Types

type InProgressAttestationDB added in v0.0.58

type InProgressAttestationDB interface {
	// RetrieveLatestCachedNonce gets the latest nonce cached for a particular origin-destination pair
	// returns ErrNoNonceForDomain if no nonce exists.
	RetrieveLatestCachedNonce(ctx context.Context, originID, destinationID uint32) (nonce uint32, err error)
	// StoreNewInProgressAttestation stores a in-progress attestation only if it hasn't already been stored
	StoreNewInProgressAttestation(ctx context.Context, attestation types.Attestation) error
	// StoreNewGuardInProgressAttestation stores a in-progress attestation only if it hasn't already been stored
	StoreNewGuardInProgressAttestation(ctx context.Context, attestation types.Attestation) error

	UpdateNotarySignature(ctx context.Context, inProgressAttestation types.InProgressAttestation) error
	// UpdateNotarySubmittedToAttestationCollectorTime sets the time the attestation was sent to Attestation Collector by the Notary.
	UpdateNotarySubmittedToAttestationCollectorTime(ctx context.Context, inProgressAttestation types.InProgressAttestation) error
	// ReUpdateNotarySubmittedToAttestationCollectorTime sets the time the attestation was sent to Attestation Collector by the Notary when resubmitting.
	ReUpdateNotarySubmittedToAttestationCollectorTime(ctx context.Context, inProgressAttestation types.InProgressAttestation) error
	// MarkNotaryConfirmedOnAttestationCollector confirms that the notary posted the signed attestation on the Attestation Collector.
	MarkNotaryConfirmedOnAttestationCollector(ctx context.Context, inProgressAttestation types.InProgressAttestation) error
	// RetrieveInProgressAttestation retrieves an in-progress attestation by <origin, destination, nonce>.
	RetrieveInProgressAttestation(ctx context.Context, originID, destinationID, nonce uint32) (inProgressAttestation types.InProgressAttestation, err error)
	// RetrieveNewestInProgressAttestation retrieves the newest in-progress attestation.
	RetrieveNewestInProgressAttestation(ctx context.Context, originID, destinationID uint32) (inProgressAttestation types.InProgressAttestation, err error)
	// RetrieveNewestInProgressAttestationIfInState retrieves the newest in-progress attestation in the given state.
	RetrieveNewestInProgressAttestationIfInState(ctx context.Context, originID, destinationID uint32, state types.AttestationState) (_ types.InProgressAttestation, err error)
	// StoreExistingSignedInProgressAttestation stores a signed in-progress attestation only if it hasn't already been stored
	StoreExistingSignedInProgressAttestation(ctx context.Context, signedAttestation types.SignedAttestation) error
	// UpdateGuardSignature sets the guard signature of the in-progress Attestation.
	UpdateGuardSignature(ctx context.Context, inProgressAttestation types.InProgressAttestation) error
	// UpdateGuardSubmittedToAttestationCollectorTime sets the time the attestation was sent to Attestation Collector by the Guard.
	UpdateGuardSubmittedToAttestationCollectorTime(ctx context.Context, inProgressAttestation types.InProgressAttestation) error

	ReUpdateGuardSubmittedToAttestationCollectorTime(ctx context.Context, inProgressAttestation types.InProgressAttestation) error
	// UpdateSubmittedToDestinationTime sets the time the attestation was sent to the Destination.
	UpdateSubmittedToDestinationTime(ctx context.Context, inProgressAttestation types.InProgressAttestation) error
	// MarkConfirmedOnDestination confirms that we posted the signed attestation on the Destination.
	MarkConfirmedOnDestination(ctx context.Context, inProgressAttestation types.InProgressAttestation) error
}

InProgressAttestationDB stores in-progress attesations. nolint

type MessageDB

type MessageDB interface {
	// RetrieveLatestCommittedMessageNonce gets the latest nonce of a committed message
	// returns ErrNoNonceForDomain if no nonce exists
	RetrieveLatestCommittedMessageNonce(ctx context.Context, domainID uint32) (nonce uint32, err error)
	// StoreMessageLatestBlockEnd stores the latest block end
	StoreMessageLatestBlockEnd(ctx context.Context, domainID uint32, blockNumber uint32) error
	// GetMessageLatestBlockEnd gets the message latest block
	// returns ErrNoStoredBlockForChain when not present
	GetMessageLatestBlockEnd(ctx context.Context, domainID uint32) (height uint32, err error)
	// StoreCommittedMessage stores a raw committed message
	StoreCommittedMessage(ctx context.Context, domainID uint32, message types.CommittedMessage) error
	// StoreSignedAttestations stores a signed attestation
	StoreSignedAttestations(ctx context.Context, attestation types.SignedAttestation) error
	// RetrieveSignedAttestationByNonce retrieves a signed attestation by nonce
	RetrieveSignedAttestationByNonce(ctx context.Context, domainID, nonce uint32) (attestation types.SignedAttestation, err error)
}

MessageDB stores messages. nolint TODO (joe): This needs to be refactored after we do the GlobalRegistry stuff

type MonitorDB

type MonitorDB interface {
	// StoreDispatchMessage stores a dispatch message
	StoreDispatchMessage(ctx context.Context, message types.Message) error
	// StoreAcceptedAttestation stores an accepted attestation
	StoreAcceptedAttestation(ctx context.Context, attestation types.Attestation) error
	// GetDelinquentMessage gets messages that were sent, but never received
	GetDelinquentMessages(ctx context.Context, destinationDomain uint32) ([]types.Message, error)
}

MonitorDB stores event data for monitoring.

type SynapseDB

type SynapseDB interface {
	MessageDB
	TxQueueDB
	MonitorDB
	InProgressAttestationDB
}

SynapseDB combines db types.

type TxQueueDB

type TxQueueDB interface {
	// StoreRawTx stores a raw transaction
	StoreRawTx(ctx context.Context, tx *ethTypes.Transaction, chainID *big.Int, from common.Address) error
	// StoreProcessedTx stores a tx that has already been processed
	StoreProcessedTx(ctx context.Context, tx *ethTypes.Transaction) error
	// GetNonceForChainID gets the latest nonce for a sender
	GetNonceForChainID(ctx context.Context, fromAddress common.Address, chainID *big.Int) (nonce uint64, err error)
}

TxQueueDB contains an interface for storing transactions currently being processed.
