To slightly improve performance, this commit switches to
StringBuilder.append(char) instead of StringBuilder.append(String)
whenever we append a single character to a StringBuilder.

Prior to this commit, if a PathContainer was created using
Options.MESSAGE_ROUTE, DefaultPathSegment#parameters() returned a
mutable map which would allow the user to modify the contents of the
static, shared EMPTY_PARAMS map in DefaultPathContainer.
This commit prevents corruption of the shared EMPTY_PARAMS map by
ensuring that parameters stored in DefaultPathSegment are always
immutable.
Closes gh-27064
This commit revisits the recently updated `PORT_PATTERN` in
`UriComponentsBuilder`. The fix introduced in gh-26905 fails with
ambiguous URL patterns, especially when the port and path parts of the
pattern are hard to differentiate, for example
"https://localhost:{port}{path}".
This commit reinstates the previous behavior without undoing the actual
fix. The only limitation introduced here is the fact that only a single
pattern variable is allowed for the port pattern part.
Fixes gh-27039
Make sure that we use the parameter name in MultipartBodyBuilder::part
when adding a Part, instead of using the name specified in the
'Content-Disposition' header that might have been in the part's headers.
Closes gh-27007
This commit makes sure that the DefaultPartHttpMessageReader uses a
random temporary directory to store uploaded files, so that two
instances do not collide.
See gh-26931
Recent commit dddcc5e9ad ensured a
trailing "/" in the Origin header has no effect. This commit does the
same for a trailing "/" in configured patterns.
See gh-26892
The pattern was changed in 65797d04f2
to check for characters up until "/", instead of for digits, but now
also checks up until "?" and "#".
Closes gh-26905
Prior to this commit, when Web MVC attempted to resolve a constructor
argument for a data class constructor with @ModelAttribute binding,
ModelAttributeMethodProcessor failed to unwrap the array returned by
WebRequest.getParameter(String).
According to the Javadoc for WebRequest.getParameter(String), "a
single-value parameter will be exposed as an array with a single
element."
This commit fixes this issue by extracting the single value from such
an array and using that as the constructor argument (potentially
converted by the WebDataBinder).
Closes gh-25200
Prior to this commit, `ServerHttpRequest.mutate()` would not reflect
changes made on the "Accept" and "Content-Type" HTTP headers.
This was due to the fact that the instantiation of a new request based
on the mutated values would not use the writable HTTP headers used
during the mutation, but rather a read-only view of the headers backed
by `ReadOnlyHttpHeaders`.
`ReadOnlyHttpHeaders` caches those values for performance reasons, so
getting those from the new request would not reflect the changes made
during the mutation phase.
This commit ensures that the new request uses the mutated headers.
Fixes gh-26615
This commit better aligns how URI variable placeholders are detected
in UriComponentsBuilder#encode (i.e. the pre-encoding of the literal
parts of a URI template) and how they are expanded later on.
The latter relies on a pattern that stops at the first closing '}'
which excludes the possibility for well-formed, nested placeholders
other than variables with regex syntax, e.g. "{year:\d{1,4}}".
UriComponentsBuilder#encode now also stops at the first closing '}' and
further ensures the placeholder is not empty and that it has '{' before
deciding to treat it as a URI variable.
Closes gh-26466
Prior to this commit, WebFlux native headers adapters would delegate the
`httpHeaders.keySet` to underlying implementations that do not honor the
`remove*` methods.
This commit fixes the `Set` implementation backing the
`httpHeaders.keySet` and ensures that headers can be safely removed from
the set.
Fixes gh-26361
This commit only writes the 'charset' parameter in the written headers
if it is non-default (not UTF-8), since RFC7578 states that the only
allowed parameter is 'boundary'.
See gh-25885
