The failing assertion was written with the assumption that a NULL
string can never be passed to my_strtod(). However, an empty string
may be passed under some circumstances by passing str == NULL and
*end == NULL.
Fixed the assertion to take the above case into account.
All numeric operators and functions on integer, floating point
and DECIMAL values now throw an 'out of range' error rather
than returning an incorrect value or NULL, when the result is
out of supported range for the corresponding data type.
Some test cases in the test suite had to be updated
accordingly either because the test case itself relied on a
value returned in case of a numeric overflow, or because a
numeric overflow was the root cause of the corresponding bugs.
The latter tests are no longer relevant, since the expressions
used to trigger the corresponding bugs are not valid anymore.
However, such test cases have been adjusted and kept "for the
record".
When add an aliase name after NAME_CONST, the aliase name will be overwrite.
NAME_CONST will re-set the field's name only if there isn't an aliase in the
function fix-fields().
If there is an aliase, NAME_CONST doesn't re-set the field's name and keeps the old
name.
Problem: some queries using NAME_CONST(.. COLLATE ...)
lead to server crash due to failed type cast.
Fix: return the underlying item's type in case of
NAME_CONST(.. COLLATE ...) to avoid wrong casting.
offset for time part in UUIDs was 1/1000 of what it
should be. In other words, offset was off.
Also handle the case where we count into the future
when several UUIDs are generated in one "tick", and
then the next call is late enough for us to unwind
some but not all of those borrowed ticks.
Lastly, handle the case where we keep borrowing and
borrowing until the tick-counter overflows by also
changing into a new "numberspace" by creating a new
random suffix.

Fix for this bug and additional improvements/fixes
In detail:
- Remove unicode attribute from several columns
(unicode properties were nowhere needed/tested)
of the table tb3
-> The runnability of these tests depends no more on
the availibility of some optional collations.
- Use a table tb3 with the same layout for all
engines to be tested and unify the engine name
within the protocols.
-> <engine>_trig_<abc>.result have the same content
- Do not load data into tb3 if these rows have no
impact on result sets
- Add tests for NDB (they exist already in 5.1)
- "--replace_result" at various places because
NDB variants of tests failed with "random" row
order in results
This fixes a till now unknown weakness within the
funcs_1 NDB tests existing in 5.1 and 6.0
- Fix the expected result of ndb_trig_1011ext
which suffered from Bug 32656
+ disable this test
- funcs_1 could be executed with the mysql-test-run.pl
option "--reorder", which saves some runtime by
optimizing server restarts.
Runtimes on tmpfs (one attempt only):
with reorder 132 seconds
without reorder 183 seconds
- Adjust two "check" statements within func_misc.test
which were incorrect (We had one run with result set
difference though the server worked good.)
- minor fixes in comments
Upmerge of fix for this bug and a second similar problem
found during experimenting.
This replaces the first fix (already pushed to 5.1
and merged to 6.0) which
- failed in runs with the embedded server
- cannot be ported back to 5.0

NAME_CONST('whatever', -1) * MAX(whatever) bombed since -1 was
not seen as constant, but as FUNCTION_UNARY_MINUS(constant)
while we are at the same time pretending it was a basic const
item. This confused the aggregate handlers in exciting ways.
We now make NAME_CONST() behave more consistently.
breaks replication
NAME_CONST() didn't replicate constant character set and collation
correctly.
With this fix NAME_CONST() inherits collation from the value argument.
Both arguments of the function NAME_CONST must be constant expressions.
This constraint is checked in the Item_name_const::fix_fields method.
Yet if the argument of the function was not a constant expression no
error message was reported. As a result the client hanged waiting for a
response.
Now the function Item_name_const::fix_fields reports an error message
when any of the additional context conditions imposed on the function
NAME_CONST is not satisfied.
PS-protocol data is stored in different format - the MYSQL_RECORDS->data
contains the link to the record content, not to array of the links to
the field's contents. So we have to handle it separately for
embedded-server query cache.
Problem: passing a non-constant name to the NAME_CONST function results in a crash.
Fix: check the NAME_CONST name argument; return fake item type if we got
non-constant argument(s).
Problem: lying to the optimizer that a function (Item_func_inet_ntoa)
cannot return NULL values leads to unexpected results (in the case group
keys creation/comparison is broken).
Fix: Item_func_inet_ntoa::maybe_null should be set properly.
The NAME_CONST function is required to work correctly with constants only.
When executed with functions that return types other than those returned by
Item::field_type (string, int, decimal, or real), the result gets cast to
one of those types. This cannot happen for constants.
Fixed by only allowing constants as arguments to NAME_CONST.

This pads the value of CHAR columns with spaces up to full column length (according to ANSI)
It's not makde part of oracle or ansi mode yet, as this would cause a notable behaviour change.
Added uuid_short(), a generator for increasing 'unique' longlong integers (8 bytes)
results)
Before this fix, the function BENCHMARK() would fail to evaluate expressions
like "(select avg(a) from t1)" in debug builds (with an assert),
or would report a time of zero in non debug builds.
The root cause is that evaluation of DECIMAL_RESULT expressions was not
supported in Item_func_benchmark::val_int().
This has been fixed by this change.
