      Bug#45010: invalid memory reads during parsing some strange statements · c7163c63
      Davi Arnaut authored
      The problem is that the lexer could inadvertently skip over the
      end of a query being parsed if it encountered a malformed multibyte
      character. A specially crated query string could cause the lexer
      to jump up to six bytes past the end of the query buffer. Another
      problem was that the laxer could use unfiltered user input as
      a signed array index for the parser maps (having upper and lower
      bounds 0 and 256 respectively).
      
      The solution is to ensure that the lexer only skips over well-formed
      multibyte characters and that the index value of the parser maps
      is always a unsigned value.
      
      mysql-test/r/ctype_recoding.result:
        Update test case result: ending backtick is not skipped over anymore.
      sql/sql_lex.cc:
        Characters being analyzed must be unsigned as they can be
        used as indexes for the parser maps. Only skip over if the
        string is a valid multi-byte sequence.

        Add test case for Bug#45010

      Bug#46454: MySQL wrong index optimisation leads to incorrect result & crashes · 4c3917b6
      Martin Hansson authored
      Problem 1:
      When the 'Using index' optimization is used, the optimizer may still - after
      cost-based optimization - decide to use another index in order to avoid using
      a temporary table. But when this happens, the flag to the storage engine to 
      read index only (not table) was still set. Fixed by resetting the flag in the 
      storage engine and TABLE structure in the above scenario, unless the new index
      allows for the same optimization.
      Problem 2:
      When a 'ref' access method was employed by cost-based optimizer, (when the column
      is non-NULLable), it was assumed that it needed no initialization if 'quick' access
      methods (since they are based on range scan). When ORDER BY optimization overrides 
      the decision, however, it expects to have this initialized and hence crashes. 
      Fixed in 5.1 (was fixed in 6.0 already) by initializing 'quick' even when there's 
      'ref' access.

      Fix for BUG#45816 - assertion failure with index containing double · d933cb16
      Satya B authored
                          column on partitioned table
            
            
      An assertion 'ASSERT_COULUMN_MARKED_FOR_READ' is failed if the query 
      is executed with index containing double column on partitioned table.
      The problem is that assertion expects all the fields which are read,
      to be in the read_set.
            
      In this query only the field 'a' is in the readset as the tables in
      the query are joined by the field 'a' and so the assertion fails 
      expecting other field 'b'.
            
      Since the function cmp() is just comparison of two parameters passed, 
      the assertion is not required.
            
      Fixed by removing the assertion in the double fields comparision
      function and also fixed the index initialization to do ordered
      index scan with RW LOCK which ensures all the fields from a key are in
      the read_set.
       
      
      Note: this bug is not reproducible with other datatypes because the
            assertion doesn't exist in comparision function for other 
            datatypes.

        Fixed index_int() method to make it initialize the read_set properly if
        ordered index scan with RW lock is requested.

      BUG#43264 Test rpl_trigger is failing randomly w/ use of copy_file in 5.0 · 968ec5ea
      Alfranio Correia authored
      The test case fails sporadically on Windows while trying to overwrite an unused
      binary log. The problem stems from the fact that MySQL on Windows does not
      immediately unlock/release a file while the process that opened and closed it is
      still running. In BUG 38603, this issue was circumvented by stopping the MySQL
      process, copying the file and then restarting the MySQL process. 
      
      Unfortunately, such facilities are not available in the 5.0.  Other approaches
      such as stopping the slave and issuing change master do not work because the relay
      log file and index are not closed when a slave is stopped. So to fix the problem,
      we simply don't run on windows the part of the test that was failing.

      Bug# 30946: mysqldump silently ignores --default-character-set · 4e95179a
      Gleb Shchepa authored
                  when used with --tab
      
      1) New syntax: added CHARACTER SET clause to the
        SELECT ... INTO OUTFILE (to complement the same clause in
        LOAD DATA INFILE).
        mysqldump is updated to use this in --tab mode.
      
      2) ESCAPED BY/ENCLOSED BY field parameters are documented as
         accepting CHAR argument, however SELECT .. INTO OUTFILE
         silently ignored rests of multisymbol arguments.
         For the symmetrical behavior with LOAD DATA INFILE the
         server has been modified to fail with the same error:
      
           ERROR 42000: Field separator argument is not what is
                        expected; check the manual
      
      3) Current LOAD DATA INFILE recognizes field/line separators
         "as is" without converting from client charset to data
         file charset. So, it is supposed, that input file of
         LOAD DATA INFILE consists of data in one charset and
         separators in other charset. For the compatibility with
         that [buggy] behaviour SELECT INTO OUTFILE implementation
         has been saved "as is" too, but the new warning message
         has been added:
      
           Non-ASCII separator arguments are not fully supported
      
         This message warns on field/line separators that contain
         non-ASCII symbols.
      
      
      client/mysqldump.c:
        mysqldump has been updated to call SELECT ... INTO OUTFILE
        statement with a charset from the --default-charset command
        line parameter.
      mysql-test/r/mysqldump.result:

        to convert_to_printable() for reuse.
      sql/share/errmsg.txt:
        New WARN_NON_ASCII_SEPARATOR_NOT_IMPLEMENTED message has been added.
      sql/sql_class.cc:
        The select_export::prepare() method has been modified to:
        
          1) raise the ER_WRONG_FIELD_TERMINATORS error on multisymbol
             ENCLOSED BY/ESCAPED BY field arguments like LOAD DATA INFILE;
        
          2) warn with a new WARN_NON_ASCII_SEPARATOR_NOT_IMPLEMENTED
             message on non-ASCII field or line separators.
        
        The select_export::send_data() merhod has been modified to
        convert item data to output charset (see new SELECT INTO OUTFILE
        syntax). By default the BINARY charset is used for backward
        compatibility.
      sql/sql_class.h:
        The select_export::write_cs field added to keep output
        charset.
      sql/sql_load.cc:
        mysql_load has been modified to warn on non-ASCII field or
        line separators with a new WARN_NON_ASCII_SEPARATOR_NOT_IMPLEMENTED

        New String::is_ascii() method and new global convert_to_printable()
        function have been added.

        New syntax: added CHARACTER SET clause to the

      Bug#46265: Can not disable warning about unsafe statements for binary logging · 7d8b967a
      Davi Arnaut authored
      If using statement based replication (SBR), repeatedly calling
      statements which are unsafe for SBR will cause a warning message
      to be written to the error for each statement. This might lead
      to filling up the error log and there is no way to disable this
      behavior.
      
      The solution is to only log these message (about statements unsafe
      for statement based replication) if the log_warnings option is set.
      
      For example:
      
      SET GLOBAL LOG_WARNINGS = 0;
      INSERT INTO t1 VALUES(UUID());
      SET GLOBAL LOG_WARNINGS = 1;
      INSERT INTO t1 VALUES(UUID());
      
      In this case the message will be printed only once:
      
      [Warning] Statement may not be safe to log in statement format.
                Statement: INSERT INTO t1 VALUES(UUID())
      
      mysql-test/suite/binlog/r/binlog_stm_unsafe_warning.result:
        Add test case result for Bug#46265
      mysql-test/suite/binlog/t/binlog_stm_unsafe_warning-master.opt:
        Make log_error value available.
      mysql-test/suite/binlog/t/binlog_stm_unsafe_warning.test:
        Add test case for Bug#46265
      sql/sql_class.cc:
        Print warning only if the log_warnings is enabled.

      Bug#40281, partitioning the general log table crashes the server · 717d6054

      We disallow the partitioning of a log table. You could however
      partition a table first, and then point logging to it. This is

      We catch this case now.

        to crash the server
      sql/ha_partition.cc:
        Signal that we no longer support logging to partitioned tables,
        as per the docs.
      sql/sql_partition.cc:
        Some commands like "USE ..." have no select, yet we may try
        to parse partition info after their execution if user set a
        partitioned table as log target. This shouldn't lead to a
        NULL-deref/crash.

      Bug#45017: Failure to connect if hostname maps to multiple addresses · 543e8672
      Davi Arnaut authored
      The problem is that the C API function mysql_real_connect
      only attempts to connect to the first IP address returned
      for a hostname. This can be a problem if a hostname maps
      to multiple IP address and the server is not bound to the
      first one that is returned.
      
      The solution is to augment mysql_real_connect so that it
      attempts to connect to all IPv4 addresses that a domain
      name maps to. The function goes over the list of address
      until a successful connection is established.
      
      No test case is provided as its not possible to test this
      automatically with the current testing infrastructure.
      
      sql-common/client.c:
        The client will try to connect to each IPv4 address from
        the list of addresses that hostname maps to until a successful
        connection is established or there are no more address.
