FastCGI Unhandled Exception

[cpghost@…]

Running /usr/ports/www/py-django-devel (Django-20070214.tar.gz) on FreeBSD 6.2, I can't get FastCGI (with lighttpd) to run. The embedded (runserver) server works correctly, just runfcgi doesn't.

How to reproduce:

---

1. Start lighttpd/fastcgi like this:

server.port                = 85
fastcgi.server             = ( "/" =>
                               ( "localhost" =>
                                 (
                                   "host" => "127.0.0.1",
                                   "port" => 10002,
                                   "bin-copy-environment" =>
                                   (
                                     "PATH", "SHELL", "USER"
                                   ),
                                   "broken-scriptfilename" => "enable",
                                 )
                               )
                            )

2. django-admin.py startproject mysite

3. cd mysite

4. python manage.py runfcgi method=threaded host=127.0.0.1 port=10002 daemonize=True

Now access ​http://127.0.0.1:85/ (Unhandled Exception - instead of the Django greeting page),
and ​http://127.0.0.1:85/blah (404, as expected).

Adding a view and mapping it with urls.py also results in 404.

Everything works just fine with runserver, but not with runfcgi. Same problem with 0.95. Same problem with prefork instead of threaded.

By applying the following patch to /usr/local/lib/python2.5/site-packages/django/core/servers/fastcgi.py:

and accessing ​http://127.0.0.1:85/, I get a long stack trace which ends like this:

Another data point: lighttpd's error log:

Ups, sorry, previous error log was with Django 0.95. Same with devel version:
