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.

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.
See gh-28214
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.
