yvgude/lean-ctx v3.9.16

on GitHub

Added

• Cross-agent cache benchmark — new bench_cross_agent_cache example for
  measuring OCLA delivery registry performance across concurrent agents.
• npm postinstall: multi-method download fallback — Windows installs now
  try PowerShell Invoke-WebRequest, curl.exe, and node-fetch sequentially,
  fixing installs behind corporate proxies and restrictive PATH configs.
• npm postinstall: progress + timeouts — download progress is shown inline
  with configurable timeouts (60s connect, 300s total), preventing silent hangs.
• npm postinstall: re-onboard on reinstall — npx lean-ctx-bin now runs
  onboard and shows the quick-start guide on reinstall, not just first install.

Fixed

• CRITICAL: “Cannot start a runtime from within a runtime” panic — tool
  handlers run inside spawn_blocking since #1018, where
  Handle::current().block_on() panics. All occurrences replaced with safe
  alternatives:
  • ctx_read, ctx_delta, ctx_fill, ctx_knowledge, ctx_smart_read:
    bounded_lock::{read,write}() spin-loops
  • ctx_patch, ctx_edit: spin_read!/spin_write! macros
  • ctx_tools: isolated current_thread runtime
  • multi_path: try_read_owned spin-loop
    This fixes the “lean-ctx internal error” affecting .rs/.c file reads when
    cache misses triggered the post-processing write-lock path.
• OCLA delivery registry: mtime no longer a cache discriminator — blake3
  content hash is the sole identity for cross-agent cache hits. Previously,
  git checkout/rebase changed mtime causing false cache misses despite
  identical content.
• Flaky CI: index build SIGTERM — integration tests now skip gracefully on
  both SIGKILL (OOM) and SIGTERM (CI timeout) instead of panicking.
• npm security — resolved Dependabot alerts for npm package dependencies.

Upgrade

lean-ctx update                 # recommended (auto-downloads + refreshes shell hooks)
cargo install lean-ctx          # or
npm update -g lean-ctx-bin      # or
brew upgrade lean-ctx

Note: After upgrading via cargo/npm/brew, run lean-ctx setup to refresh shell aliases. lean-ctx update does this automatically.
