Contributing to Apache Maven
======================

You have found a bug or you have an idea for a cool new feature? Contributing
code is a great way to give something back to the open source community. Before
you dig right into the code, there are a few guidelines that we need
contributors to follow so that we can have a chance of keeping on top of
things.

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

Im Hintergrund erstellt das `open("./somefile.txt")` ein Objekt, das als „Kontextmanager“ bezeichnet wird.

identity and expression, level of experience, education, socio-economic status,
nationality, personal appearance, race, religion, or sexual identity
and orientation.

We pledge to act and interact in ways that contribute to an open, welcoming,
diverse, inclusive, and healthy community.

## Our Standards

Examples of behavior that contributes to a positive environment for our
community includes:

#### Usando `StreamingResponse` con objetos similares a archivos

Si tienes un objeto similar a un archivo (por ejemplo, el objeto devuelto por `open()`), puedes crear una función generadora para iterar sobre ese objeto similar a un archivo.

De esa manera, no tienes que leerlo todo primero en memoria, y puedes pasar esa función generadora al `StreamingResponse`, y devolverlo.

                        .indices()
                        .prepareOpen(docIndex)
                        .execute(ActionListener.wrap(res2 -> logger.info("Open {}", docIndex),
                                e -> logger.warn("Failed to open {}", docIndex, e)));
            }, e -> logger.warn("Failed to close {}", docIndex, e)));
        });
        saveInfo(messages -> messages.addSuccessStartedDataUpdate(GLOBAL));

	if err != nil {
		in.Error("unquoting include file name: ", err)
	}
	in.expectNewline("#include")
	// Push tokenizer for file onto stack.
	fd, err := os.Open(name)
	if err != nil {
		for _, dir := range in.includes {
			fd, err = os.Open(filepath.Join(dir, name))
			if err == nil {
				break
			}
		}
		if err != nil {
			in.Error("#include:", err)
		}
	}

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

Internamente, `open("./somefile.txt")` crea un objeto llamado "Context Manager".

Cuando el bloque `with` termina, se asegura de cerrar el archivo, incluso si hubo excepciones.

		gr, err := objectAPI.GetObjectNInfo(ctx, bucket, zipPath, rs, nil, opts)
		if err != nil {
			writeErrorResponse(ctx, w, toAPIError(ctx, err), r.URL)
			return
		}
		defer gr.Close()
		rc, err = file.Open(gr)
		if err != nil {
			writeErrorResponse(ctx, w, toAPIError(ctx, err), r.URL)
			return
		}
	} else {
		rc = io.NopCloser(bytes.NewReader([]byte{}))
	}

	defer rc.Close()
