+# needed to ensure that state information was not updated when
+# executing analyze table for a locked table.  The analyze table had
+# to be within locks and check table had to be after unlocking since
+# then it brings the wrong state from disk rather than from the

+# Bug#20691: DATETIME col (NOT NULL, NO DEFAULT) may insert garbage when specifying DEFAULT
+#
+# From the docs:
+#  If the column can take NULL as a value, the column is defined with an
+#  explicit DEFAULT NULL clause. This is the same as before 5.0.2.
+#
+#  If the column cannot take NULL as the value, MySQL defines the column with
+#  no explicit DEFAULT clause. For data entry, if an INSERT or REPLACE
+#  statement includes no value for the column, MySQL handles the column
+#  according to the SQL mode in effect at the time:
+#
+#    * If strict SQL mode is not enabled, MySQL sets the column to the
+#      implicit default value for the column data type.
+#
+#    * If strict mode is enabled, an error occurs for transactional tables and
+#      the statement is rolled back. For non-transactional tables, an error
+#      occurs, but if this happens for the second or subsequent row of a
+#      multiple-row statement, the preceding rows will have been inserted.

+# 1. You have more time and want to get as much value from you test case as
+#    possible. Please try to make the following decisions:
+#
+#    Will the execution or result of the sub test case depend on the
+#    properties of a storage engine ?
+#
+#      NO   --> alter t/ps_1general.test (Example: Command with syntax error)
+#               If you need a table, please try to use
+#               t1               - very simple table
+#               t9 - table with nearly all available column types
+#               whenever possible.
+#
+#               The structure and the content of these tables can be found in
+#               include/ps_create.inc  CREATE TABLE ...
+#               include/ps_renew.inc   DELETE all rows and INSERT some rows
+#
+#               Both tables are managed by the same storage engine.
+#               The type of the storage engine is stored in the variable 
+#               '$type' .  In ps_1general.test $type is set to 'MYISAM'.
+#    
+#               Please feel free to source ps_create.inc or ps_renew.inc
+#               whenever you think it helps. But please restore the original
+#               state of these tables after your tests, because the following
+#               statements may depend on it.
+#
+#      YES
+#       |
+#       |
+#    Is it possible to apply the sub test case to all table types ?
+#      YES  --> alter include/ps_query.inc   (for SELECTs)
+#                     include/ps_modify.inc  (for INSERT/UPDATE/DELETE)
+#                     include/ps_modify1.inc (also for INSERT/UPDATE/DELETE,
+#                                but t/ps_5merge.test will not source that file)
+#               Please try to find an appropriate place within the file.
+#               It would be nice if we have some systematics in the
+#               order of the sub test cases (if possible).
+#
+#               Please be aware, that
+#                  include: ps_query.inc, ps_modify.inc, ps_modify1.inc
+#               will be sourced by several test case files stored within the 
+#               subdirectory 't'. So every change here will affect several test
+#               cases.
+#
+#      NO
+#       |
+#       |
+#    Append the sub test case to the appropriate 
+#                  ps_<number><table type>.test  .
+#
+# 2. The current structure of the PS tests
+#
+#    t/ps_1general.test     Check of basic PS features, SHOW commands and DDL
+#                           The tests should not depend on the table type.
+#
+#    t/ps_2myisam           Check of PS on tables of type MYISAM .
+#    t/ps_3innodb           Check of PS on tables of type InnoDB .
+#    ...
+#    t/ps_6bdb              Check of PS on tables of type BDB .
+#         All storage engine related tests use the variable $type to hold the
+#         name of the storage engine.        
+#
+#    include/ps_query.inc   test cases with SELECT/... 
+#                           These test cases should not modify the content or
+#                           the structure (DROP/ALTER..) of the tables
+#                           't1' and 't9'.
+#    include/ps_modify.inc  test cases with INSERT/UPDATE/... 
+#                           These test cases should not modify the structure 
+#                           (DROP/ALTER..) of the tables
+#                           't1' and 't9'.
+#         These two test sequences will be applied to all table types .
+#
+#    include/ps_modify1.inc test cases with INSERT/UPDATE/...
+#         This test sequences will be applied to all table types 
+#         except MERGE tables.
+#
+#    include/ps_create.inc  DROP and CREATE of the tables 
+#                             't1' and 't9' .
+#    include/ps_renew.inc   DELETE all rows and INSERT some rows, that means
+#                           recreate the original content of these tables.
+#         Please do not alter the commands concerning these two tables.
+#
+#  Please feel free and encouraged to exploit the current code sharing
+#  mechanism of the 'ps_<number><table type>' test cases. It is an convenient

+# will be converted internally to real (double) value and it is not

+ * Record buffer size:
+ * -------------------
+ * The size of the record buffer used to hold the row
+ * in memory. This buffer size does not include the BLOB data.
+ * About 8 bytes (a pointer and a size) is reserved for each BLOB
+ * in this buffer.
+ *
+ * The buffer size includes a number of "NULL" bytes followed by
+ * the data area. The NULL bytes contain 1 bit for every column,
+ * to indicate of the columns is NULL or not.
+ *
+ * The size of the buffer is 4/8-byte aligned, so it may be padded
+ * at the end.
+ *
+ * Fixed length rec. len.:
+ * -----------------------
+ * If the record does not include any BLOBs then this is the size of the
+ * fixed length record. The size if the data in the data handle record
+ * need never be bigger then this length, if the record does not
+ * contain BLOBs. So this should be the maximum size set for
+ * AVG_ROW_LENGTH in this case.
+ *
+ * Handle data record size:
+ * ------------------------
+ * This is the size of the handle data record. It is the data size
+ * plus the "max header size".
+ *
+ * Min/max header size:
+ * The min and max header size of the header in the data handle file.
+ * The larger header is used if a record has an extended data (data log
+ * file) component.
+ *
+ * Min/avg/max record size:
+ * ------------------------
+ * These are variable length records sizes. That is, the size of records
+ * when stored in the variable length format. Variable length records
+ * do not have fixed fields sizes, instead the fields are packed one
+ * after the other, prefixed by a number of size indicator bytes.
+ *
+ * The average is an estimate of the average record size. This estimate
+ * is used if no AVG_ROW_LENGTH is specifically given.
+ *
+ * If the average estimate is withing 20% of the maximum size of the record,
+ * then the record will be handled as a fixed length record.
+ *
+ * Avg row len set for tab:
+ * ------------------------
+ * This is the value set using AVG_ROW_LENGTH when the table is declared.
+ *
+ * Rows fixed length:
+ * ------------------
+ * YES if the records of this table are handled as a fixed length records.
+ * In this case the table records will never have an extended record
+ * component.
+ *
+ * The size of the data area in the handle data record is set to the
+ * size of the MySQL data record ("Fixed length rec. len.").
+ *
+ * It also means that the record format used is identical to the MySQL
+ * record format.
+ *
+ * If the records are not fixed, then the variable length record format
+ * is used. Records size are then in the range specified by
+ * "Min/avg/max record size".
+ *
+ * Maximum fixed size:
+ * -------------------
+ * This is the maximum size of a data log record.
+ *
+ * Minimum variable size:
+ * ------------------------
+ * Records below this size are handled as a fixed length record size, unless
+ * the AVG_ROW_LENGTH is specifically set.
