From 2b28f26a3aebfd8fabe9ebcf037668e818d0d749 Mon Sep 17 00:00:00 2001 From: Fujii Masao Date: Sun, 27 Jul 2025 13:59:08 +0900 Subject: [PATCH v2] Add regression test for background worker restart after crash. Previously, if a background worker crashed and the server restarted with restart_after_crash enabled, the worker was not restarted as expected. This issue was fixed by commit b5d084c5353, which ensures that background workers without the never-restart flag are correctly restarted after a crash-and-restart cycle. To guard against regressions, this commit adds a test that verifies a background worker successfully restarts in such a scenario.
