    <p>The following code (taken from here: <a href="https://bitbucket.org/denis/gevent/src/6c710e8ae58b/examples/wsgiserver_ssl.py" rel="nofollow">https://bitbucket.org/denis/gevent/src/6c710e8ae58b/examples/wsgiserver_ssl.py</a>) implements an extremely fast greenlet powered wsgi webserver:</p> <pre><code>#!/usr/bin/python """Secure WSGI server example based on gevent.pywsgi""" from gevent import pywsgi def hello_world(env, start_response): if env['PATH_INFO'] == '/': start_response('200 OK', [('Content-Type', 'text/html')]) return ["&lt;b&gt;hello world&lt;/b&gt;"] else: start_response('404 Not Found', [('Content-Type', 'text/html')]) return ['&lt;h1&gt;Not Found&lt;/h1&gt;'] print 'Serving on https://127.0.0.1:8443' server = pywsgi.WSGIServer(('0.0.0.0', 8443), hello_world, keyfile='server.key', certfile='server.crt') # to start the server asynchronously, call server.start() # we use blocking serve_forever() here because we have no other jobs server.serve_forever() </code></pre> <p>However, this only runs on one core. How would you modify this to take advantage of multiple processes? Not looking for an answer that involves gunicorn, looking for something simpler.</p> <p><strong>HINT</strong></p> <p>Here is a code sample using gevent and multiprocessing, but I still can't figure out how to make this work with WSGI (taken from <a href="https://gist.github.com/1169975" rel="nofollow">https://gist.github.com/1169975</a>):</p> <pre><code>import sys from gevent import server from gevent.baseserver import _tcp_listener from gevent.monkey import patch_all; patch_all() from multiprocessing import Process, current_process, cpu_count def note(format, *args): sys.stderr.write('[%s]\t%s\n' % (current_process().name, format%args)) def echo(socket, address): print 'New connection from %s:%s' % address fileobj = socket.makefile() fileobj.write('Welcome to the echo server! Type quit to exit.\r\n') fileobj.write('In %s\r\n' % current_process().name) fileobj.flush() while True: line = fileobj.readline() if not line: print "client disconnected" break if line.strip().lower() == 'quit': print "client quit" break fileobj.write(current_process().name + '\t' + line) fileobj.flush() print "echoed", repr(line) listener = _tcp_listener(('127.0.0.1', 8001)) def serve_forever(listener): note('starting server') server.StreamServer(listener, echo).serve_forever() number_of_processes = 5 print 'Starting %s processes' % number_of_processes for i in range(number_of_processes): Process(target=serve_forever, args=(listener,)).start() serve_forever(listener) </code></pre>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
