Regular Reads will block until data is available, but not wait for a full buffer. 
Writes will block until there is space available and writes bigger than the buffer will wait for reads to make space.

`TryRead` and `TryWrite` are still available for non-blocking reads and writes.

## Dépendances pour des groupes de *chemins d'accès* { #dependencies-for-groups-of-path-operations }

Також ваш застосунок **FastAPI** може складатися з кількох файлів/модулів тощо.

### Файл застосунку **FastAPI** { #fastapi-app-file }

Припустимо, у вас є структура файлів, описана в розділі [Bigger Applications](bigger-applications.md):

```
.
├── app
│   ├── __init__.py
│   └── main.py
```

У файлі `main.py` знаходиться ваш застосунок **FastAPI**:


{* ../../docs_src/app_testing/app_a_py310/main.py *}

        assertNotNull(details);
        assertTrue(details.contains("Total: 1 event(s)"));
        assertTrue(details.contains("Something went wrong"));
        // Throwable is no longer included in summary-oriented format
        // Only log message is shown per event line
    }

    @Test
    public void test_formatDetails_emptyList() {

## Dependências para um grupo de *operações de rota* { #dependencies-for-a-group-of-path-operations }

Mais a frente, quando você ler sobre como estruturar aplicações maiores ([Aplicações maiores - Múltiplos arquivos](../../tutorial/bigger-applications.md)), possivelmente com múltiplos arquivos, você aprenderá a declarar um único parâmetro `dependencies` para um grupo de *operações de rota*.

## Dependências globais { #global-dependencies }

  }

  @Test
  @Throws(Exception::class)
  fun timeDurationTruncatedToMaxValue() {
    val cacheControl =
      CacheControl
        .Builder()
        .maxAge(365 * 100, TimeUnit.DAYS) // Longer than Integer.MAX_VALUE seconds.
        .build()
    assertThat(cacheControl.maxAgeSeconds).isEqualTo(Int.MAX_VALUE)
  }

  @Test
  @Throws(Exception::class)
  fun secondsMustBeNonNegative() {

## Настройки в другом модуле { #settings-in-another-module }

Вы можете вынести эти настройки в другой модуль, как показано в разделе [Большие приложения — несколько файлов](../tutorial/bigger-applications.md).

Например, у вас может быть файл `config.py` со следующим содержимым:

{* ../../docs_src/settings/app01_py310/config.py *}

А затем использовать его в файле `main.py`:

    concurrently close an SSL socket. This would have appeared in crash logs as
    `NullPointerException: bio == null`.


## Version 4.9.0

_2020-09-11_

**With this release, `okhttp-tls` no longer depends on Bouncy Castle and doesn't install the
Bouncy Castle security provider.** If you still need it, you can do it yourself:

```
Security.addProvider(BouncyCastleProvider())
```

And your **FastAPI** application might also be composed of several files/modules, etc.

### **FastAPI** app file { #fastapi-app-file }

Let's say you have a file structure as described in [Bigger Applications](bigger-applications.md):

```
.
├── app
│   ├── __init__.py
│   └── main.py
```

In the file `main.py` you have your **FastAPI** app:


{* ../../docs_src/app_testing/app_a_py310/main.py *}

[将 `dependencies` 添加到*路径操作装饰器*](dependencies-in-path-operation-decorators.md) 一章的思路均适用于全局依赖项， 在本例中，这些依赖项可以用于应用中的所有*路径操作*。
