doesn't find the column"
When a user was using 4.1 tables with VARCHAR column and 5.0 server
and a query that used a temporary table to resolve itself, the
table metadata for the varchar column sent to client was incorrect:
MYSQL_FIELD::table member was empty.
The bug was caused by implicit "upgrade" from old VARCHAR to new
VARCHAR hard-coded in Field::new_field, which did not preserve
the information about the original table. Thus, the field metadata
of the "upgraded" field pointed to an auxiliary temporary table
created for query execution.
The fix is to copy the pointer to the original table to the new field.

The Item::tmp_table_field_from_field_type() function creates Field_datetime
object instead of Field_timestamp object for timestamp field thus always
changing data type is a tmp table is used.
The Field_blob object constructor which is used in the
Item::tmp_table_field_from_field_type() is always setting packlength field of
newly created blob to 4. This leads to changing fields data type for example
from the blob to the longblob if a temporary table is used.
The Item::make_string_field() function always converts Field_string objects
to Field_varstring objects. This leads to changing data type from the
char/binary to varchar/varbinary.
Added appropriate Field_timestamp object constructor for using in the
Item::tmp_table_field_from_field_type() function.
Added Field_blob object constructor which sets pack length according to
max_length argument.
The Item::tmp_table_field_from_field_type() function now creates
Field_timestamp object for a timestamp field.
The Item_type_holder::display_length() now returns correct NULL length NULL
length.
The Item::make_string_field() function now doesn't change Field_string to
Field_varstring in the case of Item_type_holder.

Bug#17294 - INSERT DELAYED puting an \n before data
Bug#16611 - INSERT DELAYED corrupts data
Bug#13707 - Server crash with INSERT DELAYED on MyISAM table
Combined as Bug#16218.
INSERT DELAYED crashed in 5.0 on a table with a varchar that
could be NULL and was created pre-5.0 (Bugs 16218 and 13707).
INSERT DELAYED corrupted data in 5.0 on a table with varchar
fields that was created pre-5.0 (Bugs 17294 and 16611).
In case of INSERT DELAYED the open table is copied from the
delayed insert thread to be able to create a record for the
queue. When copying the fields, a method was used that did
convert old varchar to new varchar fields and did not set up
some pointers into the record buffer of the table.
The field conversion was guilty for the misinterpretation of
the record contents by the delayed insert thread. The wrong
pointer setup was guilty for the crashes.
For Bug 13707 (Server crash with INSERT DELAYED on MyISAM table)
I fixed the above mentioned method to set up one of the pointers.
For Bug 16218 I set up the other pointers too.
But when looking at the corruptions I got aware that converting
the field type was totally wrong for INSERT DELAYED. The copied
table is used to create a record that is to be sent to the
delayed insert thread. Of course it can interpret the record
correctly only if all field types are the same in both table
objects.
So I revoked the fix for Bug 13707 and changed the new_field()
method so that it can suppress conversions.
No test case as this is a migration problem. One needs to
create a table with 4.x and use it with 5.x. I added two
test scripts to the bug report.

can lead to a wrong result.
All date/time functions has the STRING result type thus their results are
compared as strings. The string date representation allows a user to skip
some of leading zeros. This can lead to wrong comparison result if a date/time
function result is compared to such a string constant.
The idea behind this bug fix is to compare results of date/time functions
and data/time constants as ints, because that date/time representation is
more exact. To achieve this the agg_cmp_type() is changed to take in the
account that a date/time field or an date/time item should be compared
as ints.
This bug fix is partially back ported from 5.0.
The agg_cmp_type() function now accepts THD as one of parameters.
In addition, it now checks if a date/time field/function is present in the
list. If so, it tries to coerce all constants to INT to make date/time
comparison return correct result. The field for the constant coercion is
taken from the Item_field or constructed from the Item_func. In latter case
the constructed field will be freed after conversion of all constant items.
Otherwise the result is same as before - aggregated with help of the
item_cmp_type() function.
From the Item_func_between::fix_length_and_dec() function removed the part
which was converting date/time constants to int if possible. Now this is
done by the agg_cmp_type() function.
The new function result_as_longlong() is added to the Item class.
It indicates that the item is a date/time item and result of it can be
compared as int. Such items are date/time fields/functions.
Correct val_int() methods are implemented for classes Item_date_typecast,
Item_func_makedate, Item_time_typecast, Item_datetime_typecast. All these
classes are derived from Item_str_func and Item_str_func::val_int() converts
its string value to int without regard to the date/time type of these items.
Arg_comparator::set_compare_func() and Arg_comparator::set_cmp_func()
functions are changed to substitute result type of an item with the INT_RESULT
if the item is a date/time item and another item is a constant. This is done
to get a correct result of comparisons like date_time_function() = string_constant.
mysql-test/r/cast.result:
Fixed wrong test case result after bug fix#16377.
sql/item_timefunc.h:
Fixed bug#16377: result of DATE/TIME functions were compared as strings which
can lead to a wrong result.
The result_as_longlong() function is set to return TRUE for these classes:
Item_date, Item_date_func, Item_func_curtime, Item_func_sec_to_time,
Item_date_typecast, Item_time_typecast, Item_datetime_typecast,
Item_func_makedate.

Arg_comparator::set_compare_func() and Arg_comparator::set_cmp_func()
functions are changed to substitute result type of an item with the INT_RESULT
if the item is a date/time item and another item is a constant.
sql/field.cc:
Fixed bug#16377: result of DATE/TIME functions were compared as strings which
can lead to a wrong result.
Field::set_warning(), Field::set_datetime_warning() now use current_thd to get thd if table isn't set.
sql/item_cmpfunc.cc:
Fixed bug#16377: result of DATE/TIME functions were compared as strings which
can lead to a wrong result.
The agg_cmp_type() function now accepts THD as one of parameters.
In addition, it now checks if a date/time field/function is present in the
list. If so, it tries to coerce all constants to INT to make date/time
comparison return correct result. The field for the constant coercion is
taken from the Item_field or constructed from the Item_func. In latter case
the constructed field will be freed after conversion of all constant items.
Otherwise the result is same as before - aggregated with help of the
item_cmp_type() function.

Fixed compiler warnings
Fixed valgrind warning in Item_date_add_intervall::eq. (Recoding of bugfix #19490)
sql/field.cc:

sql/item.h:
Removed compiler warnings
sql/item_timefunc.cc:
Fixed Item_date_add_intervall::eq
The problem was that when we call 'eq' 'this' is not fixed, which means we can't call const_item() or a value function.
I fixed this so that we check eq for all arguments and that the sign and type are identical.
(The original code gave a 'accessing uninitialized data' in valgrind.
sql/mysql_priv.h:

When a CREATE TABLE command created a table from a materialized
view id does not inherit default values from the underlying table.
Moreover the temporary table used for the view materialization
does not inherit those default values.
In the case when the underlying table contained ENUM fields it caused
misleading error messages. In other cases the created table contained
wrong default values.
The code was modified to ensure inheritance of default values for
materialized views.

sql/field.h:
Fix Field_bit::field_length to store the correct value, adding
Field_bit::bytes_in_rec to remember the number of bytes used for
storing the value. Remove Field_bit_as_char::create_length, as it
is now redundant.
sql/ha_ndbcluster.cc:
Handle field_length of Field_bit actually being the display width (# of bits).

column is increasing when table is recreated with PS/SP":
make use of create_field::char_length more consistent in the code.
Reinit create_field::length from create_field::char_length
for every execution of a prepared statement (actually fixes the
bug).
mysql-test/r/ps.result:
Test results fixed (Bug#13134)
mysql-test/t/ps.test:
A test case for Bug#13134 "Length of VARCHAR() utf8 column is
increasing when table is recreated with PS/SP"
sql/field.cc:
Move initialization of create_field::char_length to the constructor
of create_field.
sql/field.h:
Rename chars_length to char_length (to be consistent with
how this term is used throughout the rest of the code).
sql/sql_parse.cc:
Initialize char_length in add_field_to_list. This function
effectively works as another create_field constructor.
sql/sql_table.cc:
Reinit length from char_length for every field in
mysql_prepare_table. This is not needed if we're executing
a statement for the first time, however, at subsequent executions
length contains the number of bytes, not characters (as it's expected
to).
The bug appears after implementation of WL#2984
(Make stored routine variables work according to the standard).
mysql-test/r/type_varchar.result:
Update result file.
mysql-test/t/type_varchar.test:
Add a test for BUG#15588.
sql/field.cc:
- use memmove() instead of memcpy() -- after implementation of WL#2984
(Make stored routine variables work according to the standard) it is
possible to store in the field the value from this field. For instance,
this can happen for the following statement:
SET sp_var = SUBSTR(sp_var, 1, 3);
sql/sp_head.cc:
- Work correctly with String:
- String length has to be be reset before use;
- qs_append() does not allocate memory, so the memory should
be reserved beforehand.
sql/sql_select.cc:
Polishing: should have been done in WL#2984.
