when a divisor is less than 1 and its fractional part is very long.
For example:
1 % .123456789123456789123456789123456789123456789123456789123456789123456789123456789;
Stack buffer overflow has been fixed in the do_div_mod function.

and for bug #31070: crash during conversion of charsets
Problem: passing a 0 byte length string to some my_mb_wc_XXX()
functions leads to server crash due to improper argument check.
Fix: properly check arguments passed to my_mb_wc_XXX() functions.

Two character mappings were way off (backtick and tilde were "E"
and "Y"!), and three others were slightly rotated. The first
would cause collisions, and the latter was probably benign.
Now, assign the character mappings exactly to their normal values.

(Regression, caused by a patch for the bug 22646).
Problem: when result type of date_format() was changed from
binary string to character string, mixing date_format()
with a ascii column in CONCAT() stopped to work.
Fix:
- adding "repertoire" flag into DTCollation class,
to mark items which can return only pure ASCII strings.
- allow character set conversion from pure ASCII to other character sets.

with the space character.
When the my_strnncollsp_simple function compares two strings and one is a prefix
of another then this function compares characters in the rest of longer key
with the space character to find whether the longer key is greater or less.
But the sort order of the collation isn't used in this comparison. This may
lead to a wrong comparison result, wrongly created index or wrong order of the
result set of a query with the ORDER BY clause.
Now the my_strnncollsp_simple function uses collation sort order to compare
the characters in the rest of longer key with the space character.

Problem: wrong comparison with trailing space.
This problem was fixed for all other character sets under terms of
bug 7788 ""Table is full" occurs during a multitable update".
ctype-cp932.c was forgotten.
Fix: applying the same fix for ctype-cp932.c.
(see ctype-sjis.c as an example of a previously correctly fixed file)

Problem: like_range() returned wrong ranges for contractions (like 'ch' in Czech').
Fix: adding a special code to handle tricky cases:
- contraction head followed by a wild character
- full contraction
- contraction part followed by another contraction part,
but they are not a contraction together.

- Adding missing initialization for utf8 collations
- Minor code clean-ups: renaming variables,
moving code into a new separate function.
- Adding test, to check that both ucs2 and utf8 user
defined collations work (ucs2_test_ci and utf8_test_ci)
- Adding Vietnamese collation as a complex user defined
collation example.

Problem: "SELECT INTO OUTFILE" created incorrect dumps for BLOBs,
so "LOAD DATA" later incorrectly interpreted 0x5C as the second
byte of a multi-byte sequence, instead of escape character.
Fix: adding escaping of multi-byte heads.

It just sets those digits to 0.

Problem:
HASH indexes on VARCHAR columns with binary collations did not ignore trailing spaces from strings before comparisons. This could result in duplicate records being successfully inserted into a MEMORY table with unique key constraints.
As a direct consequence of the above, internal MEMORY tables used for GROUP BY calculation in testcases for bug #27643 contained duplicate rows which resulted in duplicate key errors when converting those temporary tables to MyISAM. Additionally, that error was incorrectly converted to the 'table is full' error.
Solution:
- ignore trailing spaces in VARCHAR fields with binary collations when calculating hashes.
- return a proper error from create_myisam_from_heap() when conversion fails.

truncated to 31 digits"
When storing a large number to a FLOAT or DOUBLE field with fixed length, it could be incorrectly truncated if the field's length was greater than 31.
This patch also does some code cleanups to be able to reuse code which is common between Field_float::store() and Field_double::store().

- Since isinf() portability across various platforms and
compilers is a complicated question, we should not use
it directly. Instead, the my_isinf() macro should be used,
which is defined as an alias to the system-defined isinf()
if it is safe to use, or a workaround implementation otherwise

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.
