+# ==== Purpose ====
+#
+# Test verifies that when RESET MASTER TO # command is supplied with binlog
+# extension number greater than 2147483647 the command should report
+# appropriate error and binary log should be disabled. It should not result in
+# a crash.
+#
+# ==== Implementation ====
+#
+# Steps:
+#    0 - Verify case with max binary log extension. Max value is '2147483647'
+#    1 - Confirm that SHOW BINARY LOGS displays a binary log with '2147483647'
+#    2 - Verify that events are successfully written into max extension file.
+#    3 - Try to create a binary log with extension greater than max allowed
+#        value '2147483648', verify ER_NO_UNIQUE_LOGFILE error is reported.
+#    4 - Execute CREATE DATABASE db2 statement and verify server dosn't crash.
+#    5 - Execute SHOW BINARY LOG command and verify that it reports
+#        ER_NO_BINARY_LOGGING error.
+#    6 - Restart the server and verify that databse 'db2' exists and it it not
+#        present in the binary log.
