type ErrPvtdataNotAvailable ¶

type ErrPvtdataNotAvailable struct {
    Msg string
}

func (*ErrPvtdataNotAvailable) Error ¶

func (e *ErrPvtdataNotAvailable) Error() string

type ErrUnsupportedTransaction ¶

ErrUnsupportedTransaction is expected to be thrown if a unsupported query is performed in an update transaction

type ErrUnsupportedTransaction struct {
    Msg string
}

func (*ErrUnsupportedTransaction) Error ¶

func (e *ErrUnsupportedTransaction) Error() string

type TxMgr ¶

TxMgr - an interface that a transaction manager should implement

type TxMgr interface {
    NewQueryExecutor(txid string) (ledger.QueryExecutor, error)
    NewTxSimulator(txid string) (ledger.TxSimulator, error)
    ValidateAndPrepare(blockAndPvtdata *ledger.BlockAndPvtData, doMVCCValidation bool) ([]*TxStatInfo, []byte, error)
    RemoveStaleAndCommitPvtDataOfOldBlocks(blocksPvtData map[uint64][]*ledger.TxPvtData) error
    GetLastSavepoint() (*version.Height, error)
    ShouldRecover(lastAvailableBlock uint64) (bool, uint64, error)
    CommitLostBlock(blockAndPvtdata *ledger.BlockAndPvtData) error
    Commit() error
    Rollback()
    Shutdown()
    Name() string
}

type TxStatInfo ¶

TxStatInfo encapsulates information about a transaction

type TxStatInfo struct {
    ValidationCode peer.TxValidationCode
    TxType         common.HeaderType
    ChaincodeID    *peer.ChaincodeID
    NumCollections int
}
