This commit deprecates PathExtensionContentNegotiationStrategy and
ServletPathExtensionContentNegotiationStrategy and also updates code
that depends on them internally to remove that dependence.
See gh-24179
ContentNegotiationManagerFactoryBean now ensures that
ContentNegotiationManager contains the MediaType mappings even if the
path extension and the parameter strategies are off.
There are also minor fixes to ensure the media type mappings in
ContentNegotiationManagerFactoryBean aren't polluted when mapping keys
are not lowercase, and likewise MappingMediaTypeFileExtensionResolver
filters out duplicates in the list of all file extensions.
See gh-24179
Before this commit, the AbstractJackson2Encoder instantiated a
ObjectWriter per value. This is not an issue for single values or
non-streaming scenarios (which effectively are the same, because in the
latter values are collected into a list until offered to Jackson).
However, this does create a problem for SMILE, because it allows for
shared references that do not match up when writing each value with a
new ObjectWriter, resulting in errors parsing the result.
This commit uses Jackson's SequenceWriter for streaming scenarios,
allowing Jackson to reuse the same context for writing multiple values,
fixing the issue described above.
Closes gh-24198
As of gh-21783, Spring WebFlux uses a `TomcatHeadersAdapter`
implementation to directly address the native headers used by the
server.
In the case of Tomcat, "Content-Length" and "Content-Type" headers are
processed separately and should not be added to the native headers map.
This commit improves the `HandlerAdapter` implementation for Tomcat and
removes those headers, if previously set in the map. The adapter
already has a section that handles the Tomcat-specific calls for such
headers.
Fixes gh-24361
Previously, anyone could publish a scan and publishing was performed
if the GRADLE_ENTERPRISE_URL environment variable was set.
ge.spring.io has now been locked down to prohibit anonymous build scan
publishing. This commit aligns with this change by only attempting to
publish a build scan when authenticated with the server.
Authentication is achieved via an access token that is made available
via an environment variable on CI and locally via a file in ~/.gradle.
One can obtain an access key by running the following command:
./gradlew provisionGradleEnterpriseAccessKey
Closes gh-24371
The case of one data buffer containing multiple lines can could cause
a buffer leak due to a suspected issue in concatMapIterable. This
commit adds workarounds for that until the underlying issue is
addressed.
Closes gh-24339
This commit updates CORS support in order to check Origin header
in CorsUtils#isPreFlightRequest which does not change how Spring
MVC or WebFlux process CORS request but is more correct in term
of behavior since it is a public API potentially used in another
contexts.
It also removes an unnecessary check in
AbstractHandlerMethodMapping#hasCorsConfigurationSource and processes
every preflight request with PreFlightHandler.
Closes gh-24327
