This new option allows a cancel signal to abort the request, which is
how we expect a connection to be aborted in a reactive chain that
involves the WebClient.

Prior to this commit, the `NettyHeadersAdapter` would directly delegate
the `add()` and `set()` calls to the adapted
`io.netty.handler.codec.http.HttpHeaders`. This implementation rejects
`null` values with exceptions.
This commit aligns the behavior here with other implementations, by not
rejecting null values but simply ignoring them.
Fixes gh-26274
HttpMessageWriter implementations now attach the request log prefix
as a hint to created data buffers when the logger associated with
the writer is at DEBUG level.
Closes gh-26230
This commit improves the Javadoc for the `ForwardedHeaderFilter`
(Servlet Filter) and `ForwardedHeaderTransformer` (reactive variant) so
as to mention security considerations linked to Forwarded HTTP headers.
Closes gh-26081
This commit adds support for sending Server-Sent Events in WebMvc.fn,
through the ServerResponse.sse method that takes a SseBuilder DSL.
It also includes reference documentation.
Closes gh-25920
This commit introduces the following changes:
- Converters/codecs are now used based on generic type info.
- On WebMvc and WebFlux, kotlinx.serialization is enabled along
to Jackson because it only serializes Kotlin @Serializable classes
which is not enough for error or actuator endpoints in Boot as
described on spring-projects/spring-boot#24238.
TODO: leverage Kotlin/kotlinx.serialization#1164 when fixed.
Closes gh-26147
This commit only writes the 'charset' parameter in the written headers
if it is non-default (not UTF-8), since RFC7578 states that the only
allowed parameter is 'boundary'.
Closes gh-25885
There are more locations which could benefit from not using a
toCharArray on a String, but rather use the charAt method from
the String itself. This to prevent an additional copy of the
char[] being created.
Prior to this commit, references to `JsonGenerator` and
`ByteArrayBuilder` were not closed/released within codecs calls.
This prevents Jackson from reusing more efficiently shared memory
resources.
This commit properly closes/releases Jackson resources in Spring MVC,
Spring WebFlux and Spring Messaging codecs.
A benchmark on WebFlux codecs (in both single value/streaming mode)
shows significant throughput and allocation improvements for small
payloads.
Closes gh-25910
This commit adds support for Kotlin Coroutines suspending functions to
Spring MVC, by converting those to a Mono that can then be handled by
the asynchronous request processing feature.
It also optimizes Coroutines detection with the introduction of an
optimized KotlinDetector.isSuspendingFunction() method that does not
require kotlin-reflect.
Closes gh-23611
Flow decoding is not supported yet since it depends on
kotlin/kotlinx.serialization#1073, but it will be
enabled when this issue will be fixed.
Closes gh-25771
The workaround was removed in the 5.3 milestone phase and in master
only because the referenced Jetty issue is marked fixed. However,
what we need to replace it with should be a little more involved
and also it's not entirely clear if the fixes in Jetty aligns with
our release and retain semantics so that needs to be investigated
more thoroughly.
Prior to this commit, the Series value for an HttpStatus was always
evaluated which resulted in an allocation of a Series array by invoking
Series.values() which makes a defensive copy.
This commit addresses this issue by hardcoding the corresponding Series
within the HttpStatus constructor, thereby avoiding any unnecessary
computations. In addition, a unit test has been added to verify that
all HttpStatus enum constants have a properly configured Series.
Closes gh-22366
This commit deprecates LiveBeansView and related classes in order to allow
a future removal in order to increase the separation of concerns between
Spring Framework and Spring Boot, and the consistency between JVM
and native.
Closes gh-25820
