An assertion abort could occur for some grouping queries that employed 
decimal user variables with assignments to them.

The problem appeared the constructors of the class Field_new_decimal

The SELECT INTO OUTFILE FIELDS ENCLOSED BY digit or minus sign,
followed by the same LOAD DATA INFILE statement, used wrond encoding
of non-string fields contained the enclosed character in their text
representation.

Example:
  SELECT 15, 9 INTO OUTFILE 'text' FIELDS ENCLOSED BY '5';

Old encoded result in the text file:
  5155 595
         ^ was decoded as the 1st enclosing character of the 2nd field;
        ^ was skipped as garbage;
  ^    ^ was decoded as a pair of englosing characters of the 1st field;
      ^   was decoded as traling space of the first field;
    ^^ was decoded as a doubled enclosed character.

New encoded result in the text file:
  51\55 595
  ^   ^ pair of enclosing characters of the 1st field;
    ^^ escaped enclosed character.



sql/sql_class.h:
  Fixed bug #29442.
  The NUMERIC_CHARS macro constant has been defined to enumerate
  all possible characters of a numeric value text representation.
  The select_export::is_unsafe_field_sep boolean flag has been added
  to apply the encoding algorithm to non-string values when it is
  necessary.

AsText() needs to know the maximum number of
characters a IEEE double precision value can
occupy to make sure there's enough buffer space.
The number was too small to hold all possible
values and this caused buffer overruns.
Fixed by correcting the calculation of the 
maximum digits in a string representation of an
IEEE double precision value as printed by 
String::qs_append(double).

Dropping an user defined function may cause server crash in
case this function is still in use by another thread.

The problem was that our hash implementation didn't update
hash link list properly when hash_update() was called.


mysys/hash.c:
  The following requirement wasn't met by hash_update() function
  causing corruption of hash links list:
  
  After a record was unlinked from the old chain during update, it
  holds random position. By the chance this position is equal to
  position for the first element in the new chain. That means
  updated record is the only record in the new chain.

This bug may manifest itself for select queries over a multi-table view
that includes an ORDER BY clause in its definition. If the select list of 
the query contains references to the same view column with different
aliases the names of the columns in the result output will be nevertheless
the same, coinciding with one of the alias.

The bug happened because the method Item_ref::get_tmp_table_item that
was inherited by the class Item_direct_view_ref ignored the fact that
the name of the view column reference must be inherited by the fields
of the temporary table that was created in order to get the result rows
sorted.
