It is not possible to prevent the server from starting if a mandatory
built-in plugin fails to start. This can in some cases lead to data
corruption when the old table name space suddenly is used by a different
storage engine.

A boolean command line option in the form of --foobar is automatically
created for every existing plugin "foobar". By changing this command line
option from a boolean to a tristate { OFF, ON, FORCE } it is possible to
specify the plugin loading policy for each plugin.

The behavior is specified as follows:
   OFF   = Disable the plugin and start the server
   ON    = Enable the plugin and start the server even if an error occurrs
           during plugin initialization.
   FORCE = Enable the plugin but don't start the server if an error occurrs
           during plugin initialization.

      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.

is pushed along with BUG#43309.

Forgot to add BUG#4229 in the first paragraph in the commit

buf_page_get_gen() returns NULL.  The page may have been evicted
from the buffer pool between buf_page_peek_if_search_hashed() and

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.

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

init 'wc' variable

replaced String->c_ptr() with String->c_ptr_safe()

The warning happens because string argument is not zero ended.
The fix is to add new parameter 'length' to SQL_CRYPT() and
use ptr() instead of c_ptr().

      
The rpl_binlog_corruption test case was inject failures, specifically,
incidents with invalid numbers to see if the replication was failing
gracefully. However, this test was causing the following warning message
in Valgrind: "Conditional jump or move depends on uninitialised value(s)"
      
The patch fixes the problem by correctly initializing the m_inicident 
number.

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.
