**5. Copy to Google Internal codebase and run internal CI**

-   Once the PR is in the Google codebase, we make sure it integrates well with
    its dependencies and the rest of the system.
-   Rarely, If the tests fail at this stage, we cannot merge the code.
-   If needed, we may come to you to make some changes. At times, it may not be

running specific tests that rely on them.

For example, we have an hdfs test that uses mini-hdfs to test our
repository-hdfs plugin.

#### `x-pack`
Commercially licensed code that integrates with the rest of Elasticsearch. The
`docs` subdirectory functions just like the top level `docs` subdirectory and
the `qa` subdirectory functions just like the top level `qa` subdirectory. The

    HTTP/1.1. We also reimplemented our websocket client to use this new mechanism.

 *  New: The `okhttp-zstd` module negotiates [Zstandard (zstd)][zstd] compression with servers that
    support it. It integrates a new (unstable) [ZSTD-KMP] library, also from Square. Enable it like
    this:

    ```kotlin
    val client = OkHttpClient.Builder()
      .addInterceptor(CompressionInterceptor(Zstd, Gzip))
      .build()
    ```

## Integrando com OpenAPI { #integrated-with-openapi }

Todas as declarações de requisições, validações e requisitos para suas dependências (e sub-dependências) serão integradas em um mesmo esquema OpenAPI.

Então, a documentação interativa também terá toda a informação sobre essas dependências:

* **Sin complicaciones**:
    * Sin micro-lenguaje de definición de esquemas nuevo que aprender.
    * Si conoces los tipos en Python sabes cómo usar Pydantic.
* Se lleva bien con tu **<abbr title="Integrated Development Environment – Entorno de Desarrollo Integrado: similar a un editor de código">IDE</abbr>/<dfn title="Un programa que verifica errores de código">linter</dfn>/cerebro**:

///

## Intégrer à OpenAPI { #integrated-with-openapi }

Toutes les déclarations de requête, validations et exigences de vos dépendances (et sous-dépendances) seront intégrées dans le même schéma OpenAPI.

Ainsi, la documentation interactive contiendra aussi toutes les informations issues de ces dépendances :

* **Pas de prise de tête** :
    * Pas de micro-langage de définition de schéma à apprendre.
    * Si vous connaissez les types Python vous savez utiliser Pydantic.
* Fonctionne bien avec votre **<abbr title="Integrated Development Environment - Environnement de développement intégré: similaire à un éditeur de code">IDE</abbr>/<dfn title="Programme qui vérifie les erreurs de code">linter</dfn>/cerveau** :

Then you can give this token to a user directly or a third party, to interact with your API with a set of restrictions.

You can learn how to use them and how they are integrated into **FastAPI** later in the **Advanced User Guide**.

## Recap { #recap }

With what you have seen up to now, you can set up a secure **FastAPI** application using standards like OAuth2 and JWT.
