Functions

func Execute

func Execute(ctxt context.Context, cccid *ccprovider.CCContext, spec interface{}) (*pb.Response, *pb.ChaincodeEvent, error)

Execute - execute proposal, return original response of chaincode

func ExecuteChaincode

func ExecuteChaincode(ctxt context.Context, cccid *ccprovider.CCContext, args [][]byte) (*pb.Response, *pb.ChaincodeEvent, error)

ExecuteChaincode executes a given chaincode given chaincode name and arguments

func ExecuteWithErrorFilter

func ExecuteWithErrorFilter(ctxt context.Context, cccid *ccprovider.CCContext, spec interface{}) ([]byte, *pb.ChaincodeEvent, error)

ExecuteWithErrorFilter is similar to Execute, but filters error contained in chaincode response and returns Payload of response only. Mostly used by unit-test.

func GetCDSFromLSCC

func GetCDSFromLSCC(ctxt context.Context, txid string, signedProp *pb.SignedProposal, prop *pb.Proposal, chainID string, chaincodeID string) ([]byte, error)

GetCDSFromLSCC gets chaincode deployment spec from LSCC

func GetChaincodeDataFromLSCC

func GetChaincodeDataFromLSCC(ctxt context.Context, txid string, signedProp *pb.SignedProposal, prop *pb.Proposal, chainID string, chaincodeID string) (*ccprovider.ChaincodeData, error)

GetChaincodeDataFromLSCC gets chaincode data from LSCC given name

func HandleChaincodeStream

func HandleChaincodeStream(chaincodeSupport *ChaincodeSupport, ctxt context.Context, stream ccintf.ChaincodeStream) error

HandleChaincodeStream Main loop for handling the associated Chaincode stream

func IsDevMode

func IsDevMode() bool

IsDevMode returns true if the peer was configured with development-mode enabled

Types

type ChaincodeSupport

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

ChaincodeSupport responsible for providing interfacing with chaincodes from the Peer.

func GetChain

func GetChain() *ChaincodeSupport

GetChain returns the chaincode framework support object

func NewChaincodeSupport

func NewChaincodeSupport(getCCEndpoint func() (*pb.PeerEndpoint, error), userrunsCC bool, ccstartuptimeout time.Duration) *ChaincodeSupport

NewChaincodeSupport creates a new ChaincodeSupport instance

func (*ChaincodeSupport) Execute

func (chaincodeSupport *ChaincodeSupport) Execute(ctxt context.Context, cccid *ccprovider.CCContext, msg *pb.ChaincodeMessage, timeout time.Duration) (*pb.ChaincodeMessage, error)

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

func (*ChaincodeSupport) HandleChaincodeStream

func (chaincodeSupport *ChaincodeSupport) HandleChaincodeStream(ctxt context.Context, stream ccintf.ChaincodeStream) error

HandleChaincodeStream implements ccintf.HandleChaincodeStream for all vms to call with appropriate stream

func (*ChaincodeSupport) Launch

func (chaincodeSupport *ChaincodeSupport) Launch(context context.Context, cccid *ccprovider.CCContext, spec interface{}) (*pb.ChaincodeID, *pb.ChaincodeInput, error)

Launch 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.

func (*ChaincodeSupport) Stop

func (chaincodeSupport *ChaincodeSupport) Stop(context context.Context, cccid *ccprovider.CCContext, cds *pb.ChaincodeDeploymentSpec) error

Stop stops a chaincode if running

type DuplicateChaincodeHandlerError

type DuplicateChaincodeHandlerError struct {
	ChaincodeID *pb.ChaincodeID
}

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

func (*DuplicateChaincodeHandlerError) Error

func (d *DuplicateChaincodeHandlerError) Error() string

type Handler

type Handler struct {
	sync.RWMutex

	ChatStream  ccintf.ChaincodeStream
	FSM         *fsm.FSM
	ChaincodeID *pb.ChaincodeID
	// contains filtered or unexported fields
}

Handler responsible for management 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)
