Overview ¶

Package watchdog keeps a hardware (or software) watchdog timer fed (GAPI-DIV-027): if the supervisor hangs, the kicks stop and the device resets the machine. A deliberate stop performs the magic close ('V') so the device disarms instead of firing.

Types ¶

type Watchdog ¶

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

Watchdog is one open keepalive device.

func Open ¶

func Open(device string, interval time.Duration) (*Watchdog, error)

Open opens the watchdog device (injectable path; /dev/watchdog on hardware). The kick interval must be well below the device timeout.

func (*Watchdog) Close ¶

func (w *Watchdog) Close() error

Close disarms the device (magic close) and releases it.

func (*Watchdog) Kick ¶

func (w *Watchdog) Kick() error

Kick resets the device timer.

func (*Watchdog) Run ¶

func (w *Watchdog) Run(ctx context.Context)

Run kicks on the interval until ctx ends, then magic-closes. The supervisor health loop owns ctx: a hung supervisor stops kicking, which is the point.
