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.

                               value from the index (PRIMARY)


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

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.

This is the fifth patch cleaning up more GCC warnings about
variables used before initialized using the new macro
UNINIT_VAR().

 "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.
  Added thd in ha_partition::start_part_bulk_insert method signature.

1. Fixes BUG#44030 - Error: (1500) Couldn't read the MAX(ID) autoinc value 
                     from the index (PRIMARY)

2. Disables the innodb-autoinc test for innodb plugin temporarily.
   The testcase for this bug has different result file for InnoDB plugin.
   Should add the testcase to Innodb suite with a different result file.

branches/5.1: When the InnoDB and MySQL data dictionaries go out of sync, before
the bug fix we would assert on missing autoinc columns. With this fix we allow
MySQL to open the table but set the next autoinc value for the column to the
MAX value. This effectively disables the next value generation. INSERTs will
fail with a generic AUTOINC failure. However, the user should be able to
read/dump the table, set the column values explicitly, use ALTER TABLE to
set the next autoinc value and/or sync the two data dictionaries to resume
normal operations.

Remove the word "Error" from the printout because the mysqltest suite

Adjust the failing innodb-autoinc test to conform to the latest behavior
of the MySQL code. The idea and the comment in innodb-autoinc.test come
from Sunny.

      
The test case rpl_do_grant fails sporadically on PB2 with "Access
denied for user 'create_rout_db'@'localhost' ...". Inspecting the
test case, one may find that if issues a GRANT on the master
connection and immediately after it creates two new connections
(one to the master and one to the slave) using the credentials
set with the GRANT.
      
Unfortunately, there is no synchronization between master and
slave after the grant and before the connections are
established. This can result in slave not having executed the
GRANT by the time the connection is attempted.
      
This patch fixes this by deploying a sync_slave_with_master
between the grant and the connections attempt.

      
The test case creates two temporary tables, then closes the
connection, waits for it to disconnect, then syncs the slave with
the master, checks for remaining opened temporary tables on
slave (which should be 0) and finally drops the used
database (mysqltest).
      
Unfortunately, sometimes, the test fails with one open table on
the slave. This seems to be caused by the fact that waiting for
the connection to be closed is not sufficient. The test needs to
wait for the DROP event to be logged and only then synchronize
the slave with the master and proceed with the check. This is
caused by the asynchronous nature of the disconnect wrt
binlogging of the DROP temporary table statement.
      
We fix this by deploying a call to wait_for_binlog_event.inc
on the test case, which makes execution to wait for the DROP
temp tables event before synchronizing master and slave.
