      Bug#33675: Usage of an uninitialized memory by filesort in a subquery caused · 8845553a
      unknown authored
      server crash.
      
      The filesort implementation has an optimization for subquery execution which
      consists of reusing previously allocated buffers. In particular the call to
      the read_buffpek_from_file function might be skipped when a big enough buffer
      for buffer descriptors (buffpeks) is already allocated. Beside allocating
      memory for buffpeks this function fills allocated buffer with data read from
      disk. Skipping it might led to using an arbitrary memory as fields' data and
      finally to a crash.
      
      Now the read_buffpek_from_file function is always called. It allocates
      new buffer only when necessary, but always fill it with correct data.

      Fix for bug #33305: Test case in 'skip_grants' file need dynamic loading · bdad41ba
      unknown authored
                          to be compiled in
      
      The problem was that on a statically built server an attempt to create
      a UDF resulted in a different, but reasonable error ("Can't open shared
      library" instead of "UDFs are unavailable with the --skip-grant-tables
      option"), which caused a failure for the test case for bug #32020.
      
      Fixed by moving the test case for bug #32020 from skip_grants.test to a
      separate test to ensure that it is only run when the server is built
      with support for dynamically loaded libraries.

      Bug #33256: CREATE ... SELECT creates obsolete table · 2ae4b047
      unknown authored
       w/ Field_date instead of Field_newdate
        
      Field_date was still used in temp table creation.
      Fixed by using Field_newdate consistently throughout the server
      except when reading tables defined with older MySQL version.
      No test suite is possible because both Field_date and Field_newdate
      return the same values in all the metadata calls.

      Fixed bug #27848. · 3f6073ae
      unknown authored
      In a union without braces, the order by at the end is applied to the 
      overall union. It therefore should not interfere with the individual
      select parts of the union.
      
      Fixed by changing our parser rules appropriately.

      Bug#32798: DISTINCT in GROUP_CONCAT clause fails when ordering by a column · 0c4b3f57
      unknown authored
      with null values
      
      For queries containing GROUP_CONCAT(DISTINCT fields ORDER BY fields), there 
      was a limitation that the DISTINCT fields had to be the same as ORDER BY 
      fields, owing to the fact that one single sorted tree was used for keeping 
      track of tuples, ordering and uniqueness. Fixed by introducing a second 
      structure to handle uniqueness so that the original structure has only to 
      order the result.

      Bug #32858: Erro: "Incorrect usage of UNION and INTO" does not take · 93e3057b
      unknown authored
      subselects into account
      
      It is forbidden to use the SELECT INTO construction inside UNION statements
      unless on the last SELECT of the union. The parser records whether it 
      has seen INTO or not when parsing a UNION statement. But if the INTO was
      legally used in an outer query, an error is thrown if UNION is seen in a
      subquery. Fixed in 5.0 by remembering the nesting level of INTO tokens and 
      mitigate the error unless it collides with the UNION.
