DefaultMultipartHttpServletRequest always returned mulitpart parameter
values only rather than aggregating with query parameters, which
contradicts with Servlet spec, section 3.1, and is inconsistent with
StandardMultipartHttpServletRequest.

This commit removes all places where forwarded headers are checked
implicitly, on an ad-hoc basis.
ForwardedHeaderFilter is expected to be used instead providing
centralized control over using or discarding such headers.

With this commit, WebFlux server uses warning instead of error log level
for request handling, and also just print the message instead of the
stacktrace which is mostly meaningless in reactive world.
Complementary to this change, Reactor Netty removed additional logging
as part of https://github.com/reactor/reactor-netty/issues/339.

ServerSentEventHttpMessageReader had logic to split on new lines
and buffer until an empty new line (start of a new event). To account
for random data chunking, it later re-assembled the lines for each
event and split again on new lines. However bufferUntil was still
unreliable a chunk may contain nothing but a newline, which doesn't
necessarily mean an empty newline in the overall SSE stream.
This commit simplifies the above by delegating the splitting of the
stream along newlines to StringDecoder.

Prior to this commit, the various `HttpMessageConverter` instances
configured for a given `RestTemplate` instance could all contribute
`MediaType` values to the "Accept:" request header.
This could lead to duplicate media types in that request header,
cluttering for the HTTP request for no reason.
This commit ensures that only distinct values are added to the request.

Using the simple example shown in the ticket but switching from
Mono<String> to Flux<String> (and 5,000,000 onNext calls) shows that
constant pausing causes significant overhead and is not worth the
trouble vs ignoring the onWritePossible in REQUESTED state.
Issue: SPR-16702
Undertow does not provide a way to check if we can write so with the
current implementation of isWritePossible, deep recursion can occur
when writing slows down. We now use a flag to keep track of write
ChannelListener callbacks.
This commit also addresses a related issue in
AbstractListenerWriteProcessor that went undected since #3c2d186
where after a large (single) buffer that is not written fully, the
completion signal is processed before the all data is written.

This commit documents the difference between configuring the socket
timeout on the `RequestConfig` and on the `SocketConfig`.
The first one does not affect timeouts when establishing an SSL
connection or sending a CONNECT request to a proxy. For these use cases,
it is required to configure `SocketConfig` on the `HttpClient` instance
directly.
Issue: SPR-16697
This breaks the package dependency cycle between web.server/web.method and makes ServerErrorException more generally applicable. Includes deprecation of the plain reason constructor variant, in favor of providing a Method or MethodParameter context (which MatrixVariableMethodArgumentResolver does now).
Consistently return "*/*" if no media types were requested rather than
an empty list. Existing code has to check for both in any case to see
if nothing was requested.
Issue: SPR-16624
The web.server package is quite low-level and should not depend on web.bind in order to avoid a dependency cycle. Extracting the introspection of the ResponseStatus annotation into a WebFlux-level subclass resolves the cycle.
Issue: SPR-16567
Undertow does not provide a way to check if data is available to read
but instead we have to try to read and see if any data is returned.
This makes it impossible to implement checkOnDataAvailable without
trying to read and that can lead to infinite recursion like this:
...
UndertowServerHttpRequest$RequestBodyPublisher.checkOnDataAvailable(UndertowServerHttpRequest.java:156)
AbstractListenerReadPublisher.changeToDemandState(AbstractListenerReadPublisher.java:177)
AbstractListenerReadPublisher.access$900(AbstractListenerReadPublisher.java:47)
AbstractListenerReadPublisher$State$4.onDataAvailable(AbstractListenerReadPublisher.java:319)
AbstractListenerReadPublisher.onDataAvailable(AbstractListenerReadPublisher.java:85)
UndertowServerHttpRequest$RequestBodyPublisher.checkOnDataAvailable(UndertowServerHttpRequest.java:156)
This commit prevent the call to checkOnDataAvailable() when switching
states from READING->DEMAND which implies we exited the readAndPublish
loop because there was no more data to read.
Issue: SPR-16545
When checking whether there is still request body the first method
that should be checked is ServletInputStream.isReady() and then
ServletInputStream.isFinished(). ServletInputStream.isReady() is the active
method whereas the ServletInputStream.isFinished() is not.
It is important to call ServletInputStream.isReady() because if it returns
false it will schedule a dispatch and if the request body is already read it will
send onAllDataRead event.
Issue: SPR-16521
Jackson2Tokenizer now also wraps JsonProcessingException's on
endOfInput(), as it also does in tokenize(DataBuffer). This ensures
treating those errors as 400 vs 500.
Issue: SPR-16521
When read returns -1, we know we've reached the end of input. Instead
of waiting for the onAllDataRead container callback, this commit
proactively calls onAllDataRead.

Make the protected fields in AbstractJackson2Encoder private plus
minor refactoring to the way streaming separators are applied.
The current (5.0.3) behavior is to always use '\n', but in 5.0.4 the
newly supported "application/stream+x-jackson-smile" needs to be
excluded from that. For now, separator determination remains private
in the abstract base class, but current behavior remains which is to
apply '\n' by default.
Issue: SPR-15424
This commit introduces DataBuffer.asInputStream(boolean), that can
release the underlying buffer when the stream is closed.
Furthermore, this commit adds additional javadoc.
Issue: SPR-16444
After this commit the use of interval in tests is combined with
take(n).onBackpressureBuffer(n) to ensure emissions don't fail if the
fixed rate is exceeded (e.g. on slow CI server).
Tests that verify N number of items followed by verifyOnComplete()
should set the number of emissions to N.
Tests that verify N number of items followed by thenCancel() should
set the number of buffered to an arbitrary number greater than N.
This commit updates HttpWebHandlerAdapter and
ResponseStatusExceptionHandler in order to specify the method/uri in the
logged message.
It also logs a WARN message for bad request (400) HTTP responses in
order to get some logs when an exception is thrown due to client error
(unable to deserialize request body for example).
