[2.4.3/Newbie] Web script doesn't run
Hello
I have a couple of newbie questions about using Python in a FastCGI
+ Flup context on a shared CentOS server:
1. The following script runs fine...
=
#!/usr/bin/env python2.6
def myapp(environ, start_response):
start_response('200 OK', [('Content-Type', 'text/plain')])
return ['Done!\n']
if __name__ == '__main__':
from flup.server.fcgi import WSGIServer
WSGIServer(myapp).run()
=
... while this triggers an error:
=
#!/usr/bin/env python2.6
# -*- coding: UTF-8 -*-
from cgi import escape
import sys, os
def app(environ, start_response):
start_response('200 OK', [('Content-Type', 'text/html')])
yield 'h1FastCGI Environment/h1'
yield 'table'
for k, v in sorted(environ.items()):
yield 'trth%s/thtd%s/td/tr' % (escape(k),
escape(v))
yield '/table'
if __name__ == '__main__':
from flup.server.fcgi import WSGIServer
WSGIServer(app).run()
=
Internal Server Error: The server encountered an internal error or
misconfiguration and was unable to complete your request. [...]
Additionally, a 404 Not Found error was encountered while trying to
use an ErrorDocument to handle the request.
2. Generally speaking, what is the right way to investigate an error
in a Python web script? FWIW I have access to the shared server
through SSH.
Thank you.

You may also want to consider looking for your server's error log - that may be getting the actual traceback. I don't know what your server setup is, but there's likely to be one somewhere. A question though. You say 2.4.3 in your subject line, but your shebang says python2.6 - which version are you actually running? At very least, I'd recommend using python2.6 to run your script from the shell; if there's any incompatibility between the system Python (which quite plausibly would be the 2.4.3 you named) and the one your CGI script uses (named python2.6 and my guess would be that it's 2.6.6), you'll confuse yourself when you do your shell test.

Good to know. A question though. You say 2.4.3 in your subject line, but your shebang says python2.6 - which version are you actually running? I didn't pay attention to this. Support says that I should use 2.6, but running python -V through SSH says 2.4.3. I'll ask support which to use. Thank you. -- http://mail.python.org/mailman/listinfo/python-list

Try running python2.6 -V Your shebang line says that it's looking for a program named python2.6, which is quite probably not the same as the one named just python.

Indeed, they have two versions of Python installed: # python2.6 -V Python 2.6.4 # python -V Python 2.4.3 I'll make sure to use 2.6. Thank you. -- http://mail.python.org/mailman/listinfo/python-list

Different Pythons coexist quite happily on a system. Anyway, seems your issue's sorted out. Yay! ChrisA -- http://mail.python.org/mailman/listinfo/python-list

Thank for the help. I'm on my way to figure out how mod_fcgid, Flup, and Python scripts work together. -- http://mail.python.org/mailman/listinfo/python-list
