Implements Phase 1 of .kiro/specs/external-license-resources/ (design.md):
externally-reported license pools pushed by a dedicated daemon through the
existing resval pipeline, with EXTERNAL-aware admission arithmetic.
Wire & controller:
- controller.capnp HostRole.extres (@5, appended); xce_join_req accepts it
- extres.c: HostRole_extres join table (endpoint+name, no workermgr slot),
leave cleanup; join.c/cluster.c dispatch
- opupd.c do_update_resvals: extres branch runs the resource hooks and
update_resval_list(c, NULL, ...) — host=="" entries route through
update_val_res' SHARED branch into c->sharedinst; per-entry -EPERM for
non-shared targets is logged, never fails the list
- worker.c update_val_res: NULL worker only writes SHARED resources
- cluster.c cluster_build_resources: rebuilt on resourceApplyDef (bug-1854)
— EEXIST-tolerant so definitions added by an activation register on a
RUNNING controller (bug-1973), and RES_APPLY_CHANGED updates definition
fields (valtype/ordtype/flags/interval) in place so a corrected config
heals a stale registration (bug-1974); seed_sharedinst_from_config skips
EXTERNAL pools (daemon-reported free counts only; seeding would fabricate
capacity while the daemon is down)
Scheduler:
- core_events.c RESVALS_DELTA: NULL/"" host marks a SHARED value and lands
in core->sharedInst via dup_val (bug-1585 ownership rule), mirroring
snapshot_load's host=="" precedent — previously WARN-skipped as unknown
worker
- resource.c unsatisfy_: EXTERNAL skips the inuse term
(F >= uncomit + wanted; F is already net of our checkouts)
xceesd (src/esd, new component):
- script collectors polled per source, debounce on unchanged values,
fail-open stale policy; pushes host=="" shared resvals over xcecli
- reconnect gap fix (bug-1975): with a stable value the debounce pushed
nothing and reconnects only fire inside a push — after a controller
restart the daemon sat on a dead connection forever; the main loop now
forces a full re-push when xcecli_is_connection_broken() (bug-1760
predicate) latches
Config/mapping:
- resources.yaml: extlic sample (location: [external])
- mapping.py: RESOURCE_FLAG_EXTERNAL (0x10) + location:["external"] mapping;
xceadmin tests
Tests (TDD, red->green per fix): test_extres_resvals.c (join+resval
pipeline), test_config_resource_reconcile.c +2 (register past EEXIST /
hot-apply changed definition), test_core_events.c +131 lines (shared DELTA
landing), mapping tests. Suites: controller 1358/0, scheduler 100/0,
esd 7/0, lib 1/0; check-no-fork covers src/esd.
Live t1 E2E: config gen=15 push -> xceesd push extlic=4 lands in
sharedinst -> rusage[extlic=3] job RUN; second job PENDs at free=1;
release re-admits it; controller restart -> forced re-push restores the
value and admission resumes. Full precommit job verification passed.
