Types

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(
	logger zerolog.Logger,
	net network.Network,
	me module.Local,
	request module.Requester,
	state protocol.State,
	headers storage.Headers,
	blocks storage.Blocks,
	collections storage.Collections,
	events storage.Events,
	serviceEvents storage.ServiceEvents,
	transactionResults storage.TransactionResults,
	executionEngine computation.ComputationManager,
	providerEngine provider.ProviderEngine,
	execState state.ExecutionState,
	metrics module.ExecutionMetrics,
	tracer module.Tracer,
	extLog bool,
	checkAuthorizedAtBlock func(blockID flow.Identifier) (bool, error),
	pruner *pruner.Pruner,
	uploader *uploader.Manager,
	stopControl *stop.StopControl,
	onflowOnlyLNs bool,
) (*Engine, error)

func (*Engine) BlockProcessable

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) ExecuteScriptAtBlockID

func (e *Engine) ExecuteScriptAtBlockID(
	ctx context.Context,
	script []byte,
	arguments [][]byte,
	blockID flow.Identifier,
) ([]byte, error)

func (*Engine) GetAccount

func (e *Engine) GetAccount(
	ctx context.Context,
	addr flow.Address,
	blockID flow.Identifier,
) (*flow.Account, error)

func (*Engine) GetRegisterAtBlockID

func (e *Engine) GetRegisterAtBlockID(
	ctx context.Context,
	owner, key []byte,
	blockID flow.Identifier,
) ([]byte, error)

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 IngestRPC

type IngestRPC interface {

	// ExecuteScriptAtBlockID executes a script at the given Block id
	ExecuteScriptAtBlockID(ctx context.Context, script []byte, arguments [][]byte, blockID flow.Identifier) ([]byte, error)

	// GetAccount returns the Account details at the given Block id
	GetAccount(ctx context.Context, address flow.Address, blockID flow.Identifier) (*flow.Account, error)

	// GetRegisterAtBlockID returns the value of a register at the given Block id (if available)
	GetRegisterAtBlockID(ctx context.Context, owner, key []byte, blockID flow.Identifier) ([]byte, error)
}

IngestRPC represents the RPC calls that the execution ingest engine exposes to support the Access Node API calls

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
