Functions

func CacheConfiguration

func CacheConfiguration() (err error)

CacheConfiguration computes and caches commonly-used constants and computed constants as package variables. Routines which were previously global have been embedded here to preserve the original abstraction.

func CreateChainFromBlock

func CreateChainFromBlock(cb *common.Block, ccp ccprovider.ChaincodeProvider, sccp sysccprovider.SystemChaincodeProvider) error

CreateChainFromBlock creates a new chain from config block

func GetChannelConfig

func GetChannelConfig(cid string) channelconfig.Resources

GetChannelConfig returns the channel configuration of the chain with channel ID. Note that this call returns nil if chain cid has not been created.

func GetChannelsInfo

func GetChannelsInfo() []*pb.ChannelInfo

GetChannelsInfo returns an array with information about all channels for this peer

func GetClientCertificate

func GetClientCertificate() (tls.Certificate, error)

GetClientCertificate returns the TLS certificate to use for gRPC client connections

func GetCurrConfigBlock

func GetCurrConfigBlock(cid string) *common.Block

GetCurrConfigBlock returns the cached config block of the specified chain. Note that this call returns nil if chain cid has not been created.

func GetLedger

func GetLedger(cid string) ledger.PeerLedger

GetLedger returns the ledger of the chain with chain ID. Note that this call returns nil if chain cid has not been created.

func GetLocalAddress

func GetLocalAddress() (string, error)

GetLocalAddress returns the peer.address property

func GetLocalIP

func GetLocalIP() string

GetLocalIP returns the non loopback local IP of the host

func GetMSPIDs

func GetMSPIDs(cid string) []string

GetMSPIDs returns the ID of each application MSP defined on this chain

func GetPeerEndpoint

func GetPeerEndpoint() (*pb.PeerEndpoint, error)

GetPeerEndpoint returns peerEndpoint from cached configuration

func GetPolicyManager

func GetPolicyManager(cid string) policies.Manager

GetPolicyManager returns the policy manager of the chain with chain ID. Note that this call returns nil if chain cid has not been created.

func GetServerConfig

func GetServerConfig() (comm.ServerConfig, error)

GetServerConfig returns the gRPC server configuration for the peer

func GetServerRootCAs

func GetServerRootCAs() ([][]byte, error)

GetServerRootCAs returns the root certificates which will be trusted for gRPC client connections to peers and orderers.

func GetStableChannelConfig

func GetStableChannelConfig(cid string) channelconfig.Resources

GetStableChannelConfig returns the stable channel configuration of the chain with channel ID. Note that this call returns nil if chain cid has not been created.

func InitChain

func InitChain(cid string)

InitChain takes care to initialize chain after peer joined, for example deploys system CCs

func Initialize

func Initialize(init func(string), ccp ccprovider.ChaincodeProvider, sccp sysccprovider.SystemChaincodeProvider,
	pm txvalidator.PluginMapper, pr *platforms.Registry, deployedCCInfoProvider ledger.DeployedChaincodeInfoProvider,
	membershipProvider ledger.MembershipInfoProvider, metricsProvider metrics.Provider)

Initialize sets up any chains that the peer has from the persistence. This function should be called at the start up when the ledger and gossip ready

func MockCreateChain

func MockCreateChain(cid string) error

MockCreateChain used for creating a ledger for a chain for tests without having to join

func MockInitialize

func MockInitialize()

MockInitialize resets chains for test env

func MockSetMSPIDGetter

func MockSetMSPIDGetter(mspIDGetter func(string) []string)

func NewChannelPolicyManagerGetter

func NewChannelPolicyManagerGetter() policies.ChannelPolicyManagerGetter

NewChannelPolicyManagerGetter returns a new instance of ChannelPolicyManagerGetter

func NewConfigSupport

func NewConfigSupport() cc.Manager

NewConfigSupport returns

func NewDeliverEventsServer

func NewDeliverEventsServer(mutualTLS bool, policyCheckerProvider PolicyCheckerProvider, chainManager deliver.ChainManager, metricsProvider metrics.Provider) peer.DeliverServer

NewDeliverEventsServer creates a peer.Deliver server to deliver block and filtered block events

func NewPeerServer

func NewPeerServer(listenAddress string, serverConfig comm.ServerConfig) (*comm.GRPCServer, error)

NewPeerServer creates an instance of comm.GRPCServer This server is used for peer communications

func SetCurrConfigBlock

func SetCurrConfigBlock(block *common.Block, cid string) error

SetCurrConfigBlock sets the current config block of the specified channel

Types

type CollectionSupport

type CollectionSupport struct {
	ledger.PeerLedger
}

TODO: Remove CollectionSupport and respective methonds on them. CollectionSupport is created per chain and is passed to the simple collection store and the gossip. As it is created per chain, there is no need to pass the channelID for both GetQueryExecutorForLedger() and GetIdentityDeserializer(). Note that the cid passed to GetQueryExecutorForLedger is never used. Instead, we can directly pass the ledger.PeerLedger and msp.IdentityDeserializer to the simpleCollectionStore and pass only the msp.IdentityDeserializer to the gossip in createChain() -- FAB-13037

func (*CollectionSupport) GetIdentityDeserializer

func (*CollectionSupport) GetIdentityDeserializer(chainID string) msp.IdentityDeserializer

func (*CollectionSupport) GetQueryExecutorForLedger

func (cs *CollectionSupport) GetQueryExecutorForLedger(cid string) (ledger.QueryExecutor, error)

type DeliverChainManager

type DeliverChainManager struct {
}

DeliverChainManager provides access to a channel for performing deliver

func (DeliverChainManager) GetChain

func (DeliverChainManager) GetChain(chainID string) deliver.Chain

type Operations

type Operations interface {
	CreateChainFromBlock(cb *common.Block, ccp ccprovider.ChaincodeProvider, sccp sysccprovider.SystemChaincodeProvider) error
	GetChannelConfig(cid string) channelconfig.Resources
	GetChannelsInfo() []*pb.ChannelInfo
	GetCurrConfigBlock(cid string) *common.Block
	GetLedger(cid string) ledger.PeerLedger
	GetMSPIDs(cid string) []string
	GetPolicyManager(cid string) policies.Manager
	InitChain(cid string)
	Initialize(init func(string), ccp ccprovider.ChaincodeProvider, sccp sysccprovider.SystemChaincodeProvider, pm txvalidator.PluginMapper, pr *platforms.Registry, deployedCCInfoProvider ledger.DeployedChaincodeInfoProvider, membershipProvider ledger.MembershipInfoProvider, metricsProvider metrics.Provider)
}

Operations exposes an interface to the package level functions that operated on singletons in the package. This is a step towards moving from package level data for the peer to instance level data.

var Default Operations = &peerImpl{
	createChainFromBlock: CreateChainFromBlock,
	getChannelConfig:     GetChannelConfig,
	getChannelsInfo:      GetChannelsInfo,
	getCurrConfigBlock:   GetCurrConfigBlock,
	getLedger:            GetLedger,
	getMSPIDs:            GetMSPIDs,
	getPolicyManager:     GetPolicyManager,
	initChain:            InitChain,
	initialize:           Initialize,
}

Default provides in implementation of the Peer interface that provides access to the package level state.

type PolicyCheckerProvider

type PolicyCheckerProvider func(resourceName string) deliver.PolicyCheckerFunc

PolicyCheckerProvider provides the corresponding policy checker for a given resource name

type Support

type Support interface {
	// GetApplicationConfig returns the configtxapplication.SharedConfig for the channel
	// and whether the Application config exists
	GetApplicationConfig(cid string) (channelconfig.Application, bool)
}

Support gives access to peer resources and avoids calls to static methods

var DefaultSupport Support = &supportImpl{operations: Default}

type SupportFactory

type SupportFactory interface {
	// NewSupport returns a Support interface
	NewSupport() Support
}

SupportFactory is a factory of Support interfaces
