# ==== 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.)
|
|
#
