- Vendor TRE regex library (BSD-licensed, ~9K LOC) for Windows —
eliminates the TODO stub that caused all regex tests to fail
- Fix cbm_mkdtemp stack-buffer-overflow: use static buffer for
/tmp/ → %TEMP%\ path translation (Windows paths are longer)
- Wine test results: 1861 passed, 50 failed (Wine filesystem limits),
75 skipped — remaining failures are Wine-specific, not Windows bugs
- cbm_mkdtemp: translate /tmp/ to %TEMP%\ on Windows
- Docker test-windows: cross-compile + run under Wine (without ASan,
which doesn't work under Wine)
- Wine on PATH fix for Ubuntu noble (/usr/lib/wine/)
- Tool preflight check in Dockerfile
- 1887/1992 tests pass under Wine (52 fail: regex not available in
pure MinGW — works on real MSYS2 which provides <regex.h>)
- 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
- Replace mingw-w64 with llvm-mingw Docker image (mstorsjo/llvm-mingw)
for local cross-compilation — includes Wine for future test execution
- Fix WIN32_LIBS quoting: use single quotes so -Wl,--allow-multiple-
definition actually reaches the linker
- Install MSYS2 zlib into llvm-mingw sysroot for cross-compilation
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.
- cbm_mkdtemp: _mktemp + _mkdir on Windows
- cbm_setenv/cbm_unsetenv: _putenv_s on Windows
- cbm_pipe: _pipe on Windows
- Replace bare POSIX calls in 12 test files with compat wrappers
- All test files now include compat.h
- CBM_TLS: use _Thread_local (C11 standard) instead of __declspec(thread)
which only works on MSVC, not MinGW GCC
- Replace bare strndup() with cbm_strndup() in 6 files (strndup is POSIX,
not available on Windows)
- Guard sys/wait.h with #ifndef _WIN32 in http_server.c
- 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)
- test-windows job runs scripts/test.sh under MSYS2 (same as build)
- Remove libsqlite3-dev from all CI steps (sqlite3 is vendored now)
- Both dry-run.yml and release.yml updated
These 5 fields were detected on 3 platforms but never consumed by any
production code. The L2 cache sysfs fallback added in the previous
commit existed solely to fix a test for a value nobody reads.
Removes ~120 lines of platform-specific detection (Mach VM stats,
/proc/meminfo parsing, sysfs cache scan) and 3 dead tests.
- Arena-allocate pair_field_types in cpp_stdlib_data.c (was stack array
escaping scope via registry pointer — caught by GCC ASan)
- Add sysfs fallback for L2 cache on Linux ARM (sysconf returns 0)
- Expose cbm_node_free_fields() and fix 12+ leak sites in tests where
find_node_by_id/qn results were never freed (caught by LeakSanitizer)
GCC-only flags (-Wno-format-truncation, -Wno-unused-result) are now
conditionally added via __GNUC__ / __clang__ preprocessor detection.
Fixes Clang rejecting unknown GCC flags with -Werror on CI runners.
- 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
Enforce WarningsAsErrors: '*' with zero suppressions of entire check categories.
All non-FP warnings fixed at source; true false positives get per-instance NOLINT
with reasoning. Fixes include: braces around statements (1679), isolate declarations
(75), explicit casts for multilevel pointer conversions, missing includes, function
parameter documentation via NOLINT, and proper NOLINTBEGIN/NOLINTEND nesting.
Delete Go MCP server, CGo bridges, Go pipeline, store, tools, watcher,
cypher engine, language specs, and all Go tests. Replace Go pre-commit
hook with C-only linting (clang-tidy, cppcheck, clang-format, tests).
Tree-sitter extraction engine (internal/cbm/*.c) retained for C pipeline.
Complete C implementation of the indexing pipeline (src/), parallel worker
pool, graph buffer with merge support, SQLite writer, and 1893-test suite.
Linter setup: zero warnings from clang-tidy (all checks enabled, no NOLINT
suppressions), cppcheck, and clang-format. All issues fixed at source —
proper headers for external linkage, GROW_ARRAY macro restructured to
eliminate type parameter, null-deref paths guarded, named intermediates
for suspicious-argument checks.
Full indexing now runs entirely in RAM:
- One filepath.Walk, one bulk file read (LZ4 HC compressed sourceStore)
- In-memory SQLite for all passes, single Backup API dump at end
- Source access via C LZ4 decompression (~3μs per file, 5.7 GB/s)
Aho-Corasick engine (internal/cbm/ac.c):
- Custom ACISM automaton with bitmask output (≤64 patterns)
- Fused LZ4 decompress + AC scan in C-side thread-local buffer
- Batch API: single CGo call scans all files (ScanLZ4Batch)
- Compact alphabet mode for configlinker (38-char table)
Pipeline optimizations:
- httplinks: AC pre-screens files for HTTP client + route keywords
- configlinker: AC batch scan replaces O(n×m) substring matching
- Infrascan/envscan: iterate sourceStore keys instead of walking disk
- All source reads via getSource() (LZ4 decompress from RAM)
- File hashes pre-computed during bulk load (zero re-reads)
Type system improvements:
- Overload resolution by parameter type (score_overload_match with type compatibility)
- Lambda return type inference (trailing return type + shallow body walk)
- Inline namespace normalization (strip __1, __cxx11, __gnu_cxx)
- Implicit conversions in overload scoring (const char* → string, numeric promotions)
- Virtual dispatch: prefer derived override over base method
- CRTP detection: template param → derived class mapping
- Range-for iterator protocol: map element fix + begin()/operator*() fallback
- Default argument support via min_params range matching
- Free function auto deduction: identifier eval order fix (function before type)
- decltype() return type parsing in c_parse_return_type_text
- Trailing return type syncs both return_type and return_types array
