The wait_for_ndb_to_binlog.inc include file used by the blow rpl_tests
common for rpl and rpl_ndb suite is simply doing a "sleep 5", this is
not deterministic and wastes lot of test time uneccessarily. The test
should be rewritten to check if the condition it wait for has been
reached or not.

For NDB engine all events will be added by NDB injector so tests only 
can continue after injector is ready, this test waits for proper
injector thread state.

Problem : The basic problem is the way the thread sleeps in mysql-5.5 and also in mysql-5.1
          when we execute a stop slave on windows platform.
          On windows platform if the stop slave is executed after the master dies, we have 
          this long wait before the stop slave return a value. This is because there is a 
          sleep of the thread. The sleep is uninterruptable in the two above version,
          which was fixed by Davi patch for the BUG#11765860 for mysql-trunk. Backporting 
          his patch for mysql-5.5 fixes the problem. 

Solution : A new pair of mutex and condition variable is introduced to synchronize thread 
           sleep and finalization. A new mutex is required because the slave threads are 
           terminated while holding the slave thread locks (run_lock), which can not be 
           relinquished during termination as this would affect the lock order.

  Use a timed wait on a condition variable to implement a interruptible sleep. 
  The wait is registered with the THD object so that the thread will be woken 
  up if killed.

Introducing new collations:
utf8_general_mysql500_ci and ucs2_general_mysql500_ci,
to reproduce behaviour of utf8_general_ci and ucs2_general_ci
from mysql-5.1.23 (and earlier).

The collations are added to simplify upgrade from mysql-5.1.23 and earlier.

Note: The patch does not make new server start over old data automatically.
Some manual upgrade procedures are assumed.

Paul: please get in touch with me to discuss upgrade procedures
when documenting this bug.

Thank you Davi!

- Fixed the checks to properly check for plugin_dir containing a trailing slash or backslash.
- Fixed a under-configuration in udf_skip_grants that was preventing the test 
  from running even when there was a udf plugin.

The issue is that xa.test failed sporadically on some platforms.
The reason for the test failure is a race condition in xa.test.
The race condition occures between connection that executes statement
INSERT INTO t2 SELECT FROM t1 and other connection that tries to run
statements DELETE FROM t1 and COMMIT. If COMMIT statement had been executed
before the statement INSERT INTO t2 SELECT FROM t1 was locked by lock
on table t1 (as a result of query from table t1) then the INSERT statement
is executed successfully and a following test for deadlock would failed.

This patch fixes this race condition by moving COMMIT statement after commit
of distributed transaction from concurrent session.

If an error message contains '\' backslash it is displayed correctly
through show-slave-status or
query_get_value(SHOW SLAVE STATUS, Last_IO_Error, 1);. But when
SELECT REPLACE(...) is applied backslash is escaped resulting in a
different test output.

Disabled backslash escape on show_slave_status.inc and replaced '\' for
'/' using replace_regex function in order to achieve the same test
output when different path separators are used.

On some kernel versions native aio operations are not supported on
tmpfs. Check this during start up and fall back to simulated aio.

The server crashes when receiving a COM_BINLOG_DUMP command with a position of 0 or
larger than the file size.
The execution proceeds to an error block having the last read replication coordinates 
pointer be NULL and its dereferencing crashed the server.

Fixed with making "public" previously used only for heartbeat coordinates.

  Making `coord' to carry the last read from binlog event coordinates

  Renaming, small cleanup and simplifying the code after if (coord) becomes unnecessary.
  Adding yet another 3rd pair of coordinates - the starting replication - 
  into error text.

  and cryptic error 1126 message

The problem was that dlopen() related code was using just a subset 
of the path normalization routines used in other places.
Fixed the expansion of the pre-dlopen() behavior for plugins and UDFs
to use a platform-dependent consistent encoding of the paths.
Fixed the error dlopen() error handling to take the correct error message
and strip off the trailing newline character(s).
Fixed tests to do a platform independent replace of directories and to 
account for the traling slash.

Test extra/rpl_tests/rpl_extra_col_master.test (used by
rpl_extra_col_master_*) ends with the active connection pointing to the
slave. Thus, the two last tests never succeed in changing the binlog
format of the master away from 'row'. With correct active connection
(master) tests fail for binlog 'statement' and 'mixed' formats.

Tests rpl_extra_col_master_* only run when binary log format is
row.  Statement and mix replication do not make sense in this
tests since it will try to execute statements on columns that do
not exist.  This fix is basically a backport from mysql-5.5, see
changes done as part of BUG 39934.

When mode==BUF_KEEP_OLD, buffered inserts are being merged to the page.
It is possible that a read request for a page was pending while the page
was freed in DROP INDEX or DROP TABLE. In these cases, it is OK (although
useless) to merge the buffered changes to the freed page.

ISSUES WITH COPYING PARTITIONED INNODB TABLES FROM LINUX TO WINDOWS

This problem was already fixed in mysql-trunk as part of bug #11755924.  I am 
backporting the fix to mysql-5.1.  

merge of Nirbhay's AIX compilation fix for 5.1.61

Fixing the 5.5 part (the 5.6 part will go in a separate commit soon).

Problem:
  Item_direct_ref::get_date() incorrectly calculated its "null_value",
  which made UNIX_TIMESTAMP(view_column) incorrectly return NULL
  for a NOT NULL view_column.

Fix:
  Make Item_direct_ref::get_date() calculate null_value
  in the similar way with the other methods 
  (val_real,val_str,val_int,val_decimal):
  copy null_value from the referenced Item.

mysqldump in xml mode did not dump routines, events or

This patch fixes this issue by fixing the if conditions
that disallowed the dump of above mentioned objects in
xml mode, and added the required code to enable dump
in xml format.

  for xml and further added the relevant code at places to produce
  the dump in xml format.
