## Pre-pre requisite

- A working knowledge of MinIO codebase and its various components.
- A working knowledge of AWS S3 API behaviors and corner cases.

## Pre-requisite for backporting any fixes

Fixes that are allowed a backport must satisfy any of the following criteria's:

- A fix must not be a feature, for example.

```

                // Referenced ClassId and qualified access (from source PSI) could be not identical if an import alias is involved.
                // E.g., test.pkg.R.string.hello v.s. coreR.string.hello where test.pkg.R is imported as coreR
                // Since an import alias ends with a simple identifier (i.e., can't be non-trivial dotted qualifier), we can safely assume

Sie bekommen sogar Autovervollständigung an Stellen, an denen Sie dies vorher nicht für möglich gehalten hätten. Zum Beispiel der `price` Schlüssel in einem JSON Datensatz (dieser könnte auch verschachtelt sein), der aus einer Anfrage kommt.

!!! check "Authorize button!"
    You already have a shiny new "Authorize" button.

    And your *path operation* has a little lock in the top-right corner that you can click.

And if you click it, you have a little authorization form to type a `username` and `password` (and other optional fields):

Authorize the application the same way as before.

Using the credentials:

Username: `johndoe`
Password: `secret`

!!! check
    Notice that nowhere in the code is the plaintext password "`secret`", we only have the hashed version.

Call the endpoint `/users/me/`, you will get the response as:

sight, hurrying down it.  There was not a moment to be lost:
away went Alice like the wind, and was just in time to hear it
say, as it turned a corner, `Oh my ears and whiskers, how late
it's getting!'  She was close behind it when she turned the
corner, but the Rabbit was no longer to be seen:  she found
herself in a long, low hall, which was lit up by a row of lamps
hanging from the roof.

* A encriptação da conexão acontece no nível TCP.
    * TCP é uma camada abaixo do HTTP.
    * Então, o controle de certificado e encriptação é feito antes do HTTP.
* TCP não conhece nada sobre "domínios". Somente sobre endereços IP.
    * A informação sobre o domínio requisitado vai nos dados HTTP.

Então o caixa diz que "seus hambúrgueres estão prontos" colocando seu número no balcão, mas você não corre que nem um maluco imediatamente quando o número exibido é o seu. Você sabe que ninguém irá roubar seus hambúrgueres porquê você tem o número de chamada, e os outros tem os números deles.
