In MemberDeserializer.loadProperty, we incorrectly passed 0 to
getAnnotations when loading annotations on property accessors in case
the protobuf field getter_flags/setter_flags was not present. The
correct behavior, as described in metadata.proto, was to pass a special
"default accessor flags" value, constructed from the main property
flags. Otherwise in case there were annotations both on the property and
on the accessor (as in PropertyAndAccessor.kt) and the accessor was
otherwise default, we would assume that it had no annotations and would
not load them in compiler and reflection
#KT-25499 In Progress
<IMPL_SUFFIX> for method is a method signature hash,
if method value parameter types contain inline class types,
otherwise 'impl'.
Constructor methods are named as 'constructor-<IMPL_SUFFIX>'.
Synthesized 'box' and 'unbox' methods are named as
'<METHOD_NAME>-<IMPL_SUFFIX>'.
Erased implementations of overriding and non-overriding methods
are named as '<METHOD_NAME>-<IMPL_SUFFIX>'.
Fully specialized implementation of 'equals' will have a special suffix.
Minimize AnnotationsImpl to leave it usable in simple scenarios where
there's no use-site targeted annotations, and use TargetedAnnotations in
the only place in the frontend (AnnotationResolverImpl) where use-sites
were needed.
Also, delete kdoc on Annotations.isEmpty to prevent readers from putting
too much thought into how it works. With the exception of a few places
in the frontend where use-site targeted annotations are still accessed
via the Annotations object, it's now an implementation detail and users
(such as backends, IDE) should not care about them at all, and instead
should just deal with the correct element when processing annotations
After this commit, it's overridden only in AnnotationsImpl and
CompositeAnnotations.
Note that although FilteredAnnotations did have a non-trivial
implementation, that class was only used in circumstances where
annotations with use-site targets could not be of any use, so it's safe
to return empty list there now. One could argue that the new semantics
makes more sense: filter "standard" annotations, but don't touch those
with use-site targets because they are not applied to this element
directly, thus should likely not be affected by the filtering
Instead of returning the list of targeted annotations in
loadCallableAnnotations, add two separate methods to load annotations on
the backing field and on the delegate field of the property
Add PropertyDescriptor.backingField/delegateField to store annotations
on the field directly in an otherwise almost empty descriptor instance,
instead of storing them with use-sites in the corresponding property
descriptor. Instead of AnnotationWithTarget, create AnnotationDescriptor
instances in AnnotationSplitter. Change DescriptorRenderer to render
annotations on "related" declarations when needed, with the explicit
use-site target if applicable.
Most changes in diagnostic test data are related to the fact that
annotations which are known to have an incompatible use-site to the
declaration they're applied at (such as `@param:`-annotation on a
function), are now not loaded at all. It's fine because the code is
erroneous, so it doesn't really matter how do we load annotations with
invalid targets (some of this logic is also changed freely in subsequent
commits). Some changes are also explained by the fact that for example
an annotation on the property which is only applicable to FIELD is now
rendered with an explicit use-site target `@field:`, regardless of
whether it did have that use-site target syntactically or not.
Basically, after this change there's no point in calling
Annotations.getUseSiteTargetedAnnotations/getAllAnnotations anymore
because it's easier and more intuitive to just use Annotations of the
corresponding descriptor -- the backing / delegate field (introduced in
this commit) or the extension receiver / setter parameter (related
behavior was fixed in previous commits). Usages of
use-site-target-related methods will be refactored out in subsequent
commits
Make it possible to specify annotations of the setter parameter when
constructing the default setter via DescriptorFactory; pass the split
annotations in DescriptorResolver.resolvePropertySetterDescriptor
#KT-25500 Fixed
Note that this change brings an incompatibility: `Array<Foo>::class`
will be seen as `Foo::class` by the old deserializer. We consider this
OK because the compiler never had any logic that relied on reading class
literal arguments correctly (otherwise it wouldn't have worked because
it could only see `Array<*>::class` before this commit), and the support
of annotations on types in JVM reflection is only available in the
upcoming 1.3 release (KT-16795)
#KT-22069 Fixed
These three methods are conflicting with existing extensions,
thus the behavior might be changed when switching to JDK 11
Probably, it's worth revisiting our strategy here,
e.g. by blacklisting all new methods in
#KT-24974 Fixed
Suspend functions and callable references to suspend lambdas are already
supported.
Support callSuspendBy of suspend function of big arity.
#KT-24854: Fixed
Avoid name clashes in cases such as
inline class Login(val login: String)
inline class Password(val password: String)
fun validate(login: Login) { ... }
fun validate(password: Password) { ... }
This will make it possible to avoid raw types when inheriting from both
FunctionBase and Function<R>. This change adds a generic type parameter
to FunctionBase and Lambda which is not source-breaking under our policy
because both FunctionBase and Lambda are internal classes (located in
package kotlin.jvm.internal)
Add Char.MIN_VALUE and Char.MAX_VALUE implementations in primitive companion objects.
Update builtins test data and public API.

Set LATEST_STABLE language version and current version of stdlib to 1.3, set IS_PRE_RELEASE
Remove "EXPERIMENTAL" from 1.3 version description in tests and gradle options
In some tests with txt (probably all except loadJava), property
accessors are not rendered at all, so a third option value (NONE) will
be useful to determine whether we need to render annotations on property
accessors as get/set/sparam-targeted annotations on the property
Only use the other setType that takes an instance of
ReceiverParameterDescriptor. This will make sure that call sites can
use correct receiver annotations
This commit reverts 59e2101a25 partially,
leaving only the implementation of KT-25972 for JVM. The reason is that
we can't fully commit to stabilizing JS (and .kotlin_metadata) binary
metadata formats so much as to postpone any changes done to it for a
whole release year time. It's likely that we will need to update JS
metadata format incompatibly pretty soon, and with the scheme where we
can read the "current + 1" version, it'd require advancing the metadata
version by 2, which would break the nice property that the metadata
version (since Kotlin 1.4) is equal to the version of the compiler that
produced it.
