After fix for bug#21798 JOIN stores the pointer to the buffer for sorting fields. It is used while sorting for grouping and for ordering. If ORDER BY clause has more elements then the GROUP BY clause then a memory overrun occurs. Now the length of the ORDER BY list is always passed to the make_unireg_sortorder() function and it allocates buffer big enough to be used for bigger list. sql/sql_delete.cc: Bug#25172: Not checked buffer size leads to a server crash. Length parameter is initialized to 0 for the make_unireg_sortorder() function. sql/sql_select.cc: Bug#25172: Not checked buffer size leads to a server crash.

UNION over correlated and uncorrelated SELECTS. In such subqueries each uncorrelated SELECT should be considered as uncacheable. Otherwise join_free is called for it and in many cases it causes some problems. mysql-test/r/subselect.result: Added a test case for bug #25219. mysql-test/t/subselect.test: Added a test case for bug #25219. sql/mysql_priv.h: Fixed bug #25219: crash for a query that contains an EXIST subquery with UNION over correlated and uncorrelated SELECTS. In such subqueries each uncorrelated SELECT should be considered as uncacheable. Otherwise join_free is called for it and in many cases it causes some problems. Added a new flag UNCACHEABLE_UNITED for such SELECTs. sql/sql_lex.cc: Fixed bug #25219: crash for a query that contains an EXIST subquery with UNION over correlated and uncorrelated SELECTS.

crashes server Check for null value is reliable only after calling some of the val_xxx() methods. If the val_xxx() method is not called the null_value flag will be set only for certain types of NULL values (like SQL constant NULLs for example). This caused a crash while trying to dereference a NULL pointer that is returned by val_str() for NULL values. Fixed by swapping the order of val_xxx() and null_value check. mysql-test/r/udf.result: Bug #25382: Passing NULL to an UDF called from stored procedures crashes server - test case mysql-test/t/udf.test: Bug #25382: Passing NULL to an UDF called from stored procedures crashes server - test case sql/item_func.cc: Bug #25382: Passing NULL to an UDF called from stored procedures crashes server - reliably check null_value

when they contain the '!' operator. Added an implementation for the method Item_func_not::print. The method encloses any NOT expression into extra parentheses to avoid incorrect stored representations of views that use the '!' operators. Without this change when a view was created that contained the expression !0*5 its stored representation contained not this expression but rather the expression not(0)*5 . The operator '!' is of a higher precedence than '*', while NOT is of a lower precedence than '*'. That's why the expression !0*5 is interpreted as not(0)*5, while the expression not(0)*5 is interpreted as not((0)*5) unless sql_mode is set to HIGH_NOT_PRECEDENCE. Now we translate !0*5 into (not(0))*5. mysql-test/r/sp-code.result: Adjusted results after the fix of bug 25580. mysql-test/r/subselect.result: Adjusted results after the fix of bug 25580. mysql-test/r/view.result: Added a test case for bug #25580. mysql-test/t/view.test: Added a test case for bug #25580. sql/item_cmpfunc.cc: Fixed bug #25580: incorrect stored representations of views in cases when they contain the '!' operator.

The optimizer needs to evaluate whether predicates are better evaluated using an index. IN is one such predicate. To qualify an IN predicate must involve a field of the index on the left and constant arguments on the right. However whether an expression is a constant can be determined only by knowing the preceding tables in the join order. Assuming that only IN predicates with expressions on the right that are constant for the whole query qualify limits the scope of possible optimizations of the IN predicate (more specifically it doesn't allow the "Range checked for each record" optimization for such an IN predicate. Fixed by not pre-determining the optimizability of the IN predicate in the case when all right IN operands are not SQL constant expressions mysql-test/r/func_in.result: BUG#20420: optimizer reports wrong keys on left join with IN - test case mysql-test/t/func_in.test: BUG#20420: optimizer reports wrong keys on left join with IN - test case sql/item_cmpfunc.h: BUG#20420: optimizer reports wrong keys on left join with IN - cannot decide on the optimizability of a function without knowing the tables before it in the join order

in a select list. The objects of the Item_trigger_field class inherited the implementations of the methods copy_or_same, get_tmp_table_item and get_tmp_table_field from the class Item_field while they rather should have used the default implementations defined for the base class Item. It could cause catastrophic problems for triggers that used SELECTs with select list containing trigger fields such as NEW.<table column> under DISTINCT. mysql-test/r/trigger.result: Added a test case for bug #25398. mysql-test/t/trigger.test: Added a test case for bug #25398.

Currently in the ONLY_FULL_GROUP_BY mode no hidden fields are allowed in the select list. To ensure this each expression in the select list is checked to be a constant, an aggregate function or to occur in the GROUP BY list. The last two requirements are wrong and doesn't allow valid expressions like "MAX(b) - MIN(b)" or "a + 1" in a query with grouping by a. The correct check implemented by the patch will ensure that: any field reference in the [sub]expressions of the select list is under an aggregate function or is mentioned as member of the group list or is an outer reference or is part of the select list element that coincide with a grouping element. The Item_field objects now can contain the position of the select list expression which they belong to. The position is saved during the field's Item_field::fix_fields() call. The non_agg_fields list for non-aggregated fields is added to the SELECT_LEX class. The SELECT_LEX::cur_pos_in_select_list now contains the position in the select list of the expression being currently fixed. sql/item.cc: Bug#23417: Too strict checks against GROUP BY in the ONLY_FULL_GROUP_BY mode. The Item_field objects now contain the position of the select list expression which they belong to. The position is saved at the field's Item_field::fix_fields() call. sql/item.h: Bug#23417: Too strict checks against GROUP BY in the ONLY_FULL_GROUP_BY mode. The Item_field objects now can store the position in the select list of the expression to which they are belongs to. sql/mysql_priv.h: Bug#23417: Too strict checks against GROUP BY in the ONLY_FULL_GROUP_BY mode. Added the UNDEF_POS constant. sql/sql_base.cc: Bug#23417: Too strict checks against GROUP BY in the ONLY_FULL_GROUP_BY mode. Now the setup_fields() function maintains the cur_pos_in_select_list variable. sql/sql_lex.cc: Bug#23417: Too strict checks against GROUP BY in the ONLY_FULL_GROUP_BY mode. Set the cur_pos_in_select_list variable and the non_agg_fields list to their initial state. sql/sql_lex.h: Bug#23417: Too strict checks against GROUP BY in the ONLY_FULL_GROUP_BY mode. The non_agg_fields list for non-aggregated fields is added to the SELECT_LEX class. The SELECT_LEX::cur_pos_in_select_list now stores the position in the select list of the expression being currently fixed. sql/sql_select.cc: Bug#23417: Too strict checks against GROUP BY in the ONLY_FULL_GROUP_BY mode. Each select now keeps the list of fields that aren't used under any aggregate function. If an expression from the select list isn't found in the GROUP BY list the setup_group() function additionally checks whether non-aggregated fields occur in that expression. If there at least one such field and it isn't found in the GROUP BY list then an error is thrown. sql/sql_union.cc: Bug#23417: Too strict checks against GROUP BY in the ONLY_FULL_GROUP_BY mode. Clean up of the non_agg_fields list. mysql-test/r/group_by.result: Added a test case for the bug#23417: Too strict checks against GROUP BY in the ONLY_FULL_GROUP_BY mode. mysql-test/t/group_by.test: Added a test case for the bug#23417: Too strict checks against GROUP BY in the ONLY_FULL_GROUP_BY mode.

correctly. The Item_func::print method was used to print the Item_func_encode and the Item_func_decode objects. The last argument to ENCODE and DECODE functions is a plain C string and thus Item_func::print wasn't able to print it. The print() method is added to the Item_func_encode class. It correctly prints the Item_func_encode and the Item_func_decode objects. mysql-test/t/func_str.test: Added a test case for bug#23409: Arguments of the ENCODE() and the > DECODE() functionswere not printed correctly. mysql-test/r/func_str.result: Added a test case for bug#23409: Arguments of the ENCODE() and the DECODE() functions were not printed correctly. sql/item_strfunc.h: Bug#23409: Arguments of the ENCODE() and the DECODE() functions were not printed correctly.

WHERE is present. If a DELETE statement with ORDER BY and LIMIT contains a WHERE clause with conditions that for sure cannot be used for index access (like in WHERE @var:= field) the execution always follows the filesort path. It happens currently even when for the above case there is an index that can be used to speedup sorting by the order by list. Now if a DELETE statement with ORDER BY and LIMIT contains such WHERE clause conditions that cannot be used to build any quick select then the mysql_delete() tries to use an index like there is no WHERE clause at all. mysql-test/t/delete.test: Added a test case for bug#17711: DELETE doesn't use index when ORDER BY, LIMIT and non-restricting WHERE is present. mysql-test/r/delete.result: Added a test case for bug#17711: DELETE doesn't use index when ORDER BY, LIMIT and non-restricting WHERE is present. sql/sql_delete.cc: Bug#17711: DELETE doesn't use index when ORDER BY, LIMIT and non-restricting WHERE is present. Now if a DELETE statement with ORDER BY and LIMIT contains such WHERE clause conditions that cannot be used to build any quick select then the mysql_delete() tries to use an index like there is no WHERE clause at all.

In the method Item_field::fix_fields we try to resolve the name of the field against the names of the aliases that occur in the select list. This is done by a call of the function find_item_in_list. When this function finds several occurrences of the field name it sends an error message to the error queue and returns 0. Yet the code did not take into account that find_item_in_list could return 0 and tried to dereference the returned value. mysql-test/r/order_by.result: Added a test case for bug #25427. mysql-test/t/order_by.test: Added a test case for bug #25427. sql/item.cc: Fixed bug #25427.
