#### How relative imports work

!!! tip
    If you know perfectly how imports work, continue to the next section below.

A single dot `.`, like in:

```Python
from .dependencies import get_token_header
```

would mean:

   * Fully maps a file read-only in to memory as per {@link
   * FileChannel#map(java.nio.channels.FileChannel.MapMode, long, long)}.
   *
   * <p>Files are mapped from offset 0 to its length.
   *
   * <p>This only works for files ≤ {@link Integer#MAX_VALUE} bytes.
   *
   * @param file the file to map
   * @return a read-only buffer reflecting {@code file}
   * @throws FileNotFoundException if the {@code file} does not exist

Unit tests

```
λ make test
```

Verify different type of MinIO deployments work

```
λ make verify
```

Verify if healing and replacing a drive works

```
λ make verify-healing
```

Чтобы **изучить основы HTTPS** для клиента, перейдите по ссылке <a href="https://howhttps.works/" class="external-link" target="_blank">https://howhttps.works/</a>.

Здесь же представлены некоторые концепции, которые **разработчик** должен иметь в виду при размышлениях об HTTPS:

        List<Iterable<T>> words = Lists.newArrayList();
        words.add(Collections.<T>emptyList());
        for (T t : scenario.strictlyOrderedList) {
          words.add(Arrays.asList(t));
          for (T s : scenario.strictlyOrderedList) {
            words.add(Arrays.asList(t, s));
          }
        }

We will create a `PeeweeConnectionState`:

```Python hl_lines="10-19"
{!../../../docs_src/sql_databases_peewee/sql_app/database.py!}
```

This class inherits from a special internal class used by Peewee.

It has all the logic to make Peewee use `contextvars` instead of `threading.local`.
