# ==== Purpose ====
#
# 1. Verify that the temporary file of binlog cache is encrypted when
#    the binlog cache spills to disk if binlog_encryption is on.
# 2. Verify that 'SET GLOBAL binlog_encryption' takes effect immediately
#    on binlog cache temporary file encryption.
# 3. Verify that binlog cache is reset at commit/rollback time.
#
# ==== 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 tables to make
#    binlog cache spill to disk and ensure that the temporary
#    file of binlog cache is encrypted.
# 4. SET GLOBAL binlog_encryption=OFF
# 5. Execute a trx to ensure binlog cache temporary file encryption
#    is disabled.
# 6. SET GLOBAL binlog_encryption=ON
# 7. Execute a trx to insert a big text into the tables to make
#    binlog cache spill to disk and ensure that the temporary
#    file of binlog cache is encrypted.
# 8. Commit a trx ensure that binlog cache is reset at commit time.
# 9. Rollback a trx ensure that binlog cache is reset at rollback time.
# 10. Verify that there is no difference on the table between
#     master and slave.
