Types ¶
type NewCollectorFactoryMethod ¶ added in v0.23.9
type NewCollectorFactoryMethod = func(view uint64, workers hotstuff.Workers) (hotstuff.VoteCollector, error)
NewCollectorFactoryMethod is a factory method to generate a VoteCollector for concrete view
type PendingStatus ¶
type PendingStatus struct {
// contains filtered or unexported fields
}
PendingStatus keeps track of pending votes for the same block
func NewPendingStatus ¶
func NewPendingStatus() *PendingStatus
NewPendingStatus creates a PendingStatus instance
type PendingVotes ¶
type PendingVotes struct {
// contains filtered or unexported fields
}
PendingVotes stores all the pending votes for different block proposals
func NewPendingVotes ¶
func NewPendingVotes() *PendingVotes
NewPendingVotes creates a PendingVotes instance
type VoteAggregator ¶
type VoteAggregator struct {
*component.ComponentManager
// contains filtered or unexported fields
}
VoteAggregator stores the votes and aggregates them into a QC when enough votes have been collected VoteAggregator is designed in a way that it can aggregate votes for collection & consensus clusters that is why implementation relies on dependency injection.
func NewVoteAggregator ¶ added in v0.23.9
func NewVoteAggregator( log zerolog.Logger, notifier hotstuff.Consumer, lowestRetainedView uint64, collectors hotstuff.VoteCollectors, ) (*VoteAggregator, error)
NewVoteAggregator creates an instance of vote aggregator Note: verifyingProcessorFactory is injected. Thereby, the code is agnostic to the different voting formats of main Consensus vs Collector consensus.
func (*VoteAggregator) AddBlock ¶ added in v0.23.9
func (va *VoteAggregator) AddBlock(block *model.Proposal) error
AddBlock notifies the VoteAggregator about a known block so that it can start processing pending votes whose block was unknown. It also verifies the proposer vote of a block, and return whether the proposer signature is valid. Expected error returns during normal operations: * model.InvalidBlockError if the proposer's vote for its own block is invalid * mempool.DecreasingPruningHeightError if the block's view has already been pruned
func (*VoteAggregator) AddVote ¶ added in v0.23.9
func (va *VoteAggregator) AddVote(vote *model.Vote)
AddVote checks if vote is stale and appends vote into processing queue actual vote processing will be called in other dispatching goroutine.
func (*VoteAggregator) InvalidBlock ¶ added in v0.23.9
func (va *VoteAggregator) InvalidBlock(proposal *model.Proposal) error
InvalidBlock notifies the VoteAggregator about an invalid proposal, so that it can process votes for the invalid block and slash the voters. Expected error returns during normal operations: * mempool.DecreasingPruningHeightError if proposal's view has already been pruned
func (*VoteAggregator) PruneUpToView ¶ added in v0.23.9
func (va *VoteAggregator) PruneUpToView(lowestRetainedView uint64)
PruneUpToView deletes all votes _below_ to the given view, as well as related indices. We only retain and process whose view is equal or larger than `lowestRetainedView`. If `lowestRetainedView` is smaller than the previous value, the previous value is kept and the method call is a NoOp.
type VoteCollectors ¶ added in v0.23.9
type VoteCollectors struct {
*component.ComponentManager
// contains filtered or unexported fields
}
VoteCollectors implements management of multiple vote collectors indexed by view. Implements hotstuff.VoteCollectors interface. Creating a VoteCollector for a particular view is lazy (instances are created on demand). This structure is concurrently safe.
func NewVoteCollectors ¶ added in v0.23.9
func NewVoteCollectors(logger zerolog.Logger, lowestRetainedView uint64, workerPool hotstuff.Workerpool, factoryMethod NewCollectorFactoryMethod) *VoteCollectors
func (*VoteCollectors) GetOrCreateCollector ¶ added in v0.23.9
func (v *VoteCollectors) GetOrCreateCollector(view uint64) (hotstuff.VoteCollector, bool, error)
GetOrCreateCollector retrieves the hotstuff.VoteCollector for the specified view or creates one if none exists.
- (collector, true, nil) if no collector can be found by the block ID, and a new collector was created.
- (collector, false, nil) if the collector can be found by the block ID
- (nil, false, error) if running into any exception creating the vote collector state machine
Expected error returns during normal operations:
- mempool.DecreasingPruningHeightError - in case view is lower than lowestRetainedView
func (*VoteCollectors) PruneUpToView ¶ added in v0.23.9
func (v *VoteCollectors) PruneUpToView(lowestRetainedView uint64)
PruneUpToView prunes the vote collectors with views _below_ the given value, i.e. we only retain and process whose view is equal or larger than `lowestRetainedView`. If `lowestRetainedView` is smaller than the previous value, the previous value is kept and the method call is a NoOp.
