cherryd/fastcgi/lighttpd
Eric Abrahamsen
FCGI servers via flup. I've been working with the regular lighttpd
configuration that uses a script file. Since httpd starts a process of
its own, is it possible to use it in conjunction with another
webserver like lighttpd? I've tried connecting via a socket file,
rather than host/port combination, but it seems to want to use host/
port even with server.socket_file set. Can this be done, or am I
barking up the wrong tree?
Thanks,
Eric

I'm sure it can, it'll just take a little glue. Try modifying cherryd as
follows:
sock_file = cherrypy.config.get('server.socket_file', None)
if sock_file:
bindAddress = sock_file
else:
fastcgi_port = cherrypy.config.get('server.socket_port', 4000)
fastcgi_bindaddr = cherrypy.config.get('server.socket_host',
'0.0.0.0')
bindAddress = (fastcgi_bindaddr, fastcgi_port)
Whether that works or not, please open a ticket. :)

I tried with that, and the engine got as far as starting the monitor
threads before it blew up like so:
ENGINE Error in HTTP server: shutting down

I'm testing this with a barebones "hello world" setup. Lighttpd is not
running at this point, not sure if that makes any difference.
python cherryd -c site.conf -f

georgem has been doing some great work on getting this going--please try
out trunk and let us know how it goes.

Starts beautifully. I'll try it with the full lighttpd stack when I
have a little more time, but I don't see why that wouldn't work.
Thanks a lot to georgem et al. for all the work! Cherrypy continues to
rock.

since (very weird, since nothing in my environment has changed, so far
as I can tell). The next few times I tried it it died with the
following error:
File "/home/taojian/lib/python2.5/cherrypy/process/servers.py",
line 95, in wait
raise self.interrupt
error: (95, 'Operation not supported')
The last time it died with that error, twice, and then got into an
infinite loop between wspbus.py:315 and wspbus.py:157, log and
publish, back and forth. I'm pasting everything below; the log/publish
loop continued until it hit max recursion depth...
Sorry to be a spoilsport,
Eric

OK, first things first. http://www.cherrypy.org/changeset/2027 should
fix the infinite loop.

Why is wsgiserver being run? That should be unsubscribed when you choose
FastCGI (via the '-f' arg to cherryd).

stack. Updating the CP code indeed fixed the infinite loop, and
remembering to use the -f option to cherryd (ahem), fixed the other
problem. :)
Thanks again!
