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)
