[patch] create_default_site: configurable default domain name

[Etienne Robillard]

Hi,

The create_default_site function in the django.contrib.sites.management
module hardcodes example.com as the default site. I think this is potentially
harmful for users because it can be exploited remotely.

A better hardcoded value would be to use 'localhost' or socket.gethostname
as the default domain name. The attached patch implements the later for resolving
the default domain name.

Uses socket.gethostname to resolve the default domain name

Since example.com is explicitly reserved in RFC 2606, it's not open to any kind of effective exploitation.

In future, perhaps you could have researched this rather than calling the developers stupid in the patch. Just a thought.
