Functions

func NewHTTPServer

func NewHTTPServer(
	grpcServer *grpc.Server,
	address string,
) *http.Server

NewHTTPServer creates and intializes a new HTTP GRPC proxy server

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
	StateStreamListenAddr     string                           // the state stream 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                int                              // GRPC max message size
	MaxExecutionDataMsgSize   int                              // GRPC max message size for block execution data
	ExecutionClientTimeout    time.Duration                    // execution API GRPC client timeout

	PreferredExecutionNodeIDs []string                         // preferred list of upstream execution node IDs
	FixedExecutionNodeIDs     []string                         // fixed list of execution node IDs to choose from if no node node ID can be chosen from the PreferredExecutionNodeIDs
}

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 {
	// 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) Done

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

Done returns a done channel that is closed once the engine has fully stopped. It sends a signal to stop the gRPC server, then closes the channel.

func (*Engine) Ready

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

Ready returns a ready channel that is closed once the engine has fully started. The RPC engine is ready when the gRPC server has successfully started.

func (*Engine) RestApiAddress

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

func (*Engine) SecureGRPCAddress

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

func (*Engine) SubmitLocal

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

SubmitLocal submits an event originating on the local node.

func (*Engine) UnsecureGRPCAddress

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

type HTTPHeader

type HTTPHeader struct {
	Key   string
	Value string
}

type RPCEngineBuilder

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

	state protocol.State,
	config Config,
	collectionRPC accessproto.AccessAPIClient,

	apiRatelimits map[string]int,
	apiBurstLimits map[string]int,
) (*RPCEngineBuilder, error)

NewBuilder returns a new RPC engine builder.

func NewRPCEngineBuilder

func NewRPCEngineBuilder(engine *Engine) *RPCEngineBuilder

NewRPCEngineBuilder helps to build a new RPC engine.

func (*RPCEngineBuilder) Build

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

func (*RPCEngineBuilder) Handler

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

func (*RPCEngineBuilder) WithBlockSignerDecoder

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

func (builder *RPCEngineBuilder) WithLegacy() *RPCEngineBuilder

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

func (*RPCEngineBuilder) WithMetrics

func (builder *RPCEngineBuilder) WithMetrics() *RPCEngineBuilder

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

func (*RPCEngineBuilder) WithNewHandler

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.
