my_error() was invoked in reset_slave()'s with purge_relay_logs()-failing branch
without passing sql_errno to it.

Fixed with setting sql_errno= ER_RELAY_LOG_FAIL in the purge_relay_logs()-failing branch.




sql/sql_repl.cc:
  set sql_errno= ER_RELAY_LOG_FAIL when purge_relay_logs() fails.

      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

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.


mysql-test/r/select.result:
  Added test case for bug #40925.

  Bug #40925: Equality propagation takes non indexed attribute
  
  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.

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.

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

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.

  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.
