From d937c1c1bb24115be0c6f83f60038c4f02de64b7 Mon Sep 17 00:00:00 2001 From: Rongsong Shen Date: Mon, 1 Jun 2026 15:31:15 +0000 Subject: [PATCH] feat(ha-heartbeat-liveness): role-based liveness reset in opcode dispatch (task 3.1) Replace fd-based guard in OPCode_nop with role==CTRL_STANDBY check. Add ha_on_heartbeat_received call to OPCode_hello ctrlhello path when standby. Satisfies Req 1.3 (any message resets deadline) and Req 4.1 (ctrlhello counts). 3 new dispatch guard tests added to test_ha_liveness.c. --- .kiro/specs/ha-heartbeat-liveness/tasks.md | 2 +- src/controller/cluster.c | 10 ++- src/controller/testsuite/test_ha_liveness.c | 95 +++++++++++++++++++++ 3 files changed, 104 insertions(+), 3 deletions(-) diff --git a/.kiro/specs/ha-heartbeat-liveness/tasks.md b/.kiro/specs/ha-heartbeat-liveness/tasks.md index 993ea8a..56d6409 100644 --- a/.kiro/specs/ha-heartbeat-liveness/tasks.md +++ b/.kiro/specs/ha-heartbeat-liveness/tasks.md @@ -39,7 +39,7 @@ - _Boundary: ha.c (primary heartbeat path, standby_ep_ctx_t)_ - [ ] 3.
