This PR adjusts cleanup of tasks by the
asyncio
runner. This allows payloads/services to die/abort with an explicitraise KeyboardInterrupt
without triggering aTask exception was never retrieved
warning.An unhandled
KeyboardInterrupt
gracefully stops the event loop, similar to how it stops regular synchronous programs. However,asyncio
considers a task killed this way still as exceptionally terminated and will issue a warning if the exception has not been retrieved. The changes of this PR ensure that theasyncio
runner takes care of retrieving all such exceptions from it own tasks.
