404 test handler for rust https://github.com/rust-lang/rust/issues/18498

server.py

import sys
import BaseHTTPServer
from SimpleHTTPServer import SimpleHTTPRequestHandler


class HandlerClass(SimpleHTTPRequestHandler):
    def do_GET(self):
        SimpleHTTPRequestHandler.do_GET(self)
        with open("not_found.html") as f:
            HandlerClass.error_message_format = f.read()



ServerClass  = BaseHTTPServer.HTTPServer
Protocol     = "HTTP/1.0"

server_address = ('', 8080)

HandlerClass.protocol_version = Protocol
httpd = ServerClass(server_address, HandlerClass)

sa = httpd.socket.getsockname()
httpd.serve_forever()

I am sure there is a better way to set a 404 handler in a debug server, if there is, let me know.
