sock_connect: TypeError: getaddrinfo() takes exactly 2 positional arguments (4 given)

• uvloop version: 0.8.0
• Python version: 3.6.0
• Platform: Linux
• Can you reproduce the bug with PYTHONASYNCIODEBUG in env?: yes

The following program fails when executed with uvloop (works fine with asyncio):

import asyncio
import socket
import uvloop

asyncio.set_event_loop_policy(uvloop.EventLoopPolicy())
loop = asyncio.get_event_loop()
sock = socket.socket(socket.AF_INET6, socket.SOCK_STREAM)
sock.setblocking(False)
loop.run_until_complete(loop.sock_connect(sock, ('::1', 22, 0, 0)))
loop.close()

Traceback (most recent call last):
  File "tmp.py", line 9, in <module>
    loop.run_until_complete(loop.sock_connect(sock, ('::1', 22, 0, 0)))

It works in asyncio by pure accident: https://github.com/python/cpython/blob/master/Lib/asyncio/base_events.py#L163

Please fix your program, as asyncio will raise the same error in Python 3.7.

My mistake. After some testing with IPv6 connections I confirm this is a bug in uvloop.

Fixed. Will be shipped in uvloop 0.9.0 soon.

Please try uvloop v0.9.0.
