The problem was increment of aborted_threads variable due to thd->killed which was set when threadpool connection was terminated . The fix is not to set thd->killed anymore, there is no real reason for doing it..
Added a test that checks that status variable aborted_clients does not grow for ordinary disconnects, and that successful KILL increments this variable.
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
tests for #977021 and #986977 added.
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.
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.
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.
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.
Moved test from main suite to the new suites.
Move tests from maria/t and maria/r to maria
mysql-test/mysql-test-run.pl:
Added support for the new suites
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)
mysql-test/r/csv.result:
Added new test case
mysql-test/r/partition_innodb.result:
Updated test results after fixing bug with impossible partitions and const tables
mysql-test/t/csv.test:
Added new test case
sql/sql_select.cc:
Cleaned up code for handling of partitions.
Fixed also a bug where we didn't threat a table with impossible partitions as a const table.
storage/csv/ha_tina.cc:
Allocate blobroot onces.
- 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).
Fixed failing tests in sys_vars as we have now stricter checking of setting of variables.

Background:
- as described in MySQL Internals Prepared Stored
(http://forge.mysql.com/wiki/MySQL_Internals_Prepared_Stored),
the Optimizer sometimes does destructive changes to the parsed
LEX-object (Item-tree), which makes it impossible to re-use
that tree for PS/SP re-execution.
- in order to be able to re-use the Item-tree, the destructive
changes are remembered and rolled back after the statement execution.
The problem, discovered by this bug, was that the objects representing
GROUP-BY clause did not restored after query execution. So, the GROUP-BY
part of the statement could not be properly re-initialized for re-execution
after destructive changes.
Those objects do not take part in the Item-tree, so they can not be saved
using the approach for Item-tree.
The fix is as follows:
- introduce a new array in st_select_lex to store the original
ORDER pointers, representing the GROUP-BY clause;
- Initialize this array in fix_prepare_information().
- restore the list of GROUP-BY items in reinit_stmt_before_use().
Fix the calculation of the next autoinc value when offset > 1. Some of the
results have changed due to the changes in the allocation calculation. The
new calculation will result in slightly bigger gaps for bulk inserts.
