APFSearch 0.1.1 Preview

本次更新减少索引快照的重复分配、查询中的重复计算和输入到结果之间的固定等待。

• 索引记录使用分块写时复制，保留稳定槽位和旧快照；稀疏更新通过排序键定位旧条目，批量复制未变区间。
• 规范化名称、路径和父目录采用共享文本存储；扩展名和卷标识在快照中复用。SQLite 恢复直接构造最终记录，降低中间分配。
• 查询复用求值上下文，优先采用较稀疏的三字符候选，合并重复名称条件；连续槽位批量构造位图。
• 新写入的派生缓存集中存放搜索名称，改善查询访问局部性。缓存格式仍为 1；已有缓存不会因升级被强制重写。
• 使用受限、可复用的 Rayon CPU 池处理适合并行的工作；负载较小或工作池忙碌时直接串行执行。文件扫描并发和持久化策略不因此增加。
• 输入通知改为事件循环内合并，移除固定 16 ms 等待；保留取消、过期回复检查和原生输入法组字行为。结果表增长时不再重复创建新行。
• 离线索引恢复移出 XPC 请求处理线程；索引服务采用 Adaptive 调度。查询偏好读取复用内存状态，无变化的偏好不写入数据库。
• Rust 采用 Edition 2024，补全依赖许可说明。公开版本为 0.1.1，内部构建号及数据格式保持 1。

测量范围： 在隔离的百万条合成索引、已签名 XPC 服务和真实 AppKit 控制器中，三组交替测试的常见热查询首屏 P95 从约 23–25 ms 降到 6–9 ms（每类每轮 30 次测量）。不同测试阶段的内存和算法结果详见 技术记录，不能相加作为整体加速倍数。查询测试的服务磁盘读写计数未增加；这不是所有使用场景零写入或 SSD 寿命保证。

边界： 仍为预览版。测量不包含物理键盘、输入法延迟或合成器最终显示；未完成真实 Intel Mac、最低系统版本、全盘工作负载、耗电和完整 Everything 行为验收。没有自动迁移或删除旧开发数据。未显示稳定端到端收益的自适应分页实验仅保留在测试代码中。

This update reduces repeated snapshot allocation, query work and fixed input latency.

• Store stable entry slots in copy-on-write blocks; locate sparse sort-order removals by key and copy unchanged runs in bulk.
• Share normalized text storage and snapshot-owned metadata labels; stream SQLite recovery into final record allocations.
• Reuse query evaluation state, prioritize sparse trigram candidates, deduplicate repeated name conditions and build contiguous bitmap runs in batches.
• Place search names together when writing prepared caches, without changing format 1 or forcing existing caches to be rewritten.
• Reuse a bounded Rayon CPU pool with serial fallback; retain bounded filesystem I/O and existing durability settings.
• Coalesce input within the event loop instead of waiting 16 ms, retaining cancellation, stale-reply isolation and native marked-text handling. Avoid recreating newly bound result rows.
• Move offline-index opening off the XPC request handler, use Adaptive service scheduling and avoid unchanged preference writes.
• Adopt Rust Edition 2024 and update dependency notices. Public version is 0.1.1; internal build and data formats remain 1.

In three alternating signed million-record fixture comparisons, common warm-query input-to-AppKit-display-submission P95 changed from approximately 23–25 ms to 6–9 ms, with 30 measured samples per query class per run. Pages, totals and row counts matched, and service query-interval disk counters did not increase. See the engineering notes for separately scoped memory and algorithm measurements; these gains must not be multiplied or treated as whole-machine results.

This remains a preview. Physical keyboard/IME latency, compositor presentation, real Intel hardware, the minimum supported OS, full-volume workloads, energy use and complete Everything parity remain unverified. Old development data is neither migrated nor deleted. Adaptive paging without a consistent end-to-end improvement remains test-only.
