Types

type Provider

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

Provider is the MariaDB migration.Provider. MariaDB DDL statements cause an implicit commit, so unlike PostgreSQL, migrations here cannot be wrapped in a rollback-able transaction; the history table's dirty flag is what makes a crash mid-migration detectable instead.

func Open

func Open(ctx context.Context, dsn string) (*Provider, error)

Open connects to MariaDB and verifies the connection.

func (*Provider) Close

func (p *Provider) Close() error

Close releases the underlying connection pool.

func (*Provider) DB

func (p *Provider) DB() migration.DB

DB returns the migration.DB the engine should use.

func (*Provider) History

func (p *Provider) History() migration.HistoryStore

func (*Provider) Locker

func (p *Provider) Locker(migration.DB) migration.Locker

func (*Provider) Name

func (p *Provider) Name() string

func (*Provider) SupportsTransactionalDDL

func (p *Provider) SupportsTransactionalDDL() bool
