63982db93c Better bugfix for "HAVING when refering to RAND()" (Bug #8216)
Ensure that references in HAVING, ORDER BY or GROUP BY are calculated after fields in SELECT.
This will ensure that any reference to these has a valid value.
Generalized the code for split_sum_func()

mysql-test/r/group_by.result:
  More complicated test to assure that rand() is only calulated once
mysql-test/r/user_var.result:

sql/item.cc:
  Better bugfix for "HAVING when refering to RAND()"
  This will ensure that when refering to things like RAND() in HAVING through an alias we will not recalculate that rand() value in the HAVING part but use the value in the row

Bug#7834 Illegal mix of collations in IN operator
  IN was the first function supporting 
  character set convertion.
  agg_arg_charsets() was written afterwards,
  which is more flexible.
  Now IN just reuses this function.

cd89ed9ab6 1. Item now uses my_charset_bin by default,
not default_charset_into. It fixes the
problem that in some cases numbers where
treated as CHAR(N), not as BINARY(N), e.g.
wrong 'charsetnr' when sent to the client side.
2. IFNULL didn't aggregate argument charsets
and collations, so IFNULL(1,'a') produced
a CHAR(N). Now produces a BINARY(N).
3. SELECT PROCEDURE ANALIZE now returns
BINARY columns, which is much better than it worked
previously: CHAR with the default character set.
But in the future it's worth to fix the fields
'Field_name' and 'Optimal_fieldtype' to use UTF8,
and 'Min_value' and 'Max_value' to inherit their charsets
from the original items. But it is not important,
and BINARY(N) is OK for now.
4. Tests were fixed accordingly. No new tests were
made, as the old onces cover everything.

a4d840a09c subselect.result, subselect.test:
Added test cases for bug #7351.
item_cmpfunc.cc:
  Fixed bug #7351: incorrect result for a query with a
  subquery returning empty set.
  If in the predicate v IN (SELECT a FROM t WHERE cond)
  v is null, then the result of the predicate is either
  INKNOWN or FALSE. It is FALSE if the subquery returns
  an empty set.
item_subselect.cc:
  Fixed bug #7351: incorrect result for a query with a
  subquery returning empty set.
  The problem was due to not a quite legal transformation
  for 'IN' subqueries. A subquery containing a predicate
  of the form
  v IN (SELECT a FROM t WHERE cond)
  was transformed into
  EXISTS(SELECT a FROM t WHERE cond AND (a=v OR a IS NULL)).
  Yet, this transformation is valid only if v is not null.
  If v is null, then, in the case when
  (SELECT a FROM t WHERE cond) returns an empty set the value
  of the predicate is FALSE, otherwise the result of the
  predicate is INKNOWN.
  The fix resolves this problem by changing the result
  of the transformation to
  EXISTS(SELECT a FROM t WHERE cond AND (v IS NULL OR (a=v OR a IS NULL)))
  in the case when v is nullable.
  The new transformation prevents applying the lookup
  optimization for IN subqueries. To make it still
  applicable we have to introduce guarded access methods.

The problem in 4.1 was the same as in 4.0 - fix_fields() not called for created Item_ref.

Item_ref is used by subselects).

435b20aa68 Simpler arena swapping code
Now thd->mem_root is a pointer to thd->main_mem_root and THR_MALLOC is a pointer to thd->mem_root.
This gives us the following benefits:
- Allow us to easily detect if arena has already been swapped before (this fixes a bug in setup_conds() where arena was swaped twice in some cases)
- Faster swaps of arenas (as we don't have to copy the whole MEM_ROOT)
- We don't anymore have to call my_pthread_setspecific_ptr(THR_MALLOC,...) to change where memory is alloced. Now it's enough to set thd->mem_root

853c2c788c A lot of fixes for prepared statements (PS):
New mysqltest that can run mysqltest with PS
Added support for ZEROFILL in PS
Fixed crash when one called mysql_stmt_store_result() without a preceding mysql_stmt_bind_result()
Updated test cases to support --ps-protocol
(Some tests are still run using old protocol)
Fixed crash in PS when using SELECT * FROM t1 NATURAL JOIN t2...
Fixed crash in PS when using sub queries
Create table didn't signal when table was created. This could cause a "DROP TABLE created_table" in another thread to wait "forever"
Fixed wrong permissions check in PS and multi-table updates (one could get permission denied for legal quries)
Fix for PS and SELECT ... PROCEDURE
Reset all warnings when executing a new PS query
group_concat(...ORDER BY) didn't work with PS
Fixed problem with test suite when not using innodb

client/Makefile.am:

client/mysqltest.c:
  Added support for testing of prepared statements (with --ps-protocol)
  Main code was done by Kent, I did mainly some cleanups and minor bug fixes
  New test commands:

  NOTE: new code still has some things that needs to be cleaned up.
  For example run_query_stmt_handle_error() should be made more general so that same code can be used also by 'normal' queries

8fa6f37a29 A fix for Bug#5748 "Prepared statement with BETWEEN and bigint values
crashes mysqld": implementation for a generic item tree modifications
registry. Every item tree modification which should be rolled back for
subsequent execution of a prepared statement or stored procedure should
be saved in the registry. All such modifications are rolled back at once
during cleanup stage of PS.
Actual fix for the bug just adds a call to register modifications to
convert_constant_item.
Post review fixes implemented.

sql/field.cc:
  Removed not used variable
  Portability fix (cast)
  Simplified Field_str::double()
  Simple indentation cleanups
sql/field.h:
  Removed not needed class variable
sql/item_cmpfunc.cc:
  Indentation fix
sql/item_strfunc.cc:
  Use on stack variable for Item_str_func::val() instead of str_value.
  This makes it safe to use str_value inside the Item's val function.
  Cleaned up LEFT() usage, thanks to the above change
sql/item_sum.cc:
  Indentation cleanups
sql/protocol.cc:
  Added missing cast
sql/sql_acl.cc:
  Indentatin cleanups.
  Added missing cast
  Simple optimization of get_sort()
sql/sql_select.cc:
  Don't use 'ref' to search on text field that is not of type BINARY (use 'range' instead).
  The reson is that for 'ref' we use 'index_next_same' to read the next possible row. 
  For text fields, rows in a ref may not come in order, like for 'x', 'x\t' 'x ' (stored in this order) which causes a search for 'column='x ' to fail
sql/tztime.cc:
  Simple cleanup
strings/ctype-bin.c:
  Comment fixes
strings/ctype-mb.c:
  Changed variable names for arguments

095b686c09 Fix for bug#4912 "mysqld crashs in case a statement is executed
a second time". The bug was caused by incompatibility of
negations elimination algorithm and PS: during first statement 
execute a subtree with negation was replaced with equivalent 
subtree without NOTs.
The problem was that although this transformation was permanent, 
items of the new subtree were created in execute-local memory.
The patch adds means to check if it is the first execute of a
prepared statement, and if this is the case, to allocate items
in memory of the prepared statement.
The implementation:
- backports Item_arena from 5.0
- adds Item_arena::is_stmt_prepare(), 
  Item_arena::is_first_stmt_execute().
- deletes THD::allocate_temporary_pool_for_ps_preparing(),
  THD::free_temporary_pool_for_ps_preparing(); they
  were redundant.
and adds a few invariants:
- thd->free_list never contains junk (= freed items)
- thd->current_arena is never null. If there is no
  prepared statement, it points at the thd. 
The rest of the patch contains mainly mechanical changes and
cleanups.

7fbc796d4a Bug#4521: unique key prefix interacts poorly with utf8.
Fix for binary collations for MyISAM and HEAP BTREE.
This patch also changes trailing spaces behaviour for
binary collations. Binary collations now have PAD 
characteristic too.
