### Edit it

It's a very simple program.

But now imagine that you were writing it from scratch.

At some point you would have started the definition of the function, you had the parameters ready...

But then you have to call "that method that converts the first letter to upper case".

Was it `upper`? Was it `uppercase`? `first_uppercase`? `capitalize`?

## About JWT

JWT means "JSON Web Tokens".

It's a standard to codify a JSON object in a long dense string without spaces. It looks like this:

```

```

While a lot of Gradle source code runs only in the Gradle daemon, not all of it does and so, when working on some source code it is important to be aware of the runtimes in which it will run.

See [Gradle runtimes](runtimes.md) for a list of these runtimes and more details.

## Build state model

As Gradle executes, it acts on various pieces of the build definition, such as each project in the build.

 *  Fix: Immediately update the connection's flow control window instead of waiting for the
    receiving stream to process it.

    This change may increase OkHttp's memory use for applications that make many concurrent HTTP
    calls and that can receive data faster than they can process it. Previously, OkHttp limited
    HTTP/2 to 16 MiB of unacknowledged data per connection. With this fix there is a limit of 16 MiB

                it.isDeclaredInOwner() && it.isDelegatedIfRequired()
            }.mapToDelegatedIfRequired()
        }

        override fun getContributedFunctions(name: Name, location: LookupLocation): Collection<SimpleFunctionDescriptor> {
            return allMemberScope.getContributedFunctions(name, location).filter {
                it.isDeclaredInOwner() && it.isDelegatedIfRequired()

!!! note "Technical details"
    In the OpenAPI specification it is called the <a href="https://github.com/OAI/OpenAPI-Specification/blob/main/versions/3.0.3.md#operation-object" class="external-link" target="_blank">Operation Object</a>.

It has all the information about the *path operation* and is used to generate the automatic documentation.

It includes the `tags`, `parameters`, `requestBody`, `responses`, etc.

In the output, you can see that it shows the **PID** (process ID) of each process (it's just a number).

You can see that:

* The Gunicorn **process manager** starts with PID `19499` (in your case it will be a different number).
* Then it starts `Listening at: http://0.0.0.0:80`.
* Then it detects that it has to use the worker class at `uvicorn.workers.UvicornWorker`.

Ztunnel will request certificates for all identities on the node.
It determines this based on the Workload xDS configuration it receives.
When a new identity is discovered on the node, it will be enqueued for fetching at a low priority, as an optimization.
However, if a request needs a certain identity that we have not fetched yet, it will be immediately requested.

                It will be included in the generated OpenAPI (e.g. visible at `/docs`).
