[New-bugs-announce] [issue27816] sock.proto does not reflect actual protocol

[Christian Heimes]

New submission from Christian Heimes:

The proto property of a socket object does not reflect the actual protocol of the socket file descriptor:

>>> import socket
>>> SO_PROTOCOL = getattr(socket, 'SO_PROTOCOL', 38)
>>> tcp = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
>>> tcp.proto
0
>>> tcp.getsockopt(socket.SOL_SOCKET, SO_PROTOCOL)
6
>>> socket.getprotobyname('tcp')
6
