Proposed fix: pass the entire ip tuple (from getaddrinfo) to
is_loopback_ip_address, and maybe (for backward compatibility in case any app
is using it?) test the type of the argument. Or something.
So, change:
options.ips = list(set([
ip[4][0] for ip in socket.getaddrinfo(socket.getfqdn(), 0)
if not is_loopback_ip_address(ip[4][0])]))
to
options.ips = list(set([
addrinfo[4][0] for addrinfo in socket.getaddrinfo(socket.getfqdn(),
None)
if not is_loopback_ip_address(addrinfo=addrinfo)]))
and change:
def is_loopback_ip_address(ip):
"""Determines whether the IP address appears to be a loopback address.
This assumes that the IP is valid. The IPv6 check is limited to '::1'.
"""
if not ip:
return False
if ip.count('.') == 3: # IPv4
return ip.startswith('127') or ip.startswith('::ffff:127')
return ip == '::1' # IPv6
to:
def is_loopback_ip_address(ip=None, addrinfo=None):
"""Determines whether the address appears to be an IP loopback address.
This assumes that the IP is valid. The IPv6 check is limited to '::1'.
addrinfo is a tuple from socket.getaddrinfo()
"""
if addrinfo and addrinfo[0] == socket.AF_INET or addrinfo[0] ==
socket.AF_INET6:
ip = addrinfo[4]
if not ip:
return False
if ip.count('.') == 3: # IPv4
return ip.startswith('127') or ip.startswith('::ffff:127')
return ip == '::1' # IPv6
