3fa0dd23e0 A fix and a test case for Bug#14210 "Simple query with > operator on
large table gives server crash": make sure that when a MyISAM temporary
table is created for a cursor, it's created in its memory root,
not the memory root of the current query.

  A test case for Bug#14210 "Simple query with > operator on large table

sql/handler.cc:
  - rewrite get_new_handler to accept a memory root and use it for

sql/sql_base.cc:

sql/sql_select.cc:
  - the actual fix for Bug#14210. In create_myisam_from_heap we should
  create the new table handler in TABLE::mem_root, not in THD::mem_root:
  the latter is freed shortly after cursor is open.
  - adjust create_tmp_table to explicitly supply &table->mem_root
  to get_new_handler when creating a handler for a new temporary table

a7ed6ce441 Fix bug #14138 ROLLUP and PROCEDURE ANALYSE() hang server
Procedure analyse() redefines select's fields_list. setup_copy_fields() assumes
that fields_list is a part of all_fields_list. Because select have only 
3 columns and analyse() redefines it to have 10 columns, int overrun in
setup_copy_fields() occurs and server goes to almost infinite loop.

Because fields_list used not only to send data ad fields types, it's wrong 
to allow procedure redefine it. This patch separates select's fileds_list 
and procedure's one. Now if procedure is present, copy of fields_list is 
created in procedure_fields_list and it is used for sending data and fields.

6020281e95 Fix bug#14186 select datefield is null not updated
Date field was declared as not null, thus expression 'datefield is null'
was always false. For SELECT special handling of such cases is used. 
There 'datefield is null' converted to 'datefield eq "0000-00-00"'.

In mysql_update() before creation of select added remove_eq_conds() call.
It makes some optimization of conds and in particular performs conversion
from 'is null' to 'eq'. 
Also remove_eq_conds() makes some evaluation of conds and if it founds that
conds is always false then update statement is not processed further.
All this allows to perform some update statements process faster due to
optimized conds, and not wasting resources if conds known to be false.

0390de8672 Fix bug #13855 select distinct with group by caused server crash
DISTINCT wasn't optimized away and caused creation of tmp table in wrong
case. This result in integer overrun and running out of memory.

Fix backported from 4.1. Now if optimizer founds that in result be only 1
row it removes distinct.

b896d3343b Move handling of suffix_length from strnxfrm_bin() to filesort to ensure proper sorting of all kind of binary objects
field::sort_key() now adds length last for varbinary/blob
VARBINARY/BLOB is now sorted by filesort so that shorter strings comes before longer ones
Fixed issues in test cases from last merge



mysql-test/r/select.result:
  Change column name in test to get GROUP BY to use the alias
mysql-test/r/type_blob.result:
  Test BLOB and VARCHAR sorting
mysql-test/t/select.test:
  Change column name in test to get GROUP BY to use the alias
  Drop used tables at start of test
  Don't use table names 'a', 'b' or 'c'
mysql-test/t/type_blob.test:
  Test BLOB and VARCHAR sorting
sql/field.cc:
  Store length last in VARBINARY() and BLOB() columns to get shorter strings sorted before longer onces
sql/field.h:
  Added method 'sort_length()' to allow one to have length bytes last for VARBINARY/BLOB to get these to sort properly
sql/filesort.cc:
  Use 'sort_length()' instead of 'pack_length()' to get length of field.
  Store suffix_length last for varbinary (blob) objects.
  The above ensures that BLOB/VARBINARY are correctly sorted (shorter strings before longer ones)
sql/sql_class.h:
  Added sort suffix length (to get varbinary/blob to sort correctly)
sql/sql_select.cc:
  Use sort_length() instead of pack_lengths()
strings/ctype-bin.c:
  Don't let strnxfrm_bin store length last
  Better to do it in MySQL field object to ensure it's done properly for all cases
