Prior to this commit, a cancelled exchange would always result in an
`"status":"UNKNOWN"` KeyValue. This only applied to reactive variants,
as cancelled exchanges are not currently detected for Servlet
implementations.
In some cases, exchanges can be cancelled by clients before they are
completed, but the response was actually received by the client. The
response status information has been set by the application and the
response has been committed. For those cases, we shouldn't assume an
"UNKNOWN" value.
This commit assumes that committed responses have a response status set
by the application and that the observations should reflect that. From
now on, we only assume an "UNKNOWN" status if the response has not been
commited.

This commit adds a constructor with externally managed
Reactor Netty resources to ReactorNettyClientRequestFactory
and makes it lifecycle-aware in order to support Project CRaC.
Closes gh-31280
Closes gh-31281
This commit replaces uses of onErrorResume() with
- onErrorMap() in places where onErrorResume() is just used to map to a
different exception.
- onErrorComplete() where onErrorResume() just maps to Mono.empty().
- onErrorReturn() where onErrorResum() just maps to Mono.just().
Closes gh-31352
This commit ensures that both `ObservationRegsitry` and
`ServerRequestObservationConvention` beans are automatically detected in
the application context if they are unique. This aligns with the
existing behavior for all other builder methods.
Closes gh-31205
With this commit, ReactorClientHttpConnector now implements
SmartLifecycle which optionally allows recreating the HttpClient
after ReactorResourceFactory has been updated.
Closes gh-31180
With this commit, ReactorResourceFactory now implements
Lifecycle which allows supporting JVM Checkpoint Restore
in Spring Boot with Reactor Netty server, and helps
to support Reactor Netty client as well.
Closes gh-31178
Prior to this commit, the `RestTemplateAdapter` would manually expand
templated URIs. This means that the `RestTemplate` instance itself would
never see the templated URIs and could not record it in the client
observations at runtime.
This commit ensures that when URI templates are available, the adapter
uses the correct `exchange` method variant.
Fixes gh-31144
This commit builds on the recently added support for using @AliasFor to
override the `value` attribute in `@Component, and allows a custom
component name to be specified in both @ControllerAdvice and
@RestControllerAdvice via new `name` attributes.
See gh-31089
Closes gh-21108
This commit instruments the new `RestClient` HTTP client for
observability. Since this client is sharing its HTTP infrastructure with
`RestTemplate` and operates on the same request/response types, this
instrumentation reuses the Observation convention and context.
This choice makes sense since one can build a new `RestClient` instance
using a `RestTemplate` instance, effectively reusing the underlying
configuration.

When the content length is known, use readNBytes on the InputStream in
StringHttpMessageConverter, which avoids some extra copying and allocations.
