The test proved parallelism with a fixed 10000-iteration busy-wait, hoping workers would overlap — but on a loaded CI runner a worker could finish before the next thread started, leaving concurrent_max=1 (a flaky FAIL, seen on ubuntu-latest). Spin until at least two workers are concurrently active (bounded, with an early exit once the overlap is proven) so the parallelism invariant is demonstrated deterministically instead of by timing luck.
Add scripts/check-no-test-skips.sh (run from lint) which fails the lint phase on any plain SKIP() or direct tf_skip_count manipulation; only SKIP_PLATFORM() (for genuinely platform-specific tests) is tolerated. Add FAIL() and SKIP_PLATFORM() helpers to the test framework and convert the remaining SKIP()/perf-gated skips across the suite into pass-or-fail assertions, so a suite that cannot meet its preconditions reports a red failure instead of a silent skip.
- parallel_for_actually_parallel: skip on single-core CI runners
instead of failing (assertion requires >= 2 concurrent threads)
- Fix mkdir -p → portable mkdir in test_ui.c config tests
- Skip store_dump_to_file and cli_find_cli_on_path on Windows
(temp file path handling and PATH search need porting)
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.
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.
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.
