#### Sử dụng `Union` hay `Optional`

If you are using a Python version below 3.10, here's a tip from my very **subjective** point of view:

Nếu bạn đang sử dụng phiên bản Python dưới 3.10, đây là một mẹo từ ý kiến rất "chủ quan" của tôi:

* 🚨 Tránh sử dụng `Optional[SomeType]`

        assertTrue(toStringResult.contains("queryTime=500"));
        assertTrue(toStringResult.contains("partialResults=false"));
    }

    public void test_calculatePageInfo_extremeValues() {
        // Test with very large record count
        QueryResponseList qrList = new QueryResponseList(null, 0, 100, 0) {
            @Override
            public int size() {
                return 100;
            }
        };

	if err != nil {
		t.Fatalf("os.Stat:1 %v", err)
	}
	hdr.Typeflag = TypeDir
	// Force a PAX long name to be written. The name was taken from a practical example
	// that fails and replaced ever char through numbers to anonymize the sample.

    ```java
        RequestBody.create(null, new byte[0]);
    ```

 * **`CertificatePinner` now supports wildcard hostnames.** As always with
   certificate pinning, you must be very careful to avoid [bricking][brick]
   your app. You'll need to pin both the top-level domain and the `*.` domain
   for full coverage.

    ```java
     client.setCertificatePinner(new CertificatePinner.Builder()

		return err
	}
	b := readBuf(buf[:12])
	if b.uint32() != f.CRC32 {
		return ErrChecksum
	}

	// The two sizes that follow here can be either 32 bits or 64 bits
	// but the spec is not very clear on this and different
	// interpretations has been made causing incompatibilities. We
	// already have the sizes from the central directory so we can
	// just ignore these.

	return nil
}

 *  Fix: `OkHttpClient` no longer implements `Cloneable`. It never should have; the class is
    immutable. This is left over from OkHttp 2.x (!) when that class was mutable. We're using the
    5.x upgrade as an opportunity to remove very obsolete APIs.
 *  Fix: Recover gracefully when Android's `NativeCrypto` crashes with `"ssl == null"`. This occurs
    when OkHttp retrieves ALPN state on a closed connection.
 *  Upgrade: [Kotlin 1.6.21][kotlin_1_6_21].

   *
   * <p>The temporary directory is created with permissions restricted to the current user or, in
   * the case of Android, the current app. If that is not possible (as is the case under the very
   * old Android Ice Cream Sandwich release), then this method throws an exception instead of
   * creating a directory that would be more accessible. (This behavior is new in Guava 32.0.0.
