Functions

func GetBlockCmd

func GetBlockCmd(logger log.Logger, home string, args []string) error

GetBlockCmd extracts a block from a blockstore.db and outputs as json It takes the last block unless -height is explicitly specified It writes the json to stdout

func InitCmd

func InitCmd(gen GenOptions, logger log.Logger, home string, args []string) error

InitCmd will initialize all files for tendermint, along with proper app_options. The application can pass in a function to generate proper options. And may want to use GenerateCoinKey to create default account(s).

func RetryCmd

func RetryCmd(makeApp InlineAppGenerator, logger log.Logger, home string, args []string) error

RetryCmd takes the app state and the last block from the file system It verifies that they match, then rolls back one block and re-runs the given block It will output the new hash after running.

If -error is passed, then it will try -max times until a different app hash results

func StartCmd

func StartCmd(gen AppGenerator, logger log.Logger, home string, args []string) error

StartCmd initializes the application, and

Types

type AppGenerator

type AppGenerator func(string, log.Logger, bool) (abci.Application, error)

AppGenerator lets us lazily initialize app, using home dir and logger potentially initialized with other flags

type GenOptions

type GenOptions func(args []string) (json.RawMessage, error)

GenOptions can parse command-line and flag to generate default app_options for the genesis file. This is application-specific

type GenesisDoc

type GenesisDoc map[string]json.RawMessage

GenesisDoc involves some tendermint-specific structures we don't want to parse, so we just grab it into a raw object format, so we can add one line.

type InlineAppGenerator

type InlineAppGenerator func(weave.CommitKVStore, log.Logger, bool) abci.Application

InlineAppGenerator should be implemented by the app/init.go file
