test(legendcoveragecheck): run its calls in a pool, heaviest first, and report timeouts as timeouts by joyful-ii-V-I · Pull Request #394 · redhat-et/ripwire

joyful-ii-V-I · 2026-10-13T16:18:44Z

test/legendcoveragecheck.sh hit its 1200 s budget on the macOS plain shard 4/4 twice in three days (the PR runs of #385 and #393). Gate-only change; no source change, and every PASS/FAIL/COUNTS line is byte-identical.

Why it was slow: 176 calls, all already on the warm per-root cache, run strictly one after another. The cost was the serial schedule, not cold parses. The two --pr-context=HEAD~30 calls alone took ~105 s and ~50 s (about 40% of the run).

The change:

One shared worker pool (LEGENDCOV_JOBS, default min(4, cpus)) runs the heaviest calls first; results are judged in the original roster order, so no row, assertion or message changes. --doctor runs serially after the pool.
Each call has its own 600 s budget (LEGENDCOV_CALL_TIMEOUT); a timeout or a signal prints its own TIMEOUT/ERROR FAIL line instead of a misleading verdict (same rule as the cppqualcheck fix in Hygiene after v0.6.7: cppqualcheck reports timeouts as timeouts, #382 review notes, CONTRIBUTING map rows #393).

Evidence:

Local wall 322/316 s → 143/138 s (2 interleaved runs each, Release build); output byte-identical on both pairs, ALL PASS.
Mutations still fail: an injected undefined attribute fails (A) and (G); LEGENDCOV_CALL_TIMEOUT=3 prints 16 TIMEOUT FAIL lines and exits 1.
gateexitcheck and manifestcheck pass; --quality-delta gates 0.

Found along the way (not in this PR): src/gitmine.h cochangePartners rebuilds StaticIncludeCoupling once per changed file, about 87% of --pr-context's time. Hoisting it out of that loop is a separate source change, tracked for the next integration train.

Summary by CodeRabbit

Tests
- Legend-coverage checks now run roster commands concurrently, with heavier calls prioritized and doctor checks run afterward.
- Timeouts, launch errors, and signal terminations are reported as failures instead of empty results. Dropped-legend probes use the same handling.
- Worker count and per-call timeout can be configured. Existing roster-order verdicts and handling of nonzero command exits remain unchanged.

…l timeouts The gate ran its ~170 independent read-only calls one at a time: 394 s on the dev machine, and over its 1200 s budget (rc=124) on the macOS plain shard twice in three days. Two calls (--pr-context=HEAD~30, with and without a budget) are ~40% of that by themselves; that cost is inside ripwire, not the gate. - The roster and the (E) dropped-note sweep share one runner: a thread pool (LEGENDCOV_JOBS, default min(4, cpus); 1 = the old serial run), heaviest calls submitted first. Every row still runs its own command once and is judged in roster order as before. --doctor, whose answer reads the cache directory, runs serially after the pool drains. - Every call has a budget (LEGENDCOV_CALL_TIMEOUT, default 600 s). A call that times out or dies on a signal prints its own TIMEOUT/ERROR FAIL line naming the call, instead of an empty document read as silent or a partial one judged for gaps. A non-zero exit code is judged as before. No assertion, roster row, floor or expected count changed. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

📝 Walkthrough

The legend coverage script now runs roster and dropped-legend calls through a configurable Python thread pool. It records timeouts, launch errors, and signal termination as failures, while preserving roster-order verdict processing.

Changes: Legend coverage checks

Layer / File(s)	Summary
Concurrent roster execution `test/legendcoveragecheck.sh`	A shared Python runner executes prioritized roster calls concurrently and runs designated calls after the pool drains. The roster gate reports recorded failures and fails if it cannot read the call-outcome file.
Pooled dropped-legend probes `test/legendcoveragecheck.sh`	Each dialect’s tight, wide, and margin-budget probes use pooled calls. Call failures are reported for that dialect, and the headroom check uses the fetched margin-budget document.

Priority: ⬇️ Low

Estimated code review effort: 3 (Moderate) | ~20 minutes

Change: Other

Suggested reviewers: barefootski

Merge Risk: 🔵 Low · up to cdd75

The gate still fails on these errors, but some call-specific diagnostics can be lost. These are bounded risks rather than a reason to block merging.

Disposition update: 0250675 merges main (a87470c, #395) into this branch so CI runs with the faster --pr-context. The previous run timed out on that call on a slow macOS runner. No change to this PR's own diff. Commits after the reviewed head cdd75d4: 03c29ef (the CodeRabbit fix) and 0250675 (this merge).
