type PrivateDataConfig 

type PrivateDataConfig struct {
	// PrivateDataConfig is used to configure a private data storage provider
	*ledger.PrivateDataConfig
	// StorePath is the filesystem path for private data storage.
	// It is internally computed by the ledger component,
	// so it is not in ledger.PrivateDataConfig and not exposed to other components.
	StorePath string
}

PrivateDataConfig encapsulates the configuration for private data storage on the ledger

type Provider 

type Provider struct {
	// contains filtered or unexported fields
}

Provider provides handle to specific 'Store' that in turn manages private write sets for a ledger

func NewProvider 

func NewProvider(conf *PrivateDataConfig) (*Provider, error)

NewProvider instantiates a StoreProvider

func (*Provider) Close 

func (p *Provider) Close()

Close closes the store

func (*Provider) Drop 

func (p *Provider) Drop(ledgerid string) error

Drop drops channel-specific data from the pvtdata store

func (*Provider) OpenStore 

func (p *Provider) OpenStore(ledgerid string) (*Store, error)

func (*Provider) SnapshotDataImporterFor 

func (p *Provider) SnapshotDataImporterFor(
	ledgerID string,
	lastBlockInSnapshot uint64,
	membershipProvider ledger.MembershipInfoProvider,
	configHistoryRetriever *confighistory.Retriever,
	tempDirRoot string,
) (*SnapshotDataImporter, error)

SnapshotDataImporterFor returns an implementation of interface privacyenabledstate.SnapshotPvtdataHashesConsumer The returned struct is expected to be registered for receiving the pvtdata hashes from snapshot and loads the data into pvtdata store.

type SnapshotDataImporter 

type SnapshotDataImporter struct {
	// contains filtered or unexported fields
}

func (*SnapshotDataImporter) ConsumeSnapshotData 

func (i *SnapshotDataImporter) ConsumeSnapshotData(
	namespace, collection string,
	keyHash, valueHash []byte,
	version *version.Height,
) error

func (*SnapshotDataImporter) Done 

func (i *SnapshotDataImporter) Done() error

type Store 

type Store struct {
	// contains filtered or unexported fields
}

Store manages the permanent storage of private write sets for a ledger

func (*Store) Commit 

func (s *Store) Commit(blockNum uint64, pvtData []*ledger.TxPvtData, missingPvtData ledger.TxMissingPvtData) error

Commit commits the pvt data as well as both the eligible and ineligible missing private data --- `eligible` denotes that the missing private data belongs to a collection for which this peer is a member; `ineligible` denotes that the missing private data belong to a collection for which this peer is not a member.

func (*Store) CommitPvtDataOfOldBlocks 

func (s *Store) CommitPvtDataOfOldBlocks(
	blocksPvtData map[uint64][]*ledger.TxPvtData,
	unreconciledMissingData ledger.MissingPvtDataInfo,
) error

CommitPvtDataOfOldBlocks commits the pvtData (i.e., previously missing data) of old blockp. The parameter `blocksPvtData` refers a list of old block's pvtdata which are missing in the pvtstore. Given a list of old block's pvtData, `CommitPvtDataOfOldBlocks` performs the following three operations (1) construct update entries (i.e., dataEntries, expiryEntries, missingDataEntries) 

from the above created data entries

(2) create a db update batch from the update entries (3) commit the update batch to the pvtStore

func (*Store) FetchBootKVHashes 

func (s *Store) FetchBootKVHashes(blkNum, txNum uint64, ns, coll string) (map[string][]byte, error)

FetchBootKVHashes returns the KVHashes from the data that was loaded from a snapshot at the time of bootstrapping. This funciton returns an error if the supplied blkNum is greater than the last block number in the booting snapshot

func (*Store) GetLastUpdatedOldBlocksPvtData 

func (s *Store) GetLastUpdatedOldBlocksPvtData() (map[uint64][]*ledger.TxPvtData, error)

GetLastUpdatedOldBlocksPvtData returns the pvtdata of blocks listed in `lastUpdatedOldBlocksList` TODO FAB-16293 -- GetLastUpdatedOldBlocksPvtData() can be removed either in v2.0 or in v2.1. If we decide to rebuild stateDB in v2.0, by default, the rebuild logic would take care of synching stateDB with pvtdataStore without calling GetLastUpdatedOldBlocksPvtData(). Hence, it can be safely removed. Suppose if we decide not to rebuild stateDB in v2.0, we can remove this function in v2.1.

func (*Store) GetMissingPvtDataInfoForMostRecentBlocks 

func (s *Store) GetMissingPvtDataInfoForMostRecentBlocks(maxBlock int) (ledger.MissingPvtDataInfo, error)

GetMissingPvtDataInfoForMostRecentBlocks returns the missing private data information for the most recent `maxBlock` blocks which miss at least a private data of a eligible collection.

func (*Store) GetPvtDataByBlockNum 

func (s *Store) GetPvtDataByBlockNum(blockNum uint64, filter ledger.PvtNsCollFilter) ([]*ledger.TxPvtData, error)

GetPvtDataByBlockNum returns only the pvt data corresponding to the given block number The pvt data is filtered by the list of 'ns/collections' supplied in the filter A nil filter does not filter any results

func (*Store) Init 

func (s *Store) Init(btlPolicy pvtdatapolicy.BTLPolicy)

Init initializes the store. This function is expected to be invoked before using the store

func (*Store) LastCommittedBlockHeight 

func (s *Store) LastCommittedBlockHeight() (uint64, error)

LastCommittedBlockHeight returns the height of the last committed block

func (*Store) ProcessCollsEligibilityEnabled 

func (s *Store) ProcessCollsEligibilityEnabled(committingBlk uint64, nsCollMap map[string][]string) error

ProcessCollsEligibilityEnabled notifies the store when the peer becomes eligible to receive data for an existing collection. Parameter 'committingBlk' refers to the block number that contains the corresponding collection upgrade transaction and the parameter 'nsCollMap' contains the collections for which the peer is now eligible to receive pvt data

func (*Store) ResetLastUpdatedOldBlocksList 

func (s *Store) ResetLastUpdatedOldBlocksList() error

ResetLastUpdatedOldBlocksList removes the `lastUpdatedOldBlocksList` entry from the store
