Python Community in Anguish, Pain, Despair Over Web Server. First they had the guts to punk TechCrunch, now Facebook picks a fight with the Python community by releasing a web server, called Tornado, developed by recently acquired Friendfeed.
Terry Jones, CEO of Fluidinfo, probably best expressed the pain felt by Pythonistas: "Words fail me on this one. I’ve spent some hours today trying to put my thoughts into order so I could put together a reasonably coherent blog post on the subject. But I’ve failed. " Facebook's Bret Taylor explains the reasons for such a highly unpopular move: "We ended up writing our own web server and framework after looking at existing servers and tools like Twisted because none matched both our performance requirements and our ease-of-use requirements.
" The performance myth was quickly dismissed by an article which shows that Twisted performs almost as well as Tornado. Pwpwp looked at the Twisted documentation, to dispel the ease-of-use myth. As you can see clearly, it's mostly a problem of perception. What I Wish Tornado Were. FriendFeed has released its web server, Tornado. It seems like everyone's blogging about it, and it's obviously relevant to my interests, so I feel like I should say something. Let me start with the good stuff. First of all, I think it's great that we have yet another asynchronous contender in the Python world. Every time something like this comes out, it means that Twisted has to fight that much less hard to get over the huge hump of event-driven programming being too hard, or too weird, or whatever. It's good to have an endorsement of the general message "if you need a web server to handle COMET requests, it needs to be asynchronous to perform acceptably" from such a high-profile company as Facebook.
Unfortunately I think the larger picture here is a failure of communication in the open source community. This is especially important if you are later going to make claims about that project not living up to your vaguely-described requirements, and thereby damage its reputation. Tornado Web Server. Tornado is a Python web framework and asynchronous networking library, originally developed at FriendFeed. By using non-blocking network I/O, Tornado can scale to tens of thousands of open connections, making it ideal for long polling, WebSockets, and other applications that require a long-lived connection to each user.
Upgrade notes As of Tornado 3.2, the backports.ssl_match_hostname package must be installed when running Tornado on Python 2. This will be installed automatically when using pip or easy_install. Hello, world Here is a simple “Hello, world” example web app for Tornado: import tornado.ioloop import tornado.web class MainHandler(tornado.web.RequestHandler): def get(self): self.write("Hello, world") application = tornado.web.Application([ (r"/", MainHandler), ]) if __name__ == "__main__": application.listen(8888) tornado.ioloop.IOLoop.instance().start() This example does not use any of Tornado’s asynchronous features; for that see this simple chat room.
