I'm pleased to announce the release of the WSGI module for nginx, version 0.0.6.

The WSGI module is an implementation of the Python Web Server Gateway Interface v1.0 (http://python.org/dev/peps/pep-0333/) for the Nginx server.

The module is available only via a Mercurial repository at: http://hg.mperillo.ath.cx/nginx/mod_wsgi/

Here is a changelog:

- Bug fix: configuration problem on Mac OS X.

- Added support for nginx 0.5.34, and dropped support for older versions.

Note: older version are only supported via patches. - Added wsgi_optimize_send_headers directive.

WSGI spec requires that the headers must be sent when the first not empty string is yielded, however sending headers early can optimize content generation.

- Added experimental support for interpreter finalization.

This will ensure that sys.exitfunc is called. - Variables declared with wsgi_var directive can override HTTP_ variables.

It can be useful, as an example, to override HTTP_COOKIE with:

wsgi_var HTTP_COOKIE $http_cookie;

since the $http_cookie variable combines multiple Cookie headers. - Renamed the wsgi_params directive to wsgi_var.

wsgi_param was a poor choice, since parameters are a concept used by FastCGI.

This revision breaks compatibility. - Added the wsgi_allow_ranges directive, for integrated support to partial HTTP requests. - Added the ngx_wsgitest.py script, that executes a WSGI application in a testing environment. - Added the ngx_wsgiref.py script, that runs a WSGI application using the builtin wsgiref server, with a command line compatibile with ngx_wsgi.py. - Added the ngx_wsgi.py script, for rapid deployment of WSGI applications using nginx and mod_wsgi. - Added wsgi_middleware directive.

This directive enables middleware stacking in mod_wsgi. - Removed the callable_object and the wsgi_alias directives, and added a new wsgi_pass directive.

The new directive is more consistent with other nginx modules like mod_fastcgi and mod_proxy.

This revision breaks compatibility.
