The reason for the failure was a bug in an include file on debian that causes 'struct stat'
to have different sized depending on the environment.
This patch fixes so that we always include my_global.h or my_config.h before we include any other files.
Other things:
- Removed #include <my_global.h> in some include files; Better to always do this at the top level to have as few
"always-include-this-file-first' files as possible.
- Removed usage of some include files that where already included by my_global.h or by other files.

- Make log_slow_verbosity print "Priority_queue: (Yes|No)" into the slow query log.
(but we do not add a correspoding column to P_S.*statement* tables).
- Filesort has an optmization where it reads only columns that are
needed before the sorting is done.
- When ref(_or_null) is picked by the join optimizer, it may remove parts
of WHERE clause that are guaranteed to be true.
- However, if we use quick select, we must put all of the range columns into the
read set. Not doing so will may cause us to fail to detect the end of the range.
(assert added by MySQL verified that strnxfrm can only *increase*
the string length if from == to, and the latter is a random
decision made by individual items and String::realloc).
Fix it by avoiding the memcpy in the first place.

Don't call unlock_row() in case of errors
FROM SUBSELECT
ISSUE : In function find_all_keys.
If selected row do not satisfy condition
then we call unlock_row to release the locked
row. Suppose if we have subquery in condition
and we have an innodb error during its execution.
Then we should not call the unlock_row. If the error
is because of deadlock, innodb will rollback the
transaction. And calling unlock_row without
transaction is an invalid case hence an assertion
failure.
SOLUTION : We call unlock_row only if only there is no
error occurred previously.
The solution is back ported from 5.6
defect number 14226481

WITH SORT ABORTED LEAKS FILE DESCRIPTORS
ISSUE : IO_CACHE used for index_merge quick select
is freed only on successful retrieval of all rows
from index merge.
Suppose if there is a interrupt( or failure) to
this operation of row retrieval (let it be a
KILL_QUERY signal) then we are not freeing the IO_CACHE
resources allocated by index_merge quick select.
And hence temp file associated with it is also not closed.
This lead to a file descriptor leak.
SOLUTION : As part of file sort operation now we always
free the IO_CACHE allocated by index_merge quick select.
sql/filesort.cc:
In filesort function we try to free if any
IO_CACHE allocated by index_merge quick select
and if it is not yet freed.

Problem:-
We have created a table with UTF8_BIN collation.
In case, when in our query we have ORDER BY clause over a function
call we are getting result in incorrect order.
Note:the bug is not there in 5.5.
Analysis:
In 5.5, for UTF16_BIN, we have min and max multi-byte length is 2 and 4
respectively.In make_sortkey(),for 2 byte character character we are
assuming that the resultant length will be 2 byte/character. But when we
use my_strnxfrm_unicode_full_bin(), we store sorting weights using 3 bytes
per character.This result in truncated result.
Same thing happen for UTF8MB4, where we have 1 byte min multi-byte and
4 byte max multi-byte.We will accsume resultant data as 1 byte/character,
which result in truncated result.
Solution:-
use strnxfrm(means use of MY_CS_STRNXFRM macro) is used for sort, in
which the resultant length is not dependent on source length.

Description:
------------
There are 2 issues reported in the bug report,
1. One session running a "long" select, then, from the other
session, you kill that first one, while select is
running, and it receives that message "Server shutdown in
progress".
Reported Date: 02-Apr-2006
=> Looks like this isuse is already fixed in 2009 by the patch
pushed for bug28141.
2. Killing query which goes to filesort, logs error entries like:
120416 9:17:28 [ERROR] mysqld: Sort aborted: Server shutdown in
progress
120416 9:18:48 [ERROR] mysqld: Sort aborted: Server shutdown in
progress
120416 9:19:39 [ERROR] mysqld: Sort aborted: Server shutdown in
progress
Reported Date: 16-Apr-2012
=> This issue is introduced in 5.5+ versions. Fixing this issue
in this patch.
Analysis:
---------
In function "filesort()", on error we are logging error message.
To the error message, the message related THD::killed_errno is
also appeneded, if it is set.(THD::kill_errno value is obtained
by calling member function THD::killed_errno)
In the scenario mentioned in this bug report, when we kill the
connection, THD::kill_errno is set to the THD::KILL_CONNECTION.
Enum type THD::KILL_CONNECTION corressponds to value
ER_SERVER_SHUTDOWN. Because of this, "Server shutdown in ...." is
appended to the message logged.
Fix:
----
Modified code of "filesort()" function to append "KILL_QUERY"
status to error message when thread is killed and server
shutdown is not in progress.

includes:
* remove some remnants of "Bug#14521864: MYSQL 5.1 TO 5.5 BUGS PARTITIONING"
* introduce LOCK_share, now LOCK_ha_data is strictly for engines
* rea_create_table() always creates .par file (even in "frm-only" mode)
* fix a 5.6 bug, temp file leak on dummy ALTER TABLE
Cleanup: remove TIME_FUZZY_DATE.
Introduce TIME_FUZZY_DATES which means "very fuzzy, the resulting
value is only used for comparison. It can be invalid date, fine, as long as it can be
compared".
