Where `isOptional` is used, also check for `isNullable` i.e.
values are not considered required if they are Kotlin nullables:
- spring-messaging: named value method arguments
- spring-web: named value method arguments
- spring-webmvc: request parts
This means that Kotlin client code no longer has to explicity specify
"required=false" for Kotlin nullables -- this information is inferred
automatically by the framework.
Issue: SPR-14165
- ScriptedSubscriber has been renamed to Verifier
- The Publisher is passed to create() instead of verify()
- No more need to specify the generic type explicitly
- Version is now sync with reactor-core
Issue: SPR-14800
Reactor recently added the `ScriptedSubscriber` in its new
`reactor-addons` module. This `Subscriber` revissits the previous
`TestSubscriber` with many improvements, including:
* scripting each expectation
* builder API that guides you until the final verification step
* virtual time support
This commit refactor all existing tests to use this new
infrastructure and removed the `TestSubscriber` implementation.
Issue: SPR-14800
This commit removes the usage of Reactor adapters (about to
be moved from Reactor Core to a new Reactor Adapter module).
Instead, RxReactiveStreams is now used for adapting RxJava
1 and Flowable methods are used for RxJava 2.
Issue: SPR-14824
This commit adds the necessary infrastructure for the support of HTTP
Range requests. The new `ResourceRegionEncoder` can write
`ResourceRegion` objects as streams of bytes.
The `ResourceRegionEncoder` relies on an encoding hint
`BOUNDARY_STRING_HINT`. If present, the encoder infers that multiple
`ResourceRegion`s should be encoded and that the provided boundary
String should be used to separate ranges by mime boundaries.
If that hint is absent, only a single resource region is encoded.
Issue: SPR-14664
Added readableChannel() to Resource, which returns a
java.nio.ReadableByteChannel. The default implementation uses
Channels.newChannel() to create a channel based on what is returned from
getInputStream(). Subclasses have more effecient, file-based
implementations.
Issue: SPR-14698
Fixed bug where the returned Flux from DataBufferUtils.read() would be
completed prematurely if the channel was not ready to read, but did
not reach the end of the file either.
