codebase-memory-mcp v0.9.0
A large robustness and platform-support release since v0.8.1 — first-class Windows support, big indexing performance and memory-safety gains, broad extraction-accuracy fixes across many languages, and a substantially better graph UI.
Highlights
- First-class Windows support — end-to-end non-ASCII path handling, installer/runtime reliability fixes, a UI-hang fix, and a native windows-arm64 build + smoke pipeline.
- Indexing performance & resilience — a kernel-scale campaign cut indexing wall-time ~61% with deterministic output, plus a crash/hang supervisor that quarantines a bad file and indexes the rest instead of aborting the whole run.
- Memory safety on large repositories — accurate Linux RSS accounting, peak-vs-live reconciliation, bounded parallel retention for low-RAM machines, and a use-after-free fix in cross-thread slab frees.
- Graph UI — a configurable node budget up to 10M nodes with scaled rendering and contrast controls, dead-code filtering, node code preview, GitHub deep-links, URL routing, and offline label rendering (no remote font fetches).
- Extraction accuracy — many CALLS / IMPORTS / route-extraction correctness fixes across C/C++, Python, Go, PHP, Kotlin, Java, TypeScript/JavaScript, Rust, and more.
What's changed
Windows support
End-to-end non-ASCII path support (_wfopen, wide-argv + CreateProcessW, escaped/NUL-terminated worker command lines); installer reliability and Mark-of-the-Web docs; a git-spawn handle-inheritance fix that resolved a UI deadlock; drive-letter handling in the hook augmenter; large-.db size handling; a real error when Windows persistence export fails; and a full native windows-arm64 build + smoke pipeline.
Indexing, performance & memory safety
~61% faster kernel-scale indexing with deterministic output; a TypeScript-at-scale cascade fix with parallel-only crash recovery; a crash/hang supervisor that quarantines the culprit file; accurate /proc RSS on Linux; peak-vs-live RSS reconciliation; bounded, source-capped parallel retention for low-RAM peak RSS; supervised-subprocess RSS isolation for background auto-index/watcher; an O(1) aligned-page cross-thread slab-free fix (use-after-free); graph-buffer upsert-contract and mem-budget fixes; host-tiered RAM budget; and per-file indexing failures now reported via skipped[] + a logfile instead of failing silently.
LSP / extraction accuracy
CALLS-edge correctness (string-dispatch edges, C/C++ enclosing-function attribution, receiver-aware self-recursion, recursion-depth caps in py/go/php/kotlin, a memoized guard for a Python exponential re-eval hang); route/HTTP extraction (reject filesystem paths so client routes join server routes, canonicalize parameterized paths, Spring routes on Kotlin controllers, Django REST @action); imports/resolution (IMPORTS keyed by local name, reject non-file-like targets, tsconfig alias ../ climbs, mixed Java/Kotlin callgraph edges, stable Java USAGE ownership); plus Class.lines accuracy, INHERITS/IMPLEMENTS counted in degree, a heap-allocated walk_defs frame stack fixing stack overflow on deep files, and a reproduce-first bug suite with a 5-platform board.
Graph UI
Node budget up to 10M with scaled rendering and contrast controls; offline label rendering (no remote CDN fonts); dead-code filtering, node code preview, and GitHub deep-links; URL routing, filter-panel UX and camera fly-to; the filter sidebar stays visible when everything is filtered out; Windows folder navigation in the index picker; indexing-job failures surfaced instead of silently completing; projects unwatched on UI delete; bounded octree recursion for coincident points.
MCP server & CLI
Structured tool metadata; the CLI accepts flags, stdin, and --args-file with per-tool --help; project resolution by internal name + ghost-DB filtering and a project_name alias; trace_path no longer conflates distinct same-named functions and follows CROSS_* edges; valid UTF-8 snippets for non-UTF-8 sources; correct JSON control-char escaping; cypher label-filtered traversal no longer truncates at 10 and preserves node properties through WITH; get_architecture overview subset; detect_changes honors since.
Discovery, watcher & lifecycle
Honor .git/info/exclude, global core.excludesFile, and linked-worktree ignore sources; honor exclusions in pkgmap/path-alias/envscan walks; .cbmignore negation can no longer un-skip safety-core dirs; deploy/ dirs no longer double-indexed; scoped search handles repo paths with spaces; prune projects whose root stays missing; an auto_watch config gate; correct canonical_root for worktrees and subdirectory projects; ADR preservation across full re-index.
Grammars, build & docs
Vendored InterSystems ObjectScript grammars and the Mojo parser; SBOM now computes the grammar count and completes the non-MIT license summary. Full validation pipeline on PRs with superseded-run cancellation; issue-triage bots; per-leg smoke gating that fixes matrix collapse / false-green; gcc-15 and Nix-on-macOS build fixes. Config-file reference and extra_extensions docs.
