Exception
is not broad enough and does not catchasyncio.CancelledError
orKeyboardInterrupt
.transitions
will exclusively catchBaseException
from now on.This has to major implications: First
on_exception
is not called when a task is cancelled. This will happen when an asynchronous event cancels currently running callbacks or a KeyboardInterrupt is called. Second, whenqueue=True
CancelledError
will not cause the queue to get cleared and render the machine unusable from thereon.
