Prior to this commit, Spring WebFlux function would let
`DecodingException` thrown by codecs bubble up to the web handler level.
Since this exception is not handled by default there, the response would
be turned into a HTTP 500 status.
In the annotation model, `ArgumentResolver` implementations wrap this
exception with a `ServerWebInputException`, which itself extends
`ResponseStatusException`. The latter is supported by the error handling
infrastructure as a HTTP 400 response.
This commit ensures that `DecodingException` instances are properly
wrapped in `ServerWebInputException` at the `ServerRequest` level
directly, thus supporting all setup modes ("standalone" and through the
`DispatcherHandler`).
Fixes#22290
Prior to this commit, `DataBuffer.write` would throw an
`IllegalStateException` when called with an empty `String`, since the
`CharsetEncoder` would be flushed on an incorrent state.
This commit skips entirely the encoding phase for empty `String`.
Fixes#22262
This allows for proper nested type conversion in @Value Optional fields analogous to method parameters, through a new TypeDescriptor-based method in the TypeConverter SPI. As an additional and less involved measure that is worth backporting, DefaultListableBeanFactory defensively checks for pre-converted Optional wrappers.
Issue: SPR-17607
Commit #93b7a4 added support for pre-configuring URI variables at the
UriComponentsBuilder level, and also changed toUriString to encode
template and URI variables separately. However this went a bit too far
causing side effects for URLs with curly braces that don't represent
URI variables.
This commit restores the original toUriString behavior which is to
encode template and URI variables sepraately only if URI variables have
been pre-configured.
Issue: SPR-17630
The xml parser does not fill in defaults provided in the XSD when
validation is disabled. As a result, attributes like default-lazy-init
will not receive the value "default" but an empty string.
With this commit, BeanDefinitionParserDelegate now takes this into
account, checking default values against empty string as well as
"default".
As a consequence, default-lazy-init attribute should now work correctly
even when the XSD validation is disabled.
Issue: SPR-8335
Reactor is now building its Javadoc with a recent JDK version, which
changes the structure of the published HTML pages.
Without this change, the build fails during the Dokka generation with
the following exception:
```
Exception while loading package-list from
ExternalDocumentationLinkImpl(
url=http://projectreactor.io/docs/core/release/api/,
packageListUrl=http://projectreactor.io/docs/core/release/api/package-list)
```
This commit now points to the `/element-list` page, which seems to
contain the same information as the `package-list` page.
Aalto's InputFactoryImpl already disables loading of external entities
by default (property "javax.xml.stream.isSupportingExternalEntities").
This commit goes further by applying the same defensive measures as we
do elsewhere for XMLInputFactory, which disables DTD completely.
Arguably there is no good reason to enable that by default in WebFlux.
Typically a straight up equals as well as Collections#contains
checks for MediaType.ALL is susceptible to the presence of
media type parameters.
This commits adds equalsTypeAndSubtype as well as an
isPresentIn(Collection<MimeType>) methods to MimeType to faciliate
with checks for MediaType.ALL.
Issue: SPR-17550
Prior to this commit, one could write a `CharSequence` to an existing
`DataBuffer` instance by turning it into a byte array or `ByteBuffer`
first. This had the following disadvantages:
1. Memory allocation was not efficient (not leveraging pooled memory
when available)
2. Dealing with `CharsetEncoder` is not always easy
3. `DataBuffer` implementations, like `NettyDataBuffer` can use
optimized implementations in some cases
This commit adds a new `DataBuffer#write(CharSequence, Charset)` method
for those cases and also an `ensureCapacity` method useful for checking
that the current buffer has enough capacity to write to it..

This commit makes TomcatServerHttpRequest aware of

Issue: SPR-17611
Commit #c187cb2 introduced proactive rejection of multiple subscribers
in ReactorClientHttpResponse, instead of hanging indefinitely as per
https://github.com/reactor/reactor-netty/issues/503.
However FluxReceive also rejects subsequent subscribers if the response
is consumed fully, as opposed to being canceled, e.g. as with
bodyToMono(Void.class). In that case, a subsequent subscriber causes
two competing error signals to be sent, and one gets dropped and
logged by reactor-core.
This fix ensures that a rejection is raised in
ReactorClientHttpResponse only after a cancel() was detected.

Response status 415 (unsupported media type) reported as of 416 (which is Range Not Satisfiable), mismatching with superclass constructor parameter HttpStatus.UNSUPPORTED_MEDIA_TYPE
Prior to this change, ResourceUrlEncodingFilter would try to resolve
the resource path using request URL without removing fragment first,
whereas only paths should be used.
This commit synchronizes behavior of ResourceUrlEncodingFilter with
behavior of ResourceUrlProvider.
Issue: SPR-17535
Prior to this commit, parallel invocations of
MethodParameter.findParameterIndex() (invoked indirectly via
SynthesizingMethodParameter.forParameter() and
MethodParameter.forParameter()) could intermittently lead to an
IllegalArgumentException being thrown due to a race condition in the
internal implementation of the JDK's
java.lang.reflect.Executable.getParameters() method.
This commit addresses this issue by introducing a fallback for-loop
that iterates over the candidate parameters a second time using
equality checks instead of identity checks.
Issue: SPR-17534
Prior to this commit, parallel execution of @BeforeEach and @AfterEach
methods that accepted @Autowired arguments would fail intermittently
due to a race condition in the internal implementation of the JDK's
java.lang.reflect.Executable.getParameters() method.
This commit addresses this issue by creating instances of
SynthesizingMethodParameter via
SynthesizingMethodParameter.forExecutable(Executable, int) instead of
SynthesizingMethodParameter.forParameter(Parameter), since the latter
looks up the parameter index by iterating over the array returned by
Executable.getParameters() (which is not thread-safe).
Issue: SPR-17533
This commit introduces a new readMessageSize(DataBuffer input) private
method, inspired from CodedInputStream#readRawVarint32(int, InputStream)
and adapted for DataBuffer using MessageDecoderFunction fields in
order to support use cases where the message size is split between
distinct chunks.
It also fixes handling of end of streams by using
DataBuffer#readableByteCount instead of -1 which is only relevant with
InputStream.
Issue: SPR-17429
Prior to this commit, when errors happened before the response was
committed, the `Content-Length` response header would be left as is.
This can be problematic since the error can be handled later in the
chain and the response body changed accordingly. For example, Spring
Boot renders error pages in those cases. If the `Content-Length` is set,
HTTP clients can get confused and only consider part of the error
response body.
This commit ensures that any `Content-Length` response header is removed
in case of errors, if the response is not already committed.
This is done at the `AbstractServerHttpResponse` level, since errors can
be handled in multiple places and the response itself is the safest
place to handle this case.
As a consequence, this commit also removes `Content-Length` checks in
`EncoderHttpMessageWriter` since we now consider that we should rely on
the response body we're about to write rather than any previously set
value.
Issue: SPR-17502
Update the ServerHttpRespnose contract to indicate that server specific

Issue: SPR-17368
This commit reverts the first optimizations listed in
fa096dc60f, as the default delimiters
do vary, namely by the charset given in the message mime type.
The mimetype charset might not be compatible with ASCII (i.e. anything
but UTF-8 or ISO-8859-1, for instance it might be UTF-16), and will not
successfully find the default delimiters as a consequence.
Added test to indicate the bug.
This CGLIB upgrade literally does not make any difference to Spring users since its only purpose is a default ASM7 declaration in its AsmApi class (which we patched a month ago). We nevertheless leave our local AsmApi copy in place for the time being, allowing for an individual upgrade of the declared ASM API version in the future.

After the fix #658c7f for lenient parsing of dates, the error message
raised uses an HttpHeaders-formatted date. As a result the test
verifying the error message fails in the beginning of the month between
1-9 because it's formatted slightly differently.
This commit makes the 3 existing InvocableHandlerMethod types more
consistent and comparable with each other.
1. Use of consistent method names and method order.
2. Consistent error formatting.
3. Explicit for loops for resolving argument values in webflux variant
because that makes it more readable, creates less garabage, and it's
the only way to bring consistency since the other two variants cannot
throw exceptions inside Optional lambdas (vs webflux variant which can
wrap it in a Mono).
4. Use package private HandlerMethodArgumentComposite in webflux
variant in order to pick up the resolver argument caching that the
other two variants have.
5. Polish tests.
6. Add missing tests for messaging variant.
1. Avoid re-creating the List with delimited byte arrays on every
request if using the default delimiters which don't vary by charset.
2. Replace flatMap with flatMapIterable for splitOnDelimiter.
3. Avoid going through DataBufferUtils#join, and unnecessarily creating
Flux from the List, since the join method needs a list anyway.
Prior to this commit, no `ResourceUrlProvider` was configured
in WebFlux (no bean was contributed by the WebFlux infrastructure).
Also, several `ResourceTransformer` instances that extend the
`ResourceTransformerSupport` base class need a `ResourceUrlProvider`
to resolve absolute URLs when rewriting resource URLs. At this point,
no `ResourceUrlProvider` was configured and they could only resolve
relative URLs.
This commit contributes a new `ResourceUrlProvider` to the WebFlux
configuration; this bean can be reused by the WebFlux infrastructure and
application code.
This also automatically configure this shared `ResourceUrlProvider`
instance on the resource chain where needed.
Issue: SPR-17433
Prior to this commit, `ResourceTransformerSupport.toAbsolutePath`
would call `StringUtils.applyRelativePath` in all cases. But this
implementation is prepending the given path even if the relative path
starts with `"/"`.
This commit skips the entire operation if the given path is absolute,
i.e. it starts with `"/"`.
Issue: SPR-17432
This commit fixes a memory leak in ServerSentEventHttpMessageWriter
that occurs when the input stream contains an error. Test added as well.
Issue: SPR-17419
Prior to this commit, the `ResourceUrlEncodingFilter` would wrap the
response and keep a reference to the request. When
`HttpServletResponse.encodeURL` is later called during view rendering,
the filter looks at the request and extracts context mapping information
in order to resolve resource paths in views.
This approach is flawed, when the filter is used with JSPs - if the
request is forwarded to the container by the `InternalResourceView`,
the request information is overwritten by the container. When the view
is being rendered, the information available in the request is outdated
and does not allow to correctly compute that context mapping
information.
This commit ensures that that information is being extracted from the
request as soon as the `ResourceUrlProvider` is set as a request
attribute.

The fix for SPR-17178 switched from debug to warn level warning for
all sub-classes of AbstractHandlerExceptionResolver where the request
concerned the DefaultHandlerExceptionResolver only.
This commit restores the original DEBUG level logging that was in
AbstractHandlerExceptionResolver from before SPR-17178. In addition
DefaultHandlerExceptionResolver registers a warnLogCategory by default
which enables warn logging and hence fulfilling the original goal
for SPR-17178.
Issue: SPR-17383
This reverts commit 162112.
Instead we'll go for a bigger rollback of the change from SPR-17178 so
that only DefaultHandlerExceptionResolver does warn logging by default.

This commit harmonizes the `HeadersAdapter` implementations across all
supported servers with regards to the `get(Object key)` contract; some
server implementations are not sticking to a `Map`-like contract and
return empty `List` instead of `null` when a header is not present.
This also fixes the `size()` implementations to reflect the number of
header keys, as some implementations consider multiple values for the
same header as different entries.
Issue: SPR-17396

Issue: SPR-16931
Tomcat and Jetty integration tests were moved out of spring-messaging
a very long time ago (before 4.0), but the dependencies remained
unnoticed until now.
Rather than formatting the expected value, and be susceptible to
minor formatting differences (e.g. 01 vs 1 for day of month), parse the
actual header value leniently with HttpHeaders and compare time values.
Issue: SPR-17330
If the content has not been consumed, cause it to be produced, and
wait for a certain amount of time before giving up, so the raw content
can be made available. This can occur when:
1) In a mock server scenario the Flux representing the client request
content is passed directly to the mock server request, but is never
consumed because of an error before the body is read.
2) Test obtains FluxExchangeResult (e.g. for streaming) but instead of
consuming the Flux, it calls getResponseBodyContent() instead.
Issue: SPR-17363
This commit adds special processing of some HTTP response headers in
Jetty and Tomcat; they both consider some headers like "Content-Length"
as specific and require explicit calls on the `HttpServletResponse`
itself on top of setting the HTTP response header.
Issue: SPR-17250
This commit avoids copying HTTP headers when mutating an HTTP request.
Instead, we're now unwrapping the `ReadOnlyHttpHeaders` (which is most
likely backed by the native request headers).
Issue: SPR-17250
Several benchmarks underlined a few hotspots for CPU and GC pressure in
the Spring Framework codebase:
1. `org.springframework.util.MimeType.<init>(String, String, Map)`
2. `org.springframework.util.LinkedCaseInsensitiveMap.convertKey(String)`
Both are linked with HTTP request headers parsing and response headers
writin during the exchange processing phase.
1) is linked to repeated calls to `HttpHeaders.getContentType`
within a single request handling. The media type parsing operation
is expensive and the result doesn't change between calls, since
the request headers are immutable at that point.
This commit improves this by caching the parsed `MediaType` for the
`"Content-Type"` request header in the `ReadOnlyHttpHeaders` class.
This change is available for both Spring MVC and Spring WebFlux.
2) is linked to insertions/lookups in the `LinkedCaseInsensitiveMap`,
which is the data structure behind `HttpHeaders`.
Those operations are creating a lot of garbage (including a lot of
`String` created by `toLowerCase`). We could choose a more efficient
data structure for storing HTTP headers data.
As a first step, this commit is focusing on Spring WebFlux and
introduces `MultiValueMap` implementations mapped by native HTTP headers
for the following servers: Tomcat, Jetty, Netty and Undertow.
Such implementations avoid unnecessary copying of the headers
and leverages as much as possible optimized operations provided by the
native implementations.
This change has a few consequences:
* `HttpHeaders` can now wrap a `MultiValueMap` directly
* The default constructor of `HttpHeaders` is still backed by a
`LinkedCaseInsensitiveMap`
* The HTTP request headers for the websocket HTTP handshake now need to
be cloned, because native headers are likely to be pooled/recycled by
the server implementation, hence gone when the initial HTTP exchange is
done
Issue: SPR-17250
Previously, if a DeferredImportSelector was identified at a later stage
as part of processing the collected set of deferred imports, such
selector was processed as a regular import selector.
Semantically, it makes sense as we already are in the deferred phase at
this point and it doesn't make much sense to bother about the extra
contract.
However, Spring Framework 5 introduced the notion of Group that a
deferred import selector can define. When it does, the container has to
honour the contract of the Group rather than calling the simpler
ImportSelector parent contract.
This commit restructures the processing of such case. When a deferred
import selector is detected while processing deferred import selectors,
a group is created with only that selector and the group API is invoked.

Spring Framework 5.1.0 exposed by mistake context in the Kotlin bean DSL

Headings are optimized for how they appear in the left-hand side
navitation menu, with context provided by parent headings, and not
necessarily for how they read on their own.
At 2nd and 3rd level of nesting, which is where most headings are,

sprawling.

This commit optimizes Flux <-> Mono conversions in our codebase by
avoiding to hide that conversion from Reactor.
This tries to keep conversions sequentially so that they can be detected
by Reactor and optimized. In Spring WebFlux, this means keeping the
conversions at the edges of a method implementation (right when getting
an input parameter, and before returning it as a result). If those
conversions are made between other operators, Reactor might not be able
to detect those conversions and optimize them.

When used as global Netty resources, ReactorResourceFactory creates and
sets those resources on Reactor's HttpResources directly.
When that ReactorResourceFactory bean is destroyed, those resources are
disposed but HttpResources still holds a reference to those and may try

references to it, when the ReactorResourceFactory is treating those as
global.

response body, it is properly drained when the response is closed to
make sure that the connection is released in a proper state and can be
put back in the connection pool for reuse.
Issue: SPR-17181
When dealing with `Optional` values in a Controller handler (for
example, values coming from a Spring Data repository), developers might
reuse this code snippet quite often:
```
@GetMapping("/user")
public ResponseEntity<Optional<User>> fetchUser() {
Optional<User> user = //...
return user.map(ResponseEntity::ok).orElse(notFound().build());
}
```
This commit adds a new static method on `ResponseEntity` for that,
simplifying the previous snippet with `return ResponseEntity.of(user);`
Note that in case more specific HTTP response headers are required by
the application, developers should use other static methods to
explicitly tell which headers should be used in each case.

Includes caching of declared annotation arrays and combined searching for several annotation types (used in SpringCacheAnnotationParser).
Issue: SPR-16933
Prior to this commit, if a test class was meta-annotated with multiple
@BootstrapWith declarations that registered different
TestContextBootstrapper implementations, such a configuration would
result in an IllegalStateException, and there was no way to override
this behavior.
This commit addresses this shortcoming by relaxing the explicit
TestContextBootstrapper resolution in BootstrapUtils so that a directly
present @BootstrapWith annotation will now override declarations of
@BootstrapWith that are meta-present. In other words, if @BootstrapWith
is used as a meta-annotation, it can be overridden directly on the test
class via an explicit, local declaration of @BootstrapWith.
Issue: SPR-17006
This commit handles "empty" cases for `ResponseEntity` controller
handler return types when wrapped with a `java.util.Optional` in Spring
MVC or a single `Publisher` like `Mono`.
Given the following example for Spring MVC:
```
@GetMapping("/user")
public Optional<ResponseEntity<User>> fetchUser() {
Optional<User> user = //...
return user.map(ResponseEntity::ok);
}
```
If the resulting `Optional` is empty, Spring MVC will infer a
`ResponseEntity` with an empty body and a 404 HTTP response status.
The same reasoning is applied to Spring WebFlux with Publisher types:
```
@GetMapping("/user")
public Mono<ResponseEntity<User>> fetchUser() {
Mono<User> user = //...
return user.map(ResponseEntity::ok);
}
```
This feature is only valid for `HttpEntity` return types and does not
apply to `@ResponseBody` controller handlers.

This commit introduces Protobuf support in WebFlux via dedicated
codecs.
Flux<Message> are serialized/deserialized using delimited Protobuf
messages with the size of each message specified before the message
itself. In that case, a "delimited=true" parameter is added to the
content type.
Mono<Message> are expected to use regular Protobuf message
format (without the size prepended before the message).
Related HttpMessageReader/Writer are automatically registered when the
"com.google.protobuf:protobuf-java" library is detected in the classpath,
and can be customized easily if needed via CodecConfigurer, for example
to specify protocol extensions via the ExtensionRegistry based
constructors.
Both "application/x-protobuf" and "application/octet-stream" mime types
are supported.
Issue: SPR-15776
Prior to this commit, controller handlers (regular and exception
handlers as well) would not overwrite existing HTTP response headers on
the exchange. This would lead to situations where Content-Type values
set during the initial handling phase would not be overwritten when
handling an error later on.
This commit aligns the implementation of that result handler on the
Spring MVC one in that regard.

Introduces getBeanProvider(Class) and getBeanProvider(ResolvableType), also narrowing getBean(String, Class) and isTypeMatch(String, Class) to a non-null Class argument and enriching NoUniqueBeanDefinitionException with a full ResolvableType. In addition, ObjectProvider supports iterable/stream access for collection-style resolution of multiple matching beans now, and collection injection falls back to an empty collection in a single-constructor case with non-null arguments.

Adds XML-based assertions in

Since SPR-15205, the `FormHttpMessageConverter` is adding a `charset`
directive to the `Content-Type` request header in order to help servers
understand which charset is being used to encode headers of each part.
As reported in SPR-17030 and others, some servers are not parsing
properly such header values and assume that `boundary` is the last
directive in the `Content-Type` header.
This commit reorders the charset information right before the boundary
declaration to get around those issues.
Issue: SPR-17030
Prior to this commit, the `DefaultClientResponse` implementation would
handle HTTP client cases where the server response body would need to be
consumed (pooled resources need to be released) and the body publisher
cancelled right away. This is done to avoid reading the whole response
body and returning the connection to the pool, now that this connection
cannot be reused.
This was done already when the `WebClient` is asked for a `Void` type
for the response body.
SPR-17054 brought a new case for that: whenever no message reader is
able to decode the response body, an `UnsupportedMediaTypeException`
error signal is sent. Prior to this commit, the response body would not
be consumed and cancelled for that case.
This commit refactors all those cases from the `DefaultClientResponse`
directly into the `BodyExtractors`, since most of the logic and
knowledge for that belongs there. We only need to only apply this
behavior when the HTTP client is involved, as the server does not want
this to happen.

Given "/{foo}" and "/a=42;c=b", previously that would be treated as a

Leverage https://github.com/jetty-project/jetty-reactive-httpclient
to add support for Jetty in WebClient via JettyClientHttpConnector.
Implemented with buffer copy instead of optimized buffer wrapping

releasing the buffer and requesting more data at different times
(required for Mono<DataBuffer> for example).
See https://github.com/eclipse/jetty.project/issues/2429.
Issue: SPR-15092
Prior to this commit, resolving an argument for a WebFlux controller
that's missing from the request and not required by the handler would
throw a NullPointerException in some cases.
This involves the conversion of the parameter (a `String` parameter type
might not trigger this behavior) and sending a `null` within a reactive
stream, which is illegal per the RS spec.
We now rely on a `Mono.justOrEmpty()` to handle those specific cases.

Like CookieLocaleResolver, LocaleChangeInterceptor parses both locale formats by default now. Since it does not need to render the locale, its languageTagCompliant property is not relevant anymore at all.

DefaultUriBuilderFactory now uses EncodingMode.TEMPLATE_AND_VALUES by

Prior to this commit, `WebClient` would throw `IllegalArgumentException`
when receiving an HTTP response with an unknown HTTP status code.
This commit is a follow up of SPR-16748 (supporting non-standard HTTP
status codes on the reactive `ClientHttpResponse`), and is mirroring
SPR-15978 (supporting non-standard HTTP status codes in `RestTemplate`).
With this change, `WebClient` now tolerates unknown status codes in some
cases, while not offering that choice as a first class citizen:
`HttpStatus` is still the preferred way to deal with HTTP status codes.
Here's how `WebClient` will behave when fetching the full response:
```
// Given a remote endpoint returning a "123" HTTP status code
Mono<ClientResponse> result = this.webClient.get()
.uri("/status/123")
.exchange();
// will still throw an IllegalArgumentException
HttpStatus status = result.block().statusCode();
// is safe and will return 123
int statusCode = result.block().rawStatusCode();
```
Resolving directly the response body with `retrieve()` is different.
```
// will send an error signal with a UnknownHttpStatusCodeException
Mono<String> result = this.webClient.get()
.uri("/status/123")
.retrieve()
.bodyToMono(String.class);
```
In general, `WebClient` will provide high-level support
for well-known HTTP status codes, like error handling with
`WebClient.ResponseSpec#onStatus`.
For such support with unknown status codes, it is better to rely
on lower level constructs such as `ExchangeFilterFunction`.

In SPR-16892, the `EncoderHttpMessageWriter` has been improved to write
`"Content-Length"` HTTP response headers if the response body is of type
`Mono` (i.e. the actual content length is easily accessible without
buffering a possibly large response body). That change was relying on
the fact that the server side is using a `ChannelSendOperator` to delay
the writing of the body until the first signal is received.
This strategy is not effective on the client side, since no such channel
operator is used for `WebClient`. This commit improves
`EncoderHttpMessageWriter` and delays, for `Mono` HTTP message bodies
only, the writing of the body so that we can write the
`"Content-Length"` header information once we've got the body resolved.
Issue: SPR-16949

This commit adds support for the "SameSite" attribute in response
cookies. As explained in rfc6265bis, this attribute can be used to limit
the scope of a cookie so that it can't be attached to a request unless
it is sent from the "same-site".
This feature is currently supported by Google Chrome and Firefox, other
browsers will ignore this attribute.
This feature can help prevent CSRF attacks; this is why this commit adds
this attribute by default for SESSION Cookies in WebFlux.

@PathVariable's javadoc states that it supports MultiValueMap
parameters (introduced by commit df0902), but by reading through the
code, that does not seem to be the case (compare, e.g.,
PathVariableMapMethodArgumentResolver to
RequestParamMapMethodArgumentResolver).
Moreover, parsing MultipleValueMap is done according to the ";"
character, and placing such a character in a path (e.g., consider
something like "/app/{param}/show" would just break the path.
This patch fixes PathVariable's javadoc by removing the mention of
MultiValueMap.
This commit fixes the write checks for
`ResourceRegionHttpMessageConverter`, which was previously not checking
properly the parameterized type (e.g. in case of a `List<Something>`).

Prior to this commit, the generated POMs for Spring Framework modules
would contain unneeded/harmful information from the Spring Framework
build:
1. The BOM imports applied to each module by the dependency
management plugin, for example for Netty or Reactor Netty.
Spring should not export that opinion to its POMs.
2. The exclusion of "org.slf4:jcl-over-slf4j" from *all* dependencies,
which made the POMs much larger than necessary and suggested to
developers that they should exclude it as well when using all those
listed dependencies. In fact, only Apache Tiles currently brings that
transitively.
This commit removes that information from the POMs.
The dependencyManagement Gradle plugin is disabled for POM generation
and we manually resolve the dependency versions during the generation
phase.
The Gradle build is streamlined to exclude "org.slf4:jcl-over-slf4j"
only when necessary.

After the Groovy 2.5 upgrade, the Spring Framework build on JDK9 hit
GROOVY-8631. Adding the relevant `jax-api` dependency to the module
didn't fix this issue. The Groovy release notes mention the use of the
`--add-modules` JVM flag, but this is not an option for this build which
should run on JDK8 -> JDK11.
This commit changes the dependency from `groovy-all` to more focused
dependencies on Groovy in the `spring-beans` and `spring-context`
modules. This change seems to avoid the automatic loading of Groovy
enhancements to JAXB (shipped with `groovy-xml`).

1. Consistent with "xml code" examples.
2. "xml()" is a static method and will use default builder config,
so use createXmlMapper(true) instead.
3. Fix mvc namespace tag typo.
Prior to this commit, the `AbstractMessageConverterMethodProcessor`
would fail to convert `InputStreamResource` to `ResourceRegion` as
expected, since the content length cannot be read without consuming the
stream. This is enforced by the `HttpRange` class.
Now the method processor would still try to output HTTP range response
headers to provide range support information. This step is using the
resource content length and reads the input stream, leading to
exceptions such as "IllegalStateException: InputStream has already been
read".
This commit improves the return type detection and excludes early
`InputStreamResource` return types. With those types, HTTP range support
is now completely disabled.
Issue: SPR-16754
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.

HandlerMethodReturnValueHandlerComposite and
AbstractMethodMessageHandler iterate using index over collections
implementing RandomAccess to avoid unnecessary iterators.
Using the simple example shown in the ticket but switching from

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).
Prior to this commit it was impossible to have an individual
constructor argument in a @Nested (i.e., inner) test class injected via
@Autowired, @Qualifier, or @Value.
This is due to a bug in javac on JDK versions prior to 9, whereby
annotation lookups performed directly via the
java.lang.reflect.Parameter API fail for inner class constructors.
Specifically, the parameter annotations array in the compiled byte code
for the user's test class excludes an entry for the implicit enclosing
instance parameter for an inner class constructor.
This commit introduces a workaround in ParameterAutowireUtils for this
off-by-one error by transparently looking up annotations on the
preceding Parameter object (i.e., index - 1). In addition, this commit
relies on the change recently introduced in MethodParameter in order to
compensate for the same JDK bug (see SPR-16652).
Issue: SPR-16653
In my opinion, we should parse ":{x}" style parameter as "x" is parameter using "NamedParameterUtils.parseSqlStatement",
so the condition "j - i > 2" is the correct condition, not "j - i > 3", because if "i" is the index of
":" in ":{x}", and "j" is the index of "}" in ":{x}", "j - i == 3" is true.
Also add a test case for SPR-16663.
This commit introduces tests for looking up annotations on parameters
in constructors for nested and inner classes via Spring's
MethodParameter abstraction.
The test for an inner class is currently disabled since it fails on
JDK 8. See JIRA issue for details.

This commit introduces @Nested tests to verify support for constructor

One of the tests is disabled on Java 8 due to a bug in javac that was
first fixed in JDK 9.
See https://github.com/junit-team/junit5/issues/1345 for details.
The prevailing current wisdom is to use the default constructor for
secure and let it pick the best algorithm for the OS.
On Java 8 (Oracle), Linux this results in "NativePRNG" which uses
/dev/random (potentially blocking) for the initial seed, and
/dev/urandom (non-blocking) for subsequent calls to nextInt.

Rather than create a new EvaluationContext instance per evaluation, we
now create a statically shared instance, without the root object in it,
and re-use it for all evalutations.
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:

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
This commit allows several DeferredImportSelector instances to be
grouped and managed in a centralized fashion. This typically allows
different instances to provide a consistent ordered set of imports to
apply.
Issue: SPR-16589
This commit picks up where SPR-14498 left off by adding support for an
explicit target type when using JsonPath to perform an assertion against
the response content using a Hamcrest Matcher.
Specifically, there is a new overloaded value(Matcher<T>, Class<T>)
method in JsonPathResultMatchers for use with Hamcrest matchers where
the target type (i.e., Class<T>) can be specified.
Issue: SPR-16587
With this change the code generation for method and property
references is modified to include branching logic in the
case of null safe dereferencing (?.). This is complicated
by the possible usage of primitives on the left hand side
of the dereference. To cope with this case primitives are
promoted to boxed types when this situation occurs enabling
null to be passed as a possible result.
Issue: SPR-16489
This commit restructures the existing content to separate out Overview
content into its own section, and also introduces more formal structure
where reference type content can be expanded over time.
Issue: SPR-16547
Prior to this commit, the `HttpEntityMethodProcessor` would check HTTP
conditions on non-safe requests (i.e. not GET/HEAD). This would prevent
Controllers from returning `ResponseEntity` containing response headers
with updated values of `"Last-Modified"` or `ETag` once the resource has
been updated.
This commit avoids those checks for non GET/HEAD requests - this code
can still be leveraged from Controllers themselves using
`ServletWebRequest::checkNotModified` methods.
Issue: SPR-15780
After send error, ignore calls to complete or completeWithError by the
application in the same thread (e.g. try-catch block), to avoid a
competing with an error callback from servlet container during which
the same action is taken.
Issue: SPR-16548
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
Includes related polishing in core.metadata and datasource.embedded and a revision of the corresponding database definitions in sql-error-codes.
Issue: SPR-16558
This commit makes sure that no `StringIndexOutOfBoundsException` is
thrown when `getForRequestUrl` is called with a URL that's shorter than
the expected context path.
Issue: SPR-16526
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.
Issue: SPR-16521
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 adds an Asciidoc anchor to the section on different injection
styles to be able to link to the discussion as official recommendation.
Closes gh-1681
As of 4.3.13 MappingJackson2MessageConverter uses the MethodParameter
hint to obtain generic type information but it needs to be careful, and
nest one level, if the target parameter type has a Message wrapper.
Issue: SPR-16486
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
Previously MockHttpServletRequestBuilder calculated the pathInfo from the
provided URL without decoding the value. This meant that the pathInfo
incorrectly included URL encoded values.
Now MockHttpServletRequestBuilder properly decodes the pathInfo.
Fixes: SPR-16453
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.

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.
