commit 440eaa9b22573cdb0d38bf5c13200cc1077a453f
Author: George Kadianakis <desnac...@riseup.net>
Date: Thu Aug 3 16:08:17 2017 +0300
Correctly assign HSDir flags based on protocol list
In Nick's words:
"We want to always return false if the platform is a Tor version, and it
is not as new as 0.3.0.8 -- but if the platform is not a Tor version, or
if the version is as new as 0.3.0.8, then we want to obey the protocol
list.
That way, other implementations of our protocol won't have to claim any
particular Tor version, and future versions of Tor will have the freedom
to drop this protocol in the distant future."
