Problems in using third party libraries

单独调用评测机的接口时，想要评测一些加了第三方库的代码时出现问题。请问如何在评测机中完成第三方库的调用？

文档地址挂了吗？

https://docs.onlinejudge.me/

运行client里的client.py报错“failed to create runtime dir”

为什么不把JudgeServer的input,output弄成json传值

我看了下文档，现在judger判卷是根据本地的.in, .out 文件，为什么不做成json传递的。像HackerRank那样的api，这样我们更加容易自己开发，也可以参考下另一个开源项目Judge0

关于评测队列

请问当多个用户同时提交代码时评测机会怎么处理？同时评测多个还是一次一个，前一个结束之后再测下一个？

judger返回result为4，但exit_code为0

而且output验证了也是正确的，signal为31

The problem of using third party Library

请教一下，在单调用judgeserver评测机时，想要加第三方库，在dockerfile中的run 后面添加了想要加入的包后，要如何重构镜像，放在docker-compose.yml文件中，让其他的配置都不变，能够正常运行呢？谢谢您！

api 请求包错

看日志, 应该是传入 参数问题

	"language_config": "py3_lang_config",

看了 client/Python/languages.py 确实是这个

使用项目里面的Dockerfile构建失败

我想问一下,我使用命令构建项目里面的Dockerfile文件报错应该怎么处理呢?
报错内容如下:

Judge Server Failed

Thanks for the maintainance, I'm trying to use the latest judge server, the building process is fine, but its health check fails, which makes backend server down. Seems like the new setup have some error.

请问如何获取TOKEN,能通过接口获取吗？

spj 编译的时候，并发的情况下会有抛异常

JudgeServer/server/compiler.py

Line 40 in e30664b

os.remove(compiler_out)

由于spj的编译输出文件是同一个文件，当有两个spj在编译的情况会有问题

docker 容器中可用pandas，但提交 `import pandas` 显示 runtime error.

我修改了容器为可写，并进入了容器安装了numpy, pandas，现在numpy正常，但提交 import pandas 显示 runtime error。请问是什么原因呢？如何能支持pandas呢？

ModuleNotFoundError: No module named 'idna'

使用registry.cn-hangzhou.aliyuncs.com/onlinejudge/judge_server的镜像健康检查失败，进入容器内部执行python3 service.py命令报以下错误,，自己构建的则没问题。

服务器环境下不能导入题目

Linux环境Ubuntu16.04不能导入题目，导入题目出现Server Error。我们环境是用阿里云服务器的。但是本地Linux也是Ubuntu16.04，导入题目却没有出现Server Error 能够正常导入题目。请问下，这是什么原因?谢谢

problem with addding js to language configs

I have added this config to language configs:

js_lang_config = {
   "run": {
       "exe_name": "solution.js",
       "command": "/usr/bin/nodejs {exe_path}",
       "seccomp_rule": "general",
   }
}

and this line to Dockerfile
RUN apt-get install -y nodejs

any code that is run with js language config returns runtime error.
when I run the code directly from docker I get the correct result I'm expecting

DockerFile 里面这一段 echo $phpJitOption > /etc/php/8.0/cli/conf.d/10-opcache-jit.ini，需要改成 php/8.1，因为现在8.1是正式版本，默认前面会安装PHP8.1，所以目录不对了，这个地方可能需要调整一下，不然之后8.2如果出来了又要改。

请问能否给个JudgeServer /judge的请求样例

您好，请问是否发一份JudgeServer /judge的请求样例
或者能不能帮我看看这是什么问题？
{ "src": "#include<stdio.h> int main() {int a,b; scanf(\"%d%d\", &a,&b); printf(\"%d\", a+b); return 0;}", "language_config": { "compile": { "src_name": "main.c", "exe_name": "main", "max_cpu_time": 3000, "max_real_time": 5000, "max_memory": 134217728, "compile_command": "/usr/bin/gcc -DONLINE_JUDGE -O2 -w -fmax-errors=3 -std=c99 {src_path} -lm -o {exe_path}" }, "run": { "command": "{exe_path}", "seccomp_rule": "c_cpp", "env": ["LANG=en_US.UTF-8", "LANGUAGE=en_US:en", "LC_ALL=en_US.UTF-8"] } }, "max_cpu_time": 3000, "max_memory": 134217728, "test_case_id": "normal", "output": "false" }

判题返回的数据中，cpu_time 和 real_time 分别是指什么？

您好，在 api 中我未找到有关 cpu_time 和 real_time 的描述，能说一下它们的意义吗？谢谢。

阿里云docker部署打，输出结果不正确，最后几位重复

阿里云上docker部署的，总是出现这种最后几个输出完全一样的结果。奇怪的是我本地跑同样的代码可以得到正确的结果

service.py 每隔6秒执行一次，请问这个是怎么实现的，能不能将时间改长一点。谢谢

[API] get JudgeClientError, "ping() argument after ** must be a mapping, not NoneType"

你好，

我參考 judgeserver api 寫一個python程式想要檢查system info。

import hashlib
import requests

token = hashlib.sha256('CHANGE_THIS'.encode('utf-8')).hexdigest()
headers = {'X-Judge-Server-Token': str(token), }
response = requests.post('http://172.18.0.3:8080/ping', headers=headers)
print(response.content)

卻得到 JudgeClientError 錯誤：

{"data": "TypeError :ping() argument after ** must be a mapping, not NoneType", "err": "JudgeClientError"}

請問怎麼解決??

能否支持下JavaScript语言?

我们在使用这个平台在公司内举办比赛 前端们也很希望参加进来 但是发现语言不支持 希望大佬们考虑一下~

entrypoint.sh多次调用导致多个gunicorn进程同时存在占用内存

外部的一个服务，能够通过entrypoint.sh启动这个docker里的服务，那个服务反复重启导致docker的内存爆炸。建议每次运行entrypoint.sh的时候先杀掉之前的gunicorn进程

编译时最大输出限制

JudgeServer/server/compiler.py

Line 22 in e81fc56

max_output_size=1024 * 1024,

为什么这个max_output_size限制了g++二进制文件输出的大小？

上图中分别为加上max_output_size与去掉max_output_size执行

/usr/lib/judger/libjudger.so \
    --exe_path=/usr/bin/g++ \
    --max_cpu_time=10000 \
    --max_real_time=20000 \
    --max_memory=134217728 \

    --gid=0 # > /opt/compile/result.log

的结果

subprocess.Popen

proc = subprocess.Popen(proc_args, stdout=subprocess.PIPE, stderr=subprocess.PIPE,shell=True)
out, err = proc.communicate()我运行测试的时候发现out和err都是空字符串，这是为什么？

请问有人遇到测试用例找不到之后进程睡眠占用内存的问题吗？

关于行尾空格影响结果

因行尾空格与样例不符影响判题结果，能否在判题时不考虑每行行尾空格

有比较完善的二次开发教程吗，本地启动一直报错，很多配置不知道要怎么改

有比较完善的二次开发教程吗，本地启动一直报错，很多配置不知道要怎么改

是否应该帮用户 rstrip 掉输出中间行末尾的空格？

#include <cstdio>
#include <cstring>
#include <iostream>
#include <algorithm>
using namespace std;
int main() {
    int singer1[6] = {8, 4, 6, 7, 5, 6};
    int singer2[6] = {5, 6, 3, 6, 4, 2};
    int singer3[6] = {3, 2, 4, 2, 3, 5};
    int num;
    scanf("%d", &num);
    printf(
        "%d %d %d   \n%d",
        singer1[num - 1], singer2[num - 1], singer3[num - 1],
        singer1[num - 1] + singer2[num - 1] + singer3[num -1]
    );
    return 0;
}

输出样例 1

8 5 3
16

用户输出

8 5 3   
16

这是一个测试用的程序，注意 "%d %d %d \n%d" 中，\n 之前的空格会导致答案错误。因为 Judger 在比较「用户输出」和「标准输出」时，只抹掉了用户输出最后一行的空格和换行符，输出中间行末尾的空格没有处理。

我把输出比较函数改成了如下

    def _compare_output(self, test_case_file_id, user_output_file):
        with open(user_output_file, "rb") as f:
            # 目前在上传测试用例时只去掉了最后一行的空格以及换行符，中间行末的空格没有去除，有待优化，但我们可以先帮用户 rstrip 掉
            output_lines = f.readlines()
            stripped_output_lines = [line.rstrip() for line in output_lines]
            content = b'\n'.join(stripped_output_lines)
        output_md5 = hashlib.md5(content.rstrip()).hexdigest()
        result = output_md5 == self._get_test_case_file_info(test_case_file_id)["stripped_output_md5"]
        return output_md5, result

请问镜像能不能往dockerhub上打包一份
