commit cdbb85ee3def5cc908c7f84948edb22be7351f84 Author: Karsten Loesing karsten.loesing@gmx.net Date: Tue Jan 28 11:28:59 2014 +0100

Make it clearer that authorities scan other votes.

See git commits 2e692bd8 and eaf5487d, which went into 0.2.2.12-alpha: o Major bugfixes: - Many relays have been falling out of the consensus lately because not enough authorities know about their descriptor for them to get a majority of votes. When we deprecated the v2 directory protocol, we got rid of the only way that v3 authorities can hear from each other about other descriptors. Now authorities examine every v3 vote for new descriptors, and fetch them from that authority. Bugfix on 0.2.1.23.

Section 3.6 already says this implicitly when specifying how authorities download missing router descriptors, but that doesn't mean we can't also make it more explicit when specifying how authorities exchange votes. --- dir-spec.txt | 7 +++++++ 1 file changed, 7 insertions(+)
