示例1: TestStaleUpdates

func TestStaleUpdates(t *testing.T) {
	pod := getTestPod()
	client := fake.NewSimpleClientset(pod)
	m := newTestManager(client)

	status := v1.PodStatus{Message: "initial status"}
	m.SetPodStatus(pod, status)
	status.Message = "first version bump"
	m.SetPodStatus(pod, status)
	status.Message = "second version bump"
	m.SetPodStatus(pod, status)
	verifyUpdates(t, m, 3)

	t.Logf("First sync pushes latest status.")
	m.testSyncBatch()
	verifyActions(t, m.kubeClient, []core.Action{
		core.GetActionImpl{ActionImpl: core.ActionImpl{Verb: "get", Resource: schema.GroupVersionResource{Resource: "pods"}}},
		core.UpdateActionImpl{ActionImpl: core.ActionImpl{Verb: "update", Resource: schema.GroupVersionResource{Resource: "pods"}, Subresource: "status"}},
	})
	client.ClearActions()

	for i := 0; i < 2; i++ {
		t.Logf("Next 2 syncs should be ignored (%d).", i)
		m.testSyncBatch()

	}

	t.Log("Unchanged status should not send an update.")
	m.SetPodStatus(pod, status)
	verifyUpdates(t, m, 0)

	t.Log("... unless it's stale.")
	m.apiStatusVersions[pod.UID] = m.apiStatusVersions[pod.UID] - 1

示例2: updateStatusInternal

// updateStatusInternal updates the internal status cache, and queues an update to the api server if
// necessary. Returns whether an update was triggered.
// This method IS NOT THREAD SAFE and must be called from a locked function.
func (m *manager) updateStatusInternal(pod *v1.Pod, status v1.PodStatus, forceUpdate bool) bool {
	var oldStatus v1.PodStatus
	cachedStatus, isCached := m.podStatuses[pod.UID]
	if isCached {
		oldStatus = cachedStatus.status
	} else if mirrorPod, ok := m.podManager.GetMirrorPodByPod(pod); ok {
		oldStatus = mirrorPod.Status
	} else {
		oldStatus = pod.Status
	}

	// Set ReadyCondition.LastTransitionTime.
	if _, readyCondition := v1.GetPodCondition(&status, v1.PodReady); readyCondition != nil {

	}

	// ensure that the start time does not change across updates.
	if oldStatus.StartTime != nil && !oldStatus.StartTime.IsZero() {
		status.StartTime = oldStatus.StartTime
	} else if status.StartTime.IsZero() {
		// if the status has no start time, we need to set an initial time
		now := metav1.Now()
		status.StartTime = &now
	}

	normalizeStatus(pod, &status)
	// The intent here is to prevent concurrent updates to a pod's status from
	// clobbering each other so the phase of a pod progresses monotonically.
	if isCached && isStatusEqual(&cachedStatus.status, &status) && !forceUpdate {
		glog.V(3).Infof("Ignoring same status for pod %q, status: %+v", format.Pod(pod), status)
		return false // No new status.
	}

	newStatus := versionedPodStatus{
		status:       status,
		version:      cachedStatus.version + 1,
		podName:      pod.Name,

	m.podStatuses[pod.UID] = newStatus

	select {
	case m.podStatusChannel <- podStatusSyncRequest{pod.UID, newStatus}:
		return true
	default:
		// Let the periodic syncBatch handle the update if the channel is full.
		// We can't block, since we hold the mutex lock.
		glog.V(4).Infof("Skpping the status update for pod %q for now because the channel is full; status: %+v",
			format.Pod(pod), status)
		return false
	}
