Types

type Application

type Application struct {
	*kvstore.Application

	PreviousCommittedState kvstore.State
	// contains filtered or unexported fields
}

Application is an ABCI application for use by end-to-end tests. It is a simple key/value store for strings, storing data in memory and persisting to disk as JSON, taking state sync snapshots if requested.

func NewApplication

func NewApplication(cfg kvstore.Config, opts ...kvstore.OptFunc) (*Application, error)

NewApplication creates the application.

func (*Application) ExtendVote

func (app *Application) ExtendVote(_ context.Context, req *abci.RequestExtendVote) (*abci.ResponseExtendVote, error)

ExtendVote will produce vote extensions in the form of random numbers to demonstrate vote extension nondeterminism.

In the next block, if there are any vote extensions from the previous block, a new transaction will be proposed that updates a special value in the key/value store ("extensionSum") with the sum of all of the numbers collected from the vote extensions.

func (*Application) FinalizeBlock

func (app *Application) FinalizeBlock(ctx context.Context, req *abci.RequestFinalizeBlock) (*abci.ResponseFinalizeBlock, error)

func (*Application) Rollback

func (app *Application) Rollback() error

func (*Application) VerifyVoteExtension

func (app *Application) VerifyVoteExtension(_ context.Context, req *abci.RequestVerifyVoteExtension) (*abci.ResponseVerifyVoteExtension, error)

VerifyVoteExtension simply validates vote extensions from other validators without doing anything about them. In this case, it just makes sure that the vote extension is a well-formed integer value.
