Bumps the uv-dependencies group with 4 updates in the / directory: python-dotenv, click, urllib3 and black.

Updates python-dotenv from 1.2.3 to 1.2.4

Release notes

Sourced from python-dotenv's releases.

v1.2.4

Fixed

• dotenv get no longer exits with code 1 for empty string values (KEY=) by [@​ShamikOfficial] in #700
• An unquoted empty value followed by an inline comment (e.g. KEY= # comment) is now parsed as an empty string instead of the comment text by [@​Noethix55555] in #663
• dotenv run --no-override now expands variable references with the same precedence as load_dotenv(override=False), so a value like ${BASE}/suffix uses the existing BASE from the environment instead of the one from the .env file by [@​ROTl24] in #698

Updates click from 8.4.2 to 8.5.0

Release notes

Sourced from click's releases.

8.5.0

This is the Click 8.5.0 feature release. A feature release may include new features, remove previously deprecated code, add new deprecation, or introduce potentially breaking changes.

We encourage everyone to upgrade. You can read more about our Version Support Policy on our website.

PyPI: https://pypi.org/project/click/8.5.0/ Changes: https://click.palletsprojects.com/page/changes/#version-8-5-0 Milestone https://github.com/pallets/click/milestone/33

• Add built-in shell completion support for PowerShell (Windows PowerShell 5.1+ and pwsh 7+) alongside the existing bash, zsh, and fish completers. Use _FOO_BAR_COMPLETE=powershell_source foo-bar to generate the completion script. #2672 #3637
• Supported versions of Windows enable ANSI terminal styles by default. Colorama is no longer a dependency and is not used. #2986 #3505
• {class}Argument accepts a help parameter, and help output includes a Positional arguments section when argument help is available. #2983 #3473
• confirm() and prompt() strip ANSI color and style codes from the prompt when the output stream does not support them, matching echo(). This stripping was lost in 8.4.0 when #2969 began writing the prompt with input() directly. #3572 #3653
• {class}Path with allow_dash=True no longer triggers a BytesWarning, an error under python -bb, when checking a value against the - convention. #2877 #3642
• Add {func}custom_version_option, a --version option whose output is produced by a callback, covering cases {func}version_option intentionally does not. The feature set of {func}version_option is now frozen; see [discussion #3527](https://github.com/pallets/click/discussions/3527). #3581
• style() and secho() no longer silently drop the 256-color index 0 (black) passed as fg or bg, and now validate color arguments. Invalid colors raise a ValueError instead of a TypeError. #3677
• The automatic help option stores its value under the reserved name _click_default_help instead of help, so a parameter named help no longer breaks parsing. The new name is visible in {meth}Command.to_info_dict output. Parameters that overwrite each other's value trigger a warning: an argument sharing its name with another parameter, or any parameter claiming the reserved name. Options may still share a name to compete for the same value (feature switches). #2819 #3678
• unstyle and the ANSI handling behind help-text wrapping now strip the full CSI escape-sequence grammar. #3681
• Streamline Option flag handling: the flag-kind, type, lazy-default and validation steps in Option.__init__ move into focused helpers, and flag_value and default keep their unset sentinel at construction (resolved lazily on read) so is UNSET reliably tells a user-supplied value from an auto-derived one. Runtime behavior is unchanged, but {meth}Parameter.to_info_dict now resolves default=True on a feature switch to its flag_value, matching what the function receives at call

Updates urllib3 from 2.7.0 to 2.8.0

Release notes

Sourced from urllib3's releases.

2.8.0

🚀 urllib3 is fundraising for HTTP/2 support

urllib3 is raising ~$40,000 USD to release HTTP/2 support and ensure long-term sustainable maintenance of the project. If your company or organization uses Python and would benefit from HTTP/2 support in Requests, pip, cloud SDKs, and thousands of other projects please consider contributing financially to ensure HTTP/2 support is developed sustainably and maintained for the long-haul.

Thank you for your support.

Security

Fixed the following security issues:

• The TLS configuration for HTTPS proxies could be ignored or overridden. (High severity, GHSA-8988-9cw3-xx77)
• HTTPResponse.stream() and read_chunked() could buffer a chunk-size line of unbounded length in memory. (High severity, GHSA-vxq7-64xx-v4gw)
• Chunked Deflate streaming could enter an infinite loop. (Medium severity, GHSA-gh4c-6fx4-qh6g)

[!IMPORTANT] urllib3 2.8.0 fixes HTTPS proxy TLS configuration being ignored or overridden by destination settings. Configurations relying on that behavior may require changes.

Configure proxy CA certificates and client certificates in proxy_ssl_context, and proxy identity checks with proxy_assert_hostname or proxy_assert_fingerprint. Destination client certificates and identity overrides no longer apply to HTTPS forwarding proxy connections.

[!NOTE] CVE IDs had not yet been assigned to these advisories at the time of release due to a backlog at GitHub's CNA.

Deprecations & Removals

• Deprecated using an empty collection as the Retry option allowed_methods to retry any verb. (#5044)

Features

• Added Url.auth_decoded and Url.auth_decoded_joined convenience properties to the result of parse_url(). (#4945)
• Added basic_auth_encoding and proxy_basic_auth_encoding parameters to urllib3.util.make_headers(). (#5092)

Bugfixes

• Fixed response header handling to replace obsolete folded header lines (obs-fold) with spaces in accordance with RFC 9112, preventing raw CRLF sequences from appearing in header values such as Set-Cookie. (#1362)

• Fixed usage of proxy_ssl_context with ProxyManager when use_forwarding_for_https=True. Passing ssl_context instead of proxy_ssl_context for HTTPS proxies in this configuration now emits a FutureWarning and will raise an error in v3.0. (#2577)

• Changed behavior of the default ConnectionPool.pool initialization. LifoQueue is now resolved from the queue module after the ConnectionPool is instantiated instead of using the default cached QueueCls class property. This is done because sometimes the queue.LifoQueue is monkey-patched late in the program, such as by gevent. (#3289)

• Raised UnrewindableBodyError instead of ValueError when retrying a request whose body had tell() but not seek(). (#3779)

• Decoded percent-encoded SOCKS proxy credentials before authenticating with the proxy server. (#3785)

• Fixed HTTPResponse.drain_conn() to discard unread response data in 64 KiB chunks (same as the default amt when doing HTTPResponse.stream(...)). (#5019)

• Fixed is_ipaddress() to detect non-standard IPv4 forms accepted by socket.connect, such as hex (0x7f000001), octal (0177.0.0.1), and decimal integers (2130706433), ensuring SSL certificate verification uses the correct mode for these addresses. (#5029)

• Fixed HTTPConnectionPool.urlopen raising a misleading FullPoolError instead of ValueError when called with an invalid timeout argument on a pool created with block=True. (#5059)

• Fixed port-zero handling to preserve explicit :0 values instead of substituting the default ports 80 or 443 in URL parsing, pool selection, proxy configuration, connection_from_url(), and HTTP/2 request authority. (#5071, #5101)

• Fixed a bug where PoolManager passed the assert_hostname and assert_fingerprint parameters to HTTP connection pools. (#5077)

• Fixed HTTPConnectionPool.urlopen() and HTTP proxy forwarding to strip URL fragments from absolute request targets before sending requests. (#5079)

• Added safeguards to the proxy tunneling code to prevent potential security issues when handling invalid characters in the proxy host and HTTP headers. This change affects users of Python 3.10, Python 3.11, and Python 3.12 when the standard library does not contain the fix; those on newer Python versions should upgrade to 3.13.14+ or 3.14.5+ to get the same security fixes. (#5091)

• Fixed HTTPSConnection.connect() overriding ProxyConfig.ssl_context's certificate policy and proxy identity checks with the target connection's TLS settings when forwarding through an HTTPS proxy.

  HTTPSConnection no longer applies target SNI, assertions, or client credentials to forwarding proxy handshakes and continues to use its ssl_context as a fallback when an HTTPS proxy forwards an HTTP target. (#5093)

• Fixed URL parsing to more strictly enforce RFC 3986 host syntax, rejecting invalid host input such as raw spaces and control characters, malformed percent-encodings, and percent-encoded control characters in HTTP(S) hosts and IPv6 zone identifiers, including proxy CONNECT tunnel targets. Host normalization now also follows RFC 3986 normalization rules for percent-encoded octets by decoding percent-encoded unreserved characters and uppercasing the hexadecimal digits of retained percent-encoded octets. (#5095)
