Two reviewed external-fork contributions, re-implemented as clean maintainer code.
#406 / PR #407 (thanks @nvt-pankajsharma): a POSIX parent-death watchdog so the stdio MCP server exits when its launching parent dies instead of lingering on stdin. Refactors signal_handler into an idempotent request_shutdown(); a watchdog thread polls getppid() (500ms) and shuts down + exit(0) once the initial ppid (>1) changes; Windows unaffected (#ifndef _WIN32). The fork's getppid()<=1 startup early-exit was dropped (it could wrongly kill a legitimately-launched server during reparent races / in container launchers; the initial_ppid>1 guard already no-ops safely), and thread-create failure is now non-fatal (matches the watcher/HTTP background-thread policy). Adds tests/test_parent_watchdog.sh + scripts/test.sh wiring.
#413 / PR #414 (thanks @santanusinha): runtime log-level control via CBM_LOG_LEVEL (case-insensitive debug|info|warn|error|none, or numeric 0..4; unset/unknown leaves the level unchanged). getenv() before threads start (no race). Adds tests/test_log.c cases + README env-var row.
Four overload-scoring lookups (cbm_registry_lookup_method_by_types/_by_args, _symbol_by_types/_by_args) linear-scanned the entire project registry on every call site, ignoring the pre-built method_buckets/func_qn_buckets hash index that the by-name lookups already use. On a large C++ header (e.g. 10989 defs) that is O(calls x project_funcs) per file (~34s/file), so big codebases never finish indexing. Add a hashed fast path (O(overloads)) when the registry is finalized; preserve first-match semantics via lowest registration index (equivalence verified over 1606 lookups, 0 divergence); keep the linear fallback for un-finalized single-file registries so normal files are unaffected. Adds tests/test_cpp_index_hang.sh (scale-tier subprocess+timeout repro, opt-in via CBM_RUN_HANG_TEST).
- Use env: block instead of shell quoting for WIN32_LIBS in CI
- Forward WIN32_LIBS from environment in test.sh and build.sh
- Add skip_lint input to dry-run workflow for faster iteration
MinGW GCC does not ship ASan runtime on Windows. MSYS2 CLANG64
provides full sanitizer support via compiler-rt. All platforms
now run tests with ASan + UBSan — no exceptions.
- Fix GCC -O2 warnings: calloc for cf (maybe-uninitialized),
suppress stringop-truncation/alloc-size-larger-than (false positives),
guard louvain against negative node_count
- Default compiler: cc on macOS, gcc on Linux/Windows (fixes gcc-14
not found on MSYS2)
- Docker test infra now runs BOTH test (ASan) and build (-O2 -Werror)
- Add scripts/clean.sh, test.sh, build.sh, lint.sh as single source
of truth for local and CI builds (always clean, always parallel)
- Fix -Wmissing-braces: replace {{0}} with memset for struct arrays
- Fix -Wrestrict: use intermediate buffer for same-struct snprintf
- Update dry-run.yml and release.yml to use the new scripts
