Unlike calling signal.signal(): - This function can be called from any thread (and will cause the handler to be run by the main thread when the signal is received). - Handlers are cumulative: When a given signal is received, all registered handlers will be executed (with the exception that only the last handler to register with is_final_handler=True will be called). Handlers should make no ordering assumptions, other than that the last handler to register with is_final_handler=True will be called after all the other handlers. Args: signal_num: The signal number with which to associate handler. handler: The handler. is_final_handler: Bool indicator whether handler should be called last among all the handlers for this signal_num. The last handler to register this way survives; other handlers registered with is_final_handler=True will not be called when the signal is received. Raises: RuntimeError: if attempt is made to register a signal_num not in GetCaughtSignals. zPAttempt to register handler (%s) for signal %d, which is not in GetCaughtSignalsN)GetCaughtSignals RuntimeError_final_signal_handlers_non_final_signal_handlersappend) signal_numhandleris_final_handlers %platform/gsutil/gslib/sig_handling.pyRegisterSignalHandlerr,sQ4')) 47>6KL MM)0:&z*11':c|U[;a[UH nU"X5 M U[;a[U"X5 gg)zGlobal signal handler.
