Subject: [PATCH 06/33] bug#28273: GROUP_CONCAT and ORDER BY: No warning when
 result gets truncated.

When using GROUP_CONCAT with ORDER BY, a tree is used for the sorting, as
opposed to normal nested loops join used when there is no ORDER BY.

The tree traversal that generates the result counts the lines that have been
cut down. (as they get cut down to the field's max_size)
But the check of that count was before the tree traversal, so no
warning was generated if the output is truncated.

Fixed by moving the check to after the tree traversal.


mysql-test/r/func_gconcat.result:
  bug#28273: correct result
mysql-test/t/func_gconcat.test:
  bug#28273: test case
sql/item_sum.cc:
  bug#28273: the fix

  Moved the code that outputs a warning to after temporary table (tree) is traversed.

 crash is the result of an attempt made by JOIN::optimize to evaluate the

  The crash is the result of an attempt made by JOIN::optimize to evaluate
  the WHERE condition when no records have been actually read.
  Such attempts could be observed only with EXPLAIN commands.
  Now at the optimization phase the WHERE condition is never evaluated if
  there is no record previously read from the table.

Subject: [PATCH 12/33] Bug#27573: MIN() on an indexed column which is always
 NULL sets _other_ results to NULL

For queries of the form SELECT MIN(key_part_k) FROM t1
WHERE key_part_1 = const and ... and key_part_k-1 = const,
the opt_sum_query optimization tries to
use an index to substitute MIN/MAX functions with their values according
to the following rules:
1) Insert the minimum non-null values where the WHERE clause still matches, or
3) A row of nulls

However, the correct semantics requires that there is a third case 2)
such that a NULL value is substituted if there are only NULL values for
key_part_k.

The patch modifies opt_sum_query() to handle this missing case.


mysql-test/r/func_group.result:
  Bug #27573: Correct result
mysql-test/t/func_group.test:
  Bug #27573: test case
sql/opt_sum.cc:
  Bug #27573:
  Added code that will try to read the
  first non-null value for a given complete-field prefix, second
  choice is to read the null, and lastly set the error code if no row
  is found.

  Fix bug#27833 "Bourne shell string comparison issue in scripts/make_win_bin_dist":

  Several string comparisons could never yield true because they had an 'x' guard
  added to the variable but not to the constant value. Fix that by guarding both sides.

  Use this occasion to apply some corrections to the comments and the usage text.

  Also, ensure the ".pdb" file is always optional.

Subject: [PATCH 14/33] Bug#28208: Wrong result of a non-const STRING function
 with a const DATETIME function.

A wrong  condition was used to check that the
Arg_comparator::can_compare_as_dates() function calculated the value of the
string constant. When comparing a non-const STRING function with a constant
DATETIME function it leads to saving an arbitrary value as a cached value of
the DATETIME function.

Now the Arg_comparator::set_cmp_func() function initializes the const_value
variable to the impossible DATETIME value (-1) and this const_value is
cached only if it was changed by the Arg_comparator::can_compare_as_dates()
function.


mysql-test/t/type_datetime.test:
  Added a test case for the bug#28208: Wrong result of a non-const STRING function with a const DATETIME function.

mysql-test/r/events_bugs.result:
  Update results.
mysql-test/t/events_bugs.test:
  Make a stab at fixing events_bugs.test failure on Debian.
  The problem is purely in the race inherent in the test case: an
  event that was started doesn't go away fast enough and clutters the
  processlist. This patch remove the part of the event that
  we can not wait on synchronously (there is no table 'hashed_num'
  referenced anywhere).

Subject: [PATCH 21/33] Ensure that the 5.1 version of
 "scripts/make_win_bin_dist" depends on 5.0, so that changes from 5.0
 propagate (on merge) into the 5.1 version.

BitKeeper/deleted/.del-make_win_bin_dist-HIDE:
  Delete: scripts/make_win_bin_dist-HIDE
scripts/make_win_bin_dist:
  Transfer the current contents of the 5.1 version into this file.

  This is *no* contents change, its *only* purpose is to ensure that the 5.1 version
  of this file depends on the 5.0 version, and changes from 5.0 propagate properly
  into 5.1.

Subject: [PATCH 23/33] Fixed bug #28337: wrong results for grouping queries
 with correlated subqueries in WHERE conditions. This bug was introduced by
 the patch for bug 27321.

mysql-test/r/subselect.result:
  Added a test case for bug #28337.
mysql-test/t/subselect.test:
  Added a test case for bug #28337.
sql/item.cc:
  Fixed bug #28337: wrong results for grouping queries with correlated
  subqueries in WHERE conditions.
  This bug was introduced by the patch for bug 27321.

  Now in the Item_field::fix_outer_field function we create an Item_outer_ref
  object for an outer reference only if it is used in the SELECT list or
  in the HAVING clause of the subquery against which the reference is resolved.

Subject: [PATCH 25/33] Bug#28261: Wrong DATETIME comparison result when the
 GET_USER_VAR function is involved.

The Arg_comparator::compare_datetime() comparator caches its arguments if
they are constants i.e. const_item() returns true. The
Item_func_get_user_var::const_item() returns true or false based on
the current query_id and the query_id where the variable was created.
Thus even if a query can change its value its const_item() still will return
true. All this leads to a wrong comparison result when an object of the
Item_func_get_user_var class is involved.

Now the Arg_comparator::can_compare_as_dates() and the
get_datetime_value() functions never cache result of the GET_USER_VAR()
function (the Item_func_get_user_var class).


mysql-test/t/type_datetime.test:
  A test case is added for the bug#28261: Wrong DATETIME comparison result when the GET_USER_VAR function
  is involved.

Increase STACK_BUFF_ALLOC to avoid execution_constants test failure on the hpita2.


sql/mysql_priv.h:
  Fix for bug #21476: stack overflow crashes server; error-message stack reservation too small
    - due to the failing execution_constants test on the hpita2,
      increase STACK_BUFF_ALLOC, that is used in the Item_func::fix_fields() to
      allocate on the stack a "dummy" buffer large enough for the corresponding exec.

Subject: [PATCH 32/33] Fix for bug #23810: Server crashes on various "show
 status ..." commands

We access some variable values using casts like *(long *) buff
that may cause crashes on some platforms (e.g. solaris 64) if buff is
not properly aligned.
Fix: align the buffer used.


include/my_global.h:
  Fix for bug #23810: Server crashes on various "show status ..." commands
    - MY_DIV_UP(A, B) macro introduced, which devides A then rounds up by B.
    - MY_ALIGNED_BYTE_ARRAY(N, S, T) macro introduced, which declares an S-byte long
      (aligned) N array of type T.

  Fix for bug #23810: Server crashes on various "show status ..." commands
