Add void (*on_connected)(endpoint_t *ep) field to endpoint_t with
endpoint_set_on_connected() helper. io_handler fires it exactly once
immediately after ssl_handshake_done=1 then nulls the pointer.
Enables ha_start_election_async to send OP_requestVote as soon as
the TLS handshake with a peer completes — no blocking SSL_connect.
6 new unit tests pass; controller suite 1/1 OK.
Add millisecond-granularity delay_task_ms() to delaymgr using
clock_gettime(CLOCK_MONOTONIC) for deadline computation. Extends
delay_task_t with nextrun_ts field; delay_worker distinguishes
ms-tasks from second-tasks via non-zero nextrun_ts. Backward
compatible with existing delay_task callers.
4 delay tests pass (2 new: tolerance and invalid-args).
Provides the timeout primitive for election and committing watchdogs.
sel_key_cmp_fn compared keys with memcmp on the whole sel_node_key_t
struct, including the 4-byte padding between type and op1. The stack-
allocated search key in gc_sweep_select_nodes can have different padding
bytes than the heap-allocated copy stored by key_add, causing key_del
to miss the entry and leave a dangling pointer in the CSE intern table.
Replace memcmp with field-by-field comparison on type, op1, op2.
Also fix GC sweep tests that asserted pointer inequality after re-intern:
calloc may lawfully reuse the freed address, so pointer inequality does
not reliably indicate a successful sweep. Track the swept node's
node_id before freeing and assert the re-interned node gets a fresh id.

Worker (P2.5-5):
- Added parse_peers() static helper to src/worker/src/main.c
- Switched getopt to getopt_long to support --peers and --ca-cert long options
- When --peers is given: parses into xce_cluster_config_t, calls
xce_cluster_config_validate(), logs INFO with candidate count/identity/ca_cert
- If validation fails: prints clear error and exits(1)
- WARN logged when candidates_count > 3
- Backward compatible: no --peers falls back to existing single-controller path
Scheduler (P2.5-6):
- Added parse_peers() static helper to src/scheduler/src/main.c
- Extended argp struct with --peers (-P) and --ca-cert (-C) options
- Same validation/logging pattern as worker
- Backward compatible: no --peers falls back to existing single-controller path
Tests (new):
- src/lib/testsuite/test_cluster_parse.c: 8 unit tests for parse_peers logic
(single entry, multiple entries, no-name format, empty/null/missing-port errors,
name-stripped correctly, MAX_HA_CANDIDATES cap respected)
- Registered in test.c and meson.build
- All 8 tests GREEN; 3 pre-existing failures in unrelated GC/CSE tests unchanged
- hook_item_t.fn changed to _Atomic hook_fn_t (C11 stdatomic)
- xce_disable_hook(): atomically stores NULL into the slot fn field;
returns 0 on success, -ENOENT if fn not found, -EINVAL on bad args
- xce_add_hook(): scans for NULL (disabled) slots before allocating;
uses atomic_store_explicit(release) when writing fn pointer
- xce_run_hooks(): atomic_load_explicit(acquire) + NULL guard so
disabled slots are silently skipped without disrupting the loop
- Add src/lib/testsuite/test_hooks.c with 3 TDD tests:
test_disable_hook_stops_invocation
test_disable_hook_returns_enoent_if_not_found
test_add_hook_reuses_null_slot
- Register test_hooks in meson.build and test.c runner
Required by ha_demote_to_standby() to atomically disable persistence
hooks when the controller steps down from primary, preventing unbounded
hook list growth across promote/demote cycles (resolution A6-015,
A7-004, A7-016).
Add kvtab_foreach walk primitive (P0-14) to kv.c/kv.h, then implement
kvmgr_capture_keys in kvmgr.c that deep-copies all key→index mappings
into a malloc'd slot_key_t[] array safe to read after the write lock is
released during checkpoint serialization (Part 3.8).
Key design points:
- Both kvtab_foreach and kvmgr_capture_keys take var (RTTI data pointer)
and use RTTI_DATA_TO_OBJ internally — the RTTI framework's makeInstance
returns the data region pointer, not the meta_obj_t header pointer
- String keys are copied via strncpy into slot_key_t.key[XCE_MAXNAME_LEN]
- Integer keys are formatted as decimal strings via snprintf
- Two-pass approach: count live entries first, allocate, then fill
- Tests cover string kvmgr (3 entries), empty kvmgr, and deep-copy safety
- 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.
- 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.
