commit e167910fce2b83d9de3a252cdf02cabdafced14b
Author: Roger Dingledine <a...@torproject.org>
Date: Fri Mar 11 10:40:31 2016 -0500
rip out hid_serv_responsible_for_desc_id()
This simplifies relay behavior, because the relay offers the hsdir
functionality independent of whether the directory authorities have
decided this relay is suitable for clients to use yet.
Implements ticket 18332.

+ o Removed features:
+ - Streamline relay-side hsdir handling: when relays consider whether
+ to accept an uploaded hidden service descriptor, they no longer
+ check whether directory authorities think they deserve the HSDir
+ flag, or whether they are one of the relays in the network that is
+ "supposed" to handle that descriptor. Implements ticket 18332.
