From ec2b8da9839bd5e63299595642d0b4c6b982e119 Mon Sep 17 00:00:00 2001 From: Fabio Manganiello Date: Thu, 17 Aug 2023 01:49:41 +0200 Subject: [PATCH] Ignore Redis errors when a backend sends an unregister notify event. When that happens, it's most likely that the application is already stopping and the Redis service has already been terminated. --- platypush/backend/__init__.py | 27 +++++++++++++++++---------- 1 file changed, 17 insertions(+), 10 deletions(-) diff --git a/platypush/backend/__init__.py b/platypush/backend/__init__.py index c8b0ea65d..4835e1543 100644 --- a/platypush/backend/__init__.py +++ b/platypush/backend/__init__.py @@ -441,6 +441,8 @@ class Backend(Thread, EventGenerator, ExtensionWithManifest): """ Unregister the Zeroconf service configuration if available.
