+# Test evaluation of replication table filter rules
+#
+# ==== Purpose ====
+#
+# Test if replication table filter rules are properly evaluated when
+# some of the tables referenced by the multiple-table update do not
+# exist on slave.
+#
+# ==== Method ====
+#
+# Master creates tables t1, t2, t3, t4, t5, t6, t7, t8, t9 and the
+# slave is started with the following replication table filter rules:
+#
+# --replicate-do-table=t1
+# --replicate-do-table=t2
+# --replicate-do-table=t3
+#
+# and
+#
+# --replicate-ignore-table=t4
+# --replicate-ignore-table=t5
+# --replicate-ignore-table=t6
+#
+# So the slave only replicate changes to tables t1, t2 and t3 and only
+# these tables exist on slave.
+#
+# From now on, tables t1, t2, and t3 are referenced as do tables,
+# tables t4, t5, t6 are referenced as ignore tables, and tables t7,
+# t8, t9 are referenced as other tables.
+#
+# All multi-table update tests reference tables that are not do
+# tables, which do not exist on slave. And the following situations
+# of multi-table update will be tested:
+#
+# 1. Do tables are not referenced at all
+# 2. Do tables are not referenced for update
+# 3. Ignore tables are referenced for update before do tables
+# 4. Only do tables are referenced for update
+# 5. Do tables and other tables are referenced for update
+# 6. Do tables are referenced for update before ignore tables
+#
+# For 1, 2 and 3, the statement should be ignored by slave, for 4, 5
+# and 6 the statement should be accepted by slave and cause an error
+# because of non-exist tables.
