New submission from Brent Gardner <bggard...@gmail.com>:
In Python 3.5.3, a socket with type AF_CAN returns a tuple in the form
`(interface, )` from getsockname(). In Python 3.7.3, getsockname() returns a
string (the name of the interface). The documentation states "a tuple is used
for the AF_CAN address family". The string will break code that worked in
3.5.3 by raising errors such as "Value Error: too many values to unpack
(expected 2)".
Example:
#3.5.3
import socket
s = socket.socket(socket.AF_CAN, socket.SOCK_RAW, socket.CAN_RAW)
s.bind(('vcan0',)) # requires tuple
s.getsockname() # returns tuple: ('vcan0', 29)
#3.7.3
import socket
s = socket.socket(socket.AF_CAN, socket.SOCK_RAW, socket.CAN_RAW)
s.bind(('vcan0',)) # requires tuple
s.getsockname() # returns string: 'vcan0'
