* 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
We are going to deprecate `WITH_RUNTIME` directive. The main reason
behind this change is that `WITH_STDLIB` directive better describes
its meaning, specifically it will add kotlin stdlib to test's classpath.
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
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.
It might be necessary for cases like
run @l1{
run {
if (...) return@l1 1
}
}
"if" is a synthetic call, but without candidate since there's just one branch
But return@l1 1 is incomplete because it's resolved in dependent context
and "1" is hang incomplete integer literal
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
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`, `_`)
Repeat the logic of KotlinConstraintSystemCompleter in ConstraintSystemCompleter.
Implement additional context operations required for updated lambda completion algorithm.
Helps fixing to more specific type in the following situations:
Type1 <: Var1
Var2 <: Var1
Var2 <: Type2
Type1 and Type2 may also be nullable and non-nullable versions of the same type.
Note that no additional constraints can be inferred from such constraints before fixation.
Resulting types for variables will always Type1 and Type2 may also be nullable and non-nullable versions of the same type.
Fixing Var1 first will make Var2's type more specific while fixing Var2 first
will make Var1's type less specific. The first is preferrable in general.
Use known type parameters substitutor after substitutor for fresh variables.
The old logic of substituions had the following order:
- replace known type parameters
- replace type parameters with type variables
- complete inference
- replace type variables with inferred types
According to the updated logic, replacement goes as follows:
- replace type parameters with type variables
- replace known type parameters; if they were variables, this will effectively remove them from inference
- complete inference
- replace remaining type variables with inferred types
Support projection substitution in new type substitutor.
It is needed for correct interaction with old type substitutor.
Old type substitutors can contain mappings constructor -> projection
which couldn't be expressed correctly with existing substitutor API in some cases.
