memory corruptions.

The right pointer field of the SEL_ARG structure was not
initialized in the constructor and sometimes that led to
server crashes.

There is no testcase because the bug occurs only when
uninitialized memory has particular values, which can't be
re-created in the test suite.


sql/opt_range.cc:
  Fixed bug #32403.
  
  The eq_tree function requires that SEL_ARG::left and
  SEL_ARG::right are equal to null pointer if SEL_ARG
  type is MAYBE_KEY, but SEL_ARG::right was not initialized
  and contained garbage.

bytes length.

The server has been modified to report warnings on truncation to
65536 bytes as usual.



sql/sql_string.cc:
  Fixed bug #32282.
  The well_formed_copy_nchars function returned an incorrect value
  of copied bytes of the truncated input string: extra length of
  the first truncated character added to the *from_end_pos pointer.
  That has been fixed.

Comparison of a BIGINT NOT NULL column with a constant arithmetic
expression that evaluates to NULL caused error 1048: "Column '...'
cannot be null".

Made convert_constant_item() check if the constant expression is NULL
before attempting to store it in a field. Attempts to store NULL in a
NOT NULL field caused query errors.

The columns in HAVING can reference the GROUP BY and 
SELECT columns. There can be "table" prefixes when
referencing these columns. And these "table" prefixes
in HAVING use the table alias if available.
This means that table aliases are subject to the same
storage rules as table names and are dependent on 
lower_case_table_names in the same way as the table 
names are.
Fixed by :
1. Treating table aliases as table names
and make them lowercase when printing out the SQL
statement for view persistence.
2. Using case insensitive comparison for table 
aliases when requested by lower_case_table_names

When we insert a record into MYISAM table which is almost 'full',
we first write record data in the free space inside a file, and then
check if we have enough space after the end of the file.
So if we don't have the space, table will left corrupted.
Similar error also happens when we updata MYISAM tables.

Fixed by modifying write_dynamic_record and update_dynamic_record functions
to check for free space before writing parts of a record
