- Fixing utf8_general_cs according to recent changes.
- Compiling utf8_general_cs in pentium-debug-max configuration
to avoid these problems in the future.
Problem: GROUP BY on empty ucs2 strings crashed server.
Reason: sometimes mi_unique_hash() is executed with
ptr=null and length=0, which means "empty string".
The branch of code handling UCS2 character set
was not safe against ptr=null and fell into and
endless loop even if length=0 because of poiter
arithmetic overflow.
Fix: adding special check for length=0 to avoid pointer arithmetic
overflow.

more similar to my_strtod() (and maybe even a bit faster due
to less floating point divisions).
This should at least partially fix Bug #23260 for DECIMALs
with a moderate number of total digits.
- Removed not used variables and functions
- Added #ifdef around code that is not used
- Renamed variables and functions to avoid conflicts
- Removed some not used arguments
Fixed some class/struct warnings in ndb
Added define IS_LONGDATA() to simplify code in libmysql.c
I did run gcov on the changes and added 'purecov' comments on almost all lines that was not just variable name changes
Fixed compiler warnings (detected by VC++):
- Removed not used variables
- Added casts
- Fixed wrong assignments to bool
- Fixed wrong calls with bool arguments
- Added missing argument to store(longlong), which caused wrong store method to be called.
(Mostly in DBUG_PRINT() and unused arguments)
Fixed bug in query cache when used with traceing (--with-debug)
Fixed memory leak in mysqldump
Removed warnings from mysqltest scripts (replaced -- with #)
Problem: SHOW CREATE TABLE printed garbage in table
name for tables having TURKISH I
(i.e. LATIN CAPITABLE LETTER I WITH DOT ABOVE)
when lower-case-table-name=1.
Reason: In some cases during lower/upper conversion in utf8,
the result string can be shorter the original string
(including the above letter). Old implementation of caseup_str()
and casedn_str() didn't handle the result length properly,
assuming that length cannot change.
This fix changes the result type of cs->cset->casedn_str()
and cs->cset->caseup_str() from VOID to UINT, to return
the result length, as well as put '\0' terminator on a
proper place.
Also, my_caseup_str_utf8() and my_casedn_str_utf8() were
rewritten not to use strlen() for performance purposes.
It was done with help of adding of new functions - my_utf8_uni_no_range()
and my_uni_utf8_no_range() - for null terminated strings.
decimal->ulong conversion fixed to assign max possible ULONG if decimal
is bigger
Item_func_unsigned now handles DECIMAL parameter separately as we can't
rely on decimal::val_int result here.
LIKE craashed with a pattern having letters in the range 128..255
(e.g. A WITH ACUTE or C WITH CARON) because of wrong cast from
signed char to unsigned int.
The problem was that when converting a string to an exact number,
rounding didn't work, because conversion didn't understand
approximate numbers notation.
Fix: a new function for string-to-number conversion was implemented,
which is aware of approxinate number notation (with decimal point
and exponent, e.g. -19.55e-1)
