Prior to this commit, the Observation instrumentation for Reactive
server applications was implemented with a `WebFilter`. This allowed to
record observations and set up a tracing context for the controller
handlers.
The limitation of this approach is that all processing happening at a
lower level is not aware of any observation. Here, the
`HttpWebHandlerAdapter` handles several interesting aspects:
* logging of HTTP requests and responses at the TRACE level
* logging of client disconnect errors
* handling of unresolved errors
With the current instrumentation, these logging statements will miss the
tracing context information. As a result, this commit deprecates the
`ServerHttpObservationFilter` in favor of a more direct instrumentation
of the `HttpWebHandlerAdapter`. This enables a more precise
instrumentattion and allows to set up the current observation earlier in
the reactor context: log statements will now contain the relevant
information.
Fixes gh-30013
This commit improves how the build deals with javadoc invalid references
in two ways.
Link/see references that are temporarily invalid during javadoc
generation of individual modules are better masked by using the option
`Xdoclint:syntax` instead of `Xdoclint:none` (warnings were still
visible in some cases, e.g. when individually building the javadoc for
a specific module).
Global javadoc-building task `api` now combines `syntax` and `reference`
`Xdoclint` groups, allowing to raise truly invalid references even when
all the modules have been aggregated.
This commit also fixes the 20+ errors which appeared following the later
change in doclet configuration.

ServletContext has sets of major/minor version properties that we have
not updated in MockServletContext in several years.
Since we upgraded the baseline to Servlet 6.0 in Spring Framework 6.0,
now seems like a good time to update those version properties.

* use forEach and putIfAbsent to copy headers in DefaultClientRequestBuilder
* use forEach in ReactorClientHttpRequest and ReactorNetty2ClientHttpRequest
* circumvent ReadOnlyHttpHeaders.entrySet()
* ensure the fast path to LinkedCaseInsensitiveMap for forEach and putIfAbsent exists

This commit adds support for the @XmlSeeAlso annotation in the
Jaxb2XmlDecoder. This includes
- Finding the set of possible qualified names given a class name, rather
than a single name.
- Splitting the XMLEvent stream when coming across one of the names in
this set.
Closes gh-30167
This commit polishes an external contribution, ensuring that not just
spaces are encoded as underscores, and that underscores are encoded
as non-printable.

This commit refactors some AssertJ assertions into more idiomatic and
readable ones. Using the dedicated assertion instead of a generic one
will produce more meaningful error messages.
For instance, consider collection size:
```
// expected: 5 but was: 2
assertThat(collection.size()).equals(5);
// Expected size: 5 but was: 2 in: [1, 2]
assertThat(collection).hasSize(5);
```
Closes gh-30104
This commit turns some stream-based iterations back into simpler
enhanced for loops.
For simple use cases like these, where the stream API is merely used to
map/filter + collect to a List, a for loop is more efficient.
This is especially true for small collections like the ones we deal
with in BodyInserters/BodyExtractors here (in the order of 50ns/op vs
5ns/op). These cases are also simple enough that they don't lose in
readability after the conversion.

This commit ensures that the HttpMethod, exposed through
ServerHttpRequest::getMethod, is cached in AbstractServerHttpRequest so
that potentially expensive HTTP method lookups are only done once.
Closes gh-30139
This commit picks up where the two previous commits left off.
Specifically, this commit:
- Removes the "severity=warning" configuration to ensure that violations
actually fail the build.
- Fixes regular expressions for suppressions by matching forward
slashes using `[\\/]` instead of `\/`.
- Moves the configuration for newly introduced checks to locations in
checkstyle.xml that align with the existing organization of that file.
- Renames the IDs for RegexpSinglelineJava checks from
javaDocPackageNonNullApiAnnotation/javaDocPackageNonNullFieldsAnnotation
to packageLevelNonNullApiAnnotation/packageLevelNonNullFieldsAnnotation,
respectively, since these checks are not related to Javadoc.
- Simplifies the null-safety annotation checks to match against
imported annotation types, which enforces consistency across
package-info.java files for the annotation declarations.
- Simplifies the RegEx for JavadocPackage suppressions to only exclude
packages not under src/main/java (vs src/main) and those in the
framework-docs module.
- Consistently suppresses all checks for the `asm`, `cglib`, `objenesis`,
and `javapoet` packages in spring-core.
- Adds explicit suppressions for null-safety annotations for the `lang`
package in spring-core.
- Adds explicit suppressions for null-safety annotations for the
`org.aopalliance` package in spring-aop.
- Revises the RegEx for null-safety annotation suppressions to only
exclude package-info.java files not under src/main/java and
additionally to exclude package-info.java files in the framework-docs
module as well as those in the spring-context-indexer,
spring-instrument, and spring-jcl modules.
- Adds all missing package-info.java files.
- Adds null-safety annotations to package-info.java files where
appropriate.

If content-length is available, pass it to readNBytes in
ByteArrayHttpMessageConverter. When the content length is less than
the internal buffer size in InputStream (8192), this avoids a copy,
as readNBytes will return the buffer directly. When the content length
is greater than the buffer size used in InputStream, passing the
content-length at least avoids over-allocating the final buffer (e.g.,
if the content length were 8193 bytes, 1 byte more than the default
buffer size).
If the content length isn't present or is too large to represent as
an integer, fall back to the default behavior of readAllBytes by
passing in Integer.MAX_VALUE.

HttpServiceProxyFactoryExtensions.kt has been mistakenly created
in spring-webflux module instead of spring-web, breaking JPMS for
WebFlux users.
This commit moves this file and related tests to the spring-web
module.

This commit ensures that WebFlux's RequestMethodsRequestCondition
supports HTTP methods that are not in the RequestMethod enum.
- RequestMethod::resolve is introduced, to convert from a HttpMethod
(name) to enum values.
- RequestMethod::asHttpMethod is introduced, to convert from enum value
to HttpMethod.
- HttpMethod::valueOf replaced Map-based lookup to a switch statement
- Enabled tests that check for WebDAV methods

This commit refines ModelAttributeMethodProcessor Kotlin exception
handling in order to throw a proper MethodArgumentNotValidException
instead of a NullPointerException when Kotlin null-safety constraints
are not fulfilled, translating to an HTTP error with 400 status code
(Bad Request) instead of 500 (Internal Server Error).
Closes gh-23846
MethodArgumentTypeMismatchException and
MethodArgumentConversionNotSupportedException are TypeMismatchException

This commit introduces DataBuffer::readableByteBuffers and
DataBuffer::writableByteBuffers, allowing restricted access to the
ByteBuffer used internally by DataBuffer implementations.
Closes gh-29943
Includes small refactoring in DefaultServerWebExchange and adjustment
of initMultipartData to get involved for any "multipart/" prefixed
media type.
In addition, "multipart/related" is now in the list of media types
supported by FormHttpMessageConverter, which aligns it with
MultipartHttpMessageReader.
