So after a good nights sleep: does it not make sense to use the canonical
hostname iff the name argument is not present / empty? Otherwise, fall back to
the documented steps? That way extra API is avoided, and I can't think of a
case where you would rather have
Stijn Hoop added the comment:
OK, fair enough.
From reading sources, it appears that hostname is using getaddrinfo(3) on
kernelhostname with hints-ai_flags AI_CANONNAME, while Lib/socket.py simply
uses gethostbyaddr(kernelhostname), and falls back on kernelhostname in case
of errors

Attached is a very lightly tested patch that matches hostname -f behaviour on
my system. I suspect this should be OK but it definitely needs more testing
than just my system...

OK, dumping my current findings here, as I'm still not sure what the expected
results should be.
First of all, Lib/socket.py calls gethostbyaddr with a name. As in, gethostby
_ADDR_ with a name.
This works because Modules/socketmodule.c internally uses setipaddr

Still seeing this on Fedora 18 / Python 2.7.3.
I only have loopback in /etc/hosts
[TUE\shoop@pclin281] ~ cat /etc/hosts
127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4
::1 localhost localhost.localdomain localhost6 localhost6
