This avoids "IllegalStateException: Expectations already declared" when
a MockRestServiceServer is used after one request throws an exception.
Issues: SPR-16132
This commit decouples ExchangeResult from knowledge about
WiretapClientHttpRequest/Response both of which are now private to
WiretapConnector.
ExchangeResult takes ClientHttpRequest/Response instead along with
promises for the serialized request and response content in the form
of MonoProcessor<byte[]>.
This sets up the possibility for an ExchangeResult to be created
outside and independent of WebTestClient, should we decide to make its
constructor public.
Issue: SPR-16101
MockMvc now properly detects the presence of an AsyncContext and
re-uses the response instance used to start it.
This commit also includes a minor fix in
ResponseBodyEmitterReturnValueHandler to ensure it does not disable
ETag related content buffering for reactive return values that do not
result in streaming (e.g. single value or collections).
Issue: SPR-16067
The WebTestClient now takes advantage of the support for decoding
response to Void.class in WebClient so that applications can use
expectBody(Void.class) to the same effect as using
response.bodyToMono(Void.class) as documneted on WebClient#exchange.
The top-level, no-arg returnResult method (added very recently) has been
retracted, since the use of returnResult at that level, i.e. without
consuming the response content, should be used mainly for streaming.
It shouldn't be used for "no content" scenarios.
Documentation and Javadoc have been udpated accordingly.
Use the ClientResponse methods bodyToMono and bodyToFlux rather than
passing in a BodyExtractor so that WebTestclient now also benefits from
the recently improved handling of Void.class.
Concrete server and client, reactive request and response
implementations should not have to be accessed outside their package.
They could be seen as private to their HttpHandler adapters and
ClientHttpConnector's respectively.
The one exception, WebSocket upgrades in spring-webflux, is an internal
framework use case, accommodated via downcast + accessors in the
abstract base classes.
Prior to this commit, asking for a `Void` type using any of the
`ClientResponse#bodyTo*` methods would immediately return an empty
`Publisher` without consuming the response body.
Not doing so can lead to HTTP connection pool inconsistencies and/or
memory leaks, since:
* a connection that still has a response body being written to it cannot
be properly recycled in the connection pool
* incoming `DataBuffer` might not be released
This commit detects when `Void` types are asked as body types and in
those cases does the following:
1. Subscribe to the response body `Publisher` to allow the connection to
be returned to the connection pool
2. `cancel()` the body `Publisher` if the response body is not empty; in
that case, we choose to close the connection vs. consume the whole
response body
Those changes imply that `ClientHttpResponse` and other related
contracts don't need a `close()` method anymore.
Issue: SPR-16018
This commit moves WebFluxUriComponentsBuilder.fromServerRequest to the
ServerRequest interface itself.
Consequently, the WebFluxUriComponentsBuilder is removes itself, as it
contained no other methods.
