Prior to this commit, the `RestTemplate` `ClientHttpObservation` would
be started before the request object is available. While this would also
measure the connection estalishment for some HTTP client libraries, this
arrangement is incompatible with a tracing approach where the request
must be available to propagate information through the request headers.
This commit ensures that the observation only starts when the request is
available.
Fixes gh-29234
Prior to this commit, the HTTP Observations would use
`HttpStatus.Series` as a value source for the "outcome" key value in
recorded observations. This would work for most cases, but would not
align in the 2xx HTTP status cases: the series would provide a
"SUCESSFUL" value whereas the heritage metrics support in Spring Boot
would give "SUCESS".
This commit introduces a dedicated `HttpOutcome` concept for this and
applies it to all HTTP observations.
Fixes gh-29232
This commit ensures that all HTTP `ObservationConvention`
implementations provide a consistent contextual name for observations.
This name should be like "http get" where only the HTTP verb changes
depending on the request.
Fixes gh-29231
This commit also temporarily changes a test assertion for the Jackson
Kotlin module.
As of https://youtrack.jetbrains.com/issue/KT-52932, Kotlin enhanced the
`IntRange` and this change is not supported yet by the Jackson Kotlin
module. An issue has been reported here:
FasterXML/jackson-module-kotlin#582
Closes gh-29225
Improve ResponseCookie to allow an existing instance to be mutated
and also to set the cookie value through the builder. This allows
CookieLocaleResolver to avoid duplicating all the fields of
ResponseCookie and to have only a ResponseCookie field instead.
Closes gh-28779
At present, CookieLocaleResolver extends CookieGenerator instead of
AbstractLocale(Context)Resolver like other LocaleResolver
implementations. This means it duplicates some common aspects of
LocaleResolver hierarchy while also exposing some CookieGenerator
operations, such as #addCookie and #removeCookie.
Additionally, CookieGenerator's support for writing cookies is based
on Servlet support which at current baseline doesn't support SameSite
directive.
This commit refactors CookieLocaleResolver to make it extend
AbstractLocaleContextResolver and also replaces CookieGenerator's
cookie writing support with newer and more capable ResponseCookie.
Simplify creation of CookieLocaleResolver with custom cookie name
This commit introduces CookieLocaleResolver constructor that accepts
cookie name thus allowing for a simpler creation of an instance with
the desired cookie name.
See gh-28779
This commit isolates the invocation of Kotlin coroutines into a separate
template method, so that it can be overridden in subclasses of
RequestMappingHandlerAdapter.
Closes gh-27195
Prior to this commit, `ServletContextResource` could rely on
`ServletContext#getRealPath` to check whether a resource exists.
This behavior is not enforced on some Servlet containers, as this method
is only meant to translate virtual paths to real paths, but not
necessarily check for the existence of the file.
See https://bz.apache.org/bugzilla/show_bug.cgi?id=55837#c3 for a
rationale of this behavior in Tomcat.
This commit enforces an additional check, resolving the path as a `File`
and checking that is exists and is a file.
Closes gh-26707
In general, `Stream#toList()` is not a transparent replacement for
`.collect(Collectors.toList()))`, as the former returns an immutable
list.
This commit reverts some of those changes, where the returned `List`
instance was expected to be mutable.
See gh-29203
After gh-29068, some Type instances can throw an
IllegalArgumentException. This commit catches them
properly to just return a null serializer in that
case.
Closes gh-29192
This commit removes the scoping of `RestTemplate` requests, since no
user code is meant to run during HTTP client exchanges.
This also polishes the reactive `WebFilter` to directly use the
specific enum when creating the observation.
Prior to this commit, resource management around
`ClientHttpRequestFactory` and `RestTemplate` was unclear. Some
factories implementation were implementing a `DisposableBean` and other
contracts were not managing request factory resources.
In the meantime, neither `ClientHttpRequestFactory` nor `RestTemplate`
are typically meant to be contributed as beans to the application
context. Most often, they're instantiated within beans and their
lifecycle should be managed by those.
This commit makes all `ClientHttpRequestFactory` `Closeable` and ensures
that all existing implementations have a similar behavior between
`dispose()` and `close()`. Since `RestTemplate` (actually
`HttpAccessor`) can instantiate factories on its own, they also now
extend `Closeable` to properly close those resources, if not externally
managed.
Closes gh-29010
This commit introduces a `HttpRequestsObservationWebFilter` which
instruments web frameworks using Spring's reactive `ServerHttpRequest`
and `ServerHttpResponse` interfaces.
This replaces Spring Boot's `MetricsWebFilter`.
