a crash when the left operand of the predicate is evaluated to NULL.
It happens when the rows from the inner tables (tables from the subquery)
are accessed by index methods with key values obtained by evaluation of
the left operand of the subquery predicate. When this predicate is
evaluated to NULL an alternative access with full table scan is used
to check whether the result set returned by the subquery is empty or not.
The crash was due to the fact the info about the access methods used for
regular key values was not properly restored after a switch back from the
full scan access method had occurred.
The patch restores this info properly.
The same problem existed for queries with IN subquery predicates if they
were used not at the top level of the queries.

  after a switch back from the alternative full scan access method has 
  occurred. The full scan is used when the left operand of the subquery

database.

If a user has a right to update anything in the current database then the 
access was granted and further checks of access rights for underlying tables
wasn't done correctly. The check is done before a view is opened and thus no
check of access rights for underlying tables can be carried out.
This allows a user to update through a view a table from another database for
which he hasn't enough rights.

Now the mysql_update() and the mysql_test_update() functions are forces
re-checking of access rights after a view is opened.

Bug occurs in INSERT IGNORE ... SELECT ... ON DUPLICATE KEY UPDATE
statements, when SELECT returns duplicated values and UPDATE clause
tries to assign NULL values to NOT NULL fields.
NOTE: By current design MySQL server treats INSERT IGNORE ... ON
DUPLICATE statements as INSERT ... ON DUPLICATE with update of
duplicated records, but MySQL manual lacks this information.
After this fix such behaviour becomes legalized.

The write_record() function was returning error values even within
INSERT IGNORE, because ignore_errors parameter of
the fill_record_n_invoke_before_triggers() function call was
always set to FALSE. FALSE is replaced by info->ignore.

TIMESTAMP field when no value has been provided.

The LOAD DATA sets the current time in the TIMESTAMP field with
CURRENT_TIMESTAMP default value when the field is detected as a null.
But when the LOAD DATA command loads data from a file that doesn't contain
enough data for all fields then the rest of fields are simply set to null
without any check. This leads to no value being inserted to such TIMESTAMP
field.

Now the read_sep_field() and the read_fixed_length() functions set current
time to the TIMESTAMP field with CURRENT_TIMESTAMP default value in all cases
when a NULL value is loaded to the field.

This bug affects multi-row INSERT ... ON DUPLICATE into table
with PRIMARY KEY of AUTO_INCREMENT field and some additional UNIQUE indices.
If the first row in multi-row INSERT contains duplicated values of UNIQUE
indices, then following rows of multi-row INSERT (with either duplicated or
unique key field values) may me applied to _arbitrary_ records of table as
updates.
This bug was introduced in 5.0. Related code was widely rewritten in 5.1, and
5.1 is already free of this problem. 4.1 was not affected too.

When updating the row during INSERT ON DUPLICATE KEY UPDATE, we called
restore_auto_increment(), which set next_insert_id back to 0, but we
forgot to set clear_next_insert_id back to 0.
restore_auto_increment() function has been fixed.

The IN function was comparing DATE/DATETIME values either as ints or as
strings. Both methods have their disadvantages and may lead to a wrong
result.

Now IN function checks whether all of its arguments has the STRING result
types and at least one of them is a DATE/DATETIME item. If so it uses either
an object of the in_datetime class or an object of the cmp_item_datetime
class to perform its work. If the IN() function arguments are rows then
row columns are checked whether the DATE/DATETIME comparator should be used
to compare them.
The in_datetime class is used to find occurence of the item to be checked
in the vector of the constant DATE/DATETIME values. The cmp_item_datetime
class is used to compare items one by one in the DATE/DATETIME context.
Both classes obtain values from items with help of the get_datetime_value()
function and cache the left item if it is a constant one.
