allows to compile only parts of the source files, denoted by top-level
"sections" (function with lambda param calls), but preserving original
file line/column numbers for easier diagnostics. Allow e.g. to compile
gradle "buildscript" section without preprocessing original file in
advance. See tests for examples.
Some IDE features relates onto that same descriptors will remain same
between resolve calls
Fix it to be true for TypeAliasConstructorDescriptor's
#KT-16265 fixed
Consider this code:
object Delegate {
operator fun getValue(t: Any?, p: KProperty<*>): String {
return ""
}
}
class A {
val String.ext by Delegate
}
then the type of <p> is KProperty2 (it has 2 receivers).
Test fix + review fixes
The problem was that when resolving super-calls we used known substitutor
when creating a type alias constructor, thus its original return itself,
while it's expected that it should return the descriptor before substitution
The main idea of the fix that `createIfAvailable` should always return
unsubstituted constructor.
Note that known substitutor for type alias constructor should be based
on abbreviation.
The test change seems to be correct as PROJECTION_IN_IMMEDIATE_ARGUMENT_TO_SUPERTYPE
is already reported.
Beside this, resolution behavior isn't expected to be changed dramatically
See how we translate raw types to Kotlin model:
RawType(A) = A<ErasedUpperBound(T1), ...>
ErasedUpperBound(T : G<t>) = G<*> // UpperBound(T) is a type G<t> with arguments
ErasedUpperBound(T : A) = A // UpperBound(T) is a type A without arguments
ErasedUpperBound(T : F) = UpperBound(F) // UB(T) is another type parameter F
Stack overflow happens with the following classes:
class A<X extends B> // NB: raw type B in upper bound
class B<Y extends A> // NB: raw type A in upper bound
when calculating raw type for A, we start calculate ErasedUpperBound(Y),
thus starting calculating raw type for B => ErasedUpperBound(X) => RawType(A),
so we have SOE here.
The problem is that we calculating the arguments for these raw types eagerly,
while from the definition of ErasedUpperBound(Y) we only need a type constructor
of raw type B (and the number of parameters), we don't use its arguments.
The solution is to make arguments calculating for raw types lazy

When synthetic member comes not from the receiver type itself,
but from one of its supertypes it doesn't make sense to subsitute
the member with receiver type, we should obtain relevant supertype
and use it instead.
#KT-16578 Fixed
When there is unsuccessful (e.g invisible) result of one kind (static/non-static)
and there is a successful candidate for another kind, choose the latter one.
Note, that we have to postpone commiting trace until we choose one of the results,
otherwise errors of unsuccessful results are reported
TODO: Maybe it makes sense to report all results when all of them are
unsuccessful (NONE_APPLICABLE or something like this)
#KT-16278 Fixed
To prevent tests from altering outcomes of the subsequent tests.
Also expose the clearCaches method (in the internal class
ReflectionFactoryImpl) so that it can be used in other places in similar
circumstances
Previously ReflectionTypes.find returned an error class in case a class
is not found in the module dependencies. The problem with this approach
is that each call site should call ErrorUtils.isError on the result and
report an error if needed, in order to stop this type from reaching the
codegen, which can't handle error types.
Now we create a MockClassDescriptor instance instead. It's not an error
class, so it'll be handled correctly in the codegen. Also its scope is
empty and errors are reported on any non-trivial usage (see
MissingDependencyClassChecker), so this approach is not worse than error
classes
#KT-16484 Fixed
Notes: if arity == 0, it means that type was `suspend () -> String` => arguments.size == 1, and it means that SuspendFunction0 has only one type argument and it is return type.
The problem was that in `Function<T>.apply(T)` T is now not-platform,
so when checking if not-null assertion is needed for parameter in SAM,
it's defined by the upper bounds of T that is a platform (Any..Any?),
and while it's definitely not marked as nullable it's still nullable
in a sense that it can contain null as a value.
So the solution is obvious
#KT-16413 Fixed
In most of the cases it was used together with CLASS_ONLY and vice versa
They only case when CLASS_ONLY was used without INNER_CLASS
is possibleParentTargetMap.COMPANION_KEYWORD.
But after diagnostic NESTED_OBJECT_NOT_ALLOWED has been introduced,
there's no sense in the restriction of exactly the companion's parent
