Prior to this commit, the `DefaultWebClient` would execute the configured
`ExchangeFilterFunction` as the reactive pipeline is assembled during
subscription. This means that if imperative code is executed in a filter
function, it won't be aware of the current observation through the local
scope.
For example, when automatic context propagation is enabled for Reactor
operators, the logger MDC will not know about the current
traceId/spanId.
This commit ensures that client filter functions execution is deferred
during the actual client exchange.

Prior to this commit, the HttpComponents implementation for the
`WebClient` would only consider the max-age attribute of response
cookies when parsing the response. This is not aligned with other client
implementations that consider the max-age attribute first, and then the
expires if the former was not present. The expires date is then
translated into a max-age duration. This behavior is done naturally by
several implementations.
This commit updates the `HttpComponentsClientHttpResponse` to do the
same.
Fixes gh-33157
Prior to this commit, `MimeMessageHelper` would accept `Resource`
instances as inline attachments in multipart MIME messages. If the
provided `Resource` implementation returns `null` for `getFileName()`,
the `addInLine` method would fail with a `NullPointerException` as
Jakarta activation fails to detect the content type for a null filename.
This commit falls back on "application/octet-stream" when the filename
is not known for the given resource instead of failing with an
exception.
Fixes gh-33527
Prior to this commit, the URL handler mapping would expose the matching
pattern, the path within mapping and matching URI variables as request
attributes. This was the case when the mapping would use the
`AntPathMatcher` as matching infrastructure, but not when using the
`PathPattern` variant. In this case, the map of URI variables would be
`null`. This could throw `IllegalArgumentException` when `RedirectView`
instances were relying on the presence of specific variables.
This commit ensures that URI variables are also extracted when the
`PathPatternParser` is used.
Fixes gh-33422
The previous pointcut attempted to match against a local lambda type;
however, that pointcut was unreliable and failed sporadically.
This commit therefore changes the pointcut so that it specifically
targets the get() method of a subtype of Supplier, which seems to result
in reliable pointcut matching.
Prior to this commit, the `ServerHttpObservationFilter` was fixed to
re-enable instrumentation for async dispatches. This fix involves using
an AsyncListener to be notified of exchange completion.
This change was incomplete, as this would not work in some cases.
If another filter starts the async mode and initiates an ASYNC dispatch,
before async handling at the controller level, the async listener is not
registered against subsequent async starts.
This commit not only ensures that the async listener registers
against new async starts, but also ensure that the initial creation and
registration only happens during the initial REQUEST dispatch.
Fixes gh-33451
This commit updates the Evaluation chapter to reflect the following.
- SimpleEvaluationContext no longer has a create() method. Instead it
has forPropertyAccessors(), forReadOnlyDataBinding(), and
forReadWriteDataBinding() factory methods.
- SpEL cannot automatically create missing array elements or grow the
size of an array like it can for a collection.
Closes gh-33456
Prior to this commit, the main() method attempted to retrieve a
TransferService bean from the context, but no such bean had been
configured in the context.
This commit addresses that by configuring a TransferService bean in the
context.
Closes gh-33446
Prior to this commit, the `RestClient` instrumentation would create and
close observations for HTTP requests, but would not open an observation
scope for the lifetime of the exchange.
This means that custom `ClientHttpRequestInterceptor` and
`ResponseErrorHandler` would not get access to the current observation
scope in case of tracing, possibly leading to missing trace ids in logs.
This commit ensures that an observation scope is managed for the
lifetime of the HTTP exchange.
