Build configcompare_paths(), an offline sibling to snapdiff/walcompare that
recomputes each member's active-config sha256 fresh from its own on-disk
workdir/name/conf bytes and reports identical vs. divergent (Req 4.2).
Wire it as a cmd_configcompare CLI subcommand in test.c, matching its
siblings, after review caught it shipped as an unreachable library function
in round 1.
Extend snapverify to match the current on-disk checkpoint format: bump
SNAP_FORMAT_VERSION to 2, replace the stale raw queue-frame decode with the
capnp length-prefixed walk, add host-frame and config-bytes-section
structural walks, and decode (not just presence-check) the header's
cfgref tag/sha. Without this fix snapverify rejected every checkpoint
written by the current codebase.
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.
ha_send_snapshot_to_standby ignored the network send's return value in its
chunk loop, silently truncating a transfer on a mid-stream error while still
logging "complete" (bug-1386). Fixing the silent drop exposed a second,
independent bug in the same pipeline: ha_handle_snapshot_chunk appended
received chunks in arrival order instead of at their wire-carried
chunk_offset, so out-of-order delivery across the vtask pool corrupted the
reassembled file even though every chunk's bytes were individually correct
(bug-1389). Fixed by checking every fallible call in the send loop and
switching the receiver to pwrite-at-offset with a count-based completion
tracker.
Adds snapverify/snapdiff xce_test commands (offline checkpoint-file
structural validator and byte-level comparator) used to diagnose bug-1389 and
kept as standing diagnostic tools for future snapshot-transfer triage.
g_drive_async_configpush_offload flipped back ON after both fixes, validated
via 6-round chaotic + 3/3 force-snapshot soak (raft-drive-async task 3.3).
