New submission from Andrew Grover :
RDS is a reliable datagram protocol used by Oracle clusters for inter-process
communication. It is in the Linux kernel, and has a defined address family
number. Its use is identical to UDP, except the address family is 21, and the
type is SOCK_SEQPACKET.
So, what's this got to do with Python? :)
Apparently Modules/socketmodule.c getsockaddrarg() checks bind() args, and only
allows known socket types to bind. Attempting to bind with an RDS socket fails.
It looks pretty straightforward to add support for a new family, but before
doing so I wanted to check whether this was likely to be accepted, and also to
ask if it wouldn't make more sense for getsockaddrarg() to not default to
failing unknown families, but instead letting them through? If the params are
wrong for a non-enumerated family, bind() will presumably return an error that
the user will get.
