### Feature

- A new histogram metric to track the time it took to delete a job by the ttl-after-finished controller ([#98676](https://github.com/kubernetes/kubernetes/pull/98676), [@ahg-g](https://github.com/ahg-g)) [SIG Apps and Instrumentation]

1. This is the generator function. It's a "generator function" because it contains `yield` statements inside.
2. By using a `with` block, we make sure that the file-like object is closed after the generator function is done. So, after it finishes sending the response.
3. This `yield from` tells the function to iterate over that thing named `file_like`. And then, for each part iterated, yield that part as coming from this generator function (`iterfile`).

```Python
with open("./somefile.txt") as f:
    contents = f.read()
    print(contents)
```

Underneath, the `open("./somefile.txt")` creates an object that is called a "Context Manager".

When the `with` block finishes, it makes sure to close the file, even if there were exceptions.

When you create a dependency with `yield`, **FastAPI** will internally create a context manager for it, and combine it with some other related tools.

        snapshot1.assertValue(1, "a")
        snapshot2.assertValue(1, "a")
      }
    }
  }

  @Test
  fun `remove while reading creates zombie that is removed when read finishes`() {
    val afterRemoveFileContents = if (windows) "a" else null

    set("k1", "a", "a")
    cache["k1"]!!.use { snapshot1 ->
      cache.remove("k1")

- Only declare Job as finished after removing all Pod finalizers to avoid orphan Pods ([#119163](https://github.com/kubernetes/kubernetes/pull/119163), [@alculquicondor](https://github.com/alculquicondor)) [SIG Apps and Testing]

- Finished initial generic controlplane refactor of kube-apiserver, providing a sample binary building a Kubernetes-like control plane, but without container orchestration resources. ([#124530](https://github.com/kubernetes/kubernetes/pull/124530), [@sttts...

  public void testInvalidateDuringLoading() throws InterruptedException, ExecutionException {
    // computation starts; invalidate() is called on the key being computed, computation finishes
    CountDownLatch computationStarted = new CountDownLatch(2);
    CountDownLatch letGetFinishSignal = new CountDownLatch(1);
    CountDownLatch getFinishedSignal = new CountDownLatch(2);
    String getKey = "get";

  public void testInvalidateDuringLoading() throws InterruptedException, ExecutionException {
    // computation starts; invalidate() is called on the key being computed, computation finishes
    CountDownLatch computationStarted = new CountDownLatch(2);
    CountDownLatch letGetFinishSignal = new CountDownLatch(1);
    CountDownLatch getFinishedSignal = new CountDownLatch(2);
    String getKey = "get";

This was designed this way mainly to allow using the same objects "yielded" by dependencies inside of background tasks, because the exit code would be executed after the background tasks were finished.

Nevertheless, as this would mean waiting for the response to travel through the network while unnecessarily holding a resource in a dependency with yield (for example a database connection), this was changed in FastAPI 0.106.0.
