      Bug #39002: The server crashes on the query: · 6f94324f
      Gleb Shchepa authored
        INSERT .. SELECT .. ON DUPLICATE KEY UPDATE col=DEFAULT
      
      In order to get correct values from update fields that
      belongs to the SELECT part in the INSERT .. SELECT .. ON
      DUPLICATE KEY UPDATE statement, the server adds referenced
      fields to the select list. Part of the code that does this
      transformation is shared between implementations of
      the DEFAULT(col) function and the DEFAULT keyword (in
      the col=DEFAULT expression), and an implementation of
      the DEFAULT keyword is incomplete.

      BUG#35478: sort_union() returns bad data when sort_buffer_size is hit · 2951f00b
      Sergey Petrunia authored
      - In QUICK_INDEX_MERGE_SELECT::read_keys_and_merge: when we got table->sort from Unique,
        tell init_read_record() not to use rr_from_cache() because a) rowids are already sorted
        and b) it might be that the the data is used by filesort(), which will need record rowids
        (which rr_from_cache() cannot provide).
      - Fully de-initialize the table->sort read in QUICK_INDEX_MERGE_SELECT::get_next(). This fixes BUG#35477.
      (bk trigger: file as fix for BUG#35478).

      Bug#35577 (CREATE PROCEDURE causes either crash or syntax error depending on · 0816ee6d
      Marc Alff authored
      build)
      
      The crash was caused by freeing the internal parser stack during the parser
      execution.
      This occured only for complex stored procedures, after reallocating the parser
      stack using my_yyoverflow(), with the following C call stack:
      - MYSQLparse()
      - any rule calling sp_head::restore_lex()
      - lex_end()
      - x_free(lex->yacc_yyss), xfree(lex->yacc_yyvs)
      
      The root cause is the implementation of stored procedures, which breaks the
      assumption from 4.1 that there is only one LEX structure per parser call.
      
      The solution is to separate the LEX structure into:
      - attributes that represent a statement (the current LEX structure),
      - attributes that relate to the syntax parser itself (Yacc_state),
      so that parsing multiple statements in stored programs can create multiple
      LEX structures while not changing the unique Yacc_state.
      
      Now, Yacc_state and the existing Lex_input_stream are aggregated into
      Parser_state, a structure that represent the complete state of the (Lexical +
      Syntax) parser.

      Bug#26030 (Parsing fails for stored routine w/multi-statement execution · f3ff1aeb
      Marc Alff authored
      enabled)
      
      Before this fix, the lexer and parser would treat the ';' character as a
      different token (either ';' or END_OF_INPUT), based on convoluted logic,
      which failed in simple cases where a stored procedure is implemented as a
      single statement, and used in a multi query.
      
      With this fix:
      - the character ';' is always parsed as a ';' token in the lexer,
      - parsing multi queries is implemented in the parser, in the 'query:' rules,
      - the value of thd->client_capabilities, which is the capabilities
        negotiated between the client and the server during bootstrap,
        is immutable and not arbitrarily modified during parsing (which was the
        root cause of the bug)

      Bug #37150 Risk for crash in User_var_log_event::exec_event() · b9d6d4c0
      Mats Kindahl authored
      On certain kinds of errors (e.g., out of stack), a call to Item_func_
      set_user_var::fix_fields() might fail.  Since the return value of this
      call was not checked inside User_var_log_event::exec_event(), continuing
      execution after this will cause a crash inside Item_func_set_user_var::
      update_hash().
      
      The bug is fixed by aborting execution of the event with an error if
      fix_fields() fails, since it is not possible to continue execution anyway.

      Bug#37380 - Test funcs_1.is_columns_myisam_embedded fails on OS X · 8d5dc3a5
      Patrick Crews authored
      Test was failing due to the addition of a '\x05' character in result sets
      Latest builds of the server have shown this problem to have disappeared.
      Removing code within the test that disables the test on Mac OS X.
      
      Recommit due to tree error on earlier, approved patch.

         Bug#36787 Test funcs_1.charset_collation_1 failing
      Details:
      1. Skip charset_collation_1 if charset "ucs2_bin" is
         missing (property which distincts "vanilla" builds
         from the others)
      2. Let builds with version_comment LIKE "%Advanced%"
         (found them for 5.1) execute charset_collation_3.
      3. Update comments charset_collation.inc so that they
         reflect the current experiences.

      Bug#35658 (An empty binary value leads to mysqld crash)
              
      Before this fix, the following token
        b''
      caused the parser to crash when reading the binary value from the empty string.
      The crash was caused by:
        ptr+= max_length - 1;
      because max_length is unsigned and was 0, causing an overflow.
              
      With this fix, an empty binary literal b'' is parsed as a binary value 0,
      in Item_bin_string.
