### Écrire votre propre code async { #write-your-own-async-code }

Starlette (et **FastAPI**) s’appuie sur [AnyIO](https://anyio.readthedocs.io/en/stable/), ce qui le rend compatible à la fois avec la bibliothèque standard [asyncio](https://docs.python.org/3/library/asyncio-task.html) de Python et avec [Trio](https://trio.readthedocs.io/en/stable/).

### SIG Azure

* The Azure cloud provider now supports standard SKU load balancer and public IP.
`excludeMasterFromStandardLB` defaults to true, which means master nodes are excluded from the standard load balancer. Also note that because all nodes (except master) are added as loadbalancer backends, the standard load balancer doesn't work with the `service.beta.kubernetes.io/azure-load-balancer-mode` annotation.

	c_ISUID = 04000 // Set uid
	c_ISGID = 02000 // Set gid
	c_ISVTX = 01000 // Save text (sticky bit)

	// Common Unix mode constants; these are not defined in any common tar standard.
	// Header.FileInfo understands these, but FileInfoHeader will never produce these.
	c_ISDIR  = 040000  // Directory
	c_ISFIFO = 010000  // FIFO
	c_ISREG  = 0100000 // Regular file

```

* And it upgrades `fastapi-cli[standard] >=0.0.5`.

#### Technical Details

Before this, `fastapi` would include the standard dependencies, with Uvicorn and the `fastapi-cli`, etc.

And `fastapi-slim` would not include those standard dependencies.

Now `fastapi` doesn't include those standard dependencies unless you install with `pip install "fastapi[standard]"`.

Versiyon aralıklarını belirlemek için elbette [FastAPI sürümleri hakkında](versions.md) bölümünde okuduğunuz fikirleri kullanırsınız.

Örneğin `requirements.txt` şöyle görünebilir:

```
fastapi[standard]>=0.113.0,<0.114.0
pydantic>=2.7.0,<3.0.0
```

Ve bu bağımlılıkları normalde `pip` ile yüklersiniz, örneğin:

<div class="termy">

```console
$ pip install -r requirements.txt
---> 100%

	if userDefined["content-type"] == "" {
		userDefined["content-type"] = mimedb.TypeByExtension(path.Ext(object))
	}

	// if storageClass is standard no need to save it as part of metadata.
	if userDefined[xhttp.AmzStorageClass] == storageclass.STANDARD {
		delete(userDefined, xhttp.AmzStorageClass)
	}

	// Fill all the necessary metadata.
	// Update `xl.meta` content on each disks.

Por supuesto, usarías las mismas ideas que leíste en [Acerca de las versiones de FastAPI](versions.md) para establecer los rangos de versiones.

Por ejemplo, tu `requirements.txt` podría verse así:

```
fastapi[standard]>=0.113.0,<0.114.0
pydantic>=2.7.0,<3.0.0
```

Y normalmente instalarías esas dependencias de los paquetes con `pip`, por ejemplo:

<div class="termy">

```console
$ pip install -r requirements.txt
