* Split item->flags into base_flags and with_flagsMonty2021-05-191-8/+4
| | | | | | | | | | | | | | This was done to simplify copying of with_* flags Other things: - Changed Flags to C++ enums, which enables gdb to print out bit values for the flags. This also enables compiler errors if one tries to manipulate a non existing bit in a variable. - Added set_maybe_null() as a shortcut as setting the MAYBE_NULL flags was used in a LOT of places. - Renamed PARAM flag to SP_VAR to ensure it's not confused with persistent statement parameters.
* Change bitfields in Item to an uint16Michael Widenius2021-05-191-9/+10
| | | | | | | | The reason for the change is that neither clang or gcc can do efficient code when several bit fields are change at the same time or when copying one or more bits between identical bit fields. Updated bits explicitely with & and | is MUCH more efficient than what current compilers can do.
* Revert MDEV-14517 Cleanup for Item::with_subselectMichael Widenius2021-05-191-1/+1
| | | | | | | | | | | | | | | Added back variable 'with_subquery' to Item class as a bit field. This made the code shorter, faster (removed some virtual methods, less code to create an initialized item etc) and made many Item's 7 bytes smaller. This is the last set of my patches the decreases the size of Item. Some examples from gdb: sizeof(Item): 144 -> 120 sizeof(Item_func) 208 -> 184 sizeof(Item_sum_max) 368 -> 344
* Revert MDEV-16592 "Change Item::with_sum_func to a virtual method"Michael Widenius2021-05-191-1/+1
| | | | | | | | | | | Added back variable 'with_sum_func' to Item class as a bit field. This made the code shorter, faster (removed some virtual methods, less code to create an initialized item etc) and made many Item's 7 bytes smaller. The code is also easier to understand as 'with_sum_func' is threated as any other Item variable when creating or copying items.

| | | * MDEV-17177 Crash in Item_func_in::cleanup() for SELECT executed viaIgor Babaev2020-03-201-4/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | prepared statement The method Item_func_in::build_clone() that builds a clone item for an Item_func_in item first calls a generic method Item_func::build_item() that builds the the clones for the arguments of the Item_func_in item to be cloned, creates a copy of the Item_func_in object and attaches the clones for the arguments to this copy. Then the method Item_func_in::build_clone() makes the copy fully independent on the copied object in order to guarantee a proper destruction of the clone. The fact is the copy of the Item_func_in object is registered as any other item object and should be destructed as any other item object. If the method Item_func::build_item fails to build a clone of an argument then it returns 0. In this case no copy of the Item_func_in object should be created. Otherwise the finalizing actions for this copy would not be performed and the copy would remain in a state that would prevent its proper destruction. The code of Item_func_in::build_clone() before this patch created the copy of the Item_func_in object before cloning the argument items. If this cloning failed the server crashed when trying to destruct the copy item. The code of Item_row::build_clone() was changed similarly to the code of Item_func::build_clone though this code could not cause any problems.

Additionally, fix_fields() could be called multiple times for SP variables, because they are all fixed at a early stage in append_for_log(). Solution: 1. Adding a few helper methods - fix_fields_if_needed() - fix_fields_if_needed_for_scalar() - fix_fields_if_needed_for_bool() - fix_fields_if_needed_for_order_by() and using it in many cases instead of fix_fields() where the "fixed" status is not definitely known to be "false". 2. Adding DBUG_ASSERT(!fixed) into Item_splocal*::fix_fields() to catch double execution. 3. Adding tests. As a good side effect, the patch removes a lot of duplicate code (~60 lines): if (!item->fixed && item->fix_fields(..) && item->check_cols(1)) return true;

| | | | * MDEV-15035 Wrong results when calling a stored procedureIgor Babaev2018-04-251-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | multiple times with different arguments. If the ON expression of an outer join is an OR formula with one of the disjunct being a constant formula then the expression cannot be null-rejected if the constant formula is true. Otherwise it can be null-rejected and if so the outer join can be converted into inner join. This optimization was added in the patch for mdev-4817. Yet the code had a defect: if the query was used in a stored procedure with parameters and the constant item contained some of them then the value of this constant item depended on the values of the parameters. With some parameters it may be true, for others not. The validity of conversion to inner join is checked only once and it happens only for the first call of procedure. So if the parameters in the first call allowed the conversion it was done and next calls used the transformed query though there could be calls whose parameters made the conversion invalid. Fixed by cheking whether the constant disjunct in the ON expression originally contained an SP parameter. If so the expression is not considered as null-rejected. For this check a new item's attribute was intruduced: Item::with_param. It is calculated for each item by fix fields() functions. Also moved the call of optimize_constant_subqueries() in JOIN::optimize after the call of simplify_joins(). The reason for this is that after the optimization introduced by the patch for mdev-4817 simplify_joins() can use the results of execution of non-expensive constant subqueries and this is not valid.

The patch mainly contains the code ported from mysql-5.6 and created for two essential architectural changes: 1. WL#5558: Resolve ORDER BY execution method at the optimization stage 2. WL#6071: Inline tmp tables into the nested loops algorithm The first task was implemented for mysql-5.6 by Ole John Aske. It allows to make all decisions on ORDER BY operation at the optimization stage. The second task implemented for mysql-5.6 by Evgeny Potemkin adds JOIN_TAB nodes for post-join operations that require temporary tables. It allows to execute these operations within the nested loops algorithm that used to be used before this task only for join queries. Besides these task moves all planning on the execution of these operations from the execution phase to the optimization phase. Some other re-factoring changes of mysql-5.6 were pulled in, mainly because it was easier to pull them in than roll them back. In particular all changes concerning Ref_ptr_array were incorporated. The port required some changes in the MariaDB code that concerned the functionality of EXPLAIN and ANALYZE. This was done mainly by Sergey Petrunia.

GROUP BY did wrongly show 'Using filesort' in some cases involving "Using index for group-by" a) was fixed by: - Changed last argument to Item::split_sum_func2() from bool to int to allow more flags - Added flag argument to Item::split_sum_func() to allow on to specify if the item was in the SELECT part - Mark all split_sum_func() calls from SELECT with SPLIT_SUM_SELECT - Changed split_sum_func2() to do nothing if called with an argument that is not a sum function and doesn't include sum functions, if we are not an argument to SELECT. This ensures that in a case like select a*sum(b) as f1 from t1 where a=1 group by c having f1 <= 10; That 'a' in the SELECT part is stored as a reference in the temporary table togeher with sum(b) while the 'a' in having isn't (not needed as 'a' is already a reference to a column in the result) b) was fixed by: - Added an extra remove_const() pass for GROUP BY arguments before make_join_statistics() in case of one table SELECT. This allowes get_best_group_min_max() to optimize things better. c) was fixed by: - Added test for group by optimization in JOIN::exec_inner for select->quick->get_type() == QUICK_SELECT_I::QS_TYPE_GROUP_MIN_MAX item.cc: - Simplifed Item::split_sum_func2() - Split test to make them faster and easier to read - Changed last argument to Item::split_sum_func2() from bool to int to allow more flags - Added flag argument to Item::split_sum_func() to allow on to specify if the item was in the SELECT part - Changed split_sum_func2() to do nothing if called with an argument that is not a sum function and doesn't include sum functions, if we are not an argument to SELECT. opt_range.cc: - Simplified get_best_group_min_max() by calcuating first how many group_by elements. - Use join->group instead of join->group_list to test if group by, as join->group_list may be NULL if everything was optimized away. sql_select.cc: - Added an extra remove_const() pass for GROUP BY arguments before make_join_statistics() in case of one table SELECT. - Use group instead of group_list to test if group by, as group_list may be NULL if everything was optimized away. - Moved printing of "Error in remove_const" to remove_const() instead of having it in caller. - Simplified some if tests by re-ordering code. - update_depend_map_for_order() and remove_const() fixed to handle the case where make_join_statistics() has not yet been called (join->join_tab is 0 in this case)
