Gunicorn ‘Green Unicorn’ is a Python WSGI HTTP Server for UNIX. It’s a pre-fork worker model ported from Ruby’s Unicorn project. The Gunicorn server is broadly compatible with various web frameworks, simply implemented, light on server resources, and fairly speedy.

What is a "pre-fork worker model"? I hear that term get thrown around, but I'm not sure what it means.

The Apache documentation has a nice overview:

http://httpd.apache.org/docs/2.2/mod/prefork.html

essentially it forks before a request comes in, the master process pushes requests to an idle "pre-forked" worker process. Works pretty well under Linux with pretty light processes - pretty badly under windows nt where processes are much fatter than threads.

The main process tries to maintain a pool of idle workers so there is no need to wait for a fork before an incomming request is handled.

One "master" process that keeps a pool of worker processes created by forking itself.

I was going to post this. It might be an idea to write what the project is in the post considering changelogs are generally not good and most people won't have heard of it

Changelog: 0.17.0 / 2012-12-25

    - allows gunicorn to bind to multiple address
    - add SSL support
    - add syslog support
    - add nworkers_changed hook
    - add response arg for post_request hook
    - parse command line with argparse (replace deprecated optparse)
    - fix PWD detection in arbiter
    - miscellenaeous PEP8 fixes

SSL support is probably the big ticket item here but I imagine most people already have an SSL termination solution already.

Doesn't look like anything I'd need so no upgrade I guess. Although the syslog support might be useful.

edit: double checked the previous changelogs and the settings detection change might be useful. On another note, the removal of python2.5 so soon is welcome.

Anyone know how the Python 3 support is coming along?
