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.

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).
Issue: SPR-16447
MockHttpServletResponse no longer calls flushBuffer on calls to
getContentAsByteArray and getContentAsString. The flushing doesn't
actually do anything useful but does commit the response leading to
unexpected side effects.
Issue: SPR-16430
This commit adds these 2 Vary headers in addition to the existing
Origin one to avoid caching of Access-Control-Request-Method and
Access-Control-Request-Headers headers which can be an issue
when allowed methods or headers are unbounded and only the
requested method or headers are returned in the response.
Issue: SPR-16413
The commit brings following changes:
- Move getDecodableMimeTypes() to AbstractJackson2Decoder
- Move getEncodableMimeTypes() to AbstractJackson2Encoder
- Add support for application/stream+x-jackson-smile
- Avoid streaming line separator when Smile encoder is used
- Use double null token in Jackson2Tokenizer to identify documents
Issue: SPR-16151
The resolved URI instance is also being cached now. This should not make a difference in a real Servlet environment but does affect tests which assumed they could modify an HttpServletRequest path behind a pre-created ServletServerHttpRequest instance. Our WebSocket test base class has been revised accordingly, re-creating the ServletServerHttpRequest in such a case.
Issue: SPR-16414
This commit makes sure there is no custom Content-Disposition header
before setting one automatically.
This commit also adds a headers(Consumer<HttpHeaders>) method, so that
one can user the nicer methods of HttpHeaders, as opposed to basic
strings.
Issue: SPR-16376
Since Java7 HttpURLConnection offers setFixedLengthStreamingMode method with long parameter which should be prefered over version with int argument, therefore casting ContentLength to int is no longer needed. Moreover it makes impossible to stream payload larger than Integer.MAX_VALUE
Now that SPR-16307 makes it possible to write a part with a Publisher
we need to ensure we get the filename correctly when writing with
Publisher<Resource>.
Issue: SPR-16376
The previous fix #09f1f7 did not actually address the issue but only
moved it further down, so instead of the subscribe(), it was consuming
it inside the MultipartHttpMessageWriter#write method which returned
this.body.then(), and then again for the actual request body writing.
In this commit MultipartHttpMessageWriter#write returns Mono.empty()
since we don't actually want to write the part content from there, but
only want to access it as soon as it is availabele, for writing to
the request body.
Issue: SPR-16402
Use DataBufferUtils.compose instead of writeAggregator to combine
multiple data buffers into one, as the write aggregator would not work
when the initial data buffer did not have enough capacity to contain
all subsequent buffers.
Removed writeAggregator, as it is no longer needed.
Issue: SPR-16365
The match/matches methods of UriTemplate use a regex with (.*) in place
of URI variables, which work fine except in the end where such a
pattern can match greedily more than one segment.
This commit updates the regex to use ([^/]*) instead since URI
variables are only meant to be used within a single path segment.
Issue: SPR-16169
Optimize same origin check when the request is an instance of
ServletServerHttpRequest and when there is no forwarded headers.
This commit also optimizes the getPort methods and ForwardedHeaderFilter
forwarded headers checks.
Issue: SPR-16262
This commit refines forwarded protocol support in order to support
proxies that only set "X-Forwarded-Proto" header and not
"X-Forwarded-Port" by performing a reset of the port in such case.
"Forwarded" header support has been updated accordingly since it
also supports similar use case, as described in SPR-15504.
Issue: SPR-16262
Since type erasure can be fixed only when using
ParameterizedTypeReference based Java methods, RestOperations and
WebFlux API documentation should be updated to specify which extensions
are subject to type erasure, and which are not.
Issue: SPR-16273
This commit moves the ResolvableType field from HttpEntity to
PublisherEntity, a new entity type defined in MultipartBodyBuilder.
With this change, the scope of the ResolvableType is limited to
multipart-related code, instead of becoming part of the complete
HttpEntity hierarchy.
Issue: SPR-16307
This commit adds a ResolvableType field to HttpEntity, in order to
support Publishers as multipart data. Without the type, the
MultipartHttpMessageWriter does not know which delegate writer to use to
write the part.
Issue: SPR-16307
This commit allows CorsConfiguration#combine()
to differentiate permit default values set by
CorsConfiguration#applyPermitDefaultValues()
from values configured explicitly by the user.
Those permit default values will be overridden
by any user-provided ones while user-provided values
will be combined in an additive way, including
when "*" is specified.
Documentation has been improved accordingly.
Issue: SPR-15772
If the response is set and we can't change the status through
ServerHttpResponse any more, allow the error signal to propagate and
let the individual server adapters handle it. Ultimately that should
result in closing the connection.
On Servlet containers, we check one last time if the response is
committed (we may not have filled the buffer). If not then save
the exception as a request attribute, dispatch, and re-throw it on the
container thread.
On Undertow access the connection and close it.
On Netty just let the error through to Reactor Netty.
Issue: SPR-16051
Provide a fully mutable HttpHeaders to ClientHttpRequestInterceptors
of a RestTemplate when headers are set using HttpEntity. This avoids
UnsupportedOperationException if both HttpEntity and
ClientHttpRequestInterceptor add values for the same HTTP header.
Issue: SPR-15066
The request URI returned from HttpServerRequest.uri() typically
contains contains an absolute path but could also contain an
absolute URI. This commit adds handling for the latter, effectively
taking only the absolute path portion.
Issue: SPR-16243
ResponseStatusExceptionHandler lets the error through if it can't
change the status while HttpWebHandlerAdapter logs a more helpful
message (including status code) but without a full stack trace.
Issue: SPR-16231
1. setComplete checks the isCommitted flag to avoid an unnecessary
debug message. This method is meant to be safe to call many times.
2. setStatusCode lowers log message to TRACE, since the return value
communicates the outcome it's arguably much less critical.
3. Add comment and test case for ResponseStatusExceptionHandler.
A ResponseStatusException is clearly meant to be handled by this
handler so don't let it pass through even if the respones is
committed.
Issue: SPR-16231
Before this commit, the return value from write was interpreted as the
data being fully written and ready to be released via releaseData().
This is not true for WebSocketSession implementations where a true
return value simply means the message was sent with the full payload
but releas is not appropriate until a send confirmation.
Technically not an issue since WebSocketSession's extending this do
not use pooled buffers. Nevertheless this commit refines the semantics
of write, removes the releaseData() method, and makes sub-classes
responsible for releasing the buffer when fully written (and they
know best when that is). As a bonus currentData is now private.
Issue: SPR-16207
This commit turns suspendReading() into a readingPaused() notification
that is invoked after a succession of reads stops because there is no
more demand. Sub-classes can use this notification to suspend, if that
applies to them.
Most importantly the notification is guaranteed not to overlap with
checkOnDataAvailable() which means that suspend does not need to be
atomic and guarded against resume. The two can and do compete all the
time when reading ends with no demand, and a request for demand arrives
concurrently.
Issue: SPR-16207
Access-Control-Allow-Credentials CORS header, used to
allow cookies with CORS requests, is not set to true
anymore by default when enabling CORS with
@CrossOrigin or global CORS configuration in order to
provide a more secured default CORS configuration.
The related allowCredentials property now requires to
be set to true explicitly in order to support cookies
with CORS requests.
Issue: SPR-16130
Transition from DEMAND->NO_DEMAND:
Two concurrent threads enter DEMAND.request and DEMAND.onDataAvailable.
And DEMAND.onDataAvailable finishes before DEMAND.request to be able to
update the demand field then a request for reading will be lost.
Transition from READING->NO_DEMAND:
readAndPublish() returns false because there is no demand but before
switching the states READING.request is invoked again a request for
reading will be lost.
Changing READING->DEMAND/NO_DEMAND is made conditional so that the
operations will be executed only if changing states succeeds.
When in READING state detect completion before each next item in order
to exit sooner, if completed.
Issue: SPR-16207
- Ensure completion signal (normal/exception) will be delivered to
the subscriber when transition from UNSUBSCRIBED->COMPLETED
- According to the specification "Publisher.subscribe MUST call onSubscribe
on the provided Subscriber prior to any other signals to that Subscriber" so
ensure onComplete/onError signals will be called AFTER onSubscribe signal.
Issue: SPR-16207
This commit changes the implementation of the PathPattern
extractPathWithinPattern method that used an old AntPathMatcher
derivative to a new version that integrates more closely with
PathContainer.
It also introduces consistency in a couple of areas. The javadoc
is updated to specify this but basically:
- the response from the extra method will have all leading
and trailing separators removed.
- the response will have multiple adjacent separators within the
reponse reduced to just one. (For example response would be
aaa/bb/cc and not aaa///bbb//cc)
If your response would start or finish with multiple separators, they
are all removed.
Issue: SPR-16120
- When there is no demand for reading, the implementation
should suspend reading otherwise useless events will be
send by Undertow to the registered read listener.
- There is not need to wait for an event for reading/writing after calling
resumeReads/resumeWrites
Practically no changes to RxNetty for a year and efforts underway to
rebuild 0.6.x based on a current Reactor Netty base.
Aside from the extra time to run integration tests having two
Netty-based servers can also cause false alarms such as ByteBuf leaks
related to RxNetty.
Also remove ErrorDeferredResultProcessingInterceptor which was meant
to be package private to begin with as its peer
ErrorCallableProcessingInterceptor (also removed).
Includes fixes for invalid exception declarations in Mockito-based unit tests. Also includes FreeMarker 2.3.27, Commons Pool 2.4.3, JSON-P 1.1.2.
Issue: SPR-16157
This commit introduces a new AbstractReactiveWebInitializer in
spring-web that relies on WebHttpHandlerBuilder to detect request
processing infrastructure beans from an ApplicationContext.
This eliminates the need to create a DispatcherHandler, since it is
expected to be a Spring bean, and as a result the initializers in
spring-webflux have been deprecated.
Issue: SPR-16144
The RFCs around basic authentication don't explicitly disallow empty
usernames. On the other hand usernames containing colons are, as colons
are used to separate the username from the password.
FromHttpMessageWriter and MultipartHttpMessageWriter both support
MultiValueMap except the former supports String values only. This
presents an issue since either full generic type information must be
provided, which is cumbersome on the client side, or if left out there
is no good way to order the writers to make a proper decision.
This commit:
- refines the canWrite behavior of to not a
accept MultiValueMap without proper generic information unless the
MediaType is explicitly set providing a strong hint.
- modifies MultipartHttpMessageWriter to be configured with a
FormHttpMessageWriter so it can write both plan and multipart data with
the ability to properly differentiate based on actual map values.
Issue: SPR-16131
This commit changes the way Undertow's PooledByteBuffers are dealt with.
Previously, these buffers where closed as soon as all data was read. As
of this commit, the UndertowServerHttpRequest returns PooledDataBuffers
from getBody(), so that the buffers are released when release() is
called.
This commit introduces various improvements in DataBuffer:
- DataBuffer now exposes its read and write position, as well as its
capacity and writable byte count.
- Added DataBuffer.asByteBuffer(int, int)
- DataBufferUtils.read now reads directly into a DataBuffer, rather than
copying a ByteBuffer into a DataBuffer
- TomcatHttpHandler now reads directly into a DataBuffer
