The problem occurred when one had a subquery that had an equality X=Y where 
Y referred to a named select list expression from the parent select. MySQL 
crashed when trying to use the X=Y equality for ref-based access. 

Fixed by allowing non-Item_field items in the described case.

  get_store_key() assumed that if it got a reference

  then x was an Item_field object, which is not the case when one refers to a
  named select list expression out ot subquery.

The name resolution for correlated subqueries and HAVING clauses
failed to distinguish which of two was being performed when there 
was a reference to an outer aliased field.

is being performed.

value when inserting into a view.

The mysql_prepare_insert function checks all fields of the target table that
directly or indirectly (through a view) are specified in the INSERT
statement to have a default value. This check can be skipped if the INSERT
statement doesn't mention any insert fields. In case of a view this allows
fields that aren't mentioned in the view to bypass the check.

Now fields of the target table are always checked to have a default value
when insert goes into a view.

  Added a test case for the bug#29477: Not all fields of the target table were

When resolving references we need to take into consideration
the view "fields" and allow qualified access to them.
Fixed by extending the reference resolution to process view
fields correctly.

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.

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.

 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.
