Constants

const CustomReactorNamePrefix = "CUSTOM_"

CustomReactorNamePrefix is a prefix for all custom reactors to prevent clashes with built-in reactors.

Functions

func DefaultDBProvider

func DefaultDBProvider(ctx *DBContext) (dbm.DB, error)

DefaultDBProvider returns a database using the DBBackend and DBDir specified in the ctx.Config.

func LoadStateFromDBOrGenesisDocProvider

func LoadStateFromDBOrGenesisDocProvider(stateDB dbm.DB, genesisDocProvider GenesisDocProvider) (sm.State, *types.GenesisDoc, error)

LoadStateFromDBOrGenesisDocProvider attempts to load the state from the database, or creates one using the given genesisDocProvider and persists the result to the database. On success this also returns the genesis doc loaded through the given provider.

Types

type DBContext

type DBContext struct {
	ID     string
	Config *cfg.Config
}

DBContext specifies config information for loading a new DB.

type DBProvider

type DBProvider func(*DBContext) (dbm.DB, error)

DBProvider takes a DBContext and returns an instantiated DB.

type GenesisDocProvider

type GenesisDocProvider func() (*types.GenesisDoc, error)

GenesisDocProvider returns a GenesisDoc. It allows the GenesisDoc to be pulled from sources other than the filesystem, for instance from a distributed key-value store cluster.

func DefaultGenesisDocProviderFunc

func DefaultGenesisDocProviderFunc(config *cfg.Config) GenesisDocProvider

DefaultGenesisDocProviderFunc returns a GenesisDocProvider that loads the GenesisDoc from the config.GenesisFile() on the filesystem.

type MetricsProvider

type MetricsProvider func(chainID string) (*cs.Metrics, *p2p.Metrics, *mempl.Metrics, *sm.Metrics)

MetricsProvider returns a consensus, p2p and mempool Metrics.

func DefaultMetricsProvider

func DefaultMetricsProvider(config *cfg.InstrumentationConfig) MetricsProvider

DefaultMetricsProvider returns Metrics build using Prometheus client library if Prometheus is enabled. Otherwise, it returns no-op Metrics.

type Node

type Node struct {
	cmn.BaseService
	// contains filtered or unexported fields
}

Node is the highest level interface to a full Tendermint node. It includes all configuration information and running services.

func DefaultNewNode

func DefaultNewNode(config *cfg.Config, logger log.Logger) (*Node, error)

DefaultNewNode returns a Tendermint node with default settings for the PrivValidator, ClientCreator, GenesisDoc, and DBProvider. It implements NodeProvider.

func NewNode

func NewNode(config *cfg.Config,
	privValidator types.PrivValidator,
	nodeKey *p2p.NodeKey,
	clientCreator proxy.ClientCreator,
	genesisDocProvider GenesisDocProvider,
	dbProvider DBProvider,
	metricsProvider MetricsProvider,
	logger log.Logger,
	options ...Option) (*Node, error)

NewNode returns a new, ready to go, Tendermint Node.

func (*Node) BlockStore

func (*Node) EventBus

func (n *Node) EventBus() *types.EventBus

EventBus returns the Node's EventBus.

func (*Node) EvidencePool

func (n *Node) EvidencePool() *evidence.EvidencePool

EvidencePool returns the Node's EvidencePool.

func (*Node) GenesisDoc

func (n *Node) GenesisDoc() *types.GenesisDoc

GenesisDoc returns the Node's GenesisDoc.

func (*Node) IsListening

func (n *Node) IsListening() bool

func (*Node) Listeners

func (n *Node) Listeners() []string

func (*Node) Mempool

func (n *Node) Mempool() mempl.Mempool

Mempool returns the Node's mempool.

func (*Node) MempoolReactor

func (n *Node) MempoolReactor() *mempl.Reactor

MempoolReactor returns the Node's mempool reactor.

func (*Node) NodeInfo

func (n *Node) NodeInfo() p2p.NodeInfo

NodeInfo returns the Node's Info from the Switch.

func (*Node) OnStart

func (n *Node) OnStart() error

OnStart starts the Node. It implements cmn.Service.

func (*Node) OnStop

func (n *Node) OnStop()

OnStop stops the Node. It implements cmn.Service.

func (*Node) PEXReactor

func (n *Node) PEXReactor() *pex.PEXReactor
