not logged
        
Errors encountered during initialization of the SSL subsystem
are printed to stderr, rather than to the error log.
        
This patch adds a parameter to several SSL init functions to
report the error (if any) out to the caller. The function
init_ssl() in mysqld.cc is moved after the initialization of
the log subsystem, so that any error messages can be logged to
the error log. Printing of messages to stderr has been 
retained to get diagnostic output in a client context.


include/violite.h:
  Adding an enumeration for the various errors that can
  occur during initialization of the SSL module.
sql/mysqld.cc:
  Adding more logging of SSL init errors, and moving
  init_ssl() till after initialization of logging 
  subsystem.
vio/viosslfactories.c:
  Define error strings, provide an access method for these
  strings, and maintain an error parameter in several funcs
  to return the error (if any) to the caller.

When during the optimization an item is moved to the upper select
the item's context left unchanged. This caused wrong result in the 
PS/SP mode.
The Item_ident::remove_dependence_processor now sets the context
of the select to which the item is moved to.

sql/item.cc:
  Bug#46051: Incorrectly market field caused wrong result.
  The Item_ident::remove_dependence_processor now sets the context
  of the select to which the item is moved to.

In a subselect all fields from outer selects are marked as dependent on
selects they are belong to. In some cases optimizer substitutes it for an
equivalent expression. For example "a_field IN (SELECT outer_field)" is
substituted with "a_field = outer_field". As we moved the outer_field to the
upper select it's not really outer anymore. But it was left marked as outer.
If exists an index over a_field optimizer choose wrong execution plan and thus
return wrong result.

Now the Item_in_subselect::single_value_transformer function removes dependent
marking from fields when a subselect is optimized away.

  Added a test case for the bug#46051.

  marking from fields when a subselect is optimized away.

This patch is a follow up to http://lists.mysql.com/commits/76678.
When an allocation failure occurs for the buffer in the dynamic
array, an error condition was being set. The dynamic array is
usable even if the memory allocation fails. Since in most cases
the thread can continue to work without any problems the error
condition should not be set here.

This patch adds logic to remove the error condition from being set
when the memory allocation for the buffer in dynamic array fails.

mysys/array.c:
  Bug#43572 Handle failures from hash_init
  
  Remove the MY_WME flag from the call to malloc in order to
  prevent the error status from being set in the init_dynamic_array
  method. Since this memory allocation failure is no longer
  fatal this method has been modified to return FALSE
  (indicate success) irrespective of array->buffer being
  allocated.

  sort_buffer_size cannot allocate

The NULL return from tree_insert() (on low memory) was not
checked for in Item_func_group_concat::add(). As a result
on low memory conditions a crash happens.

Fixed by properly checking the return code.

       
Fixed various compilation warnings when compiling on a 
 64 bit windows.

Fixed the following problems:
1. cmake 2.6 warning because of a changed default on
how the dependencies to libraries with a specified 
path are resolved.
Fixed by requiring cmake 2.6.
2. Removed an obsolete pre-NT4 hack including defining
Windows system defines to alter the behavior of windows.h.
3. Disabled warning C4065 on compiling sql_yacc.cc because
of a know incompatibility in some of the newer bison binaries.

          match against.


Server crashes when executing prepared statement with duplicating
MATCH() function calls in SELECT and ORDER BY expressions, e.g.:
SELECT MATCH(a) AGAINST('test') FROM t1 ORDER BY MATCH(a) AGAINST('test')

This query gets optimized by the server, so the value returned
by MATCH() from the SELECT list is reused for ORDER BY purposes.
To make this optimization server is comparing items from
SELECT and ORDER BY lists. We were getting server crash because
comparision function for MATCH() item is not intended to be called
at this point of execution.

In 5.0 and 5.1 this problem is workarounded by resetting MATCH()
item to the state as it was during PREPARE.

In 6.0 correct comparision function will be implemented and
duplicating MATCH() items from the ORDER BY list will be
optimized.

mysql-test/r/fulltext.result:
  Updated with the test case for Bug#37740
mysql-test/t/fulltext.test:
  A test case for Bug#37740.
sql/item_func.h:
  True initialization of 'table' happens in ::fix_fields(). As
  Item_func_match::eq() may be called before ::fix_fields(), it is
  expected that 'table' is initialized to 0 when it is reused.
  
  This is mostly affecting prepared statements, when the same item
  doesn't get destroyed, but rather cleaned up and reused.

without error

When using quick access methods for searching rows in UPDATE or 
DELETE there was no check if a fatal error was not already sent 
to the client while evaluating the quick condition.
As a result a false OK (following the error) was sent to the 
client and the error was thus transformed into a warning.

Fixed by checking for errors sent to the client during 
SQL_SELECT::check_quick() and treating them as real errors.

Fixed a wrong test case in group_min_max.test
Fixed a wrong return code in mysql_update() and mysql_delete()

GHz.

The crash happend because for views which are joins
we have table_list->table == 0 and 
table_list->table->'any method' call leads to crash.
The fix is to perform table_list->table->file->extra()
method for all tables belonging to view.


mysql-test/r/view.result:
  test result
mysql-test/t/view.test:
  test case
sql/sql_insert.cc:
  added prepare_for_positional_update() function
  which updates extra info about primary key for
  tables belonging to view.

Details:
- Add "sync_slave_with_master" at test end
- Restore the initial value of log_bin_trust_function_creators

without proper formatting
      
The problem is that a suitably crafted database identifier
supplied to COM_CREATE_DB or COM_DROP_DB can cause a SIGSEGV,
and thereby a denial of service. The database name is printed
to the log without using a format string, so potential
attackers can control the behavior of my_b_vprintf() by
supplying their own format string. A CREATE or DROP privilege
would be required.
      
This patch supplies a format string to the printing of the
database name. A test case is added to mysql_client_test.


sql/sql_parse.cc:
  Added format strings.
tests/mysql_client_test.c:
  Added new test case.

                               But Should Be "Zero Rows"


After applying the innodb snapshot 5.0-ss5406 for bug#40565, the windows push build
tests failed because of the missing cast of void * pointer in row0sel.c file

Informed the innodb developers and received patch by email.

innobase/row/row0sel.c:
  Cast the default_rec which is a void * pointer

  branches/5.1: When converting a record to MySQL format, copy the default
  column values for columns that are SQL NULL.  This addresses failures in
  row-based replication (Bug #39648).

  row_prebuilt_t: Add default_rec, for the default values of the columns in
  MySQL format.

  row_sel_store_mysql_rec(): Use prebuilt->default_rec instead of
  padding columns.
