# ==== Purpose ====
#
# Test verifies that when an admin command execution is interrupted by KILL
# command it should stop its execution. The admin command in binary log should
# contain only the list of tables which have successfully executed admin
# command prior to kill.
#
# ==== Implementation ====
#
# Steps:
# 0 - Create two table t1,t2.
# 1 - Execute OPTIMIZE TABLE t1,t2 command.
# 2 - Using debug sync mechanism kill OPTIMIZE TABLE command at a stage
# where it has not optimized any table.
# 3 - Check that OPTIMIZE TABLE command is not written to binary log.
# 4 - Using debug sync mechanism hold the execution of OPTIMIZE TABLE after
# t1 table optimization. Now kill the OPTIMIZE TABLE command.
# 5 - Observe the binlog output, the OPTIMIZE TABLE command should display `t1,t2`.
# 6 - Please note that, we binlog the entire query even if at least one
# table is modified as admin commands are safe to replicate and they will
# not make the slave to diverge.
#
# ==== References ====
#
# MDEV-22530: Aborting OPTIMIZE TABLE still logs in binary log and replicates to the Slave server.
