#47142 — Errin when executing a cgi script that sets a cookie in the browser

Since the other thread gone into the wild, i choosed not to participate any longer and i state the question in this new thread.

'python files.py' interprets without an error.
Problem is that when via browser - http://superhost.gr/cgi-bin/koukos.py
i receive the following:

-------------------------------
root@nikos [/home/nikos/www/cgi-bin]# ls
./  ../  convert.py*  files.py*  .htaccess  koukos.py*  metrites.py*  pelatologio.py*

root@nikos [/home/nikos/www/cgi-bin]# tail -F /usr/local/apache/logs/error_log &

----------------------------------

What file does the error complain it cannot find? I do not understand its message. Here is the code of koukos.py


-----------------------------
#!/usr/bin/python
# coding=utf-8

import cgitb; cgitb.enable()
import cgi, os, sys, locale, codecs
from http import cookies

#needed line, script does *not* work without it
sys.stdout = codecs.getwriter('utf-8')(sys.stdout.detach())

# initialize cookie
cookie = cookies.SimpleCookie( os.environ.get('HTTP_COOKIE') )
cookie.load( cookie )
nikos = cookie.get('nikos')

# if visitor cookie does exist
if nikos:
	message = "ΑΠΟ ΤΗΝ ΕΠΟΜΕΝΗ ΕΠΙΣΚΕΨΗ ΣΟΥ ΘΑ ΣΕ ΥΠΟΛΟΓΙΖΩ ΩΣ ΕΠΙΣΚΕΠΤΗ ΑΥΞΑΝΟΝΤΑΣ ΤΟΝ ΜΕΤΡΗΤΗ!"
	cookie['nikos'] = 'admin'
	cookie['nikos']['path'] = '/'
	cookie['nikos']['expires'] = -1		#this cookie will expire now
else:
	message  = "ΑΠΟ ΔΩ ΚΑΙ ΣΤΟ ΕΞΗΣ ΔΕΝ ΣΕ ΕΙΔΑ, ΔΕΝ ΣΕ ΞΕΡΩ, ΔΕΝ ΣΕ ΑΚΟΥΣΑ! ΘΑ ΕΙΣΑΙ ΠΛΕΟΝ Ο ΑΟΡΑΤΟΣ ΕΠΙΣΚΕΠΤΗΣ!!"
	cookie['nikos'] = 'admin'
	cookie['nikos']['path'] = '/'
	cookie['nikos']['expires'] = 60*60*24*30*12		#this cookie will expire in a year


print( cookie, "Content-type: text/html; charset=utf-8\n", message )

sys.exit(0)
---------------------------------

All it tries to do is to set a cookie.

Does /usr/bin/python exist?  Scripts can throw a 'No such file or directory'
or 'Command not found' error if they begin with a shebang line which refers
to a nonexistent program.

Do you know what this does?

Try it at the console. See what it outputs.

If you look in the Apache error log file, you will see something like,

  [Wed Jun 05 16:39:14 2013] [error] [client 192.168.0.1] malformed header from script. Bad header= \xce\x91\xce\xa0\xce\x9f \xce\x94\xce\xa9 \xce\x9a\xce\x91\xce\x99 \xce\xa3\xce\xa4\xce\x9f \xce\x95\xce: koukos.py

which is saying that the 'message' text is being interpreted as 
being part of the headers.

You are missing a blank line between the header lines and the 
page text.  That is, I think you want, 

  print( cookie, "Content-type: text/html; charset=utf-8\n\n", message )

(ie, note the two \n's after the "utf-8" test.)

But that won't solve it either. The default separator for print is a
space, so this will indent his Content-type line by one space. Nikos,
do you know what effect that will have? If not, research HTTP. RFC
2616 is a good place to start.

Ah, quite right.  Something like 

  print( cookie, "\nContent-type: text/html; charset=utf-8\n\n", message )

then.

Or change the sep, or concatenate with + instead of using , between
them. Or put them on separate lines. Anything like that would work.
And it's really easy to try things out interactively to see what
they'll do...

Of course.

Sure, once one makes the connection between "Server Error" and missing "\n"
which is where Νικόλαος was stuck I'm guessing.

I know that's a bit of a jump. That's why, right back when he first
posted his problem, I quoted _that one line_ and pointed him to the
interactive interpreter. I'm pretty sure he still isn't reading my
posts... or, most likely, anyone's.

| Ah, quite right.  Something like 
| 
|   print( cookie, "\nContent-type: text/html; charset=utf-8\n\n", message )
| 
| then.

Unless "cookie" already has a newline. Then you'll end the headers there:-)

A more robust approach might be to build a dict (or possibly better,
list) of headers without newlines and then as a separate act to
print them with newlines and add the spacer newline later, before
writing the message body.

print( cookie, "\nContent-type: text/html; charset=utf-8\n\n", message )

or by trying:

print( cookie + "\nContent-type: text/html; charset=utf-8\n\n" + message )

the output is for both:

nikos@superhost.gr [~]# tail -F /usr/local/apache/logs/error_log &

nikos@superhost.gr [~]# [Thu Jun 06 06:20:11 2013] [error] [client 79.103.41.173] (2)No such file or directory: exec of '/home/nikos/public_html/cgi-bin/koukos.py' failed

I have re-enabled 'suexec' and set cgi as default phphandler and then trying:

print( cookie )
print( '''Content-type: text/html; charset=utf-8\n''' )
print( message )

---------------------------------

Even if dissable/enable suexec still this output error.

This is only a guess but...

The permissions on koukos.py have to be exactly right.
Obviously if they are too restrictive Apache won't be
able to read or execute it.  But they can't be to open 
either -- in particular the file must have execute
permission and must not have write permission for either
group or others (write for user only).

If the permissions are too open, Apache will try to write 
an error message to suexec.log.  I suspect that your 
permissions (or file owner) is wrong on your suexec.log 
file (or containing directory) and that is the cause of 
the "could not open log file " message.

So I think you have too problems: wrong permissions on
koukos.py and wrong owner or permissions on suexec.log.

For reference this is working here:
 -rw-r--r-- 1 apache apache 314 Jun  6 12:19 /var/log/httpd/suexec.log

 -rwxr-xr-x 1 me me 1113 Jun  5 14:40 koukos.py

You'll need to adjust things for your particular Apache 
environment.

As I said, this is only a guess.  Hope it helps.

Hello! thanks for trying to help.
Here they are:

nikos@superhost.gr [~/www/cgi-bin]# ls -l koukos.py
-rwxr-xr-x 1 nikos nikos 1160 Jun  6 06:27 koukos.py*

nikos@superhost.gr [~/www/cgi-bin]# ls -l /var/log/httpd/suexec.log
-rw-rw-rw- 1 root apache 0 Jun  1 02:52 /var/log/httpd/suexec.log

nikos@superhost.gr [~/www/cgi-bin]# ls -l /usr/local/apache/logs/suexec_log
-rw-rw-r-- 1 root apache 675097 Jun  6 21:43 /usr/local/apache/logs/suexec_log


I have applied to them the group 'apache' so Apache User can utilize them.

But its still a wonder to me why two different suexec logs exist.
Please tell me wht else you want me to try.

Since cPanel is in charge of apache i ahve even:

chown nobody:nobody to both of the suexec logs.

nikos@superhost.gr [~/www/cgi-bin]# ls -l /usr/local/apache/logs/suexec_log
-rw-rw-r-- 1 nobody nobody 675389 Jun  6 22:05 /usr/local/apache/logs/suexec_log
nikos@superhost.gr [~/www/cgi-bin]# ls -l /var/log/httpd/su*
-rw-rw-rw- 1 nobody nobody 0 Jun  1 02:52 /var/log/httpd/suexec_log


Still same error :(

Did you tried running that by a standalone Python interpreter? Did you
notice something strange, something like that an empty line is missing
between headers and body?

No, nothing at all.
Two '/n/n' are not required. Months now the way i'm printing headers is by:

print( '''Content-type: text/html; charset=utf-8\n''' ) 

and the scripts owrk correctly in browser and in python interpreter too.

He will get an extra blank line, since he added a newline character at
the end of his Content-Type string.

Skip
