This commit fixes an issue in StringDecoder, where, if the buffer did
not contain any delimiters, it was released before it was relayed to
any subscribers.

This commit introduces Micrometer as an API dependency to the
spring-webflux module. Micrometer is used here to instrument `WebClient`
and record `Observation` for HTTP client exchanges.
This replaces Spring Boot's `MetricsWebClientFilterFunction` which
instruments `WebClient` via an `ExchangeFilterFunction`. Here, a direct
instrumentation is more efficient and less prone to metrics errors.
See gh-28341
As of Java 18, the serial lint warning in javac has been expanded to
check for class fields that are not marked as `Serializable`.
See https://www.oracle.com/java/technologies/javase/18all-relnotes.html#JDK-8202056
In the Spring Framework codebase, this can happen with `Map`, `Set` or
`List` attributes which are often assigned with an unmodifiable
implementation variant. Such implementations are `Serializable` but
cannot be used as field types.
This commit ensures that the following changes are applied:
* fields are marked as transient if they can't be serialized
* classes are marked as `Serializable` if this was missing
* `@SuppressWarnings("serial")` is applied where relevant
Prior to this commit, several tests used ClassPathResource#getPath()
based on the knowledge that the ClassPathResource had been created
using the ClassPathResource(String,Class) constructor. However, making
such an assumption seems ill advised in light of the abstraction that
ClassPathResource provides.
In light of that, this commit avoids questionable use of
ClassPathResource#getPath() in tests by refactoring those tests to use
the proper abstractions provided by ClassPathResource.
This commit introduces support for Netty 5's Buffer, in the form of
Netty5DataBuffer. Because of the new API offered by Buffer, several
changes have been made to the DataBuffer API:
- CloseableDataBuffer is a simpler alternative to PooledDataBuffer, and
implemented by Netty5DataBuffer. DataBufferUtils::release can now
handle CloseableDataBuffer as well as PooledDataBuffer.
- PooledDataBuffer::touch has been moved into a separate interface:
TouchableDataBuffer, which is implemented by Netty5DataBuffer.
- The capacity of DataBuffers can no longer be reduced, they can only
grow larger. As a consequence, DataBuffer::capacity(int) has been
deprecated, but ensureWritable (formally ensureCapacity) still exists.
- DataBuffer::slice and retainedSlice have been deprecated in favor of
split, a new method that ensures that memory regions do not overlap.
- DataBuffer::asByteBuffer has been deprecated in favor of toByteBuffer,
a new method that returns a copy, instead of shared data.
- DataBufferFactory::allocateBuffer has been deprecated in favor of
allocateBuffer(int).

Not all HttpHeaders implementations are serializable. This commit
ensures that WebClientRequestException and WebClientResponseException
are serializable, by copying any non-serializable HttpHeaders into a
new, serializable, instance.

Prior to this commit, tests in these two classes intermittently failed
with errors similar to the following, due to concurrent modification
of shared files.
expected:
"<input type="text" id="name" name="name" value="Darren" >"
but was:
"<input type="text" id="name" name="name" value="Darren" >
"hidden"/>"
This commit fixes this by creating a new temporary folder for each test
method invocation.
Ideally one would pass WebClient directly to HttpServiceProxyFactory,
but two need to remain decoupled. This commit adds static, shortcut
methods to WebClientAdapter to create an HttpServiceProxyFactory, thus
eliminating the step to wrap the WebClient.
Prior to this commit, Spring MVC and Spring WebFlux would not support
conditional requests with `If-Match` preconditions. As underlined in the
RFC9110 Section 13.1, those are related to the `If-None-Match`
conditions, but this time only performing requests if the resource
matches the given ETag.
This feature, and in general the `"*"` request Etag, are generally
useful to prevent "lost updates" when performing a POST/PUT request: we
want to ensure that we're updating a version with a known version or
create a new resource only if it doesn't exist already.
This commit adds `If-Match` conditional requests support and ensures
that both `If-Match` and `If-None-Match` work well with `"*"` request
ETags.
We can't rely on `checkNotModified(null)`, as the compiler can't decide
between method variants accepting an ETag `String` or a Last Modified
`long`. Instead, developers should use empty ETags `""` to signal that
no resource is known on the server side.

A static nested class does not keep an implicit reference to its
enclosing instance.
This prevents a common cause of memory leaks and uses less memory per
instance of the class.
Closes gh-28433
Prior to this commit, the `name` attribute in @ModelAttribute was not
supported when using WebFlux. This is because MethodParameter was used
instead of SynthesizingMethodParameter when retrieving the
@ModelAttribute annotation. In other words, @AliasFor was not honored
because the annotation was not synthesized. Consequently, only the
`value` attribute was supported in WebFlux when specifying a custom name
via @ModelAttribute.
This commit fixes this by using SynthesizingMethodParameter to retrieve
the @ModelAttribute annotation.
Closes gh-28423
This commit introduces the PartEvent API. PartEvents are either
- FormPartEvents, representing a form field, or
- FilePartEvents, representing a file upload.
The PartEventHttpMessageReader is a HttpMessageReader that splits
multipart data into a stream of PartEvents. Form fields generate one
FormPartEvent; file uploads produce at least one FilePartEvent. The last
element that makes up a particular part will have isLast set to true.
The PartEventHttpMessageWriter is a HttpMessageWriter that writes a
Publisher<PartEvent> to a outgoing HTTP message. This writer is
particularly useful for relaying a multipart request on the server.
Closes gh-28006
This commit introduces explicit HEAD support in Spring
MVC's ResourceHttpRequestHandler and WebFlux's ResourceWebHandler,
adding just headers but no body.
Closes gh-28291
This commit ensures that any resources created for multipart handling,
obtained via ServerWebExchange.getMultipartData(), are automatically
deleted after handling the completing the response.
Resource for parts obtained via BodyExtractors::toMultipartData and
BodyExtractors::toParts are not cleaned automatically, and
should be cleaned via Part::delete.
Closes gh-27633
This commit contains changes made because of the introduction of
HttpStatusCode. In general, methods that used to return a HttpStatus
now return HttpStatusCode instead, and methods that returned raw status
codes are now deprecated.

Since the Nashorn JavaScript engine was removed in Java 15, these tests
will never be run on a Java 17+ JDK which is required as of Spring
Framework 6.0.

This commit makes sure that the response returned by coroutine handler
methods that return ResponseEntity<Flux> is unwrapped correctly.
Closes gh-27809
All Spring MVC exceptions from spring-web, now implement ErrorResponse
and expose HTTP error response information, including an RFC 7807 body.
See gh-27052
ErrorResponse represents a complete error response with status, headers,
and an RFC 7807 ProblemDetail body.
ErrorResponseException implements ErrorResponse and is usable on its
own or as a base class. ResponseStatusException extends
ErrorResponseException and now also supports RFC 7807 and so does its
sub-hierarchy.
ErrorResponse can be returned from `@ExceptionHandler` methods and is
mapped to ResponseEntity.
See gh-27052
ProblemDetail is a representation of an RFC 7807 "problem", and this
commits adds support for it in Spring MVC and WebFlux as a return value
from `@ExceptionHandler` methods, optionally wrapped with
ResponseEntity for headers.
See gh-27052
SocketUtils was introduced in Spring Framework 4.0, primarily to assist
in writing integration tests which start an external server on an
available random port. However, these utilities make no guarantee about
the subsequent availability of a given port and are therefore
unreliable. Instead of using SocketUtils to find an available local
port for a server, it is recommended that users rely on a server's
ability to start on a random port that it selects or is assigned by the
operating system. To interact with that server, the user should query
the server for the port it is currently using.
SocketUtils is now deprecated in 5.3.16 and will be removed in 6.0.
Closes gh-28052
In a small minority of cases, the multipart boundary can spread across
three incoming buffers.
Prior to this commit, MultipartParser.BodyState only supported two
buffers. If the boundary is spread across three buffers, the first
buffer of the three is sent as a whole, even though it contains the
first bytes of the boundary.
This commit fixes this bug, by enqueuing all prior buffers in a queue,
and emitting the ones that cannot contain boundary bytes.
Closes gh-27939
This commit introduces a dedicated (disabled) transferToWithUndertow()
test method to simplify debugging of transferTo issues with Undertow.
See gh-25310
Closes gh-27908
Instead of simply returning prematurely and allowing the tests to be
marked as SUCCESS, this commit uses a failed assumption to abort the
the trasferTo tests for Undertow, resulting in the parameterized test
invocation properly being marked as ABORTED.
See gh-25310
This commit makes it possible to customize 404 responses generated by
RouterFunctionWebHandler, by throwing an ResponseStatusException
instead of returning a standard 404 response.
