Bump org.jetbrains.kotlinx:kotlinx-serialization-json from 1.6.2 to 1.7.1

[dependabot]

Bumps org.jetbrains.kotlinx:kotlinx-serialization-json from 1.6.2 to 1.7.1.

Release notes

Sourced from org.jetbrains.kotlinx:kotlinx-serialization-json's releases.

1.7.1

This is a bugfix release that aims to fix missing kotlinx-serialization-hocon artifact. It also contains experimental integration with kotlinx-io library. Kotlin 2.0.0 is used by default.

Fixed HOCON publication

Sadly, 1.7.0 release was published incomplete: kotlinx-serialization-hocon artifact is missing from 1.7.0 and 1.7.0-RC releases. This release fixes this problem and now kotlinx-serialization-hocon is available again with 1.7.1 version. No other changes were made to this artifact. Related ticket: #2717.

Add integration with a kotlinx-io library

kotlinx-io is an official multiplatform library that provides basic IO primitives, similar to Okio. kotlinx.serialization integration is now available in a separate artifact, located at the kotlinx-serialization-json-io coordinates. Integration artifact provides functions similar to existing Okio integration: encodeToSink, decodeFromSource, and decodeSourceToSequence. Check out the PR for more details.

Other bugfixes

• Prohibited use of elements other than JsonObject in JsonTransformingSerializer with polymorphic serialization (#2715)

1.7.0

This release contains all of the changes from 1.7.0-RC and is compatible with Kotlin 2.0. Please note that for reasons explained in the 1.7.0-RC changelog, it may not be possible to use it with the Kotlin 1.9.x compiler plugin. Yet, it is still fully backward compatible with previous versions.

The only difference with 1.7.0-RC is that the classDiscriminatorMode property in JsonBuilder is marked as experimental, as it should have been when it was introduced (#2680).

1.7.0-RC

This is a release candidate for the next version. It is based on Kotlin 2.0.0-RC3 and is fully compatible with a stable Kotlin 2.0 release. Due to a potential breaking change (see below), it requires a compiler plugin with a version at least of 2.0.0-RC1.

Important change: priority of PolymorphicSerializer for interfaces during call to serializer() function

Non-sealed interfaces in kotlinx.serialization are always serializable with a polymorphic serializer, even if they do not have @Serializable annotation. This also means that serializersModule.serializer<SomeInterface>() call will return you a serializer capable of polymorphism. This function was written in a way that it unconditionally returns a PolymorphicSerializer if type argument is a non-sealed interface. This caused problems with SerializersModule functionality, because actual module was not taken into consideration, and therefore it was impossible to override serializer for interface using 'contextual serialization' feature. The problem is described in detail here. To overcome these problems, we had to change the behavior of this function regarding interfaces. It now looks into SerializersModule first if T is a non-sealed interface, and only if there is no registered contextual serializer for T, it returns a polymorphic serializer.

Behavior before 1.7.0-RC:

interface SomeInterface
val module = SerializersModule {
contextual(SomeInterface::class, CustomSomeInterfaceSerializer)
}
// Prints PolymorphicSerializer<SomeInterface>:
println(module.serializer<SomeInterface>())

Behavior in 1.7.0-RC, 1.7.0, and higher:
