Nested classes which are not inner class should not be able to access
type parameters of the outer class. Make sure access is not available
when resolving super types.
#KT-54748 Fixed
This directive anyway does not make test run twice with OI, and with NI
It only once run the test with specific settings (// LANGUAGE)
and ignores irrelevant (OI or NI tags)
To do so, inside the root cause of inapplicable candidate errors,
we will record expected/actual type of receiver, if any.
That will help identifying inapplicable calls on nullable receiver.
Update includes:
- Changing syntax of `OI/`NI` tags from `<!NI;TAG!>` to `<!TAG{NI}!>`
- Fix some incorrect directives
- Change order of diagnostics in some places
- Remove ignored diagnostics from FIR test data (previously `DIAGNOSTICS` didn't work)
- Update FIR dumps in some places and add `FIR_IDENTICAL` if needed
- Replace all JAVAC_SKIP with SKIP_JAVAC directive
This commit introduces several different things, in particular:
- check type arguments in expressions
- new TypeArgumentList node to deal with diagnostic source
- ConeDiagnostic was moved to fir:cones
- ConeIntermediateDiagnostic to use in inference (?) without reporting
- detailed diagnostics on error type
In 1.3, due to changes in language, testdata for some tests can be
different from 1.2
We want to simlultaneously test both versions, so instead of fixing
language version in such tests, we split them into two: one with fixed
1.2, another with fixed 1.3
Introdude deprecation as per KT-21515. Warning is reported on type
usage, that soon will became invisible. Quickfix by adding explicit
import is added.
Idea behind implementation is to mark scopes that are deprecated (see
ClassResolutionScopesSupport).
Then, during walk along hierarchy of scopes, look at deprecation status
of the scope that has provided this classifier.
Note that we also have to check if there are *some* non-deprecated
visibility paths (because we can see classifier by two paths, e.g. if
we've added explicit import) -- then this type reference shouldn't be
treated as deprecated.
1. Substitution variance (sv) is a substitution composition of type alias argument variance (av)
and corresponding expanding type argument variance (ev):
sv =
| av == ev -> av
| av == INVARIANT -> ev
| ev == INVARIANT -> av
| else -> (variance conflict error; av)
2. Resulting variance (rv) is a type argument composition of sv and type parameter variance (pv):
rv =
| sv == tv => INVARIANT
| sv == INVARIANT => INVARIANT
| tv == INVARIANT => sv
| else -> (variance conflict error; sv)
When resolving arguments on inner classifier, one can omit the arguments
for outer class 'Outer' if they are present implicitly in the scope:
- One of the supertypes of current class is Outer
- One of the outer classes or one of their supertypes is Outer
Relevant arguments are obtained from the first type found by
the algorithm above
Note that before this commit implicit arguments were only been searched
in containing classes
