/// tip

You can actually use this same technique with an HTTP `PUT` operation.

But the example here uses `PATCH` because it was created for these use cases.

Notice that the input model is still validated.

# Extending OpenAPI { #extending-openapi }

There are some cases where you might need to modify the generated OpenAPI schema.

In this section you will see how.

## The normal process { #the-normal-process }

The normal (default) process, is as follows.

A `FastAPI` application (instance) has an `.openapi()` method that is expected to return the OpenAPI schema.

    /**
     * {@return the dependency scope for the given identifier, or {@code null} if none}.
     * The identifiers are usually in lower cases with {@code '-'} instead of {@code '_'}
     * as word separator.
     *
     * @param id the identifier of the scope (case-sensitive)
     */
    public static DependencyScope forId(String id) {

Before making code changes, make sure you create a separate branch for these changes

```
git checkout -b my-new-feature

### Test MinIO server changes

After your code changes, make sure

- To add test cases for the new code. If you have questions about how to do it, please ask on our [Slack](https://slack.min.io) channel.
- To run `make verifiers`

# HTTP Basic Auth { #http-basic-auth }

For the simplest cases, you can use HTTP Basic Auth.

In HTTP Basic Auth, the application expects a header that contains a username and a password.

If it doesn't receive it, it returns an HTTP 401 "Unauthorized" error.

And returns a header `WWW-Authenticate` with a value of `Basic`, and an optional `realm` parameter.

That tells the browser to show the integrated prompt for a username and password.

			// true if the source file path contains an non-existent directory. In that case,
			// we want to return errFileNotFound instead, which will honored in subsequent
			// switch cases
			return errFileAccessDenied
		case isSysErrPathNotFound(err):

			// windows, because windows API does not return "not a

Write throughput is typically at least 500MB/s per CPU core,
and scales with the number of available CPU cores.
Decompression speed is typically at least 1GB/s.

This means that in cases where raw IO is below these numbers
compression will not only reduce disk usage but also help increase system throughput.
Typically, enabling compression on spinning disk systems
will increase speed when the content can be compressed.
