Types

type BaseApp

type BaseApp struct {
	// contains filtered or unexported fields
}

BaseApp reflects the ABCI application implementation.

func NewBaseApp

func NewBaseApp(
	name string, logger log.Logger, db dbm.DB, txDecoder sdk.TxDecoder, options ...func(*BaseApp),
) *BaseApp

NewBaseApp returns a reference to an initialized BaseApp. It accepts a variadic number of option functions, which act on the BaseApp to set configuration choices.

NOTE: The db is used to store the version number for now.

func (*BaseApp) AppVersion

func (app *BaseApp) AppVersion() string

AppVersion returns the application's version string.

func (*BaseApp) BeginBlock

func (app *BaseApp) BeginBlock(req abci.RequestBeginBlock) (res abci.ResponseBeginBlock)

BeginBlock implements the ABCI application interface.

func (*BaseApp) Check

func (app *BaseApp) Check(tx sdk.Tx) (sdk.GasInfo, *sdk.Result, error)

func (*BaseApp) CheckTx

func (app *BaseApp) CheckTx(req abci.RequestCheckTx) abci.ResponseCheckTx

CheckTx implements the ABCI interface and executes a tx in CheckTx mode. In CheckTx mode, messages are not executed. This means messages are only validated and only the AnteHandler is executed. State is persisted to the BaseApp's internal CheckTx state if the AnteHandler passes. Otherwise, the ResponseCheckTx will contain releveant error information. Regardless of tx execution outcome, the ResponseCheckTx will contain relevant gas execution context.

func (*BaseApp) Commit

func (app *BaseApp) Commit() (res abci.ResponseCommit)

Commit implements the ABCI interface. It will commit all state that exists in the deliver state's multi-store and includes the resulting commit ID in the returned abci.ResponseCommit. Commit will set the check state based on the latest header and reset the deliver state. Also, if a non-zero halt height is defined in config, Commit will execute a deferred function call to check against that height and gracefully halt if it matches the latest committed height.

func (*BaseApp) Deliver

func (app *BaseApp) Deliver(tx sdk.Tx) (sdk.GasInfo, *sdk.Result, error)

func (*BaseApp) DeliverTx

func (app *BaseApp) DeliverTx(req abci.RequestDeliverTx) abci.ResponseDeliverTx

DeliverTx implements the ABCI interface and executes a tx in DeliverTx mode. State only gets persisted if all messages are valid and get executed successfully. Otherwise, the ResponseDeliverTx will contain releveant error information. Regardless of tx execution outcome, the ResponseDeliverTx will contain relevant gas execution context.

func (*BaseApp) EndBlock

func (app *BaseApp) EndBlock(req abci.RequestEndBlock) (res abci.ResponseEndBlock)

EndBlock implements the ABCI interface.

func (*BaseApp) FilterPeerByAddrPort

func (app *BaseApp) FilterPeerByAddrPort(info string) abci.ResponseQuery

FilterPeerByAddrPort filters peers by address/port.

func (*BaseApp) FilterPeerByID

type StoreLoader

type StoreLoader func(ms sdk.CommitMultiStore) error

StoreLoader defines a customizable function to control how we load the CommitMultiStore from disk. This is useful for state migration, when loading a datastore written with an older version of the software. In particular, if a module changed the substore key name (or removed a substore) between two versions of the software.

func StoreLoaderWithUpgrade

StoreLoaderWithUpgrade is used to prepare baseapp with a fixed StoreLoader pattern. This is useful in test cases, or with custom upgrade loading logic.

func UpgradeableStoreLoader

func UpgradeableStoreLoader(upgradeInfoPath string) StoreLoader

UpgradeableStoreLoader can be configured by SetStoreLoader() to check for the existence of a given upgrade file - json encoded StoreUpgrades data.

If not file is present, it will peform the default load (no upgrades to store).

If the file is present, it will parse the file and execute those upgrades (rename or delete stores), while loading the data. It will also delete the upgrade file upon successful load, so that the upgrade is only applied once, and not re-applied on next restart

This is useful for in place migrations when a store key is renamed between two versions of the software. (TODO: this code will move to x/upgrades when PR #4233 is merged, here mainly to help test the design)
