+# Bug#56632: ALTER TABLE implicitly changes ROW_FORMAT to COMPRESSED
+# http://bugs.mysql.com/56632
+#
+# Innodb automatically uses compressed mode when the KEY_BLOCK_SIZE
+# parameter is used, except if the ROW_FORMAT is also specified, in
+# which case the KEY_BLOCK_SIZE is ignored and a warning is shown.
+# But Innodb was getting confused when neither of those parameters
+# was used on the ALTER statement after they were both used on the
+# CREATE.
+#
+# This will test the results of all 4 combinations of these two
+# parameters of the CREATE and ALTER.
+#
+#    Tests 1-5 use INNODB_STRICT_MODE=1 which returns an error
+#    if there is anything wrong with the statement.
+#
+# 1) CREATE with ROW_FORMAT=COMPACT & KEY_BLOCK_SIZE=1, ALTER with neither.
+#    Result; CREATE; fails with error ER_CANT_CREATE_TABLE
+# 2) CREATE with ROW_FORMAT=COMPACT, ALTER with KEY_BLOCK_SIZE=1
+#    Result; CREATE succeeds,
+#            ALTER quietly converts ROW_FORMAT to compressed.
+# 3) CREATE with KEY_BLOCK_SIZE=1, ALTER with ROW_FORMAT=COMPACT
+#    Result; CREATE quietly converts ROW_FORMAT to compressed,
+#            ALTER fails with error ER_CANT_CREATE_TABLE.
+# 4) CREATE with neither, ALTER with ROW_FORMAT=COMPACT & KEY_BLOCK_SIZE=1
+#    Result; CREATE succeeds,
+#            ALTER; fails with error ER_CANT_CREATE_TABLE
+# 5) CREATE with KEY_BLOCK_SIZE=3 (invalid), ALTER with neither.
+#    Result; CREATE; fails with error ER_CANT_CREATE_TABLE
+#
+#    Tests 6-11 use INNODB_STRICT_MODE=0 which automatically makes
+#    adjustments if the prameters are incompatible.
+#
+# 6) CREATE with ROW_FORMAT=COMPACT & KEY_BLOCK_SIZE=1, ALTER with neither.
+#    Result; CREATE succeeds, warns that KEY_BLOCK_SIZE is ignored.
+#            ALTER succeeds, no warnings.
+# 7) CREATE with ROW_FORMAT=COMPACT, ALTER with KEY_BLOCK_SIZE=1
+#    Result; CREATE succeeds,
+#            ALTER quietly converts ROW_FORMAT to compressed.
+# 8) CREATE with KEY_BLOCK_SIZE=1, ALTER with ROW_FORMAT=COMPACT
+#    Result; CREATE quietly converts ROW_FORMAT to compressed,
+#            ALTER succeeds, warns that KEY_BLOCK_SIZE is ignored.
+# 9) CREATE with neither, ALTER with ROW_FORMAT=COMPACT & KEY_BLOCK_SIZE=1
+#    Result; CREATE succeeds,
+#            ALTER succeeds, warns that KEY_BLOCK_SIZE is ignored.
