Setup instructions need to be clear. I have no clue on how to run the judge, + register button is not shown in the home page+how can I access admin interface ? Please help me.

本OJ大约是1年前开始开发的，目前逐渐暴露出一些问题。打算进行一个比较大的重构，主要包括

• [x] vue.js重写所有前端页面
• [x] 前端后端的国际化，多语言和时区
• [x] 导入导出题目（但是目前考虑的hustoj的FPS格式还有些问题，可能在当前版本中也会做）
• [x] 更方便的添加多编程程序语言支持，统一配置规则（有些问题还没解决）题目选择可以使用的语言
• [x] 比赛的OI模式（排名，查看单独测试数据是否通过等）
• [x] SPJ更加方便的添加代码和测试
• [x] 超级管理员 - 管理所有 普通管理员- 默认创建小组内比赛和不能创建题目题目，但是可以通过两个选项允许
• [x] 完善后端的测试，跑CI
• [x] 代码风格问题
• [x] 题目和公告使用markdown编辑器
• [x] 判题服务器的健康检查和添加时候的检查

目前基本上只有我一个人在维护这个项目，时间不多，都是在工作之余做，但是放弃了也太可惜。如果有愿意参与的，可以回复一下。

Hello I am a beginner programmer. I tried many times to check the DB schema structure while looking at the code through the project, but it continued to fail because of insufficient knowledge. Can you teach me how to check and access the schema structure of a DB in Windows local environment?

前7天出完比賽題，Special Judge 測試為正常 前3天更新到 Version: 20181215 昨天開比賽的時候，有用到Special Judge的題目，沒有CE的Code全部爆System Error

比賽途中稍微改spj的code推測錯誤點，似乎在這裡

input = fopen(args[1], "r");
user_output = fopen(args[2], "r");
if(input == NULL || user_output == NULL){
    printf("Failed to open output file\n");
    close_file(input);
    close_file(user_output);
    return ERROR;
}

但不確定是input還是user_output出問題

目前解決是降版處理 Version: 20180815

这咋整，容器端口绑定冲突了……

在提交issue之前请

• 认真阅读文档 http://docs.onlinejudge.me/#/
• 搜索和查看历史issues
• 安全类问题请不要在 GitHub 上公布，请发送邮件到 [email protected]，根据漏洞危害程度发送红包感谢。

然后提交issue请写清楚下列事项

 - 进行什么操作的时候遇到了什么问题，最好能有复现步骤  - 错误提示是什么，如果看不到错误提示，请去data文件夹查看相应log文件。大段的错误提示请包在代码块标记里面。

• 你尝试修复问题的操作
• 页面问题请写清浏览器版本，尽量有截图

附上例程

#include <stdio.h>
int main(){
  int n;
  int k;
  scanf("%d",&n);
  while(n--){
    int i = 2;
    scanf("%d",&k);
    while(i<=k){
      if(k%i==0){
        if(k!=i){
          printf("%d\r\n",0);
          break;
        }else{
          printf("%d\r\n",1);
        }
      }
      i++;
    } 
  }
}

和之前那个issue不太一样...

我在执行docker build -t judger /home/OnlineJudge/dockerfiles/judger/这个的时候，为什么到一半的时候会出现 W: Failed to fetch http://mirrors.aliyun.com/ubuntu/dists/trusty-proposed/main/source/Sources Hash Sum mismatch

E: Some index files failed to download. They have been ignored, or old ones used instead. The command '/bin/sh -c apt-get update' returned a non-zero code: 100 这样的问题？

我使用的是 https://github.com/QingdaoU/OnlineJudgeDeploy/tree/2.0 一键部署，我想修改前端样式，于是我git下来的onlinejudge_FE，请问修改之后该如何在我现在已经在本地部署好的网站上显示，还是说使用一键部署好的OJ是没办法自己更新前端源码的？

在 FAQ 里：

Java specifications?
All programs must begin in a static main method in a Main class. Do not use public classes: even Main must be non public to avoid compile error.Use buffered I/O to avoid time limit exceeded due to excesive flushing.

excesive flushing 应为 excessive flushing

About presentation error?
There is no presentation error in this oj.The judger will trim the blacks and wraps in your ouput's last line. if it's still different with the correct output, the result will be Wrong Answer.

ouput's last line 应为 output's last line trim the blacks 应为 trim the blanks

还有很多标点符号后面的空格也缺失了。

请教如何解决上传 FPS 问题出现 Server Error 错误？ 请问具体原因是什么？如何解决呢？

环境

按官方教程使用 docker-compose 部署，还算顺利

问题描述

从 zhblue/freeproblemset 下载了样题，尝试通过 Import FPS Problems (beta) 来导入，报 Server Error

已经尝试

• 查看试题格式，使用 EasyFPSViewer 查看是正常的
• 手工新建试题，正常，且能正确判分
• 进入容器内部，查看日志

用交互式模式，进入容器内部 docker exec -it oj-backend /bin/sh

切换到日志文件夹 # cd /data/log/

查看日志 # tail gunicorn.log 提示信息如下：

[2022-12-09 00:41:57] - [ERROR] - [sentry.errors:684]  - Sentry responded with an API error: RateLimited(None)
b'Sentry responded with an API error: RateLimited(None)'

多谢！

def search(arr , t): for i in range(len(arr)): if arr[i] == t: return i return "-1"

n, m = map(int, input().split()) nums = [int(input()) for _ in range(n)] for _ in range(m): t = int(input()) print(search(nums,t))

按照老師的作法，沒有辦法在同樣的時間複雜度下通過測試，希望放開一些標準，
