Description

@difeid
  • uvloop version: 0.17.0 - 0.20.0
  • Python version: 3.11.4 - 3.12.5
  • Platform: Linux
  • Can you reproduce the bug with PYTHONASYNCIODEBUG in env?: Not a bug
  • Does uvloop behave differently from vanilla asyncio? How?: Yes, not implemented feature

The uvloop not implement method sock_sendto.

coroutine loop.sock_sendto(sock, data, address)
Send a datagram from sock to address. Asynchronous version of socket.sendto()

Return the number of bytes sent.
sock must be a non-blocking socket.
New in version 3.11.

The simple test case that reproduces the problem:

#!/usr/bin/env python3

import socket
import asyncio
import uvloop

uvloop.install()

async def run():
    addr = ("127.0.0.1", 1111)
    s = socket.socket(socket.AF_INET, socket.SOCK_DGRAM)
    s.setblocking(False)
    loop = asyncio.get_running_loop()
    await loop.sock_sendto(s, b'test', addr)

asyncio.run(run())

uvloop == 0.20.0 response:
