* cleanup: handler::key_readSergei Golubchik2017-02-131-1/+1
| | | | | | * rename to "keyread" (to avoid conflicts with tokudb), * change from bool to uint and store the keyread index number there * provide a bool accessor to check if keyread is enabled
* MDEV-11836 vcol.vcol_keys_myisam fails in buildbot and outsideSergei Golubchik2017-02-131-2/+2
| | | | | | | move TABLE::key_read into handler. Because in index merge and DS-MRR there can be many handlers per table, and some of them use key read while others don't. "keyread" is really per handler, not per TABLE property.
* This is the consolidated patch for mdev-8646:bb-10.2-mdev8646Igor Babaev2016-02-091-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | "Re-factor the code for post-join operations". 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.

This patch fixes so that we always include my_global.h or my_config.h before we include any other files. Other things: - Removed #include <my_global.h> in some include files; Better to always do this at the top level to have as few "always-include-this-file-first' files as possible. - Removed usage of some include files that where already included by my_global.h or by other files. client/mysql_plugin.c: Use my_global.h first client/mysqlslap.c: Remove duplicated include files extra/comp_err.c:

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If in the where clause of the a query some comparison conditions on the field under a MIN/MAX aggregate function contained constants whose sizes exceeded the size of the field then the query could return a wrong result when the optimizer had chosen to apply the MIN/MAX optimization. With such conditions the MIN/MAX optimization still could be applied, yet it would require a more thorough analysis of the keys built to find the value of MIN/MAX aggregate functions with index look-ups. The current patch just prohibits using the MIN/MAX optimization in this situation.

These could be items containing rand() or PS/SP parameters. These items are supposed to be evaluated at the execution phase. That's why if such conditions can be extracted from the WHERE condition the MIN/MAX optimization is not applied as currently it is always done at the optimization phase. (In 5.3 expensive subqueries are also evaluated only at the execution phase. So, if a constant condition with such subquery can be extracted from the WHERE clause the MIN/MAX optimization should not be applied in 5.3.) IF an IN/ALL/SOME predicate with a constant left part is transformed into an EXISTS subquery the resulting subquery should not be considered uncacheable if the right part of the predicate is not uncacheable. Backported the function dbug_print_item() from 5.3. The function is used only for debugging.

The general pattern is that some optimization requires the evaluation of some condition (e.g. the WHERE clause), and this condition contains a subquery, such that the subquery itself requires a temporary table for its execution. During the subquery execution the original tables in the FROM clause are replaced by the temporary table needed for the final GROUP or ORDER operation. All this happens during optimization of the outer query. Later when EXPLAIN is run for the subquery, explain attempts to print the name of the tables in the FROM clause, but it finds there a temporary table without a corresponding TABLE_LIST object. The attempt to print the name of a NULL table list results in a crash. Solution: This patch extends the fix to bug lp:702301, and dissalows constant substitution of aggregate functions if the filter condition used to check MIN/MAX keys is an expensive condition.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The problem was that optimization code did not take into account later feature when instad of NOT before BETWEEN it has negated flag into the Item_func_between inherited from Item_func_neg_opt. So optimizer tried process NOT BETWEEN as BETWEEN. The patch just switches off the optimisation for NOT BETWEEN as it was before when NOT function was really used.

Commented out the queries from multi_update, view, subselect_sj, func_str, derived_view, view_grant that failed either with crashes in ps-protocol or with wrong results. The failures are clear indications of some bugs in the code and these bugs are to be fixed.
