Mailman 3 Re: [Twisted-Python] twisted.web.server and memory - Twisted

14 Mar 2005


      Run the following web server (memoryhogserver.py) and
load the provided form (post.html) into a browser of
your choice and choose a large file (~100MB) to
submit.  Notice the memory usage of the python process
(on my machine, around 150MB resident).

memoryhogserver.py:

from twisted.web.resource import Resource
from twisted.web import server, resource
from twisted.internet import reactor
import os
                                                      
                         
class ROOT(Resource):
    def __init__(self):
        Resource.__init__(self)
                                                      
                         
    def getChild(self, name, request):
        if name == "":
            return self
        return Resource.getChild(self, name, request)
                                                      
                         
    def render_GET(self, request):
        return "<html>root dir</hrml>"
                                                      
                         
class UPLOAD(ROOT):
    def render_POST(self, request):
        f = open("/tmp/testfile","wb")
        f.write(request.args.get('filename')[0])
        f.close()
        return "<html>upload successful</html>"
    def render_GET(self, request):
        return "'upload' must use POST"
                                                      
                         
if __name__ == '__main__':
    root = ROOT()
    root.putChild('upload',UPLOAD())
    site = server.Site(root)
    reactor.listenTCP(7000, site)
    print "webserver listening on port 7000"
    reactor.run()


post.html:

<html>
    <form method="POST" enctype="multipart/form-data"
action="http://localhost:7000/upload">
        <input type="file" name="filename">
        <input type="submit">
    </form>
</html>

If a code snippet that reproduces the above would
help, I'd be happy to produce one.
