Bug#17588348: INDEX MERGE USED ON PARTITIONED TABLE 
               CAN RETURN WRONG RESULT SET

PROBLEM
-------
In ha_partition::cmp_ref() we were only calling the 
underlying cmp_ref() of storage engine if the records
are in the same partiton,else we sort by partition and
returns the result.But the index merge intersect 
algorithm expects first to sort by row-id first and 
then by partition id.

FIX
---
Compare the refernces first using storage engine cmp_ref
and then if references are equal(only happens if 
non clustered index is used) then sort it by partition id.

Bug#17702677 WRONG INSTRUMENTATION INTERFACE FOR MYSQL_COND_TIMEDWAIT

The pthread_cond_timedwait(3P) api
uses a const struct timespec for parameter 3.

The instrumentation api for the same, mysql_cond_timedwait,
which expands to inline_mysql_cond_timedwait,
should also take a const parameter for the timespec.

This fix add the missing const to inline_mysql_cond_timedwait.
Bug#16736412: THE SERVER WAS CRASHED WHILE EXECUTING
"SHOW BINLOG EVENTS"

Problem:
========
mysql was crashed after executing "show binlog events in
'mysql-bin.000005' from 99", the crash happened randomly.

Analysis:
========
During construction of LOAD EVENT or NEW LOAD EVENT object
if the starting offset is provided as incorrect value then
all the object members that are retrieved from the offset
are also invalid.  Some times it will lead to out of bound
address offsets.  In the bug scenario, the file name is
extracrated from an invalid address and the same is fed to
strlen(fname) function. Passing invalid address to strlen
will lead to crash.

Fix:
===
Validate if the given offset falls within the event boundary
or not.
Bug#16691598 - ORDER BY LOWER(COLUMN) PRODUCES OUT-OF-ORDER RESULTS

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.

Bug #14057034 : WASTED CPU CYCLES IN MY_UTF8_UNI WHERE
                RESULTING MY_WC_T RESULT IS NOT USED
Issue         : handler functions my_ismbchar_utf8,
              my_well_formed_len_mb for charset utf8
              is calling unicode converion function
              to validate and to find the character
              length. Because of this, instructions
              which will convert the utf8 to unicode
              are executed for no use.
              A similar issue exist with charset utf8mb4
Solution      : reorganized the code such that character
              validation part of unicode conversion
              handler is extracted(duplicated) in to
              separate function. Hence
              my_ismbchar_utf8, my_well_formed_len_mb
              will call the new function which only
              validates and return the length of mb(utf8).
              A similar fix for charset utf8mb4.
Bug#17641586 INCORRECTLY PRINTED BINLOG DUMP INFORMATION

Problem:
When log_warnings is greater than 1, master prints binlog
dump thread information in mysqld.1.err file.
The information contains slave server id, binlog file and
binlog position. The slave server id is uint32 and the print
format was wrongly specifified (%d instead of %u).
Hence a server id which is more than 2 billion is getting
printed with a negative value.
Eg: Start binlog_dump to slave_server(-1340259414),
pos(mysql-bin.001663, 325187493)

Fix: Changed the uint32 format to %u.
Bug #17049656 : MYSQLD --LOCAL-SERVICE PARAMETER DOES NOT WORK

Problem: The "--local-install" service does not perform as expected for, at least,
         Windows.

Fix: A NULL pointer was dereferenced due to which there was crash.A check was introduced
     for NULL string before dereferencing it.No test cases written as it is a bug during 
     installation.
Bug #17708621 : EXCEEDING SORT_BUFFER_SIZE (FILE SORT) 
                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.

revid:mattias.jonsson@oracle.com-20131119103616-u6t82s8cpgp0q3ex

Use of uninitialized memory in the priority queue used for returning records
in sorted order.

It happens if no previous partition have returned a row since the
beginning of index_init + an index_read* call returned
HA_ERR_KEY_NOT_FOUND for all partitions (otherwise the record
buffer/priority queue would be initialized) + an index_next/prev
call where all partitions returns HA_ERR_END_OF_FILE.
Bug #17168602 MYSQL_PLUGIN REMOVES NON-DIRECTORY TYPE FILES 
              SPECIFIED WITH THE BASEDIR OPTION 

Description: The mysql_plugin client attempts to remove any
filename specified to the --basedir option. The problem is
that if the filename does not end with a slash, it will 
attempt to unlink it, which succeeds for files, but not for
directories.

Analysis: When we are starting mysql_plugin with basedir 
option and if we are giving path of a file as basedir, it 
deletes that file. It was because it uses a function 
my_delete which unlinks the file path given.

Fix:  As a fix we replace that line using another function 
my_free, which will only free the  pointer which is having 
that file path.
