types which have subtype constraint which constrains the field should be
forbidden</td>

<tr class="even print">
<td class="print-category">Description</td>
<td colspan="5" class="print">If you have a situation like this:<br />
<br />
type record Pair { integer i, integer j }<br />
type Pair AllowedPair ({1, 2}, {2, 3})<br />
<br />
function f() {<br />
  var AllowedPair x := {1, 2}<br />
  inc(x.i); // this should be an error<br />
}<br />
<br />
function inc(inout integer p) {<br />
  p := p + 1;<br />
}<br />
<br />
Then at runtime, this would lead to an invalid variable assignment to
variable x which is probably not checked at runtime (because
implementing this in general would mean that for every assignment all
the subtype constraints of all the containing variables need to be
checked) and thus can lead to problems.<br />
<br />
Therefore, I propose to disallow any use as lvalues of field references
constrained by a subtyping constraint of one of their ancestors, i.e. as
the target variable in an assignment or as an inout or out
parameter.<br />
<br />
That means that such constrained records always have to be assigned
in-bulk (by using structured value notations), at least for all the
fields that are constrained by the subtyping constraints of their
ancestors.<br />
If a field is not constrained by an ancestor's subtyping constraint, it
can still be normally used as lvalue.<br />
<br />
Example:<br />
<br />
type record R { integer k, integer i, integer j }<br />
type R R2 ({ k:= 1, i := 2}, { k:= 2, i := 3})<br />
<br />
function g() {<br />
  var R2 x := { 1, 2 }<br />
  x.k := 2; // error<br />
  inc(x.i); // error<br />
  inc(x.j); // allowed<br />
  x.j := 5; // allowed<br />
}<br />

<td class="print">I know that we talked about this, but... when
considering the issue, this would mean that constrained structured types
can be used to define constants and templates only...; I would say it is
quite rare that the user assignes values for the complete structured
variable only but never to its fields...; quite the opposite, structured
variables are commonly used to construct the value at runtime
step-by-step. So, the user will not be able to define parameterized
templates for the type, dynamic construction of values/templates would
be impossible, what about in parameters (disallowing inout and out only
would - again - create a very specific exception in the language) and
last but not least would also limit valid uses, when the value assigned
to a field is in line with the constraint of the type.<br />
This needs further consideration in the STF.<br />

Today it is possible and allowed to change just one field of a variable
based on such an imported ASN.1 type. But the point is, that a
limitation of this kind would be non-backward compatible.<br />

As we cannot agree on accepting the proposal, either we can agree on
closing the CR with not fixed as we escalate it to MTS.<br />

<td class="print">Maybe we should find out if any of the existing tools
are even aware of the problem and deal with it properly. I.e. it is very
easy to produce values that violate the restrictions even though this
can only be caught at runtime and only via quite complicated checking
(which I am almost sure no tool does).<br />
<br />
Since closing the CR would leave the problem thus unresolved, I think an
escalation to MTS would then be the way to go.<br />
<br />
As a compromise, we could, of course, at least (like we did for the
non-determinism of initializing templates) strongly advise against such
usages (as the potentially problematic places can be determined
statically) so that<br />
<br />
a) people become aware of the potential problem<br />
b) tools have an incentive to check for those situation</td>
