Functions

func Execute

func Execute(ctxt context.Context, chain *ChaincodeSupport, t *pb.Transaction) ([]byte, error)

Execute - execute transaction or a query

func ExecuteTransactions

func ExecuteTransactions(ctxt context.Context, cname ChainName, xacts []*pb.Transaction) ([]byte, []error)

ExecuteTransactions - will execute transactions on the array one by one will return an array of errors one for each transaction. If the execution succeeded, array element will be nil. returns state hash

func HandleChaincodeStream

func HandleChaincodeStream(chaincodeSupport *ChaincodeSupport, stream pb.ChaincodeSupport_RegisterServer) error

HandleChaincodeStream Main loop for handling the associated Chaincode stream

func SetupTestConfig

func SetupTestConfig()

SetupTestConfig setup the config during test execution

func SetupTestLogging

func SetupTestLogging()

SetupTestLogging setup the logging during test execution

Types

type ChainName

type ChainName string

ChainName is the name of the chain to which this chaincode support belongs to.

type ChaincodeSupport

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

ChaincodeSupport responsible for providing interfacing with chaincodes from the Peer.

func GetChain

func GetChain(name ChainName) *ChaincodeSupport

GetChain returns the chaincode support for a given chain

func NewChaincodeSupport

func NewChaincodeSupport(chainname ChainName, getPeerEndpoint func() (*pb.PeerEndpoint, error), userrunsCC bool, ccstartuptimeout time.Duration, secHelper crypto.Peer) *ChaincodeSupport

NewChaincodeSupport creates a new ChaincodeSupport instance

func (*ChaincodeSupport) DeployChaincode

func (chaincodeSupport *ChaincodeSupport) DeployChaincode(context context.Context, t *pb.Transaction) (*pb.ChaincodeDeploymentSpec, error)

DeployChaincode deploys the chaincode if not in development mode where user is running the chaincode.

func (*ChaincodeSupport) Execute

func (chaincodeSupport *ChaincodeSupport) Execute(ctxt context.Context, chaincode string, msg *pb.ChaincodeMessage, timeout time.Duration, tx *pb.Transaction) (*pb.ChaincodeMessage, error)

Execute executes a transaction and waits for it to complete until a timeout value.

func (*ChaincodeSupport) GetExecutionContext

func (chaincodeSupport *ChaincodeSupport) GetExecutionContext(context context.Context, requestContext *pb.ChaincodeRequestContext) (*pb.ChaincodeExecutionContext, error)

GetExecutionContext returns the execution context. DEPRECATED. TO be removed.

func (*ChaincodeSupport) LaunchChaincode

func (chaincodeSupport *ChaincodeSupport) LaunchChaincode(context context.Context, t *pb.Transaction) (*pb.ChaincodeID, *pb.ChaincodeInput, error)

LaunchChaincode will launch the chaincode if not running (if running return nil) and will wait for handler of the chaincode to get into FSM ready state.

func (*ChaincodeSupport) Register

func (chaincodeSupport *ChaincodeSupport) Register(stream pb.ChaincodeSupport_RegisterServer) error

Register the bidi stream entry point called by chaincode to register with the Peer.

type Config

type Config struct {
}

Config the config wrapper structure

type DuplicateChaincodeHandlerError

type DuplicateChaincodeHandlerError struct {
	ChaincodeID *pb.ChaincodeID
}

DuplicateChaincodeHandlerError returned if attempt to register same chaincodeID while a stream already exists.

func (*DuplicateChaincodeHandlerError) Error

type Handler

type Handler struct {
	sync.RWMutex
	ChatStream  PeerChaincodeStream
	FSM         *fsm.FSM
	ChaincodeID *pb.ChaincodeID
	// contains filtered or unexported fields
}

Handler responsbile for managment of Peer's side of chaincode stream

func (*Handler) HandleMessage

func (handler *Handler) HandleMessage(msg *pb.ChaincodeMessage) error

HandleMessage implementation of MessageHandler interface. Peer's handling of Chaincode messages.

type MessageHandler

type MessageHandler interface {
	HandleMessage(msg *pb.ChaincodeMessage) error
	SendMessage(msg *pb.ChaincodeMessage) error
}

MessageHandler interface for handling chaincode messages (common between Peer chaincode support and chaincode)

type PeerChaincodeStream

type PeerChaincodeStream interface {
	Send(*pb.ChaincodeMessage) error
	Recv() (*pb.ChaincodeMessage, error)
}

PeerChaincodeStream interface for stream between Peer and chaincode instance.
