timeout
            
In STMT and MIXED modes, a statement that changes both non-transactional and
transactional tables must be written to the binary log whenever there are
changes to non-transactional tables. This means that the statement gets into the
binary log even when the changes to the transactional tables fail. In particular
, in the presence of a failure such statement is annotated with the error number
and wrapped in a begin/rollback. On the slave, while applying the statement, it
is expected the same failure and the rollback prevents the transactional changes
to be persisted.
            
Unfortunately, statements that fail due to concurrency issues (e.g. deadlocks,
timeouts) are logged in the same way causing the slave to stop as the statements
are applied sequentially by the SQL Thread. To fix this bug, we automatically
ignore concurrency failures on the slave. Specifically, the following failures
are ignored: ER_LOCK_WAIT_TIMEOUT, ER_LOCK_DEADLOCK and ER_XA_RBDEADLOCK.

          server

If the server connection was lost during repeated status commands,
the client would fail to detect this and the client output would be inconsistent.

This patch fixes this issue by making sure that the server is online
before the client attempts to execute the status command.


client/mysql.cc:
  * Replace variable "connected" with a call to mysql_real_query_for_lazy()
    will attempt to reconnect to server on if there is a failure.

The crash happend because for views which are joins
we have table_list->table == 0 and 
table_list->table->'any method' call leads to crash.
The fix is to perform table_list->table->file->extra()
method for all tables belonging to view.

sql/sql_table.cc:
  We should skip error sending then we should return

  The fix is to enable message storing into error message
  list for 'drop table' command(only for error case).

Using DECIMAL constants with more than 65 digits in CREATE 
TABLE ... SELECT led to bogus errors in release builds or 
assertion failures in debug builds. 
 
The problem was in inconsistency in how DECIMAL constants and 
fields are handled internally. We allow arbitrarily long 
DECIMAL constants, whereas DECIMAL(M,D) columns are limited to 
M<=65 and D<=30. my_decimal_precision_to_length() was used in 
both Item and Field code and truncated precision to 
DECIMAL_MAX_PRECISION when calculating value length without 
adjusting precision and decimals. As a result, a DECIMAL 
constant with more than 65 digits ended up having length less 
than precision or decimals which led to assertion failures. 
 
Fixed by modifying my_decimal_precision_to_length() so that 
precision is truncated to DECIMAL_MAX_PRECISION only for Field 
object which is indicated by the new 'truncate' parameter. 
 
Another inconsistency fixed by this patch is how DECIMAL 
constants and expressions are handled for CREATE ... SELECT. 
create_tmp_field_from_item() (which is used for constants) was 
changed as a part of the bugfix for bug #24907 to handle long 
DECIMAL constants gracefully. Item_func::tmp_table_field() 
(which is used for expressions) on the other hand was still 
using a simplistic approach when creating a Field_new_decimal 
from a DECIMAL expression.

contains ONLY_FULL_GROUP_BY

The partitioning code needs to issue a Item::fix_fields()
on the partitioning expression in order to prepare 
it for being evaluated.
It does this by creating a special table and a table list 
for the scope of the partitioning expression.
But when checking ONLY_FULL_GROUP_BY the 
Item_field::fix_fields() was relying that there always be
cached_table set and was trying to use it to get the 
select_lex of the SELECT the field's table is in.
But the cached_table was not set by the partitioning code
that creates the artificial TABLE_LIST used to resolve the
partitioning expression and this resulted in a crash.
 
Fixed by rectifying the following errors :
1. Item_field::fix_fields() : the code that check for 
ONLY_FULL_GROUP_BY relies on having tables with 
cacheable_table set. This is mostly true, the only 
two exceptions being the partitioning context table
and the trigger context table.
Fixed by taking the current parsing context if no pointer
to the TABLE_LIST instance is present in the cached_table.

2. fix_fields_part_func() : 

2a. The code that adds the table being created to the 
scope for the partitioning expression is mostly a copy 
of the add_table_to_list and friends with one exception :
it was not marking the table as cacheable (something that
normal add_table_to_list is doing). This caused the 
problem in the check for ONLY_FULL_GROUP_BY in 
Item_field::fix_fields() to appear.
Fixed by setting the correct members to make the table
cacheable.
The ideal structural fix for this is to use a unified 
interface for adding a table to a table list 
(add_table_to_list?) : noted in a TODO comment

2b. The Item::fix_fields() was called with a NULL destination
pointer. This causes uninitalized memory reads in the 
overloaded ::fix_fields() function (namely 
Item_field::fix_fields()) as it expects a non-zero pointer 
there. Fixed by passing the source pointer similarly to how 
it's done in JOIN::prepare().

Creating an IBMDB2I table with the macce character set
is successful, but any attempt to insert data into the
table was failing.

This was happening because the character set name "macce"
is not a valid iconv descriptor for IBM i PASE. This patch
adds an override to convertTextDesc to use the equivalent
valid iconv descriptor "IBM-1282" instead.

without proper formatting
      
The problem is that a suitably crafted database identifier
supplied to COM_CREATE_DB or COM_DROP_DB can cause a SIGSEGV,
and thereby a denial of service. The database name is printed
to the log without using a format string, so potential
attackers can control the behavior of my_b_vprintf() by
supplying their own format string. A CREATE or DROP privilege
would be required.
      
This patch supplies a format string to the printing of the
database name. A test case is added to mysql_client_test.


sql/sql_parse.cc:
  Added format strings.

After applying Innodb snapshot 5.1-ss5282, build was broken
because of missing header file. 

Adding the header file to Makefile.am after informing the

Add new header to Makefile.am so it gets bundled.
