[tor-commits] [metrics-db/master] Download votes of all known authorities.
commit b75f6809502952760b0c7426d867f3817a54d1c1
Author: Karsten Loesing <karsten.loesing@xxxxxxx>
Date: Sat Oct 27 18:05:34 2012 -0400
Download votes of all known authorities.
We currently look at the downloaded consensus to decide which votes to
download. This approach fails when we're missing a consensus. Instead,
download votes published by all known authorities, not just the ones
contained in the consensus. Implements #5812.
