Prior to this commit, the `WebHttpHandlerBuilder` would only configure
a custom observation convention if there is a single convention in the
application context. It would other wise use the default.
This commit aligns with the previous Spring Boot behavior where multiple
conventions setups are rejected as invalid with
`NoUniqueBeanDefinitionException`.
Fixes gh-31864
This commit refines InvocableHandlerMethod (both Servlet and
Reactive variants) in order to support annotated property
accessors as they translate into regular Java methods, instead
of throwing a NullPointerException.
Closes gh-31856
DataBinder should skip any jakarta.validation.Validator yielding
to method validation when that is expected. This change improves
the check to skip by unwrapping the validator from in a
SmartValidator before checking if it is for bean validation.
Closes gh-31711
Method validation needs to be used for a container such as a List or
Map, but until now we were only checking for a List container.
Moreover, in gh-31530 we improved method validation to also cover
any Collection.
This change aligns with HandlerMethod check for when method validation
applies with the underlying ability of method validation.
This commit builds on top of changes made in gh-29775 and gh-31737.
Before this change, we would allocate several byte arrays even in cases
of known request size. This could decrease performance when getting the
cached content as it requires merging several arrays and data is not
colocated in memory.
This change ensures that we create a `FastByteArrayOutputStream`
instance with the known request size so that the first allocated segment
can contain the entire content.
If the request size is not know, we will default back on the default
allocation size for the `FastByteArrayOutputStream`.
Closes gh-31834
This commit documents the fact that any (Unchecked)IOExceptions or
HttpMessageNotReadableExceptions thrown from the error handler will be
wrapped in a RestClientException.

This commit fixes a bug in DefaultPartHttpMessageReader's
MultipartParser, due to which the last token in a part window was not
properly indicated.

This commit introduces a toString() overload in
FastByteArrayOutputStream that accepts a Charset in order to mirror the
method that was introduced in ByteArrayOutputStream in JDK 10,
including a special case for when a single buffer is in use internally
to avoid the need to resize.
This commit also updates getContentAsString() in
ContentCachingRequestWrapper to use this new toString(Charset) method.
Closes gh-31737
This commit ensures that the RestClient uses the
IntrospectingClientHttpResponse to verify whether the response has a
body, and return null if it does not.
See gh-12671
Closes gh-31719
The getContentAsString method was originally added in d9b8826 to avoid
the extra copying inherent to calling ByteArrayOutputStream.toByteArray;
however, in f83c609 the class was updated to instead use
FastByteArrayOutputStream, and in the process the extra copy was brought
back when getContentAsString was changed to call toByteArray.
Switch to calling toByteArrayUnsafe, a method provided by
FastByteArrayOutputStream, which avoids the extra copy; since we
immediately pass the byte array to the String constructor, and it isn't
accessed anywhere else, the usage is safe.
See gh-31731
Prior to this commit, regressions were introduced with gh-31417:
1. the observation keyvalues would be inconsistent with the HTTP response
2. the observation scope would not cover all controller handlers, causing
traceIds to be missing
The first issue is caused by the fact that in case of error signals, the
observation was stopped before the response was fully committed, which
means further processing could happen and update the response status.
This commit delays the stop event until the response is committed in
case of errors.
The second problem is caused by the change from a `contextWrite`
operator to using the `tap` operator with a `SignalListener`. The
observation was started in the `doOnSubscription` callback, which is too
late in some cases. If the WebFlux controller handler is synchronous
non-blocking, the execution of the handler is performed before the
subscription happens. This means that for those handlers, the
observation was not started, even if the current observation was
present in the reactor context. This commit changes the
`doOnSubscription` to `doFirst` to ensure that the observation is
started at the right time.
Fixes gh-31703
Fixes gh-31706
Prior to this commit, the Jackson 2.x encoders, in case of encoding a
stream of data, would first release the `ByteArrayBuilder` and then the
`JsonGenerator`. This order is inconsistent with the single value
variant (see `o.s.h.codec.json.AbstractJackson2Encoder#encodeValue`) and
invalid since the `JsonGenerator` uses internally the
`ByteArrayBuilder`.
In case of a CSV Encoder, the codec can buffer data to write the column
names of the CSV file. Writing an empty Flux with this Encoder would not
fail but still log a NullPointerException ignored by the reactive
pipeline.
This commit fixes the order and avoid such issues at runtime.
Fixes gh-30493
This commit fixes a regression introduced by gh-21139
via the usage of Kotlin reflection to invoke HTTP
handler methods. It ensures that kotlin.Unit is treated
as void by returning null.
It also polishes CoroutinesUtils to have a consistent
handling compared to the regular case, and adds related
tests to prevent future regressions.
