format." warnings
      
Despite the fact that a statement would be filtered out from binlog, a
warning would still be thrown if it was issued with the LIMIT.
      
This patch addresses this issue by checking the filtering rules before
printing out the warning.


mysql-test/suite/binlog/t/binlog_stm_unsafe_warning-master.opt:
  Parameter to filter out database: "b42851".
mysql-test/suite/binlog/t/binlog_stm_unsafe_warning.test:
  Added a new test case.
sql/sql_class.cc:
  Added filtering rules check to condition used to decide whether to
  printout warning or not.

The problem is that the one phase commit function failed to
properly end a empty transaction. The solution is to ensure
that the transaction cleanup procedure is invoked even for
empty transactions.

mysql-test/r/xa.result:
  Add test case result for Bug#45548
mysql-test/t/xa.test:
  Add test case for Bug#45548
sql/handler.cc:
  Invoke transaction cleanup function whenever a transaction is ended.

The test case added failed sporadically on PB. This is due to the
fact that the user thread in some cases is waiting for slave IO
to stop and then check the error number. Thence, sometimes the
user thread would race for the error number with IO thread.

This post push fix addresses this by replacing the wait for slave
io to stop with a wait for slave io error (as it seems it was
added in 6.0 also after patch on which this is based was
pushed). This implied backporting wait_for_slave_io_error.inc
from 6.0 also.

such as quit and shutdown

Logging to slow log can produce an undetermined value for
Rows_examined in special cases. In debug mode this manifests
itself as any of the various marker values used to mark
uninitialized memory on various platforms.

If logging happens on a THD object that hasn't performed any
row reads (on this or any previous connections), the
THD::examined_row_count may be uninitialized. This patch adds
initialization for this attribute.

No automated test cases are added, as for this to be
meaningful, we need to ensure that we're using a THD
fulfilling the above conditions. This is hard to do in the
mysql-test-run framework. The patch has been verified
manually, however, by restarting mysqld and running the test
included with the bug report.

Because of a regression introduced by bug#19027 the option --enable-foobar
doesn't work anymore for any plugin 'foobar'. The reason is that plugin
names are tristate options variables with optional parameters and integer
values are not accepted. Since the 'enable' prefix attempts to assign '1'
to the option the operation fails.

This patch translates any number n assigned to a plugin variable of type ENUM
to be the corresponding enumerated item. As a side effect --enable-foobar and
--disable-foobar will also start working again.

mysys/my_getopt.c:
  * setval now accepts integer values for option variables of type ENUM.

The reason for the crash was rotate_relay_log (mi=0x0) did not verify
the passed value of active_mi.  There are more cases where active_mi
is supposed to be non-zero e.g change_master(), stop_slave(), and it's
reasonable to protect from a similar crash all of them with common
fixes.
            
Fixed with spliting end_slave() in slave threads release and slave
data clean-up parts (a new close_active_mi()). The new function is
invoked at the very end of close_connections() so that all users of
active_mi are proven to have left.

sql/mysqld.cc:
  added the 2nd part (data) of the slave's clean up.
sql/slave.cc:
  end_slave() is split in two part to release the slave threads and the remained
  resources separately.
  The new close_active_mi() should be called after all possible users ofactive_mi
  has left, i.e at the very end of close_connections().
sql/slave.h:
  interface to the new end_active_mi() function is added.

            queries if query was killed 
 
Since we rely on thd->is_error() to decide whether we should 
COMMIT or ROLLBACK after a query execution, check the query 
'killed' state and throw an error before calling 
ha_autocommit_or_rollback(), not after. 
 
The patch was tested manually. For reliable results, the test 
case would have to KILL QUERY while a DELETE/UPDATE query in 
another thread is still running. I don't see a way to achieve 
this kind of synchronization in our test suite (no debug_sync 
in 5.1).

sql/sql_parse.cc:

  COMMIT or ROLLBACK after query execution, check the query

Bug#44653: Server crash noticed when executing random queries with partitions.

When opening a table, it is imperative that the flag
TABLE::auto_increment_field_not_null be false. But if an error occured during
the creation of a table (e.g. the table exists already) with an auto_increment
column and a BEFORE trigger that used the INSERT ... SELECT construct, the
flag was not reset until after error checking. Thus if an error occured,
select_insert::send_data() returned immediately and it was not reset (see * in
pseudocode below).  Crash happened if the table was opened again. Fixed by
resetting the flag after error checking.

nested-loops_join():
  for each row in SELECT table {
    select_insert::send_data():
      if a values is supplied for AUTO_INCREMENT column
         table->auto_increment_field_not_null= TRUE
       else
         table->auto_increment_field_not_null= FALSE
       if (error)
         return 1; *
       if (table->auto_increment_field_not_null == FALSE)
         ...
       table->auto_increment_field_not_null == FALSE 
  }
<-- table returned to table cache and later retrieved by open_table: 
open_table():
  assert(table->auto_increment_field_not_null)
