      Fixed bug #33833. · 5e14047e
      igor@olga.mysql.com authored
      Two disjuncts containing equalities of the form key=const1 and key=const2 can
      be merged into one if const1 is equal to const2. To check it the common 
      collation of the constants were used rather than the collation of the field key.
      For example when the default collation of the constants was cases insensitive
      while the collation of the field was case sensitive, then two or-ed equality 
      predicates key='b' and key='B' incorrectly were merged into one f='b'. As a 
      result ref access was used instead of range access and wrong result sets were 
      returned in many cases. 
      Fixed the problem by comparing constant in the or-ed predicate with collation of
      the key field.

      Bug#33143: Incorrect ORDER BY for ROUND()/TRUNCATE() result · effe27e3
      mhansson/martin@linux-st28.site authored
      The ROUND(X, D) function would change the Item::decimals field during
      execution to achieve the effect of a dynamic number of decimal digits.
      This caused a series of bugs:
      Bug #30617:Round() function not working under some circumstances in InnoDB
      Bug #33402:ROUND with decimal and non-constant cannot round to 0 decimal places
      Bug #30889:filesort and order by with float/numeric crashes server
      Fixed by never changing the number of shown digits for DECIMAL when
      used with a nonconstant number of decimal digits.

      Bug#33675: Usage of an uninitialized memory by filesort in a subquery caused · ce111a0d
      evgen@moonbone.local 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 · 578b3632
      kaa@polly.(none) 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.
