deploy-ha.sh no longer takes a <data-dir> argument or --build-config
flag. Every deploy now generates a fresh self-signed TLS cert/key
(openssl, RSA 2048, 10y validity) directly into the deploy dir's
certs/, and builds cluster.bin directly into controller/ctrl-1/conf/
via xceadmin -- no intermediate staging directory, nothing preserved
across runs. run-ha-soak.sh (/xce-test-ha) updated to match: dropped
its own XCE_HA_DATADIR-based precondition entirely. Updated 4 callers
(run-ha-soak.sh, test-heartbeat-tolerance.sh, test-commit-durability.sh,
both xce-deploy-ha/xce-test-ha SKILL.md docs).
Separately: xcecommon.wire.connect() was loading a client-side TLS
cert, diverging from the real reference client -- netio.c's
create_ssl_context() presents no certificate at all when acting as a
client (cert_file/key_file both NULL, bare TLS_client_method()).
Fixed connect() to match, and since nothing else consumed cert_dir
(verify_mode=CERT_NONE throughout, no CA check either), removed it
end-to-end: discovery.follow_redirects(), push.push_config()/
probe_config(), and the --cert-dir CLI flag.
Server-side cert loading (mock TLS test servers) is unaffected --
moved into a shared session-scoped tls_certs fixture (new
tests/conftest.py, openssl-generated) replacing 3 duplicated
REPO_HA_DATA_DIR/skipif blocks. Net result: those tests no longer skip
under a hermetic nix build sandbox (which never had ha/data/) --
verified 165/165 passed, 0 skipped, via both meson compile and a full
nix build --option sandbox false .#xcecore_debug rebuild (previously
128 passed / 37 skipped there).
ha/data/{xce.crt,xce.key} removed from git tracking. Requirements
2.3/2.4 and 8.3/8.4/8.5 marked superseded in requirements.md with
dated correction notes.
deploy-ha.sh's --build-config path (task 4.2) pointed at
src/xceadmin/.venv/bin/xceadmin, broken by today's meson/nix rewiring
(xceadmin no longer builds a venv there). Fixed to search the meson
build dir (xce.build/build.release/build.dbg), a nix-installed
result/bin, then PATH.
/xce-deploy-ha's SKILL.md never mentioned xceadmin or --build-config
(predates task 4.2) — documented both.
/xce-test-ha's run-ha-soak.sh hard-required a pre-existing cluster.bin
under ha/data/, exit 2 if missing, with no xceadmin path at all. Now
always builds cluster.bin fresh from src/configs/*.yaml via xceadmin
before every soak run, same resolution order as deploy-ha.sh.
ha/data/cluster.bin is no longer a checked-in fixture: removed from
git tracking and gitignored. It was stale relative to xceadmin's
output anyway (different hash from a different, older generation
path) -- the xceadmin-built one matches the known-good golden-fixture
hash from admin-config-tool task 5.4.
Add --build-config (parsed anywhere in the arg list) that rebuilds
<data-dir>/cluster.bin from configs/ via the venv's xceadmin before
deploying; a missing cluster.bin auto-builds the same way even
without the flag. An existing cluster.bin with no flag passed is
left byte-for-byte untouched, matching prior behavior. xceadmin and
the configs source are resolved relative to the script's own
location, not the caller's CWD.
Verified live: missing-file auto-build, untouched-when-present (same
mtime/SHA), and forced rebuild reproducing byte-identical output.
Election protocol fixes validated against raft.tla invariants:
- ha_init_raft(): one-time raft state init at startup (re-init would lose
durable election progress); n_peers = full cluster size including self
- handle_request_vote(): higher-term step-down moved BEFORE the role gate
(split-brain fix); standby vote-deny now requires a live primary control
channel (primary_ctrl_fd >= 0) AND a fresh heartbeat
- ha_heartbeat_is_fresh(): derive freshness from ha->last_activity (the
field production actually writes); the orphaned last_heartbeat timespec
had no production writer, leaving the vote-deny gate inert (bug-337);
field removed from ha_state_t
- handle_request_vote(): restore same-candidate idempotent re-grant —
deny only a DIFFERENT candidate in the same term, matching raft.c and
Raft §5.2 votedFor ∈ {Nil, candidateId} (bug-338)
- raft_init(): restore voted_for_term alongside a persisted vote; leaving
it 0 allowed a double vote in the same term across a restart (bug-339)
- myapp_run(): leader_known check treats a vote recorded under this node's
own name as a self-vote — production persists the real candidate name,
the "self" placeholder only appears in test mode
- raft_on_vote_request(): leader steps down on higher-term vote request
instead of denying it
Tests: test_proto_H6_restored_vote_blocks_second_vote added; H1 restore
assertion strengthened; test_ha_vote_gate.c driven through last_activity +
primary_ctrl_fd (the real production fields). Full /xce-build all green
(lib + controller + scheduler + Go suites, 0 failures, ASAN clean).
deploy-ha.sh: start.sh now forwards extra args to the controller binary.
- ha.c: add raft_cb_trace callback wired to s_real_cbs.on_trace; emits
RAFT[pN] term=T event=E at DEBUG3 level, visible with -vvv flag.
- ha.c: repl_ack_decode_and_dispatch now silently drops OPCode_nop and
OPCode_reply instead of WARNING — heartbeat NOP replies from standbys
arrive on promoted endpoints and are expected.
- deploy-ha.sh: fix --vcpu -> --vcpus; add \$VERBOSE passthrough so
start.sh respects VERBOSE=-vvv from the environment.
