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
because the function my_decimal_length_to_precision did not guarantee
returning decimal precision not greater than DECIMAL_MAX_PRECISION.

  The problem appeared the constructors of the class Field_new_decimal
  because the function my_decimal_length_to_precision did not guarantee
  returning decimal precision not greater than DECIMAL_MAX_PRECISION.
  
  Now if the precision returned by calls to my_decimal_length_to_precision
  in the constructors of the class Field_new_decimal is greater than 
  DECIMAL_MAX_PRECISION the precision is set to this value.

The cast operation ignored the cases when the precision and/or the scale exceeded
the limits, 65 and 30 respectively. No errors were reported in these cases.
For some queries this may lead to an assertion abort.

For GCov builds, if the server crashes, the normal exit handler for writing
coverage information is not executed due to the abnormal termination.

Fix this by explicitly calling the __gcov_flush function in our crash handler.

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.

  Updated test case for bug #29442.

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.

  Windows compilation error fix.


sql/sql_class.cc:
  Windows compilation error fix.

The `SELECT 'r' INTO OUTFILE ... FIELDS ENCLOSED BY 'r' ' statement
encoded the 'r' string to a 4 byte string of value x'725c7272'
(sequence of 4 characters: r\rr).
The LOAD DATA statement decoded this string to a 1 byte string of
value x'0d' (ASCII Carriage Return character) instead of the original
'r' character.
The same error also happened with the FIELDS ENCLOSED BY clause
followed by special characters: 'n', 't', 'r', 'b', '0', 'Z' and 'N'.

NOTE 1: This is a result of the undocumented feature: the LOAD DATA INFILE
recognises 2-byte input sequences like \n, \t, \r and \Z in addition
to documented 2-byte sequences: \0 and \N. This feature should be
documented (here backspace character is a default ESCAPED BY character,
in the real-life example it may be any ESCAPED BY character).

NOTE 2, changed behaviour:
Now the `SELECT INTO OUTFILE' statement with the `FIELDS ENCLOSED BY'
clause followed by one of: 'n', 't', 'r', 'b', '0', 'Z' or 'N' characters
encodes this special character itself by doubling it ('r' --> 'rr'),
not by prepending it with an escape character.


sql/sql_class.h:
  Fixed bug #29294.
  The ESCAPE_CHARS macro constant is defined to enumerate
  symbolic names of espace-sequences like  '\n', '\t' etc.
  The select_export::is_ambiguous_field_sep field has been added
  to distinguish special values of the field_sep field from
  another values (see ESCAPE_CHARS).
sql/sql_class.cc:
  Fixed bug #29294.
  The select_export::send_data method has been modified to
  encode special values of the field_sep field by
  doubling of those values instead of prepending them with a
  value of the escape_char field.
  Example: The SELECT 'r' INTO OUTFILE FIELDS ENCLOSED BY 'r'
  now produces the 'rr' output string instead of x'5c72'
  (i.e. instead of sequence of 2 bytes: \ and r).
sql/sql_load.cc:

This bug may manifest itself not only with the queries for which
the index-merge access method is chosen. It also may display
itself for queries with DISTINCT.

The bug was in how the Unique::get method used the merge_buffers
function. To compare elements in the the queue employed by
merge_buffers() it must use the buffpek_compare function rather
than the function for binary comparison.

  designated fields of the SORTPARAM structure.
