# 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.
