whisper: Shut down cleanly on stop - #4801
Conversation
wyoming-faster-whisper has no SIGTERM handler, so s6's default SIGTERM kills the process and the container exits with code 143, which newer Supervisor versions flag as an unclean shutdown. It does catch KeyboardInterrupt and exit 0 on SIGINT, so tell s6 to stop the service with SIGINT via the down-signal file. Same fix as speech_to_phrase; mechanism verified there with the full s6 init (docker stop ~3s, container exit code 0). Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

With the default 30s healthcheck interval the app can sit in the "Starting" state for half a minute after it is already serving. Use --start-interval=5s so readiness is detected within seconds once the model is loaded and the Wyoming port opens. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

What this PR changes
down-signalfile so the whisper service is stopped with SIGINT instead of SIGTERM.--start-interval=5s, normal interval stays 30 s).Background
Clean shutdown: same situation as speech-to-phrase (companion PR #4800): wyoming-faster-whisper installs no SIGTERM handler, so on stop the process dies from the default signal action and the container exits with 143, which newer Supervisor versions flag:
Its
__main__wraps the asyncio entrypoint inexcept KeyboardInterrupt: pass, so SIGINT already produces a clean exit 0 — s6-rc'sdown-signalfile makes s6 deliver SIGINT on service stop. Mechanism verified end-to-end on speech-to-phrase with the real s6 init (docker stop~3 s, clean service stop, container exit code 0); whisper's signal-handling code path is identical.Faster startup detection: with the default 30 s healthcheck interval the app can sit in "Starting" for half a minute after the Wyoming port is already open;
--start-interval=5sdetects readiness within seconds (measured 8 s start→healthy on speech-to-phrase with the same change). Requires Docker Engine ≥ 25 (HAOS ships well past that) and hadolint ≥ v2.14 in CI — see #4802, which should merge first.Longer term, a SIGTERM handler in python-wyoming's
AsyncServerfixes all Wyoming apps at once — submitted as OHF-Voice/wyoming#55; thedown-signalmakes this app well-behaved now and becomes redundant-but-harmless once that ships.🤖 Generated with Claude Code
