CJACK 6959aa2982 feat: add ETag cache optimization, code-split WebUI, and refactor XML tool scanner
- Chat history: early 304 via Revision()/DetailRevision() to avoid full snapshot reads
- WebUI: lazy-load tab containers with Suspense fallback
- Toolstream: split tool_sieve_xml.go into tags.go and scan.go
- CI: trigger on main branch, guard cross-build to dev/main pushes only
- Docs: add DEVELOPER.md developer quick reference

# DS2API 开发者速查
语言 / Language: 中文
本文面向维护者和贡献者,用于快速判断“从哪里看、改哪里、跑什么”。架构细节仍以 [ARCHITECTURE.md](./ARCHITECTURE.md) 为准,接口行为以 [API.md](../API.md) 为准。
## 1. 本地入口
常用启动与检查:
```bash
# 后端
go run ./cmd/ds2api
# WebUI 开发服务器
npm run dev --prefix webui
# WebUI 生产构建
npm run build --prefix webui
```
PR 前固定门禁:
```bash
./scripts/lint.sh
./tests/scripts/check-refactor-line-gate.sh
./tests/scripts/run-unit-all.sh
npm run build --prefix webui
```
修改 Go 文件后先运行:
```bash
gofmt -w <changed-go-files>
```
## 2. 代码定位
优先从这些入口顺着调用链看:
| 目标 | 入口 |
| --- | --- |
| 总路由、CORS、健康检查 | `internal/server/router.go` |
| OpenAI Chat / Responses | `internal/httpapi/openai/chat``internal/httpapi/openai/responses` |
| Claude / Gemini 兼容入口 | `internal/httpapi/claude``internal/httpapi/gemini` |
| API 请求归一到网页纯文本上下文 | `internal/promptcompat``docs/prompt-compatibility.md` |
| 工具调用解析与流式防泄漏 | `internal/toolcall``internal/toolstream``docs/toolcall-semantics.md` |
| DeepSeek 上游调用、登录、PoW、代理 | `internal/deepseek/client``internal/deepseek/transport` |
| 账号池、并发槽位、等待队列 | `internal/account` |
| Admin API | `internal/httpapi/admin` |
| WebUI 页面 | `webui/src/layout/DashboardShell.jsx``webui/src/features/*` |
| 服务器端对话记录 | `internal/chathistory``internal/httpapi/admin/history` |
## 3. 常见改动建议
- 改接口行为时,同时检查 `API.md` / `API.en.md` 是否需要同步。
- 改 prompt 兼容链路时,必须同步 `docs/prompt-compatibility.md`
- 改 tool call 语义时,同时检查 Go、Node sieve 和 `docs/toolcall-semantics.md`
- 改 WebUI 配置项时,同时检查 `webui/src/features/settings`、语言包和 `config.example.json`
- 拆分大文件时,保持对外函数签名稳定,并跑 `./tests/scripts/check-refactor-line-gate.sh`
## 4. 故障定位
接口请求先看路由入口,再看协议适配层,最后看共享 runtime
1. 路由是否命中:`internal/server/router.go` 和对应 `RegisterRoutes`
2. 鉴权与账号选择:`internal/auth``internal/account`
3. 请求归一化:`internal/promptcompat` 或协议转换包。
4. 上游请求:`internal/deepseek/client`
5. 流式输出:`internal/stream``internal/sse``internal/toolstream`
6. 响应格式:`internal/format/*``internal/translatorcliproxy`
对话记录页面问题优先检查:
- Admin API`/admin/chat-history``/admin/chat-history/{id}`
- 后端存储:`internal/chathistory/store.go`
- 前端轮询和 ETag`webui/src/features/chatHistory/ChatHistoryContainer.jsx`
Tool call 问题优先跑:
```bash
go test -v ./internal/toolcall ./internal/toolstream -count=1
node --test tests/node/stream-tool-sieve.test.js tests/node/chat-stream.test.js
```
## 5. 测试选择
小范围 Go 改动:
```bash
go test ./internal/<package> -count=1
```
前端改动:
```bash
npm run build --prefix webui
```
高风险协议或流式改动:
```bash
./tests/scripts/run-unit-all.sh
```
发布或真实账号链路验证:
```bash
./tests/scripts/run-live.sh
```
端到端测试产物默认写入 `artifacts/testsuite/`。分享日志前需要清理 token、密码、cookie 和原始请求响应内容。
