 *  Fix: Don't leak file handles when a cache disk write fails.

 *  Fix: Don't hang when the public suffix database cannot be loaded. We had a bug where a failure
    reading the public suffix database would cause subsequent reads to hang when they should have
    crashed.

 *  Fix: Avoid `InetAddress.getCanonicalHostName()` in MockWebServer. This avoids problems if the

        .connect()
      fail<Any>()
    } catch (expected: ConnectException) {
    }

FastAPI là một web framework hiện đại, hiệu năng cao để xây dựng web APIs với Python dựa trên tiêu chuẩn Python type hints.

Những tính năng như:

* **Nhanh**: Hiệu năng rất cao khi so sánh với **NodeJS** và **Go** (cảm ơn Starlette và Pydantic). [Một trong những Python framework nhanh nhất](#hieu-nang).
* **Code nhanh**: Tăng tốc độ phát triển tính năng từ 200% tới 300%. *

     */
    public static final ArtifactStatus DEPLOYED = new ArtifactStatus("deployed", 4);

    /**
     * Trusted, as it has had its data verified by hand.
     */
    public static final ArtifactStatus VERIFIED = new ArtifactStatus("verified", 5);

    private final int rank;

    private final String key;

    private static Map<String, ArtifactStatus> map;

And then they can try again knowing that it's probably something more similar to `stanleyjobsox` than to `johndoe`.

#### A "professional" attack { #a-professional-attack }

Of course, the attackers would not try all this by hand, they would write a program to do it, possibly with thousands or millions of tests per second. And they would get just one extra correct letter at a time.
