[New-bugs-announce] [issue41169] socket.inet_pton raised when pass an IPv6 address like "[::]" to it

[Wator Sead]

New submission from Wator Sead <seahoh at gmail.com>:

3.6:

>>> import socket
>>> socket.inet_pton(socket.AF_INET6,'[::]')
b'\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00'


3.7 and above:

>>> import socket
>>> socket.inet_pton(socket.AF_INET6,'[::]')
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
OSError: illegal IP address string passed to inet_pton


Both:

>>> import socket
>>> addr = '[::1]', 888
>>> ls = socket.socket(socket.AF_INET6)
>>> cs = socket.socket(socket.AF_INET6)
>>> ls.bind(addr)  # no raise
>>> ls.listen(1)
>>> cs.connect(addr)  # no raise
