getaddrinfo for res in _socket.getaddrinfo error

[SalamanderSandwich]

Using dcc_send_and_get.py in examples with python 3.7.2 I get the following error. Works fine in 3.6.0.

INFO irc3d      Started

Not sure it's really related to irc3. Looks like it raise deep in asyncio.

And btw, are you sure you don't have a firewall or something ?

[gawel]

Also tests pass with 3.7 https://travis-ci.org/gawel/irc3/jobs/499987669 And, like other modules, the dcc part is well covered

Weird issue

[gawel]

Also tested locally:

$ .tox/py37/bin/python -V                          
Python 3.7.2+
$ .tox/py37/bin/python examples/dcc_send_and_get.py

Could this relate to ipv6?

[gawel]

Maybe. But the current traceback to show some 127.0.0.1

[kitten77]

Hmm pusseling, I know there is an issue if you try using dcc if you have connected with ipv6 to an ircd server.

[gawel]

Maybe it's possible to reproduce with irc3d (never tried to run it with ipv6)
