# ==== Purpose ====
#
# Bug#18091217  Slave I/O thread won't attempt auto reconnect to the master / error-code 1159
#
# The slave receiver thread stops due to the 'ER_NET_READ_INTERRUPTED'
# or 'ER_NET_WRITE_INTERRUPTED' error is encountered while getting
# timestamp, server id from master, setting @master_heartbeat_period
# and so on.
#
# To fix the problem, we fix to handle the 'ER_NET_READ_INTERRUPTED'
# and 'ER_NET_WRITE_INTERRUPTED' errors as transient network errors.
# Then the slave receiver thread attempts to automatically reconnect
# to the master on these errors.
#
# Steps to reproduce:
#  1) Log on slave, stop slave threads.
#  2) Active injected error during getting server id from master
#  3) Start slave theads to verify that their is no error happened.
#

--source include/master-slave.inc
# The error injection works only with debug facilities.
--source include/have_debug.inc
--source include/have_debug_sync.inc
# The test is not supposed to have any binlog affairs.
# Hence it's enough to run only with one binlog format
