In SPR-16892, the `EncoderHttpMessageWriter` has been improved to write
`"Content-Length"` HTTP response headers if the response body is of type
`Mono` (i.e. the actual content length is easily accessible without
buffering a possibly large response body). That change was relying on
the fact that the server side is using a `ChannelSendOperator` to delay
the writing of the body until the first signal is received.
This strategy is not effective on the client side, since no such channel
operator is used for `WebClient`. This commit improves
`EncoderHttpMessageWriter` and delays, for `Mono` HTTP message bodies
only, the writing of the body so that we can write the
`"Content-Length"` header information once we've got the body resolved.
Issue: SPR-16949
(Cherry-picked from 4a26f93a0d)
This commit fix an issue where path variables in a nested parent
RouterFunction were not committed to the request attributes.
Issue: SPR-16868
(cherry picked from commit 8c30b8e)
This commit makes sure the nested path variables are only commited to
the attributes when all predicates match.
Issue: SPR-16692
(cherry picked from commit 51325af)
ServerSentEventHttpMessageReader had logic to split on new lines
and buffer until an empty new line (start of a new event). To account
for random data chunking, it later re-assembled the lines for each
event and split again on new lines. However bufferUntil was still
unreliable a chunk may contain nothing but a newline, which doesn't
necessarily mean an empty newline in the overall SSE stream.
This commit simplifies the above by delegating the splitting of the
stream along newlines to StringDecoder.
Issue: SPR-16744
This breaks the package dependency cycle between web.server/web.method and makes ServerErrorException more generally applicable. Includes deprecation of the plain reason constructor variant, in favor of providing a Method or MethodParameter context (which MatrixVariableMethodArgumentResolver does now).
Consistently return "*/*" if no media types were requested rather than
an empty list. Existing code has to check for both in any case to see
if nothing was requested.
