Processing Simultaneous/asynchronous Requests With Python Basehttpserver

I've set up a threaded (with Python threads) HTTP server by creating a class that inherits from HTTPServer and ThreadingMixIn: class ThreadedHTTPServer(ThreadingMixIn, HTTPServer):

Solution 1:

classThreadedHTTPServer(ThreadingMixIn, HTTPServer):
    pass

is enough. Your client probably don't make concurrent requests. If you make the requests in parallel the threaded server works as expected. Here's the client:

#!/usr/bin/env pythonimport sys
import urllib2

from threading import Thread

defmake_request(url):
    print urllib2.urlopen(url).read()

defmain():
    port = int(sys.argv[1]) iflen(sys.argv) > 1else8000for _ inrange(10):
        Thread(target=make_request, args=("http://localhost:%d" % port,)).start()

main()

And the corresponding server:

import time
from BaseHTTPServer   import BaseHTTPRequestHandler, HTTPServer, test as _test
from SocketServer     import ThreadingMixIn


classThreadedHTTPServer(ThreadingMixIn, HTTPServer):
    passclassSlowHandler(BaseHTTPRequestHandler):
    defdo_GET(self):
        self.send_response(200)
        self.send_header("Content-type", "text/plain")
        self.end_headers()

        self.wfile.write("Entered GET request handler")
        time.sleep(1)
        self.wfile.write("Sending response!")

deftest(HandlerClass = SlowHandler,
         ServerClass = ThreadedHTTPServer):
    _test(HandlerClass, ServerClass)


if __name__ == '__main__':
    test()

All 10 requests finish in 1 second. If you remove ThreadingMixIn from the server definition then all 10 requests take 10 seconds to complete.
