This commit introduces the following changes.
1) It adds a new Spring @NonNull annotation which allows to apply
@NonNullApi semantic on a specific element, like @Nullable does.
Combined with @Nullable, it allows partial null-safety support when
package granularity is too broad.
2) @Nullable and @NonNull can apply to ElementType.TYPE_USE in order
to be used on generic type arguments (SPR-15942).
3) Annotations does not apply to ElementType.TYPE_PARAMETER anymore
since it is not supported yet (applicability for such use case is
controversial and need to be discussed).
4) @NonNullApi does not apply to ElementType.FIELD anymore since in a
lot of use cases (private, protected) it is not part for the public API
+ its usage should remain opt-in. A dedicated @NonNullFields annotation
has been added in order to set fields default to non-nullable.
5) Updated Javadoc and reference documentation.
Issue: SPR-15756
When writing Publisher<Publisher<T>>, a flush operation is performed onComplete
for every Publisher. If the flush operation is not able to be performed immediately
it will be retried before starting to process data provided by the next Publisher.
For the last Publisher the implementation needs to ensure that the flush will
be performed only then whole operation will complete.

This commit introduces a ForwardedHeaderFilter for WebFlux, similar to
the existing Servlet version. As part of this the
DefaultServerHttpRequestBuilder had to be changed to no longer use
delegation, but instead use a deep copy at the point of mutate().
Otherwise, headers could not be removed.
Issue: SPR-15954
Now that https://github.com/reactor/reactor-netty/issues/138 is solved,
this commit removes the temporary workaround introduced in SPR-15784
but leaves the general mechanism for detecting empty responses.
The high level matchStarting API was removed a few commits ago.
This change tidies up by removing the supporting infrastructure
for that from the PathElements.
InMemoryWebSessionStore is very closely associated to DefaultWebSession
passing it to it several fields and functions. Now that the store also
creates the session, it makes sense to bring the latter in as an inner,
nested class.
Issue: SPR-15875, 15876
DefaultWebSessionManager no longer requires the WebSessionStore
to use DefaultWebSession.
Removed explicit start() in save(). This seemed unnecessary since at
that point isStarted is guaranteed to return true. The status can
be updated through the copy constructor.
DefaultWebSessionTests added.
Issue: SPR-15875
- Add WebSessionStore.createWebSession.
- Remove remove WebSessionStore.changeSessionId
- Add WebSessionStore updateLastAccessTime which allows updating the
WebSession lastAccessTime without exposing a method on WebSession in
an implementation independent way.
- Remove WebSessionStore.storeSession. This method is not necessary
since the WebSession that is returned allows saving the WebSession.
Additionally, it is error prone since the wrong type might be passed
into it.
Issue: SPR-15875, 15876
Add missing DefaultWebSessionManagerTests .block(). Previously
session.save() was invoked, but we did not ensure it was completed.
This commit makes it block on session.save()
Fix existingSessionIsExpired. This test is actually broken and is
testing a new session is created because the session id returned
by the idResolver does not match the existing WebSession.
This commit ensures that the id of the WebSession found by idResolver
matches the existing WebSession.
DefaultWebSessionManagerTests use Mockito. To ensure we test with
independence from InMemoryWebSessionStore we use Mockito for the
DefaultWebessionManager collaborators.
Add test for response.setComplete(). We want to ensure that when the
response is completed, it saves the WebSession and writes it to the
response using idResolver
Use constant for default header name and make getHeaderName private.
Also switch HeaderWebSessionIdResolverTests to unit tests rather than
testing with DefaultWebSessionManager.
Issue: SPR-15917
Before this commit, there was no way to signal the HTTP client that we
were done consuming the response. Without that, the underlying client
library cannot know when it is safe to release the associated resources
(e.g. the HTTP connection).
This commit adds new `close()` methods on both `ClientHttpResponse`
and `ClientResponse`. This methods is non-blocking and its behavior
depends on the library, its configuration, HTTP version, etc.
At the `WebClient` level, `close()` is called automatically if we
consume the response body through the `ResponseSpec` or the
`ClientResponse` itself.
Note that it is *required* to call `close()` manually otherwise; not
doing so might create resource leaks or connection issues.
Issue: SPR-15920
This commit moves `encodeUrl` and `registerUrlEncoder` from
ServerHttpResponse to ServerWebExchange.
It also renames `encodeUrl` to `transformUrl` and `registerUrlEncoder`
to `addUrlTransformer` to make it clearer that these methods do not
perform actual URL encodings (i.e. they do not replaceinvalid
characters).
The `add` prefix (instead of `register`) makes it clearer that each
function is added in addition to the previous one.
Issue: SPR-15924
Introduces HeaderSessionIdResolver, which reads session ids from a session header and generates a session response header when new session are created.
Related issue: SPR-15917
`ReactorClientHttpConnector` provides an adapter layer to `WebClient`
for using Reactor-Netty's `HttpClient`.
This commit enables HTTP compression support by default for this client
Connector.
Another constructor is still available for providing a custom
`HttpOptions` configuration.
Issue: SPR-15908
Bean-derived null values may still get passed into bean properties and injection points but only if those are declared as non-required. Note that getBean will never return null; a manual bean.equals(null) / "null".equals(bean.toString()) check identifies expected null values now. This will only ever happen with custom FactoryBeans or factory methods returning null - and since all common cases are handled by autowiring or bean property values in bean definitions, there should be no need to ever manually check for such a null value received from getBean.
Issue: SPR-15829
The PathPattern compareTo method is now consistent with equals when
two patterns are of the same specificity but otherwise different.
Separately PathPattern now exposes a Comparator by specificity that
offers the current functionality of compareTo. This can be used for
actual sorting where we only care about specificity.
Consistent behavior with matches(PathContainer), the two had slightly
different logic for handling of empty paths.
Make matchAndExtract independantly usable without the need to call
matches(PathContainer) first. Essentially no longer raising ISE if the
pattern doesn't match but simply returning null.
