Types

type Config

type Config struct {
	UnsecureGRPCListenAddr    string                           // the non-secure GRPC server address as ip:port
	SecureGRPCListenAddr      string                           // the secure GRPC server address as ip:port
	TransportCredentials      credentials.TransportCredentials // the secure GRPC credentials
	HTTPListenAddr            string                           // the HTTP web proxy address as ip:port
	RESTListenAddr            string                           // the REST server address as ip:port (if empty the REST server will not be started)
	CollectionAddr            string                           // the address of the upstream collection node
	HistoricalAccessAddrs     string                           // the list of all access nodes from previous spork
	MaxMsgSize                uint                             // GRPC max message size
	ExecutionClientTimeout    time.Duration                    // execution API GRPC client timeout

	FixedExecutionNodeIDs     []string                         // fixed list of execution node IDs to choose from if no node node ID can be chosen from the PreferredExecutionNodeIDs
	ArchiveAddressList        []string                         // the archive node address list to send script executions. when configured, script executions will be all sent to the archive node
}

Config defines the configurable options for the access node server A secure GRPC server here implies a server that presents a self-signed TLS certificate and a client that authenticates the server via a pre-shared public key

type Engine

type Engine struct {
	component.Component
	// contains filtered or unexported fields
}

Engine exposes the server with a simplified version of the Access API. An unsecured GRPC server (default port 9000), a secure GRPC server (default port 9001) and an HTTP Web proxy (default port 8000) are brought up.

func (*Engine) OnFinalizedBlock added in v0.31.0

func (e *Engine) OnFinalizedBlock(block *model.Block)

OnFinalizedBlock responds to block finalization events.

func (*Engine) RestApiAddress added in v0.23.2

func (e *Engine) RestApiAddress() net.Addr

RestApiAddress returns the listen address of the REST API server. Guaranteed to be non-nil after Engine.Ready is closed.

func (*Engine) SecureGRPCAddress added in v0.20.0

func (e *Engine) SecureGRPCAddress() net.Addr

SecureGRPCAddress returns the listen address of the secure GRPC server. Guaranteed to be non-nil after Engine.Ready is closed.

func (*Engine) UnsecureGRPCAddress added in v0.20.0

func (e *Engine) UnsecureGRPCAddress() net.Addr

UnsecureGRPCAddress returns the listen address of the unsecure GRPC server. Guaranteed to be non-nil after Engine.Ready is closed.

type HTTPHeader

type HTTPHeader struct {
	Key   string
	Value string
}

type RPCEngineBuilder added in v0.27.0

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

func NewBuilder added in v0.27.0

func NewBuilder(log zerolog.Logger,
	state protocol.State,
	config Config,
	collectionRPC accessproto.AccessAPIClient,
	historicalAccessNodes []accessproto.AccessAPIClient,
	blocks storage.Blocks,
	headers storage.Headers,
	collections storage.Collections,
	transactions storage.Transactions,
	executionReceipts storage.ExecutionReceipts,
	executionResults storage.ExecutionResults,
	chainID flow.ChainID,
	accessMetrics module.AccessMetrics,
	collectionGRPCPort uint,
	executionGRPCPort uint,
	retryEnabled bool,
	rpcMetricsEnabled bool,
	apiRatelimits map[string]int,
	apiBurstLimits map[string]int,
	me module.Local,
) (*RPCEngineBuilder, error)

NewBuilder returns a new RPC engine builder.

func NewRPCEngineBuilder added in v0.27.0

func NewRPCEngineBuilder(engine *Engine, me module.Local, finalizedHeaderCache module.FinalizedHeaderCache) *RPCEngineBuilder

NewRPCEngineBuilder helps to build a new RPC engine.

func (*RPCEngineBuilder) Build added in v0.27.0

func (builder *RPCEngineBuilder) Build() (*Engine, error)

func (*RPCEngineBuilder) Handler added in v0.28.0

func (builder *RPCEngineBuilder) Handler() accessproto.AccessAPIServer

func (*RPCEngineBuilder) WithBlockSignerDecoder added in v0.27.0

func (builder *RPCEngineBuilder) WithBlockSignerDecoder(signerIndicesDecoder hotstuff.BlockSignerDecoder) *RPCEngineBuilder

WithBlockSignerDecoder specifies that signer indices in block headers should be translated to full node IDs with the given decoder. Caution: you can inject either a `BlockSignerDecoder` (via method `WithBlockSignerDecoder`) or an `AccessAPIServer` (via method `WithNewHandler`); but not both. If both are specified, the builder will error during the build step.

Returns self-reference for chaining.

func (*RPCEngineBuilder) WithLegacy added in v0.27.0

func (builder *RPCEngineBuilder) WithLegacy() *RPCEngineBuilder

WithLegacy specifies that a legacy access API should be instantiated Returns self-reference for chaining.

func (*RPCEngineBuilder) WithMetrics added in v0.27.0

func (builder *RPCEngineBuilder) WithMetrics() *RPCEngineBuilder

WithMetrics specifies the metrics should be collected. Returns self-reference for chaining.

func (*RPCEngineBuilder) WithNewHandler added in v0.27.0

func (builder *RPCEngineBuilder) WithNewHandler(handler accessproto.AccessAPIServer) *RPCEngineBuilder

WithNewHandler specifies that the given `AccessAPIServer` should be used for serving API queries. Caution: you can inject either a `BlockSignerDecoder` (via method `WithBlockSignerDecoder`) or an `AccessAPIServer` (via method `WithNewHandler`); but not both. If both are specified, the builder will error during the build step.

Returns self-reference for chaining.
