## Version 4.3.0

_2019-12-31_

 *  Fix: Degrade HTTP/2 connections after a timeout. When an HTTP/2 stream times out it may impact
    the stream only or the entire connection. With this fix OkHttp will now send HTTP/2 pings after
    a stream timeout to determine whether the connection should remain eligible for pooling.

                            }

Timing (DIT) modes in the [`crypto/subtle`](/pkg/crypto/subtle) package. This
mode can be enabled for an entire program with the `dataindependenttiming` setting.
For Go 1.24 it defaults to `dataindependenttiming=0`. There is no change in default
behavior from Go 1.23 when `dataindependenttiming` is unset.
Using `dataindependenttiming=1` enables the DIT mode for the entire Go program.
When enabled, DIT will be enabled when calling into C from Go. When enabled,

## Motivation

Fangen wir mit einem einfachen Beispiel an:

C'est pourquoi, comme le dit le site officiel :

> Requests est l'un des packages Python les plus téléchargés de tous les temps

La façon dont vous l'utilisez est très simple. Par exemple, pour faire une requête `GET`, vous devez écrire :

```Python
response = requests.get("http://example.com/some/url")
```

En contrepartie l'API _des opérations de chemin_ de FastAPI pourrait ressembler à ceci :

```Python hl_lines="1"

	if !cred.IsServiceAccount() && cred.IsTemp() && subtle.ConstantTimeCompare([]byte(token), []byte(cred.SessionToken)) != 1 {
		// validate token for temporary credentials only.
		return nil, ErrInvalidToken
	}

	// Expired credentials must return error right away.
	if cred.IsTemp() && cred.IsExpired() {
		return nil, toAPIErrorCode(r.Context(), errInvalidAccessKeyID)
	}
	secret := globalActiveCred.SecretKey

			// Just return the first error.
			return err
		}
		d.Policy = doc.Policy
		return nil
	}
	*d = doc
	return nil
}

// key options
type options struct {
	ttl int64 // expiry in seconds
}

type iamWatchEvent struct {
	isCreated bool // !isCreated implies a delete event.
	keyPath   string
}

// iamCache contains in-memory cache of IAM data.
type iamCache struct {
