[New-bugs-announce] [issue22429] asyncio: pending call to loop.stop() if a coroutine raises a BaseException

[STINNER Victor]

New submission from STINNER Victor:

Attached script stops immediatly whereas I would expect that the second call to run_forever() keeps running. If you execute the script, you will see:

deque([<Handle _raise_stop_error() at /home/haypo/prog/python/default/Lib/asyncio/base_events.py:94>])

The first call to run_forever() keeps a pending call to loop.stop() (to _rase_stop_error() in fact).

I don't know if it should be called a bug or if this surprising behaviour should be documented.

See also the issue #22428.
