Functions

func CheckExclusive

func CheckExclusive(ctx *cli.Context, args ...interface{})

CheckExclusive verifies that only a single instance of the provided flags was set by the user. Each flag might optionally be followed by a string type to specialize it further.

func ExportAppendChain

func ExportAppendChain(blockchain *core.BlockChain, fn string, first uint64, last uint64) error

ExportAppendChain exports a blockchain into the specified file, appending to the file if data already exists in it.

func ExportChain

func ExportChain(blockchain *core.BlockChain, fn string) error

ExportChain exports a blockchain into the specified file, truncating any data already present in the file.

func ExportPreimages

func ExportPreimages(db ethdb.Database, fn string) error

ExportPreimages exports all known hash preimages into the specified file, truncating any data already present in the file.

func Fatalf

func Fatalf(format string, args ...interface{})

Fatalf formats a message to standard error and exits the program. The message is also printed to standard output if standard error is redirected to a different file.

func GlobalBig

func GlobalBig(ctx *cli.Context, name string) *big.Int

GlobalBig returns the value of a BigFlag from the global flag set.

func ImportChain

func ImportChain(chain *core.BlockChain, fn string) error

func ImportPreimages

func ImportPreimages(db ethdb.Database, fn string) error

ImportPreimages imports a batch of exported hash preimages into the database.

func MakeAddress

func MakeAddress(ks *keystore.KeyStore, account string) (accounts.Account, error)

MakeAddress converts an account specified directly as a hex encoded string or a key index in the key store to an internal account representation.

func MakeChain

func MakeChain(ctx *cli.Context, stack *node.Node) (chain *core.BlockChain, chainDb ethdb.Database)

MakeChain creates a chain manager from set command line flags.

func MakeChainDatabase

func MakeChainDatabase(ctx *cli.Context, stack *node.Node) ethdb.Database

MakeChainDatabase open an LevelDB using the flags passed to the client and will hard crash if it fails.

func MakeChainForPBFT

func MakeChainForPBFT(ctx *cli.Context, stack *node.Node, cfg *eth2.Config, nodeCfg *node.Config) (chain *core.BlockChain, chainDb ethdb.Database)

MakeChain creates a chain manager from set command line flags.

func MakeConsolePreloads

func MakeConsolePreloads(ctx *cli.Context) []string

MakeConsolePreloads retrieves the absolute paths for the console JavaScript scripts to preload before starting.

func MakeDataDir

func MakeDataDir(ctx *cli.Context) string

MakeDataDir retrieves the currently requested data directory, terminating if none (or the empty string) is specified. If the node is starting a testnet, the a subdirectory of the specified datadir will be used.

func MakeGenesis

func MakeGenesis(ctx *cli.Context) *core.Genesis

func MakePasswordList

func MakePasswordList(ctx *cli.Context) []string

MakePasswordList reads password lines from the file specified by the global --password flag.

func MigrateFlags

func MigrateFlags(action func(ctx *cli.Context) error) func(*cli.Context) error

MigrateFlags sets the global flag from a local flag when it's set. This is a temporary function used for migrating old command/flags to the new format.

e.g. phoenixchain account new --keystore /tmp/mykeystore --lightkdf

is equivalent after calling this method with:

phoenixchain --keystore /tmp/mykeystore --lightkdf account new

This allows the use of the existing configuration functionality. When all flags are migrated this function can be removed and the existing configuration functionality must be changed that is uses local flags

func NewApp

func NewApp(gitCommit, gitDate, usage string) *cli.App

NewApp creates an app with sane defaults.

func RegisterEthService

func RegisterEthService(stack *node.Node, cfg *eth2.Config)

RegisterEthService adds an Ethereum client to the stack.

func RegisterEthStatsService

func RegisterEthStatsService(stack *node.Node, url string)

RegisterEthStatsService configures the Ethereum Stats daemon and adds it to the given node.

func SetEthConfig

func SetEthConfig(ctx *cli.Context, stack *node.Node, cfg *eth2.Config)

SetEthConfig applies eth-related command line flags to the config.

func SetNodeConfig

func SetNodeConfig(ctx *cli.Context, cfg *node.Config)

SetNodeConfig applies node-related command line flags to the config.

func SetP2PConfig

func SetP2PConfig(ctx *cli.Context, cfg *p2p.Config)

func SetPbft

func SetPbft(ctx *cli.Context, cfg *types.OptionsConfig, nodeCfg *node.Config)

func SplitTagsFlag

func SplitTagsFlag(tagsFlag string) map[string]string

func StartNode

func StartNode(stack *node.Node)
