From 4fddf8fc77496d9bb3b5fa8835f0e5ba9a5a9926 Mon Sep 17 00:00:00 2001 From: Richard van der Hoff Date: Mon, 11 Feb 2019 17:57:58 +0000 Subject: [PATCH] Infer no_tls from presence of TLS listeners Rather than have to specify `no_tls` explicitly, infer whether we need to load the TLS keys etc from whether we have any TLS-enabled listeners. --- changelog.d/4613.feature | 1 + changelog.d/4615.feature | 1 + changelog.d/4615.misc | 1 -
