Update the `HealthEndpointGroups` customization support to use a
post-processor rather than a mutable registry. Although this approach
is slightly less flexible, it removes a lot of complexity from the
`HealthEndpointGroups` code. Specifically, it allows us to drop the
`HealthEndpointGroupsRegistry` interface entirely.
The probe health groups are now added via the post-processor if they
aren't already defined. Unlike the previous implementation, users are
no longer able to customize status aggregation and http status code
mapping rules _unless_ they also re-define the health indicators that
are members of the group.
See gh-20962
Update `AvailabilityProbesAutoConfiguration` to allow the
`management.health.probes.enabled` property to override the platform
detection logic. Prior to this commit, it was possible to use the
property to enable the probes, but it was not possible to disable
them when deploying to Kubernates.
See gh-20962
Relocate probe auto-configuration from the `kubernetes` package to
`availability` since probes could also be used on other platforms.
The classes have also been renamed to named to `AvailabilityProbes...`
See gh-20962
Rename `LivenessProbeHealthIndicator` to `LivenessStateHealthIndicator`
and `ReadinessProbeHealthIndicator` to `ReadinessStateHealthIndicator`.
Also introduce a general purpose `AvailabilityStateHealthIndicator`
class.
See gh-20962
Create a general purpose `AvailabilityState` interface and refactor
the existing `LivenessState` and `ReadinessState` to use it. A single
`AvailabilityChangeEvent` is now used to carry all availability state
updates.
This commit also renames `ApplicationAvailabilityProvider` to
`ApplicationAvailabilityBean` and extracts an `ApplicationAvailability`
interface that other beans can inject. The helps to hide the event
listener method, which is really internal.
Finally the state enums have been renamed as follows:
- `LivenessState.LIVE` -> `LivenessState.CORRECT`
- `ReadinessState.READY` -> `ReadinessState.ACCEPTING_TRAFFIC`
- `ReadinessState.UNREADY` -> `ReadinessState.REFUSING_TRAFFIC`

Prior to this commit, the Undertow compression configuration provided by
Spring Boot would fail and throw an exception for invalid MIME Types
when trying to check them against the list of configured types for
compression.
This commit ensures that invalid MIME Types are ignored and that
compression is disabled for those.
Fixes gh-20955
With its initial fix in gh-18444, the `WebClient` instrumentation would
record all CANCEL signals, including:
* when a `timeout` expires and the response has not been received
* when the client partially consumes the response body
Since the second use case is arguable intentional, this commit restricts
the instrumentation and thus avoids recording two events for a single
request in that case.
Closes gh-18444
Prior to this commit, cancelled client requests (for example as a result
of a `timeout()` reactor operator would not be recorded by Micrometer.
This commit instruments the cancelled signal for outgoing client
requests and assigns a status `CLIENT_ERROR`.
The cancellation can be intentional (triggering a timeout and falling
back on a faster alternative) or considered as an error. The intent
cannot be derived from the signal itself so we're considering it as a
client error.
Closes gh-18444
Prior to this commit, the `HttpHandlerAutoConfiguration` would rely on
the `WebFluxProperties` bean being present - this is most of the time
true when the appplication is using the WebFlux auto-configuration.
If the application is overriding the WebFlux auto-configuration and
providing its own setup, the properties bean is not present and we
should skip its usage.
Fixes gh-20891
This commit removes the duplication added temporarily in Spring Boot to
initialize a default WavefrontSender builder.
This commit also disables a test is failing at the moment, see
https://github.com/micrometer-metrics/micrometer/issues/1964
See gh-20854
Prior to this commit, processing of multiple properties files
discovered using a wildcard pattern would stop on any error
encountered while processing a file or when an empty properties file
was found, causing subsequent files from the pattern to be ignored.
This commit changes the behavior such that subsequent files are
processed on error or on an empty file.
Fixes gh-20873
Rename the SAML `singleSignOn` nested property to `singleSignOn` so
that we don't get problems when using uppercase environment variable
names.
See gh-20584
Rework the rename logic used to include the reference PDF to try
and workaround the following local build error:
Encountered duplicate path "reference/pdf/spring-boot-reference.pdf"
during copy operation configured with DuplicatesStrategy.FAIL
See gh-20829
This commit adds examples for configuring the default builder to use
an HTTP/HTTPS proxy when building OCI images using the Maven or Gradle
plugin.
Fixes gh-19984
This commit combines index adoc files for single-page HTML and PDF
into one file to remove duplication. It also renames index files to
reflect the separation between source format and generated output
format.
Finishes gh-20829
ExecutableArchiveLauncher.createClassLoader(Iterator) calls
createClassLoader(URL) method with 'super'. This means overriding
createClassLoader(URL) is not possible without also overriding
createClassLoader(Iterator). The switch to 'this' enables that.
See gh-20851
This commit upgrades the Wavefront metrics export auto-configuration to
provide a `WavefrontSender` if necessary and use that to export metrics
rather than the http client Micrometer used previously.
As a result, the "read-timeout" and "connect-timeout" properties are no
longer honoured.
Closes gh-20810
StatsD no longer publishes metrics about itself and StatsDMetrics is
deprecated as a result. This commit removes the auto-configuration of
it.
Closes gh-20836
This commit exposes an additional property for Graphite that allows to
restore the previous default behaviour with regards to tags, i.e.
prefixing the ones defined by the "tagsAsPrefix" property.
Close gh-20834
This property is a left-over and was never used in Micrometer so this
commit deprecates its use so that it can be removed in the next feature
release.
Closes gh-20835
This commit fixes the AtlasProperties hierarchy so that it no longer is
a StepRegistryProperties. The AtlasConfig on the Micrometer side of
things does not share the common config hierarchy either and some
properties have different default and lifecycle.
Closes gh-20843
This commit moves Maven plugin content from several sections in the
main Spring Boot reference documentation to the plugin-specific
documentation.
