Install procedure does not copy *.inc files located under the mysql-test/t directory.
Therefore, this patch moves the rpl_trigger.inc to the mysql-test/include directory.

The test case fails sporadically on Windows while trying to overwrite an unused
binary log. The problem stems from the fact that MySQL on Windows does not
immediately unlock/release a file while the process that opened and closed it is
still running. In BUG 38603, this issue was circumvented by stopping the MySQL
process, copying the file and then restarting the MySQL process. 

Unfortunately, such facilities are not available in the 5.0.  Other approaches
such as stopping the slave and issuing change master do not work because the relay
log file and index are not closed when a slave is stopped. So to fix the problem,
we simply don't run on windows the part of the test that was failing.

- Define and pass compile time path variables as pre-processor definitions to 
  mimic the makefile build.
- Set new CMake version and policy requirements explicitly.
- Changed DATADIR to MYSQL_DATADIR to avoid conflicting definition in 
  Platform SDK header ObjIdl.h which also defines DATADIR.

correctly if the compiler optimizes too clever.

This has happaned on HP-UX 11.23 (IA64) at optimization
level "+O2", causing bug#42213:
   Check for "stack overrun" doesn't work, server crashes

Fix it by adding a pragma that prevents this optimization.
As a result, it should be safe to use "+O2" on this platform
(unless there is some other, optimizer-related, bug which
is just currently masked because we use resudec optimization).

            compression 
 
Since uint3korr() may read 4 bytes depending on build flags and 
platform, allocate 1 extra "safety" byte in the network buffer 
for cases when uint3korr() in my_real_read() is called to read
last 3 bytes in the buffer. 
 
It is practically hard to construct a reliable and reasonably 
small test case for this bug as that would require constructing 
input stream such that a certain sequence of bytes in a 
compressed packet happens to be the last 3 bytes of the network 
buffer. 

The maximum value of the max_join_size variable is set by converting
a signed type (long int) with negative value (-1) to a wider unsigned
type (unsigned long long), which yields the largest possible value of
the wider unsigned type -- as per the language conversion rules. But,
depending on build options, the type of the max_join_size might be a
shorter type (ha_rows - unsigned long) which causes the warning to be
thrown once the large value is truncated to fit.

The solution is to ensure that the maximum value of the variable is
always set to the maximum value of integer type of max_join_size.

Furthermore, it would be interesting to always have a fixed type for
this variable, but this would incur in a change of behavior which is
not acceptable for a GA version. See Bug#35346.

Post-merge fix: test case could fail due to a conversion of the
max_join_size value to a integer. Fixed by preserving the value
as a string for comparison purposes.

            procedures causes crashes!

The problem of that bugreport was mostly fixed by the
patch for bug 38691.
However, attached test case focused on another crash or
valgrind warning problem: SHOW PROCESSLIST query accesses
freed memory of SP instruction that run in a parallel
connection.

Changes of thd->query/thd->query_length in dangerous
places have been guarded with the per-thread
LOCK_thd_data mutex (the THD::LOCK_delete mutex has been
renamed to THD::LOCK_thd_data).

In create_myisam_from_heap() mark all errors as fatal except 
HA_ERR_RECORD_FILE_FULL for a HEAP table.

Not doing so could lead to problems, e.g. in a case when a
temporary MyISAM table gets overrun due to its MAX_ROWS limit
while executing INSERT/REPLACE IGNORE ... SELECT. 
The SELECT execution was aborted, but the error was 
converted to a warning due to IGNORE clause, so neither 'ok' 
nor 'error' packet could be sent back to the client. This 
condition led to hanging client when using 5.0 server, or 
assertion failure in 5.1.

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.

into 5.0-build.

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.

                    it returns misleading 'table is full'

Innodb returns a misleading error message "table is full" 
when the number of active concurrent transactions is greater
than 1024.

Fixed by adding errorcode "ER_TOO_MANY_CONCURRENT_TRXS" to the
error codes. Innodb should return HA_TOO_MANY_CONCURRENT_TRXS
to mysql which is then mapped to ER_TOO_MANY_CONCURRENT_TRXS


Note: testcase is not written as this was reproducible only by
      changing innodb code.

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.

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.

  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.
