How to force web.py to single thread

[Helend]

Hi,

I am writing a simple web server to handle thousands of request in minute. But I have to make sure every request is completed before processing of a next request.

The server is build with Xampp 1.7.7 (Apache 2.2.21, MySQL 5.5.16). mod_wsgi 3.3, python 2.6, web.py 0.36, window 2008 x64

Are there any ways to it?

Thanks you in advance.

Use gunicorn with single process.

I had issues with disk based sessions on apache - turns out it was in part because of the threading.

I solved the session issue a different way, but these settings did help, and may guide you into getting apache into single thread mode.

(It was the "processes=1" setting that helped me.  Maybe this will help you too?)

<VirtualHost *:80>
    WSGIScriptAlias / /opt/myapp/web/main.py/
    WSGIDaemonProcess main processes=1 threads=25
    WSGIProcessGroup main
    Alias /static /opt/myapp/web/static/
    <Directory /opt/myapp/web/>
        Order allow,deny
        Allow from all
    </Directory>
</VirtualHost>

Thanks Anand and NSC,

Your methods are only working for linux, not for windows,

I am looking at these pages: http://code.google.com/p/modwsgi/wiki/ProcessesAndThreading and http://pylonsbook.com/en/1.1/the-web-server-gateway-interface-wsgi.html.

It seems this is the only way through changing WSGI environment variables.

Do anyone know how to change environment variable in web.py?

Thanks very much.
