This commit ensures pathExtension predicate is skipped when the value
is null, in order to provide a more predictable behavior, and allow
a better compatibility with collections not supporting null elements
like the ones created by List#of.
Closes gh-32404
This commit adds support for application/yaml in MediaType and leverages
jackson-dataformat-yaml in order to support Yaml in RestTemplate,
RestClient and Spring MVC.
See gh-32345
webmvc.fn now also uses the StandardServletAsyncWebRequest wrapped response
to enforce lifecycle rules from Servlet spec (section 2.3.3.4).
See gh-32340
Also fix a couple of related issues:
- add AsyncRequestNotUsableException to the list of exceptions
that imply response issues.
- handle exceptions from @ExceptionHandler regardless of whether
thrown immediately or via Publisher.
Closes gh-32359
The JSP VariableResolver API has been deprecated since JSP 2.1 in favor
of the newer ELContext API.
This commit therefore refactors JspPropertyAccessor to use the
ELContext API.
Closes gh-32383
The following adjustments are also made as a result:
- Use int to check if lock is held and unlock is needed, given that
for non-async requests we don't need to obtain a lock.
- Protect access methods getOutputStream and getWriter with the
same locking and state checks.
Closes gh-32340
The wrapped response prevents use after AsyncListener onError or completion
to ensure compliance with Servlet Spec 2.3.3.4.
The wrapped response is applied in RequestMappingHandlerAdapter.
The wrapped response raises AsyncRequestNotUsableException that is now
handled in DefaultHandlerExceptionResolver.
See gh-32340
This commit introduces composite collections (i.e. Collection, Set, Map)
and uses these composites in request predicates, where before new
collections were instantiated.
Closes gh-32245
This commit checks whether the CompletableFuture<ServerResponse> passed
to AsyncServerResponse.async has been completed, and if so returns a
CompletedAsyncServerResponse that simply delegates to the completed
response, instead of the DefaultAsyncServerResponse that uses async
dispatch.
Closes gh-32223
Add helpers to CollectionUtils for building HashSets and LinkedHashSets
that can hold an expected number of elements without needing to
resize/rehash.
Closes gh-32291
Prior to this commit, the SseBuilder API in WebMvc.fn would only allow
to send Server-Sent Events with `data:` items in them. The spec doesnn't
disallow this and other specifications rely on such patterns to signal
the completion of a stream, like:
```
event:next
data:some data
event:complete
```
This commit adds a new `send()` method without any argument that sends
the buffered content (id, event comment and retry) without data.
Fixes: gh-32270
This commit introduces new HTTP method, Content-Type, and Accept header
request predicates that handle single values. Previously, these
predicates were always dealt with as single-value collections, which
introduced computational overhead.
Closes gh-32244
