- 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
Pre-decode opcode peek in myreq_handler() captures raw packet bytes for
OP_upgradeConfig before xce_decode() frees the capnp segment. Passes
raw bytes to xce_upgrade_config_req_extract_raw() to extract sha256 and
config blob, then delegates to do_upgrade_config_with_bytes().
Removes Task 11 dependency. Phase 2 still gated by CONF_ENABLE_UPGRADE_CONFIG.
Replaces -ENOSYS stub with:
- connect_ssl_raw() helper (non-blocking connect + poll + SSL handshake,
checks ha_is_primary() between iterations for early promotion exit)
- xce_replconfig_req_ssl() to send OP_replConfig request
- xce_replconfig_reply_ssl_decode() to receive and decode reply
- SHA-256 integrity verify (retry on mismatch with -EBADMSG)
- conf_save_config() atomic disk write to workdir/name/conf/
- load_primary_config() to reload cluster_config from newly saved file
Standby can now fetch ClusterConfig from primary on startup.
Replaces blocking pthread_join() per thread with a CLOCK_MONOTONIC
deadline + 5ms poll loop. CONF_PUSH_TIMEOUT_MS (500ms) now enforced.
Matches design §6.3 aggregate timeout guarantee.
- Add done field to push_ctx_t; push_thread sets it on exit
- Add static wait_all_with_timeout() before push_config_to_standbys()
- Wire push_config_to_standbys() to use wait_all_with_timeout()
- Add #include <stdatomic.h> to config_repl.c
- Guard push_ctx_t local typedef with #ifndef XCE_TESTING
- Expose push_ctx_t and wait_all_with_timeout_for_test() in header
under XCE_TESTING for unit test access
- Add test_wait_all_with_timeout_slow_threads (timeout fires, acked=0)
- Add test_wait_all_with_timeout_fast_threads (all complete, acked=3)
- Update design doc §6.3 with actual implementation signature and
5ms poll interval note
load_primary_config() reads from workdir/name/conf — conf_save_config()
was writing to workdir/conf. Latent bug: would have corrupted upgrade
restart cycle once Task 11 wired the upgrade path.
Update all conf_read_current_filename, conf_get_saved_tag, and
conf_check_stale calls in the test suite to use the corrected
effective_dir (workdir/name) path structure. Add new test
test_conf_save_config_path_consistency that explicitly verifies the
written path matches what load_primary_config() reads.
- create_lost_and_found(): provide hostattrs_t so makeWorker succeeds
- collect_queues/collect_workers (dataex.c): skip lost_and_found sentinel
so it is never pushed to apiserver or scheduler
- mark_worker_unavail(): reset hosttype/hostmodel to "unknown" and zero
all numeric attrs, then update resvals and slots — prevents stale
capacity from being visible while the host is down
- restore_worker(): apply the same attr reset on WAL recovery so
restored-but-unavailable workers advertise no capacity until reconnect;
also remove dead calloc() that was immediately overwritten by makeWorker
- Extract reset_hostattrs_unknown() helper to eliminate copy-paste
- Define XCE_LOST_AND_FOUND_NAME constant in config_repl.h; replace all
six raw "lost_and_found" string literals across config_repl.c and dataex.c
- handle_config_request(): primary-side handler sends up-to-date flag or
version_tag; SHA-256 integrity check guards against in-place file changes;
sha256/bytes fields left NULL pending Task 11 typemap shims
- fetch_config_from_primary(): standby fetch with exponential backoff retry
(20 attempts, 500ms..5s); falls back to saved config via load_primary_config();
do_one_config_fetch() stubbed (-ENOSYS) until Task 11 wires capnp over SSL
- handle_controller_join(): registers standby endpoint in ha.standby_endpoints
via zarray_store() for OP_upgradeConfig fan-out; sends success reply
- Moved load_primary_config() from myconf.c to config_repl.c so the unit test
binary (which links config_repl.c but not myconf.c) can resolve it
- load_primary_config(): resolves conf/current, reads raw bytes, computes
SHA-256 tag, decodes Cap'n Proto via load_cluster_config_from_file(),
checks reserved names, sets config_generation, checks staleness
- myconf_fini(): frees conffile and cluster_config (calls free_ClusterConfig)
- Remove static cf global from myconf.c; get_default_conf() now uses a
local struct cluster_configuration* via load_cluster_config()
- Add load_primary_config_for_test() under XCE_TESTING in config_repl.c
to test path resolution without triggering FATAL
- Add xce/cluster_def.h include to config_repl.c and test_config_repl.c
so cluster_t is complete when XCE_TESTING is active
- TDD: test_load_primary_config_missing_returns_error passes (18/18)
