Adds unit tests covering the problematic scenarios identified
around conflicting data in child owner references
Before After
package level 51% 68%
garbagecollector.go 60% 75%
graph_builder.go 50% 81%
graph.go 50% 68%
Added/improved coverage of key functions that had lacking unit test coverage:
* attemptToDeleteWorker
* attemptToDeleteItem
* processGraphChanges (added coverage of all added code)
- as soon as a request is received by the apiserver, determine the
timeout of the request and set a new request context with the deadline.
- the timeout filter that times out non-long-running requests should
use the request context as opposed to a fixed 60s wait today.
- admission and storage layer uses the same request context with the
deadline specified.
The test code generation for create subresource was missing the resource
name parameter in the template which caused a compile error for the
sample projects using the scale subresource. That only occurs with
non-namespaced resource kind.
Also re-ran the code generation after applying the fix.
* Mixed protocol support for Services with type=LoadBalancer
KEP: https://github.com/kubernetes/enhancements/blob/master/keps/sig-network/20200103-mixed-protocol-lb.md
Add new feature gate to control the support of mixed protocols in Services with type=LoadBalancer
Add new fields to the ServiceStatus
Add Ports to the LoadBalancerIngress, so cloud provider implementations can report the status of the requested load balanc
er ports
Add ServiceCondition to the ServiceStatus so Service controllers can indicate the conditions of the Service
* regenerate conflicting stuff
Implements KEP 2000, Graceful Node Shutdown:
https://github.com/kubernetes/enhancements/tree/master/keps/sig-node/2000-graceful-node-shutdown
* Add new FeatureGate `GracefulNodeShutdown` to control
enabling/disabling the feature
* Add two new KubeletConfiguration options
* `ShutdownGracePeriod` and `ShutdownGracePeriodCriticalPods`
* Add new package, `nodeshutdown` that implements the Node shutdown
manager
* The node shutdown manager uses the systemd inhibit package, to
create an system inhibitor, monitor for node shutdown events, and
gracefully terminate pods upon a node shutdown.
Changed quantization to use monotonic clock readings.
Stopping panicing when monotonic clock readings go backwards because
https://github.com/kubernetes/kubernetes/issues/96459 reported it
happening.
Re-organized sampleAndWaterMarkHistograms::innerSet to `defer` the
Unlock call, because that is the preferred pattern.
- Remove feature gate consideration from EndpointSlice validation
- Deprecate topology field, note that it will be removed in future
release
- Update kube-proxy to check for NodeName if feature gate is enabled
- Add comments indicating the feature gates that can be used to enable
alpha API fields
- Add comments explaining use of deprecated address type in tests
