# Development - Contributing

First, you might want to see the basic ways to [help FastAPI and get help](help-fastapi.md){.internal-link target=_blank}.

## Developing

If you already cloned the <a href="https://github.com/fastapi/fastapi" class="external-link" target="_blank">fastapi repository</a> and you want to deep dive in the code, here are some guidelines to set up your environment.

### Virtual environment

						}
						b.Fatal(err.Error())
					}
					got := 0
					for i := 0; i < requests; i++ {
						got++
						st.Requests <- append(GetByteBuffer()[:0], payload...)
					}
					close(st.Requests)
					err = st.Results(func(b []byte) error {
						return nil
					})
					if err != nil {
						if debugReqs {
							fmt.Println(err.Error())
						}
						b.Fatal(err.Error())
					}

			bytesReturned := atomic.LoadInt64(&writer.bytesReturned)
			if !writer.write(newProgressMessage(bytesScanned, bytesProcessed, bytesReturned)) {
				quitFlag = true
			}
		}
	}
	close(writer.doneCh)

	recordStagingTicker.Stop()
	keepAliveTicker.Stop()
	if progressTicker != nil {
		progressTicker.Stop()
	}

	// Whatever drain the payloadCh to prevent from memory leaking.

			xioutil.SafeClose(c.done)
			c.done = nil
		}
	}
	return n, err
}

func (c *closeNotifier) Close() error {
	if c.done != nil {
		xioutil.SafeClose(c.done)
		c.done = nil
	}
	return c.rc.Close()
}

// keepHTTPReqResponseAlive can be used to avoid timeouts with long storage
// operations, such as bitrot verification or data usage scanning.
// Every 10 seconds a space character is sent.

                int length,
                boolean isDirect) throws IOException;
    protected abstract void doReceiveFragment(byte[] buf, boolean isDirect) throws IOException;
    public abstract void close() throws IOException;

        And there's a high chance that you will find the solution along the way and you won't even have to submit it and wait for an answer. 😎

        As there are too many questions, I'll have to discard and close the incomplete ones. That will allow me (and others) to focus on helping people like you that follow the whole process and help us help you. 🤓
