TypeError: signal handler must be signal.SIG_IGN, signal.SIG_DFL, or a callable object #396
Closed
Description
If you register a signal handler for SIGTERM, start the event loop then kill it with CTRL + C, you get this error:
Exception ignored in: <bound method BaseEventLoop.__del__ of <_UnixSelectorEventLoop running=False closed=True debug=False>>Traceback (most recent call last): File "/usr/lib/python3.5/asyncio/base_events.py", line 431, in __del__ File "/usr/lib/python3.5/asyncio/unix_events.py", line 58, in close File "/usr/lib/python3.5/asyncio/unix_events.py", line 140, in remove_signal_handler File "/usr/lib/python3.5/signal.py", line 47, in signalTypeError: signal handler must be signal.SIG_IGN, signal.SIG_DFL, or a callable objectMinimal code to get the error:
