Functions ¶
func ExportAppendChain ¶
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 ¶ added in v1.8.3
func ExportPreimages(db *ethdb.LDBDatabase, 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 ImportChain ¶
func ImportChain(chain *core.BlockChain, fn string) error
func ImportPreimages ¶ added in v1.8.3
func ImportPreimages(db *ethdb.LDBDatabase, fn string) error
ImportPreimages imports a batch of exported hash preimages into the database.
func MakeAddress ¶ added in v1.4.0
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 MakeChainDatabase ¶ added in v1.4.0
MakeChainDatabase open an LevelDB using the flags passed to the client and will hard crash if it fails.
func MakeConsolePreloads ¶ added in v1.4.14
func MakeConsolePreloads(ctx *cli.Context) []string
MakeConsolePreloads retrieves the absolute paths for the console JavaScript scripts to preload before starting.
func MakeDataDir ¶ added in v1.5.0
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 ¶ added in v1.6.0
func MakePasswordList ¶ added in v1.4.0
func MakePasswordList(ctx *cli.Context) []string
MakePasswordList reads password lines from the file specified by the global --password flag.
func MigrateFlags ¶ added in v1.6.1
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. geth account new --keystore /tmp/mykeystore --lightkdf
is equivalent after calling this method with:
geth --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, usage string) *cli.App
NewApp creates an app with sane defaults.
func RegisterDashboardService ¶ added in v1.7.3
RegisterDashboardService adds a dashboard to the stack.
func RegisterEthService ¶ added in v1.5.0
RegisterEthService adds an Ethereum client to the stack.

RegisterEthStatsService configures the Ethereum Stats daemon and adds it to th egiven node.
func RegisterShhService ¶ added in v1.5.0
RegisterShhService configures Whisper and adds it to the given node.
func SetDashboardConfig ¶ added in v1.7.3
SetDashboardConfig applies dashboard related command line flags to the config.
func SetEthConfig ¶ added in v1.6.0
SetEthConfig applies eth-related command line flags to the config.
func SetNodeConfig ¶ added in v1.6.0
SetNodeConfig applies node-related command line flags to the config.
func SetP2PConfig ¶ added in v1.6.0
func SetShhConfig ¶ added in v1.6.7
