WSGI Mongrel2 Handler Status

Hi,

What is the status of a WSGI handler for Mongrel2 or where might I
look for information about writing one?  Should it be a 0mq handler or
HTTP?  Am I right in thinking that mongrel2 can handle all of the
supported communication methods and have mongrel2 route the traffic
over 0mq to a WSGI handler?  If so, this appears to be a very nice
direction to go.

Regards,

Jeff Van Voorst

AFAIK there are two actively maintained project:

http://wsgid.com/
http://projects.unbit.it/uwsgi/wiki/Mongrel2

Even if i am the maintainer of the uWSGI project, i like wsgid approach a
lot, and i suggest you to start with that one.

Hello,

I maintain wsgid and have been using it to host my own websites (my
personal and wsgid.com) for a while now.

Wsgid is reaching 0.5.0 very soon and I just added support for
mongrel2's async upload mechanism. With this release wsgid will
start to find its way into a production-ready tool.

Jeffrey, it would be awesome if you could try wsgid, and if you have
any problems it will be a pleasure to help.

Roberto, thank you for pointing wsgid!

Thanks to all and Happy new Year!

Thanks for your helpful replies.  By the way, I have looked at uwsgi.
I am more looking towards the future where I replace apache2 with
something that routes messages to a controller application which then
calls different backends which are primarily written in C++ and Python
at this time.  I was asking about a wsgi handler so that I could play
with hosting existing python frameworks via mongrel2 (I will check out
the recommendations and see how they work).  Maybe it is obvious to
others, but I didn't see an easy way to hook up C or C++ handlers to
uwsgi.

maybe not, but uWSGI can also talk 0MQ as a mongrel handler while
running Python WSGI apps.

uWSGI is a c app and all of the supported languages are hooked in with
(obviously) C.

Check this one:

http://projects.unbit.it/uwsgi/browser/plugins/example/example_plugin.c

or one of the other plugins:

http://projects.unbit.it/uwsgi/browser/plugins/

There is an example on hooking C++ too

http://projects.unbit.it/uwsgi/browser/plugins/cplusplus/base.cc

WSGI is not the kind of thing that needs lots of maintenance. I would
checkout Ryan Kelly's m2wsgi or even the Brubeck project (of which I am a
dev) and avoid using WSGI altogether.
