Geometry fields have a result type string and a special subclass to cater for the differences between them and the base class (just like DATE/TIME). When creating temporary tables for results of functions that return results of type GEOMETRY we must construct fields of the derived class instead of the base class. Fixed by creating a GEOMETRY field (Field_geom) instead of a generic BLOB (Field_blob) in temp tables for the results of GIS functions that have GEOMETRY return type (Item_geometry_func). mysql-test/r/gis.result: Bug #27300: test case mysql-test/t/gis.test: Bug #27300: test case sql/item.cc: Bug #27300: Create a GEOMETRY field (Field_geom) instead of a generic BLOB (Field_blob) in temp tables for the results of GIS functions (Item_geometry_func). sql/sql_select.cc: Bug #27300: Create a GEOMETRY field (Field_geom) instead of a generic BLOB (Field_blob) in temp tables for the results of GIS functions (Item_geometry_func).

If a set function with a outer reference s(outer_ref) cannot be aggregated the outer query against which the reference has been resolved then MySQL interpretes s(outer_ref) in the same way as it would interpret s(const). Hovever the standard requires throwing an error in this situation. Added some code to support this requirement in ansi mode. Corrected another minor bug in Item_sum::check_sum_func. mysql-test/r/subselect.result: Added a test case for bug #27348. mysql-test/t/subselect.test: Added a test case for bug #27348. sql/item_sum.cc: Fixed bug #27348.

to 0 causes wrong (large) length to be read from the row in _mi_calc_blob_length() when storing NULL values in (e.g) POINT columns. This large length is then used to allocate a block of memory that (on some OSes) causes trouble. Fixed by calling the base class's Field_blob::reset() from Field_geom::reset() that is called when storing a NULL value into the column. mysql-test/r/gis.result: Bug #27164: test case mysql-test/t/gis.test: Bug #27164: test case sql/field.h: Bug #27164: not reseting the data pointer to 0 causes wrong (large) length to be read from the row in _mi_calc_blob_length() when storing NULL values in (e.g) POINT columns.

from func_group.test after the patch for bug #27229 had been applied. The memory corruption happened because in some rare cases the function count_field_types underestimated the number of elements in in the array param->items_to_copy. sql/item_sum.cc: The return value of the Item_sum::update_used_tables method should not depend on the place of aggregation of the set function for which the Item_sum object has been created. sql/sql_select.cc: This is a fix for the memory corruption occurred in one of test cases from func_group.test after the patch for bug #27229 had been applied. The memory corruption happened because in some rare cases the function count_field_types underestimated the number of elements in in the array param->items_to_copy. Currently it's not guaranteed that after JOIN::prepare() the used_tables attribute is calculated for all items. For example for the expression SUM(outer_ref)+1 used_tables() must return OUTER_REF_TABLE_BIT. Yet by the moment when the used_tables attribute is calculated in JOIN::prepare SUM(outer_ref) has not been substituted for Item_aggregate_ref yet. By this reason additional calls of the method update_used_tables are needed for some items passed as parameters to the function create_tmp_table.

context was used as an argument of GROUP_CONCAT. Ensured correct setting of the depended_from field in references generated for set functions aggregated in outer selects. A wrong value of this field resulted in wrong maps returned by used_tables() for these references. Made sure that a temporary table field is added for any set function aggregated in outer context when creation of a temporary table is needed to execute the inner subquery. mysql-test/r/subselect.result: Added a test case for bug #27229. mysql-test/t/subselect.test: Added a test case for bug #27229. sql/item.cc: Fixed bug #27229: crash when a set function aggregated in outer context was used as an argument of GROUP_CONCAT. Ensured correct setting of the depended_from field in references generated for set functions aggregated in outer selects. sql/item_sum.cc: Fixed bug #27229: crash when a set function aggregated in outer context was used as an argument of GROUP_CONCAT. Added the field aggr_sel to the objects of the class Item_sum. In any Item_sum object created for a set function this field has to contain a pointer to the select where the set function is aggregated. sql/item_sum.h: Fixed bug #27229: crash when a set function aggregated in outer context was used as an argument of GROUP_CONCAT. Added the field aggr_sel to the objects of the class Item_sum. In any Item_sum object created for a set function this field has to contain a pointer to the select where the set function is aggregated. Added a method that says whether a set function is aggregated in outer context and, if so, returns the aggregating select. Removed the field nest_level_tables_count introduced by the patch for bug 24484 as aggr_sel->join->tables contains the sane number. sql/sql_base.cc: Fixed bug #27229: crash when a set function aggregated in outer context was used as an argument of GROUP_CONCAT. Added the field aggr_sel to the objects of the class Item_sum. Removed changes introduced by the patch for bug 24484 as the field leaf_count of the THD class is not used anymore. sql/sql_class.h: Fixed bug #27229: crash when a set function aggregated in outer context was used as an argument of GROUP_CONCAT.

another user. When the DEFINER clause isn't specified in the ALTER statement then it's loaded from the view definition. If the definer differs from the current user then the error is thrown because only a super-user can set other users as a definers. Now if the DEFINER clause is omitted in the ALTER VIEW statement then the definer from the original view is used without check. mysql-test/t/view_grant.test: Added a test case for the bug#27006: The SUPER privilege is wrongly required to alter a view created by another user. mysql-test/r/view_grant.result: Added a test case for the bug#27006: The SUPER privilege is wrongly required to alter a view created by another user. sql/sql_view.cc: Bug#26813: The SUPER privilege is wrongly required to alter a view created by another user.

in index search MySQL was not explicitly suppressing warnings. And if the context happens to enable warnings (e.g. INSERT .. SELECT) the warnings resulting from converting the data the key is compared to are reported to the client. Fixed by suppressing warnings when converting the data to the same type as the key parts. mysql-test/r/insert_select.result: Bug #26207: test case mysql-test/t/insert_select.test: Bug #26207: test case sql/sql_select.h: Bug #26207: supress warnings when converting data of the same type to key buffer format.

Patch appled after doing a pull from the team tree. Additional tests had to be fixed mysql-test/r/union.result: Bug 24791 The tests for temporary tables have been fixed. Since the call to display_length(Item) was removed from the constructor for Item_type_holder, items in temporary tables keep the original values of the items, rather than the magic numbers supplied by display_length.

The problem in this bug is when we create temporary tables. When temporary tables are created for unions, there is some inferrence being carried out regarding the type of the column. Whenever this column type is inferred to be REAL (i.e. FLOAT or DOUBLE), MySQL will always try to maintain exact precision, and if that is not possible (there are hardware limits, since FLOAT and DOUBLE are stored as approximate values) will switch to using approximate values. The problem here is that at this point the information about number of significant digits is not available. Furthermore, the number of significant digits should be increased for the AVG function, however, this was not properly handled. There are 4 parts to the problem: #1: DOUBLE and FLOAT fields don't display their proper display lengths in max_display_length(). This is hard-coded as 53 for DOUBLE and 24 for FLOAT. Now changed to instead return the field_length. #2: Type holders for temporary tables do not preserve the max_length of the Item's from which they are created, and is instead reverted to the 53 and 24 from above. This causes *all* fields to get non-fixed significant digits. #3: AVG function does not update max_length (display length) when updating number of decimals. #4: The function that switches to non-fixed number of significant digits should use DBL_DIG + 2 or FLT_DIG + 2 as cut-off values (Since fixed precision does not use the 'e' notation) Of these points, #1 is the controversial one, but this change is preferred and has been cleared with Monty. The function causes quite a few unit tests to blow up and they had to b changed, but each one is annotated and motivated. We frequently see the magical 53 and 24 give way to more relevant numbers. mysql-test/r/create.result: bug#24791 changed test result With the changes made for FLOAT and DOUBLE, the original display lengths are now preserved. mysql-test/r/temp_table.result: bug#24791 changed test resullt Test case added mysql-test/r/type_float.result: bug#24791 changed test result delta 1: field was originally declared as DOUBLE with no display length, so the hardware maximum is chosen rather than 53. delta 2: fields exceed the maximum precision and thus switch to non-fixed significant digits delta 3: Same as above, number of decmals and significant digits was not specified when t3 was created. mysql-test/t/temp_table.test: bug#24791 Test case sql/field.h: bug#24791 The method max_display_length is reimplemented as uint32 max_display_length() { return field_length; } in Field_double and Field_float. Since all subclasses of Field_real now have the same implementation of this method, the implementation has been moved up the hierarchy to Field_real. sql/item.cc: bug#24791 We switch to a non-fixed number of significant digits (by setting decimals=NOT_FIXED_DECIMAL) if the calculated display length is greater than the display length of a value with the maximum precision. These values differ for double and float, obviously. sql/item_sum.cc: bug#24791 We must increase the display length accordinly whenever we change number of decimal places.

fix for cast( AS DATETIME)+0 in 5.0 and above versions. val_real now works using val_decimal for DATETIME Items Superfluous val_real() methods deleted sql/item_timefunc.h: val_real() for datetime functions implemented as { return val_real_from_decimal(); } It's not a fastest possible way, but code is simple and less error-prone, what i belive is more important here as this part works unfrequently.
