abstractions and backends.
- Implemented platform-specific audio playback and capture for macOS (Audio Queue), Windows (WASAPI), and Linux (PulseAudio/ALSA).
- Added a fallback stub backend returning errors for unsupported platforms.
- Updated audio stream handling with reliable fill guard wakeups and streamlined rate validation.
Bazel's patch parser applies pure-insertion -U0 hunks one line early,
which dropped the lib.rs layout asserts inside 'mod ffi' on linux builds
(E0433). Regenerated the text hunks with -U1 context and moved the C
probe block after the miniaudio include so no hunk touches the crate's
newline-less final line, which the parser also rejects. Verified the
patched lib.rs type-checks for all four linux binding sets and the
darwin natives + maudio_layout_test pass under bazel.
The 17.2.4 bump moved maudio-sys 0.1.4 -> 0.1.5, which upstreamed the
per-target pregenerated bindings this patch used to add; the old build.rs
hunks no longer applied (CONTENT_DOES_NOT_MATCH_TARGET) and broke every
bazel natives fetch. The rebased patch keeps only what upstream lacks:
- x86_64-unknown-linux-musl pregenerated bindings
- C static asserts + omp_maudio_* ABI probes for maudio_layout_test
- lib.rs compile-time layout asserts pairing with the C side
Hunks are -U0 so bazel's patch parser never sees the no-trailing-newline
marker in miniaudio_version_check.c. Also refreshed MODULE.bazel.lock
for the 17.2.4 Cargo manifest hashes.
The 17.1.6 Bazel migration dropped maudio's generate-bindings feature, so
the darwin addon shipped maudio-sys's Linux-shaped pregenerated miniaudio
bindings. Those bindings omit the MA_SUPPORT_COREAUDIO backend-state union
members that the macOS build of miniaudio.c actually contains, producing a
Rust/C ABI mismatch: capture callbacks saw zero channels and yielded no PCM.
Re-enable generate-bindings for apple targets only. Patch maudio-sys's build
script to branch on Cargo's TARGET rather than the build-script host, so a
macOS-hosted Linux/Windows cross-build keeps target-family pregenerated
bindings instead of incorrectly running Darwin bindgen. Repin the Bazel graph
to apply the patch and gate bindgen behind the apple target selects.
Fixes#6846
zig 0.14's cache corrupts under concurrent `zig cc` (ziglang/zig#18763):
with ~60 cc-compiling cargo build scripts running in parallel, cache
manifests end up referencing evicted objects ("failed to open
.../scanner.o: FileNotFound") and kill the build. Patch the hermetic
wrapper via single_version_override so compile-only steps (-c/-E/-S) get
private throwaway caches under the system tmp dir — cold vs warm is
~25ms for compiles, measured — while links keep the shared cache for
compiler-rt/crt reuse (~6s cold, 25ms warm) under zig's per-artifact
locking.
