yvgude/lean-ctx v3.5.22

on GitHub

Fixed

• read: overlay/FUSE stat() race — read_file_lossy now opens the file first and uses fstat() on
  the file descriptor instead of a separate stat() syscall. Fixes sporadic "No such file or directory"
  errors in Docker overlay/FUSE filesystems (e.g. Codex sandboxes) where stat() can return ENOENT
  for files that exist. Adds a single retry with 50 ms backoff on NotFound before giving up.

Added

• Native Windows daemon support — IPC abstraction layer — New ipc/ module (mod.rs, process.rs, unix.rs, windows.rs) provides a platform-independent daemon transport layer. Unix uses UDS (unchanged behavior), Windows uses Named Pipes (\\.\pipe\lean-ctx-{hash}). All OS-specific code (libc::kill, PermissionsExt, UnixStream) is now isolated in ipc/unix.rs and ipc/windows.rs — no other module needs #[cfg(unix)] for daemon logic. windows-sys 0.59 added as target dependency. Implements #209.
• HTTP-based daemon shutdown — New POST /v1/shutdown endpoint enables cross-platform graceful daemon shutdown. stop_daemon() now tries HTTP shutdown first, then SIGTERM/TerminateProcess as fallback, then force kill as last resort. No more direct libc::kill(SIGTERM) in daemon.rs.
• build_app_router() extraction — Shared Axum router construction extracted from serve() and serve_uds(), eliminating ~70 lines of code duplication. Both TCP (serve()) and IPC (serve_ipc()) use the same router builder.
• Parallel call graph build with progress tracking — CallGraph::build_parallel() uses rayon for concurrent file analysis. New get_or_start_build() returns cached results immediately or starts a background build with live progress (BuildProgress struct with files_total, files_done, edges_found). Dashboard polls via /api/call-graph/status.
• Dashboard: call graph progress bar — cockpit-graph.js shows a live progress bar during call graph builds instead of a blank loading state. Auto-polls every 2s and renders the completed graph once ready.
• Dashboard: project file browser in Compression Lab — cockpit-compression.js now has two tabs: "Recent" (context ledger/events) and "Project" (all indexed files from /api/graph-files). Project tab includes search, file count, and token count per file. New /api/graph-files API endpoint returns indexed files sorted by token count.
• Dashboard: improved compression lab layout — Sidebar/main grid layout with responsive breakpoint at 900px. File list shows token counts, mode auto-switches when selecting recently read files, search input for project files.

Fixed

• 100% CPU after lean-ctx setup on Ubuntu — Two root causes fixed: (1) env.sh self-heal script could recursively spawn lean-ctx init via BASH_ENV outside containers. Now guarded with container detection (/.dockerenv), recursion guard (_LEAN_CTX_HEAL), and LEAN_CTX_ACTIVE propagation. (2) Graph index scanning could scan entire $HOME when setup was run outside a project. Now guarded with is_safe_scan_root() check, cross-process lock (startup_guard), 50k entry limit, and 2-minute timeout. LEAN_CTX_NO_INDEX env var skips indexing entirely. Fixes #210.
• daemon.rs/daemon_client.rs now platform-independent — Removed all #[cfg(unix)] gates from lib.rs, cli/dispatch.rs, and setup.rs for daemon modules. daemon_client.rs auto-start works on all platforms (previously returned None on non-Unix).
• Dashboard call graph timeout — Increased from 15s/30s to 60s to accommodate larger projects during initial build.

Changed

• serve_uds() replaced by serve_ipc() — Takes a DaemonAddr enum instead of a PathBuf. Callers use daemon::daemon_addr() instead of daemon::daemon_socket_path().
• daemon_socket_path() removed — Replaced by daemon::daemon_addr() which returns a DaemonAddr enum. All call sites updated (setup.rs, dispatch.rs).
• Security hardening test updated — uds_socket_sets_permissions now checks ipc/unix.rs instead of http_server/mod.rs (chmod 600 logic moved during IPC extraction).

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.
