There was no way to return an error from the client library
if no MYSQL connections was established.
So here i added variables to store that king of errors and
made functions like mysql_error(NULL) to return these.

While the manual mentions FRAC_SECOND only for the TIMESTAMPADD()
function, it was also possible to use FRAC_SECOND with DATE_ADD(),
DATE_SUB() and +/- INTERVAL.

Fixed the parser to match the manual, i.e. using FRAC_SECOND for 
anything other than TIMESTAMPADD()/TIMESTAMPDIFF() now produces a 
syntax error.

Additionally, the patch allows MICROSECOND to be used in TIMESTAMPADD/
TIMESTAMPDIFF and marks FRAC_SECOND as deprecated.

Under some circumstances a combination of aggregate functions and
GROUP BY in a SELECT query over a VIEW could lead to incorrect
calculation of the result type of the aggregate function. This in
turn could result in incorrect results, or assertion failures on debug
builds.

Fixed by changing the logic in Item_sum_hybrid::fix_fields() so that
the argument's item is dereferenced before calling its type() method.

The test case for the bug#31048 checks that there is no crash on stack
overrun. But due to different stack sizes on different platforms it failed
on some of them.

The new test case check that a query with at least 4 level subquery nesting
works without the stack overrun nesting and other levels of nesting doesn't
cause a crash.

Finding a routine should be a transparent operation as

Problem is not about intervals and doesn't actually cause 'full table scan'.
We have an optimization for DISTINCT when we have
'DISTINCT field_from_first_join_table' we don't need to read all the
rows from the JOIN-ed table if we found one conforming row.
It stopped working in 5.0 as we return NESTED_LOOP_OK if we came upon
that case in the evaluate_join_record() and that doesn't break the
recordreading loop in sub_select().

Fixed by returning NESTED_LOOP_NO_MORE_ROWS in this case.

Zero fill is a field attribute only. So we can't always 
propagate  constants for zerofill fields : the values and 
expression results don't have that flag.

Fixed by converting the const value to a string and 
using that in const propagation when the context allows it. 
Disable const propagation for fields with ZEROFILL flag in
all the other cases.

                 for wildcard values.
The server ignored escape character before wildcards during
the calculation of priority values for sorting of a privilege
list. (Actually the server counted an escape character as an
ordinary wildcard like % or _). I.e. the table name template
with a wildcard character like 'tbl_1' had higher priority in
a privilege list than concrete table name without wildcards
like 'tbl\_1', and some privileges of 'tbl\_1' was hidden
by privileges for 'tbl_1'.

The get_sort function has been modified to ignore escaped
wildcards as usual.

  calculation.
  
  The get_sort function has been modified to ignore escaped wildcards
  and alone escapes like in the wild_case_compare function.

Instead of copying of whole character string from a temporary
buffer, the server copied a short-living pointer to that string
into a long-living structure. That has been fixed.

Under some circumstances a combination of VIEWs, subselects with outer
references and PS/SP/triggers could lead to use of uninitialized memory

Fixed by changing the code in Item_field::fix_fields() so that in cases
when the field is a VIEW reference, we first check whether the field
is also an outer reference, and mark it appropriately before returning.

  Fixed bug#15409.
  The Field_set::store(longlong nr,...) method incompletely
  calculates a bit mask for the comparison with a given number:
  if that number is greater than 0x7F00 0000 0000 0000 (LONGLONG_MAX),
  it uses zero bit mask instead of 0xFFFF FFFF FFFF FFFF (ULONGLONG_MAX).
  
  Incomplete expression has been replaced with a set_bits macro call.

The unsignedness of large integer user variables was not being
properly preserved when feeded to prepared statements. This was
happening because the unsigned flags wasn't being updated when
converting the user variable is converted to a parameter.

The solution is to copy the unsigned flag when converting the
user variable to a parameter and take the unsigned flag into
account when converting the integer to a string.
