# Bug#21507981: REPLICATION POSITION LOST AFTER CRASH ON MTS CONFIGURED SLAVE
#
# Problem:
# ========
# Enable MTS along with crash-safe replication tables. Make sure that the
# server is busily inserting data with multiple threads in parallel. Shutdown
# mysqld uncleanly (kill -9 or power off server without notice).
#
# Now users are restarting the server with --relay-log-recovery=1 to recover
# the crashed slave.
#
# This results in following error:
# ================================
# 2015-06-24 13:49:03 3895 [ERROR] --relay-log-recovery cannot be executed
# when the slave was stopped with an error or killed in MTS mode; consideri
# using RESET SLAVE or restart the server with --relay-log-recovery = 0
# followed by # START SLAVE UNTIL SQL_AFTER_MTS_GAPS.
#
# i.e relay-log-recovery will not work in MTS mode.
###############################################################################
# Following test demonstrates that when gaps are generated due to MTS crash
# but not due to an error then recovery should be successful with
# --relay-log-recovery=1 option.
#
# In case of Multi source replication all channels will go through the relay
# log recovery process and gaps will be filled.

# Test ensures that after crash recovery the slave is in a consistent state
# and there are no gaps in MTS execution and it is up and running.

#Skip on group replication runs
