# ==== Purpose ====
#
# Check that when the exectuion 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 ====
# Create a database `db1` on master and ignore this database on the slave side
# using --replicate-ignore-db=db1 --replicate-wild-ignore-table=db1.%. Now
# execute a DROP TABLE command with single table in it and the command should
# fail because of foreign key constraint. Check in the binlog that query should
# not be binlogged. Slave should also be up and running without any errors.
# Execute another DROP TABLE command with multiple tables in the drop list and
# this also fails because of foreign key constraint, check that query gets
# written into the binary log and slave should not fail since query is filtered
# on it.
#

# Bug#21435502: DROP TABLE IF EXISTS MAY BRAKE REPLICATION IF SLAVE HAS
# REPLICATION FILTERS.
