In order to be more "reactive", changed StringDecoder's default from
merging all buffers in the stream to a single buffer into splitting the
buffers along newline (\r, \n) characters.
This commit introduces DataBuffer.indexOf(IntPredicate) and
lastIndexOf(IntPredicate), for finding the index of a byte in a
DataBuffer.
It also introduces DataBufferUtils.tokenize, which tokenizes a
DataBuffer into separate tokens, given a delimiter function.
While View and ViewResolver play the same role as in spring-webmvc they
are now abstracted behind the HandlerResultHandler abstraction so that
top-level contracts don't reference them and the DispatcherHandler is
also unaware of their existence.
Furthermore view resolution and response body handling which are now at
the same level of abstraction (each is a HandlerResultHandler) will
also share code for content negotiation, so it makes sense for them to
be side by side.
This commit moves the reactive.view package to reactive.result.view
with the View and ViewResolver contracts (previously in the top-level
reactive package) also moving there.
When a null is returned from an @ResponseBody method, rather than
returning Mono.empty() immediately, convert it to Mono.empty() and
apply the same processing.
Currently that doesn't make a practical difference but it's more
accurate to do it this way. Eventually it may mean the possibility
to turn empty values into something through an extension point
as we do with ResponseBodyAdvice in Spring MVC today.
This commit introduces a pooled data buffer as a subtype of DataBuffer,
as well as various utility methods related to reference counting.
Additionally, Crelease calls have been introduced throughout the
codebase to properly dispose of pooled databuffers.
Rename two classes each adapting to WebHandler to avoid confusing them:
1. HttpWebHandlerAdapter adapts from the low level HttpHandler to any
WebHandler (e.g. DispatcherHandler).
2. SimpleHandlerAdapter adapts the plain WebHandler for use within the
DispatcherHandler.
This commit also fixes an issue in WebHttpHandlerBuilder to ensure that
WebExceptionHandler's are inserted before and not after WebFilter's.
The renaming makes it clear this exception is for use where 400 error
applies within a Spring web application where the error may be
associated with a MethodParameter, a BindingResult, and so on.
There is no need for BadRequestStatusException which can be expressed
with ResponseStatusException(HttpStatus.BAD_REQUEST, "reason").
This commit wraps up the previous commits:
- It uses HttpMessageConverter in the web.reactive.server package instead of Encoder/Decoder.
- It introduces tests for the Resource @ResponseBodies.
This commit introduces a reactive version of the HttpMessageConverter.
During the implementation of zero-copy support, it became apparent that
it was ueful to have a common abstraction between client and server that
operated on HttpMessages rather than DataBuffers.
Two HttpMessageConverter implementations are provided:
- The CodecHttpMessageConverter, based on Encoder/Decoder.
- The ResourceHttpMessageConverter, using zero-copy if available.
This commit introduces support for zero-copy file transfers in the HTTP
response, through the ZeroCopyHttpOutputMessage subinterface of
ReactiveHttpOutputMessage.
This commit introduces two DataBuffer improvements:
- The capability to read a Flux<DataBuffer> from an input stream or
channel.
- The capability to limit a Publisher<DataBuffer> to publish up until a
given maximum byte count.
