CompositeHttpHandler is public and called ContextPathCompositeHandler.
Also an overhaul of the Javadoc on HttpHandler, WebHttpHandlerAdapter,
and ContextPathCompositeHandler.
Extract CompositeHttpHandler to a package private class and add direct
support via `HttpHandler.of(...)`. This removes the need for the
`HttpHandlerAdapterSupport` class.
Currently the BOM versions are:
* reactor-core 3.0.6.BUILD-SNAPSHOT
* reactor-netty 0.6.2.BUILD-SNAPSHOT
This commit fixes as well a few deprecations in reactor-core.
The SSE reader is ordered ahead of StringDecoder because with
response.decodeToFlux(String.class) we actually want the SSE reader
to get involved first based on the content-type.
At the same time with response.decodeToMono(String.class) there is
nothing the SSE reader can do while the StringDecoder could read the
entore content as one String, as long as the server does terminate
the stream which can happen in a testing scenario.
This commit updates ServerSentEventHttpMessageReader#readMono in
to support String.class by delegating to StringDecoder. Since
reading to a Mono is an explicit choice there is not much possibility
for interfering with decoding to Flux.

This commit simplifies the use of DataBufferFactory in the SSE reader
which is used only to wrap a byte[] as a DataBuffer. There is no actual
benefit to use anything other than a DefaultDataBufferFactory.
From spring-webflux to spring-web test sources since it is perfectly
usable for testing Spring MVC annotation method support.
Potentially to be promoted further up for use in any module that has
annotation method support. It has spring-core dependencies only
`PathPatternParser` is now thread-safe and creates a new internal parser
for each `parse` call, since this operation is cheap.
This commit removes the `ThreadLocal` based instances of
`PathPatternParser` in `ParsingPathMatcher` which are not required
anymore.
Issue: SPR-15246
With this change the original PathPatternParser is renamed
InternalPathPatternParser and a new PathPatternParser class is added.
This new PathPatternParser class is a very simple thread-safe wrapper for
the InternalPathPatternParser. It achieves this by creating a new
InternalPathPatternParser for each new parse request. This follows the
model used for SpEL parsing.
Prior to this commit, the `ShallowEtagHeaderFilter` could participate in
the response and set its ETag/Content-Length headers, even for HEAD
requests. Since the response body is empty, the filter implementation
would set a `"Content-Length: 0"`.
The RFC states that responses to HEAD requests should exhibit identical
response headers to GET (with the possible exception of payload related
headers such as Content-Length.
With this commit, `ShallowEtagHeaderFilter` now ignores HEAD requests
since the proper values may be set already for payload related headers
by the handler. The filter has no way to generate a proper ETag value
nor calculate the content length without the actual body.
Issue: SPR-15261
The first fix for issue 15264 covered the case of using a single
variable (the case mentioned in the bug report). However, when
more than one variable is used a different PathElement is built.
This RegexPathElement needs a similar change that checks the
path includes data to bind.
Issue: SPR-15264
This commit checks that a "Content-Length" request header isn't already
present before adding one in `Netty4ClientHttpRequestFactory`.
`HttpMessageConverter` implementations can write that request header so
the Netty request factory should only write that value when the header
is missing.
If that header is not written (and since we're not dealing with
the HTTP exchange in a chunked-based fashion), the HTTP client might not
send the request body at all.
Issue: SPR-15241
This commit ensures that the `PathPatternParser` and the associated
cache map are used in a threadsafe fashion, since the PathMatcher
instance can be used for concurrent requests.
Issue: SPR-15246
This commit reduces the exposition of `PathPattern` instances throughout
the `HandlerMapping` API and removes some methods from its public API.
Issue: SPR-14544
Since the introduction of `PathPatternRegistry`, the various path match
configuration flags are no longer needed in several places and that
configuration can live in the registry itself.
Issue: SPR-14544
This commit adds the new `PathPatternRegistry`, which holds a
sorted set of `PathPattern`s and allows for searching/adding patterns
This registry is being used in `HandlerMapping` implementations and
separates path pattern parsing/matching logic from the rest. Directly
using `PathPattern` instances should improve the performance of those
`HandlerMapping` implementations, since the parsing and generation of
pattern variants (trailing slash, suffix patterns, etc) is done only
once.
