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.
Adds 3 targeted tests after confirming tasks 2.1/2.2 already cover
most of this task's observable criteria:
- one-entry/one-continuation swept across sizes {2,3,100,1000}
(existing coverage only tested size 5)
- payload-size boundedness at the real idgen()-enforced ceiling
(MAX_ARRAY_IDX+1 = 32768), plus an absolute byte-cap assertion
(existing coverage only compared 2 vs 10000)
- array_size==1 baseline: explicit WAL-byte readback proving the
entry type is WAL_JOB_SUBMIT (not WAL_JOB_ARRAY_SUBMIT) and the
payload decodes via struct Job, not struct JobSubmit (existing
coverage only proved "old tests still pass" implicitly)
No production code changed -- test-only.
Task 2.3 of job-array-single-wal-record.
Adds persist_submit_job_array_async(): encodes one JobSubmit-shaped
payload (base jobid, array size, one shared spec), appends exactly
one WAL_JOB_ARRAY_SUBMIT entry, and registers exactly one commit
continuation regardless of array size -- reuses the existing
job_commit_adapter_ctx_t/job_commit_resolve_adapter machinery, no
per-element loop. Not yet wired into handle_jobsubmit (task 2.2).
Also fixes a test-helper bug (WAL offset back-computed from the
post-append cursor, only valid for zero-payload entries) that
corrupted state across tests when exercising a nonzero-payload
array-submit entry.
Task 2.1 of job-array-single-wal-record.
Adds the array-shaped WAL entry type (distinct from WAL_JOB_SUBMIT,
value 11 in the unused WAL_JOB_* gap) and classifies it WAIT-mode via
wal_classify, matching the single-job type's commit-barrier semantics.
No dispatch/apply wiring yet -- foundation for task 2.x/3.x.
Task 1.1 of job-array-single-wal-record.
Wires do_upgrade_config_with_bytes to append WAL_CONFIG_MARKER through
raft_log_append (live term-stamped consensus record), demotes committed_config_tag
to a non-authoritative cache, and derives the committed config from the latest
committed marker. Preserves the derive across checkpoint compaction via an optional,
backward-compatible config-ref tail in the snapshot sentinel.
Root cause (found via live 3-node E2E + a verification test): lsn was 0-based
(hdr.lsn = current_lsn++ from current_lsn=0), and 0 was overloaded as a
sentinel, causing three cold-start defects on a freshly-promoted leader:
- the first WAL entry (own-term promotion NOOP at lsn 0) was structurally
uncommittable: commit_advance_locked only stores when cand>cur and
committed_lsn starts at 0, so lsn 0 can never advance it;
- commit_set_writable_lsn(noop_lsn=0) set writable_lsn=0, which wait_done
reads as 'gate off' — the own-term safety gate was a no-op on the first leader;
- bug-543 (WAL hole): ha_stream_wal_to_standby filters hdr.lsn>standby_lsn;
a fresh empty standby reports standby_lsn=0 (ambiguous 'empty' vs 'has lsn 0'),
so lsn 0 failed 0>0 and was dropped -> non-contiguous standby WAL.
Fix: a fresh persist store initializes current_lsn=1, reserving lsn 0 as the
none/empty sentinel. The first real entry is lsn 1 -> committable (0->1),
writable_lsn=1 -> gate effective, and standby_lsn=0 unambiguously means 'empty'
so catch-up streams from the first entry with no hole. persist_recover is
data-driven (current_lsn=max(hdr.lsn+1)), so existing on-disk WALs and non-fresh
recovery are unaffected; the change only sets the base for brand-new stores.
No wire/capnp change.
Verification: test_coldstart_lsn0 drives the real commit engine + real streamer
and proves H1 (first entry commits 0->1), H3 (gate effective + blocks when
committed<writable), H4 (empty-standby catch-up is contiguous [1,2], control
standby_lsn=1 gets only [2]). Full controller suite green under ASAN. Tests that
relied on the lsn-0 base were shifted (several strengthened); commit.c /
config_repl.c / ha.c / wire format untouched.
Owning specs: ha-commit-engine / ha-wal-replication / persist. Follow-up:
sweep stale lsn-0 comments (repl.c:429-436, persist.c:1055-1075/1240-1243/1296).
configAck branch: per-push majority (acked_config_lsn >= push_tag,
1+count > n_peers/2 over r->ce->n_peers, n_peers<=1 immediate,
ce==NULL -EINVAL); legacy >0 counting and n_active==0 shortcut dead.
push_config_to_standbys returns the barrier result; upgrade failure ->
send_upgrade_error (rc forwarded), no success ACK, no restart,
committed_config_tag success-only.
Remediation r1 (two CRITICAL review findings):
- F1: wire production config-ACK ingestion — replconfigpushreplymsg
decode branch in repl_ack_decode_and_dispatch -> repl_on_config_ack
on the promoted-vote ep; + defensive cluster.c OPCode_reply case.
Closes the unlanded half of ha-config-bootstrap 8.1; without this the
barrier would brick every multi-member config upgrade. No schema change.
- F2: keep the barrier off the iomgr thread — export
push_config_transport_only (non-blocking) for the 5 ha.c + join.c
streaming sites; barrier path now vtask-only (do_upgrade_config).
Wire-path test drives real capnp ACK bytes through the production decode
branch. 30/30 rollout, 6/6 repl_majority, 46/46 config_repl; census 0
FAIL; pre-existing fixture leak only (less than baseline).
4 RED carriers (notify/update/setpreason/clrpreason must be admitted
without quorum — currently NOT_READY, the bug-396 hole) + 2 pins (six
request opcodes stay rejected; quorum-present admits all ten). Census
494 = 488 + 6; exactly 4 FAILs.
7 cases: two covered short-circuits, timeout with committed_lsn
unmoved, covering-ACK release, sync_timeout_ms fallback (bounded both
directions), n_peers=1 standalone, NOT_READY passthrough via cap
saturation. Watermark resolved to current_lsn - 1 (design's literal
phrasing unsatisfiable per persist.h:71 invariant) with off-by-one
killing power both ways. 15 tests / 7 RED; suite baseline zero.
