Functions

func Create 

func Create(namespace walletdb.Namespace) error

Create creates a new persistent stake manager in the passed database namespace. A ManagerError with an error code of ErrAlreadyExists will be returned the address manager already exists in the specified namespace.

func DisableLog 

func DisableLog()

DisableLog disables all library log output. Logging output is disabled by default until either UseLogger or SetLogWriter are called.

func UseLogger 

func UseLogger(logger btclog.Logger)

UseLogger uses a specified Logger to output package logging info. This should be used in preference to SetLogWriter if the caller is also using btclog.

Types

type ErrorCode 

type ErrorCode int

ErrorCode identifies a kind of error. 

const (
	// ErrDatabase indicates a generic error with the underlying database.
	// When this error code is set, the Err field of the TxStoreError will
	// be set to the underlying error returned from the database.
	ErrDatabase ErrorCode = iota

	// ErrInput indicates there was a problem with the input given.
	ErrInput

	// ErrNoExist indicates that the specified database does not exist.
	ErrNoExist

	// ErrAlreadyExists indicates that the specified database already exists.
	ErrAlreadyExists

	// ErrSStxNotFound indicates that the requested tx hash is not known to
	// the SStx store.
	ErrSStxNotFound

	// ErrSSGensNotFound indicates that the requested tx hash is not known to
	// the SSGens store.
	ErrSSGensNotFound

	// ErrSSRtxsNotFound indicates that the requested tx hash is not known to
	// the SSRtxs store.
	ErrSSRtxsNotFound

	// ErrStoreClosed indicates that a function was called after the stake
	// store was closed.
	ErrStoreClosed
)

These constants are used to identify a specific StakeStoreError.

func (ErrorCode) String 

func (e ErrorCode) String() string

String returns the ErrorCode as a human-readable name.

type StakeNotification 

type StakeNotification struct {
	TxType    int8 // These are the same as in staketx.go of stake, but int8
	TxHash    chainhash.Hash
	BlockHash chainhash.Hash // SSGen only
	Height    int32          // SSGen only
	Amount    int64          // SStx only
	SStxIn    chainhash.Hash // SSGen and SSRtx
	VoteBits  uint16         // SSGen only
}

StakeNotification is the data structure that contains information about an SStx (ticket), SSGen (vote), or SSRtx (revocation) produced by wallet.

type StakeStore 

type StakeStore struct {
	Params  *chaincfg.Params
	Manager *waddrmgr.Manager

}

StakeStore represents a safely accessible database of stake transactions.

func Open 

func Open(namespace walletdb.Namespace, manager *waddrmgr.Manager,
	params *chaincfg.Params) (*StakeStore, error)

Open loads an existing stake manager from the given namespace, waddrmgr, and network parameters.

A ManagerError with an error code of ErrNoExist will be returned if the passed manager does not exist in the specified namespace.

func (*StakeStore) CheckHashInStore 

func (s *StakeStore) CheckHashInStore(hash *chainhash.Hash) bool

CheckHashInStore is the exported version of CheckHashInStore that is safe for concurrent access.

func (*StakeStore) Close 

func (s *StakeStore) Close() error

Close cleanly shuts down the stake store.

func (*StakeStore) DumpSSGenHashes 

func (s *StakeStore) DumpSSGenHashes() ([]chainhash.Hash, error)

DumpSSGenHashes is the exported version of dumpSSGenHashes that is safe for concurrent access.

func (*StakeStore) DumpSSRtxHashes 

func (s *StakeStore) DumpSSRtxHashes() ([]chainhash.Hash, error)

DumpSSRtxHashes is the exported version of dumpSSRtxHashes that is safe for concurrent access.

func (*StakeStore) DumpSSRtxTickets 

func (s *StakeStore) DumpSSRtxTickets() ([]chainhash.Hash, error)

DumpSSRtxTickets is the exported version of dumpSSRtxTickets that is safe for concurrent access.

func (*StakeStore) DumpSStxHashes 

func (s *StakeStore) DumpSStxHashes() ([]chainhash.Hash, error)

DumpSStxHashes is the exported version of dumpSStxHashes that is safe for concurrent access.

func (*StakeStore) DumpSStxHashesForAddress 

func (s *StakeStore) DumpSStxHashesForAddress(addr dcrutil.Address) ([]chainhash.Hash, error)

DumpSStxHashesForAddress is the exported version of dumpSStxHashesForAddress that is safe for concurrent access.

func (StakeStore) HandleMissedTicketsNtfn 

func (s StakeStore) HandleMissedTicketsNtfn(blockHash *chainhash.Hash,
	blockHeight int64,
	tickets []*chainhash.Hash) ([]*StakeNotification, error)

HandleMissedTicketsNtfn scans the list of missed tickets and, if any of these tickets in the sstx store match these tickets, spends them as SSRtx.

func (StakeStore) HandleWinningTicketsNtfn 

func (s StakeStore) HandleWinningTicketsNtfn(blockHash *chainhash.Hash,
	blockHeight int64,
	tickets []*chainhash.Hash,
	defaultVoteBits uint16) ([]*StakeNotification, error)

HandleWinningTicketsNtfn scans the list of eligible tickets and, if any of these tickets in the sstx store match these tickets, spends them as votes.

func (*StakeStore) InsertSSGen 

func (s *StakeStore) InsertSSGen(blockHash *chainhash.Hash, blockHeight int64,
	ssgenHash *chainhash.Hash, voteBits uint16, sstxHash *chainhash.Hash) error

func (*StakeStore) SendRawTransaction 

func (s *StakeStore) SendRawTransaction(msgTx *wire.MsgTx) (*chainhash.Hash,
	error)

SendRawTransaction sends a raw transaction using the chainSvr. TODO Shouldn't this be locked? Eventually import the mutex lock from wallet maybe.

func (*StakeStore) SetChainSvr 

func (s *StakeStore) SetChainSvr(chainSvr *walletchain.RPCClient)

SetChainSvr is used to set the chainSvr to a given pointer. Should be called after chainSvr is initialized in wallet.

func (*StakeStore) SignVRTransaction 

func (s *StakeStore) SignVRTransaction(msgTx *wire.MsgTx, sstx *dcrutil.Tx,
	isSSGen bool) error

SignVRTransaction signs a vote (SSGen) or revocation (SSRtx) transaction. isSSGen indicates if it is an SSGen; if it's not, it's an SSRtx.

func (*StakeStore) UpdateSStxVoteBits 

func (s *StakeStore) UpdateSStxVoteBits(sstx *chainhash.Hash,
	voteBits uint16) error

UpdateSStxVoteBits is the exported version of updateSStxVoteBits that is safe for concurrent access.

type StakeStoreError 

type StakeStoreError struct {
	ErrorCode   ErrorCode // Describes the kind of error
	Description string    // Human readable description of the issue
