  • Fixed .

    • This bug was introduced into in the December 2010 with the patch that added a new engine property: the ability to support virtual columns.

• Fri 2012-03-09 14:28:02 +0200

  • Added test case for "Assertion pageno < ((1ULL) <<` 40)' failed at ma_pagecache.c:3438: pagecache_read or table corruption on INSERT into a ucs2 table"

  • Added ucs2 test moved from maria3.test. ()

• Thu 2012-03-08 22:33:01 -0800

  • Fixed .

  • 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.

• Mon 2012-01-02 23:52:31 +0100

  • Fix embedded/windows tests- move COND_manager and LOCK_manager to sql_manager.cc, to prevent race condition that results into accessing already destroyed critical section

• Thu 2011-12-29 15:09:20 -0800

  • Fixed .

    • A table expression with a natural join or a USING clause is transformed into an equivalent expression with equi-join ON conditions. If a reference to a virtual column happened to occur only in these generated equi-join conditions then it was not erroneously marked in the TABLE::vcol_set bitmap.

    • This could lead to wrong results for queries containing natural join expressions or USING clauses.

• Wed 2011-12-28 18:47:01 -0800

  • Fixed .

  • The method Item_sum_num::fix_fields() calculated the value of the flag Item_sum_num::maybe_null in some cases incorrectly.

• Tue 2011-12-27 19:13:53 -0800

  • Fixed .

  • The MIN/MAX optimization cannot be applied to a subquery if its WHERE clause contains a conjunctive condition depending on an outer reference.

• Tue 2011-12-27 13:19:13 -0800

  • Fixed .

  • The MIN/MAX optimizer code from the function opt_sum_query erroneously did not take into account conjunctive conditions that did not depend on any table, yet were not identified as constant items. 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.

  • Supression condition made wider to cover some other system cases.

• Tue 2011-12-20 01:56:41 -0800

  • Fixed .

  • The function st_table::mark_virtual_columns_for_write() did not take into account the fact that for any table the value of st_table::vfield is 0 when there are no virtual columns in the table definition.

• Mon 2011-12-19 14:55:30 -0800

  • Fixed .

  • If the sorted table belongs to a dependent subquery then the function create_sort_index() should not clear TABLE:: select and TABLE::select for this table after the sort of the table has been performed, because these members are needed for the second execution of the subquery.

• [merge] Tue 2011-12-13 20:08:41 +0200

  • Merge with 5.1

  • Updated version number in configure

  • Mon 2011-12-12 16:28:16 +0100

  • Fixed ; Error in recovery with LOAD DATA + DELETE

• Mon 2011-12-12 12:36:46 +0200

  • Fixed

  • The range optimizer incorrectly chose a loose scan for group by when there is a correlated WHERE condition. This range access method cannot be executed for correlated conditions also with the "range checked for each record" because generally the range access method can change for each outer record. Loose scan destructively changes the query plan and removes the GROUP operation, which will result in wrong query plans if another range access is chosen dynamically.

• Thu 2011-12-08 12:05:52 +0200

  • Fixed

  • Analysis:

    • The class member QUICK_GROUP_MIN_MAX_SELECT::seen_first_key was not reset between subquery re-executions. Thus each subsequent execution continued from the group that was reached by the previous subquery execution. As a result loose scan reached end of file much earlier, and returned empty result where it shouldn't.
