- 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).
