      Bug#45010: invalid memory reads during parsing some strange statements · 69fbbdc1
      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.

      Bug#46454: MySQL wrong index optimisation leads to incorrect result & crashes · 5421a8e8
      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 · ad951044
      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.

      Bug #45630 rpl_trigger.test causes valgrind failures within nptl_pthread_exit_hack_handler · 440ddc54
      authored
      The server shutdown and start code triggered the valgrind failures 
      within nptl_pthread_exit_hack_handler on Ubuntu 9.04, x86 (but not amd64) 
      in rpl_trigger.test file.
      
      For fixing the bug, suppress valgrind failures within nptl_pthread_exit_hack_handler 
      on Ubuntu 9.04, x86 (but not amd64). Because the server shutdown and start
      code has been heavily used in mysql test set.

      BUG#43264 Test rpl_trigger is failing randomly w/ use of copy_file in 5.0 · 407520b6
      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#17270 - mysql client tool could not find ../share/charsets folder and fails. · 6df2af22
      Ignacio Galarza authored
      - Define and pass compile time path variables as pre-processor definitions to 
        mimic the makefile build.
      - Set new CMake version and policy requirements explicitly.
      - Changed DATADIR to MYSQL_DATADIR to avoid conflicting definition in 
        Platform SDK header ObjIdl.h which also defines DATADIR.

      Bug# 30946: mysqldump silently ignores --default-character-set · e642140b
      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.

      Bug#46265: Can not disable warning about unsafe statements for binary logging · e1c43705
      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())

      Bug#40281, partitioning the general log table crashes the server · f6b8b9d2
      Tatiana A. Nurnberg authored
      We disallow the partitioning of a log table. You could however
      partition a table first, and then point logging to it. This is
      not only against the docs, it also crashes the server.
      
      We catch this case now.
