v2.1.0
bb2af24

Massive indexing/search speedup, overlay startup deadlock fixes, no blank window on first show, and crate rename.

Changelog (24 commits since v2.0.0)

Performance

  • B-2: Pre-read ALL Tantivy segment files + SQLite DB into OS page cache — disk I/O eliminated from first keystroke
  • B-4: Icon decode throttle — first 8 sync, rest deferred to background thread — show latency cut ~60%
  • B-5: recv_timeout jitter + stop channel + select! instead of 50ms fixed poll — ~0.5ms idle wakeup eliminated
  • B-6: O(1) selection highlight via JS rowMap Map lookup — constant-time toggling
  • B-7: PostWebMessageAsJson sends pre-serialized JSON, JS gets object directly — IPC ~3x faster
  • B-8: Conditional scrollIntoView only when selected row outside visible area — less layout thrash
  • B-10: RwLock replaces Mutex<CoreService> — concurrent reads, no reader contention
  • Search cache warmup on overlay show — Tantivy searched once before first keystroke
  • Stale prune moved off search critical path to background thread
  • Adaptive debounce — first char instant, rapid chars coalesced at 80ms
  • Blocking evaluate_script replaced with fire-and-forget PostWebMessageAsString

Bug Fixes

  • Overlay hang after first indexing — sync_indexes_from_cache short-circuits when indexes already populated
  • ~30s delay after indexing with files — FTS5 index_items wraps inserts in BEGIN IMMEDIATE/COMMIT (was 9579 tiny segments)
  • Progress window deadlock — drop(fts5_guard) before maybe_compact_backends()
  • Progress window white flash — Delays show 200ms until WebView2 paints
  • Progress window acrylic — DWM rounded corners + acrylic blur
  • Progress evaluate_script re-enabled — Progress bar now actually updates
  • Blank window on first hotkey — Removed panel-in CSS animation (160ms opacity fade caused blank on fast press)
  • Polling thread eliminated — ControlFlow::Poll + direct AtomicU32 read replaces separate thread
  • Warm-release timer — Single timer thread replaces per-Hide thread spawning
  • Icon cache idle-trim — Dead code re-enabled, trims LRU icons when idle
  • Everything SDK race + DLL planting — Robust Everything detection

Architecture

  • Crate renamed nex-cli → nex-launch (binary stays nex.exe)
  • GUI subsystem — No console flash at startup
  • Cleanup: Remove vestigial icon_cache param from serve_asset/build_webview
  • Thread naming — All threads named for diagnostics
  • Dead SVG icon deps removed
