- do not allow it to be used together with JvmMultifileClass (otherwise
implementation becomes complex)
- do not allow to declare classes in a JvmPackageName-annotated file
(similarly, the implementation of this would be much harder in the
compiler, and there would need to be special support in the IDE)
- check that the value is a valid FQ name
- do not allow root package just in case
The main changes are in jvm_package_table.proto and ModuleMapping.kt.
With JvmPackageName, package parts can now have a JVM package name that
differs from their Kotlin name. So, in addition to the old package parts
which were stored as short names + short name of multifile facade (we
can't change this because of compatibility with old compilers), we now
store separately those package parts, which have a different JVM package
name. The format is optimized to avoid storing any package name more
than once as a string.
Another notable change is in KotlinCliJavaFileManagerImpl, where we now
load .kotlin_module files when determining whether or not a package
exists. Before this change, no PsiPackage (and thus, no JavaPackage and
eventually, no LazyJavaPackageFragment) was created unless there was at
least one file in the corresponding directory. Now we also create
packages if they are "mapped" to other JVM packages, i.e. if all package
parts in them have been annotated with JvmPackageName.
Most of the other changes are refactorings to allow internal names of
package parts/multifile classes where previously there were only short
names.
This annotation is currently internal because we only commit to its
support for our own libraries. It will be used to change JVM package
names of declarations in JDK-specific stdlib additions (now called
kotlin-stdlib-jre7/8), both to preserve source compatibility of the old
Kotlin code and to solve the split package problem (KT-19258)
Search abstract members in unsubstituted scope to avoid computation
of substituted descriptors for each type (effectively for each SAM call)

It might be helpful for performance as these methods are called
for each resolution candidate and in the same time they scan
the whole overridden tree of a callable member
- Tell user what exactly is not supported (e.g., local inline function)
- Reduce diagnostics range to a keyword or an identifier
where appropriate
#KT-16223 Fixed Target versions 1.1.50
In Kotlin 1.1 and before, there were no nullability assertions on
extension receivers, because receiver is resolved with NO_EXPECTED_TYPE.
So, if an expression of platform type is passed as an extension receiver
to a non-private function, it would fail with IllegalArgumentException.
However, if the function is private, then we generated no parameter
assertions under assumption that such function can be called from Kotlin
only, and all arguments are checked on the call site. Thus 'null' could
propagate indefinitely.
In Kotlin 1.2, we do the following:
- Generate nullability assertions for expression receivers.
NB nullability assertions are stored for ReceiverValue instances, not
for expressions: given expression can act as receiver in different
calls, each with an expected receiver type of its own.
- Generate nullability assertions for extension receivers of private
operator functions.
NB it still can throw NPE for some particular "optimized" cases, but at
least those nulls would not propagate indefinitely.
This behavior is disabled by an "advanced" command-line option
'-Xno-receiver-assertions'.
Rename addDeclarations -> registerModuleComponents
Use it to provide SamWithReceiverResolver extensions instead
Post construction on container composition can be achieved
but manually inserting injections where it seems appropriate
is bug prone
This fixes a bug where SamWithReceiverPlugin extension was not registered
for some containers in IDE which led to incorrect highlighting in IDE
Add IDE test for applying SamWithReceiver plugin
#KT-18062 Fixed
This way is more flexible for example for tests, where configuring the
service implementation may be tricky (it's usually done in
KotlinCoreEnvironment in production code)
* Support flags with any value (not just Boolean)
* Support all flags by parsing arguments in KotlinFacetSettings, instead
of manually listing known flags
#KT-19210 Fixed
The error message is removed and is replaced with a code that adapts
inline suspend functions produced by the old compiler with the
suspension markers that new compiler expects.
Also report the "named does not read unnamed" error, which was not
possible previously because we wouldn't be able to read anything from
kotlin-stdlib (because it was added to the unnamed module by default)
Essentially, the logic that was previously in
JvmModuleAccessibilityChecker.diagnosticFor, is moved into a new
abstract method JavaModuleResolver.checkAccessibility, which is
implemented differently in the compiler and in the IDE. In the compiler,
we use our JavaModuleInfo and JavaModuleGraph, as previously. In the
IDE, we use intellij's PsiJavaModule and JavaModuleGraphUtil.
This fixes strange behavior in IDE where some modules could be observed
in an invalid state. The cause of that was the JavaModuleGraph instance
caching modules in IdeJavaModuleResolver, which is a project component.
Moreover, this will allow to report an error "named module does not read
unnamed module" in the compiler, and avoid reporting it in the IDE (see
the comment in IdeJavaModuleResolver about that)
No package annotations are going to be loaded, and
TypeQualifierDefault/TypeQualifierNickname are no longer recognized by
default. Use the CLI argument "-Xload-jsr305-annotations" to enable this
behavior back
#KT-10942
If a type is annotated as not null its upper bound is not nullable
in most cases besides override conflicts, but in the latter case
we should behave consistently with flexibility of this type
If a path to the module-info.java file is passed as an argument, we
should treat all other source files passed as arguments (either as
individual source files or inside a source directory) as members of that
module. Previously we treated other source files as members of the
unnamed module, and this resulted in incorrect errors when using a
member exported with a qualification from another named module, for
example
#KT-18598 In Fixed
To compute modules to be added to compilation roots in
JavaModuleGraph.getAllDependencies, we should look not only for
transitive requirements of root modules, but for transitive requirements
of _root modules' requirements_. The same logic applies to
JavaModuleGraph.reads. In other words, when looking for a path in the
module graph between two modules, the first edge's transitiveness
doesn't matter, but all other edges after the first must be transitive.
There was also a stupid bug in dfs in
JavaModuleGraph.getAllDependencies: we continued the DFS only if the
module _was not_ added to the "visited" set ("add" returns true if the
element was added successfully)
#KT-18598 In Progress
Previously we assumed that a symbol is accessible if its containing
package is exported by module-info.java. Which was obviously wrong and
could lead to a situation where a symbol would be incorrectly accessible
if a usage module has a dependency on the symbol's module in IDEA
project terms, but does not require it in its module-info.java
