From 45be1fe00e93fadab27a8e93e4537f11f6edd5eb Mon Sep 17 00:00:00 2001 From: rinpatch Date: Sat, 1 Aug 2020 17:59:50 +0300 Subject: [PATCH] ConnectionPool: fix gun open errors being returned without an error tuple When gun shuts down due to the host being unreachable, the worker process shuts down with the same shutdown reason since they are linked. Gun doesn't have error tuples in it's shutdown reason though, so we need to handle it in get_conn.
