Types

type ChainConfig 

type ChainConfig struct {
	ChainId    *big.Int          `json:"chainId"` // Chain id identifies the current chain and is used for replay protection
	Prometheus *PrometheusConfig `json:"prometheus"`
}

func (*ChainConfig) CheckCompatible 

func (c *ChainConfig) CheckCompatible(newcfg *ChainConfig, height uint64) *ConfigCompatError

CheckCompatible checks whether scheduled fork transitions have been imported with a mismatching chain configuration.

func (*ChainConfig) GasTable 

func (c *ChainConfig) GasTable(num *big.Int) GasTable

GasTable returns the gas table corresponding to the current phase (homestead or homestead reprice).

The returned GasTable's fields shouldn't, under any circumstances, be changed.

func (*ChainConfig) String 

func (c *ChainConfig) String() string

String implements the fmt.Stringer interface.

type ConfigCompatError 

type ConfigCompatError struct {
	What string
	// block numbers of the stored and new configurations
	StoredConfig, NewConfig *big.Int
	// the block number to which the local chain must be rewound to correct the error
	RewindTo uint64
}

ConfigCompatError is raised if the locally-stored blockchain is initialised with a ChainConfig that would alter the past.

func (*ConfigCompatError) Error 

func (err *ConfigCompatError) Error() string

	// request, including the body.

func (*Nodeconfig) IPCEndpoint 

func (c *Nodeconfig) IPCEndpoint() string

IPCEndpoint resolves an IPC endpoint based on a configured value, taking into account the set data folders as well as the designated platform we're currently running on.

func (*Nodeconfig) InstanceDir 

func (c *Nodeconfig) InstanceDir() string

func (*Nodeconfig) NodeDB 

func (c *Nodeconfig) NodeDB() string

NodeDB returns the path to the discovery node database.

func (*Nodeconfig) NodeKey 

func (c *Nodeconfig) NodeKey() error

NodeKey retrieves the currently configured private key of the node, checking first any manually set key, falling back to the one found in the configured data folder. If no key can be found, a new one is generated.

func (*Nodeconfig) NodeKeyTemp 

func (c *Nodeconfig) NodeKeyTemp() *ecdsa.PrivateKey

TODO: shanlin to del this function NodeKey retrieves the currently configured private key of the node, checking first any manually set key, falling back to the one found in the configured data folder. If no key can be found, a new one is generated.

func (*Nodeconfig) NodeName 

func (c *Nodeconfig) NodeName() string

NodeName returns the devp2p node identifier.

func (*Nodeconfig) ResolvePath 

func (c *Nodeconfig) ResolvePath(path string) string

resolvePath resolves path in the instance directory.

func (*Nodeconfig) StringName 

func (c *Nodeconfig) StringName() string

type PrometheusConfig
