#!/bin/bash
# This tests async writing functionality under a set of additional
# conditions (see config for details). This covers non-async cases as
# well. This test was created while actually hunting a bug that was
# very hard to reproduce but severe. While it had different trigger
# conditions, the set of config parameters in this test helped to find
# it quickly. As such the hope is the test will be useful in future again.
#
# NOTE WELL: The rsyslog shutdown condition is hard to get 100% right
# as due to not flushing at transaction end we cannot rely on the output
# file count as we usually do. However, we cannot avoid this as otherwise
# we loose an important trigger condition.
# added 2019-10-23 by Rgerhards
# This file is part of the rsyslog project, released under ASL 2.0
