How to do Tornado HTTPServer with bind_unix_sock?

Question

I've got a simple server. It works if I do a normal socket, but if I try to use a unix socket, I don't think it's working.

Here is the server:

from tornado.httpserver import HTTPServer
import tornado.ioloop
from tornado.netutil import bind_unix_socket
import tornado.web

class MainHandler(tornado.web.RequestHandler):
    def get(self):
        self.write("Hello, world")

application = tornado.web.Application([
    (r"/", MainHandler),
])

if __name__ == "__main__":
    server = HTTPServer(application)
    unix_socket = bind_unix_socket('/tmp/foo.sock')
    server.add_socket(unix_socket)
    tornado.ioloop.IOLoop.instance().start()

Here is how I'm testing:

~  socat - UNIX-CONNECT:/tmp/foo.sock
GET / HTTP/1.1
HOST: foobar.com
*hit enter a few times to complete http call*

The server doesn't give any response.

Any idea what I'm doing wrong?

You're sending \n instead of \r\n. You can use socat's "crnl" option to make it work more like telnet:

socat - unix-connect:/tmp/foo.sock,crnl

this command is not giving any output (idle) with the above (OP) server. Can you please help in saying what is happening. I am using Python3.5.2 with tornado==5.1.1 on ubuntu 16.04. – Ram Idavalapati Jan 10 '19 at 12:04
