Types

type ExecQuerier

type ExecQuerier interface {
	Exec(ctx context.Context, sql string, arguments ...interface{}) (commandTag pgconn.CommandTag, err error)
	Query(ctx context.Context, sql string, args ...interface{}) (pgx.Rows, error)
	QueryRow(ctx context.Context, sql string, args ...interface{}) pgx.Row
}

type PostgresStorage

type PostgresStorage struct {
	*pgxpool.Pool
	// contains filtered or unexported fields
}

PostgresStorage implements the Storage interface

func NewPostgresStorage

func NewPostgresStorage(cfg state.Config, db *pgxpool.Pool) *PostgresStorage

NewPostgresStorage creates a new StateDB

func (*PostgresStorage) AddGeneratedProof

func (p *PostgresStorage) AddGeneratedProof(ctx context.Context, proof *state.Proof, dbTx pgx.Tx) error

AddGeneratedProof adds a generated proof to the storage

func (*PostgresStorage) AddSequence

func (p *PostgresStorage) AddSequence(ctx context.Context, sequence state.Sequence, dbTx pgx.Tx) error

AddSequence stores the sequence information to allow the aggregator verify sequences.

func (*PostgresStorage) CheckProofContainsCompleteSequences

func (p *PostgresStorage) CheckProofContainsCompleteSequences(
	ctx context.Context, proof *state.Proof, dbTx pgx.Tx,
) (bool, error)

CheckProofContainsCompleteSequences checks if a recursive proof contains complete sequences

func (*PostgresStorage) CheckProofExistsForBatch

func (p *PostgresStorage) CheckProofExistsForBatch(ctx context.Context, batchNumber uint64, dbTx pgx.Tx) (bool, error)

CheckProofExistsForBatch checks if the batch is already included in any proof

func (*PostgresStorage) CleanupGeneratedProofs

func (p *PostgresStorage) CleanupGeneratedProofs(ctx context.Context, batchNumber uint64, dbTx pgx.Tx) error

CleanupGeneratedProofs deletes from the storage the generated proofs up to the specified batch number included.

func (*PostgresStorage) CleanupLockedProofs

func (p *PostgresStorage) CleanupLockedProofs(ctx context.Context, duration string, dbTx pgx.Tx) (int64, error)

CleanupLockedProofs deletes from the storage the proofs locked in generating state for more than the provided threshold.

func (*PostgresStorage) DeleteGeneratedProofs

func (p *PostgresStorage) DeleteGeneratedProofs(
	ctx context.Context, batchNumber uint64, batchNumberFinal uint64, dbTx pgx.Tx,
