# Bug#21205695 DROP TABLE MAY CAUSE SLAVES TO BREAK
#
# Problem:
# ========
# 1) Drop table queries are re-generated by server
# before writing the events(queries) into binlog
# for various reasons. If table name/db name contains
# a non regular characters (like latin characters),
# the generated query is wrong. Hence it breaks the
# replication.
# 2) In the edge case, when table name contains
# 64 latin characters (latin takes 2 bytes), server is
# throwing an assert (M_TBLLEN < 128)
#
# 3) In the edge case, when db name contains 64 latin
# characters, binlog contents are interpreted wrongly
# which is leading to replication issues.
