# Implementation Plan: Module Hook Refactor
|
||
|
||
**Branch**: `006-module-hook-refactor` | **Date**: 2025-11-17 | **Spec**: specs/006-module-hook-refactor/spec.md
|
||
**Input**: Feature specification from `/specs/006-module-hook-refactor/spec.md`
|
||
|
||
**Note**: This file captures planning up to Phase 2 (tasks generated separately).
|
||
|
||
## Summary
|
||
|
||
目标:让每个 hubmodule 完整自管缓存/代理逻辑(路径重写、缓存策略、上游解析、响应重写等),proxy handler 仅负责调度、缓存读写及统一日志/错误包装。技术路线:\n1. 定义 Hook/Handler 契约与注册机制。\n2. 将 Docker/NPM/PyPI/Composer/Go 的特化逻辑迁移到各自 Hook。\n3. legacy handler 仅做兜底;proxy handler 移除所有 `hub_type` 分支并加强错误观测。
|
||
|
||
## Technical Context
|
||
|
||
**Language/Version**: Go 1.25+ (静态链接,单二进制交付)
|
||
**Primary Dependencies**: Fiber v3(HTTP 服务)、Viper(配置)、Logrus + Lumberjack(结构化日志 & 滚动)、标准库 `net/http`/`io`
|
||
**Storage**: 本地文件系统缓存目录 `StoragePath/<Hub>/<path>`(由模块 Hook 定义布局)
|
||
**Testing**: `go test ./...`,使用 `httptest`、临时目录与模块 Hook 示例验证缓存/代理路径
|
||
**Target Platform**: Linux/Unix CLI 进程,由 systemd/supervisor 管理,匿名下游客户端
|
||
**Project Type**: 单 Go 项目(`cmd/` 入口 + `internal/*` 包)
|
||
**Performance Goals**: 缓存命中直接返回;回源路径需流式转发,单请求常驻内存 <256MB;命中/回源日志可追踪
|
||
**Constraints**: 禁止 Web UI 或账号体系;所有行为受单一 TOML 控制;每个 Hub 需独立 Domain 绑定;仅匿名访问
|
||
**Scale/Scope**: 支撑 Docker/NPM/Go/PyPI/Composer,多仓 Hook 自治,面向弱网及离线缓存复用场景
|
||
|
||
## Constitution Check
|
||
|
||
*GATE: Must pass before Phase 0 research. Re-check after Phase 1 design.*
|
||
|
||
- Feature 仍然是“轻量多仓 CLI 代理”,未引入 Web UI、账号体系或与代理无关的能力。
|
||
- 仅使用 Go + 宪法指定依赖;任何新第三方库都已在本计划中说明理由与审核结论。
|
||
- 行为完全由 `config.toml` 控制,新增配置项已规划默认值、校验与迁移策略。
|
||
- 方案维持缓存优先 + 流式回源路径,并给出命中/回源/失败的日志与观测手段。
|
||
- 计划内列出了配置解析、缓存读写、Host Header 路由等强制测试与中文注释交付范围。

### Source Code (repository root)

```text

cmd/any-hub/main.go # CLI 入口、参数解析
|
||
internal/config/ # TOML 加载、默认值、校验
|
||
internal/server/ # Fiber 服务、路由、中间件
|
||
internal/cache/ # 磁盘/内存缓存与 .meta 管理
|
||
internal/proxy/ # 上游访问、缓存策略、流式复制
|
||
configs/ # 示例 config.toml(如需)
|
||
tests/ # `go test` 下的单元/集成测试,用临时目录
|
||
```
|
||
|
||
**Structure Decision**: 采用单 Go 项目结构,特性代码应放入上述现有目录;如需新增包或目录,必须解释其与 `internal/*` 的关系并给出后续维护策略。
