commit df42eb0a18a9f6fe4b729a1c9a63bb6ab247f631 Author: Sebastian Hahn <sebastian(a)torproject.org> Date: Thu Jun 2 13:30:32 2011 +0200 Fix unit test failure in dir/formats options->DirPort is 0 in the unit tests, so router_get_advertised_dir_port() would return 0 so we wouldn't pick a dirport. This isn't what we want for the unit tests.
