vote_request_thread connects to peers via SSL. iomgr was started before
election but c->ep was only registered with epoll inside cluster_start(),
which runs after election. The TCP connect succeeded (kernel accepts it)
but SSL_accept was never called server-side, so SSL_connect failed
immediately — both vote threads went to deny in <1ms and ctrl-a could
never win a quorum.
Fix: add cluster_register_listener() that wires c->ep into iomgr's
epoll watch. Call it from myapp_run() right after iomgr_start/vtaskmgr_start,
before election. cluster_start() still calls iomgr_monitor again
(idempotent via EPOLL_CTL_MOD).
- Probe all peers: any tag>0 -> defer_config_fetch=true; all-zero -> proceed;
none reachable -> exponential backoff 500ms->10s cap with WARN per attempt
- Wire into myapp.c: before ha_wait_for_heartbeat_or_timeout()
- Post-election: defer_config_fetch && CTRL_STANDBY -> fetch_config_from_primary()
- INFO log for all three bootstrap outcomes (Req 10.2)
- XCE_TESTING hook for probe mock; test_ha_bootstrap_support.c installs mock
- 9/9 bootstrap tests GREEN, 141/141 full suite GREEN
- Add --vcpus N argp option in main.c; store in myconf.vcpus
- Replace inline argp guard with validate_vcpus() call (returns -EINVAL for <=0)
- Add validate_startup_config() in startup_validation.c: returns 0; writes
deprecation warning into caller-supplied warn_buf when vcpus key present
- Wire validate_startup_config() into myapp_run() after conffile resolved;
emit WARN() if warn_buf non-empty (Req 4.4)
- Remove vcpus field from cluster_config_t (clusterconfig.h)
- Preserve capnp ordinal: vcpus @7 -> vcpusDeprecated @7: Void in controller.capnp
- vtaskmgr_init uses only myconf->vcpus with hardcoded default 8
- Add stub C types in typemap.h for capnp schema extensions from task 1.1
- 96 tests pass
- myapp.c: capture am_i_primary() into is_primary (avoids redundant
second probe call); after load_primary_config() succeeds, record
CTRL_PRIMARY role via atomic_store_explicit so cluster_init_phase2()
sees the correct role (ha_init() defaults to CTRL_STANDBY)
- myapp.c: add #include "ha.h" for CTRL_PRIMARY, atomic_store_explicit,
and memory_order_release
- cluster.c: cluster_init() wrapper now calls cluster_fini(c) before
returning on create_ssl_context failure, hook failure, and
cluster_init_phase2 failure — prevents SSL ctx and phase1 resource leak
