+# Purpose:
+#   When the mysql.gtid_slave_pos table uses the InnoDB engine, and mysqld
+# starts, it reads the table and begins a transaction. After mysqld reads the
+# value, it should end the transaction and release all associated locks.
+# The bug reported in DBAAS-7828 shows that when autocommit is off, the locks
+# are not released, resulting in indefinite hangs on future attempts to change
+# gtid_slave_pos. This test ensures its fix such that the locks are properly
+# released.

+#
+# Purpose:
+#   When using mariadb-binlog with options for --raw and --stop-never, events
+# from the master's currently active log file should be written to their
+# respective log file specified by --result-file, and shown on-disk. This test
+# ensures that the log files on disk, created by mariadb-binlog, have the most
+# up-to-date events from the master.
+#
+# Methodology:
+#   On the master, rotate to a newly active binlog file and write an event to
+# it. Read the master's binlog using mariadb-binlog with --raw and --stop-never
+# and write the data to an intermediary binlog file (a timeout is used on this
+# command to ensure it exits). Read the local intermediary binlog file to ensure
+# that the master's most recent event exists in the local file.
