#REGTEST_TYPE=devel

# This reg-test checks that the connection and SSL sample fetches related to
# errors are functioning properly. It also tests the proper behaviour of the
# default HTTPS log format and of the error-log-format  option which allows to
# define a specific log format used only in case of connection error (otherwise
# a line following the configured log-format is output).
#
# It works by sending request through three different paths, one using a custom
# log-format line that contains the connection error and SSL handshake error
# sample fetches, one using the default HTTPS log-format and one using the
# legacy error log format.
#
# The output log lines are caught by syslog blocks (one for each path) and
# compared to an expected format.
# Since the syslog is not by design synchronized with the Varnish clients and
# servers, synchronization is achieved through barriers, which ensure that
# syslog messages arrive in the right order.
#
# In order to ensure that the log line raised in case of connection error if an
# error-log-format is defined still follows the log-separate-error option, the
# log lines raised by the https_fmt_lst listener will be sent to two separate
# syslog servers.
