Functions

func ExportAppendChain

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

func ExportChain

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

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 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从set命令行标志创建链管理器。 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 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检索当前请求的数据目录,如果未指定/(或空字符串),则终止/。如果节点正在启动一个testnet,那么将使用指定的datadir的/子目录。 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在设置本地标志时从本地标记中设置全局标志。/这是一个临时函数,用于将旧命令/标志迁移到/New格式。 /例如geth Account new-keystore/tmp/mykeystore-在调用此方法后等效于:/geth-keStore/tmp/mykeystore-Lightkdf帐户新 /,这允许使用现有的配置功能。迁移后,可以删除此函数,并且必须更改现有/配置功能,即使用本地标志 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
