name: Launcher 单项目解耦
|
||||
overview: 在保持单一 LanMountainDesktop.Launcher 项目、单一 exe、零部署风险的前提下，按职责域增量重构：目录分层、RunAsync→Pipeline+Phase、UpdateEngine→策略类、App→纯 Avalonia+LauncherOrchestrator；执行过程中由 Agent 自主 Git 提交，每域可编译可测。

# Launcher 单项目内部解耦改造计划（执行版）
|
||||
|
||||
## 0. 硬性约束
|
||||
|
||||
|
||||
| 约束 | 说明 |
|
||||
| ------------ | --------------------------------------------------------------------------------------------------------------------------------------------------------- |
|
||||
| **单项目** | 仅 `[LanMountainDesktop.Launcher/LanMountainDesktop.Launcher.csproj](LanMountainDesktop.Launcher/LanMountainDesktop.Launcher.csproj)`，不新建 Launcher.* 独立程序集 |
|
||||
| **单 exe** | 仍只发布 `LanMountainDesktop.Launcher.exe`（AOT 单文件） |
|
||||
| **零部署风险** | 不改变安装包目录结构、不引入新进程、不改变 Public IPC / Coordinator IPC 拓扑与契约 |
|
||||
| **增量重构** | 一个职责域一域推进，每步 `dotnet build` + 相关 `dotnet test` 通过后再进下一步 |
|
||||
| **单进程性能** | 模块间仅 in-process 接口调用，不为解耦新增 IPC |
|
||||
| **未来可拆** | 各域暴露 `I`* 接口，将来若需多进程可直接复用契约 |
|
||||
| **Git 自主提交** | Agent 在每个职责域完成且验证通过后 **自动 commit**，无需用户手动提交（见 §8） |
|
||||
|
||||
|
||||
外部共享库 `[LanMountainDesktop.PluginPackaging](LanMountainDesktop.PluginPackaging/)` 保留（Host + Launcher CLI 共用），不属于 Launcher 拆分。
|
||||
|
||||
---
|
||||
|
||||
## 1. 验收标准（必须全部满足）
|
||||
|
||||
### 1.1 零部署风险
|
||||
|
||||
- Inno Setup / CI 产物仍只有：`LanMountainDesktop.Launcher.exe` + `app-{version}/` + `.launcher/`
|
||||
- Host 调用 Launcher 的 CLI 参数、`launch-source`、`apply-update` 路径不变
|
||||
- Public IPC routes（`lanmountain.launcher.startup-progress`、`loading-state`）与 Coordinator pipe 不变
|
||||
- VeloPack / 更新 apply 状态机（`.current/.partial/.destroy`）行为不变
|
||||
|
||||
### 1.2 增量可验证
|
||||
|
||||
- 每个 Phase 结束：编译绿 + 该域新增/既有测试绿
|
||||
- 允许「纯移动文件」的 PR 单独提交，行为 diff 为零
|
||||
|
||||
### 1.3 测试友好
|
||||
|
||||
- `Startup/`、`Update/`、`Deployment/` 内类型 **无 Avalonia 依赖**，可独立单元测试
|
||||
- 每个 `ILaunchPhase`、每个 Update 策略类各有对应测试类
|
||||
- 保留并扩展现有 `[LauncherStartupTimeoutPolicyTests](LanMountainDesktop.Tests/LauncherStartupTimeoutPolicyTests.cs)`、`[LauncherMultiInstancePolicyTests](LanMountainDesktop.Tests/LauncherMultiInstancePolicyTests.cs)`
|
||||
|
||||
### 1.4 启动性能
|
||||
|
||||
- Pipeline 阶段为同步/异步方法调用链，不引入额外进程或网络
|
||||
- DI 容器仅在进程入口构建一次；Stage/Phase 实例可复用 Singleton
|
||||
|
||||
### 1.5 代码结构目标
|
||||
|
||||
|
||||
| 对象 | 当前（实测） | 目标 |
|
||||
| ----------------------------------- | -------------------------------------------- | --------------------------------------------------- |
|
||||
| `LauncherFlowCoordinator` 全 partial | ~1880 行（859+568+279+…） | **删除**；逻辑迁入 Pipeline + Phases |
|
||||
| `RunAsync()` 等价逻辑 | 跨 partial ~800+ 行 while/阶段混杂 | **≤80 行** 编排入口，细节在各 Phase |
|
||||
| `UpdateEngineService` | ~1622 行 | 门面 **≤200 行** + 6 个策略类各 **≤300 行** |
|
||||
| `App.axaml.cs` | ~258 行（已部分瘦身） | **≤120 行**：纯 Avalonia + 一行委托 `LauncherOrchestrator` |
|
||||
| `LauncherOrchestrator` | 不存在（逻辑在 Coordinator + CompositionRoot 546 行） | **≤250 行**：GUI 入口编排 |
|
||||
| `LauncherCompositionRoot` | ~546 行 | **≤150 行**：仅 DI 构建 + 入口分发 |
|
||||
|
||||
|
||||

|
||||
|
||||
## 2. 目标架构
|
||||
|
||||
### 2.1 核心类型关系
|
||||
|
||||

LauncherCompositionRoot --> ServiceProvider
|
||||
ServiceProvider --> LaunchPipeline
|
||||
```
|
||||
|
||||
|
||||
|
||||
**命名约定：**
|
||||
|
||||
- `**LauncherOrchestrator`**：GUI 生命周期内的唯一编排入口（取代 `LauncherFlowCoordinator` 对外角色）
|
||||
- `**LaunchPipeline**`：按序执行 `ILaunchPhase` 列表
|
||||
- `**ILaunchPhase**`：原 `ILaunchPipelineStage`；每个 Phase 对应原 `RunAsync` 中一个职责段
|
||||
|
||||
### 2.2 职责域目录（单项目内）
|
||||
|

|
||||
|
||||
### 2.3 模块依赖规则
|
||||
|
||||
- `Deployment/`、`Update/`、`Startup/`：**禁止** `using Avalonia`
|
||||
- `Views/`：**禁止** 引用具体 `UpdateEngineFacade` / `DeploymentLocator`（仅接口或 Orchestrator）
|
||||
- 跨域：**仅通过 `I`* 接口**；Orchestrator/Pipeline 负责装配
|
||||
|
||||
### 2.4 与 Host 边界（不变）
|
||||
|
||||
|
||||
| 能力 | Owner |
|
||||
| -------------------------- | ------------------------------ |
|
||||
| OOBE / Splash / 多实例 / 启动检测 | Launcher `Startup/` + `Shell/` |
|
||||
| 更新 apply / rollback | Launcher `Update/` |
|
||||
| 插件市场 / pending | Host + PluginPackaging |
|
||||
| 更新 download | Host → spawn Launcher apply |
|
||||
|
||||
|
||||
---
|
||||
|
||||
## 3. 三大核心拆分（用户指定）
|
||||
|
||||
### 3.1 拆分 `LauncherFlowCoordinator`：`RunAsync` → Pipeline + Phase
|
||||
|
||||
**现状：** 逻辑分散在 4 个 partial，等效一个 1800+ 行 God Class；`RunAsync` 内含清理、OOBE、更新、启动、IPC 监听、超时 while-loop、多实例分支。
|
||||
|
||||
**目标 API（单项目 `Shell/` 内）：**
|
||||
|
||||
```csharp
|
||||
internal interface ILaunchPhase
|
||||
{
|
||||
string PhaseId { get; }
|
||||
/// <returns>null = 继续下一阶段；非 null = 管道终止并返回结果</returns>
|
||||
Task<LauncherResult?> ExecuteAsync(LaunchContext context, CancellationToken cancellationToken);
|
||||
}
|
||||
|
||||
internal sealed class LaunchPipeline
|
||||
{
|
||||
public LaunchPipeline(IEnumerable<ILaunchPhase> phases) { ... }
|
||||
public Task<LauncherResult> RunAsync(LaunchContext context, CancellationToken ct);
|
||||
}
|
||||
```
|
||||
|
||||
**Phase 映射（与原 RunAsync 步骤一一对应）：**
|
||||
|
||||
|
||||
| Phase | 原 RunAsync 段 | 产出 |
|
||||
| ------------------------- | --------------------------------------- | ----------------------------- |
|
||||
| `CleanupDeploymentsPhase` | `CleanupOldDeployments` | 无 UI |
|
||||
| `ExistingHostProbePhase` | 多实例 / Public IPC 探测 | 可短路成功 |
|
||||
| `ApplyPendingUpdatePhase` | `_updateEngine.ApplyPendingUpdateAsync` | 失败仍继续 |
|
||||
| `OobeGatePhase` | migration + OOBE steps | UI via `ILauncherUiPresenter` |
|
||||
| `LaunchHostPhase` | `LaunchHostWithIpcAsync` | Process + plan |
|
||||
| `MonitorStartupPhase` | while-loop + IPC + timeout | 调用 `IHostStartupMonitor` |
|
||||
|
||||
|
||||
`**LauncherOrchestrator` 职责：**
|
||||
|
||||
- 接收 `SplashWindow`、构建 `LaunchContext`（含 reporter、attempt registry、coordinator server）
|
||||
- 调用 `LaunchPipeline.RunAsync`
|
||||
- 管理 Splash/Error 窗口生命周期（委托 `ILauncherUiPresenter`）
|
||||
- **不含** 更新/部署/IPC 细节
|
||||
|
||||
**删除清单：** `LauncherFlowCoordinator.cs` 及全部 partial 文件。
|
||||
|
||||
---
|
||||
|
||||
### 3.2 拆分 `UpdateEngineService` → 门面 + 策略类
|
||||
|
||||
**现状：** ~1622 行单文件，混合检测、验签、解压、激活、快照、回滚、清理。
|
||||
|
||||
**目标结构：**
|
||||
|
||||
```
|
||||
Update/
|
||||
├── IUpdateEngine.cs # 对外契约（未来多进程可原样抽出）
|
||||
├── UpdateEngineFacade.cs # 门面，编排策略，≤200 行
|
||||
└── Strategies/
|
||||
├── IUpdateStrategy.cs # 可选：各策略统一接口
|
||||
├── PendingUpdateDetector.cs # CheckPendingUpdate
|
||||
├── UpdatePackageVerifier.cs # manifest + RSA 签名
|
||||
├── UpdatePackageExtractor.cs # 解压 / 增量复用
|
||||
├── DeploymentActivator.cs # .current / .partial / .destroy
|
||||
├── UpdateSnapshotStore.cs # snapshots 读写
|
||||
├── RollbackStrategy.cs # rollback CLI/GUI
|
||||
└── IncomingArtifactsCleaner.cs # CleanupIncomingArtifacts
|
||||
```
|
||||
|
||||
**门面方法映射：**
|
||||
|
||||
|
||||
| 原 `UpdateEngineService` 公开方法 | 委托策略 |
|
||||
| ---------------------------- | ------------------------------------------------------ |
|
||||
| `CheckPendingUpdate()` | `PendingUpdateDetector` |
|
||||
| `ApplyPendingUpdateAsync()` | Detector → Verifier → Extractor → Activator → Snapshot |
|
||||
| `RollbackLatest()` | `RollbackStrategy` |
|
||||
| `CleanupIncomingArtifacts()` | `IncomingArtifactsCleaner` |
|
||||
| `DownloadAsync()`（若有） | 保持或拆 `UpdateDownloader` |
|
||||
|
||||
|
||||
**测试：** 每个 Strategy 独立 mock `IDeploymentLocator` / 文件系统，不启 Avalonia。
|
||||
|
||||
---
|
||||
|
||||
### 3.3 精简 `App.axaml.cs` → 纯 Avalonia + `LauncherOrchestrator`
|
||||
|
||||
**现状：** ~258 行，仍含 apply-update、air-app-broker、preview、coordinator attach 等分支。
|
||||
|
||||
**目标结构：**
|
||||
|
||||
```csharp
|
||||
// App.axaml.cs 目标形态（概念）
|
||||
public override void OnFrameworkInitializationCompleted()
|
||||
{
|
||||
if (ApplicationLifetime is IClassicDesktopStyleApplicationLifetime desktop)
|
||||
{
|
||||
var context = LauncherRuntimeContext.Current;
|
||||
var mode = LauncherEntryModeResolver.Resolve(context);
|
||||
_ = LauncherOrchestrator.RunAsync(desktop, context, mode);
|
||||
}
|
||||
base.OnFrameworkInitializationCompleted();
|
||||
}
|
||||
```
|
||||
|
||||
**从 App 迁出的逻辑 → `Shell/EntryHandlers/`：**
|
||||
|
||||
|
||||
| 现 App 分支 | 新 Handler |
|
||||
| ----------------- | -------------------------------------- |
|
||||
| `launch` + splash | `GuiLaunchEntryHandler` → Orchestrator |
|
||||
| `apply-update` | `ApplyUpdateEntryHandler` |
|
||||
| `air-app-broker` | `AirAppBrokerEntryHandler` |
|
||||
| debug preview | `PreviewEntryHandler` |
|
||||
|
||||
|
||||
**验收：** `App.axaml.cs` ≤120 行；不含 `new UpdateEngineService` / `new DeploymentLocator` / while-loop。
|
||||
|

|
||||
|
||||
## 4. 分阶段执行顺序与 Git 提交点
|
||||
|
||||
```mermaid
|
||||
flowchart LR
|
||||
A[Phase A Startup] --> B1[Phase B1 目录迁移]
|
||||
B1 --> B2[Phase B2 Pipeline+Orchestrator]
|
||||
B2 --> B3[Phase B3 App 精简]
|
||||
B3 --> C[Phase C DI]
|
||||
B1 --> D[Phase D Update 策略拆分]
|
||||
C --> E[Phase E 守卫+文档+AOT回归]
|
||||
D --> E
|
||||
```
|
||||
|
||||
|
||||
|
||||
### Phase A：Startup 子系统 + AOT 生产 bug（优先）
|
||||
|
||||
- 抽出 `Startup/HostStartupMonitor.cs`（从 partial 独立）
|
||||
- 修复 IPC 连接退避、成功判定统一走 `StartupSuccessTracker`
|
||||
- Host 侧 `DesktopVisible` 上报对齐（仅日志/时序，不改 IPC 契约）
|
||||
- 测试 + `**git commit**`: `fix(launcher): extract HostStartupMonitor and harden startup detection`
|
||||
|
||||
### Phase B1：目录迁移（零逻辑变更）
|
||||
|
||||
- 物理移动文件到 `Deployment/`、`Update/`、`Startup/` 等，更新 namespace
|
||||
- `dotnet build` + test
|
||||
- `**git commit**`: `refactor(launcher): reorganize into responsibility folders`
|
||||
|
||||
### Phase B2：Pipeline + Phase + LauncherOrchestrator
|
||||
|
||||
- 实现 `ILaunchPhase`、`LaunchPipeline`、`LauncherOrchestrator`
|
||||
- 逐 Phase 从 Coordinator 迁移逻辑（可先并行运行对照测试）
|
||||
- 删除 `LauncherFlowCoordinator*`
|
||||
- `**git commit**`: `refactor(launcher): replace LauncherFlowCoordinator with LaunchPipeline`
|
||||
|
||||
### Phase B3：App.axaml.cs 精简
|
||||
|
||||
- EntryHandlers 提取；App 仅 Avalonia + Orchestrator 委托
|
||||
- `**git commit**`: `refactor(launcher): slim App.axaml.cs to Avalonia shell only`
|
||||
|
||||
### Phase C：轻量 DI
|
||||
|
||||
- `LauncherServiceRegistration.cs` + `Microsoft.Extensions.DependencyInjection`
|
||||
- Program / CliHost / CompositionRoot 统一 `ServiceProvider`
|
||||
- `**git commit**`: `refactor(launcher): add composition-root DI wiring`
|
||||
|
||||
### Phase D：UpdateEngine 策略拆分（可与 B2 并行，依赖 B1）
|
||||
|
||||
- 策略类提取 + `UpdateEngineFacade`
|
||||
- 删除原巨型 `UpdateEngineService.cs`
|
||||
- 每策略测试
|
||||
- `**git commit**`: `refactor(launcher): split UpdateEngine into strategy classes`
|
||||
|
||||
### Phase E：守卫 + 文档 + AOT 回归
|
||||
|
||||
- `LauncherArchitectureTests`（命名空间依赖规则）
|
||||
- 更新 `[docs/LAUNCHER.md](docs/LAUNCHER.md)`、`[.trae/specs/launcher-shell-hardening/spec.md](.trae/specs/launcher-shell-hardening/spec.md)`
|
||||
- AOT publish 本地 smoke：launch / apply-update / 多实例 / 启动检测
|
||||
- `**git commit**`: `docs(launcher): document module boundaries and add architecture tests`
|
||||
|
||||
---
|
||||
|
||||
## 5. Phase / Service 测试矩阵
|
||||
|
||||
|
||||
| 组件 | 测试文件 | 覆盖点 |
|
||||
| ----------------------- | ---------------------------- | --------------------------------- |
|
||||
| `StartupSuccessTracker` | `StartupSuccessTrackerTests` | Foreground/Tray/Background policy |
|
||||
| `HostStartupMonitor` | `HostStartupMonitorTests` | 超时、IPC 延迟、ShellStatus 轮询 |
|
||||
| `LaunchPipeline` | `LaunchPipelineTests` | Phase 短路、失败传播 |
|
||||
| 各 `ILaunchPhase` | `*PhaseTests` | 单阶段 mock |
|
||||
| `PendingUpdateDetector` | `PendingUpdateDetectorTests` | 无 pending / corrupt |
|
||||
| `DeploymentActivator` | `DeploymentActivatorTests` | 标记文件状态机 |
|
||||
| `RollbackStrategy` | `RollbackStrategyTests` | 快照回退 |
|
||||
| 命名空间规则 | `LauncherArchitectureTests` | 无 Avalonia 泄漏 |
|
||||
|
||||
|
||||
---
|
||||
|
||||
## 6. 明确不做
|
||||
|
||||
- 不新建 csproj（Launcher.Deployment 等）
|
||||
- 不新建 exe / Windows Service
|
||||
- 不改变 Public IPC / Coordinator IPC 协议
|
||||
- 不把插件市场安装迁回 Launcher
|
||||
- 不为模块间通信引入新 IPC（仅保留现有 Host↔Launcher 契约）
|
||||
|
||||
---
|
||||
|
||||
## 7. 风险与缓解
|
||||
|
||||
|
||||
| 风险 | 缓解 |
|
||||
| --------------- | ------------------------------------------------------------------ |
|
||||
| 大规模移动 merge 冲突 | B1 独立 commit，零逻辑变更 |
|
||||
| Pipeline 迁移行为回归 | 先写 Phase 级测试再迁代码；保留 `LMD_LAUNCHER_LEGACY_COORDINATOR=1` 开关一个版本（可选） |
|
||||
| AOT + DI | 显式注册，禁止反射扫描；`PublishAot` CI 步骤验证 |
|
||||
| Update 拆分遗漏路径 | CLI `update *` 与 GUI apply-update 同一 `IUpdateEngine` 门面 |
|
||||
|
||||
|
||||
---
|
||||
|
||||
## 8. Git 工作流（Agent 自主提交）
|
||||
|
||||
**原则：** 每个 Phase 验证通过后立即提交；不累积巨型 uncommitted diff。
|
||||
|
||||
**Commit 前检查（每个 commit 必做）：**
|
||||
|
||||
```bash
|
||||
dotnet build LanMountainDesktop.slnx -c Debug
|
||||
dotnet test LanMountainDesktop.slnx -c Debug --filter "FullyQualifiedName~Launcher"
|
||||
```
|
||||
|
||||
**Commit message 风格（与仓库一致）：**
|
||||
|
||||
```
|
||||
refactor(launcher): replace LauncherFlowCoordinator with LaunchPipeline
|
||||
|
||||
Pipeline + Phase pattern; LauncherOrchestrator becomes GUI entry.
|
||||
No deployment or IPC contract changes.
|
||||
```
|
||||
|
||||
**禁止：** `git push --force`、修改 git config、跳过 hooks（除非 hook 失败需修复后新 commit）。
|
||||
|
||||
**建议分支：** `refactor/launcher-internal-modularization`（单 long-lived 分支，按 Phase 连续 commit；或每 Phase 一个 PR 由用户决定 merge 时机）。
|
||||
|
||||

|
||||
|
||||
## 9. 整体完成定义（Definition of Done）
|
||||
|
||||
- 无 `LauncherFlowCoordinator` 源文件
|
||||
- `App.axaml.cs` ≤120 行，仅 Avalonia + Orchestrator 委托
|
||||
- `UpdateEngineService` 巨型文件已替换为 Facade + Strategies
|
||||
- 职责域目录就位，架构测试通过
|
||||
- 全量 Launcher 相关测试 + AOT publish smoke 通过
|
||||
- 安装包结构与 IPC 拓扑与重构前一致
|
||||
- 每个 Phase 有对应 Git commit，工作区 clean

# Launcher 单项目内部解耦改造计划（执行版）
|
||||
|
||||
## 0. 硬性约束
|
||||
|
||||
|
||||
| 约束 | 说明 |
|
||||
| ------------ | --------------------------------------------------------------------------------------------------------------------------------------------------------- |
|
||||
| **单项目** | 仅 `[LanMountainDesktop.Launcher/LanMountainDesktop.Launcher.csproj](LanMountainDesktop.Launcher/LanMountainDesktop.Launcher.csproj)`，不新建 Launcher.* 独立程序集 |
|
||||
| **单 exe** | 仍只发布 `LanMountainDesktop.Launcher.exe`（AOT 单文件） |
|
||||
| **零部署风险** | 不改变安装包目录结构、不引入新进程、不改变 Public IPC / Coordinator IPC 拓扑与契约 |
|
||||
| **增量重构** | 一个职责域一域推进，每步 `dotnet build` + 相关 `dotnet test` 通过后再进下一步 |
|
||||
| **单进程性能** | 模块间仅 in-process 接口调用，不为解耦新增 IPC |
|
||||
| **未来可拆** | 各域暴露 `I`* 接口，将来若需多进程可直接复用契约 |
|
||||
| **Git 自主提交** | Agent 在每个职责域完成且验证通过后 **自动 commit**，无需用户手动提交（见 §8） |
|
||||
|
||||
|
||||
外部共享库 `[LanMountainDesktop.PluginPackaging](LanMountainDesktop.PluginPackaging/)` 保留（Host + Launcher CLI 共用），不属于 Launcher 拆分。
|
||||
|
||||
---
|
||||
|
||||
## 1. 验收标准（必须全部满足）
|
||||
|
||||
### 1.1 零部署风险
|
||||
|
||||
- Inno Setup / CI 产物仍只有：`LanMountainDesktop.Launcher.exe` + `app-{version}/` + `.launcher/`
|
||||
- Host 调用 Launcher 的 CLI 参数、`launch-source`、`apply-update` 路径不变
|
||||
- Public IPC routes（`lanmountain.launcher.startup-progress`、`loading-state`）与 Coordinator pipe 不变
|
||||
- VeloPack / 更新 apply 状态机（`.current/.partial/.destroy`）行为不变
|
||||
|
||||
### 1.2 增量可验证
|
||||
|
||||
- 每个 Phase 结束：编译绿 + 该域新增/既有测试绿
|
||||
- 允许「纯移动文件」的 PR 单独提交，行为 diff 为零
|
||||
|
||||
### 1.3 测试友好
|
||||
|
||||
- `Startup/`、`Update/`、`Deployment/` 内类型 **无 Avalonia 依赖**，可独立单元测试
|
||||
- 每个 `ILaunchPhase`、每个 Update 策略类各有对应测试类
|
||||
- 保留并扩展现有 `[LauncherStartupTimeoutPolicyTests](LanMountainDesktop.Tests/LauncherStartupTimeoutPolicyTests.cs)`、`[LauncherMultiInstancePolicyTests](LanMountainDesktop.Tests/LauncherMultiInstancePolicyTests.cs)`
|
||||
|
||||
### 1.4 启动性能
|
||||
|
||||
- Pipeline 阶段为同步/异步方法调用链，不引入额外进程或网络
|
||||
- DI 容器仅在进程入口构建一次；Stage/Phase 实例可复用 Singleton
|
||||
|
||||
### 1.5 代码结构目标
|
||||
|
||||
|
||||
| 对象 | 当前（实测） | 目标 |
|
||||
| ----------------------------------- | -------------------------------------------- | --------------------------------------------------- |
|
||||
| `LauncherFlowCoordinator` 全 partial | ~1880 行（859+568+279+…） | **删除**；逻辑迁入 Pipeline + Phases |
|
||||
| `RunAsync()` 等价逻辑 | 跨 partial ~800+ 行 while/阶段混杂 | **≤80 行** 编排入口，细节在各 Phase |
|
||||
| `UpdateEngineFacade` | ~1849 行 | 门面 **≤200 行** + Update 内部策略/基础设施类各 **≤300 行** |
|
||||
| `App.axaml.cs` | ~258 行（已部分瘦身） | **≤120 行**：纯 Avalonia + 一行委托 `LauncherOrchestrator` |
|
||||
| `LauncherOrchestrator` | 不存在（逻辑在 Coordinator + CompositionRoot 546 行） | **≤250 行**：GUI 入口编排 |
|
||||
| `LauncherCompositionRoot` | ~546 行 | **≤150 行**：仅 DI 构建 + 入口分发 |

||||

**命名约定：**
|
||||
|
||||
- `**LauncherOrchestrator`**：GUI 生命周期内的唯一编排入口（取代 `LauncherFlowCoordinator` 对外角色）
|
||||
- `**LaunchPipeline`**：按序执行 `ILaunchPhase` 列表
|
||||
- `**ILaunchPhase**`：原 `ILaunchPipelineStage`；每个 Phase 对应原 `RunAsync` 中一个职责段

|
||||
|
||||
- `Deployment/`、`Update/`、`Startup/`：**禁止** `using Avalonia`
|
||||
- `Views/`：**禁止** 引用具体 `UpdateEngineFacade` / `DeploymentLocator`（仅接口或 Orchestrator）

|
||||
|
||||
## 3. 三大核心拆分（用户指定）
|
||||
|
||||
### 3.1 拆分 `LauncherFlowCoordinator`：`RunAsync` → Pipeline + Phase
|
||||
|
||||
**现状：** 逻辑分散在 4 个 partial，等效一个 1800+ 行 God Class；`RunAsync` 内含清理、OOBE、更新、启动、IPC 监听、超时 while-loop、多实例分支。
|
||||
|
||||
**目标 API（单项目 `Shell/` 内）：**
|
||||
|
||||
```csharp
|
||||
internal interface ILaunchPhase
|
||||
{
|
||||
string PhaseId { get; }
|
||||
/// <returns>null = 继续下一阶段；非 null = 管道终止并返回结果</returns>
|
||||
Task<LauncherResult?> ExecuteAsync(LaunchContext context, CancellationToken cancellationToken);
|
||||
}
|
||||
|
||||
internal sealed class LaunchPipeline
|
||||
{
|
||||
public LaunchPipeline(IEnumerable<ILaunchPhase> phases) { ... }
|
||||
public Task<LauncherResult> RunAsync(LaunchContext context, CancellationToken ct);
|
||||
}
|
||||
```
|
||||
|
||||
**Phase 映射（与原 RunAsync 步骤一一对应）：**
|
||||
|
||||
|
||||
| Phase | 原 RunAsync 段 | 产出 |
|
||||
| ------------------------- | --------------------------------------- | ----------------------------- |
|
||||
| `CleanupDeploymentsPhase` | `CleanupOldDeployments` | 无 UI |
|
||||
| `ExistingHostProbePhase` | 多实例 / Public IPC 探测 | 可短路成功 |
|
||||
| `ApplyPendingUpdatePhase` | `_updateEngine.ApplyPendingUpdateAsync` | 失败仍继续 |
|
||||
| `OobeGatePhase` | migration + OOBE steps | UI via `ILauncherUiPresenter` |
|
||||
| `LaunchHostPhase` | `LaunchHostWithIpcAsync` | Process + plan |
|
||||
| `MonitorStartupPhase` | while-loop + IPC + timeout | 调用 `IHostStartupMonitor` |
|
||||
|
||||
|
||||
`**LauncherOrchestrator` 职责：**
|
||||
|
||||
- 接收 `SplashWindow`、构建 `LaunchContext`（含 reporter、attempt registry、coordinator server）
|
||||
- 调用 `LaunchPipeline.RunAsync`
|
||||
- 管理 Splash/Error 窗口生命周期（委托 `ILauncherUiPresenter`）
|
||||
- **不含** 更新/部署/IPC 细节
|
||||
|
||||
**删除清单：** `LauncherFlowCoordinator.cs` 及全部 partial 文件。
|
||||
|
||||
---
|
||||
|
||||
### 3.2 拆分 `UpdateEngineFacade` → 门面 + 策略类
|
||||
|
||||
**现状：** 原 `UpdateEngineFacade` 为 1800+ 行单文件，混合检测、验签、解压、激活、快照、回滚、清理。
|
||||
|
||||
**目标结构：**
|
||||
|
||||
```
|
||||
Update/
|
||||
├── IUpdateEngine.cs # 对外契约（未来多进程可原样抽出）
|
||||
├── UpdateEngineFacade.cs # 门面，编排策略，≤200 行
|
||||
├── PendingUpdateDetector.cs # CheckPendingUpdate
|
||||
├── UpdateSignatureVerifier.cs # manifest + RSA 签名 / hash
|
||||
├── LegacyUpdateApplier.cs # Legacy zip apply
|
||||
├── PlondsUpdateApplier.cs # PLONDS manifest apply
|
||||
├── DeploymentActivator.cs # .current / .partial / .destroy
|
||||
├── UpdateSnapshotStore.cs # snapshots 读写
|
||||
├── InstallCheckpointStore.cs # resume checkpoint
|
||||
├── RollbackStrategy.cs # rollback CLI/GUI
|
||||
└── IncomingArtifactsCleaner.cs # CleanupIncomingArtifacts
|
||||
```
|
||||
|
||||
**门面方法映射：**
|
||||
|
||||
|
||||
| `IUpdateEngine` 公开方法 | 委托策略 |
|
||||
| ---------------------------- | ------------------------------------------------------ |
|
||||
| `CheckPendingUpdate()` | `PendingUpdateDetector` |
|
||||
| `ApplyPendingUpdateAsync()` | Detector → Verifier → Legacy/PLONDS Applier → Activator → Snapshot/Checkpoint |
|
||||
| `RollbackLatest()` | `RollbackStrategy` |
|
||||
| `CleanupIncomingArtifacts()` | `IncomingArtifactsCleaner` |
|
||||
| `DownloadAsync()`（若有） | 保持或拆 `UpdateDownloader` |
|
||||
|
||||
|
||||
**测试：** 每个 Strategy 独立 mock `IDeploymentLocator` / 文件系统，不启 Avalonia。
|
||||
|
||||
---
|
||||
|
||||
### 3.3 精简 `App.axaml.cs` → 纯 Avalonia + `LauncherOrchestrator`
|
||||
|
||||
**现状：** ~258 行，仍含 apply-update、air-app-broker、preview、coordinator attach 等分支。
|
||||
|
||||
**目标结构：**
|
||||
|
||||
```csharp
|
||||
// App.axaml.cs 目标形态（概念）
|
||||
public override void OnFrameworkInitializationCompleted()
|
||||
{
|
||||
if (ApplicationLifetime is IClassicDesktopStyleApplicationLifetime desktop)
|
||||
{
|
||||
var context = LauncherRuntimeContext.Current;
|
||||
var mode = LauncherEntryModeResolver.Resolve(context);
|
||||
_ = LauncherOrchestrator.RunAsync(desktop, context, mode);
|
||||
}
|
||||
base.OnFrameworkInitializationCompleted();
|
||||
}
|
||||
```
|
||||
|
||||
**从 App 迁出的逻辑 → `Shell/EntryHandlers/`：**
|
||||
|
||||
|
||||
| 现 App 分支 | 新 Handler |
|
||||
| ----------------- | -------------------------------------- |
|
||||
| `launch` + splash | `GuiLaunchEntryHandler` → Orchestrator |
|
||||
| `apply-update` | `ApplyUpdateEntryHandler` |
|
||||
| `air-app-broker` | `AirAppBrokerEntryHandler` |
|
||||
| debug preview | `PreviewEntryHandler` |
|
||||
|
||||
|
||||
**验收：** `App.axaml.cs` ≤120 行；不含 `new UpdateEngineFacade` / `new DeploymentLocator` / while-loop。

```
|
||||
|
||||
|
||||
|
||||
### Phase A：Startup 子系统 + AOT 生产 bug（优先）
|
||||
|
||||
- 抽出 `Startup/HostStartupMonitor.cs`（从 partial 独立）
|
||||
- 修复 IPC 连接退避、成功判定统一走 `StartupSuccessTracker`
|
||||
- Host 侧 `DesktopVisible` 上报对齐（仅日志/时序，不改 IPC 契约）
|
||||
- 测试 + `**git commit**`: `fix(launcher): extract HostStartupMonitor and harden startup detection`
|
||||
|
||||
### Phase B1：目录迁移（零逻辑变更）
|
||||
|
||||
- 物理移动文件到 `Deployment/`、`Update/`、`Startup/` 等，更新 namespace
|
||||
- `dotnet build` + test
|
||||
- `**git commit**`: `refactor(launcher): reorganize into responsibility folders`
|
||||
|
||||
### Phase B2：Pipeline + Phase + LauncherOrchestrator
|
||||
|
||||
- 实现 `ILaunchPhase`、`LaunchPipeline`、`LauncherOrchestrator`
|
||||
- 逐 Phase 从 Coordinator 迁移逻辑（可先并行运行对照测试）
|
||||
- 删除 `LauncherFlowCoordinator*`
|
||||
- `**git commit**`: `refactor(launcher): replace LauncherFlowCoordinator with LaunchPipeline`
|
||||
|
||||
### Phase B3：App.axaml.cs 精简
|
||||
|
||||
- EntryHandlers 提取；App 仅 Avalonia + Orchestrator 委托
|
||||
- `**git commit**`: `refactor(launcher): slim App.axaml.cs to Avalonia shell only`
|
||||
|
||||
### Phase C：轻量 DI
|
||||
|
||||
- `LauncherServiceRegistration.cs` + `Microsoft.Extensions.DependencyInjection`
|
||||
- Program / CliHost / CompositionRoot 统一 `ServiceProvider`
|
||||
- `**git commit**`: `refactor(launcher): add composition-root DI wiring`
|
||||
|
||||
### Phase D：UpdateEngine 策略拆分（可与 B2 并行，依赖 B1）
|
||||
|
||||
- 已完成：`UpdateEngineFacade` 收敛为 119 行 `IUpdateEngine` 门面
|
||||
- 已完成：提取 pending 检测、签名、Legacy/PLONDS apply、激活、快照、checkpoint、回滚、incoming 清理等 Update 内部类
|
||||
- 已完成：补 `UpdateStrategyTests` 覆盖关键策略行为
|
||||
- `**git commit**`: `refactor(launcher): split UpdateEngine into strategy classes`
|
||||
|
||||
### Phase E：守卫 + 文档 + AOT 回归
|
||||
|
||||
- 已完成：`LauncherArchitectureTests` 守住无 Avalonia 依赖、`IUpdateEngine` 依赖边界、门面/CompositionRoot 行数阈值
|
||||
- 已完成：更新 `docs/LAUNCHER.md`、`docs/ARCHITECTURE.md`、`docs/DEVELOPMENT.md`、`docs/UPDATE_SYSTEM.md`
|
||||
- 已验证：Debug build、Launcher/Update/Architecture 过滤测试、全量测试；AOT publish 本地 smoke 通过（保留现有 AOT/trim warnings）
|
||||
- `**git commit**`: `docs(launcher): document module boundaries and add architecture tests`
|

## 5. Phase / Service 测试矩阵
|
||||
|
||||
|
||||
| 组件 | 测试文件 | 覆盖点 |
|
||||
| ----------------------- | ---------------------------- | --------------------------------- |
|
||||
| `StartupSuccessTracker` | `StartupSuccessTrackerTests` | Foreground/Tray/Background policy |
|
||||
| `HostStartupMonitor` | `HostStartupMonitorTests` | 超时、IPC 延迟、ShellStatus 轮询 |
|
||||
| `LaunchPipeline` | `LaunchPipelineTests` | Phase 短路、失败传播 |
|
||||
| 各 `ILaunchPhase` | `*PhaseTests` | 单阶段 mock |
|
||||
| `PendingUpdateDetector` | `PendingUpdateDetectorTests` | 无 pending / corrupt |
|
||||
| `DeploymentActivator` | `DeploymentActivatorTests` | 标记文件状态机 |
|
||||
| `RollbackStrategy` | `RollbackStrategyTests` | 快照回退 |
|
||||
| 命名空间规则 | `LauncherArchitectureTests` | 无 Avalonia 泄漏 |
|
||||
|
||||
|
||||
---
|
||||
|
||||
## 6. 明确不做
|
||||
|
||||
- 不新建 csproj（Launcher.Deployment 等）
|
||||
- 不新建 exe / Windows Service
|
||||
- 不改变 Public IPC / Coordinator IPC 协议
|
||||
- 不把插件市场安装迁回 Launcher
|
||||
- 不为模块间通信引入新 IPC（仅保留现有 Host↔Launcher 契约）
|
||||
|
||||
---
|
||||
|
||||
## 7. 风险与缓解
|
||||
|
||||
|
||||
| 风险 | 缓解 |
|
||||
| --------------- | ------------------------------------------------------------------ |
|
||||
| 大规模移动 merge 冲突 | B1 独立 commit，零逻辑变更 |
|
||||
| Pipeline 迁移行为回归 | 先写 Phase 级测试再迁代码；保留 `LMD_LAUNCHER_LEGACY_COORDINATOR=1` 开关一个版本（可选） |
|
||||
| AOT + DI | 显式注册，禁止反射扫描；`PublishAot` CI 步骤验证 |
|
||||
| Update 拆分遗漏路径 | CLI `update *` 与 GUI apply-update 同一 `IUpdateEngine` 门面 |
|
||||
|
||||
|
||||
---
|
||||
|
||||
## 8. Git 工作流（Agent 自主提交）
|
||||
|
||||
**原则：** 每个 Phase 验证通过后立即提交；不累积巨型 uncommitted diff。
|
||||
|
||||
**Commit 前检查（每个 commit 必做）：**
|
||||
|
||||
```bash
|
||||
dotnet build LanMountainDesktop.slnx -c Debug
|
||||
dotnet test LanMountainDesktop.slnx -c Debug --filter "FullyQualifiedName~Launcher"
|
||||
```
|
||||
|
||||
**Commit message 风格（与仓库一致）：**
|
||||
|
||||
```
|
||||
refactor(launcher): replace LauncherFlowCoordinator with LaunchPipeline
|
||||
|
||||
Pipeline + Phase pattern; LauncherOrchestrator becomes GUI entry.
|
||||
No deployment or IPC contract changes.
|
||||
```
|
||||
|
||||
**禁止：** `git push --force`、修改 git config、跳过 hooks（除非 hook 失败需修复后新 commit）。
|
||||
|
||||
**建议分支：** `refactor/launcher-internal-modularization`（单 long-lived 分支，按 Phase 连续 commit；或每 Phase 一个 PR 由用户决定 merge 时机）。
|
||||
|
||||
---
|
||||
|
||||
## 9. 整体完成定义（Definition of Done）
|
||||
|
||||
- 无 `LauncherFlowCoordinator` 源文件
|
||||
- `App.axaml.cs` ≤120 行，仅 Avalonia + Orchestrator 委托
|
||||
- `UpdateEngineFacade` 巨型文件已替换为薄门面 + Update 内部策略/基础设施类
|
||||
- 职责域目录就位，架构测试通过
|
||||
- 全量 Launcher 相关测试 + AOT publish smoke 通过
|
||||
- 安装包结构与 IPC 拓扑与重构前一致
|
||||
- 每个 Phase 有对应 Git commit，工作区 clean

## 详细变更分析
|
||||
|
||||
### 架构变更概述
|
||||
此提交进行了重要的架构调整：将插件待处理（pending）功能从 Launcher 移到了 Host（主程序），并引入了新的 PluginPackaging 项目。
|
||||
|
||||
### 新增项目
|
||||
1. **LanMountainDesktop.PluginPackaging** - 新的插件打包项目
|
||||
- `PendingPluginUpgradeStore.cs` - 待处理插件升级存储
|
||||
- `PluginPackageInstallOptions.cs` - 插件包安装选项
|
||||
- `PluginPackageInstallResult.cs` - 插件包安装结果
|
||||
- `PluginPackageInstaller.cs` - 插件包安装器
|
||||
- `PluginPackageManifest.cs` - 插件包清单
|
||||
- `PluginPackageManifestReader.cs` - 插件包清单读取器
|
||||
- `PluginPackagingConstants.cs` - 插件打包常量
|
||||
|
||||
### 删除项目
|
||||
1. **LanMountainDesktop.PluginUpgradeHelper** - 已删除的插件升级辅助项目
|
||||
- `Program.cs` - 主程序（372行）
|
||||
|
||||
### 主要删除的文件
|
||||
1. `FlexibleHostLocator.cs` - 灵活主机定位器（634行）
|
||||
2. `UpdateCheckService.cs` - 更新检查服务（161行）
|
||||
3. `LauncherClient.cs` - Launcher 客户端（210行）
|
||||
4. `CliLauncherUpdateBridge.cs` - CLI Launcher 更新桥接（48行）
|
||||
5. `IpcLauncherUpdateBridge.cs` - IPC Launcher 更新桥接（171行）
|
||||
|
||||
### 主要变更的文件
|
||||
1. `PendingPluginUpgradeService.cs` - 大幅简化
|
||||
2. `PluginMarketInstallService.cs` - 大幅简化，移除了通过 Launcher 安装的逻辑
|
||||
3. `PluginRuntimeService.cs` - 新增 `ApplyPendingPluginOperations()` 方法
|
||||
4. 多个文档文件更新 - 反映架构变更
|
||||
|
||||
### 架构变化要点
|
||||
|
||||
#### 1. 职责转移
|
||||
- **之前**：Launcher 负责插件待处理安装/升级
|
||||
- **现在**：Host（主程序）负责在启动时应用待处理插件操作
|
||||
|
||||
#### 2. 新的流程
|
||||
1. 插件市场下载包到用户的待处理队列
|
||||
2. 下次 Host 启动时，在插件发现前应用待处理操作
|
||||
3. Launcher 保留 CLI 命令作为维护兼容性入口
|
||||
|
||||
#### 3. 新增功能
|
||||
- `PluginRuntimeService.ApplyPendingPluginOperations()` - 应用待处理插件操作
|
||||
- `PendingPluginUpgradeService.AddPendingInstallOrUpgrade()` - 添加待处理安装或升级
|
||||
- 新增 `RestartRequired` 状态到 `AirAppMarketInstallState`
|
||||
|
||||
## 代码审查要点
|
||||
|
||||
### 优势
|
||||
1. **架构更清晰**：Launcher 专注于版本管理和更新，Host 专注于插件运行时
|
||||
2. **减少权限需求**：插件安装不需要通过 Launcher，减少了权限提升的场景
|
||||
3. **简化代码**：删除了大量桥接代码和复杂的协调逻辑
|
||||
4. **更好的用户体验**：插件安装在 Host 启动时完成，用户体验更流畅
|
||||
|
||||
### 潜在风险
|
||||
1. **功能回归风险**：删除了大量代码，需要确保所有功能都已正确迁移
|
||||
2. **兼容性**：CLI 命令作为兼容性入口，需要确保仍然正常工作
|
||||
3. **升级路径**：现有用户的待处理插件队列需要正确迁移
|
||||
4. **错误处理**：Host 启动时的插件安装失败需要妥善处理
|
||||
|
||||
### 建议
|
||||
1. 完整测试插件市场安装/升级流程
|
||||
2. 测试 CLI 插件命令的兼容性
|
||||
3. 测试待处理插件操作在 Host 启动时的应用
|
||||
4. 验证升级路径，确保现有用户平滑过渡
|
||||
5. 检查错误处理和日志记录是否完善

### 重命名文件
|
||||
1. `LanMountainDesktop.Launcher/Update/UpdateEngineService.cs` → `LanMountainDesktop.Launcher/Update/UpdateEngineFacade.cs`
|
||||
|
||||
### 主要变更点
|
||||
|
||||
#### 1. 依赖注入重构
|
||||
- 新增 `LanMountainDesktop.Launcher/Shell/LauncherServiceRegistration.cs` - DI 服务注册
|
||||
- 修改 `LanMountainDesktop.Launcher/Shell/LauncherCompositionRoot.cs` - 组合根
|
||||
- 更新 `LanMountainDesktop.Launcher/Program.cs` - 入口点调整
|
||||
|
||||
#### 2. 更新引擎重构
|
||||
- 新增 `IUpdateEngine` 接口，定义更新引擎契约
|
||||
- `UpdateEngineService` 重命名为 `UpdateEngineFacade` 并实现接口
|
||||
- 将更新相关逻辑从巨大的协调器中解耦
|
||||
|
||||
#### 3. 协调器移除
|
||||
- 删除了 `LauncherFlowCoordinator` 及其分部类（共约 1436 行代码）
|
||||
- 功能已由 `LauncherOrchestrator` + `LaunchPipeline` 替代
|
||||
|
||||
#### 4. 架构测试
|
||||
- 新增 `LauncherArchitectureTests` 测试：
|
||||
- 验证 Deployment/Update/Startup/Infrastructure 命名空间不依赖 Avalonia
|
||||
- 确认 `LauncherFlowCoordinator` 已不存在
|
||||
|
||||
#### 5. 命名空间调整
|
||||
- 多个视图文件的 `using` 语句从 `LanMountainDesktop.Launcher.Services` 改为 `LanMountainDesktop.Launcher.Infrastructure`
|
||||
|
||||
#### 6. 文档更新
|
||||
- 更新 `docs/LAUNCHER.md`，反映新的架构设计
|
||||
- 移除对 `LauncherFlowCoordinator` 的描述
|
||||
- 添加对 `LauncherOrchestrator` / `LaunchPipeline` 的说明
|
||||
- 文档化 `IUpdateEngine` / `UpdateEngineFacade`
|
||||
|
||||
## 代码审查要点
|
||||
|
||||
### 优势
|
||||
1. **架构清晰**：通过 DI 和接口解耦，代码结构更清晰
|
||||
2. **责任分离**：将巨型协调器拆分为多个职责单一的组件
|
||||
3. **可测试性**：新增架构测试，确保关键架构约束得到执行
|
||||
4. **文档更新**：同步更新了架构文档
|
||||
5. **代码简化**：净减少 1344 行代码，去除了冗余
|
||||
|
||||
### 潜在风险
|
||||
1. **大规模删除**：删除了大量代码，需要确保没有遗漏功能
|
||||
2. **依赖注入引入**：新引入 DI 框架，需要验证服务注册是否完整
|
||||
3. **接口变更**：`UpdateEngineService` 重命名并改为接口实现，需确保所有引用都已更新
|
||||
|
||||
### 建议
|
||||
1. 运行完整的测试套件，特别是启动流程和更新相关测试
|
||||
2. 进行端到端测试，验证启动流程是否正常工作
|
||||
3. 检查插件相关功能是否仍然正常（提到了插件 pending 处理）

## 详细变更分析
|
||||
|
||||
### 变更的文件
|
||||
`LanMountainDesktop.Launcher/Startup/HostStartupMonitor.cs`
|
||||
|
||||
### 具体变更
|
||||
修改了 `HostStartupMonitor` 中的 `Request` 记录的 `ComposeLaunchDetails` 函数签名：
|
||||
- **之前**：`Func<bool, bool, bool, Dictionary<string, string>>`
|
||||
- **之后**：`Func<bool, bool, Dictionary<string, string>>`
|
||||
|
||||
移除了第三个布尔参数。
|
||||
|
||||
## 代码审查要点
|
||||

||||
1. **简化接口**：减少了不必要的参数
|
||||
2. **保持兼容性**：这是一个小的调整，不会造成大的影响
|
||||
|
||||
### 潜在风险
|
||||
1. **调用点需要同步更新**：需要确保所有调用 `HostStartupMonitor` 的地方都已同步更新
|
||||
2. **参数用途不明确**：不清楚移除的参数原本的用途
|
||||
|
||||
### 建议
|
||||

|
||||
### 主要变更点
|
||||
|
||||
#### 1. 架构重构
|
||||
- **移除巨型协调器**：将 `LauncherFlowCoordinator` 的功能拆分到多个职责单一的类中
|
||||
- **引入管道模式**：新增 `LaunchPipeline` 来管理启动流程
|
||||
- **阶段化设计**：将启动流程拆分为多个独立的阶段（Phase）
|
||||
|
||||
#### 2. 启动阶段设计
|
||||
新增以下启动阶段：
|
||||
- `CleanupDeploymentsPhase` - 清理部署
|
||||
- `ExistingHostProbePhase` - 现有主机探测
|
||||

||||
|
||||
#### 4. 入口处理
|
||||
- 新增 `LaunchEntryHandlers` 和 `PreviewEntryHandler`
|
||||
- 将入口处理逻辑从 `App` 类中移出
|
||||
|
||||
#### 5. App 类精简
|
||||
- `App.axaml.cs` 从 815 行大幅减少
|
||||
- 逻辑被分散到各个专门的类中
|
||||
|
||||
#### 6. 测试更新
|
||||
- `LauncherAirAppLifecycleServiceTests` 更新以使用新的入口处理器
|
||||
- `LauncherGlobalUsings.cs` 添加新的命名空间引用
|
||||
|
||||

# Launcher 架构拆分评估报告
|
||||
|
||||
## 1. 现状分析
|
||||
|
||||
### 1.1 Launcher 当前职责清单
|
||||
|
||||
根据代码审查，[LanMountainDesktop.Launcher](file:///d:/github/LanMountainDesktop/LanMountainDesktop.Launcher) 当前承担 **6 个主要职责域**：
|
||||
|
||||
| 职责域 | 核心文件 | 代码量 | 复杂度 |
|
||||
|--------|---------|--------|--------|
|
||||
| **OOBE 首次体验** | `OobeStateService`, `OobeWindow`, `WelcomeOobeStep`, `DataLocationOobeStep`, `PrivacyAgreementService` | ~28 KB | 中 |
|
||||
| **Splash / 启动协调** | `LauncherFlowCoordinator`, `SplashWindow`, `LoadingDetailsWindow`, `StartupAttemptRegistry` | ~120 KB | **极高** |
|
||||
| **更新引擎** | `UpdateEngineService`, `UpdateCheckService` | ~77 KB | **极高** |
|
||||
| **插件管理** | `PluginInstallerService`, `PluginUpgradeQueueService` | ~13 KB | 低 |
|
||||
| **部署/版本管理** | `DeploymentLocator`, `FlexibleHostLocator`, `DotNetRuntimeProbe`, `LegacyVersionDetector` | ~70 KB | 高 |
|
||||
| **Air APP 生命周期** | `AirApp/*`, `LauncherBackgroundService` | ~21 KB | 中 |
|
||||
|
||||
**总计：~673 KB 源代码，95 个 .cs/.axaml 文件**
|
||||
|
||||
### 1.2 关键耦合热点
|
||||
|
||||
#### 热点 1：[LauncherFlowCoordinator.cs](file:///d:/github/LanMountainDesktop/LanMountainDesktop.Launcher/Services/LauncherFlowCoordinator.cs) — **90 KB / 2034 行**
|
||||
|
||||
这是整个 Launcher 最大的单文件，负责：
|
||||
- OOBE → Splash → Update → Plugin → Host Launch 的完整编排
|
||||
- 多实例检测与协调 (IPC coordinator)
|
||||
- 主程序启动、进程监控、超时处理
|
||||
- 激活恢复 (activation recovery)
|
||||
- 所有 UI 窗口的生命周期管理
|
||||
|
||||
> [!WARNING]
|
||||
> 这个文件是当前最大的架构债务。它同时了解所有职责域，是修改任何启动行为都必须触碰的瓶颈文件。
|
||||
|
||||
#### 热点 2：[UpdateEngineService.cs](file:///d:/github/LanMountainDesktop/LanMountainDesktop.Launcher/Services/UpdateEngineService.cs) — **72 KB / 1850 行**
|
||||
|
||||
包含两套完整的更新应用流程（Legacy 和 PLONDS），内嵌：
|
||||
- 签名验证
|
||||
- 增量文件应用
|
||||
- SHA-256/SHA-512 校验
|
||||
- 回滚机制
|
||||
- 快照管理
|
||||
- 安装检查点与断点续传
|
||||
|
||||
#### 热点 3：[App.axaml.cs](file:///d:/github/LanMountainDesktop/LanMountainDesktop.Launcher/App.axaml.cs) — **34 KB / 850 行**
|
||||
|
||||
App 入口承担了过多的运行时编排逻辑，包括：
|
||||
- Coordinator IPC 服务器的创建和管理
|
||||
- Air APP IPC broker 模式
|
||||
- 主程序进程存活监控
|
||||
- 失败恢复 UI 流程
|
||||
|
||||

|
||||

|
||||
|
||||
## 2. 方案评估
|
||||
|
||||
### Option A：多项目拆分
|
||||
|
||||
将 Launcher 拆分成独立的 .NET 项目/可执行文件：
|
||||
|
||||
| 拆分后的项目 | 职责 |
|
||||
|-------------|------|
|
||||
| `LanMountainDesktop.Launcher` | 精简入口，仅做 OOBE + Splash + 编排调度 |
|
||||
| `LanMountainDesktop.UpdateService` | 更新检查、下载、应用、回滚 |
|
||||
| `LanMountainDesktop.PluginService` | 插件安装、升级队列 |
|
||||
| `LanMountainDesktop.DeploymentManager` | 版本目录管理、主机发现 |
|
||||
|
||||
#### 优点
|
||||
- 最大化隔离：每个服务可独立部署、独立更新
|
||||
- 更新引擎可以在 Launcher 自身不运行时被调用（例如计划任务）
|
||||
- 故障隔离：插件安装崩溃不影响更新流程
|
||||
|
||||
#### 缺点
|
||||
|
||||
> [!CAUTION]
|
||||
> **这些缺点在当前阶段是致命的。**
|
||||
|
||||
- **进程间通信成本巨大**：当前 `LauncherFlowCoordinator` 的 2034 行编排逻辑严重依赖同进程内的同步/异步调用和共享状态（`TaskCompletionSource`、进程对象引用、UI Dispatcher 调度）。拆成多进程意味着每个交互点都需要 IPC 管道 + 序列化 + 超时处理 + 错误恢复。
|
||||
- **启动延迟增加**：当前 Launcher 启动到 Host 启动的路径已经很长（OOBE → 更新 → 插件 → 主机发现 → Host 进程启动 → IPC 握手）。多进程会在每个阶段增加进程启动开销。
|
||||
- **安装包膨胀**：每个独立可执行文件都需要自己的运行时依赖，即使共享 Avalonia SDK。
|
||||
- **复杂的部署协调**：Launcher 自身不可被拆分更新——它就是更新的入口。如果 `UpdateService` 是独立进程，谁来启动它？又需要一个 meta-launcher。
|
||||
- **当前代码并未准备好**：`LauncherFlowCoordinator.RunAsync()` 是一个巨大的异步方法，内部有十几个局部变量和闭包在多个 await 之间共享状态。这些状态不可能简单地序列化为 IPC 消息。
|
||||
|
||||
#### 改造工程量估算
|
||||
- **IPC 层**：需新增 ~8-10 个 IPC 契约、每个有请求/响应/通知消息
|
||||
- **进程管理**：需要为每个子服务编写进程启动、健康检查、重启逻辑
|
||||
- **状态同步**：`StartupAttemptRegistry` 的锁文件机制需要扩展为跨进程锁
|
||||
- **估计 3-5 人周**，且引入大量新的故障模式
|
||||
|
||||
---
|
||||
|
||||
### Option B：单项目内部解耦（推荐）
|
||||
|
||||
保持单一 Launcher 可执行文件，通过以下手段实现内部解耦：
|
||||
|
||||
#### 阶段 1：职责分层（重构目录结构）
|
||||
|
||||
```

|
||||
#### 阶段 2：拆分 LauncherFlowCoordinator
|
||||
|
||||
将 2034 行的 `RunAsync()` 重构为 Pipeline + Phase 模式：
|
||||
|
||||
```csharp
|
||||
// 启动管道定义（伪代码）
|
||||
public class StartupPipeline
|
||||
{
|
||||
private readonly IReadOnlyList<IStartupPhase> _phases;
|
||||
|
||||
public async Task<LauncherResult> ExecuteAsync(StartupContext context)
|
||||
{
|
||||
foreach (var phase in _phases)
|
||||
{
|
||||
var result = await phase.ExecuteAsync(context);
|
||||
if (!result.Continue) return result.LauncherResult;
|
||||
}
|
||||
return LauncherResult.Success();
|
||||
}
|
||||
}
|
||||
|
||||
// 各阶段独立实现
|
||||
public class CleanupPhase : IStartupPhase { ... }
|
||||
public class OobePhase : IStartupPhase { ... }
|
||||
public class UpdatePhase : IStartupPhase { ... }
|
||||
public class PluginUpgradePhase : IStartupPhase { ... }
|
||||
public class HostLaunchPhase : IStartupPhase { ... }
|
||||
public class StartupMonitorPhase : IStartupPhase { ... }
|
||||
```
|
||||
|
||||
#### 阶段 3：拆分 UpdateEngineService
|
||||
|
||||
将 1850 行的更新引擎拆分为独立的策略类：
|
||||
|
||||
```csharp
|
||||
// 更新引擎成为协调者，不再包含实现
|
||||
public class UpdateEngineService
|
||||
{
|
||||
private readonly IUpdateApplier _legacyApplier;
|
||||
private readonly IUpdateApplier _plondsApplier;
|
||||
private readonly ISignatureVerifier _signatureVerifier;
|
||||
private readonly IUpdateSnapshotManager _snapshotManager;
|
||||
...
|
||||
}
|
||||
```
|
||||
|
||||
#### 阶段 4：精简 App.axaml.cs
|
||||
|
||||
将 850 行的 App 入口精简为纯粹的 Avalonia 应用初始化 + 委托给 `LauncherOrchestrator`：
|
||||
|
||||
```csharp
|
||||
public override void OnFrameworkInitializationCompleted()
|
||||
{
|
||||
if (ApplicationLifetime is IClassicDesktopStyleApplicationLifetime desktop)
|
||||
{
|
||||
var orchestrator = new LauncherOrchestrator(desktop, LauncherRuntimeContext.Current);
|
||||
_ = orchestrator.RunAsync();
|
||||
}
|
||||
base.OnFrameworkInitializationCompleted();
|
||||
}
|
||||
```
|
||||
|
||||
#### 优点
|
||||
- **零部署风险**：不改变安装包结构、不引入新进程、不改变 IPC 拓扑
|
||||
- **增量重构**：可以一个职责域一个域地逐步重构，每次重构都可编译验证
|
||||
- **测试友好**：拆分后的各 Phase 和 Service 可以独立单元测试
|
||||
- **保持启动性能**：单进程内的函数调用无 IPC 开销
|
||||
- **为未来多进程做准备**：如果将来真的需要拆分进程，接口已经清晰
|
||||
|
||||
#### 缺点
|
||||
- 仍然是单进程：更新引擎崩溃会影响 Launcher 进程
|
||||
- 需要自律维持架构边界（没有编译级隔离）
|
||||
|
||||
#### 改造工程量估算
|
||||
- 阶段 1（目录重组）：~0.5 人天
|
||||
- 阶段 2（FlowCoordinator 拆分）：~2-3 人天
|
||||
- 阶段 3（UpdateEngine 拆分）：~1-2 人天
|
||||
- 阶段 4（App.axaml.cs 精简）：~0.5-1 人天
|
||||
- **总计 ~4-7 人天**，且风险可控

## 3. 决策矩阵
|
||||
|
||||
| 维度 | Option A (多项目拆分) | Option B (内部解耦) |
|
||||
|------|---------------------|-------------------|
|
||||
| **改造风险** | 🔴 高：引入新 IPC、新故障模式 | 🟢 低：纯重构，行为不变 |
|
||||
| **改造工期** | 🔴 3-5 人周 | 🟢 4-7 人天 |
|
||||
| **启动性能** | 🔴 多进程启动开销 | 🟢 零额外开销 |
|
||||
| **故障隔离** | 🟢 进程级隔离 | 🟡 需靠代码纪律 |
|
||||
| **独立更新** | 🟢 各服务可独立版本 | 🔴 单一二进制 |
|
||||
| **可测试性** | 🟢 天然隔离 | 🟢 接口拆分后等效 |
|
||||
| **安装包大小** | 🔴 膨胀（多 EXE） | 🟢 不变 |
|
||||
| **部署复杂度** | 🔴 谁更新 Launcher？ | 🟢 VeloPack 现有流程 |
|
||||
| **团队人力需求** | 🔴 需长期维护多套 IPC | 🟢 维护成本低 |

## 4. 推荐方案
|
||||
|
||||
> [!IMPORTANT]
|
||||
> **推荐 Option B：单项目内部解耦**，原因如下：
|
||||
|
||||
1. **当前阶段的核心瓶颈不是项目边界，而是文件级别的职责混乱**。`LauncherFlowCoordinator` 一个文件 2034 行，`UpdateEngineService` 一个文件 1850 行，`App.axaml.cs` 一个文件 850 行——这才是真正影响可维护性的问题。
|
||||
|
||||
2. **Launcher 的核心约束决定了它必须是单一入口**。根据 [ARCHITECTURE.md](file:///d:/github/LanMountainDesktop/docs/ARCHITECTURE.md) 的定义，Launcher 是 "应用的唯一入口"，负责版本选择、原子化更新和安全启动。这个约束使得多进程拆分的价值大打折扣。
|
||||
|
||||
3. **已经存在良好的外部进程隔离**。Host 主程序 (`LanMountainDesktop.exe`)、Air APP Host (`LanMountainDesktop.AirAppHost`) 都是独立进程。Launcher 只需要作为协调者存在，它不需要自己也拆成多个进程。
|
||||
|
||||
4. **改造投入产出比**。Option A 需要 3-5 人周且引入新风险，Option B 需要 4-7 人天且零风险，效果（可维护性、可测试性）几乎等效。
|
||||
|
||||

|
||||
|
||||
## 5. Open Questions
|
||||
|
||||
1. **是否考虑将 Launcher 的 CLI 模式（`update check`、`update apply`、`plugin install`）独立成一个无 UI 的命令行工具？** 这是一个比全面拆分轻量得多的拆分点，可以让 CI/CD 和脚本调用不依赖 Avalonia 运行时。
|
||||
|
||||
2. **`UpdateEngineService` 是否打算支持 Launcher 自身的自更新？** 如果是，可能需要一个极简的 "bootstrap updater" 组件，这是唯一可能需要独立进程的场景。
|
||||
|
||||
3. **内部解耦后，是否要引入 `Microsoft.Extensions.DependencyInjection`？** 当前所有服务都是手动 `new` 的，引入 DI 容器可以自然地约束依赖方向，但也会增加 Launcher 启动路径的复杂度。
