[dependabot]

Bumps guzzlehttp/psr7 from 2.8.0 to 2.12.1.

Release notes

Sourced from guzzlehttp/psr7's releases.

2.12.1

Security

• Reject CR/LF in HTTP method, protocol version, and reason phrase (GHSA-vm85-hxw5-5432)

2.12.0

Deprecated

• Deprecated non-finite float values in Query::build() that guzzlehttp/psr7 3.0 rejects
• Deprecated non-finite float multipart contents that guzzlehttp/psr7 3.0 rejects
• Deprecated non-string scalar bodies in Utils::streamFor(); cast them to a string for 3.0
• Deprecated non-string Uri::withQueryValues() values; cast them to a string for 3.0

2.11.1

Fixed

• Fixed non-finite float values emitting coercion warnings on PHP 8.5

2.11.0

Changed

• Changed Utils::modifyRequest() to reject conflicting URI and Host header changes in the same call
• Changed Header::parse() to split semicolon-separated parameters without repeated regular expression lookaheads
• Changed UriComparator::isCrossOrigin() so only HTTP and HTTPS missing ports receive implicit default ports

Deprecated

• Deprecated invalid PSR-7 arguments that guzzlehttp/psr7 3.0 will require native types for
• Deprecated non-string header values that guzzlehttp/psr7 3.0 will reject
• Deprecated empty header value arrays that guzzlehttp/psr7 3.0 will reject
• Deprecated URI schemes that do not match guzzlehttp/psr7 3.0 syntax requirements
• Deprecated multipart boundary and custom part header metadata that guzzlehttp/psr7 3.0 will reject
• Deprecated reliance on automatic uppercasing of request methods; guzzlehttp/psr7 3.0 preserves method casing
• Deprecated invalid Utils::modifyRequest() change values that guzzlehttp/psr7 3.0 will reject

Fixed

• Fixed Utils::copyToStream() to retry short destination writes instead of dropping the unwritten remainder
• Fixed Header::parse() splitting of semicolon-separated parameters with escaped quotes

2.10.4

Fixed

• Apply UriNormalizer percent-encoding normalizations to URI fragments
• Make LimitStream::getSize() return 0 for slices past the underlying stream end
• Make AppendStream::read() return an empty string when no streams are attached
• Make CachingStream::read() throw on an incomplete cache-target write instead of silently corrupting replays
• Prevent CachingStream::seek() from looping indefinitely when the remote stream makes no progress

2.10.3
