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

no conflicts

                  (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.

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.

branches/5.0: btr_search_drop_page_hash_when_freed(): Check if
buf_page_get_gen() returns NULL.  The page may have been evicted
from the buffer pool between buf_page_peek_if_search_hashed() and
buf_page_get_gen(), because the buffer pool mutex will be released
between these two calls. (Bug #42279)

                   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

QUERY statement
      
Commit 55629 applied to 5.0-bugteam and 5.1-bugteam: 
Check for thd->killed in CHECKSUM loop.

mysqldump.test is designed to run with concurrent inserts
disabled. It is disabling concurrent inserts at the very
beginning of the test case, and re-enables them at the
bottom of the test. But for some reason (likely incorrect
merge) we enable concurrent inserts in the middle of the test.

The problem is fixed by enabling concurrent inserts only
at the bottom of the test case.

  to wrong results
      
3 problems found with DES_ENCRYPT/DES_DECRYPT :

1. The max length was not calculated properly. Fixed in fix_length_and_dec()
2. DES_ENCRYPT had a side effect of sometimes reallocating and changing 
the value of its argument. Fixed by explicitly pre-allocating the necessary
space to pad the argument with trailing '*' (stars) when calculating the 
DES digest.
3. in DES_ENCRYPT the string buffer for the result value was not 
reallocated to the correct size and only string length was assigned to it. 
Fixed by making sure there's enough space to hold the result.

information schema tables are based on internal tmp tables which are removed
after each statement execution. So HANDLER comands can not be used with
information schema.

Streamlined how we increase the size of our test table.
The new method shows run time decreased by ~60%.
This is not a guarantee that we will not see test timeouts (the random failures noted in the bug),
but it should significantly reduce the chances of this occurring.

fixed message for 'help' command

routine does not exist 
      
There is an inconsistency with DROP DATABASE IF EXISTS, DROP TABLE IF
EXISTS and DROP VIEW IF EXISTS: those are binlogged even if the DB or
TABLE does not exist, whereas DROP PROCEDURE IF EXISTS does not. It
would be nice or at least consistent if DROP PROCEDURE/STATEMENT
worked the same too.
      
Fixed DROP PROCEDURE|FUNCTION IF EXISTS by adding a call to
mysql_bin_log.write in mysql_execute_command. Checked also if all 
documented "DROP (...) IF EXISTS" get binlogged.
      
NOTE: This is a 5.0 backport patch as requested by support.

The crash happens due to wrong 'digits' variable value(0),
'digits' can not be 0, so the fix is use 1 as min allowed value.

While printing the Max keyfile length 'llstr' call was used which 
was treating the max_key_file_length as negative.

Changing this to ullstr fixes the problem. 
myisamchk output will differ in 32 bit and 64 bit Operating systems 
so its not possible to have test case for this bug.

      
The test started failing following the push for BUG#41541.
Some of the algorithms access bytes beyond the input data
and this can affect up to one byte less than "word size"
which is BITS_SAVED / 8. 
      
Fixed by adding (BITS_SAVED / 8) -1 bytes to buffer size
(i.e. Memory Segment #2) to avoid accessing un-allocated data.

The problem is that a SELECT .. FOR UPDATE statement might open
a table and later wait for a impeding global read lock without
noticing whether it is holding a table that is being waited upon
the the flush phase of the process that took the global read
lock.

The same problem also affected the following statements:

LOCK TABLES .. WRITE
UPDATE .. SET (update and multi-table update)
TRUNCATE TABLE ..
LOAD DATA ..

The solution is to make the above statements wait for a impending
global read lock before opening the tables. If there is no
impending global read lock, the statement raises a temporary
protection against global read locks and progresses smoothly
towards completion.

Important notice: the patch does not try to address all possible
cases, only those which are common and can be fixed unintrusively
enough for 5.0.

Bug#32136: mysqld_multi --defaults-file not respected while using \
	--mysqld=mysqld_safe

Revert change that adds "--no-defaults" to mysqld_multi.

This closes Bug#43508 and re-opens Bug#32136.
