Types

type BlockLoader added in v0.32.0

type BlockLoader interface {
	LoadUnexecuted(ctx context.Context) ([]flow.Identifier, error)
}

type CollectionFetcher added in v0.32.0

type CollectionFetcher interface {
	// FetchCollection decides which collection nodes to fetch the collection from
	// No error is expected during normal operation
	FetchCollection(blockID flow.Identifier, height uint64, guarantee *flow.CollectionGuarantee) error

	// Force forces the requests to be sent immediately
	Force()
}

CollectionFetcher abstracts the details of how to fetch collection

type Engine

type Engine struct {
	psEvents.Noop // satisfy protocol events consumer interface
	// contains filtered or unexported fields
}

An Engine receives and saves incoming blocks.

func New

func New(
	unit *engine.Unit,
	logger zerolog.Logger,
	net network.EngineRegistry,
	me module.Local,
	collectionFetcher CollectionFetcher,
	headers storage.Headers,
	blocks storage.Blocks,
	collections storage.Collections,
	executionEngine computation.ComputationManager,
	providerEngine provider.ProviderEngine,
	execState state.ExecutionState,
	metrics module.ExecutionMetrics,
	tracer module.Tracer,
	extLog bool,
	pruner *pruner.Pruner,
	uploader *uploader.Manager,
	stopControl *stop.StopControl,
	loader BlockLoader,
) (*Engine, error)

func (*Engine) BlockProcessable added in v0.10.0

func (e *Engine) BlockProcessable(b *flow.Header, _ *flow.QuorumCertificate)

BlockProcessable handles the new verified blocks (blocks that have passed consensus validation) received from the consensus nodes NOTE: BlockProcessable might be called multiple times for the same block. NOTE: Ready calls reloadUnexecutedBlocks during initialization, which handles dropped protocol events.

func (*Engine) Done

func (e *Engine) Done() <-chan struct{}

Done returns a channel that will close when the engine has successfully stopped.

func (*Engine) OnCollection

func (e *Engine) OnCollection(originID flow.Identifier, entity flow.Entity)

OnCollection is a callback for handling the collections requested by the collection requester.

func (*Engine) Process

func (e *Engine) Process(
	channel channels.Channel,
	originID flow.Identifier,
	event interface{},
) error

func (*Engine) ProcessLocal

func (e *Engine) ProcessLocal(event interface{}) error

ProcessLocal processes an event originating on the local node.

func (*Engine) Ready

func (e *Engine) Ready() <-chan struct{}

Ready returns a channel that will close when the engine has successfully started.

func (*Engine) Submit

func (e *Engine) Submit(
	channel channels.Channel,
	originID flow.Identifier,
	event interface{},
)

Submit submits the given event from the node with the given origin ID for processing in a non-blocking manner. It returns instantly and logs a potential processing error internally when done.

func (*Engine) SubmitLocal

func (e *Engine) SubmitLocal(event interface{})

SubmitLocal submits an event originating on the local node.

type Mempool

type Mempool struct {
	ExecutionQueue    *stdmap.Queues
	BlockByCollection *stdmap.BlockByCollections
}

func (*Mempool) Run

func (m *Mempool) Run(f func(blockByCollection *stdmap.BlockByCollectionBackdata, executionQueue *stdmap.QueuesBackdata) error) error
