Method serialSendAsync

core/chaincode/handler.go:357–373

serialSendAsync serves the same purpose as serialSend (serialize msgs so gRPC will be happy). In addition, it is also asynchronous so send-remoterecv--localrecv loop can be nonblocking. Only errors need to be handled and these are handled by communication on supplied error channel. A typical use wil

(msg *pb.ChaincodeMessage)

// communication on supplied error channel. A typical use will be a non-blocking or
// nil channel
func (h *Handler) serialSendAsync(msg *pb.ChaincodeMessage) {
	go func() {
		if err := h.serialSend(msg); err != nil {
			// provide an error response to the caller
			resp := &pb.ChaincodeMessage{
				Type:      pb.ChaincodeMessage_ERROR,
				Payload:   []byte(err.Error()),
				Txid:      msg.Txid,
				ChannelId: msg.ChannelId,
			}
			h.Notify(resp)

			// surface send error to stream processing
			h.errChan <- err
		}
	}()
}

// Check if the transactor is allow to call this chaincode on this channel
func (h *Handler) checkACL(signedProp *pb.SignedProposal, proposal *pb.Proposal, ccIns *sysccprovider.ChaincodeInstance) error {
