      BUG#49124 Security issue with /*!-versioned */ SQL statements on Slave · ade1c74b
      authored
      Backport to 5.0.
      
      /*![:version:] Query Code */, where [:version:] is a sequence of 5 
      digits representing the mysql server version(e.g /*!50200 ... */),
      is a special comment that the query in it can be executed on those 
      servers whose versions are larger than the version appearing in the 
      comment. It leads to a security issue when slave's version is larger 
      than master's. A malicious user can improve his privileges on slaves. 
      Because slave SQL thread is running with SUPER privileges, so it can
      execute queries that he/she does not have privileges on master.
            
      This bug is fixed with the logic below: 
      - To replace '!' with ' ' in the magic comments which are not applied on
        master. So they become common comments and will not be applied on slave.
            
      - Example:
        'INSERT INTO t1 VALUES (1) /*!10000, (2)*/ /*!99999 ,(3)*/
         will be binlogged as
        'INSERT INTO t1 VALUES (1) /*!10000, (2)*/ /* 99999 ,(3)*/

      Backport of the fix for bug#25421 to 5.0. · a42108c2
      Alexey Kopytov authored
      Calculating the estimated number of records for a range scan
      may take a significant time, and it was impossible for a user
      to interrupt that process by killing the connection or the
      query.
      
      Fixed by checking the thread's 'killed' status in
      check_quick_keys() and interrupting the calculation process if
      it is set to a non-zero value.

      Bug#54041: MySQL 5.0.92 fails when tests from Connector/C suite run · 07767edc
      Davi Arnaut authored
      The problem was that a user could supply supply data in chunks
      via the COM_STMT_SEND_LONG_DATA command to prepared statement
      parameter other than of type TEXT or BLOB. This posed a problem
      since other parameter types aren't setup to handle long data,
      which would lead to a crash when attempting to use the supplied
      data.
      
      Given that long data can be supplied at any stage of a prepared
      statement, coupled with the fact that the type of a parameter
      marker might change between consecutive executions, the solution
      is to validate at execution time each parameter marker for which
      a data stream was provided. If the parameter type is not TEXT or
      BLOB (that is, if the type is not able to handle a data stream),
      a error is returned.

      Bug#54590 "make_binary_distribution" fails because a command · d4c4bd6e
      Joerg Bruehe authored
                 line exceeds the limit
      
      The number and/or names of our files for the main test suite
      (contents of "mysql-test/t/") now exceeds the command line
      length limit on AIX.
      Solve the problem by using separate "cp" commands for the
      various file name extensions.
