      Bug #29543 GCov information not written in case of crash. · 1ec3e7f4
      unknown authored
      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.

      Fixed bug #29442. · bed05531
      unknown authored
      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.
      sql/sql_class.cc:
        Fixed bug #29442.
        The select_export::send_data method has been modified to encode text
        representation of fields of all data types like string fields.

      Bug #29166: · 61d616dd
      unknown authored
      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).

      BUG#27564 - Valgrind: UDF does not cleanup correctly · 632ed804
      unknown authored
      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.

      Fixed bug #29392. · b7f5b7b0
      unknown authored
      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.

      Fixed bug #29294. · 36bb14d6
      unknown authored
      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:
        Fixed bug #29294.
        Added commentary for the READ_INFO::unescape method.

      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.

        The function merge_buffers() when called from the Uniques::get method
        must use function buffpek_compare to compare elements in the queue it
        employs. The pointer to buffpek_compare and the info for the function
        that compares sorted records are passed to merge_buffers through certain 
        designated fields of the SORTPARAM structure.
      sql/sql_sort.h:
        Fixed bug #25798.
        Added fields to the SORTPARAM structure to be used in the function 
        merge_buffers when called by the Uniques::get method.
