# ==== Purpose ====
#
# Verify that the correct number of bytes are written by
# mysql_encryption_file_write(...) if both MY_NABP and
# MY_FNABP are not set.
#
# ==== Implementation ====
#
# 1. Start the master with binlog_encryption on.
# 2. Create a table t1 with a TEXT column.
# 3. Execute a trx to insert a big text into the table to make
# binlog cache spill to disk and ensure that the correct
# number of bytes are written by mysql_encryption_file_write(...).
# 4. Verify that an error 'ER_ERROR_ON_WRITE' is reported if there
# is a failure on encrypting binlog cache temporary file.
