From af099dca3e52fbbf060d9ce59c8d5fdd3c0199e1 Mon Sep 17 00:00:00 2001 From: Rongsong Shen Date: Wed, 24 Jun 2026 10:17:11 +0000 Subject: [PATCH] =?UTF-8?q?test(ha-convergence-recovery):=20close=20Task?= =?UTF-8?q?=208=20=E2=80=94=20live=20/xce-test-ha=208-round=20PASS?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Ran the live 3-node E2E (the last open task). Result: PASS: 8 rounds, 30 jobs submitted, zero job loss; all 3 nodes led (ctrl-1,ctrl-2,ctrl-3) (exit 0) Live-covered: kill-primary -> promoted standby owns all confirmed jobs (zero loss across 8 failovers, jobs 3->30, expect-job ok each round); restart ex-primary -> converged rejoin, 3-of-3 each round, no phantom jobs; deterministic leadership coverage (ctrl-3 forced via RequestVote-freshness fence). The soak also served as the live regression for bug-1077 (~40 failover client round-trips, no SEGV) after rebuilding the controller (the deployed binaries predated that fix). Not exercised live (remain unit-covered, tasks 2/4/5): withhold-ACK barrier single-outcome (test_demotion_convergence) and isolate/heal quorum-WARN (test_convergence_verification). All 8 tasks now [x]; spec closed.
