tracetools_trace.tools.signals.execute_and_handle_sigint(run_function: Callable[[], None], fini_function: Callable[[], None] | None = None) → None

Execute a task and handle SIGINT to always finalize cleanly.

The main task function is interrupted on SIGINT. The finalization function (if provided) is always executed, either after the main task function is done or after it is interrupted.

Parameters:

  • run_function – the task function, which may be interrupted

  • fini_function – the optional finalization/cleanup function
