commit 6094a886cf9be92d29077b428554a75c9971a2ca Author: teor (Tim Wilson-Brown) <teor2345@gmail.com> Date: Mon Jan 18 14:00:29 2016 +1100 Check ORPort and DirPort reachability before publishing a relay descriptor Otherwise, relays publish a descriptor with DirPort 0 when the DirPort reachability test takes longer than the ORPort reachability test. Closes bug #18050. Reported by "starlight", patch by "teor".
