Append the patch for resolving the problems, which have been brought by commiting bug#45214.

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

        
The "get_master_version_and_clock(...)" function in sql/slave.cc ignores 
error and passes directly when queries fail, or queries succeed 
but the result retrieved is empty.
  
The "get_master_version_and_clock(...)" function should try to reconnect master
if queries fail because of transient network problems, and fail otherwise.
The I/O thread should print a warning if the some system variables do not 
exist on master (very old master)

mysql-test/extra/rpl_tests/rpl_get_master_version_and_clock.test:
  Added test file for bug #45214
mysql-test/suite/rpl/r/rpl_get_master_version_and_clock.result:
  Added test result for bug #45214
mysql-test/suite/rpl/t/rpl_get_master_version_and_clock.test:
  Added test file for bug #45214
sql/slave.cc:
  The 'is_network_error()' function is added for checking if the error is caused by network.
  Added a new return value (2) to 'get_master_version_and_clock()' function result set 
  to indicate transient network errors when queries fail, and the caller should 
  try to reconnect in this case.

          table

The MERGE table storage engine does not support the HA_CAN_SQL_HANDLE feature
and any attempt to open the merge table will fail with ER_ILLEGAL_HA.

After an error occurred the tables that was opened must be closed again
or they will be left in an inconsistent state. However, the assumption
made in the code for closing and register handler tables was that only
one table will be opened, and this is not true for MERGE tables which
will cause multiple tables to open.

The next time a SELECT operation was issued on the merge table it
caused the system to freeze.

This patch fixes this issue by making sure that all tables which
are opened also are closed in the event of an error.

sql/sql_handler.cc:
  * mysql_ha_open() was never ment to open more than one table. If we encounter more tables, we should
    close all tables related to the current substatement and raise an exception.

Merge Konstantin's patch and add a test case.

failed"

Do not assume that SQL prepared statements always run in text protocol.
When invoked from a stored procedure, which is itself invoked
by means of prepared CALL statement, the protocol may be binary.
Juggle with the protocol only when we want to change it
to binary in COM_STMT_EXECUTE, COM_STMT_PREPARE.

This is a backport from 5.4/6.0, where the bug was fixed
as part of WL#4264 "Backup: Stabilize Service Interface" 

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.

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.

"create as select" (innodb table)

Problem: code constructing "CREATE TABLE..." statement
doesn't take into account that current database is not set
in some cases. That may lead to a server crash.

Fix: check if current database is set.


mysql-test/extra/binlog_tests/binlog.test:
  Fix for bug#45998: database crashes when running
  "create as select" (innodb table)
    - test case.

sql/sql_show.cc:
  Fix for bug#45998: database crashes when running
  "create as select" (innodb table)
    - added check if there's current database set.

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()
