The possible update statuses returned from the update engine

These correspond to current operation values exposed over DBus and defined by `update_engine`: https://github.com/coreos/update_engine/blob/v0.4.3/src/update_engine/update_attempter.h#L34-L43

Types

type Client

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

func New

func New() (c *Client, err error)

func (*Client) AttemptUpdate

func (c *Client) AttemptUpdate() error

AttemptUpdate will trigger an update if available. This is an asynchronous call - it returns immediately.

func (*Client) Close

func (c *Client) Close() error

func (*Client) GetStatus

func (c *Client) GetStatus() (result Status, err error)

GetStatus gets the current status from update_engine

func (*Client) RebootNeededSignal

func (c *Client) RebootNeededSignal(rcvr chan Status, stop <-chan struct{})

func (*Client) ReceiveStatuses

func (c *Client) ReceiveStatuses(rcvr chan Status, stop <-chan struct{})

ReceiveStatuses receives signal messages from dbus and sends them as Statues on the rcvr channel, until the stop channel is closed. An attempt is made to get the initial status and send it on the rcvr channel before receiving starts.

type Status

type Status struct {
	LastCheckedTime  int64
	Progress         float64
	CurrentOperation string
	NewVersion       string
	NewSize          int64
}

func NewStatus

func NewStatus(body []interface{}) (s Status)

func (*Status) String

func (s *Status) String() string
