- 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
Three identical static copies (controller, worker, scheduler) replaced
with a single xce_parse_peers() in src/lib/cluster.c.
The libxce version is the canonical implementation: stores the logical
name from 'name=host:port' syntax so daemons on the same dev host can
identify themselves by name rather than IP address.
- xce_candidate_t gains name[] field for logical peer identity
- parse_peers stores name prefix before '=' (empty when omitted)
- cluster_init matches own identity by name first, hostname as fallback
enabling multiple controllers on the same dev host via
--peers ctrl-1=10.0.1.1:7000,ctrl-2=10.0.1.2:7001
- myconf_t gains peers_cfg (xce_cluster_config_t) populated from --peers
- controller/main.c: parse --peers host:port,... via argp; ca_cert_path
auto-derived from workdir/certs/xce.crt (no --ca-cert flag needed)
- cluster_init: derive my_priority from position in peers list (index 0 =
primary); fall back to 0 when --peers not given (single-node mode)
