This commit addresses the following issues:
* accessors didn't take into account their property's receiver type,
which caused NoSuchMethod due to signature mismatch. Now the property's
receiver type is passed to Fir2Ir translation of accessors.
* property's parent was not class, e.g., kotlin.collections.indices.
Now the symbol table collects WrappedPropertyDescriptorWithContainerSource
besides WrappedFunctionDescriptorWithContainerSource, so that
facade classes for such properties can be generated before codegen.
* accessor's parent was not class. Now the containerSource of
the property descriptor is passed to accessor descriptor.
Library methods such as 'listOf' are resolved
to have the package fragments as their parents,
but JVM expects their containing file classes as parents.
This fix generates those file classes and
uses them as parent replacements for such library methods.
where "fix" means "work around a bug that is much harder to fix". When
lambdas are extracted into the nearest class, captured type parameters
are not transformed into type parameters of the new method; because of
this, to check whether a reified type parameter is captured by a method
we need to check the outermost named function, not the current function.
Most of these tests used this directive as a way to opt in to a new
language feature, and most of those features are already stable for a
long time, so no opt-in is needed. Some other tests used the directive
to opt out from a language feature, replace those by the `LANGUAGE`
directive. One test used the directive to test behavior that actually
depended on the API version; use `API_VERSION` directive there instead.
* Move FinallyBlockLowering to common part
* Fix catching of dynamic exception
* Fix bridges for suspend functions
* Disable explicit cast to Unit
* Run lowering per module
* Update some test data
This commit support the following case.
Suppose we have such declaration:
fun <T> foo(): T { ... }
Then in code we want to use it like this: `foo() as String`.
But in LV <= 1.1 we have type inference error: "Not enough
information for type parameter `T`". This error happened because we
do not use type from cast as expected type for call.
In this commit we fix this problem and use this type as expected type
in following cases:
- our function has only one type parameter (this can be relaxed later)
- function parameter types and extension receiver type not contains `T`
Also this fix problem with `findViewById`.
Already signature was: `fun findViewById(...): View`
and was used like: `findViewById() as MyView`.
New signature is `fun <T : View> findViewById(...): T`
and old usage was broken because of problem described above
This patch mutes the following test categories:
* Tests with java dependencies (System class,
java stdlib, jvm-oriented annotations etc).
* Coroutines tests.
* Reflection tests.
* Tests with an inheritance from the standard
collections.
See doNotCaptureSupertype test for clarification:
When resolving b.collect(toList()) we're building a common system with
two variables T and R.
The problem was that when introducing the constraint
C<T, Inv<T>> <: C<in String, R> we then were seeing the constraint
T <= in String, and add the constaint T=Captured(in String)
That lead to R=Inv<T>=Inv<Captured(in String)>, and after approximation
R=Inv<in String>, that is not the desirable result (Inv<String> suits here)
But the root problem was that we add captured constaint when projection was from supertype,
that seems to be wrong, and for example Java doesn't do that in the similar situation.
