Functions

func DSN 

func DSN(ds config.Datasource) string

DSN renders a go-sql-driver/mysql DSN with tls, charset, sql_mode, timeout.

Types

type Pool 

type Pool struct {
	DB *sql.DB
	// contains filtered or unexported fields
}

Pool wraps a *sql.DB for the active datasource.

func Open 

func Open(ctx context.Context, ds config.Datasource) (*Pool, error)

Open opens a pooled connection and verifies it with a Ping. When SSH is enabled, a tunnel is established first and the DSN points at the local forwarded port.

func (*Pool) Close 

func (p *Pool) Close() error

Close releases the pool. If a backing SSH tunnel was established, it is torn down before the *sql.DB is closed.

func (*Pool) Ping 

func (p *Pool) Ping(ctx context.Context) error

Ping verifies the connection is alive.
