  The fix refines the algorithm of generating DROPs for binlog.
  Temp tables with common pseudo_thread_id are clustered into one query.
  Consequently one replication event per pseudo_thread_id is generated.

(SELECT ... ORDER BY order_list1 [LIMIT n]) ORDER BY order_list2.

mysql-test/r/func_gconcat.result:
  Corrected test case for the bug#14169 to make it pass in --ps-protocol mode.

After a locking error the open table(s) were not fully
cleaned up for reuse. But they were put into the open table
cache even before the lock was tried. The next statement
reused the table(s) with a wrong lock type set up. This
tricked MyISAM into believing that it don't need to update
the table statistics. Hence CHECK TABLE reported a mismatch
of record count and table size.

Fortunately nothing worse has been detected yet. The effect
of the test case was that the insert worked on a read locked
table. (!)

I added a new function that clears the lock type from all
tables that were prepared for a lock. I call this function
when a lock failes.

No test case. One test would add 50 seconds to the
test suite. Another test requires file mode modifications.
I added a test script to the bug report. It contains three
cases for failing locks. All could reproduce a table
corruption. All are fixed by this patch.

This bug was not lock timeout specific.


sql/lock.cc:
  Bug#18544 - LOCK TABLES timeout causes MyISAM table corruption
  Resetting the lock type in the open table(s) lock data

The bug caused a reported index corruption in the cases when
key_cache_block_size was not a multiple of myisam_block_size,
e.g. when key_cache_block_size=1536 while myisam_block_size=1024.

Retrieving data from compressed MyISAM table which is bigger than 4G on 32-bit box
with mmap() support results in server crash.

mmap() accepts length of bytes to be mapped in second param, which is 32-bit
size_t. But we pass data_file_length, which is 64-bit my_off_t. As a result only
first data_file_length % 4G were mapped.

This fix adds additional condition for mmap() usage, that is use mmap() for
compressed table which size is no more than 4G on 32-bit platform.


myisam/mi_packrec.c:
  Use mmap() for compressed table which size is no more than 4G on 32-bit platform.

Conversion from int and real numbers to UCS2 didn't work fine: 
CONVERT(100, CHAR(50) UNICODE)
CONVERT(103.9, CHAR(50) UNICODE)

The problem appeared because numbers have binary charset, so,
simple charset recast binary->ucs2 was performed
instead of real conversion.

Fixed to make numbers pretend to be non-binary.

In a simple queries a result of the GROUP_CONCAT() function was always of 
varchar type.
But if length of GROUP_CONCAT() result is greater than 512 chars and temporary
table is used during select then the result is converted to blob, due to
policy to not to store fields longer than 512 chars in tmp table as varchar
fields.

In order to provide consistent behaviour, result of GROUP_CONCAT() now
will always be converted to blob if it is longer than 512 chars.
Item_func_group_concat::field_type() is modified accordingly.

  The unnamed constant 255 in the create_tmp_field() and create_tmp_field_from_item() functions now defined as the CONVERT_IF_BIGGER_TO_BLOB constant.
  The create_tmp_field() function now converts the Item_sum string result to a blob field based on its char length.
sql/item_sum.h:
  Fixed bug#14169: type of group_concat() result changed to blob if tmp_table was used
  To the Item_func_group_concat calls added the member function field_type() which returns the BLOB or VAR_STRING type based on the items length.
sql/item_func.cc:
  Fixed bug#14169: type of group_concat() result changed to blob if tmp_table was used
  In the Item_func::tmp_table_field() function the unnamed constant 255 is changed to the CONVERT_IF_BIGGER_TO_BLOB constant.
  The Item_func::tmp_table_field() function now measures the result length in chars rather than bytes when converting string result to a blob.
