The single-query signal handler in cli.py raises KeyboardInterrupt on SIGTERM/SIGHUP. For interactive 'hermes chat -q' that unwinds the main thread cleanly. For kanban workers spawned by the dispatcher, the worker process is likely to have a non-daemon thread alive (terminal _wait_for_process, custom plugins, etc.). With KeyboardInterrupt only the main thread unwinds; the non-daemon thread keeps the process alive, the gateway has already restarted, and the dispatcher's _pid_alive check returns True forever — task stuck in 'running' indefinitely. When HERMES_KANBAN_TASK is set (dispatcher-spawned worker), flush logging + stdout/stderr, then os._exit(0) instead of raising KeyboardInterrupt. The kernel reclaims the PID immediately, and the existing zombie-state detection in _pid_alive flips the task to crashed on the next dispatcher tick. detect_crashed_workers then re-spawns it on the following tick — no manual recovery needed. A SIGALRM(2s) deadman is armed before the flush so a pathological blocking-I/O flush can't wedge the worker forever. In practice the reporter measured flush in <1ms; the alarm is a failsafe, never the common path. Interactive (non-kanban) chat -q is unchanged — the env-gated branch only fires for dispatcher-spawned workers. Live verification on this machine: - Without HERMES_KANBAN_TASK + non-daemon thread alive: process hangs alive 4+ seconds after SIGTERM. Dispatcher's _pid_alive returns True → task stuck. - With HERMES_KANBAN_TASK + same non-daemon thread: process exits in 0.10s via os._exit(0). Dispatcher reclaims on next tick. Tests: - tests/hermes_cli/test_signal_handler_kanban_worker.py (3 cases): end-to-end subprocess test with a non-daemon thread, HERMES_KANBAN_TASK env, SIGTERM, dispatcher-style _pid_alive check. Plus a source-level invariant test catching future refactors that drop the env-gated exit. - 452/452 kanban tests pass. Co-authored-by: andrewhosf <andrewho.sf@gmail.com> |
