- Add in_cow flag + shadow/shadow_caps fields to xzarray_private_t
- Convert xzarray_item_t.inuse from bitfield to _Atomic _Bool; update
all read/write sites to use atomic_load/store_explicit
- Implement xzarray_freeze(): O(1) ptr swap, pre-grows active array
1.5x+16 to avoid realloc during COW, sets pos past shadow range
- Implement xzarray_thaw(): merges shadow into active (shadow wins only
for slots not updated during COW), supports optional retain_fn GC
- xzarray_get_vec(): falls back to shadow during COW so reads remain
valid between freeze and thaw
- Add COW guard assertion in xzarray_clear()
- Wire vfreeze/vthaw into xzarray_type interface
- Tests: 5 new COW tests all green; 4 pre-existing failures unchanged
- 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
rtti header already present at rtti-0.0.2 with vfreeze_fn_t, vthaw_fn_t,
retain_fn_t, and the two new slots in intf_varray_t. No header modification
needed.
Convert intf_varray_t compound-literal initializers in zarray.c and kvmgr.c
to designated style with explicit .vfreeze = NULL and .vthaw = NULL slots.
kv.c has no intf_varray_t initializer.
Add test_zarray_cow.c with test_freeze_thaw_slots_exist which verifies the
struct layout has the slots accessible and that they are NULL until P0-2
wires the real implementations. Wire test into meson.build and test.c.
Full clean rebuild confirmed: 27/28 targets linked, no new test failures.
Only the 4 pre-existing failures remain.
- simple_num/simple_str: guard h->numvals/strvals NULL and idx out-of-range before array access
- eval_select_simple SEL_RESNAME: guard host->numvals NULL and idx bounds before deref
- eval_select_inner SEL_RESNAME (memoizing path): same NULL/bounds guards for numvals and strvals
- build_host_eval_ctx: return valid empty context (num_res=0, NULL arrays) instead of NULL when num_res<=0
- sched_meet_host_selection: remove empty_ctx stack hack; always call build_host_eval_ctx which now handles the zero-resource case cleanly
- Add gc_clear_marks(): iterates intern table and zeroes all gc_mark bits
- Rename static gc_mark_tree → public gc_mark_select_tree (no attribute((unused)))
- Remove Phase 6 guard (live_jobs != NULL early return) from gc_sweep_select_nodes
- Remove the mark-clear loop from gc_sweep_select_nodes; add (void) casts for now-unused params
- Declare gc_clear_marks and gc_mark_select_tree in resreq.h with protocol comment
- Add TDD test test_gc_clear_marks_exported verifying the exported primitives
- Prefix all existing gc_sweep_select_nodes(NULL, 0) call sites in test_select.c with gc_clear_marks()
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.

- Fix issue to xce_get() api cause client side crash
- add parse resreq section
- add rusage parser
- parse resreq with basic support alternative & compound, still miss select
