Functions

func CanTry

func CanTry(maxAttempt int, chunk *ChunkStatus) bool

CanTry returns checks the history attempts and determine whether a chunk request can be tried again.

Types

type ChunkStatus

type ChunkStatus struct {
	Chunk             *flow.Chunk
	ExecutionResultID flow.Identifier
	ExecutorID        flow.Identifier
	LastAttempt       time.Time
	Attempt           int
}

func NewChunkStatus

func NewChunkStatus(chunk *flow.Chunk, resultID flow.Identifier,
	executorID flow.Identifier) *ChunkStatus

func (*ChunkStatus) Checksum

func (s *ChunkStatus) Checksum() flow.Identifier

func (*ChunkStatus) ID

func (s *ChunkStatus) ID() flow.Identifier

type Chunks

type Chunks struct {
	*stdmap.Backend
}

func NewChunks

func NewChunks(limit uint) *Chunks

func (*Chunks) Add

func (cs *Chunks) Add(chunk *ChunkStatus) bool

func (*Chunks) All

func (cs *Chunks) All() []*ChunkStatus

func (*Chunks) ByID

func (cs *Chunks) ByID(chunkID flow.Identifier) (*ChunkStatus, bool)

func (*Chunks) IncrementAttempt

func (cs *Chunks) IncrementAttempt(chunkID flow.Identifier) bool

func (*Chunks) Rem

func (cs *Chunks) Rem(chunkID flow.Identifier) bool

type Engine

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

Engine takes processable execution results, finds the chunks the are assigned to me, fetches the chunk data pack from execution nodes, and passes verifiable chunks to Verifier engine

func New

func New(
	log zerolog.Logger,
	metrics module.VerificationMetrics,
	tracer module.Tracer,
	net module.Network,
	me module.Local,
	results mempool.ResultDataPacks,
	chunkIdsByResult mempool.IdentifierMap,
	verifier network.Engine,
	assigner module.ChunkAssigner,
	state protocol.State,
	chunks *Chunks,
	headers storage.Headers,
	retryInterval time.Duration,
	maxAttempt int,
) (*Engine, error)

func (*Engine) Done

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

Done terminates the engine and returns a channel that is closed when the termination is done

func (*Engine) Process

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

Process processes the given event from the node with the given origin ID in a blocking manner. It returns the potential processing error when done.

func (*Engine) ProcessLocal

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

ProcessLocal processes an event originating on the local node. Note: this method is required as an Engine implementation, however it should not be invoked as match engine requires origin ID of events it receives. Use Process method instead.

func (*Engine) Ready

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

Ready initializes the engine and returns a channel that is closed when the initialization is done

func (*Engine) Submit

func (e *Engine) Submit(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.
