      • MDEV-214 Bug #967242 Wrong result with JOIN, AND in ON condition, multi-part key, GROUP BY, subquery and OR in WHERE
      • The problem was in the code (update_const_equal_items()) which marked index parts constant independently of the place where the equality was used. In the test suite it marked t2_1.c part constant despite the fact that it connected by OR with other expression.
      • Solution is to mark constant only top equalities connected with AND.
    • Revision #2732.53.35 [merge] Wed 2012-05-02 17:06:30 +0200

      • Bug #982664 there are few broken clients that lie about their capabilities (for example, one of them sets client capabilities by copying server capabilities)
      • We cannot fix them - let's tolerate them
  • Revision #3510 Sun 2012-04-29 18:08:11 +0500
    • Bug #977021 ST_BUFFER fails with the negative D.
      • Points and lines should disappear if we got negative D.
      • To make it work properly inside the GEOMETRYCOLLECTION, we add the empty operation there.
    • Bug #986977 Assertion `!cur_p->event' failed in Gcalc_scan_iterator::arrange_event(int, int).
      • The double->inernal coord conversion produced -0 (minus zero) on some data.
      • That minus-zero produces invalid comparison results when compared agains plus-zero.
      • So we fixed the gcalc_set_double() to avoid it.
    • per-file comments:
      • mysql-test/r/gis-precise.result
        • result updated.
      • mysql-test/t/gis-precise.test
      • sql/gcalc_slicescan.cc
        • Bug #986977. The gcalc_set_double fixed to not produce minus-zero.
      • sql/item_geofunc.cc
        • Bug #977021. Add the NOOP for the disappearing features.
  • Revision #3509 Thu 2012-04-26 19:21:37 +0200
    • MDEV-216 Bug #976104 - Assertion `0' failed in my_message_sql on UPDATE IGNORE, or unknown error on release build
    • Don't send_error at the end of mysql_multi_update() if select failed.
    • The error, if there was any, was already sent by mysql_select
  • Revision #3508 Fri 2012-04-27 12:59:17 +0300
    • Fix Bug #985667, MDEV-229
    • Analysis:
      • The reason for the wrong result is the interaction between constant optimization (in this case 1-row table) and subquery optimization.
        • First the outer query is optimized, and 'make_join_statistics' finds that table t2 has one row, reads that row, and marks the whole table as constant. This also means that all fields of t2 are constant.
        • Next, we optimize the subquery in the end of the outer 'make_join_statistics'. The field 'f2' is considered constant, with value '3'. The subquery predicate is rewritten as the constant TRUE.
        • The outer query execution detects early that the whole query result is empty and calls 'return_zero_rows'. Since the query is with implicit grouping, we have to produce one row with special values for the aggregates (depending on each aggregate function), and NULL values for all non-aggregate fields. This function calls 'no_rows_in_result' to set each aggregate function to the default value when it aggregates over an empty result, and then calls 'send_data', which in turn evaluates each Item in the SELECT list.
        • When evaluation reaches the subquery predicate, it executes the subquery with field 'f2' having a constant value '3', and the subquery produces the incorrect result '7'.
    • Solution:
      • Implement Item::no_rows_in_result for all subquery predicates. In order to make this work, it is also needed to make all val_* methods of all subquery predicates respect the Item_subselect::forced_const flag. Otherwise subqueries are executed anyways, and override the default value set by no_rows_in_result with whatever result is produced from the subquery evaluation.
  • Revision #3507 [merge] Mon 2012-04-23 20:37:44 +0200
    • merge
    • Revision #3505.1.1 Fri 2012-04-20 21:09:16 +0200
      • Bug #983285 - incompatibility in frm in case of VIEWs with non-default ALGORITHM option.
      • As part of derived tables redesign, values for VIEW_ALGORITHM_MERGE and VIEW_ALGORITHM_TMPTABLE have changed from (former values 1 rsp 2 , new values 5 rsp 9).
      • This lead to the problem that views, created with version 5.2 or earlier would not work in all situations (e.g "SHOW CREATE VIEW"), or with mysqldump.
      • The fix is to restore backward compatibility for the from file, and convert algorithm={1,2} in the frm to {5,9} when reading .frm from disk, and store backward compatible values when writing from to disk.
      • Also allow processing correct processing for "invalid" .frms created with MariaDB 5.3/5.5 GA releases (where algorithm stored in memory matched the one stored in frm).
  • Revision #3506 Mon 2012-04-23 09:45:27 +0200
    • MDEV-207 Install headers required to build external storage plugins
    • install all private headers in mysql/private/

    • Fixed incorrect type casting which made all fields (except very first) changes to materialized table incorrect.
    • Saved list of view/derived table used items after expanding '*'.
  • Revision #3504 Thu 2012-04-19 05:37:16 +0400
    • Bug #978479: Wrong result (extra rows) with derived_with_keys+loosescan+semijoin=ON, materialization=OFF
    • Part#2: Don't try to construct a LooseScan access on indexes that do not guarantee index-ordered reads.
  • Revision #3503 Thu 2012-04-19 04:50:32 +0400
    • BUG#978479: Wrong result (extra rows) with derived_with_keys+loosescan+semijoin=ON, materialization=OFF
    • Part#1: make EXPLAIN's plan match the one by actual execution:
    • Item_subselect::used_tables() should return the same value irrespectively of whether we're running an EXPLAIN or a SELECT.

        • This can result in bad deadlocks (e.g loader lock), seen in latest crash reports.
