a simple, light-weight and highly maintainable online judge system for secondary education

一个简单、轻量化、易于维护的、为中学信息技术学科课业教学设计的 Online Judge 系统。

Online Judge?

在线评测系统(Online Judge,缩写 OJ)是一种在算法竞赛竞赛中用来测试参赛程序的在线系统,也可以用于平时练习。许多 OJ 网站会自发组织一些竞赛。此外,OJ 网站通常会设立用户排名,以用户的提交答案通过数多少或某个题目执行时间快慢为排名依据。(来源:维基百科

该项目从传统 OJ 的设计出发,针对中学信息技术学科课业教学进行优化:如支持在 Python 中进行文件读取、引入第三方库等操作;同时原生支持交互式测评,并提供了一套 testlib API。

Deploy

环境配置

由于 Sandbox 技术限制,评测端必须部署在 Linux 中。环境需求如下:

  • Python 3.6+
  • NodeJS 12+
  • 包管理器 pip & npm
  • 命令行工具 wget & cmake

配置文件为 ./config.yml,请复制 ./config.sample.yml./config.yml 并填写配置。为了网站安全,请务必填写 secret_key 选项为随机秘钥,登录插件等都依赖于此。

数据目录为 ./data,你可以从 @y3oj/demo-data 从下载示例数据。

为运行 Sandbox 请按照 @t123yh/simple-sandbox 配置系统。

网页端

使用 Flask & jinja2 开发,需要安装相关依赖。

pip install -r requirements.txt
python build-frontend.py
python run.py      # start server

前端

使用 Less 生成样式,第三方包托管在 @y3oj/thirdparty-host

npm install -g less uglifyjs
python build-frontend.py      # build static

build-frontend.py 提供两个参数:

  • --force,构建时强制重新下载第三方包,复制静态文件时强行覆盖。
  • --watch,启用 Watch Mode,依赖于系统 API 检测文件更改时自动重新构建。

评测端

使用 NodeJS 开发,沙盒由 @t123yh/simple-sandbox 提供,使用 websocket 与主程序通信。

再次提醒,请确保已经按照 @t123yh/simple-sandbox 配置系统。

cd y3oj-judger
git clone https://github.com/t123yh/simple-sandbox.git  # repo mirror: https://e.coding.net/memset0/y3oj/simple-sandbox.git
cd simple-sandbox && CXX=clang++-9 yarn install && yarn run build && cd ..
npm install
npm run judge-test      # run test
npm run judge-start     # start judge server

Sandbox Rootfs

另外需要构建一个沙盒所使用的 rootfs。这里用的是 archlinux,参考代码如下

/etc/pacman.d/mirrorlist pacman -Syy pacman-key --init && pacman-key --populate archlinux pacman -S python3 python-pip --noconfirm pip install flask numpy matplotlib pandas flask_wtf requests pyyaml flask_login --index-url https://pypi.douban.com/simple ">
wget -c https://mirrors.tuna.tsinghua.edu.cn/archlinux/iso/latest/archlinux-bootstrap-2021.10.01-x86_64.tar.gz -O sandbox-rootfs.tar.gz
mkdir -p ./sandbox-rootfs
sudo tar -zxvf sandbox-rootfs.tar.gz -C ./sandbox-rootfs  # remember `sudo`
cd ./sandbox-rootfs
mount ./root.x86_64/ ./root.x86_64/ --bind
sudo ./root.x86_64/usr/bin/arch-chroot ./root.x86_64/
mkdir -p /sandbox/working
echo "Server = https://mirrors.tuna.tsinghua.edu.cn/archlinux/\$repo/os/\$arch" > /etc/pacman.d/mirrorlist
pacman -Syy
pacman-key --init && pacman-key --populate archlinux
pacman -S python3 python-pip --noconfirm
pip install flask numpy matplotlib pandas flask_wtf requests pyyaml flask_login --index-url https://pypi.douban.com/simple
