Sergei Golubchik	a229091953	potential signedness issue different fix for 07a33cdcef: Bug #23296299 : HANDLE_FATAL_SIGNAL (SIG=11) IN MY_TOSORT_UTF32	9 years ago
Sergei Golubchik	e81455bb16	MDEV-7973 bigint fail with gcc 5.0 -LONGLONG_MIN is the undefined behavior in C. longlong2decimal() used to do this: int longlong2decimal(longlong from, decimal_t to) { if ((to->sign= from < 0)) return ull2dec(-from, to); return ull2dec(from, to); and later in ull2dec() (DIG_BASE is 1000000000): static int ull2dec(ulonglong from, decimal_t to) { for (intg1=1; from >= DIG_BASE; intg1++, from/=DIG_BASE) {} this breaks in gcc-5 at -O3. Here ull2dec is inlined into longlong2decimal. And gcc-5 believes that 'from' in the inlined ull2dec is always a positive integer (indeed, if it was negative, then -from was used instead). So gcc-5 uses signed comparison with DIG_BASE. Fix: make a special case for LONGLONG_MIN, don't negate it	11 years ago
Kailasnath Nagarkar	07a33cdcef	Bug #23296299 : HANDLE_FATAL_SIGNAL (SIG=11) IN MY_TOSORT_UTF32 This patch is specific for mysql-5.5 ISSUE: When a charater that is larger than possible to handle is passed to function my_tosort_utf32(), it results in segmentation fault. In the scenario mentioned in the bug AES_ENCRYPT function is used which returns large value. This value is further passed to my_tosort_utf32 function. This causes to cross array bound for array uni_plane, resulting in segment violation. SOLUTION: This issue has got addressed in 5.6 onward releases through worklog 2673. The fix is similar backport of that. Check for maximum character before accessing the array uni_plane. In addition to function my_tosort_utf32, the same potential problem is also present in functions my_tolower_utf16, my_toupper_utf16, my_tosort_utf16, my_tolower_utf32, my_toupper_utf32, my_tosort_unicode, my_tolower_utf8mb4 and my_toupper_utf8mb4. Fixed these functions as well.	9 years ago
Alexander Barkov	25e68c5e46	MDEV-8686 A user defined collation utf8_confusables doesn't work The collation customization code for the UCA (Unicode Collation Alrorithm) based collations now allows to reset to and shift of characters with implicit weights. Previously reset/shift worked only for the characters with explicit DUCET weights. An attempt to use reset/shift with character with implicit weights made the server crash.	9 years ago
