Python support about hustoj

[GoogleCodeExporter]

from judge_client.cc to web/status.php and others 
a lot of files need to be modify
i may do that later, but if you are in a hurry, try first update to the latest 
SVN version for Ruby and Bash support ,after that you can try to do that by 
refering to the ruby support code.

How can i add mono c# to this system ?
I read wiki section but i couldn't understand the settings of the 
judge_client.cc Please describe it a bit more.

1 you need a a+b program written in c#
2 you need to figure out which files is needed to run this program
3 using strace to collect all sys_calls needed by the program
4 edit judge_client.cc on all point listed in AddProgrammingLanguage

using root account to debug/step trace judge_client in codeblocks may help you 
on understanding the routine of judge_client.

if you have any questions , post it here with the code line number, i'll try to 
explain it or add comments to the code in svn.

click on rXXX and then click diff will show the code added/modified exactly.

the python language results wrong answer instead of compile error.
how can i solve this problem.

i wonder if python is a compilable language ?

hamidrezaabdi may want to detect syntax error in a submission file

You can check syntax of a python code following command line:
python -c "import py_compile,sys; sys.stderr=sys.stdout; 
py_compile.compile(r'Main.py')"

Does it works well? It doesn't works well in my server.

Here's debug message of the judge_client(r777):

what code in the solution was written?
what distribution and python version are you running?
you might need to add coe in okcalls.h for 64-bits system, because i don't have 
a 64 bits system to debug with, ruby bash python do not support 64-bits yet.

using strace to collect all sys_calls needed by the program
and add them into okcalls.h for 64bits
like:   callid:14
add to okcalls.h :
#ifdef __i386
....
#else
.....
int LANG_YV[256]={14,0};
int LANG_YC[256]={-1,0};
#endif

just follow AddProgrammingLanguage 
do the first two steps

ON A 64-bits system

I just applied the your method but It doesn't works.

I tried to find reason for the problem but I couldn't found resolution method.

anyway I just found size of user.out and error.out in runX directory were 0 
after judging process finished.

[GoogleCodeExporter]

would you like to post your 64-bits version of okcalls.h here?
especially the section:
#else
...
int LANG_YV[256]={...,0};
int LANG_YC[256]={...,0};
#endif

and run debug again
judge_client 57316 0 /home/judge 0
post the output too
