### Threads

#### Application's calling thread

The application-layer must block on writing I/O. We can't return from a write until we've pushed its bytes onto the socket. Otherwise, if the write fails we are unable to deliver its IOException to the application. We would have told the application layer that the write succeeded, but it didn't!

* `users:read` oder `users:write` sind gängige Beispiele.
* `instagram_basic` wird von Facebook / Instagram verwendet.
* `https://www.googleapis.com/auth/drive` wird von Google verwendet.

In OAuth2 ist ein „Scope“ nur ein String, der eine bestimmte erforderliche Berechtigung deklariert.

        // Configure mocks for NdrBuffer interactions
        lenient().when(mockDeferredBuffer.derive(anyInt())).thenReturn(mockDeferredBuffer);
        lenient().doNothing().when(mockDeferredBuffer).advance(anyInt());
        // Set up index field for derive operations
        mockDeferredBuffer.index = 0;
    }

각 "범위"는 공백이 없는 문자열입니다.

일반적으로 특정 보안 권한을 선언하는 데 사용됩니다. 다음을 봅시다:

* `users:read` 또는 `users:write`는 일반적인 예시입니다.
* `instagram_basic`은 페이스북/인스타그램에서 사용합니다.
* `https://www.googleapis.com/auth/drive`는 Google에서 사용합니다.

/// info | 정보

OAuth2에서 "범위"는 필요한 특정 권한을 선언하는 문자열입니다.

`:`과 같은 다른 문자가 있는지 또는 URL인지는 중요하지 않습니다.

이러한 세부 사항은 구현에 따라 다릅니다.

OAuth2의 경우 문자열일 뿐입니다.

func (set *erasureObjects) listObjectsToDecommission(ctx context.Context, bi decomBucketInfo, fn func(entry metaCacheEntry)) error {
	disks, _ := set.getOnlineDisksWithHealing(false)
	if len(disks) == 0 {
		return fmt.Errorf("no online drives found for set with endpoints %s", set.getEndpoints())
	}

	// However many we ask, versions must exist on ~50%
	listingQuorum := (set.setDriveCount + 1) / 2

	// How to resolve partial results.

Normalmente são usados para declarar permissões de segurança específicas, por exemplo:

* `users:read` ou `users:write` são exemplos comuns.
* `instagram_basic` é usado pelo Facebook e Instagram.
* `https://www.googleapis.com/auth/drive` é usado pelo Google.

/// info | Informação

No OAuth2, um "scope" é apenas uma string que declara uma permissão específica necessária.

Não importa se tem outros caracteres como `:` ou se é uma URL.
