Bug#39848 events_bugs fails sporadically on pushbuild
            (missing rows in table event_log)
     Details: Reimplement the subtest for BUG 28924
              - check if the number of rows within the table
                event_log changes but don't print rows
                because the number varies depending on
                load on testing box
              - shift DROP USER befor DROP EVENT
                = Subtest fits again to old bug
              - remove no more needed comments + variables
  Bug#39863 events_bugs fails sporadically on pushbuild 
            (extra processes in I_S.PROCESSLIST)
     Details: Abort with appropriate message to the protocol if
              release_lock() does not has the intended effect.
              This cannot prevent problems caused by the probably
              buggy release_lock() but it reveals if we had a
              problem in this area.
  Bug#39978 main.events_bugs does not clean up
     Detail: Restore global.event_scheduler = ON at end of test
  Bug#39569 events_bugs fails sporadically on pushbuild
            (should have failed with errno 1539)
     Detail: Set $wait_timeout to 4 instead of 2
- Fix two instabilities (result sets pulled from processlist in
  subtest for bug 16407) which were found during tests with high
  parallel I/O load
- Minor improvements of formatting
  Details:
  - Add comments
  - Remove tabs and trailing blanks
  - Add line breaks for better readability

a test on the bug page does not reveal the problem with the latest trees.

Adding the test to the rpl suite in order to monitor regression.


mysql-test/extra/rpl_tests/rpl_row_basic.test:
  a regression test for the bug#38230.
mysql-test/suite/rpl/r/rpl_row_basic_3innodb.result:
  results changed.

implicit command which isn't completed immediately.


mysql-test/r/status2.result:
  * Moved disconnect command to avoid race.
mysql-test/t/status2.test:
  * Moved disconnect command to avoid race.

A string buffers which were included in the 'view' data structure
were allocated on the stack, causing an invalid pointer when used
after the function returned.
The fix: use copy of values for view->md5 & view->queries

mysql-test/t/view.test:

The convert_constant_item function converts a constant to integer using
field for condition like 'field = a_constant'. When the convert_constant_item
is called for a subquery the outer select is already being executed, so
convert_constant_item saves field's value to prevent its corruption.
For EXPLAIN field's value isn't initialized thus when convert_constant_item
tries to restore saved value it fails assertion.
      
Now the convert_constant_item doesn't save/restore field's value
for EXPLAIN.


mysql-test/r/explain.result:
  Added a test case for the bug#37870.
mysql-test/t/explain.test:
  Added a test case for the bug#37870.
sql/item_cmpfunc.cc:
  Bug#37870: Usage of uninitialized value caused failed assertion.
  Now the convert_constant_item doesn't save/restore field's value
  for EXPLAIN.

The abi_check target instroduced as part of WL#4380 verifies
changes to mysql.h. mysql.h in turn includes mysql_version.h.
mysql_version.h is a file that is generated during the configure
phase. We must ensure that mysql_version.h is cleaned only during
distclean and not during clean.

include/Makefile.am:
  This file contains the following changes
  
  1) Moves the cleaning of mysql_version.h from the clean
     phase to the distclean phase.
  
  2) Removes mysql_version.h.in from noinst_HEADERS, this
     entry was reduntant since by virtue of inclusion of
     mysql_version.h mysql_version.h.in is already included.

1. Replace --sleep by wait_* primitive
2. Vertical output for SHOW SLAVE STATUS
3. Updated result file

Problem: mysqld doesn't detect that enum data must be reinserted performing
'ALTER TABLE' in some cases.

Fix: reinsert data altering an enum field if enum values are changed.

  is changing by 'ALTER TABLE'.

- Make send_row_on_empty_set() return FALSE when simplify_cond() has found out
  that HAVING is always FALSE

Visual Studio 2008 Express edition does not include message compiler mc.exe
It is not possible to build MySQL server if only VC2008 Express is installed,
because we use mc.exe to generate event log messages.

This patch removes the mc.exe dependency. Generated files message.h, 
message.rc and MSG00001.bin  are checked into source code repository.
Instructions on how to add or change messages are added to messages.mc

Added test case to check the default value of @@binlog_format.

mysql-test/t/binlog_format_basic.test:
  Added test case to verify the default binlog_format: it should be
  STATEMENT in 5.1 and MIXED in 6.0.

mysql-test/r/xa.result:
  Update test case result.
mysql-test/t/xa.test:
  Drop table used for test.
