Reduce the number of times capacity growth is needed inside the StringWriter.
A typical default SpringBoot Prometheus page has more than 11k characters.
Best performance results when no capacity growth is needed at all, so base
it on previous metrics page size plus some room for possible extra metric info.
See gh-30085
Previously the parameters were not ignored so */*;q=0.8 was not
identified as accepting */*. As a result, the most recent producible
content type was returned rather than the default.
This commit updates the argument resolver to ignore parameters.
The default content type is now produced in response to a request
that accepts */*, irrespective of its parameters.
Fixes gh-28446
Change the cache in `CachingOperationInvoker` to be a reference based
map and also clean stale entries when a specific threshold is met.
Fixes gh-28313
Update Prometheus `TextOutputFormat` so that OpenMetrics is used in
preference to text output when an appropriate accept header is found.
If the accept header contains `*/*` or is missing then the text format
will be used.
See gh-28130
Add an `isDefault()` method to `Producible` which can be used to
indicate which of the enum values should be used when the accept header
is `*/*` or `null`.
Prior to this commit, the last enum value was always used as the
default.
See gh-28130
Previously, the URI template handler installed by the client metrics
interceptor would always capture the URI template and push it onto the
deque, irrespective of whether auto timing was enabled. When
auto-timing is disabled the deque is never polled so this led to its
unrestricted growth.
This commit updates the URI template handler so that a URI template is
only pushed onto the deque when the auto timing configuration enables
the interceptor.
Fixes gh-26915
Change `CompositeHealth.getDetails()` to public so that it serializes
correctly when `MapperFeature.CAN_OVERRIDE_ACCESS_MODIFIERS` is
disabled.
Fixes gh-26797
Rework existing `@Timer` annotation support to remove duplicate code
and offer general purpose utilities that can be used in future metrics
support.
See gh-23112
See gh-22217
Extract common method logic to a `HandlerMethodTimedAnnotations`
utility class and also add some caching. Also move the test code
into a single class.
