README

This package contains the logic to access the relational database.

Currently, it is at the first version which is a little rough.

Historical reasoning for the current design:

  1. Geth is implemented on top of levelDB, and so makes heavy use of the k/v mechanism.
  2. Ten uses EdglessDb in production, and sqlite in testing.
  3. Ten started out by implementing the k/v primitives on top of sql.
  4. Then we decided to use the SQL features to simplify some business logic, which required exposing the sql primitives.
  5. Eventually, we ended up using SQL for everything, except the evm functionality.

The current abstractions are reflecting the first 4 steps.

Note: This package also mixes the EnclaveDB and TransactionDB implementations

SQL implementation

The implementation to read/write data to the db is also quite crude.

It mixes the SQL logic with the implementations for the EnclaveDB and DBTransaction. The reason it has to do that is because they depend on the SQL k/v logic.

func ReadCurrentHeadBatch(db *sql.DB) (*core.Batch, error)

todo - is there a better way to write this query?

func ReadCurrentSequencerNo 

func ReadCurrentSequencerNo(db *sql.DB) (*big.Int, error)

ReadReceiptsByBatchHash retrieves all the transaction receipts belonging to a block, including its corresponding metadata fields. If it is unable to populate these metadata fields then nil is returned.

The current implementation populates these metadata fields by reading the receipts' corresponding block body, so if the block body is not found it will return nil even if the receipt itself is stored.

func WriteRollup(dbtx DBTransaction, rollup *common.RollupHeader, internalHeader *common.CalldataRollupHeader) error

Types

type DBTransaction 

type DBTransaction interface {
	ethdb.Batch
	GetDB() *sql.DB
	ExecuteSQL(query string, args ...any)
}

DBTransaction - represents a database transaction implemented unusually. Typically, databases have a "beginTransaction" command which is also exposed by the db drivers, and then the applications just sends commands on that connection. There are rules as to what data is returned when running selects. This implementation works by collecting all statements, and then writing them and committing in one go todo - does it need to be an ethdb.Batch? todo - can we use the typical

type EnclaveDB 

type EnclaveDB interface {
	ethdb.Database
	GetSQLDB() *sql.DB
	NewDBTransaction() *dbTransaction
	BeginTx() (*sql.Tx, error)
}

EnclaveDB - An abstraction that implements the `ethdb.Database` on top of SQL, and also exposes underling sql primitives. Note: This might not be the best approach. Todo - consider a few design alternatives: The EnclaveDB - can be a factory that returns an Sql implementation of the ethdb.Database

func NewEnclaveDB 

func NewEnclaveDB(db *sql.DB, logger gethlog.Logger) (EnclaveDB, error)
