Functions

func DefaultDBProvider 

func DefaultDBProvider(ctx *DBContext) (dbm.DB, error)

DefaultDBProvider returns a database using the DBBackend and DBDir specified in the ctx.Config.

func LoadStateFromDBOrGenesisDocProvider 

func LoadStateFromDBOrGenesisDocProvider(
	stateDB dbm.DB,
	genesisDocProvider GenesisDocProvider,
) (sm.State, *types.GenesisDoc, error)

LoadStateFromDBOrGenesisDocProvider attempts to load the state from the database, or creates one using the given genesisDocProvider and persists the result to the database. On success this also returns the genesis doc loaded through the given provider.

func ParseMisbehaviors 

func ParseMisbehaviors(str string) (map[int64]cs.Misbehavior, error)

ParseMisbehaviors is a util function that converts a comma separated string into a map of misbehaviors to be executed by the maverick node

Types

type DBContext 

type DBContext struct {
	ID     string
	Config *cfg.Config
}

DBContext specifies config information for loading a new DB.

type DBProvider 

type DBProvider func(*DBContext) (dbm.DB, error)

DBProvider takes a DBContext and returns an instantiated DB.

type FilePV 

type FilePV struct {
	Key           FilePVKey
	LastSignState FilePVLastSignState
}

FilePV implements PrivValidator using data persisted to disk to prevent double signing. NOTE: the directories containing pv.Key.filePath and pv.LastSignState.filePath must already exist. It includes the LastSignature and LastSignBytes so we don't lose the signature if the process crashes after signing but before the resulting consensus message is processed.

func GenFilePV 

func GenFilePV(keyFilePath, stateFilePath string) *FilePV

GenFilePV generates a new validator with randomly generated private key and sets the filePaths, but does not call Save().

func LoadFilePV 

func LoadFilePV(keyFilePath, stateFilePath string) *FilePV

LoadFilePV loads a FilePV from the filePaths. The FilePV handles double signing prevention by persisting data to the stateFilePath. If either file path does not exist, the program will exit.

func LoadFilePVEmptyState 

func LoadFilePVEmptyState(keyFilePath, stateFilePath string) *FilePV

LoadFilePVEmptyState loads a FilePV from the given keyFilePath, with an empty LastSignState. If the keyFilePath does not exist, the program will exit.

func LoadOrGenFilePV 

func LoadOrGenFilePV(keyFilePath, stateFilePath string) *FilePV

LoadOrGenFilePV loads a FilePV from the given filePaths or else generates a new one and saves it to the filePaths.

func (*FilePV) GetAddress 

func (pv *FilePV) GetAddress() types.Address

GetAddress returns the address of the validator. Implements PrivValidator.

func (*FilePV) GetPubKey 

func (pv *FilePV) GetPubKey() (crypto.PubKey, error)

GetPubKey returns the public key of the validator. Implements PrivValidator.

func (*FilePV) Reset 

func (pv *FilePV) Reset()

Reset resets all fields in the FilePV. NOTE: Unsafe!

func (*FilePV) Save 

func (pv *FilePV) Save()

Save persists the FilePV to disk.

func (*FilePV) SignProposal 

func (pv *FilePV) SignProposal(chainID string, proposal *tmproto.Proposal) error

SignProposal signs a canonical representation of the proposal, along with the chainID. Implements PrivValidator.

func (*FilePV) SignVote 

func (pv *FilePV) SignVote(chainID string, vote *tmproto.Vote) error

SignVote signs a canonical representation of the vote, along with the chainID. Implements PrivValidator.

func (*FilePV) String 

func (pv *FilePV) String() string

String returns a string representation of the FilePV.

type FilePVKey 

type FilePVKey struct {
	Address types.Address  `json:"address"`
	PubKey  crypto.PubKey  `json:"pub_key"`
	PrivKey crypto.PrivKey `json:"priv_key"`
	// contains filtered or unexported fields
}

FilePVKey stores the immutable part of PrivValidator.

func (FilePVKey) Save 

func (pvKey FilePVKey) Save()

Save persists the FilePVKey to its filePath.

type FilePVLastSignState 

type FilePVLastSignState struct {
	Height    int64            `json:"height"`
	Round     int32            `json:"round"`
	Step      int8             `json:"step"`
	Signature []byte           `json:"signature,omitempty"`
	SignBytes tmbytes.HexBytes `json:"signbytes,omitempty"`
	// contains filtered or unexported fields
}

FilePVLastSignState stores the mutable part of PrivValidator.

func (*FilePVLastSignState) CheckHRS 

func (lss *FilePVLastSignState) CheckHRS(height int64, round int32, step int8) (bool, error)

CheckHRS checks the given height, round, step (HRS) against that of the FilePVLastSignState. It returns an error if the arguments constitute a regression, or if they match but the SignBytes are empty. The returned boolean indicates whether the last Signature should be reused - it returns true if the HRS matches the arguments and the SignBytes are not empty (indicating we have already signed for this HRS, and can reuse the existing signature). It panics if the HRS matches the arguments, there's a SignBytes, but no Signature.

func (*FilePVLastSignState) Save 

func (lss *FilePVLastSignState) Save()

Save persists the FilePvLastSignState to its filePath.

type GenesisDocProvider 

type GenesisDocProvider func() (*types.GenesisDoc, error)

GenesisDocProvider returns a GenesisDoc. It allows the GenesisDoc to be pulled from sources other than the filesystem, for instance from a distributed key-value store cluster.

func DefaultGenesisDocProviderFunc 

func DefaultGenesisDocProviderFunc(config *cfg.Config) GenesisDocProvider

DefaultGenesisDocProviderFunc returns a GenesisDocProvider that loads the GenesisDoc from the config.GenesisFile() on the filesystem.
