commit d68bbb0a2939927eef221d8f9543a016f2c88245
Author: teor <teor2345(a)gmail.com>
Date: Wed Apr 15 19:02:29 2015 +1000
Unit tests for consider_adding_dir_servers() as modified in #15642
Unit tests for the 10 valid combinations of set/NULL config options
DirAuthorities, AlternateBridgeAuthority, AlternateDirAuthority,
and FallbackDir.
Add assertion in consider_adding_dir_servers() for checks in
validate_dir_servers():
"You cannot set both DirAuthority and Alternate*Authority."
