commit 0e1fad648d22923d7455b94734df36585b8f624f Author: Nick Mathewson nickm@torproject.org Date: Tue May 24 11:55:08 2011 -0400

Don't try to build descriptors when router_get_advertised_or_port()==0

The previous attempt was incomplete: it told us not to publish a descriptor, but didn't stop us from generating one. Now we treat an absent OR port the same as not knowing our address. (This means that when we _do_ get an OR port, we need to mark the descriptor dirty.)
