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
t.key=Item_outer_ref(Item_direct_ref(x))
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 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.

The name resolution for correlated subqueries and HAVING clauses

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.
mysql-test/t/view.test:
Added a test case for the bug#29477: Not all fields of the target table were

Now fields of the target table are always checked to have a default value

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.

read_buffer_size set on master
BUG#33413 show binlog events fails if binlog has event size of close
to max_allowed_packet
The size of Append_block replication event was determined solely by
read_buffer_size whereas the rest of replication code deals with
max_allowed_packet.
When the former parameter was set to larger than the latter there were
two artifacts: the master could not read events from binlog;
show master events did not show.
Fixed with
- fragmenting the used io-cached buffer into pieces each size of less
than max_allowed_packet (bug#30435)
- incrementing show-binlog-events handling thread's max_allowed_packet
with the max estimated for the replication header size

accessor-macros added in order not to mess with the io cache's implementation
details in code that merely exploits the io-cache.

Complementary patch since LOAD DATA INFILE was not covered in
the previous patch.
This patch adds a check so that the slave skip counter is not
decreased to zero if seeing a BEGIN_LOAD_QUERY_EVENT,
APPEND_BLOCK_EVENT, or CREATE_FILE_EVENT since these cannot
end a group. The group is terminated by an EXECUTE_LOAD_QUERY_
EVENT or DELETE_FILE_EVENT.
mysql-test/r/rpl_slave_skip.result:
Result change.
mysql-test/t/rpl_slave_skip.test:
Adding tests to test that the first event of a LOAD DATA INFILE
can be skipped safely for both transactional and non-transactional
tables. Also include a case that will generate a DELETE_FILE event
last in the group, and this should be properly skipped as well.
sql/slave.cc:
Not decrementing slave skip counter to zero when seeing a
BEGIN_LOAD_QUERY_EVENT, APPEND_BLOCK_EVENT, or CREATE_FILE_EVENT
since these cannot end a group.

The reason of this bug is that when mysqlbinlog dumps a query, the query is written to
output with a delimeter appended right after it, if the query string ends with a '--'
comment, then the delimeter would be considered as part of the comment, if there are any
statements after this query, then it will cause a syntax error.
