Types ¶

type Config ¶

type Config struct {
	// Stderr of the VM process written to this writer.
	Stderr io.Writer
	// Stdout of the VM process written to this writer.
	Stdout io.Writer
	// Duration engine server will wait for handshake success.
	HandshakeTimeout time.Duration
	Log              log.Logger
}

Config contains subprocess configuration.

type Status ¶

type Status struct {
	// Id of the process.
	Pid int
	// Address of the VM service.
	Addr string
}

Status contains subprocess status after successful bootstrap.

func Bootstrap ¶

func Bootstrap(
	ctx context.Context,
	listener net.Listener,
	cmd *exec.Cmd,
	config *Config,
) (*Status, runtime.Stopper, error)

Bootstrap starts a VM as a subprocess after initialization completes and pipes the IO to the appropriate writers. Handshake is the ZAP binary framed exchange ([len][protocol version][vm addr]).

The subprocess is expected to be stopped by the caller if a non-nil error is returned. If piping the IO fails then the subprocess will be stopped.
