var DefaultABCIQueryOptions = ABCIQueryOptions{Height: 0, Trusted: false}

DefaultABCIQueryOptions are latest height (0) and trusted equal to false (which will result in a proof being returned).

Functions

func DefaultWaitStrategy

func DefaultWaitStrategy(delta int64) (abort error)

DefaultWaitStrategy is the standard backoff algorithm, but you can plug in another one

func WaitForHeight

func WaitForHeight(c StatusClient, h int64, waiter Waiter) error

Wait for height will poll status at reasonable intervals until the block at the given height is available.

If waiter is nil, we use DefaultWaitStrategy, but you can also provide your own implementation

func WaitForOneEvent

func WaitForOneEvent(c EventsClient, evtTyp string, timeout time.Duration) (types.TMEventData, error)

WaitForOneEvent subscribes to a websocket event for the given event time and returns upon receiving it one time, or when the timeout duration has expired.

This handles subscribing and unsubscribing under the hood

Types

type ABCIClient

type ABCIClient interface {
	// Reading from abci app
	ABCIInfo() (*ctypes.ResultABCIInfo, error)
	ABCIQuery(path string, data cmn.HexBytes) (*ctypes.ResultABCIQuery, error)
	ABCIQueryWithOptions(path string, data cmn.HexBytes,
		opts ABCIQueryOptions) (*ctypes.ResultABCIQuery, error)

	// Writing to abci app
	BroadcastTxCommit(tx types.Tx) (*ctypes.ResultBroadcastTxCommit, error)
	BroadcastTxAsync(tx types.Tx) (*ctypes.ResultBroadcastTx, error)
	BroadcastTxSync(tx types.Tx) (*ctypes.ResultBroadcastTx, error)
}

ABCIClient groups together the functionality that principally affects the ABCI app. In many cases this will be all we want, so we can accept an interface which is easier to mock

type ABCIQueryOptions added in v0.12.0

type ABCIQueryOptions struct {
	Height  int64
	Trusted bool
}

ABCIQueryOptions can be used to provide options for ABCIQuery call other than the DefaultABCIQueryOptions.

type Client

Client wraps most important rpc calls a client would make if you want to listen for events, test if it also implements events.EventSwitch

type EventsClient added in v0.13.0

type EventsClient interface {
	types.EventBusSubscriber
}

EventsClient is reactive, you can subscribe to any message, given the proper string. see tendermint/types/events.go

type HTTP

type HTTP struct {
	*WSEvents
	// contains filtered or unexported fields
}

HTTP is a Client implementation that communicates with a tendermint node over json rpc and websockets.

This is the main implementation you probably want to use in production code. There are other implementations when calling the tendermint node in-process (local), or when you want to mock out the server for test code (mock).

type HistoryClient interface {
	Genesis() (*ctypes.ResultGenesis, error)
	BlockchainInfo(minHeight, maxHeight int64) (*ctypes.ResultBlockchainInfo, error)
}

HistoryClient shows us data from genesis to now in large chunks.

type Local

type Local struct {
	*types.EventBus
}

Local is a Client implementation that directly executes the rpc functions on a given node, without going through HTTP or GRPC.

This implementation is useful for:

* Running tests against a node in-process without the overhead of going through an http server * Communication between an ABCI app and Tendermint core when they are compiled in process.

For real clients, you probably want to use client.HTTP. For more powerful control during testing, you probably want the "client/mock" package.

func NewLocal

func NewLocal(node *nm.Node) *Local

NewLocal configures a client that calls the Node directly.

Note that given how rpc/core works with package singletons, that you can only have one node per process. So make sure test cases don't run in parallel, or try to simulate an entire network in one process...
