the test for bug 37956 isn't relevant anymore.
The query there 'select point(?,?)' doesn't produce an error.

                       
Killing the insert-select statement corrupts the MyISAM table only
when the destination table is empty and when it has indexes. When 
we bulk insert huge data and if the destination table is empty we 
disable the indexes for fast inserts, data is then inserted and 
indexes are re-enabled after bulk_insert operation
                        
Killing the query, aborts the repair table operation during enable
indexes phase leading to table corruption.
                      
We now truncate the table when we detect that enable indexes is
killed for bulk insert query.As we have an empty table before the 
operation, we can fix by truncating the table.

      
A bug in the initialization of key segment information made it point
to the wrong bit, since a bit index was used when its int value
was needed. This lead to misinterpretation of bit columns
read from MyISAM record format when a NULL bit pushed them over
a byte boundary.
Fixed by using the int value of the bit instead.

key_buffer_size.

The cause of corruption was number overflow when multiplying 
two ulong values, number of used keycache blocks with size
of a single block. The result of multiplication exceeded ulong 
range (4G) and this lead to incorrectly calculated  buffer offset
in the key cache.

The fix is to use size_t for multiplication result.

This patch also fixes pointless cast in safemalloc 
(size of allocated block to uint), that creates lot of false
alarm warnings when using big keycache (> 4GB) in debug mode.

The storage engine was not correctly handling the case in 
which rnd_pos is executed for a handler without a preceding
rnd_next or index read operation. As a result, an unitialized
file handle was sometimes being passed to the QMY_READ API.

The fix clears the rrnAssocHandle at the beginning of each
read operation and then checks to see whether it has been
set to a valid handle value before attempting to use it
in rnd_pos. If rrnAssocHandle has not been set by a previous
read operation, rnd_pos instead falls back to the use of the
currently active handle.

      Several 5.0 tests do not pass MTR's --check option (moved from Bug 42308)

                  (moved from Bug 42308)

Details:
- insert_update
  Add DROP TABLE which was missing, error numbers -> names
- varbinary
  Add DROP TABLE which was missing
- sp_trans_log
  Add missing DROP function, improved formatting

      
Fixed a number of typos, and made punctuation and
capitalization more consistent in documentation
and help.

   the Point() and Linestring() functions create WKB representation of an
   object instead of an real geometry object.
   That produced bugs when these were inserted into tables.

   GIS tests fixed accordingly.

Bug #40925: Equality propagation takes non indexed attribute

Query execution plans and execution time of queries like

  select a, b, c from t1
    where a > '2008-11-21' and b = a limit 10

depended on the order of equality operator parameters:
"b = a" and "a = b" are not same. 


An equality propagation algorithm has been fixed:
the substitute_for_best_equal_field function should not
substitute a field for an equal field if both fields belong
to the same table.

The fix is to disable result log as we need to
test valgrind error only.

Respectively, replaced "--exec diff" by "--diff_files" which is a mysqltest command to run a
non-operating system specific diff. Removed the file rpl_000015-slave.sh as it is not
necessary in the new MTR.

Turned off autocommit at the start of this test per Innobase recommendation.
Noted significant reduction in run time for this test w/ a minor increase in other tests' run-times.

buf_page_get_gen() returns NULL.  The page may have been evicted

NULL merge fix for BUG#43660 into 5.1 as the fix for this bug
is already applied in 5.1

                   for indexes of InnoDB table

Fixes by replacing the PRNG that is used to pick random pages with a 
better one. 

Also adds a configuration option "innodb_use_legacy_cardinality_algorithm"
to enable the fix only when the option is set.

This patch is from http://bugs.mysql.com/file.php?id=11789

Entry for build-vs9.bat and build-vs9_x64.bat was missing in
win/Makefile.am. Added the entries to fix the problem.

          specifc command

Replaced "--exec rm" by "remove_file" which is a mysqltest command to
erase a file.
