Functions

func InitKVStore

func InitKVStore(app *PersistentKVStoreApplication)

InitKVStore initializes the kvstore app with some data, which allows tests to pass and is fine as long as you don't make any tx that modify the validator state

func MakeValSetChangeTx

func MakeValSetChangeTx(pubkey pc.PublicKey, power int64) []byte

func RandVal

func RandVal(i int) types.ValidatorUpdate

RandVal creates one random validator, with a key derived from the input value

func RandVals

func RandVals(cnt int) []types.ValidatorUpdate

RandVals returns a list of cnt validators for initializing the application. Note that the keys are deterministically derived from the index in the array, while the power is random (Change this if not desired)

Types

type Application

type Application struct {
	types.BaseApplication

	RetainBlocks int64 // blocks to retain after commit (via ResponseCommit.RetainHeight)
	// contains filtered or unexported fields
}

func NewApplication

func NewApplication() *Application

func (*Application) CheckTx

func (app *Application) CheckTx(req types.RequestCheckTx) types.ResponseCheckTx

func (*Application) Commit

func (app *Application) Commit() types.ResponseCommit

func (*Application) DeliverTx

func (app *Application) DeliverTx(req types.RequestDeliverTx) types.ResponseDeliverTx

tx is either "key=value" or just arbitrary bytes

func (*Application) Info

func (app *Application) Info(req types.RequestInfo) (resInfo types.ResponseInfo)

func (*Application) Query

func (app *Application) Query(reqQuery types.RequestQuery) (resQuery types.ResponseQuery)

Returns an associated value or nil if missing.

type PersistentKVStoreApplication

type PersistentKVStoreApplication struct {

	// validator set
	ValUpdates []types.ValidatorUpdate
	// contains filtered or unexported fields
}

func NewPersistentKVStoreApplication

func NewPersistentKVStoreApplication(dbDir string) *PersistentKVStoreApplication

func (*PersistentKVStoreApplication) ApplySnapshotChunk

func (app *PersistentKVStoreApplication) ApplySnapshotChunk(
	req types.RequestApplySnapshotChunk) types.ResponseApplySnapshotChunk

func (*PersistentKVStoreApplication) BeginBlock

func (app *PersistentKVStoreApplication) BeginBlock(req types.RequestBeginBlock) types.ResponseBeginBlock

Track the block hash and header information

func (*PersistentKVStoreApplication) CheckTx

func (app *PersistentKVStoreApplication) CheckTx(req types.RequestCheckTx) types.ResponseCheckTx

func (*PersistentKVStoreApplication) Commit

func (app *PersistentKVStoreApplication) Commit() types.ResponseCommit

Commit will panic if InitChain was not called

func (*PersistentKVStoreApplication) DeliverTx

func (app *PersistentKVStoreApplication) DeliverTx(req types.RequestDeliverTx) types.ResponseDeliverTx

tx is either "val:pubkey!power" or "key=value" or just arbitrary bytes

func (*PersistentKVStoreApplication) EndBlock

func (app *PersistentKVStoreApplication) EndBlock(req types.RequestEndBlock) types.ResponseEndBlock

Update the validator set

func (*PersistentKVStoreApplication) Info

func (app *PersistentKVStoreApplication) Info(req types.RequestInfo) types.ResponseInfo

func (*PersistentKVStoreApplication) InitChain

func (app *PersistentKVStoreApplication) InitChain(req types.RequestInitChain) types.ResponseInitChain

func (*PersistentKVStoreApplication) Query

func (app *PersistentKVStoreApplication) Query(reqQuery types.RequestQuery) (resQuery types.ResponseQuery)

When path=/val and data={validator address}, returns the validator update (types.ValidatorUpdate) varint encoded. For any other path, returns an associated value or nil if missing.
