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)
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.
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
#KT-36247 fixed
A lot of testdata changed because significanly less (error) descriptors
are created for unresolved types, so diagnostics became different.
- locals win
- unary calls to plus/minus are not supported in favor of unaryPlus/unaryMinus
- unqualified nested classes are temporarily reported as unresolved
- function without receiver win against extension function
- explicit import win against star import
