# ==== Purpose ====
#
# Check that when the execution of a DROP TABLE command with single table
# fails it should not be written to the binary log. Also test that when the
# execution of DROP TABLE command with multiple tables fails the command
# should be written into the binary log.
#
# ==== Implementation ====
#
# Steps:
# 0 - Create tables named t1, t2, t3
# 1 - Execute DROP TABLE t1,t2,t3 command.
# 2 - Kill the DROP TABLE command while it is trying to drop table 't2'.
# 3 - Verify that tables t2,t3 are present after the DROP command execution
# was interrupted.
# 4 - Check that table 't1' is present in binary log as part of DROP
# command.
#
