- Updated gitignore loading to filter out ancestor ignore rules that match the current explicit walk root.
- Retained unrelated parent ignore rules and processed local ignore files within the root normally.
- Added a regression test to ensure ignored roots still respect nested ignore rules.
Stop pi-walker from applying .gitignore/.ignore files from unrelated ancestors above an explicit non-repository search root. Preserve repo-root ignore inheritance when scanning a subdirectory inside a repository.
Fixes#4706
- Introduced parallel streaming grep with windowed result processing to enhance search performance and memory management.
- Implemented stateful parallel file walking with buffer pooling and directory entry record caching to minimize memory allocations.
- Optimized ignore state derivation by using directory entry names instead of stat probes.
- Added comprehensive unit and performance tests covering parallel traversal correctness, early termination, and streaming behavior.
- Added `#streamTurnNonce` to prevent aborted streaming turns from corrupting content indexes of subsequent messages.
- Implemented temporary stream-key generation using content position and turn nonces for previewing tool calls without native IDs.
- Added migration logic to key pending tool previews by their real ID and rekey `ToolArgsRevealController` once the real ID is parsed.
- Removed the ignore-based fallback walker implementation and its associated dependencies.
- Simplified the directory traversal to consistently use native scanners across all platforms.
- Eliminated `WalkError::Unsupported` and `WalkStatus::Unsupported` error handling across all dependent crates.
- Added a depth-first sorting fallback for native traversal and implemented recursion detection using a symlink stack.
- Replaced standard and tokio mpsc channels with flume channels across workspace crates to simplify thread synchronization.
- Swapped standard Mutex guards for parking_lot Mutexes to avoid manual lock poisoning handling and improve performance.
- Declared workspace-wide dependencies for flume and parking_lot in root and member Cargo manifests.
- Replaced custom fast-walk and fs-cache implementations in pi-natives with a new dedicated pi-walker library.
- Integrated the thread-safe, parallel pi-walker library across pi-natives, pi-shell, pi-uu-grep, and uu-find.
- Rewrote file search, fuzzy finding, and glob-matching logic to leverage pi-walker configurations and visitor traits.
- Optimized shell process tracking in pi-shell by replacing global descendant-diff logic with an isolated, per-run SpawnRegistry.
- Added parallel rayon-based walking and optimized fast paths for directory scanning and entry classification.
