Comment cela fonctionne-t-il ? Voyons cela. 🤓

### Annotations de type et outils { #type-annotations-and-tooling }

Voyons d'abord comment les éditeurs, mypy et autres outils considèreraient cela.

    @ParametricNullness final K key;
    @ParametricNullness final V value;

    final int keyHash;
    final int valueHash;

    // All Node instances are strongly reachable from owning HashBiMap through
    // "HashBiMap.hashTableKToV" and "Node.nextInKToVBucket" references.
    // Under that assumption, the remaining references can be safely marked as @Weak.

                    name, currentState, totalRequests, totalSuccesses, totalFailures, totalRejections, successRate, availability);
        }
    }

    /**
     * Hystrix-style rolling window for time-based metrics collection
     */
    private static class RollingWindow {
        private final int numberOfBuckets;
        private final long bucketSizeInMillis;

이를 통해 이 코드는 타입 관점에서 올바르므로 에디터와 mypy 등의 도구 지원을 받을 수 있고, 동시에 FastAPI의 데이터 필터링도 받을 수 있습니다.

이게 어떻게 동작할까요? 확인해 봅시다. 🤓

### 타입 어노테이션과 도구 지원 { #type-annotations-and-tooling }

먼저 에디터, mypy 및 기타 도구가 이를 어떻게 보는지 살펴봅시다.

`BaseUser`는 기본 필드를 가집니다. 그리고 `UserIn`은 `BaseUser`를 상속하고 `password` 필드를 추가하므로, 두 모델의 모든 필드를 포함하게 됩니다.

함수 반환 타입을 `BaseUser`로 어노테이션하지만, 실제로는 `UserIn` 인스턴스를 반환합니다.

door as you are; secondly, because they're making such a noise
inside, no one could possibly hear you.'  And certainly there was
a most extraordinary noise going on within--a constant howling
and sneezing, and every now and then a great crash, as if a dish
or kettle had been broken to pieces.

  `Please, then,' said Alice, `how am I to get in?'

这样一来，我们既能从编辑器和 mypy 获得工具支持（这段代码在类型上是正确的），也能从 FastAPI 获得数据过滤。

这是如何做到的？我们来看看。🤓

### 类型注解与工具链 { #type-annotations-and-tooling }

先看看编辑器、mypy 和其他工具会如何看待它。

`BaseUser` 有基础字段。然后 `UserIn` 继承自 `BaseUser` 并新增了 `password` 字段，因此它包含了两个模型的全部字段。

我们把函数返回类型注解为 `BaseUser`，但实际上返回的是一个 `UserIn` 实例。

	}
	h.ignoreNilConn = true
	return h
}

// WithSharedResponse indicates it is unsafe to reuse the response
// when it has been returned on a handler.
// This will disable automatic response recycling/pooling.
// Typically this is used when the response sharing part of its data structure.
func (h *SingleHandler[Req, Resp]) WithSharedResponse() *SingleHandler[Req, Resp] {
	h.sharedResp = true
	return h
}

* Stateful Apps:
  * **alpha** PetSets manage stateful apps
  * **alpha** Init containers provide one-time setup for stateful containers
* Updating:
  * Retry Pod/RC updates in kubectl rolling-update.
  * Stop 'kubectl drain' deleting pods with local storage.
  * Add `kubectl rollout status`
* Security/Auth
  * L7 LB controller and disk attach controllers run on master, so nodes do not need those privileges.

debating the need for a debug utility for quite some time already. With the development of [ephemeral containers](https://kubernetes.io/docs/concepts/workloads/pods/ephemeral-containers/), it became more obvious how we can support developers with tooling built on top of `kubectl exec`. The addition of the `kubectl debug` [command](https://github.com/kubernetes/enhancements/blob/master/keps/sig-cli/1441-kubectl-debug/README.md) (it is alpha but your feedback is more than welcome), allows developers...

    the stream only or the entire connection. With this fix OkHttp will now send HTTP/2 pings after
    a stream timeout to determine whether the connection should remain eligible for pooling.

 *  Fix: Cancel calls that fail due to unexpected exceptions. We had a bug where an enqueued call
    would never call back if it crashed with an unchecked throwable, such as a
