Pi Agent Desktop v0.7.10 😎

🇨🇳 中文说明

我们很高兴发布 v0.7.10 版本！本次更新专注于系统架构稳定性、渲染效率以及异步 I/O 吞吐性能的深度优化。我们解决了一系列潜在的连接风暴、内存泄漏和主线程同步阻塞问题，以带来更稳定、低延迟的高频流式对话体验。

🚀 核心改进与优化

  1. SSE 连接指数退避重连与自愈故障恢复 (优化点 5)
    • 改进：SSE 连接断开时的自动重试机制从固定 1 秒探针升级为指数退避重连算法（1s -> 2s -> 4s -> 8s -> 16s，最大 30s 延迟），并将连续失败尝试次数上限限制为 5 次。
    • 自愈：当自动重连耗尽进入失败状态时，聊天视口顶部将渲染红色网络异常通知条，支持用户一键“手动重新连接”并重置重试计数。
  2. 多 onDestroy 清理回调队列 (优化点 6)
    • 改进：重构了 AgentSessionWrapper 中的清理注销逻辑，支持同时安全注册多个注销钩子。销毁会话时采用 try-catch 循环保护执行所有回调。
    • 收益：避免了多个内部模块间清理动作互相覆盖的隐患，彻底消除 Electron 与 Server 的 IPC 句柄内存泄露。
  3. 去定时器化与消息组件 Memo 隔离 (优化点 7 & 8)
    • 改进：将 UserMessageView 与 AssistantMessageView 通过 React.memo 包裹以避免重复重绘；彻底移除了流式接收时每 300ms 心跳触发的 setInterval 轮询定时器，改用 useEffect 配合纯数据驱动推演 TPS 吞吐率和 thinking 运行时长。
    • 收益：消除了高频流式输出下的计时器和状态竞争（Timer-State Competition），极大降低了 CPU 占用，打字流更加平稳流畅。
  4. 全异步会话 I/O 文件加载 (优化点 9)
    • 改进：全面使用 fs/promises 重写读盘机制，实现异步 JSONL 解析与首行会话头读取，替换掉原先在 API 接口中同步阻塞的 SessionManager.open() 方法。
    • 收益：防止在加载、切换较大会话历史文件时死锁 Node.js 服务端的事件循环，消除了页面出现无响应或卡顿的现象。
  5. 消息列表原生 CSS 虚拟化 (优化点 10)
    • 改进：在消息列表容器中引入了现代浏览器原生的 CSS 虚拟化特性：content-visibility: auto 与 contain-intrinsic-size: auto 150px。
    • 收益：由 Chromium 容器自动跳过视口外消息 DOM 的排版重绘计算。既保持了极简的 DOM 结构，又完美兼容现有的 React Ref 滚动锚定，保障超长历史对话下的 60fps 流畅滑动。
  6. 规范硬化与 100% 测试通过
    • 移除了测试代码中所有遗留的 explicit any，清理了所有未使用的变量及导入。
    • 类型校验 (npx tsc --noEmit)、ESLint 代码规范审计 (npm run lint) 和全量单元测试（135 个用例 100% 通过）均无错通过。

🇬🇧 English Release Notes

We are excited to release v0.7.10! This release focuses on deep optimizations in system architectural stability, rendering efficiency, and asynchronous I/O performance. We resolved potential connection storms, memory leaks, and event-loop blocking issues to deliver a smoother, low-latency, high-frequency streaming conversation experience.

🚀 Key Improvements & Optimizations

  1. Exponential Backoff Reconnection & Self-Healing (Opt 5)
    • Change: Replaced the fixed 1-second reconnect probe for Server-Sent Events (SSE) with an Exponential Backoff Reconnection Algorithm (1s -> 2s -> 4s -> 8s -> 16s, capped at 30s) and capped consecutive failures at 5 attempts.
    • Self-Healing: When attempts are exhausted, a red network error banner appears at the top of the chat, allowing users to trigger a manual reconnect instantly and reset the retry count.
  2. Multiple onDestroy Cleanup Callbacks (Opt 6)
    • Change: Upgraded the cleanup mechanism in AgentSessionWrapper to support a registry of multiple callback hooks, executed safely within a try-catch loop upon session destruction.
    • Impact: Eliminates cleanup overrides between internal modules, completely resolving memory and IPC handle leakage between Electron and the server.
  3. No-Timer TPS Calculation & Memoized Message Views (Opt 7 & 8)
    • Change: Wrapped sub-message views (UserMessageView, AssistantMessageView) with React.memo to isolate rendering. Removed the 300ms setInterval heartbeat loop, using a pure data-driven useEffect to calculate TPS and thinking duration on block updates.
    • Impact: Resolves timer-state competition during token streaming, drastically lowering CPU usage and resulting in a much smoother typewriter effect.
  4. Fully Asynchronous Session I/O Loading (Opt 9)
    • Change: Rewrote JSONL file loading and header extraction with asynchronous I/O using fs/promises. Removed all blocking synchronous SessionManager.open() invocations within the API layer.
    • Impact: Prevents Node.js event-loop starvation when loading or switching large session files, eliminating freeze and stutter issues.
  5. Native CSS Virtualization for Message Lists (Opt 10)
    • Change: Integrated native browser virtualization using content-visibility: auto and contain-intrinsic-size: auto 150px on message wrapper elements.
    • Impact: Offloads off-screen DOM layout and repaint operations directly to Chromium. This keeps the DOM tree lightweight while preserving existing React Refs and scroll anchoring, ensuring a fluid 60fps scrolling experience for long conversations.
  6. Strict Code Audits & 100% Unit Test Pass
    • Removed all explicit any casts from test mocks and cleaned up all unused imports and variables.
    • Successfully validated TypeScript types (npx tsc --noEmit), passed ESLint audits (npm run lint), and passed 135/135 unit tests successfully.
