GoogleCodeExporter commented 8 years ago 
发现OJ题目中很多题目都PE，原来是最后一行的\n的问题。
记得原来的HUSTOJ 
CORE是有几条语句处理这个的，即忽略最后有没有\n。
所以建议在所用的ZOJ的那部分评测代码后面也加上这样的机��
�。
毕竟因为最后一个换行总让人PE很不爽...

try r504 to see if it got your point

GoogleCodeExporter commented 8 years ago 
I tried, it doesn't work, remained PE.
But when I switched to the original HUSTOJ core, everything became okay. 
I think you still have to fix this in ZOJ core (compare function), in another 
way...

try r508 ?

Original comment by newsc...@gmail.com on 10 Nov 2010 at 2:38

GoogleCodeExporter commented 8 years ago 
r508 still didn't work, it can't forgive the last '\n' either.

http://acm.sie.edu.cn/JudgeOnline/showsource.php?id=940

i've added
   printf("\n\n\n");
 before return 0;

it AC.

Yes, you ACed because I switched to the original HUSTOJ comparition function...

When I use the ZOJ compare(), many problems PE...

i AC too.

have you did what i recommanded in issue27 ?

Original comment by newsc...@gmail.com on 11 Nov 2010 at 9:06

GoogleCodeExporter commented 8 years ago 
i mean

{{{
cd /home/judge/data
find . -name *.in -exec fromdos -d {} \;
find . -name *.out -exec fromdos -d {} \;
}}}

No '\r\n' in those files...

Original comment by cn-...@china.com.cn on 11 Nov 2010 at 9:18

GoogleCodeExporter commented 8 years ago 
I saw there's a function 
{{{
void delnextline(char s[]) {
    int L;
    L = strlen(s);
    while (L > 0 && (s[L - 1] == '\n' || s[L - 1] == '\r'))
        s[--L] = 0;
}
}}}
in the original HUST judge_client which can ignore all the \r or \n characters.

GoogleCodeExporter commented 8 years ago 
But all in all, I think since 

#define STD_MB 1048576 //10M Byte, I think
#define STD_F_LIM (STD_MB<<5)

so the limit output file size in HUSTOJ judge_client can reach 32MB, it's 
enough for any type of contests.

the r504 is ignore all space character

the memory alloc and free operation slow down the judger and there is some data 
bigger than 32m in my system

Original comment by newsc...@gmail.com on 11 Nov 2010 at 9:38

GoogleCodeExporter commented 8 years ago 
But I tested, even the ZOJ_compare you modified could not ignore the '\n' 
characters (at least the last one), while the original HUSTOJ_compare can.

just try to make a PE for this 
http://www.newsclan.com/JudgeOnline/problem.php?id=1104
then i could find out what's really wrong.

GoogleCodeExporter commented 8 years ago 
maybe you can upload your data file themselves here,not just FPS.
FPS export function can fix \r\n problem.

Those are test data files of this problem in our OJ
