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, the `setMessageConverters` method would have
private visibility. But `initBodyConvertFunction`, which is `protected`,
relies on the message converters being set in the first place.
While this works with `RestTemplate` because this is done automatically,
the `RestClient` does offer a builder method to configure a
`ResponseErrorHandler` and this makes it impossible to configure
converters in this case.
This commit aligns the method visibility by making it protected.
Closes gh-36434
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
The methods to build a request in RestClientAdapter and WebClientAdapter
are now public to make it easier to create a custom adapter that wraps
the built-in ones and delegates for methods that can be the same.
Closes gh-36374
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
Prior to this commit, a few implementations of the `HttpMessageConverter`
contract were inheriting from abstract classes. Those classes were
performing extra `OutputStream#flush` on the response body even though
this is the responsibility of the super class. Such abstract classes
do flush already, after delegating to the `writeInternal` method.
This commit ensures that we remove such extra calls as they tend to
waste resources for no added benefit.
Closes gh-36383
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
