fix(backends): darwin/metal support across purego Go backends (#10481)
* fix(parakeet-cpp): darwin/metal support (libparakeet.dylib + DYLD path) The parakeet-cpp backend had no macOS support and panicked at startup on Apple/Metal nodes when purego.Dlopen could not find "libparakeet.so". Fix it across the same four layers the sibling voxtral backend already handles correctly: - main.go: default the dlopen target to libparakeet.dylib on darwin (runtime.GOOS), libparakeet.so elsewhere; PARAKEET_LIBRARY still wins. - Makefile: also stage the built libparakeet.dylib next to the Go sources. - package.sh: accept either the Linux .so[.X.Y] or the macOS .dylib when bundling instead of hard-failing when no .so is present (the macOS case); note that on Darwin only system frameworks are linked. - run.sh: on Darwin set DYLD_LIBRARY_PATH and PARAKEET_LIBRARY to the packaged .dylib; keep LD_LIBRARY_PATH + .so on Linux. Mirrors backend/go/voxtral. Assisted-by: Claude:claude-opus-4-8 Signed-off-by: Ettore Di Giacinto <mudler@localai.io> * fix(backends): darwin/metal support across purego Go backends The parakeet-cpp fix in the previous commit was an instance of a bug shared by nearly every purego/dlopen Go backend: the dlopen target was hardcoded to a .so name and run.sh exported only LD_LIBRARY_PATH, so the backend panicked at startup on macOS/Apple-Metal nodes (dyld needs the .dylib name and DYLD_LIBRARY_PATH). voxtral was the only backend handling this correctly. Apply the same four-layer fix (mirroring backend/go/voxtral) to the remaining affected backends: whisper, sherpa-onnx, ced, stablediffusion-ggml, vibevoice-cpp, qwen3-tts-cpp, omnivoice-cpp, crispasr, acestep-cpp, locate-anything-cpp, depth-anything-cpp, rfdetr-cpp, sam3-cpp, localvqe Per backend: - main.go (sherpa-onnx: backend.go, two libraries): default the dlopen target to the .dylib on darwin (runtime.GOOS), .so elsewhere; the existing <BACKEND>_LIBRARY env override still wins. - run.sh: on Darwin set DYLD_LIBRARY_PATH and point <BACKEND>_LIBRARY at the packaged .dylib; keep LD_LIBRARY_PATH + the Linux CPU-variant (avx/avx2/avx512) selection unchanged in the else branch. - package.sh: also bundle the .dylib and stop hard-failing when no .so is present (the macOS case). - Makefile: also stage the built .dylib. Notes: - stablediffusion-ggml and acestep-cpp build their lib as a CMake MODULE, which emits .so (not .dylib) on macOS; run.sh prefers .dylib and falls back to .so so both layouts work. - sherpa-onnx was already partly darwin-aware (Makefile/package.sh); only run.sh and the two dlopen defaults needed fixing. Linux behavior is unchanged. Verified gofmt-clean and `CGO_ENABLED=0 go build` for every backend.

feat(whisper-cpp): implement streaming transcription (#9751)
* test(whisper): wire e2e streaming transcription target Adds test-extra-backend-whisper-transcription, mirroring the existing llama-cpp / sherpa-onnx / vibevoice-cpp targets. The generic AudioTranscriptionStream spec at tests/e2e-backends/backend_test.go:644 fails today because backend/go/whisper has no streaming impl - this target is the failing TDD gate that the next phase makes pass. Confirmed RED locally: 3 Passed (health, load, offline transcription), 1 Failed (streaming spec hits its 300s context deadline because the base implementation returns 'unimplemented' but doesn't close the result channel, leaving the gRPC stream open until the client times out). Assisted-by: Claude:claude-opus-4-7 Signed-off-by: Ettore Di Giacinto <mudler@localai.io> * feat(whisper-cpp): expose new_segment_callback to the Go side Adds set_new_segment_callback() and a C-side trampoline that whisper.cpp invokes once per new text segment during whisper_full(). The trampoline dispatches (idx_first, n_new, user_data) to a Go function pointer registered via purego.NewCallback - text and timings are pulled by Go through the existing get_segment_text/get_segment_t0/get_segment_t1 getters. Wires the hook only when streaming is actually requested, to avoid a per-segment function-pointer dispatch on the offline path. Assisted-by: Claude:claude-opus-4-7 Signed-off-by: Ettore Di Giacinto <mudler@localai.io> * feat(whisper-cpp): implement AudioTranscriptionStream Wires whisper.cpp's new_segment_callback through purego back to Go so the streaming transcription RPC produces real, time-correlated deltas while whisper_full() is still decoding. Each segment becomes one TranscriptStreamResponse{Delta}; whisper_full's return is the TranscriptStreamResponse{FinalResult} carrying the full segment list, language, and duration. Per-call state is tracked in a sync.Map keyed by an atomic counter; the Go callback registered via purego.NewCallback is a singleton, dispatched through user_data. SingleThread today means only one entry is ever live, but the map shape matches the sherpa-onnx TTS callback pattern. The streaming path's final.Text is the literal concat of every emitted delta (a strings.Builder accumulated by onNewSegment) so the e2e invariant `final.Text == concat(deltas)` holds exactly. The first delta has no leading space; subsequent deltas are space-prefixed. The offline AudioTranscription path is unchanged. Closes the gap with sherpa-onnx, vibevoice-cpp, llama-cpp, and tinygrad, which already implement AudioTranscriptionStream. Verified GREEN locally: make test-extra-backend-whisper-transcription passes 4/4 specs (3 Passed initially under RED, +1 streaming spec now). Assisted-by: Claude:claude-opus-4-7 Signed-off-by: Ettore Di Giacinto <mudler@localai.io> * test(whisper-cpp): assert progressive multi-segment streaming Drives AudioTranscriptionStream against a real long-audio fixture and asserts len(deltas) >= 2. The generic e2e spec at tests/e2e-backends/backend_test.go:644 only checks len(deltas) >= 1 which is satisfied by both real and faked streaming - this spec is the guardrail that a future "fake" impl can't sneak past. Skipped by default (env-gated, like the cancellation spec); set WHISPER_LIBRARY, WHISPER_MODEL_PATH, and WHISPER_AUDIO_PATH to a 30+ second clip to run. Verified locally with a 55s 5x-JFK concat against ggml-base.en.bin: 1 Passed in 7.3s, deltas >= 2, finalSegmentCount >= 2, concat(deltas) == final.Text. Assisted-by: Claude:claude-opus-4-7 Signed-off-by: Ettore Di Giacinto <mudler@localai.io> * ci(whisper-cpp): add transcription gRPC e2e job Mirrors tests-sherpa-onnx-grpc-transcription / tests-llama-cpp-grpc-transcription. Runs make test-extra-backend-whisper-transcription whenever the whisper backend or the run-all switch fires, so a pin-bump or refactor that breaks streaming transcription gets caught before merge. The whisper output on detect-changes is already emitted by scripts/changed-backends.js (it iterates allBackendPaths); this PR just exposes it as a workflow output and consumes it. Assisted-by: Claude:claude-opus-4-7 Signed-off-by: Ettore Di Giacinto <mudler@localai.io> * fix(whisper-cpp): silence errcheck on AudioTranscriptionStream defers golangci-lint runs with new-from-merge-base=origin/master, so the identical defer patterns in the existing offline AudioTranscription path are grandfathered while the new ones in AudioTranscriptionStream trip errcheck. Wrap both defers in `func() { _ = ... }()` to match what errcheck wants without altering behavior. The errors from os.RemoveAll and *os.File.Close are not actionable inside a defer here (we're already returning), matching the offline path's contract.

feat(whisper): honor client cancellation via ggml abort_callback (#9710)
* refactor(transcription): propagate request ctx through ModelTranscription* Replaces context.Background() with the HTTP request ctx so client disconnects start cancelling the gRPC call.

feat(whisper-cpp): Convert to Purego and add VAD (#6087)
* fix(ci): Avoid matching wrong backend with the same prefix Signed-off-by: Richard Palethorpe <io@richiejp.com> * chore(whisper): Use Purego and enable VAD This replaces the Whisper CGO bindings with our own Purego based module to make compilation easier. In addition this allows VAD models to be loaded by Whisper. There is not much benefit now except that the same backend can be used for VAD and transcription. Depending on upstream we may also be able to use GPU for VAD in the future, but presently it is disabled.
