+# BUG#42829: binlogging enabled for all schemas regardless of
+# binlog-db-db / binlog-ignore-db
+#
+# WHAT
+# ====
+#
+#  We want to test whether filtered events from binlog will cause
+#  raising an error mentioning that statement is unable to be logged or
+#  not, when:
+#
+#   1. isolation level READ-COMMITTED; AND
+#
+#   2. using InnoDB engine; AND
+#
+#   3. using SBL (in which case InnoDB will only allow RBL).
+#
+# HOW
+# ===
+#
+#  The test is implemented as follows:
+#
+#     i) set tx_isolation to read-committed.
+#
+#    ii) create two databases (one filtered other not - using
+#        binlog-do-db)
+#
+#   iii) Create statements that are to be filtered on filtered db
+#
+#       - At this point, before fix, an error would be raised
+#
+#    iv) do the same thing for not the filtered database and check
+#        that events throw an error:
+#
+#      - Error: ER_BINLOG_STMT_MODE_AND_ROW_ENGINE
