Functions

func TeardownDB

func TeardownDB(t testing.TB, db *Store)

TeardownDB cleans up a test DB instance.

func TempDir

func TempDir() string

TempDir returns a directory path for temporary test storage.

Types

type Store

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

Store defines an implementation of the Prysm Database interface using BoltDB as the underlying persistent kv-store for eth2.

func NewKVStore

func NewKVStore(dirPath string, pubKeys [][48]byte) (*Store, error)

NewKVStore initializes a new boltDB key-value store at the directory path specified, creates the kv-buckets based on the schema, and stores an open connection db object as a property of the Store struct.

func SetupDB

func SetupDB(t testing.TB, pubkeys [][48]byte) *Store

SetupDB instantiates and returns a DB instance for the validator client.

func (*Store) AttestationHistory

func (db *Store) AttestationHistory(ctx context.Context, publicKey []byte) (*slashpb.AttestationHistory, error)

AttestationHistory accepts a validator public key and returns the corresponding attestation history. Returns nil if there is no attestation history for the validator.

func (*Store) ClearDB

func (db *Store) ClearDB() error

ClearDB removes any previously stored data at the configured data directory.

func (*Store) Close

func (db *Store) Close() error

Close closes the underlying boltdb database.

func (*Store) DatabasePath

func (db *Store) DatabasePath() string

DatabasePath at which this database writes files.

func (*Store) DeleteAttestationHistory

func (db *Store) DeleteAttestationHistory(ctx context.Context, pubkey []byte) error

DeleteAttestationHistory deletes the attestation history for the corresponding validator public key.

func (*Store) DeleteProposalHistory

func (db *Store) DeleteProposalHistory(ctx context.Context, pubkey []byte) error

DeleteProposalHistory deletes the proposal history for the corresponding validator public key.

func (*Store) ProposalHistoryForEpoch

func (db *Store) ProposalHistoryForEpoch(ctx context.Context, publicKey []byte, epoch uint64) (bitfield.Bitlist, error)

ProposalHistoryForEpoch accepts a validator public key and returns the corresponding proposal history. Returns nil if there is no proposal history for the validator.

func (*Store) SaveAttestationHistory

func (db *Store) SaveAttestationHistory(ctx context.Context, pubKey []byte, attestationHistory *slashpb.AttestationHistory) error

SaveAttestationHistory returns the attestation history for the requested validator public key.

func (*Store) SaveProposalHistoryForEpoch

func (db *Store) SaveProposalHistoryForEpoch(ctx context.Context, pubKey []byte, epoch uint64, slotBits bitfield.Bitlist) error

SaveProposalHistoryForEpoch returns the proposal history for the requested validator public key.

func (*Store) Size

func (db *Store) Size() (int64, error)

Size returns the db size in bytes.
