Bugs fixed:
- Added automatic detection of unsigned arguments to COLUMN_CREATE()
- If string length is not know for COLUMN_GET() use MAX_DYNAMIC_COLUMN_LENGTH instead of MAX_FIELD_BLOBLENGTH
- null_value flag was not propery reset for COLUMN_LIST() and COLUMN_CREATE() which could lead to crashes later:
- lp:778905 Assertion `value->year <= 9999' failed in dynamic_column_date_store
- lp:778912 Assertion `field_pos < field_count' failed in Protocol_text::store in maria-5.3-mwl34

Background:
- THD classes derives from Query_arena, thus inherits the 'state'
attribute and related operations (is_stmt_prepare() & co).
- Although these operations are available in THD, they must not
be used. THD has its own attribute to point to the active
Query_arena -- stmt_arena.
- So, instead of using thd->is_stmt_prepare(),
thd->stmt_arena->is_stmt_prepare() must be used. This was the root
cause of Bug 60025.
This patch enforces the proper way of calling those operations.
is_stmt_prepare() & co are declared as private operations
in THD (thus, they are hidden from being called on THD instance).
The patch tries to minimize changes in 5.5.
Problem: comparison of a DATETIME sp variable and NOW()
led to Illegal mix of collations error when
character_set_connection=utf8.
Introduced by "WL#2649 Number-to-string conversions".
Error happened in Arg_comparator::set_compare_func(),
because the first argument was errouneously converted to utf8,
while the second argument was not.
Fix: separate agg_arg_charsets_for_comparison() into two functions:
- agg_arg_charsets_for_comparison() - for pure comparison,
when we don't need to return any string result and therefore
don't need to convert arguments to @@character_set_connection:
SELECT a = b;
- agg_arg_charsets_for_string_results_with_comparison() - when
we need to return a string result, but we also need to do
comparison internally: SELECT REPLACE(a,b,c)
If all arguments are numbers:
SELECT REPLACE(123,2,3) -> 133
we convert arguments to @@character_set_connection.

Analysis:
A query with implicit grouping is one with aggregate functions and
no GROUP BY clause. MariaDB inherits from MySQL an SQL extenstion
that allows mixing aggregate functions with non-aggregate fields.
If a query with such mixed select clause produces an empty result
set, the meaning of aggregate functions is well defined - either
NULL (MIN, MAX, etc.), or 0 (count(*)). However the non-aggregated
fields must also have some value, and the only reasonable value in
the case of empty result is NULL.
The cause of the many wrong results was that if a field is declared
as non-nullable (e.g. because it is a PK or NOT NULL), the semantic
analysis and the optimization phases treat this field as non-nullable,
and generate all related query plan elements based on this assumption.
Later during execution, these incorrectly configured/generated query
plan elements result in a wrong result because the selected fields
are not null due to the not-null assumption during optimization.
Solution:
Detect before the context analysys phase that a query uses implicit
grouping with mixed aggregates/non-aggregates, and set all fields
as nullable. The parser already walks the SELECT clause, and
already sets Item::with_sum_func for Items that reference aggreagate
functions. The patch adds a symmetric Item::with_field so that all
Items that reference an Item_field are marked during their
construction at parse time in the same way as with aggregate function
use.

Item_func_dec_encrypt::val_str() and Item_func_des_descrypt::val_str()
did not set character set for tmp_value (the returned value),
so the old value, which was previously copied from args[1]->val_str(),
was incorrectly returned with tmp_value.
- Fixed some issues with partitions and connection_string, which also fixed lp:716890 "Pre- and post-recovery crash in Aria"

Introduced by the fix for bug#44766.

Some string manipulating SQL functions use a shared string object intended to
contain an immutable empty string. This object was used by the SQL function
SUBSTRING_INDEX() to return an empty string when one argument was of the wrong
datatype. If the string object was then modified by the sql function INSERT(),
undefined behavior ensued.
Fixed by instead modifying the string object representing the function's
result value whenever string manipulating SQL functions return an empty
string.
Relevant code has also been documented.
Problem: DATE_ADD() is a hybrid function and can return
DATE, DATETIME or VARCHAR data type depending on arguments.
In case of VARCHAR data type, DATE_ADD() reported "binary" character set,
which was wrong.
Fix: make DATE_ADD() return @character_set_connection in VARCHAR context.

Problem: LIKE over an indexed column optimized away good results,
because my_like_range_utf32/utf16 returned wrong ranges for contractions.
Contraction related code was missing in my_like_range_utf32/utf16,
but did exist in my_like_range_ucs2/utf8.
It was forgotten in utf32/utf16 versions (during mysql-6.0 push/revert mess).
Fix:
The patch removes individual functions my_like_range_ucs2,
my_like_range_utf16, my_like_range_utf32 and introduces a single function
my_like_range_generic() instead. The new function handles contractions
correctly. It can handle any character set with cs->min_sort_char and
cs->max_sort_char represented in Unicode code points.

@ strings/ctype-ucs2.c
- my_fill_mb2 did not put the high byte, as previously
it was used to put only characters in ASCII range.

(needed to pupulate cs->max_sort_char correctly).
- Adding DBUG_ASSERT()
- Removing character set specific functions:
my_like_range_ucs2(), my_like_range_utf16() and my_like_range_utf32().

Problems:
- dot character was always printed as decimal point

- Item_func_format::val_str always returned values in ASCII
format,
regargless of @@character_set_connection, which in case of utf32
led to crash in debug build, or to incorrect values in release build.
Fix:
- Adding a piece of code to replace dot character to
localized decimal point in short numbers.
- Changing parent class for Item_func_format to
Item_str_ascii_func, because its val_str() implementation is heavily ASCII oriented.

Iterative patch improvement. Previously committed patch
caused wrong result on Windows. The previous patch also
broke secure_file_priv for symlinks since not all file
paths which must be compared against this variable are
normalized using the same norm.
The server variable opt_secure_file_priv wasn't
normalized properly and caused the operations
LOAD DATA INFILE .. INTO TABLE ..
and
SELECT load_file(..)
to do different interpretations of the
--secure-file-priv option.
The patch moves code to the server initialization
routines so that the path always is normalized
once and only once.
It was also intended that setting the option
to an empty string should be equal to
lifting all previously set restrictions. This
is also fixed by this patch.
mysql-test/r/loaddata.result:
* Removed test code which will currently break the much used --mem feature of mtr.
mysql-test/t/loaddata.test:
* Removed test code which will currently break the much used --mem feature of mtr.
sql/item_strfunc.cc:
* Replaced string comparing code on opt_secure_file_priv with an interface which guarantees that both file paths are normalized using the same norm on all platforms.
sql/mysql_priv.h:
* Added signature for is_secure_file_path()
sql/mysqld.cc:
* New function for checking if a path compatible with the secure path restriction.
* Added initialization of the opt_secure_file_priv variable.
sql/sql_class.cc:
* Replaced string comparing code on opt_secure_file_priv with an interface which guarantees that both file paths are normalized using the same norm on all platforms.
sql/sql_load.cc:
* Replaced string comparing code on opt_secure_file_priv with an interface which guarantees that both file paths are normalized using the same norm on all platforms.
The bug was a side effect of WL#5030 (fix header files) and
WL#5161 (CMake).
The problem was that CMake-generated config.h (and my_config.h
as a copy of it) had a header guard. GNU autotools-generated
[my_]config.h did not. During WL#5030 the order of header files
was changed, so the following started to happen (using GNU autotools,
in embedded server):
- my_config.h included, defining HAVE_OPENSSL
- my_global.h included, un-defining HAVE_OPENSSL
- zlib.h included, including config.h,
defining HAVE_OPENSSL again.
The fix is to check HAVE_OPENSSL in conjuction with EMBEDDED_LIBRARY.
More common fix would be to define a macros as HAVE_OPENSSL && !EMBEDDED_LIBRARY
and use it instead of HAVE_OPENSSL.

The fix is to change the order of header file, moving zlib.h
to the top of the header list. More proper fix would be to wrap
unguarded auto-generated [my_]config.h by guarded non-generated
header file.
