  • Revision #3367 Tue 2012-04-10 08:30:20 +0200
    • tweak the test to pass, until the upstream MySQL Bug #61209 is *completely* fixed (see my comments starting from [9 Apr 22:18])

    • Revision #2502.546.39 Sat 2012-04-07 02:29:04 -0700
      • Fixed Bug #972973.
      • When the function free_tmp_table deletes the handler object for a temporary table the field TABLE::file for this table should be set to NULL. Otherwise an assertion failure may occur.
    • Revision #2502.546.38 [merge] Fri 2012-04-06 16:40:39 -0700
      • Merge.
      • Revision #2502.555.1 Fri 2012-04-06 15:08:09 -0700
        • Fixed Bug #915222
        • This bug happened because the function find_field_in_view formed autogenerated names of view columns without a possibility to roll them back. In some situation it could cause memory misuses reported by valgrind or even crashes.
    • Revision #2502.546.37 Fri 2012-04-06 13:18:12 +0300
      • Unused method removed.

        • Revision #2502.554.4 Fri 2012-04-06 13:31:33 +0500
          • MDEV-80 Memory engine table full at much less than max_heap_table_size with btree index.
          • RB-tree index in the MEMORY table fails if it grews over 4G.
          • That happened because the old_allocated variable in hp_rb_write_key() had the uint type. Changed with the 'size_t' type to be same as the 'rb_tree.allocated'.
          • per-file comments:
            • storage/heap/hp_write.c
          • MDEV-80 Memory engine table full at much less than max_heap_table_size with btree index.
            • uint->size_t for the 'old_allocated'.
    • Revision #2502.546.35 [merge] Thu 2012-04-05 23:07:18 +0200
    • Revision #2502.546.34 Thu 2012-04-05 23:32:57 +0300
      • Fix of Bug #968720.
      • When a view/derived table is converted from merged to materialized the items from the used_item lists are substituted for items referring to the fields of the result of the materialization. The problem appeared with queries employing natural joins. Since the resolution of a natural join was performed only once the used_item list formed at the second execution of the query lacked the references to the fields that were used only in the equality predicates generated for the natural join.
    • Revision #2502.546.33 Wed 2012-04-04 21:35:34 +0400
      • Make test results stable.

        • Revision #2502.552.1 Mon 2012-04-02 21:41:54 +0400
          • Bug #913030: Optimizer chooses a suboptimal excution plan for Q18 from DBT-3
          • When doing join optimization, pre-sort the tables so that they mimic the execution order we've had with 'semijoin=off'.
          • That way, we will not get regressions when there are two query plans (the old and the new) that have indentical costs but different execution times (because of factors that the optimizer was not able to take into account).

        • Revision #2502.551.1 Wed 2012-04-04 00:14:07 +0300
          • Fixed Bug #970528 "Server crashes in my_strnncollsp_simple on LEFT JOIN with CSV table, TEXT field"
          • The main problem was a bug in CSV where it provided wrong statistics (it claimed the table was empty when it wasn't)
          • I also fixed wrong freeing of blob's in the CSV handler. (Any call to handler::read_first_row() on a CSV table with blobs would fail)

    • Revision #3354.1.3 Mon 2012-04-02 12:09:22 +0300
      • Fixed Bug #886484 "nowatch option for mysqld (allow systemd)"
      • Added a --nowatch (with aliases --no-watch and --no-auto-restart) option to mysqld_safe that causes it to exit after spawning mysqld. We don't need mysqld_safe to restart mysqld after a crash, because systemd can do that just fine.
