first row or fails with an error:
  ERROR 1022 (23000): Can't write; duplicate key in table ''

The server uses intermediate temporary table to store updated
row data.  The first column of this table contains rowid.
Current server implementation doesn't reset NULL flag of that
column even if the server fills a column with rowid.
To keep each rowid unique, there is an unique index.
An insertion into an unique index takes into account NULL
flag of key value and ignores real data if NULL flag is set.
So, insertion of actually different rowids may lead to two
kind of problems.  Visible effect of each of these problems
depends on an initial engine type of temporary table:

1. If multiupdate initially creates temporary table as
a MyISAM table (a table contains blob columns, and the
create_tmp_table function assumes, that this table is
large), it inserts only one single row and updates
only rows with one corresponding rowid. Other rows are
silently ignored. 

2. If multiupdate initially creates MEMORY temporary
table, fills it with data and reaches size limit for
MEMORY tables (max_heap_table_size), multiupdate
converts MEMORY table into MyISAM table and fails
with an error:
  ERROR 1022 (23000): Can't write; duplicate key in table ''


Multiupdate has been fixed to update the NULL flag of
temporary table rowid columns.

The REPAIR TABLE ... USE_FRM query silently corrupts data of tables
with old .FRM file version.
The mysql_upgrade client program or the REPAIR TABLE query (without
the USE_FRM clause) can't prevent this trouble, because in the
common case they don't upgrade .FRM file to compatible structure.

1. Evaluation of the REPAIR TABLE ... USE_FRM query has been
   modified to reject such tables with the message:
   "Failed repairing incompatible .FRM file".

2. REPAIR TABLE query (without USE_FRM clause) evaluation has been
   modified to upgrade .FRM files to current version.

3. CHECK TABLE ... FOR UPGRADE query evaluation has been modified
   to return error status when .FRM file has incompatible version.

4. mysql_upgrade and mysqlcheck client programs call CHECK TABLE
   FOR UPGRADE and REPAIR TABLE queries, so their behaviors have
   been changed too to upgrade .FRM files with incompatible
   version numbers.

For better conformance with standard, truncation procedure of CHAR columns
has been changed to ignore truncation of trailing whitespace characters
(note has been removed).

Finally, for columns with non-binary charsets:

1. CHAR(N) columns silently ignore trailing whitespace truncation;
2. VARCHAR and TEXT columns issue Note about truncation.

BLOBs and other columns with BINARY charset are unaffected.

We could allocate chunks larger than 4GB, but did our size-accounting in 32-bit
values. This could lead to spurious warnings, inaccurate accounting, and, in
theory, data loss.

larger than 4GB. For potential data loss, a re-alloc on such a buffer would be
necessary.

The bug is a regression introduced by the patch for bug32798.

The code in Item_func_group_concat::clear() relied on the 'distinct'
variable to check if 'unique_filter' was initialized. That, however,
is not always valid because Item_func_group_concat::setup() can do
shortcuts in some cases w/o initializing 'unique_filter'.

Fixed by checking the value of 'unique_filter' instead of 'distinct'
before dereferencing.

When a zero length is provided to the my_decimal_length_to_precision

Allocation and initialization of joined table list t1, t2... of

  1. JOIN::prepare initializes JOIN::table counter (actually a size
     of the JOIN::join_tab array) and sets it to a number of joined tables.
  
  2. The make_join_statistics function (when called from JOIN::optimize)
     allocates and fills the JOIN::join_tab array.
     However, when optimizing subselect has impossible (definite false)
     WHERE or HAVING clause, optimizer skips call to make_join_statistics
     and leaves JOIN::join_tab == NULL.
  
  3. subselect_single_select_engine::exec does traversal of the JOIN::join_tab
     array and the server dies because array is not allocated but array
     counter is greater than 0.
  
  The JOIN::optimize method has been modified to reset the JOIN::table
  counter to 0 in cause of impossible WHERE/HAVING clause.

Grouping or ordering of long values in not indexed BLOB/TEXT columns
with GBK or BIG5 charsets crashes the server.

MySQL server uses sorting (the filesort procedure) in the temporary
table to evaluate the GROUP BY clause in case of lack of suitable index.
That procedure takes into account only first @max_sort_length bytes
(system variable, usually 1024) of TEXT/BLOB sorting key string.
The my_strnxfrm_gbk and my_strnxfrm_big5 fill temporary keys
with data of whole blob length instead of @max_sort_length bytes
length. That buffer overrun has been fixed.
