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 LastCommit round, and another for the official commit round.

func NewHeightVoteSet 

func NewHeightVoteSet(chainID string, height int64, valSet *types.ValidatorSet) *HeightVoteSet

func (*HeightVoteSet) AddVote 

func (hvs *HeightVoteSet) AddVote(vote *types.Vote, peerID p2p.ID) (added bool, err error)

Duplicate votes return added=false, err=nil. By convention, peerID is "" if origin is self.

func (*HeightVoteSet) Height 

func (hvs *HeightVoteSet) Height() int64

func (*HeightVoteSet) MarshalJSON 

func (hvs *HeightVoteSet) MarshalJSON() ([]byte, error)

func (*HeightVoteSet) POLInfo 

func (hvs *HeightVoteSet) POLInfo() (polRound int, polBlockID types.BlockID)

Last round and blockID that has +2/3 prevotes for a particular block or nil. Returns -1 if no such round exists.

func (*HeightVoteSet) Precommits 

func (hvs *HeightVoteSet) Precommits(round int) *types.VoteSet

func (*HeightVoteSet) Prevotes 

func (hvs *HeightVoteSet) Prevotes(round int) *types.VoteSet

func (*HeightVoteSet) Reset 

func (hvs *HeightVoteSet) Reset(height int64, valSet *types.ValidatorSet)

func (*HeightVoteSet) SetPeerMaj23 

func (hvs *HeightVoteSet) SetPeerMaj23(round int, type_ types.SignedMsgType, peerID p2p.ID, blockID types.BlockID) error

If a peer claims that it has 2/3 majority for given blockKey, call this. NOTE: if there are too many peers, or too much peer churn, this can cause memory issues. TODO: implement ability to remove peers too

func (hvs *HeightVoteSet) SetRound(round int)

Create more RoundVoteSets up to round.
