Bug#34749: Server crash when using NAME_CONST() with an aggregate function
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.
mysql-test/r/func_misc.result:
show that a combination of NAME_CONST('x', -y) and an aggregate
no longer crashes the server.
mysql-test/t/func_misc.test:
show that a combination of NAME_CONST('x', -y) and an aggregate
no longer crashes the server.
sql/ha_ndbcluster_cond.cc:
tell cluster about "new" function type NEG_FUNC.
(this was previous identified as UNKNOWN_FUNC,
so we just handle it the same way, that's all.)
sql/ha_ndbcluster_cond.h:
tell cluster about "new" function type NEG_FUNC.
(this was previous identified as UNKNOWN_FUNC,
so we just handle it the same way, that's all.)
sql/item.cc:
make NAME_CONST() transparent in that type() of
-constant is that of constant, not that of unary
minus (id est, FUNC_ITEM).
sql/item.h:
Move constructor to item.cc
sql/item_func.h:
Revert Bug#30832; we can apply the magic more narrowly
(just for NAME_CONST() rather than all Item_func_neg).
Introduce new function type "NEG_FUNC."

Bug #54461: crash with longblob and union or update with subquery
Queries may crash, if
1) the GREATEST or the LEAST function has a mixed list of
numeric and LONGBLOB arguments and
2) the result of such a function goes through an intermediate
temporary table.
An Item that references a LONGBLOB field has max_length of
UINT_MAX32 == (2^32 - 1).
The current implementation of GREATEST/LEAST returns REAL
result for a mixed list of numeric and string arguments (that
contradicts with the current documentation, this contradiction
was discussed and it was decided to update the documentation).
The max_length of such a function call was calculated as a
maximum of argument max_length values (i.e. UINT_MAX32).
That max_length value of UINT_MAX32 was used as a length for
the intermediate temporary table Field_double to hold
GREATEST/LEAST function result.
The Field_double::val_str() method call on that field
allocates a String value.
Since an allocation of String reserves an additional byte
for a zero-termination, the size of String buffer was
set to (UINT_MAX32 + 1), that caused an integer overflow:
actually, an empty buffer of size 0 was allocated.
An initialization of the "first" byte of that zero-size
buffer with '\0' caused a crash.
The Item_func_min_max::fix_length_and_dec() has been
modified to calculate max_length for the REAL result like
we do it for arithmetical operators.

The Field_double::val_str() method call on that field
allocates a String value.
Since an allocation of String reserves an additional byte
for a zero-termination, the size of String buffer was
set to (UINT_MAX32 + 1), that caused an integer overflow:
actually, an empty buffer of size 0 was allocated.
An initialization of the "first" byte of that zero-size
buffer with '\0' caused a crash.
The Item_func_min_max::fix_length_and_dec() has been
modified to calculate max_length for the REAL result like
we do it for arithmetical operators.
