Multiplexing an echo server using Diesel concurrent library

Sometimes you need to write a large custom networking application that wants to avoid repeated server initialization code that creates a socket, binds to an address, listens, and handles basic errors. There are numerous Python networking libraries out there to help you remove boiler-plate code. Here, we can examine such a library called Diesel.

Getting ready

Diesel uses a non-blocking technique with co-routines to write networking severs efficiently. As stated on the website, Diesel's core is a tight event loop that uses epoll to deliver nearly flat performance out to 10,000 connections and beyond. Here, we introduce Diesel with a simple echo server. You also need Diesel library 3.0 or any later version. You can do that with pip command:

 $ pip install diesel

If you encounter some issues in installing, make sure you have the dependencies installed. The following command should fix most of these errors:

$ sudo apt-get install build-essential...
