示例1: processMachine
// processMachine retrieves version and status information for the given machine.
// It also returns deprecated legacy status information.
func processMachine(machine *state.Machine) (out params.AgentStatus, compat params.AgentStatus) {
out.Life = processLife(machine)
if t, err := machine.AgentTools(); err == nil {
out.Version = t.Version.Number.String()
}
populateStatusFromGetter(&out, machine)
compat = out
if out.Err != nil {
return
}
if out.Status == params.StatusPending {
// The status is pending - there's no point
// in enquiring about the agent liveness.
return
}
agentAlive, err := machine.AgentPresence()
if err != nil {
return
}
if machine.Life() != state.Dead && !agentAlive {
// The agent *should* be alive but is not. Set status to
// StatusDown and munge Info to indicate the previous status and
// info. This is unfortunately making presentation decisions
// on behalf of the client (crappy).
//
// This is munging is only being left in place for
// compatibility with older clients. TODO: At some point we
// should change this so that Info left alone. API version may
// help here.
//
// Better yet, Status shouldn't be changed here in the API at
// all! Status changes should only happen in State. One
// problem caused by this is that this status change won't be
// seen by clients using a watcher because it didn't happen in
// State.

compat.Info = fmt.Sprintf("(%s: %s)", out.Status, out.Info)
} else {
compat.Info = fmt.Sprintf("(%s)", out.Status)
