🚀 CodeBuddy Code v2.23.0 Release ​

Release Date: 2025-12-22

✨ New Features ​

  • Agent SDK Permission Control Support: SDK now supports tool invocation permission management, allowing clients to approve or reject tool execution requests
  • Agent SDK User Q&A Support: SDK now supports AskUserQuestion tool, enabling AI agents to ask users questions and gather feedback during execution

🚀 Performance Optimizations ​

  • Significant @ File Search Performance Boost: Optimized file search experience in large repositories, resolving lag and crash issues caused by continuous input
    • Implements single-flight full enumeration: Only one rg --files runs per @ input round, avoiding redundant scans
    • Background preloading of file lists: Uses useEffect to preload file lists during idle time, preventing first search freeze
    • Only accepting latest query results: Uses requestId mechanism to discard outdated requests, preventing result flickering and redundant calculations
    • Reduced memory allocation: Fuzzy matching directly handles string arrays, generating objects only for top results
    • Automatic cleanup on context exit: Clears scan sessions when leaving @ context, avoiding memory overhead

🐛 Bug Fixes ​

  • Fixed First Search Freeze: Uses useEffect background preloading; if preloading incomplete on first query, loads asynchronously without blocking UI response
  • Fixed Windows Path Matching Accuracy: Ensures all paths are unified to POSIX style separators before processing, avoiding split failures
  • Fixed execRg Timer Leak: Ensures timeout timers are properly cleaned up on all exit paths

Upgrade Notes ​

This release focuses on optimizing file search performance, especially when using @ symbol for file search in large codebases. If you frequently work with large projects, you'll notice significant improvements in search response speed and stability after upgrading.

Technical Details ​

File Search Architecture Optimization ​

To address large repository performance issues, this release includes a comprehensive refactoring of the file search mechanism:

  1. Single-flight Pattern: Ensures only one rg --files process runs at a time, avoiding resource contention
  2. Preloading Strategy: Preloads file lists during user idle time, improving first search response speed
  3. Request Deduplication: Automatically discards outdated search requests via requestId mechanism, ensuring result timeliness
  4. Memory Optimization: Reduces object creation and memory allocation, improving efficiency when handling large file volumes
  5. Resource Cleanup: Automatically cleans up unused search sessions, preventing memory leaks
