- Overwriting parent's charset_for_protocol() method,
becase we need to behave differenlty in VARCHAR and DATE/DATETYPE context.
- Adding ascii_buf for conversion.
- Adding val_str_ascii() prototype.
- Adding val_str() which uses newly added
Item_str_func::val_str_from_val_str_ascii(),
passing ascii_buf as a conversion buffer.

There were functions allowed as partitioning functions
that implicit allowed cast. That could result in unacceptable
behaviour.
Solution was to check that the arguments of date and time functions
have allowed types (field and date/datetime/time depending on function).

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.

The subtime function wasn't able to produce correct int representation of
its result. For constant expressions the Item_datetime_cache is used to
speedup evaluation and Item_datetime_cache expects underlying item to return
correct int representation of DATETIME value. These two factors combined led
to a wrong query result.
Now the Item_func_add_time has function val_datetime which performs the
calculation and saves result into given MYSQL_TIME struct, it also sets
null_value to appropriate value. val_int and val_str member functions
convert the result obtained from val_datetime to int or string respectively
and returns it.

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
variables, session ones are also affected.
- zero all fields when allocating a new 'state' structure so
that FreeState() does not deal with unitialized data later.
- add a check for a NULL pointer in DBUGCloseFile()

sql/item_timefunc.cc:
There is no point in declaring 'value' as a member of
Item_extract and dynamically allocating memory for it in
Item_extract::fix_length_and_dec(), since this string is only
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.
The Item_func_str_to_date class wasn't providing correct integer DATETIME
representation as expected. This led to wrong comparison result and didn't
allowed the STR_TO_DATE function to be used with indexes.
Also, STR_TO_DATE function was inconsisted on throwing warnings/errors.
Fixed now.
val_int and result_as_longlong methods were added to the Item_func_str_to_date
class.

on incorrect value.

Bug#56271: Wrong comparison result with STR_TO_DATE function

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.
This patch:
- Moves all definitions from the mysql_priv.h file into
header files for the component where the variable is
defined
- Creates header files if the component lacks one
- Eliminates all include directives from mysql_priv.h
- Eliminates all circular include cycles
- Rename time.cc to sql_time.cc
- Rename mysql_priv.h to sql_priv.h

Fixing tests
@ sql/field.cc
- Return str result using my_charset_numeric.
- Using real multi-byte aware str_to_XXX functions
to handle tricky charset values propely (e.g. UCS2)
@ sql/field.h
- Changing derivation of non-string field types to DERIVATION_NUMERIC.
- Changing binary() for numeric/datetime fields to always
return TRUE even if charset is not my_charset_bin. We need
this to keep ha_base_keytype() return HA_KEYTYPE_BINARY.
- Adding BINARY_FLAG into some fields, because it's not
being set automatically anymore with
"my_charset_bin to my_charset_numeric" change.
- Changing derivation for numeric/datetime datatypes to a weaker
value, to make "SELECT concat('string', field)" use character
set of the string literal for the result of the function.
@ sql/item.cc
- Implementing generic val_str_ascii().
- Using max_char_length() instead of direct read of max_length
to make "tricky" charsets like UCS2 work.
NOTE: in the future we'll possibly remove all direct reads of max_length
- Fixing Item_num::safe_charset_converter().
Previously it alligned binary string to
character string (for example by adding leading 0x00
when doing binary->UCS2 conversion). Now it just
converts from my_charset_numbner to "tocs".
- Using val_str_ascii() in Item::get_time() to make UCS2 arguments work.
- Other misc changes
@ sql/item.h
- Changing MY_COLL_CMP_CONV and MY_COLL_ALLOW_CONV to
bit operations instead of hard-coded bit masks.
- Addding new method DTCollation.set_numeric().
- Adding new methods to Item.
- Adding helper functions to make code look nicer:
agg_item_charsets_for_string_result()
agg_item_charsets_for_comparison()
- Changing charset for Item_num-derived items
from my_charset_bin to my_charset_numeric
(which is an alias for latin1).
@ sql/item_cmpfunc.cc
- Using new helper functions
- Other misc changes
@ sql/item_cmpfunc.h
- Fixing strcmp() to return max_length=2.
Previously it returned 1, which was wrong,
because it did not fit '-1'.
@ sql/item_func.cc
- Using new helper functions
- Other minor changes
@ sql/item_func.h
- Removing unused functions
- Adding helper functions
agg_arg_charsets_for_string_result()
agg_arg_charsets_for_comparison()
- Adding set_numeric() into constructors of numeric items.
- Using fix_length_and_charset() and fix_char_length()
instead of direct write to max_length.
@ sql/item_geofunc.cc
- Changing class for Item_func_geometry_type and
Item_func_as_wkt from Item_str_func to
Item_str_ascii_func, to make them return UCS2 result
properly (when character_set_connection=ucs2).
@ sql/item_geofunc.h
- Changing class for Item_func_geometry_type and
Item_func_as_wkt from Item_str_func to
Item_str_ascii_func, to make them return UCS2 result
properly (when @@character_set_connection=ucs2).
@ sql/item_strfunc.cc
- Implementing Item_str_func::val_str().
- Renaming val_str to val_str_ascii for some items,
to make them work with UCS2 properly.
- Using new helper functions
- All single-argument functions that expect string
result now call this method:
agg_arg_charsets_for_string_result(collation, args, 1);
This enables character set conversion to @@character_set_connection
in case of pure numeric input.
@ sql/item_strfunc.h
- Introducing Item_str_ascii_func - for functions
which return pure ASCII data, for performance purposes,
as well as for the cases when the old implementation
of val_str() was heavily 8-bit oriented and implementing
a UCS2-aware version is tricky.
@ sql/item_sum.cc
- Using new helper functions.
@ sql/item_timefunc.cc
- Using my_charset_numeric instead of my_charset_bin.
- Using fix_char_length(), fix_length_and_charset()
and fix_length_and_charset_datetime()
instead of direct write to max_length.
- Using tricky-charset aware function str_to_time_with_warn()
@ sql/item_timefunc.h
- Using new helper functions for charset and length initialization.
- Changing base class for Item_func_get_format() to make
it return UCS2 properly (when character_set_connection=ucs2).
@ sql/item_xmlfunc.cc
- Using new helper function
@ sql/my_decimal.cc
- Adding a new DECIMAL to CHAR converter
with real multibyte support (e.g. UCS2)
@ sql/mysql_priv.h
- Introducing a new derivation level for numeric/datetime data types.
- Adding macros for my_charset_numeric and MY_REPERTOIRE_NUMERIC.
- Adding prototypes for str_set_decimal()
- Adding prototypes for character-set aware str_to_xxx() functions.
@ sql/protocol.cc
- Changing charsetnr to "binary" client-side metadata for
numeric/datetime data types.
@ sql/time.cc
- Adding to_ascii() helper function, to convert a string
in any character set to ascii representation. In the
future can be extended to understand digits written
in various non-Latin word scripts.
- Adding real multy-byte character set aware versions for str_to_XXXX,
to make these these type of queries work correct:
INSERT INTO t1 SET datetime_column=ucs2_expression;
@ strings/ctype-ucs2.c
- endptr was not calculated correctly. INSERTing of UCS2
values into numeric columns returned warnings about
truncated wrong data.
