differences in tables
Certain merge tables were wrongly reported as having incorrect definition:
- Some fields that are 1 byte long (e.g. TINYINT, CHAR(1)), might
be internally casted (in certain cases) to a different type on a
storage engine layer. (affects 4.1 and up)
- If tables in a merge (and a MERGE table itself) had short VARCHAR column (less
than 4 bytes) and at least one (but not all) tables were ALTER'ed (even to an
identical table: ALTER TABLE xxx ENGINE=yyy), table definitions went ouf of
sync. (affects 4.1 only)
This is fixed by relaxing a check for underlying conformance and setting
field type to FIELD_TYPE_STRING in case varchar is shorter than 4
when a table is created.

sql/ha_myisam.cc:
Relaxed some checks performed by check_definition():
As comparing of fulltext keys (and key segments) is not yet implemented,
only return an error in case one of keys is fulltext and other is not.
Otherwise, if both keys are fulltext, accept them as is.
As comparing of spatial keys (and key segments) is not yet implemented,
only return an error in case one of keys is spatial and other is not.
Otherwise, if both keys are spatial, accept them as is.
A workaround to handle situation when field is casted from FIELD_SKIP_ZERO
to FIELD_NORMAL. This could happen only in case field length is 1 and row
format is fixed.
sql/sql_parse.cc:
When a table that has varchar field shorter than 4 is created, field type is
set to FIELD_TYPE_VAR_STRING. Later, when a table is modified using alter
table, field type is changed to FIELD_TYPE_STRING (see Field_string::type).
That means HA_OPTION_PACK_RECORD flag might be lost and thus null_bit might
be shifted by alter table, in other words alter table doesn't create 100%
equal table definition.
This is usually not a problem, since when a table is created/altered,
definition on a storage engine layer is based on one that is passed from
sql layer. But it is a problem for merge engine - null_bit is shifted when
a table (merge or underlying) is altered.
Set field type to FIELD_TYPE_STRING in case FIELD_TYPE_VAR_STRING is shorter
than 4 when a table is created as it is done in Field::type.
when the column is to be read from a derived table column which
was specified as a concatenation of string literals.
The bug happened because the Item_string::append did not adjust the
value of Item_string::max_length. As a result of it the temporary
table column defined to store the concatenation of literals was
not wide enough to hold the whole value.

after single-row table substitution could lead to a wrong result set.

This not true for fields becoming constant after row substitutions

When the SUBSTRING() function was used over a LONGTEXT field the max_length of
the SUBSTRING() result was wrongly calculated and set to 0. As the max_length
parameter is used while tmp field creation it limits the length of the result
field and leads to printing an empty string instead of the correct result.
Now the Item_func_substr::fix_length_and_dec() function correctly calculates
the max_length parameter.

When rand() is called multiple times inside a stored procedure, the server does
not binlog the correct random seed values.
This patch corrects the problem by resetting rand_used= 0 in
THD::cleanup_after_query() allowing the system to save the random seeds if needed
for each command in a stored procedure body.
However, rand_used is not reset if executing in a stored function or trigger
because these operations are binlogged by call and thus only the calling statement
need detect the call to rand() made by its substatements. These substatements must
not set rand_used to 0 because it would remove the detection of rand() by the
calling statement.

incorrect key file for table
In certain cases it could happen that deleting a row could
corrupt an RTREE index.
According to Guttman's algorithm, page underflow is handled
by storing the page in a list for later re-insertion. The
keys from the stored pages have to be inserted into the
remaining pages of the same level of the tree. Hence the
level number is stored in the re-insertion list together
with the page.
In the MySQL RTree implementation the level counts from zero
at the root page, increasing numbers for levels down the tree.
If during re-insertion of the keys the tree height grows, all
level numbers become invalid. The remaining keys will be
inserted at the wrong level.
The fix is to increment the level numbers stored in the
reinsert list after a split of the root block during reinsertion.
myisam/rt_index.c:
Bug#25673 - spatial index corruption, error 126

For built-in functions like sqrt() function names are hard-coded and can be

DATE/DATETIME values are out of the currently supported
4 basic value types (INT,STRING,REAL and DECIMAL).
So expressions (not fields) of compile type DATE/DATETIME are
generally considered as STRING values. This is not so
when they are compared : then they are compared as
INTEGER values.
But the rule for comparison as INTEGERS must be checked
explicitly each time when a comparison is to be performed.
filesort is one such place. However there the check was
not done and hence the expressions (not fields) of type
DATE/DATETIME were sorted by their string representation.
Fixed to compare them as INTEGER values for filesort.
