Types

type HeightVoteSet 

type HeightVoteSet struct {
	// contains filtered or unexported fields
}

Keeps track of all VoteSets from round 0 to round 'round'.

Also keeps track of up to one RoundVoteSet greater than 'round' from each peer, to facilitate catchup syncing of commits.

A commit is +2/3 precommits for a block at a round, but which round is not known in advance, so when a peer provides a precommit for a round greater than mtx.round, we create a new entry in roundVoteSets but also remember the peer to prevent abuse. We let each peer provide us with up to 2 unexpected "catchup" rounds. One for their LastPrecommits round, and another for the official commit round.

func (*HeightVoteSet) AddVote

AddVote adds a vote of a specific type to the round Duplicate votes return added=false, err=nil.

func (*HeightVoteSet) GetVoteSet 

func (hvs *HeightVoteSet) GetVoteSet(round int32, voteType tmproto.SignedMsgType) *types.VoteSet
