 *  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

* `Field(index=True)` tells SQLModel that it should create a **SQL index** for this column, that would allow faster lookups in the database when reading data filtered by this column.

    SQLModel will know that something declared as `str` will be a SQL column of type `TEXT` (or `VARCHAR`, depending on the database).

### Create an Engine { #create-an-engine }

Los "Context Managers" son aquellos objetos de Python que puedes usar en una declaración `with`.

Por ejemplo, <a href="https://docs.python.org/3/tutorial/inputoutput.html#reading-and-writing-files" class="external-link" target="_blank">puedes usar `with` para leer un archivo</a>:

```Python
with open("./somefile.txt") as f:
    contents = f.read()
    print(contents)
```

      stream.defaultWriteObject();
      stream.writeObject(factory);
      stream.writeObject(backingMap());
    }

    @GwtIncompatible
    @J2ktIncompatible
        @SuppressWarnings("unchecked") // reading data stored by writeObject
    private void readObject(ObjectInputStream stream) throws IOException, ClassNotFoundException {
      stream.defaultReadObject();

            assertTrue(exception.getMessage().contains("jcifs at samba dot org"), "Exception message should contain contact info");
        }
    }

    // String Reading Tests

    @Test

        ByteBuffer bb = ByteBuffer.wrap(testBuffer).order(ByteOrder.LITTLE_ENDIAN);

	}

	// httptest Recorder to capture all the response by the http handler.
	rec := httptest.NewRecorder()
	// reading the body to preserve it so that it can be used again for second attempt of sending unsigned HTTP request.
	// If the body is read in the handler the same request cannot be made use of.
	buf, err := io.ReadAll(anonReq.Body)
