示例1: TstCreateCreditsOnStore

// TstCreateCreditsOnStore inserts a new credit in the given store for
// every item in the amounts slice.
func TstCreateCreditsOnStore(t *testing.T, s *wtxmgr.Store, pkScript []byte,
	amounts []int64) []wtxmgr.Credit {
	msgTx := createMsgTx(pkScript, amounts)
	meta := &wtxmgr.BlockMeta{
		Block: wtxmgr.Block{Height: TstInputsBlock},
	}

	rec, err := wtxmgr.NewTxRecordFromMsgTx(msgTx, time.Now())
	if err != nil {
		t.Fatal(err)
	}

	if err := s.InsertTx(rec, meta); err != nil {
		t.Fatal("Failed to create inputs: ", err)
	}

	credits := make([]wtxmgr.Credit, len(msgTx.TxOut))
	for i := range msgTx.TxOut {
		if err := s.AddCredit(rec, meta, uint32(i), false); err != nil {
			t.Fatal("Failed to create inputs: ", err)
		}
		credits[i] = wtxmgr.Credit{
			OutPoint: wire.OutPoint{
				Hash:  rec.Hash,
				Index: uint32(i),
			},
			BlockMeta: *meta,
			Amount:    btcutil.Amount(msgTx.TxOut[i].Value),
			PkScript:  msgTx.TxOut[i].PkScript,
		}
	}

示例2: addSelfToStore

func (tx *changeAwareTx) addSelfToStore(store *wtxmgr.Store) error {
	rec, err := wtxmgr.NewTxRecordFromMsgTx(tx.MsgTx, time.Now())
	if err != nil {
		return newError(ErrWithdrawalTxStorage, "error constructing TxRecord for storing", err)
	}

示例3: SignTx

// SignTx signs every input of the given MsgTx by looking up (on the addr
// manager) the redeem script for each of them and constructing the signature
// script using that and the given raw signatures.
// This function must be called with the manager unlocked.
func SignTx(msgtx *wire.MsgTx, sigs TxSigs, mgr *waddrmgr.Manager, store *wtxmgr.Store) error {
	// We use time.Now() here as we're not going to store the new TxRecord
	// anywhere -- we just need it to pass to store.PreviousPkScripts().
	rec, err := wtxmgr.NewTxRecordFromMsgTx(msgtx, time.Now())
	if err != nil {
		return newError(ErrTxSigning, "failed to construct TxRecord for signing", err)
	}
	pkScripts, err := store.PreviousPkScripts(rec, nil)
	if err != nil {
		return newError(ErrTxSigning, "failed to obtain pkScripts for signing", err)
	}
	for i, pkScript := range pkScripts {
		if err = signMultiSigUTXO(mgr, msgtx, i, pkScript, sigs[i]); err != nil {
			return err
		}
	}
	return nil

示例4: getEligibleInputs

// getEligibleInputs returns eligible inputs with addresses between startAddress
// and the last used address of lastSeriesID. They're reverse ordered based on
// their address.
func (p *Pool) getEligibleInputs(store *wtxmgr.Store, startAddress WithdrawalAddress,
	lastSeriesID uint32, dustThreshold btcutil.Amount, chainHeight int32,
	minConf int) ([]credit, error) {

	if p.Series(lastSeriesID) == nil {
		str := fmt.Sprintf("lastSeriesID (%d) does not exist", lastSeriesID)
		return nil, newError(ErrSeriesNotExists, str, nil)
	}
	unspents, err := store.UnspentOutputs()
	if err != nil {
		return nil, newError(ErrInputSelection, "failed to get unspent outputs", err)
	}
	addrMap, err := groupCreditsByAddr(unspents, p.manager.ChainParams())
	if err != nil {
		return nil, err
	}
	var inputs []credit
	address := startAddress
	for {
		log.Debugf("Looking for eligible inputs at address %v", address.addrIdentifier())

			var eligibles []credit
			for _, c := range candidates {
				candidate := newCredit(c, address)
				if p.isCreditEligible(candidate, minConf, chainHeight, dustThreshold) {
					eligibles = append(eligibles, candidate)

			inputs = append(inputs, eligibles...)
		}
		nAddr, err := nextAddr(p, address.seriesID, address.branch, address.index, lastSeriesID+1)
