Previously helpers from checkType.kt was in special package, and
if directive was enabled then test runner (`AbstractDiagnosticTest`)
injected additional imports to test files and removed them after test
was completed.
It's very hard to support such behavior in new test infrastructure so
there was a decision about changing `CHECK_TYPE`:
1. All helpers from `checkType.kt` now stays in default package
2. `CHECK_TYPE` only adds `checkType.kt` to set of analyzed files
and don't modify their content
For test which are written in default package (most of tests actually)
there are no changes. On the other hand if there is a test where dev
want to use checkType functions in testfile with some package then he
should explicitly import functions which he needed (`checkSubtype`,
`checkType`, `_`)
This commit includes three changes:
1. 'EnhancedNullability' is no more set for declaration types
2. It is no more used for conversion types in translator
3. Translator inserts implicit not-null cast only when enhanced type is cast to not-null type.
In init block or property initializers,
for `val x` declared in primary constructor,
`x` reference is now resolved to property, not to parameter.
So we need two different scopes for primary constructor,
one for 'pure' parameters and another one for all parameters,
including val/var ones.
#KT-42844 Fixed
This commit is workaround for cases like
MyJavaMap<KK : Bound, V> : java.util.Map<K, V>.
After signature changing and substitution we have
MyJavaMap.get(Object) declared and MyJavaMap.get(KK) from supertype,
which can't be otherwise matched as overriding one another.
There is introduced algorithm of resolution with jumps: before
resolution of some class we resolve all status of members of its
supertypes, so we can properly determine inherited visibility
and modifiers
Several tests are affected by the usage of fixation direction calculator in FIR.
Restored to mimimize test data changes.
It is unnecessary in FE10 because a type variable with unknown type
is inferred into an error type, but affects test data in FIR where
Nothing/Any is selected by direction (as a temporary measure).
CR candidate in spec test is Unresolved in FIR because top-level CRs are resolved as call arguments.
Resolution ambiguity is also present in FE10 when CR is wrapped into an id call.
Repeat the logic of KotlinConstraintSystemCompleter in ConstraintSystemCompleter.
Implement additional context operations required for updated lambda completion algorithm.
