From fb257c50b3312ca40f05e1660199c88485288a97 Mon Sep 17 00:00:00 2001 From: Dmitrii Iurco Date: Wed, 10 Jun 2026 13:18:42 -0400 Subject: [PATCH] test: cover startup Caddyfile regeneration to prevent restart-loop regression Adds TestStartupCaddyRegen::test_startup_regenerates_caddyfile_first, asserting that _apply_startup_enforcement() calls caddy_manager.regenerate_with_installed([]) before any peer/iptables work. This pins the fix that ensures a stale on-disk Caddyfile (e.g. missing `admin 0.0.0.0:2019`) is overwritten at startup and cannot cause the health monitor to restart Caddy every few minutes. Also restores two displaced lines in test_health_history_maxlen_evicts_old_entries.
