[issue29742] asyncio get_extra_info() throws exception

R. David Murray added the comment: Thanks for the report and PR, but your fix is not obviously correct. In general exceptions are the way in Python that errors are reported, and asking for extra_info on a closed stream is an error. The exception raised is not clear, so perhaps the asyncio fo

Nikolay Kim added the comment: get_extra_info() returns optional transport information, I think it is ok to return None for closed transport. https://github.com/python/cpython/blob/master/Lib/asyncio/transports.py#L18 I propose this feature initially, during early tulip development but now I th

Yury Selivanov added the comment: > Thanks for the report and PR, but your fix is not obviously correct. Not for this particular asyncio method though, see asyncio PEP [1]. But there's an actual bug in the PR, instead of returning `None` we should return `default`. [1] https://www.python.org
