Implementation Plan: 配置与骨架
Branch: 001-config-bootstrap | Date: 2025-11-13 | Spec: spec.md
Input: Feature specification from /specs/001-config-bootstrap/spec.md
Note: This template is filled in by the /speckit.plan command. See .specify/templates/commands/plan.md for the execution workflow.
Summary
Phase 0 delivers a reliable bootstrap for any-hub: a validated internal/config loader with defaults/tests, a CLI entry (cmd/any-hub) that accepts --config, --check-config, --version, and a Logrus + Lumberjack logging stack that honors config-provided level/output. The approach is to codify the configuration schema (global + [[Hub]]), implement strict validation with helpful errors, ensure CLI paths separate validation vs. runtime, and guarantee consistent structured logging for both success and failure flows.
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> + .meta 元数据
Testing: go test ./...,使用 httptest、临时目录和自建上游伪服务验证配置/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 配置控制;每个 Hub 需独立 Domain/Port 绑定;仅匿名访问
Scale/Scope: 支撑 Docker/NPM/Go/PyPI 等多仓代理,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 聚焦“轻量、匿名、CLI 多仓代理”,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(Fiber/Viper/Logrus/Lumberjack + 标准库);无新增第三方库需求。
- 行为完全由
config.toml控制,计划中定义所有默认值、优先级(标志 > 环境变量 > 默认)、以及迁移策略。 - CLI 与配置实现维持缓存优先 + 流式回源的大前提,并输出命中/回源/失败日志字段,满足可观测原则。
- 计划明确覆盖配置解析、必填字段校验、Host Header 约束、中文注释与
go test需求,满足测试 Gate。
Post-design re-check (Phase 1): 设计阶段确认各文档与合同未偏离宪法约束,仍无新增依赖、UI 或多配置源,GATE 维持通过。

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。
