The patch "mysql-chain-certs.patch" needs to be adapted
to code changes in "vio/viosslfactories.c" which were
done in MySQL 5.5.

Then, the patch can be re-enabled in the spec file.

Follow up patch to address the pb2 failures.

Follow up patch to address the pb2 failures.

A change to "vio/viosslfactories.c" in August, 2012,
broke a patch which is to be applied during the build
of ULN RPMs.
The patch file is
"packaging/rpm-uln/mysql-chain-certs.patch"

This change bypasses the problem by not trying to apply
the patch.

This is a regression and must be fixed, not bypassed.

Top level "SPECIFIC-ULN/" was inappropriate,
put the files to create RPMs for ULN into
"packaging/rpm-uln/".

               VARIABLES 

Analysis:
-------------
After executing the query, new value of the user defined
variables are set in the function "select_dumpvar::send_data".
"select_dumpvar::send_data" first calls function 
"Item_func_set_user_var::save_item_result()". This function
checks the nullness of the Item_field passed as parameter 
to it and saves it. The nullness of item is stored with 
arg[0]'s null_value flag. Then "select_dumpvar::send_data" calls
"Item_func_set_user_var::update()" which notices null 
result that was saved and calls "Item_func_set_user_var::
update_hash". But here null_value is not set and args[0]
is different from that given to function "Item_func_set_user_var::
set_item_result()". This causes "Item_func_set_user_var::
update_hash" function to believe that its getting non-null value.
"user_var_entry::length" set to 0 and hence "user_var_entry::value"
is made to point to extra_area allocated in "user_var_entry".
And "Item_func_set_user_var::update_hash" tries to write
at memory beyond extra_area for result type DECIMAL. Because of 
this invalid write issue is reported by Valgrind.

Before this bug was introduced, we avoided this problem by 
creating "Item_func_set_user_var" object with the same 
Item_field as arg[0] and as parameter to 
Item_func_set_user_var::save_item_result(). But now 
they are refering to different args[0]. Because of this
null_value flag set in parameter Item_field in function
"Item_func_set_user_var::save_item_result()" is not
reflected in "Item_func_set_user_var" object.

Fix:
------------
This issue is reported on versions 5.5.24. Issue does not exists
in 5.5.23, 5.1, 5.6 and trunk.

This issue was introduced by
revid:georgi.kodinov@oracle.com-20120309130449-82e3bs5v3et1x0ef (fix for
bug #12408412), which was pushed into 5.5 and later releases. This patch
has later been reversed in 5.6 and trunk by
revid:norvald.ryeng@oracle.com-20121010135242-xj34gg73h04hrmyh (fix for
bug #14664077). Backported this patch in 5.5 also to fix this issue.


sql/item_func.cc:
  here unsigned value is converted to signed value.
sql/item_func.h:
  last_insert_id() gives an auto_incremented value which can be
  positive only,so defined it as a unsigned longlong sets the
  unsigned_flag to 1.

Brief description: After insert some rows to MEMORY table with HASH key some 
rows can't be deleted in one step.    

Problem Analysis/solution: info->current_ptr will have the information about the
current hash pointer from where we can traverse to the list to get all the       
remaining tuples.
      
In hp_delete_key we are updating info->current_ptr with the last_pos based on       
the flag parameter(which is the keydef and last index are same). As part of the       
fix we are making it to zero only when the code flow reaches to the end of the       
function hp_delete_key() it means that the next record which has to get deleted       
will be at the starting of the list so, that in the next call to       
read record(heap_rnext()) will take line number 100 path instead of 102 path, 
please see the below code in file hp_rnext.c, function heap_rnext().
 99       else if (!info->current_ptr)              /* Deleted or first call */
100         pos= hp_search(info, keyinfo, info->lastkey, 0);
101       else  
102         pos= hp_search(info, keyinfo, info->lastkey, 1);

with that change the hp_search() will update the info->current_ptr with the 
record which needs to be deleted.

storage/heap/hp_delete.c:
  In heap_delete_key() function we are making info->current_ptr to 0 if 
  flag is enabled.

PROBLEM 
-------

optimize on partiton will recreate the whole table 
instead of just partition.

ANALYSIS
--------

At present innodb doesn't support optimize option ,so we do a rebuild of the 
whole table and then call analyze() on the table.Presently for any optimize()
option (on table or partition) we display the following info to the user 

"Table does not support optimize, doing recreate + analyze instead".

FIX
---

It was decided for GA versions(5.1 and 5.5) whenever the user tries to 
optimize a partition(s) we will will display the following info the user

"Table does not support optimize on partitions.
All partitions will be rebuilt and analyzed."

Earlier partitions were not analyzed.Now all partitions  will be analyzed.  

If the user wants to optimize the whole table ,we will display the
previous info to the user. i.e

"Table does not support optimize, doing recreate + analyze instead"

For 5.6+ versions we will raise a new bug to support optimize() options
in innodb.

Problem description:
mysql server crashes when we run repair table on currupted table.

Analysis:
The problem with this bug seem to be key_reflength out of bounds
(186 according to debugger). We read this value from meta-data
segment of .MYI file while doing mi_open().

If you look into _mi_kpointer() you can see that the upper limit
for key_reflength is 7.

Solution:
In mi_open() there is a line like:
  if (share->base.keystart > 65535 || share->base.rec_reflength > 8)
we should verify key_reflength here as well.

              DISABLE AND ENABLED DURING DDL OPERATION

PROBLEM: Same thread trying to acquire the same mutex
         second time leads to hang/server crash.
         While [un]installing audit_log plugin
         a thread acquires the LOCK_plugin mutex
         and after successful initialization tries
         to write in mysql.plugin table. It holds
         this mutex for a long time. If some how
         plugin table is corrupted then a write to 
         plugin table will throw an error, thread try
         to log this error in the audit_log plugin,
         doing so it tries to acquire the mutex
         again and results is server hang/crash.

SOLUTION: Releasing the LOCK_plugin mutex before
          writing in mysql.plugin table. We dont
          need to hold this mutex as thread already
          acquired a TL_WRITE lock on mysql.plugin
          table.

               main.mysqlbinlog_row_innodb are skipped by mtr

=== Problem ===

The following tests are wrongly placed in main suite and as a
result these are not run with proper binlog format combinations.
Some are always skipped by mtr.
1) mysqlbinlog_row_myisam
2) mysqlbinlog_row_innodb
3) mysqlbinlog_row.test
4) mysqlbinlog_row_trans.test
5) mysqlbinlog-cp932
6) mysqlbinlog2
7) mysqlbinlog_base64

=== Background ===

mtr runs the tests placed in main suite with binlog format=stmt.
Those that need to be tested against binlog format=row or mixed
or more than one binlog format and require only one mysql server
are placed in binlog suite. mtr runs tests in binlog suite with
all three binlog formats(stmt,row and mixed).

=== Fix ===


1) Moved the test listed in problem section above to binlog suite.
2) Added prefix "binlog_" to the name of each test case moved.
   Renamed the coresponding result files and option files accordingly. 


mysql-test/extra/binlog_tests/mysqlbinlog_row_engine.inc:
  include file for mysqlbinlog_row_myisam.test and 
  mysqlbinlog_row_myisam.test which are being moved to
  binlog suite.

  option file for mysqlbinlog-cp932.test which is being moved to
  binlog suite.
mysql-test/suite/binlog/t/binlog_mysqlbinlog-cp932.test:
  the test requires binlog format=stmt or mixed. Since, it was placed in
  main suite earlier, it was only run with binlog format=stmt, and hence
  this test was never run with binlog format=mixed.
mysql-test/suite/binlog/t/binlog_mysqlbinlog2.test:
  the test requires binlog format=stmt or mixed. Since, it was placed in
  main suite earlier, it was only run with binlog format=stmt, and hence
  this test was never run with binlog format=mixed.

  the test requires binlog format=row. Since, it was placed in main
  suite earlier, it was only run with binlog format=stmt, and hence

IN ALTER TABLE ... ADD UNIQUE KEY

A bogus debug assertion failure occurred when reporting a duplicate
key on a column prefix of a CHAR column.

This is a regression from Bug#14729221 IN-PLACE ALTER TABLE REPORTS ''
INSTEAD OF REAL DUPLICATE VALUE FOR PREFIX KEYS. The assertion is only
present when UNIV_DEBUG is defined (which it is in debug builds
starting from MySQL 5.5). It is a case of overasserting.

Fix approved by Inaam Rana on IM.
