Original Pull Request: https://github.com/anomalyco/opencode/pull/8922

State: closed
Merged: No

Summary

This PR implements several high-impact optimizations to the OpenCode core to improve efficiency during AI interaction and file exploration.

Changes

  • I/O Buffering: Session.updatePart now buffers streaming deltas in memory, reducing disk writes from O(N) to O(1) per message part.
  • Compact Storage: Switched to compact JSON for internal state persistence, reducing I/O payload size.
  • Ripgrep Caching: Added a 5-second results cache for Ripgrep.tree to significantly speed up file exploration in large repositories.

Verification

  • Verified with lsp_diagnostics.
  • Ensured stability of core loops during streaming.
