A new resolution diagnostic UnsuccessfulCallableReferenceAtom is
introduced that is used in EagerResolveOfCallableReferences.
No diagnostic is reported on unresolved calls with this diagnostic
because
#KT-59856
Previously, when a candidate was found with an applicability that is
better than the current best applicability, all previous candidates were
thrown away. Now we keep them, unless the new applicability is
successful. If no successful candidates are found, we fully resolve all
the unsuccessful ones and select the ones with the least bad
applicability. This improves diagnostics for unresolved calls.
#KT-57844 Fixed
Beside some corner cases, it's already prohibited in K1 because
adaptation have a bit strange nature
(they don't represent any existing real function exactly)
^KT-55137 Fixed
* Change 1.6 to 1.7 constants
* Fix SAFE_CALL_WILL_CHANGE_NULLABILITY for testData
* Change EXPOSED_PROPERTY_TYPE_IN_CONSTRUCTOR_WARNING to EXPOSED_PROPERTY_TYPE_IN_CONSTRUCTOR_ERROR
* Change NON_EXHAUSTIVE_WHEN_STATEMENT to NO_ELSE_IN_WHEN
* Fix testData for SafeCallsAreAlwaysNullable
* Change T -> T & Any in test dumps
* Change INVALID_CHARACTERS_NATIVE_WARNING -> INVALID_CHARACTERS_NATIVE_ERROR
* TYPECHECKER_HAS_RUN_INTO_RECURSIVE_PROBLEM_WARNING -> TYPECHECKER_HAS_RUN_INTO_RECURSIVE_PROBLEM_ERROR
This commit adds diagnostics for the following
* DELEGATE_SPECIAL_FUNCTION_MISSING
* DELEGATE_SPECIAL_FUNCTION_AMBIGUITY
* DELEGATE_SPECIAL_FUNCTION_NONE_APPLICABLE
Specifically, the report the following 4 errors.
* NON_VARARG_SPREAD
* ARGUMENT_PASSED_TWICE
* TOO_MANY_ARGUMENTS
* NO_VALUE_FOR_PARAMETER
Also added/updated the following position strategies.
* NAME_OF_NAMED_ARGUMENT
* VALUE_ARGUMENTS
Currently if there is an error in a function call, FIR would report the
entire expression if this call is qualified, but *only* the name if it's
not qualified. For example, assume the following two calls are all
contains some errors.
```
a.foo(1,2,3)
^^^^^^^^^^^^
bar(1,2,3)
^^^
```
The entire call of `foo` is reported since it's qualified. But only the
reference `bar` is reported since it's not qualified. This limits the
usage of position strategies because the IDE does not allow position
strategies to go outside of the initially reported PSI element
(org.jetbrains.kotlin.idea.fir.highlighter.KotlinHighLevelDiagnosticHighlightingPass#addDiagnostic).
This change passes both the original error named reference and the
surrounding qualified access expression and defer the decision of which
to use to the reporting logic.
For unresolved reference and checks on `super` keyword, the position
strategy should not highlight the surrounding parentheses. Hence a new
position strategy `REFERENCED_NAME_BY_QUALIFIED` is added.
In addition, this change also has the following side effect
* some diagnostics are no longer reported when there is a syntax error
since the higher level structure does not exist when there is a syntax
error
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.
This commit includes a lot of minor changes in testdata: new infrastructure
requires that each test file in one testdata file in one module must
have unique name, but a lot of existing spec tests didn't satisfy
this requirement
In FIR, the source of FirFunctionCall is set to call's selector.
In practice, sometimes (e.g. for DEBUG_INFO_CALL)
we expect the selector as the source,
and sometimes (e.g. for DEBUG_INFO_EXPRESSION_TYPE)
we expect the whole qualified call as the source.
Also, some diagnostics, like REDUNDANT_CALL_OF_CONVERSION_METHOD,
are expected to be reported on a selector, not on a whole call.
At this moment we ignore the problem & just don't support
DEBUG_INFO_EXPRESSION_TYPE for qualified calls.
