This commit avoids invoking StringBuilder.append(Object) in favor
of explicit method calls to append(String) and append(char) in
ContentDisposition.escapeQuotationsInFilename(String).
Closes gh-25056
Prior to this commit, patterns like `"/path/**/other"` would be treated
as `"/path/*/other"` (single wildcard, i.e. matching zero to many chars
within a path segment). This will not match multiple segments, as
expected by `AntPathMatcher` users or by `PathPatternParser` users when
in patterns like `"/resource/**"`.
This commit now rejects patterns like `"/path/**/other"` as invalid.
This behavior was previously warned against since gh-24958.
Closes gh-24952
When mutating a ServerHttpRequest or ClientResponse, the respective
builders no longer access cookies automatically which causes them to
be parsed and does so only if necessary. Likewise re-applying the
read-only HttpHeaders wrapper is avoided.
See gh-24680
Native server request headers have been wrapped rather than copied
since 5.1. This commit applies the same change to the client side
where, to make matters worse, headers were copied repeatedly on every
access, see also previous commit ca897b95.
For Netty and Jetty the wrappers are the same as on the server side
but duplicated in order to remain package private.
See gh-24680
This commit introduces a test suite for ClientHttpConnector
implementations, as well as fixes that resolve issues identified by
these tests.
Closes gh-24941
As of gh-24952, `PathPatternParser` will strictly reject patterns with
`"**"` in the middle of them. `"**"` is only allowed at the end of the
pattern for matching multiple path segments until the end of the path.
Currently, if `"**"` is used in the middle of a pattern it will be
considered as a single `"*"` instead. Rejecting such cases should
clarify the situation.
This commit prepares for that upcoming change and:
* logs a warning message if such a case is used by an application
* expands the MVC and WebFlux documentation about URI matching in
general
Closes gh-24958
