Prior to this commit, all `with**Converter` methods in
`HttpMessageConverters` builders would only apply if the
`registerDefaults()` option is on. While the original intent is to allow
overrides for auto-detected defaults, this creates an unnecessary
discrepancy with `addCustomConverter` which is always effective.
Allowing sich registrations when defaults are off should not introduce
invalid states and only reflects the intent of the developer. This
commit now allows such cases.

Now that `RestClient` offers a better alternative, this commit revisits
our integration tests to use `RestClient` instead of `RestTemplate`.
Closes gh-36573
Prior to this commit, the `DefaultRestClient` implementation would
look at the type of the returned value to decide whether the HTTP
response stream needs to be closed before returning.
As of gh-36380, this checks for `InputStream` and `InputStreamResource`
return types, effectively not considering `ResponseEntity<InputStream>`
and variants.
This commit ensures that `ResponseEntity` types are unwrapped before
checking for streaming types.
Fixes gh-36492
Although this commit also changes the visibility of some test methods
to package-private, the remainder of that task will be addressed in
conjunction with gh-36496.
Closes gh-36495
Updates the Content-Disposition header creation logic to use only
ISO-8859-1 characters for the fallback 'filename' parameter instead of
RFC 2047 encoded strings. Non-compatible characters are replaced with '_'.
This does not remove the ability to parse RFC 2047 encoded filenames.
Closes gh-36328

Since the Spring Framework uses American English spelling, this commit
updates Javadoc and the reference manual to ensure consistency in that
regard. However, there are two exceptions to this rule that arise due
to their use within a technical context.
- We use "cancelled/cancelling" instead of "canceled/canceling" in
numerous places (including error messages).
- We use "implementor" instead of "implementer".
Closes gh-36470
Prior to this commit, our implementation of Server Sent Events (SSE),
`SseEmitter` (MVC) and `ServerSentEvent` (WebFlux), would not guard
against invalid characters if the application mistakenly inserts such
characters in the `id` or `event` types.
Both implementations would also behave differently when it comes
to escaping comment multi-line events.
This commit ensures that both implementations handle multi-line comment
events and reject invalid characters in id/event types.
This commit also optimizes `String` concatenation and memory usage
when writing data.
Fixes gh-36440
The RequestHeaderOverrideWrapper did not deduplicate in keySet()
across underlying headers and overrides.
A similar change in size() even if it was working correctly,
to align with keySet and make it more efficient.
Closes gh-36418
Prior to this commit, flush calls on the output stream returned by
`ServletServerHttpResponse#getBody` would be delegated to the Servlet
response output stream.
This can cause performance issues when `HttpMessageConverter` and other
web components write and flush multiple times to the response body.
Here, the Servlet container is in a better position to flush to the
network at the optimal time and buffer the response body until then.
This is particularly true for `HttpMessageConverters` when they flush
many times the output stream, sometimes due to the underlying codec
library. Instead of revisiting the entire message converter contract, we
are here ignoring flush calls to that output stream.
This change does not affect the client side, nor the
`ServletServerHttpResponse#flush` calls.
This commit also introduces a new Spring property
`"spring.http.response.flush.enabled"` that reverts this behavior change
if necessary.
Closes gh-36385
This commit updates the target type detection in
`ResourceHttpMessageConverter` to only support target types that are
relevant: `InputStreamResource` for streaming, and types assignable from
`ByteArrayResource` for non-streaming cases.
Closes gh-36368
This commit fixes the `configureMessageConverters` and
`configureMessageConvertersList` behavior.
`configureMessageConverters` was not executing consumers in their order
of registration (but in the reverse order).
`configureMessageConvertersList` was not executing multiple consumers
and was instead executing the first consumer multiple times.
This commit fixes both issues.
Fixes gh-36332
get method skips containsKey and instead checks if the enumeration
has elements, which should give the same behavior other than for
headers without values.
See gh-36334
The builder for `HttpMessageConverters` allows for auto-detection of
message converters on the classpath and their default registration when
`registerDefaults()` is called. Once called, there is no way to undo
this.
This commit adds a new `disableDefaults()` method to disable the default
registration and take full control over the list of message converters.
Closes gh-36303
Prior to this commit, the `Netty4HeadersAdapter` `MultiValueMapi#remove`
implementation would return an empty list if no value was present. This
is not consistent with other implementations.
This change ensures that `null` is returned for those cases.
Fixes gh-36226
