Only 21 of 86 test_*.c group functions called their own nested
UNITY_BEGIN()/UNITY_END(). Each nested call reset Unity's global
NumberOfTests/TestFailures counters, so controller_test.c's final
`return UNITY_END();` -- the value meson test actually gates on --
only ever reflected whichever small window of tests ran since the
LAST nested reset, silently discarding pass/fail evidence for
everything before it (measured: 16 of 972 total tests in one run).
The same nested-BEGIN calls also caused PASS/FAIL banners to show
the wrong source file for tests in files that don't reset it
themselves (Unity.TestFile just carries over from whichever group
last called UNITY_BEGIN()).
Fix: replace every nested UNITY_BEGIN() with UnitySetTestFile(__FILE__)
(sets file attribution only, no counter reset) and drop the matching
UNITY_END(); add the same UnitySetTestFile(__FILE__) as the first
statement to the other group functions that had neither. The 2
genuinely standalone binaries (test_job_array_sched_push.c,
test_job_array_apiserver_push.c -- each has its own int main(), not
registered via controller_test.c's TEST() macro) are untouched.
Verified: single consolidated summary now reads
"972 Tests 0 Failures 0 Ignored OK", exactly matching the
ground-truth RUN_TEST call-site count across all 83 registered
group files (976 total minus 4 belonging to the 2 standalone
binaries). Every PASS/FAIL banner now names its own true source
file. Full xce-build.sh all regression pass clean (Ok: 9, Fail: 0).
No production code touched -- test-harness plumbing only.
With the dispatch flags flipped ON in-test, prove the three receiver-side
liveness properties (production defaults stay OFF):
- P1: while a snapshot (and config-push) transfer is parked in flight on the
slow lane, another endpoint's peer-control message is still processed
promptly on the vtask pool (different thread), with the transfer still
parked — the offloaded transfer does not block the drive path.
- P2: a peer-control ack (classified VTASK_LIVENESS) runs promptly even while
the pool is saturated to the LivenessAdmission reservation boundary with
REQ_BLOCK tasks (one more REQ_BLOCK fast-rejects with -E_XCE_NOT_READY,
proving real saturation). Narrowed to the liveness-dispatch-under-saturation
assertion; commit-advance itself is covered by the commit-engine tests.
- P3: while one endpoint's peer-control body is parked (holding a worker + that
ep busy), another endpoint's body runs concurrently on a different worker —
per-endpoint FIFO does not serialize across endpoints.
All deterministic (cond-var gates, bounded polls). Fixed a flaky teardown-race
hang (bug-1224): the tests released a parked vtask body then immediately called
the cancel-based vtaskmgr_fini while the just-released body was still unwinding
(P2's REQ_BLOCK bodies racing blk_lock teardown the worst). Fix adds end-of-body
completion counters polled to the full expected count before fini, so every
pool body has fully returned (worker idle) before the cancel. slowlane_fini is
graceful (join) so the lane side was already safe.
Verified: 5/5 deterministic isolated runs; full controller suite EXIT=0;
ASan-clean. Completes task 3.4 (3.4a UAF fix + 3.4b tests); the production
flag-flip remains deferred to after the 4.1 partition soak + 4.2 regression
sweep.
