306ed65302 unix_timestamp() and from_unixtime() supports microseconds.
unix_timestamp() and time_to_sec() are hybrid items,
  returning integer or double depending on the argument.

3b7f044534 Bug#11766126 59166: ANOTHER DATETIME VALGRIND UNINITIALIZED WARNING
Valgrind warning happens because null values check happens too late
in Item_func_month::val_str(after result string calculation).The fix
is to check null value before result string calculation.

8b7fd8f577 lp:731124 Loss of precision on DISTINCT
many changes:
* NOT_FIXED_DEC now create hires fields, not old ones.

* Item_func_coalesce calculates decimals for temporal types
* no precision for TIME/DATETIME in CAST means 0, not NOT_FIXED_DEC
* addtime/timediff calculate decimals from arguments (not NOT_FIXED_DEC)

Bug#57071: EXTRACT(WEEK from date_col) cannot be allowed as partitioning function

There were functions allowed as partitioning functions

Solution was to check that the arguments of date and time functions

20d704978d Bug #52160: crash and inconsistent results when grouping
by a function and column

The bugreport reveals two different bugs about grouping
on a function:

1) grouping by the TIME_TO_SEC function result caused
   a server crash or wrong results and
2) grouping by the function returning a blob caused
   an unexpected "Duplicate entry" error and wrong
   result.

Details for the 1st bug:

TIME_TO_SEC() returns NULL if its argument is invalid (empty
string for example). Thus its nullability depends not only
on the nullability of its arguments but also on their values.
Fixed by (overoptimistically) setting TIME_TO_SEC() to be
nullable despite the nullability of its arguments.

Details for the 2nd bug:

The server is unable to create indices on blobs without
explicit blob key part length. However, this fact was
ignored for blob function result fields of GROUP BY
intermediate tables.
Fixed by disabling GROUP BY index creation for blob
function result fields like regular blob fields.

Fixed a number of memory leaks discovered by valgrind.

dbug/dbug.c:
  This is actually an addendum to the fix for bug #52629:
  
  - there is no point in limiting the fix to just global

  that FreeState() does not deal with unitialized data later.

  used as a temporary storage in Item_extract::val_int().
sql/item_timefunc.h:
  Removed 'value' from the Item_extract class definition.
sql/sql_load.cc:
  - we may need to deallocate 'buffer' even when 'error' is
    non-zero in some cases, since 'error' is public, and there is
    external code modifying it.
  - assign NULL to buffer when deallocating it so that we don't
    do it twice in the destructor
  - there is no point in changing 'error' in the destructor.

8b25c0e4dc Bug #55565: debug assertion when ordering by expressions with user
variable assignments

The assert() that is firing is checking if expressions that can't be
null return a NULL when evaluated.
MAKEDATE() function can return NULL if the second argument is 
less then or equal to 0. Thus its nullability depends not only on 
the nullability of its arguments but also on their values.
Fixed by (overoptimistically) setting MAKEDATE() to be nullable 
despite the nullability of its arguments.
Test added.
Had to update one test result to reflect the metadata change.

c08e6c8867 Bug #42849: innodb crash with varying time_zone on partitioned
timestamp primary key 
 
Since TIMESTAMP values are adjusted by the current time zone  
settings in both numeric and string contexts, using any 
expressions involving TIMESTAMP values as a  
(sub)partitioning function leads to undeterministic behavior of  
partitioned tables. The effect may vary depending on a storage  
engine, it can be either incorrect data being retrieved or  
stored, or an assertion failure. The root cause of this is the  
fact that the calculated partition ID may differ from a  
previously calculated ID for the same data due to timezone  
adjustments of the partitioning expression value. 
 
Fixed by disabling any expressions involving TIMESTAMP values  
to be used in partitioning functions with the follwing two 
exceptions: 
 
1. Creating or altering into a partitioned table that violates 
the above rule is not allowed, but opening existing such tables 
results in a warning rather than an error so that such tables 
could be fixed. 
 
2. UNIX_TIMESTAMP() is the only way to get a 
timezone-independent value from a TIMESTAMP column, because it 
returns the internal representation (a time_t value) of a 
TIMESTAMP argument verbatim. So UNIX_TIMESTAMP(timestamp_column)
is allowed and should be used to fix existing tables if one 
wants to use TIMESTAMP columns with partitioning.

d66dc23065 Bug#42525: TIMEDIFF function

class Item_str_timefunc as per comments/docs,
but didn't add a method for that. And the
default just wasn't good enough for some
cases.

Changeset adds dedicated val_int() to class.

d096079d33 Bug#37553: MySql Error Compare TimeDiff & Time
We pretended that TIMEDIFF() would always return positive results;
this gave strange results in comparisons of the TIMEDIFF(low,hi)<TIME(0)
type that rendered a negative result, but still gave false in comparison.
We also inadvertantly dropped the sign when converting times to
decimal.

CAST(time AS DECIMAL) handles signs of the times correctly.
TIMEDIFF() marked up as signed. Time/date comparison code switched to
signed for clarity.

a3e83048a3 Fix for Bug#30217: Views: changes in metadata behaviour
between 5.0 and 5.1.
  
The problem was that in the patch for Bug#11986 it was decided
to store original query in UTF8 encoding for the INFORMATION_SCHEMA.
This approach however turned out to be quite difficult to implement
properly. The main problem is to preserve the same IS-output after
dump/restore.
  
So, the fix is to rollback to the previous functionality, but also
to fix it to support multi-character-set-queries properly. The idea
is to generate INFORMATION_SCHEMA-query from the item-tree after
parsing view declaration. The IS-query should:
  - be completely in UTF8;
  - not contain character set introducers.
  
For more information, see WL4052.

ae4141ed75 Bug#31160: MAKETIME() crashes server when returning NULL in ORDER BY using filesort
Even though it returns NULL, the MAKETIME function did not have this property set,
causing a failed assertion (designed to catch exactly this).
Fixed by setting the nullability property of MAKETIME().

1a5f13a12c Fix for bug #31249: Assertion `!table || (!table->write_set ||
bitmap_is_set(table->write_set, fiel

Problem: creating a temporary table we allocate the group buffer if needed
followed by table bitmaps (see create_tmp_table()). Reserving less memory for 
the group buffer than actually needed (used) for values retrieval may lead 
to overlapping with followed bitmaps in the memory pool that in turn leads 
to unpredictable consequences.

As we use Item->max_length sometimes to calculate group buffer size,
it must be set to proper value. In this particular case 
Item_datetime_typecast::max_length is too small.

Another problem is that we use max_length to calculate the group buffer
key length for items represented as DATE/TIME fields which is superfluous.

Fix: set Item_datetime_typecast::max_length properly,
accurately calculate the group buffer key length for items 
represented as DATE/TIME fields in the buffer.

  Fix for bug #31249: Assertion `!table || (!table->write_set ||

    - the group buffer key length for items represented as 
  DATE/TIME fields in the buffer should be calculated using
  the maximum pack length of such fields (== 8), using 
  max_length here is redundant.
