      Bug#43183 ExctractValue() brings result list in missorder · b46dc9ca
      Sergey Glukhov authored
      The problem is that XML functions(items) do not reset null_value
      before their execution and further item excution may use
      null_value value of the previous result.
      The fix is to reset null_value.

      Bug#40127 Multiple table DELETE IGNORE hangs on foreign key constraint violation · a20bc967
      Kristofer Pettersson authored
                on 5.0            
      The server crashes on an assert in net_end_statement indicating that the
      Diagnostics area wasn't set properly during execution.
      This happened on a multi table DELETE operation using the IGNORE keyword.
      The keyword is suppose to allow for execution to continue on a best effort
      despite some non-fatal errors. Instead execution stopped and no client
      response was sent which would have led to a protocol error if it hadn't been
      for the assert.
      This patch corrects this issue by checking for the existence of an IGNORE
      option before setting an error state during row-by-row delete iteration.

      Bug#39953 Triggers are not working properly with multi table · 50ed1ef7
      Staale Smedseng authored
      updates
      
      Attempt to execute trigger or stored function with multi-UPDATE
      which used - but didn't update - a table that was also used by
      the calling statement led to an error. Read-only reference to
      tables used in the calling statement should be allowed.
       
      This problem was caused by the fact that check for conflicting
      use of tables in SP/triggers was performed in open_tables(),
      and in case of multi-UPDATE we didn't know exact lock type at
      this stage.
      
      We solve the problem by moving this check to lock_tables(), so
      it can be performed after exact lock types for tables used by
      multi-UPDATE are determined.
      
      
      mysql-test/r/trigger.result:
        Results for the added test case is added.
      mysql-test/t/trigger.test:
        A new test case is added, verifying correct table multi-update
        conflict resolution, both read-only and write.
      sql/sql_base.cc:
        The check for conflicting use of tables in SP/triggers is moved
        to lock_tables(), to be performed after the exact lock types
        have been determined. Also, an assert is added to open_ltable()
        to ensure this func is not used in a prelocked context.

      Fix for bug #43432: Union on floats does unnecessary rounding · 0b60184b
      Alexey Kopytov authored
        
      UNION could convert fixed-point FLOAT(M,D)/DOUBLE(M,D) columns  
      to FLOAT/DOUBLE when aggregating data types from the SELECT  
      substatements. While there is nothing particularly wrong with  
      this behavior, especially when M is greater than the hardware  
      precision limits, it could be confusing in cases when all  
      SELECT statements in a union have the same  
      FLOAT(M,D)/DOUBLE(M,D) columns with equal precision  
      specifications listed in the same position.  
        
      Since the manual is quite vague on what data type should be  
      returned in such cases, the bug was fixed by implementing the  
      most 'expected' behavior: do not convert FLOAT(M,D)/DOUBLE(M,D)  
      to anything else if all SELECT statements in a UNION have the  
      same precision for that column.  
      
      mysql-test/r/union.result:
        Added a test case for bug #43432.
      mysql-test/t/union.test:

        Do not convert FLOAT(M,D)/DOUBLE(M,D) 
        to anything else if all SELECT statements in a UNION have the 
        same precision for that column.
      sql/mysql_priv.h:
        Added a symbolic constant for FLT_DIG+6 and DBL_DIG+7.

      Bug#33899: Deadlock in mysql_real_query with shared memory connections · 7c261213
      Davi Arnaut authored
      The problem is that the read and write methods of the shared
      memory transport (protocol) didn't react to asynchornous close
      events, which could lead to a lock up as the client would wait
      (until time out) for a server response that will never come.
      
      The solution is to also wait for close events while waiting
      for I/O from or to the server.

      BUG#35515 Aliases of variables in binary log are ignored with NAME_CONST. · 944915ca

      When add an aliase name after NAME_CONST, the aliase name will be overwrite.
            
      NAME_CONST will re-set the field's name only if there isn't an aliase in the
      function fix-fields().
      If there is an aliase, NAME_CONST doesn't re-set the field's name and keeps the old
      name.
