Latest cherrypy from easy_install, virtualenv, and python 2.5.4 on redhat.

I am not a very experienced python or cherrypy developer, so I probably do not provide all necessary infos here. Yust drop me a line and I could provide anything needed...

Any ideas?

How did you start the process? Did you happen to (1) start it in a
terminal, not redirecting stdout and stderr, then (2) close the
terminal? This is what it looks like, from a curosry glance.

Some error is throwing the exception, but it then fails when trying to write that exception to stderr. This is because of the fork(), and the child process trying to reference a file descriptor to which it no longer has access.

It looks like you're not controlling stdin, stdout, and stderr for the child process. Take a look at this recipe:

http://code.activestate.com/recipes/66012/

and this will give you some ideas re: good practices for daemonizing your processes.

To find out what the _real_ error was, try running this on the command line:
/home/jan/webapps/www_limpens_com/bin/python2.5 /home/jan/webapps/www_limpens_com/site.py

It may be easier to debug this way, and daemonize when it's running well. All errors will appear in your terminal window in this case.

but no effect here...

no it is started via a autostart.cgi that looks like this:

#!/bin/env python2.4
import os

# Test if the process is already running
running = False
try:
    # Try to read pid file
    pid = open('/home/jan/webapps/www_limpens_com/pid').read()
    # Check if this process is up
    lines = os.popen('ps -p %s' % pid).readlines()
    if len(lines) > 1:
        running = True
    else:
        # Delete pid file
        os.remove('/home/jan/webapps/www_limpens_com/pid')
except IOError:
    pass

print "Content-type: text/html\r\n"
if running:
    print """<html><head><META HTTP-EQUIV="Refresh" CONTENT="2; URL=."></head><body>
    Site is starting ...<a href=".">click here<a></body></html>"""
else:
    print """<html><head><META HTTP-EQUIV="Refresh" CONTENT="2; URL=."></head><body>
    Restarting site ...<a href=".">click here<a></body></html>"""
    os.setpgid(os.getpid(), 0)

    pid = os.fork()
    if pid == 0:
        os.execl('/home/jan/webapps/www_limpens_com/bin/python2.5', '/home/jan/webapps/www_limpens_com/bin/python2.5', '/home/jan/webapps/www_limpens_com/site.py')
    else:
        open('/home/jan/webapps/www_limpens_com/pid', 'w').write(str(pid))

How did you start the process? Did you happen to (1) start it in a
terminal, not redirecting stdout and stderr, then (2) close the
terminal? This is what it looks like, from a curosry glance.

looks like you're running on webfaction and if recall correctly, the
default setup is mod_py. you app looks like it's using wsgi. did you
install wsgi 2.5 as a separate application? you got make sure you have
your app server.socket.port pointing to the port of the wsgi app

[Jan Limpens]

you are right, this is webfaction.
i did not install wsgi separately, but I setup the app as an "application listining to a port",
installed virtualenv ans setuptools, and in the env cherrypy, genshi and another lib. in the cherrypy config dict I pointet the app port to the port I was assigned and use 127.0.0.1 as host...

       'log.screen': False,
        'log.error_file': 'site.log',
        'server.socket_host': '127.0.0.1',
        'server.socket_port': 47405,
 
something I could do?
