# ==== Requirements ====
#
# mysqlbinlog should decode rows containing JSON values correctly:
# R1. Correct JSON should be written (not the raw binary format)
# R2. JSON bigger than 65536 bytes should work
#
# ==== Implementation ====
#
# Execute an INSERT, an UPDATE, and a DELETE.
# Ensure that at least one of them has a value greater than 65536 bytes
# Check the output.
#
# Use sed to filter the huge strings from the output (not mysqltest's
# replace, because it is very slow on long strings.)
#
