- 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
- sem_timedwait on heartbeat_seen semaphore with CLOCK_REALTIME deadline
- deadline = now + election_timeout_ms + xorshift64 jitter
- Returns CTRL_STANDBY on heartbeat arrival (calls ha_do_demote)
- Returns CTRL_ELECTING on timeout (caller drives election)
- Allows OPCode_heartbeat through dispatch gate in CTRL_INIT state
- 3 new unit tests: standby-on-heartbeat, electing-on-timeout, gate-allows-heartbeat
- 24 Tests 0 Failures in test_ha_startup suite
- errnox.h: add E_XCE_NOT_READY and E_XCE_STANDBY error codes with
extern int XCE_ERR_NOT_READY / XCE_ERR_STANDBY runtime variables
- ha.h: declare ha_dispatch_gate(ha_state_t *, int opcode)
- ha.c: define XCE_ERR_* variables; initialize heartbeat_seen semaphore
and primary_ctrl_fd = -1 in ha_init(); sem_destroy in ha_fini();
implement ha_dispatch_gate() with allowlist for CTRL_INIT/CTRL_ELECTING
(only OP_requestVote and OP_probeConfigTag pass) and CTRL_STANDBY
(replication, election, and housekeeping ops pass; primary-only ops
return -XCE_ERR_STANDBY)
- cluster.c: wire ha_dispatch_gate() in myreq_handler() before opcode
switch; gate failure sends error reply and returns early
All 393 unit tests pass. Satisfies requirements 1.3 and 1.4.
- Implement validate_peer_count() in startup_validation.c: -EINVAL for even N>1
- Implement validate_cert_files() with err_buf output: access() check, writes
missing path into err_buf, returns -ENOENT
- Wire validate_peer_count() in main.c after peer list parse; fatal exit on fail
- Wire validate_cert_files() in main.c before SSL init; fatal exit on fail
- Fix ASAN leak: SSL_CTX_free in ha_fini() with NULL guard
- Fix double-free: null c->ha.ssl_ctx in cluster_fini() before ha_fini(),
so iomgr_fini() retains sole SSL_CTX ownership (design per ha.h comment)
- All 96 tests pass; all 12 ha_startup tests 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
RED-phase tests for 4 startup validation functions — all fail at link time
because the functions under test do not exist yet:
- validate_peer_count: even N>1 returns -EINVAL, odd N returns 0
- validate_cert_files: missing cert/key returns -ENOENT with full path
in err_buf output param (asserted via strstr)
- validate_vcpus: vcpus<=0 returns -EINVAL, positive returns 0
- validate_startup_config: vcpus key in config returns 0 (not fatal)
and writes deprecation text into warn_buf (asserted via strstr)
Replace monolithic add_worker with three focused functions:
- apply_join_state (static under production, exported under XCE_TESTING):
shared status/resource update called by both create and rejoin paths;
clears XCE_WORKER_UNAVAIL, applies hconfig overrides, updates resources
- init_worker: first-time join path via makeWorker + apply_join_state
- rejoin_worker: reconnect path with explicit admin-bit preservation
(XCE_WORKER_ADMIN_MASK = LOCKEDU|CLOSED|HIDDEN|CLOSED_BY_ADMIN)
Also makes find_matched_hostconfig non-static so join.c can call it
via the extern declaration already in worker.h.
Removes add_worker (no longer declared in worker.h, no callers).
All 7 tests in test_worker_join pass:
apply_join_state (clears UNAVAIL, hosttype override, resource values),
init_worker (creates entry, returns correct idx),
rejoin_worker (updates attrs/ep, preserves admin bits).
