How to configure lighttpd bin-path parameter with flup/python

I am running lighttpd 1.4.26 on Ubuntu 10.04 with Flup 1.0.3 dev version.

When setting up mod_fastcgi, I can successfully get lighttpd to communicate with the fcgi process on a local socket if I spin up the fcgi manually (as www-data) prior to starting lighttpd. 

sudo su www-data
/webapps/test/test.fcgi

then in another shell...

sudo /etc/init.d/lighttpd/start

When I try to use the bin-path parameter in the fastcgi.server config to start this process automatically, the process starts, but does not successfully communicate with the process.

I have isolated the messages in the lighttpd\error.log to the following:

Successful (manual start):

My fastcgi config:

server.modules   += ( "mod_fastcgi" )

## Start an FastCGI server
fastcgi.debug = 1

fastcgi.server    = ( ".fcgi" =>
                      ( "localhost" =>
                        (
                        "socket" => "/tmp/fcgi.sock",
                        #"bin-path" => "/webapps/test/test.fcgi",
                        "max-procs" => 1,
                        "check-local" => "disable"
                                        )
                                      )
                                )

The only change I am making is to uncomment the bin-path line to reference the fcgi file directly.

The contents of the fcgi file are just a simple hello world:

#!/usr/bin/python2.6

from flup.server.fcgi import WSGIServer

def myapp(environ, start_response):
    print 'got request: %s' % environ
    start_response('200 OK', [('Content-Type', 'text/plain')])
    return ['Hello World!\n']

WSGIServer(myapp, bindAddress = '/tmp/fcgi.sock').run()

I am new to lighttpd, so perhaps I am missing something simple. Thanks in advance!

I had the same issue in my installation of lighttpd and Django with flup. Resolved it by setting up flup for socket file xxx.sock-0 instead of xxx.sock as before. It may work for you too.

It looks a bit hacky. I am not a Linux guru, may be somebody else will respond with a solution.
