- 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)
- Add HA_DEFAULT_* constants to ha.h; use them in cluster_init()
- Strip stale task-label comments (P1-3a, P1-5, P1-6, P3-6 refs)
- Remove self-documenting 'Step N:' annotations from ha_do_promote/demote
- Rewrite stale forward-reference notes as current WHY comments
- Remove resolved TODO P0-8b from cluster.c
Add terminal-state constants and GC retention predicates for the
checkpoint xzarray_thaw() GC pass:
- types.h: add JOB_STAT_TRANSIENT (0x400), XCE_WORKER_HIDDEN (0x00200000),
QUEUE_STAT_HIDDEN (0x0100)
- persist.c: implement job_is_terminal(), job_should_retain(),
worker_should_retain() — placed here so the unit test binary
(which links only persist.c) can access them without RTTI deps
- persist.h: declare the three GC predicates; include xce/types.h
- worker.c: set dead_since = time(NULL) in mark_worker_unavail()
when dead_since is not already set
- cluster.c: add TODO P0-8b marker on zarray_del endpoint cleanup
- meson.build: register test_gc_retention.c; raise test timeout 60→120s
- testsuite/test_gc_retention.c: 19 tests covering job_is_terminal,
job_should_retain (TRANSIENT TTL, terminal TTL, non-terminal always
retained), and worker_should_retain (HIDDEN/UNAVAIL/healthy/zero
dead_since); all pass (63 total, 0 failures)
- Rename `precision` field to `precision_ms` in delaymgr_t struct (delay.h)
- Replace `sleep(mgr->precision)` with `nanosleep()` for 10ms granularity (delay.c)
- Add `#include <time.h>` to delay.c (already in delay.h)
- Update delaymgr_init() to store precision_ms parameter
- Update all call sites: cluster.c (2→200ms), controller/testsuite/test.c (2→2000ms),
lib/testsuite/test_delay.c (1→1000ms)
- Add TDD test test_delaymgr_precision_ms_field verifying field exists and stores correctly
- delay_task() delay parameter remains in seconds; only sleep granularity changes
Add the full call chain for host control operations from the Go API
server through the C library to the controller:
- schema/controller.capnp: HostControl struct + hostctrlmsg @21
in Request.body union
- include/typemap.h: xce_hostctrl_t* hostctrlmsg in body union
(placed after @20 clrpreasonmsg, matching capnp ordinal)
- include/client.h, xceapi.h, request.h: declarations for
xcecli_hostctrl, xce_hostctrl, xce_hostctrl_req
- lib/client.c: xcecli_hostctrl (validate + delegate to xce_hostctrl)
- lib/xceapi.c: xce_hostctrl (validate ctx state + send + wait reply)
- lib/request.c: xce_hostctrl_req (validate hostname/empty/nil,
accept only HOST_OPEN/HOST_CLOSE, reject HOST_TAG/UNTAG)
- lib/helper.c: Request_body_hostctrlmsg cases in
xce_request_body() and xce_request_msg_name()
- controller/cluster.c: OPCode_hostcontrol dispatch
- controller/include/cluster.h: do_hostcontrol_op declaration
- controller/worker.c: do_hostcontrol_op + fix pre-existing
goto-clean bug in worker_ctrl that leaked write lock and
reference on HOST_OPEN/HOST_CLOSE no-op paths
TDD: 8 xce_hostctrl_req validation tests (null ep, null ctrl,
null/empty hostname, HOST_DO_NONE no-op, HOST_TAG/UNTAG reject,
negative action reject, HOST_OPEN/CLOSE accept via xce_request).
116/116 xcelib tests pass. CGO_ENABLED=0 Go backend tests pass.
