commit 491e20ae13c3acdd6d18d994cc41178733a778b5 Author: Nick Mathewson nickm@torproject.org Date: Tue Oct 11 11:47:13 2011 -0400
Change "reverse_lookup_name" functions to refer to "PTR_name"s
Under the new convention, having a tor_addr.*lookup function that doesn't do hostname resolution is too close for comfort.
I used this script here, and have made no other changes.
