[issue44886] asyncio: create_datagram_endpoint() does not return a DatagramTransport
New submission from Thomas Trummer :
According to the documentation[1] loop.create_datagram_endpoint() returns an
asyncio.DatagramTransport. However on Windows this is not the case when the
ProactorEventLoop is used (which seems to be the default since Python 3.8).
This is a problem because a DatagramProtocol subclass needs a downcast in order
to satisfy the type system (or mypy for that matter).

# Will print: False
import asyncio
class EchoServerProtocol(asyncio.DatagramProtocol):
def connection_made(self, transport):
print(type(transport), isinstance(transport, asyncio.DatagramTransport))
async def main():
transport, protocol = await
asyncio.get_running_loop().create_datagram_endpoint(
lambda: EchoServerProtocol(),
local_addr=('127.0.0.1', ))
try:
await asyncio.sleep(5)
finally:
transport.close()
asyncio.run(main())

[issue44948] DeprecationWarning: Using ioctl() method
New submission from Thomas Trummer :
DeprecationWarning: Using ioctl() method on sockets returned from
get_extra_info('socket') will be prohibited in asyncio 3.9. Please report your
use case to bugs.python.org.
Use case:
def connection_made(self, transport: asyncio.BaseTransport) -> None:
sock = transport.get_extra_info('socket') # type: socket.socket
sock.ioctl(SIO_UDP_CONNRESET, False)
