Prevent stack overflow during uncapturing of star projection
for parameter with recursive upper bound.
Uncapture star projections for flexible type parameters with
respect to flexible upper bound.
^KT-35210 Fixed
With NO_LOCKS strategy we can easily end up in a situation when
constraint system for a generic call is built incorrectly,
producing flaky errors (or don't produce errors at all)
Now proper storage manager is injected for all cases except:
- IR
- Codegen
- Serialization plugin
- Fake local objects
Most likely, NO_LOCKS strategy for these cases is fine as at that point
the compiler works in one thread
#KT-34786 Fixed
Default type of LazySubstitutingClassDescriptor is not lazy. However, most of default types are,
and there is an optimization in KotlinTypeFactory, which uses default type for simple type without
type arguments and/or annotations. LazySubstitutingClassDescriptor's default type creates simple type
with factory, which may therefore cause recursion.
#KT-34029 Fixed
Before this commit, the substituted FunctionDescriptor didn't have a source element.
As a result, 'CodeFragmentParameterAnalyzer.isCodeFragmentDeclaration' failed to recognize such a descriptor as fragment-local, and it was erroneously captured.
Function return type can't and should not be used during overload resolution of callable references.
Since it can be DeferredType, its substitution in CS caused exception.
Disable annotation rendering in default type and descriptor renderers.
Preserve annotations in Android and Serialization plugins.
Update error texts in ide tests.
Nullability annotations in Java descriptors are rendered with context-dependent renderer.
#KT-20258 Fixed
If the delegated property operators involved are inline, and delegated
property metadata parameter is not used (which is often the case, e.g.,
'lazy'), we can skip those properties in metadata generation.
NOT implemented: special case when only 'kProperty.name' is used by the
corresponding delegated property operators.
Also a sneak fix for KT-34060.
The changes introduced 471134d31e are only needed
for the case of HMPP project while for other cases it might break the behavior
a bit like in KT-34027
See org.jetbrains.kotlin.resolve.calls.results.OverloadingConflictResolver#filterOutEquivalentCalls
Before 471134d we were comparing
"fun foo(x: String)" with "[substituted] fun foo(x: String)"
and areCallableDescriptorsEquivalent returned false for such case.
Thus, both overrides were left in the resulting set.
After 471134d, those two descriptors
becamed considered as equal thus having a possibility to remove any of them.
The problem is that "areCallableDescriptorsEquivalent" has kind of
unclear contract. Effectively it checks whether two descriptors match
to the same declaration
But straightforward fixing of this exact call-site (using original descriptors)
doesn't help: behavior might change in a very subtle way (see org.jetbrains.kotlin.spec.checkers.DiagnosticsTestSpecGenerated.NotLinked.Dfa.Pos#test72)
So, the main idea is changing the contract for areCallableDescriptorsEquivalent
only when project is HMPP one.
^KT-34027 In Progress
The actual problem was introduced in 4f1e85b468, note how `hashCode` is implemented:
```
var currentHashCode = cachedHashCode
if (currentHashCode == 0) return currentHashCode
...
```
It's a silly bug, there should be check `if (currentHashCode != 0) ...` because `0` is used a marker for "uncomputed value".
Now, in the commit 0219b86d06 I added map with `KotlinType` as a key and because of constant `hash` for `KotlinType`, we basically got `List` instead of `Map`, which caused this performance regression
#KT-34063 Fixed
Make ReifiedTypeInliner and related classes generic over the
KotlinTypeMarker subtype (KotlinType or IrType), add a typeSystem to get
arguments/nullability and other properties of types regardless of their
representation, but still fall back to KotlinType when generating the
actual bytecode of other intrinsics (as/is)
1) renderContextNearLocalVariable - if true renderer add fq name for local variables after "@" symbol
2) fullContextForLocalVariable - if true then renderer add all fq names for local variables, else only last one
3) useBaseClassAsReceiver - if true then renderer uses dispatch receiver as extension receiver if the last is null
Otherwise StackOverflowError or recursion-detection in LockBasedStorageManager
may happen
It's fine to have non-refined type there because it only can affect
content of containing type member scope that should be refined after
being requested
There was an issue that `KotlinType.equals` called in `KotlinTypeFactory.flexibleType`
and `RawType` constructor produced endless recursion of types that wasn't
computed yet
Effectively, this commit allows for common module
to see internal content of all expect-modules
The problem is that when computing the member scope for A (see the test)
we're building a special member scope for CommonAbstract viewed from JVM
and it's effectively has a fake override of actual member from Jvm/ExpectBase.
OverridingUtil checks if it's visible in CommonAbstract and finds that it's not
thus creating a fake_invisible fake override
The latter results in A::foo override being marked as INVISIBLE_MEMBER_OVERRIDE
Probably, the fix might be smarter
(passing a requested module to OverridingUtil::createAndBindFakeOverride)
but allowing using internal member seems to be safe & simple
because it's reasonable to assume there's no cyclic dependencies
between expected/actual modules
Before types refinement has been introduced it was reasonable to assume
that whenever we have two callables in the same declaration
they are actually different
But it become false once types refinement were introduced
and the same declarations may appear as different descriptors' instances
when viewing from different modules
The change does look very fragile because in many cases
source element is NO_SOURCE
At the same time, declaring actually different members
with the same signature is prohibited and may make sense only
in case of source-based members
Otherwise, it results in skipping refinement for JobNode when requested
from JVM module while it's necessary because CompletionHandlerBase's content
depends on the module
