The Django development server is great: it comes in the box, serves Django, auto-restarts on source code changes, and now even color-codes the log lines based on the status returns.
But it isn't multi-threaded, which normally wouldn't be a problem for a development server, unless you're writing Ajax interactions, and these days, who isn't?
The Django team has declared that they will not offer a multi-threaded development server, for good or bad, so we are left to our own devices. James Aylett wrote django_concurrent_test_server which offers multi-threading and forking, though I haven't tried it. David Cramer offers django-devserver which seems to offer a number of interesting new logging options also. Many developers simply use other "real" web servers, like Apache or gunicorn, but those don't detect code changes, and often don't provide stdout for debugging with.
I wanted multi-threading on a project but I didn't want to use a big real web server, and didn't want to install a new Django app and modify settings.py, so I adapted the patch from the closed Django bug ticket to create threadedmanage.py:
# A clone of manage.py, with multi-threadedness monkeypatched in.
import os, sys
from django.core.management import execute_manager
import settings # Assumed to be in the same directory.
"Error: Can't find the file 'settings.py' in the directory containing %r. "
"It appears you've customized things.\n"
"You'll have to run django-admin.py, passing it your settings module.\n"
"(If the file settings.py does indeed exist, it's causing an ImportError somehow.)\n"
# This monkey-patches BaseHTTPServer to create a base HTTPServer class that
# supports multithreading
import BaseHTTPServer, SocketServer
OriginalHTTPServer = BaseHTTPServer.HTTPServer
class ThreadedHTTPServer(SocketServer.ThreadingMixIn, OriginalHTTPServer):
def __init__(self, server_address, RequestHandlerClass=None):
OriginalHTTPServer.__init__(self, server_address, RequestHandlerClass)
BaseHTTPServer.HTTPServer = ThreadedHTTPServer
if __name__ == "__main__":
Now I can run "./threadedmanage.py runserver .." and get the standard development server, but with multiple threads.
The usual caveats apply: This isn't a real web server, don't use it in production. Your code likely has threading issues, please fix them. I'm pretty sure there are good reasons not to use this code, but it's working well for me.
