Functions

func DBConfigFromEnv 

func DBConfigFromEnv() (uri, user, password, dbName string)

func NewEphemeralSQLiteConnection 

func NewEphemeralSQLiteConnection(name string) gorm.Dialector

NewEphemeralSQLiteConnection creates a connection to an in-memory SQLite DB. NOTE: Use simple names such as a random hex identifier or the filepath.Base of a test's name. Certain symbols will break the cfg string and cause a file to be created on disk. 

mode: set to memory for in-memory database
cache: set to shared which is required for in-memory databases
_foreign_keys: enforce foreign_key relations

func NewMetricsSQLiteConnection added in v0.7.0 

func NewMetricsSQLiteConnection(path string) gorm.Dialector

NewMetricsSQLiteConnection opens a sqlite db at the given path similarly to NewSQLiteConnection but with weaker consistency guarantees since it's optimised for recording metrics.

func NewMySQLConnection 

func NewMySQLConnection(user, password, addr, dbName string) gorm.Dialector

NewMySQLConnection creates a connection to a MySQL database.

func NewSQLLogger 

func NewSQLLogger(l *zap.Logger, config LoggerConfig) logger.Interface

func NewSQLiteConnection 

func NewSQLiteConnection(path string) gorm.Dialector

NewSQLiteConnection opens a sqlite db at the given path. 

_busy_timeout: set to prevent concurrent transactions from failing and
  instead have them block
_foreign_keys: enforce foreign_key relations
_journal_mode: set to WAL instead of delete since it's usually the fastest.
  Only downside is that the db won't work on network drives. In that case this
  should be made configurable and set to TRUNCATE or any of the other options.
  For reference see https://github.com/mattn/go-sqlite3#connection-string.

	ProofHeight    uint64 `gorm:"index;default:0"`
	RevisionHeight uint64 `gorm:"index;default:0"`
