## 本机环境
|
||||
|
||||
**Docker 可用,全套依赖都能在本机跑起来**(PostgreSQL、Redis、判题沙箱),
|
||||
镜像也能在本机构建并完整演练上线。这一点和上一代不同,别沿用「本机跑不起来后端」的旧假设。
|
||||
镜像也能在本机构建并完整演练上线。这一点和上一代不同,别沿用"本机跑不起来后端"
|
||||
的旧假设。
|
||||
|
||||
```bash
|
||||
bun install
|
||||
bun run db:up # 起 postgres(5433) / redis(6380) / 判题沙箱(8081)
|
||||
bun run db:migrate # 空库会从 0000 自举出全部结构
|
||||
bun run dev # api(3000) + worker + web(5173) 一起起
|
||||
```
|
||||
|
||||
首次要先建 `.env`(照 `.env.example`)。判题机 token 两边必须一致:
|
||||
`.env` 的 `JUDGE_SERVER_TOKEN` 和 `docker/.env` 的 `OJ2_JUDGE_TOKEN`。
|
||||
|
||||
**Bun 版本是锁死的**:单二进制把运行时一起打进去,CI 装的是几、线上跑的就是几。
|
||||
升级要改三处 —— 根 `package.json` 的 `packageManager`(CI 的 setup-bun 读它)和
|
||||
`@types/bun`、`docker/Dockerfile` 的 `oven/bun:x.y.z` —— 然后 `bun install`。
|
||||
`bunfig.toml` 设了 `minimumReleaseAge = "3d"`,新发布不满 3 天的包装不上,`@types/bun` 除外。
|
||||
|
||||
常用检查:
|
||||
|
||||
```bash
|
||||
bunx vp run verify # 下面这些一次跑完,带缓存(没改过的直接跳过)
|
||||
bun run check # 格式检查 + lint,不含类型检查
|
||||
bun run fmt # 格式化(bun fmt),全仓一把
|
||||
bun run lint # lint(Oxlint),有一条 warning 就算失败
|
||||
bun run --filter '@oj2/api' typecheck # 后端类型检查
|
||||
bun run --filter '@oj2/api' check:routes # 路由遮蔽检查,加完路由跑一下
|
||||
bun run --filter '@oj2/api' check:ast # AST 节点类型检查,升级 tree-sitter 后跑
|
||||
cd apps/web && bun run type-check # 前端类型检查
|
||||
cd apps/web && bun run build # 前端构建(不在 verify 里)
|
||||
cd apps/web && bun run build # 前端构建
|
||||
```
|
||||
|
||||
**lint 和任务编排走 Vite+**(`vite-plus`,`vp` 命令),**格式化走 Bun 自带的 `bun fmt`**,
|
||||
配置都只在根目录的 `vite.config.ts` 一份:`fmt` 块(Oxfmt 的写法,`bun fmt` 直接读它;
|
||||
`semi: false`、`singleQuote: true`、`printWidth: 160`)、`lint` 块(Oxlint,`denyWarnings`)、`run.tasks`
|
||||
(`verify` 和它依赖的四个检查)。**别用 `vp fmt` / `vp check`**:Oxfmt 和 `bun fmt` 只在
|
||||
长 CSS 值列表的折行上不一样,混着跑会把 `apps/web/public/style.css`、`apps/web/src/oj/learn/learn.css` 来回改
|
||||
(`vp fmt --list-different` 能列出当前受影响的文件)。前端自己的构建
|
||||
配置在 `apps/web/vite.config.ts`,和根目录那份无关。
|
||||
|
||||
- 格式化只管代码:`.md` / `.yml` / `.json` / `.toml` 在 `fmt.ignorePatterns` 里排掉了
|
||||
(文档的中文表格、compose 的逐行注释是手排的),`src/db/meta/` 快照和 unplugin 的两个
|
||||
`.d.ts` 也排掉了。
|
||||
- **`run.tasks` 里一律经 `bun run <脚本>` 调**,不直接写 `tsc`:任务定义在根包,PATH 是根目录
|
||||
的 `node_modules/.bin`,直接写拿到的是根目录的 TS 5.9 而不是 `apps/api` 的 TS 7。
|
||||
- 任务名不能和根 `package.json` 的脚本重名(Vite+ 直接报错),所以 `verify` 没有对应的
|
||||
`bun run` 脚本,用 `bunx vp run verify`。
|
||||
- 缓存在 `node_modules/.vite/task-cache`,按读到的文件内容做指纹;怀疑缓存不对时删掉它。
|
||||
- **改完代码顺手跑一下 `bun run fmt`**。
|
||||
|
||||
⚠️ **前端类型检查只能走 `bun run type-check` 这个脚本。** 两条看起来等价的路子都会**静默
|
||||
通过**:`vue-tsc --noEmit -p tsconfig.json` 检查 0 个文件(那个 tsconfig 是 `files: []` +
|
||||
references 的壳,真正的配置在 `tsconfig.app.json`),而 `vite build` 根本不做类型检查。
|
||||
改完 .vue / .ts 别拿构建当验证。

|
||||
|
||||
**不要写测试** —— 沿用上一代的项目约定。验证靠实跑:起服务、打接口、看结果。
|
||||
本机 Docker 全套都能起,实跑的成本比想象中低。
|
||||
|
||||
## 提交
|
||||
|
||||
**直接在 `main` 上干活,不开特性分支。** 注意 **push `origin` 的 `main` 就会部署**:
|
||||
开发机上的 gitea-runner 跑 `.gitea/workflows/deploy.yml`,进度在 git.xuyue.cc 的 Actions 页面。
|
||||
GitHub 那份只剩手动触发的备用路线。见 `docs/deploy.md`。
|
||||
|
||||
提交信息用中文,格式 `type(范围): 从用户视角描述现象`,例如
|
||||
`fix(流程图): 「重新判题」从来没成功过,而且会把原来的评分清掉`。
|
||||
常用 type:`fix` / `feat` / `refactor` / `perf` / `chore` / `style`。
|
||||
|
||||
## 几件必须知道的事
|
||||
|
||||
后端专属的坑 —— 单二进制不能依赖 node_modules、路径走 `runtime.ts`、SQL 判题 spawn 自己、
|
||||
路由遮蔽、出参用 `satisfies` 不用 `parse`、外键删除动作与迁移 —— 在 **`apps/api/CLAUDE.md`**,
|
||||
动 `apps/api` 的文件时会自动加载。下面是全仓通用的。
|
||||
### 单二进制是有代价的
|
||||
|
||||
`apps/api` 编译成 `bun build --compile` 的单二进制,所以**运行时不能依赖
|
||||
node_modules**。任何 `require.resolve` / `Bun.resolveSync` / `__dirname` 去找文件的
|
||||
写法,本地都正常、编译后都会炸,而且**只在离开仓库目录后才炸**(在仓库里跑时它顺着
|
||||
cwd 摸到了 node_modules,假装没事)。
|
||||
|
||||
资源要用 `with { type: "file" }` 内嵌。`.node` 原生模块还要额外注意:这个写法
|
||||
只有打包器认、`bun run` 不认,所以必须按形态分叉 —— 见 `apps/api/src/vendor/jieba.ts`
|
||||
的注释,那里把坑写全了。
|
||||
|
||||
**改完这类代码,dev 和编译两种形态都要跑一遍。** 我吃过亏:只验了编译产物,
|
||||
dev 直接起不来。
|
||||
|
||||
### 路径解析看 `runtime.ts`
|
||||
|
||||
编译后 `import.meta.dir` 恒为 `/$bunfs/root`,往上三级就是文件系统根。
|
||||
相对路径一律走 `runtime.ts` 的 `pathBase`,别自己拼。
|
||||
|
||||
### SQL 判题会 spawn「自己」
|
||||
|
||||
`judge/sql/index.ts` 起的子进程是二进制自身 + `sql-child` 子命令(因为编译后磁盘上
|
||||
没有 child.ts 可以 spawn)。所以**入口必须有 argv 分发**,否则「起自己」变成
|
||||
「把整个程序再跑一遍」→ 指数级 fork。这不是假想,开发时炸过一次开发机。
|
||||
`OJ2_SQL_CHILD` 那道递归闸不要删。
|
||||
|
||||
### 加路由要防遮蔽
|
||||
|
||||
**Hono 按注册顺序匹配,不是静态优先**(实测确认过,别凭直觉)。`/problems/:id`
|
||||
注册在 `/problems/random` 前面的话,后者永远进不去 —— 而且不报错、不警告,
|
||||
只是静默走进前一条的 handler。阶段 4 真实发生过一次,两个教师用的分析端点被吃掉,
|
||||
一直到评审才发现。
|
||||
|
||||
加完路由跑 `bun run --filter '@oj2/api' check:routes`。
|
||||
|
||||
### 判题状态码不能改
|
||||
|
||||
@@ -106,89 +106,264 @@ GitHub 那份只剩手动触发的备用路线。见 `docs/deploy.md`。
|
||||
这些整数是**落库的值**:12 万条历史提交的 `submission.result` 就是它们,判题沙箱回的也是
|
||||
这套编码,所以只能新增、不能改已有的含义。题目表情 reaction 的语义 key 同理。
|
||||
|
||||
### 判题机是 go-judge,判题流程在后端
|
||||
### 出参不 `parse`,用 `satisfies`
|
||||
|
||||
`compose.*.yml` 里的 `oj2-judge-3` **不在任何 registry 上**:`docker/judge/` 把
|
||||
[go-judge](https://github.com/criyle/go-judge) 的二进制和 gcc / python 装进一个镜像,本机构建。
|
||||
go-judge 只管「在沙箱里跑一条命令」,**编译、逐个测试点运行、比对输出、定状态码都在
|
||||
`apps/api/src/judge/sandbox.ts`**,口径逐条照搬了 2026-10 之前的 QingdaoU/JudgeServer
|
||||
(输出 rstrip 后比 md5、stdout 和 stderr 合在一起比、地址空间限两倍内存、16MB 输出上限 …),
|
||||
出参也还是它的形状 —— 12 万条历史提交的 `info` 就是这个形状。动那个文件前先读它顶部的注释。
|
||||
**后端的响应一律 `satisfies XxxType`,不要写 `xxxSchema.parse({...})`。**
|
||||
出参是后端自己刚拼出来的字面量,TS 已经在编译期校验过;再 `parse` 一遍拿不到任何新
|
||||
信息,唯一可能失败的输入是**库里的历史数据**,而失败的代价是 500。这一层原来有 136 处,
|
||||
已经全部撤掉,撤的时候当场炸出两个一直存在的线上 500:
|
||||
|
||||
- 构建、分发、改名的步骤见 `docker/judge/README.md`。**服务器和机房各有各的判题沙箱,两边都要装。**
|
||||
- 判题机容器是 `privileged` 的(go-judge 要自己建 cgroup 和 namespace),别「顺手」改回 `read_only` + `cap_drop`。
|
||||
- 判题机不再主动报心跳,后台「判题机列表」是 worker 每 5 秒去问一次记下的(`judge/heartbeat.ts`)。
|
||||
- 编译/运行命令在 `apps/api/src/judge/languages.ts`,不在镜像里。gcc-14 把隐式函数
|
||||
声明等提成了 error(`-w` 压不住),那边的 `cLooseErrors` 几个 `-Wno-error=` 就是
|
||||
为此加的 —— 删掉它们等于让一批历史题解和 C 教程示例集体 CE。
|
||||
- **判题沙箱只认 C / C++ / Python。** Java / JavaScript / Golang 连同镜像里的
|
||||
JDK / Node / Go 在 2026-09 一起砍了(前端本来就没给入口,12 万条提交里它们共 62 条),
|
||||
契约 `judgeLanguageSchema` 里的键留着是为了渲染那 62 条历史提交。
|
||||
**`Python3` / `Python2` 这两个旧值已经没有了** —— 0019 迁移把 104530 条提交、937 道题、
|
||||
1235 个用户的成就指标并成了一个 `Python`,0020 顺手把那三种语言从题目的可选语言里摘掉
|
||||
(不摘的话 84 道题的语言下拉还能选 Java,提交必 SYSTEM_ERROR)。代码里也不再认旧值(别名表 2026-10 删了),
|
||||
**回滚到 0019 之前要连数据一起回**,只滚代码会让 Python 提交全炸。
|
||||
- 换完镜像跑 `bun docker/judge/smoke.ts`:三种语言、六种状态码、gcc 宽松度一起核。
|
||||
- `adminProblemSchema.lastUpdateTime` 写的是 `z.string()`,但 `problem.last_update_time`
|
||||
是全库唯一可空的列(961 道题里 470 道是 NULL)——**后台打开任何一道没编辑过的老题都是 500**;
|
||||
- `embeddedSubmissionSchema` 从 `submissionDetailSchema` 继承了 `problemDisplayId` 却没
|
||||
omit,而路由只填了同义的 `problem`——**凡是收到过站内信的人,消息页都打不开**(列表为空
|
||||
时才碰巧不炸,所以一直没人报)。
|
||||
|
||||
### AST 代码规则:一张表,外加一个机器检查
|
||||
两个都是「读出侧校验」自己造出来的故障,不是它拦住的故障。历史上还有两次同类:
|
||||
`exerciseSchema` 按题型收紧后一行脏数据让整条练习列表 500;`info` 写成
|
||||
`union([完整形状, z.object({})])` 后对不上的一律落进空对象那支且 parse **成功**,
|
||||
管理员详情页的测试点表格静默消失(全量核出 9163/124192 条中招,RE 8480/8480 全中——
|
||||
沙箱在非正常退出的测试点上写 `output_md5: null`,而契约写的是 `z.string()`)。
|
||||
|
||||
契约的 `AST_NODE_TARGETS_BY_LANGUAGE` 是**唯一**一张表(`label` 给界面、`node` 给判题机),
|
||||
判题机侧没有第二张表,所以加 target 漏配节点类型在结构上不可能。但**配错**仍然可能,
|
||||
而且完全静默 —— 节点类型对不上就是「必须使用 X」永远失败、「不能使用 X」永远通过。
|
||||
**闸设在写入侧,一共三处形态:**
|
||||
|
||||
```bash
|
||||
bun run --filter '@oj2/api' check:ast # 升级 tree-sitter-* 之后一定要跑
|
||||
```
|
||||
1. **入参 `safeParse`**(58 处,全部保留)—— 请求体进来的那一刻校验,对不上回 400。
|
||||
2. **`db/schema.ts` 的 `.$type<>()`** —— 枚举型的列(`submission.result` / `.language`、
|
||||
`problem.difficulty` / `.languages`、`achievement.rarity`、`exercise.type`…)和几个
|
||||
形状确定的 JSONB(`problem.template` / `.astRules` / `.sqlConfig` / `.sqlDisplay`、
|
||||
`acm_contest_rank.submission_info`)直接在列上收窄,只影响 TS、不产生任何 SQL。
|
||||
这些断言**逐列拿根目录那份生产备份核过**(12.4 万条提交的 `result` 全在 `-2..6,10`、
|
||||
961 道题的 `languages` 全是合法数组、10050 条榜单条目形状全对)。
|
||||
加这类断言前先照样核一遍,别凭直觉。
|
||||
3. **语义校验函数** —— `astRulesError()`、`services/exercise.ts` 的 `exerciseDataError`。
|
||||
|
||||
判题机只认 C / C++ / Python(`AST_SUPPORTED_LANGUAGES`),别的语言配了规则一条都不会跑,
|
||||
所以后台不给它们开 tab —— **看得见却不检查**比没有更糟。C++ 的调用形态和 C 不一样、
|
||||
规则的语义校验为什么不挂在 zod 上,见 `docs/ast-rules.md`。
|
||||
**JSONB 原文(`submission.info` / `statistic_info` / `exercise.data`)仍然一律放行**,
|
||||
读出侧不收窄:它们的形状真相在判题机那边。
|
||||
|
||||
query 里的筛选值要和收窄过的列比较时走 `routes/helpers.ts` 的 `asFilterValue()` ——
|
||||
那是纯类型交接,**不加校验**:在那儿拦一道会把「筛出空列表」变成「筛条件被忽略、
|
||||
返回全部」。前端那侧(`utils/contract.ts` 为什么只挂三处)见 `apps/web/CLAUDE.md`。
|
||||
|
||||
唯一还留着 `parse` 的地方是 `judge/events.ts` 的 `parseSubmissionEvent` ——
|
||||
那是从 Redis 收回来的报文,真边界,且失败返回 `null` 而不是 500。
|
||||
|
||||
### AST 代码规则有两张表,必须同增同减
|
||||
|
||||
契约的 `AST_NODE_TARGETS_BY_LANGUAGE`(target → 中文名)决定后台下拉能选什么,
|
||||
`apps/api/src/judge/ast.ts` 的 `mappings`(target → tree-sitter 节点类型)决定判题机
|
||||
认得什么。**加节点类型时两边都要加**,运算符表 `AST_OPERATOR_TARGETS_BY_LANGUAGE` 同理。
|
||||
|
||||
只加一边是**静默错判**:判题机 `mapping[target] ?? target` 拿裸名去比节点类型,
|
||||
C 的语法树里永远不存在 `list_comprehension`,于是「必须使用列表推导式」永远失败、
|
||||
「不能使用 f-string」永远通过,两头都不报错,只有学生受着。原来那张表是 C/Python
|
||||
混在一起的 15 条,整份铺成下拉,给 C 题也能选到 Python 专有节点——就是这么来的。
|
||||
|
||||
判题机只认 `AST_SUPPORTED_LANGUAGES` 里的语言(C / C++ / Python3)。别的语言配了规则
|
||||
一条都不会跑,所以后台不给它们开 tab,题目页也不把它们的规则展示成「要求」——
|
||||
**看得见却不检查**比没有更糟。
|
||||
|
||||
C++ 的语法表是「C 的全集 + C++ 独有的几条」,因为 tree-sitter-cpp 继承 tree-sitter-c,
|
||||
C 那 14 个 target 在 C++ 树里逐个实测通用。但**调用形态两者不同**,加语言时必须一起看:
|
||||
`a.push_back()` 和 `p->push_back()` 在 C++ 都是 `call_expression` + `field_expression`,
|
||||
不是 Python 的 `attribute`;`std::sort(...)` 的 function 是 `qualified_identifier`
|
||||
而不是 `identifier`,所以 `functionCalls` 对 C++ 额外比一次 `::` 末段——否则学生写了
|
||||
`using namespace std` 与否会得到不同的判定结果。
|
||||
|
||||
规则的语义校验在 `astRulesError()`,不在 zod 的 refine 上:`astRulesSchema` 同时用于
|
||||
**读**后台题目详情,在读路径上抛错会让历史脏数据把整个题目详情打不开。同理,保存前
|
||||
先 `pickAstRules()` 剔除够不着的分组再校验,否则早年配过 C++ 规则的题会把老师锁死
|
||||
——tab 里看不到那组规则,保存却被拦下。
|
||||
|
||||
### 比赛只有 ACM 模式
|
||||
|
||||
没有 OI。上一代残留的 OI 分支在阶段 0 已经砍掉,不要「顺手补回来」。
|
||||
没有 OI。上一代残留的 OI 分支在阶段 0 已经砍掉,不要"顺手补回来"。
|
||||
|
||||
### 前端基线是 Chrome 105
|
||||
### 前端要兼容老 Chrome
|
||||
|
||||
机房**部分**电脑是 Chrome 105,其余更新 —— 按最低那档定基线。
|
||||
**`@vitejs/plugin-legacy` 和写死的 polyfill 清单别删**(vite 8 默认 target 是 `chrome111`)。
|
||||
升级前端依赖后要重新审计 polyfill 清单,步骤与 View Transitions 的降级见 `apps/web/CLAUDE.md`。
|
||||
机房电脑 Chrome < 94。`mermaid-legacy` 等 fallback 依赖和 vite 的构建 target
|
||||
不能动,`vite.config.ts` 里有注释说明。
|
||||
|
||||
### 时间只有一个锚点:`apps/api/src/time.ts`
|
||||
## 数据库
|
||||
|
||||
**凡是要把一个时刻换算成「哪一天 / 几点 / 哪一年」,一律走那个模块。** 不要写
|
||||
`new Date(x).getHours()`、`setHours(0,0,0,0)`、`getFullYear()`、`new Date(y, m, d)` 这类跟
|
||||
**进程时区**走的代码 —— 容器是 UTC、开发机是本机时区,两边答案不同而且不报错。
|
||||
SQL 里要按日历切,用 `localTime(列)`(生成 `列 at time zone 'Asia/Shanghai'`),
|
||||
别依赖数据库会话时区。
|
||||
Drizzle schema 最初是 `drizzle-kit pull` 从生产库拉出来的,所以它长得像 Django 建的表
|
||||
(表名、bigint/int4 混用),`schema.ts` 顶部记了哪些地方是手工修的。
|
||||
|
||||
**分层:存 UTC 时刻 → 后端判定按东八区 → 出参 ISO UTC → 前端按东八区渲染。**
|
||||
**外键的删除动作从 0010 起是显式的**,不再是 Django 留下的一律 NO ACTION:
|
||||
|
||||
- **存**:时间列全是 `timestamptz`,写侧一律 `new Date().toISOString()`。
|
||||
- **判定**:日历语义走 `time.ts`,SQL 用 `localTime()`。
|
||||
- **出参**:`db/index.ts` 给 OID 1184 挂了 parser,读出来的时刻统一成 ISO 8601 UTC,
|
||||
**微秒必须保留**(截成毫秒会让翻页每页丢一条、班级 AC 排名少 1)。
|
||||
- **渲染**:前端 `parseTime()` / `zonedParts()` 按同一个固定偏移取东八区部件
|
||||
(见 `apps/web/CLAUDE.md`)。
|
||||
- **CASCADE**:父行消失后子行必然无意义、且不构成「学生做过什么」的证据 —— 中间表
|
||||
(problem_tags)、题单/教程/成就的组成部分、一对一附属(user_profile)与可重算的
|
||||
缓存(user_stat)。
|
||||
- **NO ACTION(即拦住)**:需要人看见的删除 —— `submission.problem_id`、以及 `user`
|
||||
的绝大多数外键。删用户撞外键会被 handler 翻译成「请改为禁用账号」,这是有意的。
|
||||
|
||||
时区常量 `TIME_ZONE` / `TIME_ZONE_OFFSET_MINUTES` 在 `packages/contract/src/time.ts`,
|
||||
前后端共用一份,按**固定偏移**算(大陆 1991 年起没有夏令时),与旧栈的东八区口径一致。
|
||||
**再动日历口径之前先读 `docs/timezone.md`**,那里有实测数据和核实方法;
|
||||
Dockerfile 的 `TZ` 和数据库连接的 `TimeZone` 是**刻意不设**的,别「顺手补上」。
|
||||
**加新子表时必须回来想一遍该走哪一档**,别默认新外键会自己连坐 —— drizzle 不写
|
||||
`.onDelete()` 就是 NO ACTION,而 0010 只改了当时存在的那批。
|
||||
|
||||
**schema 现在归 OJ2 独占。** 旧后端已下线,「改 schema 要考虑回滚」这条约束不再存在,
|
||||
结构变更走下面的 migration 正常演进即可。
|
||||
|
||||
### 改 schema 走 drizzle migration
|
||||
|
||||
`bun run db:generate`(造迁移文件)→ `bun run db:migrate`(按 `drizzle.__drizzle_migrations`
|
||||
增量执行),就是 Django `makemigrations` / `migrate` 的等价物。索引/结构变更走这条,
|
||||
不要再手写 SQL 往 `docs/specs/` 里塞。
|
||||
|
||||
**部署时自动执行。** `docker/deploy.sh` 在「构建镜像」之后、「起栈」之前会跑
|
||||
`oj2-api migrate`,失败就中止部署(旧容器原样还在跑)。CI 走的也是 deploy.sh,
|
||||
所以不需要给 GitHub 配数据库凭据,也不用把生产库对外开放。
|
||||
|
||||
迁移文件**不内嵌进二进制**,随镜像装在 `/usr/local/share/oj2/migrations`
|
||||
(见 `runtime.ts` 的 `migrationsDir`、Dockerfile 里那两条 COPY)。这样 drizzle 的
|
||||
`migrate()` 能原样用——它靠 `meta/_journal.json` 自动发现迁移,**新增迁移不用改任何
|
||||
代码**。内嵌就得为每条迁移手写一行 import,那是迟早会漏的账。
|
||||
|
||||
**破坏性迁移默认拦截。** 含 `DROP TABLE` / `DROP COLUMN` / `DROP SCHEMA` /
|
||||
`ALTER COLUMN ... TYPE` / `TRUNCATE` 的迁移会让部署停在迁移这步并退出 4,
|
||||
需要确认备份后显式放行:
|
||||
|
||||
```bash
|
||||
OJ2_ALLOW_DESTRUCTIVE=1 docker/deploy.sh
|
||||
```
|
||||
|
||||
`DROP INDEX` / `DROP CONSTRAINT` 不算——它们不掉数据,拦了只会让人习惯性带上放行开关。
|
||||
**空库自举时这道闸不生效**:没有数据可丢,0002 那串 `DROP ... IF EXISTS` 全是空转,
|
||||
拦下来只会逼每个新环境都带一次放行开关,把它训练成习惯动作。
|
||||
|
||||
**放行的三条路,别记错:**
|
||||
|
||||
1. 服务器上手工部署:`OJ2_ALLOW_DESTRUCTIVE=1 docker/deploy.sh`。
|
||||
2. CI(`.github/workflows/deploy.yml`):**必须先手工触发**并在
|
||||
`workflow_dispatch` 上勾 `allow_destructive`。push 触发拿不到这个 input,值恒为空
|
||||
—— 也就是说**自动部署永远不会执行破坏性迁移**,只会停在闸门上把工作流判红。
|
||||
这是有意的:那种改动得有人先确认备份。
|
||||
3. 先单跑迁移把结构推到位,再 push 代码:迁移一旦记进
|
||||
`drizzle.__drizzle_migrations` 就不会再跑,后续自动部署里它已不是 pending,
|
||||
自然不触发闸门。多环境共库时(机房 + 服务器)推荐这条。
|
||||
|
||||
**空库能自举了。** `oj2-api migrate` 指向一个空库时直接从 `0000` 建起:
|
||||
|
||||
```bash
|
||||
DATABASE_URL=postgres://... oj2-api migrate
|
||||
# 空库,从 0000 开始自举。
|
||||
# 待执行 15 条迁移,开始。
|
||||
# ✓ 0000_crazy_gateway
|
||||
# ✓ 0001_add_submission_public_create_time_idx
|
||||
# ✓ 0002_drop_django_leftovers
|
||||
# …
|
||||
# ✓ 0014_drop_django_migrations
|
||||
```
|
||||
|
||||
`0000_crazy_gateway.sql` 原本是 `drizzle-kit pull` 的产物、整份被 `/* */` 包着、可执行
|
||||
语句 0 条,所以以前新库只能先手工 `psql -f docs/specs/schema.sql`。现在它的内容由那份
|
||||
生产 dump 机械转换而来(去掉 psql 专有指令、去掉 7 张 Django 遗留表及其索引外键,
|
||||
其余原样保留)。**实测**:空库自举出来的结构,和「灌 schema.sql + 打基线 + 跑迁移」
|
||||
这条老路子跑出来的结构,`pg_dump --schema-only` 逐字节一致(734 行,零差异)。
|
||||
|
||||
改 0000 对生产库没有影响 —— migrator 只比 `created_at`、**从不校验 hash**
|
||||
(`pg-core/dialect.js` 里就一句 `Number(lastDbMigration.created_at) < migration.folderMillis`),
|
||||
而生产库那行 `baseline-0000-faked` 早把它挡在门外了。
|
||||
|
||||
⚠️ **0000 的注释里不要出现 statement-breakpoint 那个分隔标记的字面量。**
|
||||
`readMigrationFiles` 是纯文本切分,不管它在不在注释里,照切不误 —— 注释被从中间切开,
|
||||
后半截当成 SQL 发出去,报的是 `syntax error at or near "。"` 这种和真实原因毫不相干的错。
|
||||
|
||||
**给一个已经存在的库做基线**:drizzle 没有 `--fake-initial`,`migrate` 见到空的
|
||||
`__drizzle_migrations`、库里却已经有表,会拒绝执行并 exit 3(裸跑 `drizzle-kit migrate`
|
||||
的话则是从 `0000` 撞上已存在的表、整个事务回滚,**而且 exit 1 却一个错误都不打印**)。
|
||||
对已有数据的库第一次跑之前,先手插一行把 `0000` 标记成已执行:
|
||||
|
||||
```sql
|
||||
CREATE SCHEMA IF NOT EXISTS drizzle;
|
||||
CREATE TABLE IF NOT EXISTS drizzle.__drizzle_migrations (
|
||||
id SERIAL PRIMARY KEY, hash text NOT NULL, created_at bigint);
|
||||
INSERT INTO drizzle.__drizzle_migrations (hash, created_at)
|
||||
VALUES ('baseline-0000-faked', 1786070652521); -- = meta/_journal.json 里 0000 的 when
|
||||
```
|
||||
|
||||
migrator 只比 `created_at`,不校验 hash,所以 hash 随便填。
|
||||
|
||||
**已知的三个坑**(`meta/0000_snapshot.json` 是 `pull` 出来的,没法无损还原 Django 建的
|
||||
schema,下面三处已经修过了,别让它们回潮):
|
||||
|
||||
- ~~**快照里的 Django 序列**~~:已随 `0002_drop_django_leftovers` 删表一并解决,
|
||||
`tablesFilter` 也移除了。(历史原因:`tablesFilter` 只过滤表、不过滤它们的序列,
|
||||
于是 `generate` 会吐出 5 条 `DROP SEQUENCE`。)
|
||||
- **bigint 上限精度**:`pull` 生成的 `maxValue: 9223372036854775807` 是 JS number 字面量,
|
||||
round-trip 成 `...776000`,每次 generate 都会多出 10 条 `ALTER COLUMN ... SET MAXVALUE`。
|
||||
已改成字符串。
|
||||
- **表达式索引的 opclass**:`problem_tag_name_ci_unique` 在快照里带 `opclass`,但 drizzle
|
||||
自己序列化不出来,导致每次都 drop + recreate。已从快照里去掉。
|
||||
|
||||
**还有一个写代码时要绕开的**:
|
||||
|
||||
- **`.op()` 会吞掉索引方向**:真正的根因不是 `.desc()`,是 opclass。drizzle-kit 的
|
||||
`CreatePgIndexConvertor` 里那个三元一旦走进 opclass 分支就回不到方向分支:
|
||||
`${it.opclass ? ` ${it.opclass}` : it.asc ? "" : " DESC"}`。而 `drizzle-kit pull`
|
||||
给**每一列**都挂了 `.op(...)`,所以本仓库里"写了 `.desc()` 却生成不出 DESC"每次都会重演。
|
||||
|
||||
**要方向就别写 `.op()`。** 不写没有任何代价——`int4_ops` / `timestamptz_ops` 本来就是
|
||||
这些类型的默认 opclass,写了等于没写。实测(drizzle-kit 0.31.10,探针索引跑过 generate):
|
||||
|
||||
| schema.ts | 生成的 SQL |
|
||||
|---|---|
|
||||
| `.desc().nullsFirst().op("timestamptz_ops")` | `"create_time" timestamptz_ops` ← 方向丢了 |
|
||||
| `.desc().nullsFirst()` | `"create_time" DESC NULLS FIRST` ✅ |
|
||||
| `.desc()` | `"create_time" DESC NULLS LAST` ✅ |
|
||||
|
||||
所以**多列混合方向的索引可以正常 generate**,不必手写。
|
||||
|
||||
假 diff 的机制也要理解对:带 `.op()` 时快照记的是 `asc: false`,SQL 建出来却是 ASC,
|
||||
**分歧在快照和真实库之间**,不在快照和 schema.ts 之间——所以再跑 generate 是干净的,
|
||||
要等到下次 pull 才炸出来。这是当初难定位的原因。
|
||||
|
||||
### 迁移执行器是自己的,不是 drizzle 那个
|
||||
|
||||
`db/migrate.ts` 不调用 drizzle 的 `migrate()`,自己按 journal 逐条执行。换掉它是因为
|
||||
`pg-core/dialect.js` 里那个实现有两条硬伤:
|
||||
|
||||
1. **所有待执行的迁移共用一个事务**,第 3 条失败会把第 1、2 条一起回滚。现在是**一条一个
|
||||
事务**,语义和 Django `migrate` 一致,失败时也说得清库停在哪儿。
|
||||
2. 正因为全在事务里,`CREATE INDEX CONCURRENTLY` 一律跑不了,没有开关。
|
||||
|
||||
记账行的写法和 drizzle 完全一致(`hash` = 整个文件的 sha256,`created_at` = journal 的
|
||||
`when`),而 migrator 只比 `created_at`、不校验 hash,所以两套执行器可以互换,不会看不懂
|
||||
对方写的记录。
|
||||
|
||||
**`CREATE INDEX CONCURRENTLY` 现在能跑了。** 在迁移文件**第一行**写上标记:
|
||||
|
||||
```sql
|
||||
-- oj2:no-transaction
|
||||
CREATE INDEX CONCURRENTLY "xxx_idx" ON "submission" USING btree ("language");
|
||||
```
|
||||
|
||||
这条迁移就走裸执行(简单查询协议,不包事务)。代价是**没有回滚**:中途失败时前面的语句
|
||||
已经生效,而且 CONCURRENTLY 失败会在库里留下一个 INVALID 索引,要先
|
||||
`DROP INDEX` 再重来(`select indexrelid::regclass from pg_index where not indisvalid`
|
||||
能找出来)。所以**这种迁移一个文件只放一条语句**。
|
||||
|
||||
要不要用是另一回事:参考量级是 12.3 万行的部分索引,普通 `CREATE INDEX` 只锁 74ms,
|
||||
一般不用纠结,CONCURRENTLY 留给真扛不住锁写窗口的场合。
|
||||
|
||||
退出码:2 = 配置/文件问题,3 = 基线不对,4 = 撞上破坏性迁移,5 = 某条迁移执行失败。

|
||||
设它,会静默起一套空数据(空库、没测试点、图片 404),而且**不报错** —— 这是整个部署里
|
||||
唯一会静默走歪的地方,`deploy.sh` 为它专门设了一道自检。
|
||||
- **只换前后端**(上线用这个):设 `DATA_DIR` / `DB_HOST` / `REDIS_HOST`,
|
||||
沿用旧栈已经在跑的 postgres 和 redis,只起 api / worker / web / judge。
|
||||
- **自带数据**(本机、演练):不设那几个变量,起栈时加 `--profile local-data`。
|
||||
- **并行试跑**(上线前先挂 `oj2.xuyue.cc` 跑几天):在「只换前后端」基础上再加
|
||||
`WEB_PORT`(8080 被旧 backend 占着)和 `JUDGE_STATE_DIR`(两个判题机不能共用运行目录)。
|
||||
这种形态下旧栈一个容器都不用停,正式切换退化成改一行 NPM 上游。

# CLAUDE.md
|

|
||||
OJ2 的后端(`apps/api`)。这里只放后端专属的坑;全仓通用的约束(旧仓库冻结、判题状态码、
|
||||
时间锚点、判题镜像、部署)在 `../../CLAUDE.md`。
|
||||
|
||||
## 单二进制是有代价的
|
||||
|
||||
`apps/api` 编译成 `bun build --compile` 的单二进制,所以**运行时不能依赖 node_modules**。
|
||||
任何 `require.resolve` / `Bun.resolveSync` / `__dirname` 去找文件的写法,本地都正常、编译后
|
||||
都会炸,而且**只在离开仓库目录后才炸**(在仓库里跑时它顺着 cwd 摸到了 node_modules,
|
||||
假装没事)。
|
||||
|
||||
资源要用 `with { type: "file" }` 内嵌。`.node` 原生模块还要额外注意:这个写法只有打包器认、
|
||||
`bun run` 不认,所以必须按形态分叉 —— 见 `src/vendor/jieba.ts` 的注释,那里把坑写全了。
|
||||
|
||||
**改完这类代码,dev 和编译两种形态都要跑一遍。** 我吃过亏:只验了编译产物,dev 直接起不来。
|
||||
|
||||
`build` 带 `--bytecode --format=esm`:每道 SQL 题都要起一次 `sql-child`,预编译字节码让它
|
||||
从约 120ms 降到约 72ms(单核实测),`serve` 起服务从约 180ms 降到约 100ms,内存不变,
|
||||
代价是二进制大 8MB。去掉 `--format=esm` 会退回 CJS 输出,顶层 await 编不过。
|
||||
|
||||
## 路径解析看 `runtime.ts`
|
||||
|
||||
编译后 `import.meta.dir` 恒为 `/$bunfs/root`,往上三级就是文件系统根。
|
||||
相对路径一律走 `runtime.ts` 的 `pathBase`,别自己拼。
|
||||
|
||||
## SQL 判题会 spawn「自己」
|
||||
|
||||
`judge/sql/index.ts` 起的子进程是二进制自身 + `sql-child` 子命令(因为编译后磁盘上没有
|
||||
child.ts 可以 spawn)。所以**入口必须有 argv 分发**,否则「起自己」变成「把整个程序再跑
|
||||
一遍」→ 指数级 fork。这不是假想,开发时炸过一次开发机。`OJ2_SQL_CHILD` 那道递归闸不要删。
|
||||
|
||||
## 加路由要防遮蔽
|
||||
|
||||
**Hono 按注册顺序匹配,不是静态优先**(实测确认过,别凭直觉)。`/problems/:id` 注册在
|
||||
`/problems/random` 前面的话,后者永远进不去 —— 而且不报错、不警告,只是静默走进前一条的
|
||||
handler。阶段 4 真实发生过一次,两个教师用的分析端点被吃掉,一直到评审才发现。
|
||||
|
||||
加完路由跑 `bun run --filter '@oj2/api' check:routes`。
|
||||
|
||||
## 出参不 `parse`,用 `satisfies`
|
||||
|
||||
**后端的响应一律 `satisfies XxxType`,不要写 `xxxSchema.parse({...})`。** 出参是后端自己刚
|
||||
拼出来的字面量,TS 已经在编译期校验过;再 parse 一遍拿不到任何新信息,唯一可能失败的输入是
|
||||
**库里的历史数据**,而失败的代价是 500 —— 这条规矩是被四次这样的线上故障换来的。
|
||||
|
||||
**闸设在写入侧**:入参 `safeParse`、`db/schema.ts` 的 `.$type<>()` 列收窄、
|
||||
语义校验函数(`astRulesError()` / `exerciseDataError`)。JSONB 原文
|
||||
(`submission.info` / `statistic_info` / `exercise.data`)一律放行,它们的形状真相在判题机
|
||||
那边。query 的筛选值走 `routes/helpers.ts` 的 `asFilterValue()`,那是纯类型交接、不加校验。
|
||||
|
||||
四次故障的细节、`.$type<>()` 断言该怎么核,见 `../../docs/contract.md`;
|
||||
前端为什么只在三处挂运行时闸门,见 `../web/CLAUDE.md`。

||||
|
||||
## 数据库
|
||||
|
||||
Drizzle schema 最初是 `drizzle-kit pull` 从生产库拉出来的,所以它长得像 Django 建的表
|
||||
(表名、bigint/int4 混用),`schema.ts` 顶部记了哪些地方是手工修的。
|
||||
**schema 现在归 OJ2 独占**,结构变更走 migration 正常演进。
|
||||
|
||||
**外键的删除动作从 0010 起是显式的**,不再是 Django 留下的一律 NO ACTION:
|
||||
|
||||
- **CASCADE**:父行消失后子行必然无意义、且不构成「学生做过什么」的证据 —— 中间表
|
||||
(problem_tags)、专题/教程/成就的组成部分、一对一附属(user_profile)与可重算的缓存
|
||||
(user_stat)。
|
||||
- **NO ACTION(即拦住)**:需要人看见的删除 —— `submission.problem_id`、以及 `user` 的绝大
|
||||
多数外键。删用户撞外键会被 handler 翻译成「请改为禁用账号」,这是有意的。
|
||||
|
||||
**加新子表时必须回来想一遍该走哪一档**,别默认新外键会自己连坐 —— drizzle 不写
|
||||
`.onDelete()` 就是 NO ACTION,而 0010 只改了当时存在的那批。
|
||||
|
||||
### 改 schema 走 drizzle migration
|
||||
|
||||
`bun run db:generate`(造迁移文件)→ `bun run db:migrate`(按
|
||||
`drizzle.__drizzle_migrations` 增量执行),就是 Django `makemigrations` / `migrate` 的
|
||||
等价物。索引/结构变更走这条,不要再手写 SQL 往 `docs/` 里塞。
|
||||
|
||||
- **部署时自动执行**:`docker/deploy.sh` 在构建镜像之后、起栈之前跑,失败就中止部署。

`TRUNCATE`),退出 4,要显式放行:`OJ2_ALLOW_DESTRUCTIVE=1 docker/deploy.sh`。

|
||||
|
||||
- 逐框照字面翻,学生写错了就照错的翻,**不要替他改正、补全或者合并**;框里没写的事不要做。
|
||||
- 输入框:读数据的语句。按例子的输入格式读(一行一个就一个 input(),一行几个就 split),看得出是数就转成 int 或 float。框里写了几个变量就读几个。
|
||||
- 处理框:赋值之类的语句,可以有几行。
|
||||
- 输出框:**一个表达式**,它的值就是这个框输出的那一行。框里是没写变量的文字就当字符串原样输出(开头的「输出」两个字不算)。
|
||||
变量后面跟着的文字直接拼在后面:「输出 等级,降级处理」是 f"{等级},降级处理" —— 中文逗号「,」是要输出的字,不是分隔符。
|
||||
写了保留几位小数就用 f-string 格式化。
|
||||
- 判断框、循环的条件:一个条件表达式,不带 if / while,不带冒号。
|
||||
- 变量名:框里的中文名可以直接当变量名。同一个东西在不同框里写法不同(「直径」「直径 d」「d」)时用同一个名字。
|
||||
- 看不懂、或者框里只是占位的字(「条件」「做什么」「(空)」),给 null。
|
||||
|
||||
另外给 style:图里真有毛病才写一句建议给学生 —— 多余的框、看不出在判断什么的条件、输出框没写清楚输出什么。
|

不要提 Python,不要写框的编号,提到框用框里的字加「」。措辞上能更好、但不影响看懂的不算毛病,给空字符串;大多数图都应该是空字符串。

|

* 判题沙箱(go-judge,见 docker/judge/)的客户端:编译、逐个测试点运行、比对输出、定状态码。
|
||||
*
|
||||
* go-judge 只管「在沙箱里跑一条命令、量出用了多少」,判题流程是这里拼起来的。2026-10 之前
|
||||
* 判题机是 QingdaoU/JudgeServer,流程在它的 judge_client.py 里;这里是**逐条照搬**它的
|
||||
* 口径,出参也保持它的形状(`{ err, data: JudgeCase[] }`、每个点的 cpu_time / memory /
|
||||
* signal / exit_code …)—— 12 万条历史提交的 `info` 就是这个形状,前端和统计都按它读。
|
||||
* 换过来时拿生产库的真实提交逐份对比过新旧两边的判定,结论见 docker/judge/README.md。
|
||||
*
|
||||
* 照搬的口径:
|
||||
* - **输出比对**:整段输出 rstrip(只剥 ASCII 空白,和 Python 的 bytes.rstrip 一样)后取
|
||||
* md5,和测试点 info 里的 `stripped_output_md5` 比。
|
||||
* - **stdout 和 stderr 合在一起比**:JudgeServer 把两者重定向到同一个文件。Python 的
|
||||
* SyntaxWarning、C 往 stderr 打的东西都算进输出,所以这里两个 fd 接同一个收集器。
|
||||
* - **内存**:地址空间限到题目内存的两倍(RLIMIT_AS),跑完峰值超过题目内存判超限。
|
||||
* malloc 先成功一阵、到两倍才失败,所以内存爆了多半判「内存超限」而不是运行时错误。
|
||||
* - **输出上限 16MB**(镜像的 -output-limit):死循环打印写满吃 SIGXFSZ,判运行时错误、
|
||||
* 信号 25,前端对它有专门的中文说明。
|
||||
* - **墙钟是 CPU 时限的 3 倍**;状态码的先后顺序照 libjudger 的 runner.c,见 verdict()。
|
||||
*
|
||||
* 和 JudgeServer 不一样的地方(都是沙箱换了带来的,判定上只会更宽松):
|
||||
* - 学生程序不能再开进程或线程(procLimit 1)。原来是 seccomp 直接杀,信号 31;现在
|
||||
* fork 失败、system("pause") 返回 -1,程序照样往下跑。
|
||||
* - 内存读数是 cgroup 的峰值,比原来的 ru_maxrss 小(C 的空程序 0.25MB,原来 1.5MB)。
|
||||
* - CPU 时间含内核态,原来只算用户态。
