pyc runtime error
Can anyone explain this unexpected behavior? all files chmod 755, i've compiled x.py with py_compilefiles, also tried within python console with import x system: centos 5.4 32bit This a PATH related problem i think? [r...@centos-14 cgi-bin]# ./x.pyc : command not found ./x.pyc: line 2: syntax error near unexpected token `)' ./x.pyc: line 2: `��)l...@s dghdghdkzeighds(sContent-Type:text/ html' [r...@centos-14 cgi-bin]# python x.pyc Content-Type:text/html python 2.4.3 (#1, Sep 3 2009, 15:37:12) [GCC 4.1.2 20080704 (Red Hat 4.1.2-46)] x.py file content: #!/usr/bin/env python print Content-Type:text/html\n\n print python import sys print sys.version -- http://mail.python.org/mailman/listinfo/python-list

I'm sorry -- can you let us know what behavior you're expecting? all files chmod 755, i've compiled x.py with py_compilefiles, also tried within python console with import x system: centos 5.4 32bit This a PATH related problem i think? Perhaps I'm misunderstanding what you're trying to do but from what I can see, you are expecting .pyc files to be directly executed by the shell. And as I understand them, they are *not* meant to be directly executed by the shell at all -- they're simply a sometimes-useful shortcut for the Python interpreter. Python scripts like your x.py, however, *are* meant to be executed by the shell. Have you tried: [u...@box cgi-bin]$ ./x.py ? [r...@centos-14 cgi-bin]# ./x.pyc May I ask, as well, why you're doing all of this as root?

This machine is a local virtual test machine so security issues are omitted. Actually i wrote some scripts in python that are working as gateway controlling scripts iptables/tc/squid-proxy, and i want to execute them as cgi. Protection of source code is also important. These scripts works fine with ubuntu 9.10 and ubuntu 10.04, trying to eleminate this execution error and successfully port them to centos 5.4. Or i have to rewrite these scripts in C which is time comsuming. On centos 5.4, i think httpd tries to execute it as i did ./x.pyc. -- http://mail.python.org/mailman/listinfo/python-list

Do you have some Python related files in /proc/sys/fs/binfmt_misc/ ? Christian Thanks Christian, before your message i was thinking about writing wrapper to turn round this issue. my wrapper: #!/usr/bin/bash /usr/bin/python m_file.pyc Yes /proc/sys/fs/binfmt_misc/python2.6 is there. enabled interpreter /usr/bin/python2.6 flags: offset 0 magic d1f20d0a How can make it possible in centos? With custom kernel compiling? -- http://mail.python.org/mailman/listinfo/python-list

According to this documentation below, i've solved my problem. http://git.kernel.org/gitweb.cgi?p=linux/kernel/git/torvalds/linux-2.6.git;a=blob;f=Documentation/binfmt_misc.txt;hb=HEAD registered .pyc extension to invoke python interpreter. Done, thank you everybody, especially Christian.. -- http://mail.python.org/mailman/listinfo/python-list

With custom kernel compiling? The binfmt_misc module has to be loaded, which is presumably is, if /proc/sys/fs/binfmt_misc exists (not 100% sure on that) It's almost certainly provided by CentOS, even if it's not loaded by default. Assuming file.pyc was actually compiled by python2.6, and not some other version, it should work. -- Thomas Yes centos5.4 loads it automatically, however little kickstart script in /etc/rc.local is required. is_python=$(ls -l /proc/sys/fs/binfmt_misc/python2.4 | wc -l) if [ $is_python -lt 1 ]; then echo ':python2.4:E::pyc::/usr/bin/python:' /proc/sys/fs/binfmt_misc/ register fi i'm still digging in.. -- http://mail.python.org/mailman/listinfo/python-list
