v0.10.0

Added

• 下载详情窗 进度地图（Progress Map）：一格一个固定分片，每行 8 列，绿色自下而上填充并显示百分比
• 详情窗标题区：总进度条 + 速度 + 暂停/继续；进度地图置于第二卡片
• 引擎按写入 offset 归入固定 DownloadPart，进度事件携带 per-part 字节

Fixed

• 暂停/恢复后分片进度不再卡住；resume 使用 gob/DB 剩余任务，禁止把 downloaded 清零
• 崩溃/强退后：约 1s 刷盘 downloaded+parts；启动恢复用 DB 重建 resume
• 详情速度显示（修正采样门槛与重渲染干扰）；操作按钮点击后立即禁用直至完成
• 多选操作后保持勾选状态

v0.9.7 — Architecture Refactoring

Added

• PdmError 实现 serde::Serialize，Tauri 命令返回结构化错误（tagged union），前端可匹配 error.kind
• 前端新增 PdmError 类型（src/types.ts）
• DownloadStateFacade 新增生命周期方法 on_paused(id) / on_deleted(id)，封装 gob 持久化决策
• 引擎集成测试：mock HTTP server + 4 个端到端测试（单引擎/并发引擎/进度事件/取消）
• EventTransformer 纯函数：引擎事件 → 结构化 EventAction，6 个单元测试
• tauriClient.ts 完整化：8 个新命令（exitApp, openFile, readLogs, getExtensionsDir, openExtensionsFolder, getFileIcon, checkUpdate, testProxy）
• DialogRenderer 共享组件：消除 App.tsx 与 src-present/App.tsx 的对话框渲染重复
• useDialog() / useSelection() 自定义 hooks，AppContext 深化
• 浏览器扩展 shared/ 共享源码 + build.sh 构建脚本
• patchDownloadProgress 纯函数及 5 个 vitest 测试

Changed

• DownloadManager 移除 network 依赖，test_proxy/check_update 直接通过 AppState 调用
• 所有 Tauri 命令返回 Result<T, PdmError>（不再 .map_err(|e| e.to_string())）
• save_gob → save_resume_state，load_gob → load_resume_state（语义更清晰）
• 前端 invoke() 调用全部经 tauriClient，零裸 invoke
• parse_message() 从 WebSocket handle_connection 提取为纯函数 + 5 个测试
• sendReliable() 签名简化（移除未使用的 referrer/tabTitle 参数）

Fixed

• 19 个空 catch {} 块全部添加注释（预期失败 vs 需追踪的异常）
• 浏览器扩展删除死代码 send() 和 looksLikeDownload()
• 移除 content.js + host_permissions: ["<all_urls>"]（无需权限的空脚本）
• 移除未使用的 zustand 依赖

v0.9.1: Post-Review Architecture Fixes

What's Changed

5 Architecture Fixes from Post-v0.9.0 Review

1. Fix silent progress loss in flush_to_db

• runtime.rs: Track per-entry flush success; failed entries stay dirty and retry on next cycle
• Previously: let _ = silently discarded DB write errors, then unconditionally marked all entries as flushed
• Added integration test with real DB writes

2. Fix rate limiter blocking tokio executor

• limiter.rs: Changed wait_n to async using tokio::time::sleep
• Previously: std::thread::sleep blocked OS threads, starving the tokio executor
• Locks are dropped before sleeping to avoid blocking other workers

3. Unify start/redownload download pipeline

• download_manager.rs: Extracted shared execute_download(DownloadSpec) method
• Both start_download and redownload_download now delegate to it
• Bug fix: redownload now uses probe_service::probe_with_fallback (was bypassing it)

4. Unify DownloadStatus serialization tests

• types.rs: Added JSON roundtrip test for all DownloadStatus variants
• db.rs: Added DB roundtrip test for all variants + parse_status edge case tests

5. Verify error event logging

• Errors already flow through handle_event → Logger → Log Dialog
• Confirmed the logging architecture is sound

v0.9.0: Architecture Deepening (6 Candidates)

What's Changed

Architecture Deepening — 6 Candidates Implemented

Candidate 2 — Collapse Download Type Trinity

• Replace DownloadConfig with EngineConfig in types/engine_config.rs
• Add DownloadItem::to_engine_config() and DownloadState::to_engine_config()
• Rename proxy_name → proxy_url in EngineConfig (fixes semantic inconsistency)
• Remove duplicate output_path field (was always identical to save_path)

Candidate 3 — Seal Engine Resume-State Seam

• Rename OnCancelled → OnResumeState (reflects actual purpose)
• WorkerPool::add_with_id accepts on_resume callback parameter
• DownloadManager creates facade-based callback via make_resume_callback()
• Engine no longer directly calls gob::save_state (seam is sealed)

Candidate 5 — Extract Platform Utilities from cmd.rs

• update.rs: AssetInfo, UpdateInfo, GithubRelease, GithubAsset, compare_versions, current_platform_suffix, check_update command
• platform.rs: sync_autostart, deploy_extensions, copy_dir_recursive, resolve_extensions_dir
• cmd.rs shrinks from 434 to ~180 lines (pure Tauri command routing)

Candidate 4 — Unify Event Vocabulary

• event_bus.rs: FrontendEvent enum (single source of truth for event names)
• EventBus struct wraps AppHandle::emit
• Remove EmittedEvent struct and direct app_handle.emit calls from cmd.rs
• constants/events.ts: EVENTS object mirrors FrontendEvent variants

Candidate 6 — Frontend Context Provider

• contexts/AppContext.tsx: AppProvider owns dialog, selectedIds, filter
• tauriClient.ts: plain object export replacing tauriCommands() function
• App.tsx: uses useAppContext() instead of useState for state
• Layout.tsx: reads from context, 19→11 props (state props removed)

Candidate 1 — Deepen DownloadManager Orchestrator

• services/chunk_planner.rs: compute_connection_count, plan_chunks, check_disk_space
• services/probe_service.rs: probe_with_fallback, build_user_agents
• download_manager.rs: inline logic replaced with service calls

Files Changed

• Created: types/engine_config.rs, event_bus.rs, update.rs, platform.rs, services/mod.rs, services/chunk_planner.rs, services/probe_service.rs, contexts/AppContext.tsx, tauriClient.ts, constants/events.ts
• Deleted: hooks/useTauriCommands.ts
• Modified: 16 existing files across backend and frontend

Full Changelog: v0.8.1...v0.9.0

v0.8.1: PdmError Structured Error Enum

What's Changed

PdmError Structured Error Enum

Replaced Result<T, String> with PdmResult<T> across the entire Rust backend, introducing a typed PdmError enum with 10 variants:

• Cancelled — download cancelled by user
• Http(u16) — HTTP status code error
• ClientBuild(String) — HTTP client construction failure
• Probe(String) — URL probe failed
• NotFound(u64) — download not found
• Db(String) — database error
• Config(String) — configuration error
• Io(String) — I/O error
• Network(String) — network error
• Other(String) — generic fallback

Automatic conversion via From impls for reqwest::Error, rusqlite::Error, io::Error, String, &str, PoisonError, and serde_json::Error. The Tauri command layer (cmd.rs) retains String for IPC compatibility.

Files Changed

• types.rs — PdmError enum, Display, Error trait, From impls, PdmResult alias
• db.rs — all methods return PdmResult
• download_manager.rs — all methods return PdmResult
• engine/mod.rs — DownloadEngine trait returns PdmResult
• engine/concurrent.rs — download() returns PdmResult, typed errors
• engine/single.rs — uses PdmError::Cancelled/Http/Io/Network
• worker.rs — add_with_id returns PdmResult
• probe.rs — returns PdmResult
• config.rs — save() returns PdmResult
• cmd.rs — DM calls use .map_err for Tauri IPC boundary
