Let
  - T be a transactional table and N non-transactional table.
  - B be begin, C commit and R rollback.
  - M be a mixed statement, i.e. a statement that updates both T and N.
  - M* be a mixed statement that fails while updating either T or N.

This patch restore the behavior presented in 5.1.37 for rows either produced in
the RBR or MIXED modes, when a M* statement that happened early in a transaction
had their changes written to the binary log outside the boundaries of the
transaction and wrapped in a BEGIN/ROLLBACK. This was done to keep the slave
consistent with with the master as the rollback would keep the changes on N and
undo them on T. In particular, we do what follows:

  . B M* T C would log - B M* R B T C.

Note that, we are not preserving history from the master as we are introducing a
rollback that never happened. However, this seems to be more acceptable than
making the slave diverge. We do not fix the following case:

  . B T M* C would log B T M* C.

The slave will diverge as the changes on T tables that originated from the M
statement are rolled back on the master but not on the slave. Unfortunately, we
cannot simply rollback the transaction as this would undo any uncommitted
changes on T tables.

SBR is not considered in this patch because a failing statement is written to
the binary along with the error code and a slave executes and then rolls back
the statement when it has an associated error code, thus undoing the effects
on T. In RBR and MBR, a full-fledged fix will be pushed after the WL 2687.

All statements executed by mysql_upgrade are binlogged and then are replicated to slave.
This will result in some errors. The report of this bug has demonstrated some examples.

Master and slave should be upgraded separately. All statements executed by
mysql_upgrade will not be binlogged. 
--write-binlog and --skip-write-binlog options are added into mysql_upgrade. 
These options control whether sql statements are binlogged or not. 

      
In RBR, 'DROP TEMPORARY TABLE IF EXISTS...' statement is binlogged when the table
does not exist.
      
In fact, 'DROP TEMPORARY TABLE ...' statement should never be binlogged in RBR
no matter if the table exists or not. 
This patch addresses this by checking whether we are dropping a
temporary table or not, when building the custom drop statement.

HA_ERR_WRONG_INDEX
      
In RBR, disabling keys on slave table will break replication when
updating or deleting a record. When the slave thread tries to
find the row, by searching in the storage engine, it checks
whether the table has a key or not. If it has one, then the slave
thread uses it to search the record.
      
Nonetheless, the slave only checks whether the key exists or not,
it does not verify if it is active. Should the key be
disabled (eg, DBA has issued an ALTER TABLE ... DISABLE KEYS)
then it will result in error: HA_ERR_WRONG_INDEX.
      
This patch addresses this issue by making the slave thread also
check whether the key is active or not before actually using it.

The failure is not reproduced on 5.1, so enable the 'rpl_cross_version' test.

mysql-test/suite/rpl/t/disabled.def:
  Got rid of the line for enabling 'rpl_cross_version' test.

Network error happened here, but it can be caused by CR_CONNECTION_ERROR, 
CR_CONN_HOST_ERROR, CR_SERVER_GONE_ERROR, CR_SERVER_LOST, ER_CON_COUNT_ERROR, 
and ER_SERVER_SHUTDOWN. We just check CR_SERVER_LOST here, so the test fails.

To fix the problem, check all errors that can be cause by the master shutdown.

mysql-test/extra/rpl_tests/rpl_get_master_version_and_clock.test:
  Added a 'if' sentence to check all errors that can be cause by the master shutdown.

when compiled with Sun Studio compiler).

The thing is that Sun Studio compiler calls destructor of stack
objects when pthread_exit() is called. That triggered an assertion
in DBUG_ENTER()/DBUG_RETURN() validation logic (if DBUG_ENTER() is
used in the beginning of function, all returns should be replaced
by DBUG_RETURN/DBUG_VOID_RETURN macros).

A fix is to explicitly use DBUG_LEAVE macro.

With the fix for BUG#46760, we correctly flag the presence of row_type 
only when it's actually changed and enables the FAST ALTER TABLE which was
disabled with the BUG#39200.

So the changes made by BUG#46760 makes MySQL data dictionaries to be out of 
sync but they are handled already by InnoDB with this BUG#44030.

The test was originally written to handle this but we requested Innodb to
update the test as the data dictionaries were in sync after the fix for 
BUG#39200.

Adjusting the innodb-autoinc testcase as mentioned in the comments.

  Adjust the innodb-autoinc testcase as the patch for BUG#46760 enables the 
  FAST ALTER TABLE and makes the data dictonaries go out of sync. This is 
  expected in the testcase.

The problem was that checksum of GEOMETRY type used memory addresses
in the computation, making it un-repeatable thus useless.

sql/sql_table.cc:
  Type GEOMETRY is implemented on top of type BLOB, so, just like for BLOB,
  its 'field' contains pointers which it does not make sense to include in
  the checksum; it rather has to be converted to a string and then we can
  compute the checksum.

      
Despite copying the value of the old table's row type
we don't always have to mark row type as being specified.
Innodb uses this to check if it can do fast ALTER TABLE
or not.
Fixed by correctly flagging the presence of row_type 
only when it's actually changed.
Added a test case for 39200.

           But there is no Last_IO_Error reported.

On the master, if a binary log event is larger than max_allowed_packet,
ER_MASTER_FATAL_ERROR_READING_BINLOG and the specific reason of this error is
sent to a slave when it requests a dump from the master, thus leading
the I/O thread to stop.

On a slave, the I/O thread stops when receiving a packet larger than max_allowed_packet.

In both cases, however, there was no Last_IO_Error reported.

This patch adds code to report the Last_IO_Error and exact reason before stopping the
I/O thread and also reports the case the out memory pops up while
handling packets from the master.


sql/sql_repl.cc:
  The master send the Specific reasons instead of "error reading log entry" to the slave which is requesting a dump.

 "insert into.. select * from"

When inserting into a partitioned table using 'insert into
<target> select * from <src>', read_buffer_size bytes of memory
are allocated for each partition in the target table.

This resulted in large memory consumption when the number of
partitions are high.

This patch introduces a new method which tries to estimate the
buffer size required for each partition and limits the maximum
buffer size used to maximum of 10 * read_buffer_size, 
11 * read_buffer_size in case of monotonic partition functions.

sql/ha_partition.cc:
  Introduced a method ha_partition::estimate_read_buffer_size
  to estimate buffer size required for each partition. 
  Method ha_partition::start_part_bulk_insert updated
  to update the read_buffer_size before calling bulk upload
  in storage engines.
  Added thd in ha_partition::start_part_bulk_insert method signature.
sql/ha_partition.h:
  Introduced a method ha_partition::estimate_read_buffer_size.
