Next, it 🤖 takes the first task to finish (let's say, our "slow-file" 📝) and continues whatever it had to do with it.

Aso, when returning several objects, like in `get_users`, we directly call `list`, like in:

```Python
list(models.User.select())
```

    }.also { expected ->
      assertThat(expected).hasMessage("timeout")
    }
  }

  /**
   * This test reproduces a crash where OkHttp attempted to use a deferred connection when the call
   * already had a healthy connection. It sets up a deferred connection by stalling the IPv6
   * connect, and it sets up a same-connection retry with [ErrorCode.REFUSED_STREAM].

  /** Though this executor service may hold many threads, they are not executed concurrently. */
  private val tasksExecutor = Executors.newCachedThreadPool(threadFactory("TaskFaker"))

  /**
   * True if this task faker has ever had multiple tasks scheduled to run concurrently. Guarded by

   * successful. This test confirms that connections are released back to the connection pool!

    non-ASCII characters (including international characters and emoji).

 *  **Call canceling is more reliable.**  We had a bug where a socket being
     connected wasn't being closed when the application used `Call.cancel()`.

 *  **Changing a HttpUrl’s scheme now tracks the default port.** We had a bug
    where changing a URL from `http` to `https` would leave it on port 80.

 *  **Okio has been updated to 1.6.0.**

    for a graceful shutdown before it performs an abrupt shutdown.

 *  Fix: Honor `RequestBody.isOneShot()` in `MultipartBody`

 *  Fix in `okhttp-coroutines`: Don't leak response bodies in `executeAsync()`. We had a bug where
    we didn't call `Response.close()` if the coroutine was canceled before its response was
    returned.

 *  Upgrade: [Okio 3.9.0][okio_3_9_0].

 *  Upgrade: [Kotlin 1.9.23][kotlin_1_9_23].

Now it's the time to use it with FastAPI. 🚀

We had this type annotation:

=== "Python 3.10+"

    ```Python
    q: str | None = None
    ```

=== "Python 3.8+"

    ```Python
    q: Union[str, None] = None
    ```

A secondary goal was to enable a smoother on-ramp from "Zero" to "Getting some value".
Historically, Istio had to really be consumed all-or-nothing for things to work as expected.
In particular, an easy answer to "I just want to have mTLS everywhere, then I can think about adopting the rest of service mesh" was desired.

## Goals

## Version 4.7.2

_2020-05-20_

 *  Fix: Don't crash inspecting whether the host platform is JVM or Android. With 4.7.0 and 4.7.1 we
    had a crash `IllegalArgumentException: Not a Conscrypt trust manager` because we depended on
    initialization order of companion objects.


## Version 4.7.1
