Types ¶
type CleanupFunc ¶
type CleanupFunc func(blockID flow.Identifier) error
CleanupFunc is called after a block was finalized to allow other components to execute cleanup operations.
func CleanupMempools ¶
func CleanupMempools( collector module.MempoolMetrics, spans module.ConsensusMetrics, payloads storage.Payloads, guarantees mempool.Guarantees, seals mempool.IncorporatedResultSeals) CleanupFunc
func CleanupNothing ¶
func CleanupNothing() CleanupFunc
type Finalizer ¶
type Finalizer struct {
// contains filtered or unexported fields
}
Finalizer is a simple wrapper around our temporary state to clean up after a block has been fully finalized to the persistent protocol state.
func NewFinalizer ¶
func NewFinalizer(db *badger.DB, headers storage.Headers, state protocol.FollowerState, tracer module.Tracer, options ...func(*Finalizer)) *Finalizer
NewFinalizer creates a new finalizer for the temporary state.
func (*Finalizer) MakeFinal ¶
func (f *Finalizer) MakeFinal(blockID flow.Identifier) error
MakeFinal will finalize the block with the given ID and clean up the memory pools after it.
This assumes that guarantees and seals are already in persistent state when included in a block proposal. Between entering the non-finalized chain state and being finalized, entities should be present in both the volatile memory pools and persistent storage. No errors are expected during normal operation.
