Item_in_subselect's only externally callable method is val_bool().
However the nullability in the wrapper class (Item_in_optimizer) is 
established by calling the "forbidden" method val_int().

Fixed to use the correct method (val_bool() ) to establish nullability 
of Item_in_subselect in Item_in_optimizer.

There are two problems with ROUND(X, D) on an exact numeric 
(DECIMAL, NUMERIC type) field of a table:
1) The implementation of the ROUND function would change the number of decimal
places regardless of the value decided upon in fix_length_and_dec. When the
number of decimal places is not constant, this would cause an inconsistent
state where the number of digits was less than the number of decimal places,
which crashes filesort.

Fixed by not allowing the ROUND operation to add any more decimal places than
was decided in fix_length_and_dec.

2) fix_length_and_dec would allow the number of decimals to be greater than
the maximium configured value for constant values of D. This led to the same 
crash as in (1).

Fixed by not allowing the above in fix_length_and_dec.

storage/archive/ha_archive.cc:
  Fixed bug #31036.
  1. Memory overrun has been fixed: maximal sizes of azio_stream::inbuf
     and azio_stream::outbuf was mixed.
  2. Zero value of the output parameter of the azread function was
     incorrectly interpreted by the azseek function: after the first
     successful read attempt the execution of the azseek loop was
     interrupted and negative value was returned.
     (See ha_archive::rnd_pos: that negative value was silently ignored,
     and an incomplete data was used, for example, as a size of a packed
     record, and server failed with the assertion:
     "row_len <= record_buffer->length".)

SHOW FIELDS FROM a view with no valid definer was possible (since fix
for Bug#26817), but gave NULL as a field-type. This led to mysqldump-ing
of such views being successful, but loading such a dump with the client
failing. Patch allows SHOW FIELDS to give data-type of field in underlying
table.

  Fix test results: SHOW FIELDS FROM a view with no valid DEFINER

  DEFINER for determining underlying data-type like we usually do.

BitKeeper/deleted/.del-changelog-bleh:
  Rename: BitKeeper/deleted/.del-changelog -> BitKeeper/deleted/.del-changelog-bleh

This is a 5.1 version of the patch.
  
Problem:
  
'log' and 'log_slow_queries' were "fixed" variables, i.e. they showed up
in SHOW VARIABLES, but could not be used in expressions like 
"select @@log". Also, using them in the SET statement produced an 
incorrect "unknown system variable" error.
  
Solution:

Since as of MySQL 5.1.12 one can enable or disable the general query log
or the slow query log at runtime by changing values of
general_log/slow_query_log, make 'log' and 'log_slow_queries" to be 
synonyms for 'general_log' and 'slow_query_log' respectively.  This 
makes expressions using the '@@var' syntax backward compatible with 
5.0 and SHOW VARIABLES output to be consistent with the SET statement.

This is a 5.0 version of the patch, it will be null-merged to 5.1

in SHOW VARIABLES, but could not be used in expressions like 
"select @@log". Also, using them in the SET statement produced an 
incorrect "unknown system variable" error.

Solution:

Make 'log' and 'log_slow_queries' read-only dynamic variables to make 
them available for use in expressions, and produce a correct error 
about the variable being read-only when used in the SET statement.

The optimizer pre-calculates the MIN/MAX values for queries like
 SELECT MIN(kp_k) WHERE kp_1 = const AND ... AND kp_k-1 = const
when there is a key over kp_1...kp_k
In doing so it was not checking correctly nullability and 
there was a superfluous assert(). 
Fixed by making sure that the field can be null before checking and
taking out the wrong assert().
