Updates setuptools from 84.0.0 to 84.2.0

Changelog

Sourced from setuptools's changelog.

v84.2.0

Features

• Added support for building abi3t extensions and abi3.abi3t wheels on Python 3.15 and newer. See :pep:803 and the Python 3.15 "What's New" entry <https://docs.python.org/3.15/whatsnew/3.15.html#pep-803-abi3t-stable-abi-for-free-threaded-builds>_ for more details. (#5193)
• Updated vendored packaging version to 26.3, which adds support for the abi3t tag from :pep:803. (#5361)

Bugfixes

• Use target sysconfig data for stable-ABI extension filenames. (#5351)

v84.1.0

Features

• setuptools.archive_util now raises the new UnsafeMember exception when an archive member would be extracted outside of the extraction directory, where previously such a member was silently skipped. Aborting makes a malicious or malformed archive visible to the caller instead of yielding a quietly incomplete extraction, and matches the behavior of the standard library's tarfile extraction filters.

Bugfixes

• Wheel.install_as_egg no longer creates namespace package directories outside of the destination egg directory. Entries in a wheel's namespace_packages.txt were split on . and passed straight to os.path.join, so an entry that was absolute, drive-qualified, or UNC discarded the destination and placed an __init__.py at a path chosen by the wheel. Namespace entries are now validated as dotted module names on every platform -- see GHSA-xmj3-9gf7-h52w.

  This code path is reached only by the deprecated setup_requires mechanism when setup() is invoked outside a PEP 517 frontend; the setuptools build backend never reaches it.

• setuptools.archive_util no longer extracts archive members outside of the requested extraction directory. Both the tar and zip formats specify / as

Updates iniconfig from 2.3.0 to 2.3.1

Release notes

Sourced from iniconfig's releases.

Version 2.3.1

Fixes

• Parsing values with many continuation lines is now linear instead of quadratic in time (#78, regarding #77).
• A leading UTF-8 BOM is now stripped when reading INI files. Files saved by Windows editors used to fail with ParseError (#76, thanks @​Pitchfork-and-Torch).

Internal

• iniconfig._parse.ParsedLine.value is now a list of lines. This is private API.

Docs

• The README example now uses IniConfig.parse() (#79, thanks @​MbappeWU).
• Fixed the issue tracker link (#74, thanks @​stefan6419846).

Updates pluggy from 1.6.0 to 1.7.0

Changelog

Sourced from pluggy's changelog.

pluggy 1.7.0 (2026-10-14)

Deprecations and Removals

• [#632](https://github.com/pytest-dev/pluggy/issues/632) <https://github.com/pytest-dev/pluggy/issues/632>_: Hookspec methods defined without self as the first parameter now emit a :class:DeprecationWarning. Add self as the first parameter or use @staticmethod.

Features

• [#170](https://github.com/pytest-dev/pluggy/issues/170) <https://github.com/pytest-dev/pluggy/issues/170>_: Hookspecs can now declare default values for arguments, using the usual def myhook(myarg="default") syntax. This is mainly a backward compatibility feature, to allow a hookspec to add new parameters to an existing hook without breaking existing callers. See :ref:hookspec_arg_default for details.

• [#729](https://github.com/pytest-dev/pluggy/issues/729) <https://github.com/pytest-dev/pluggy/issues/729>_: Tracing now adds detail where str() is ambiguous: empty strings and strings containing whitespace are quoted, and enums and paths show their repr().

  A value spanning several lines is now displayed as a block instead of running into the surrounding trace.

Bug Fixes

• [#629](https://github.com/pytest-dev/pluggy/issues/629) <https://github.com/pytest-dev/pluggy/issues/629>_: Fix hooks failing to register on Python 3.14+ when type annotations use forward references.

• [#315](https://github.com/pytest-dev/pluggy/issues/315) <https://github.com/pytest-dev/pluggy/issues/315>_: Source archives created by git archive (including GitHub's "Source code" downloads) now carry version information, so building pluggy from them no longer fails with a missing version.

• [#442](https://github.com/pytest-dev/pluggy/issues/442) <https://github.com/pytest-dev/pluggy/issues/442>_: With the addition of default values for hookspec arguments, we also changed the precedence of default values for hookimpl arguments. Previously, if a hookimpl function declared a default for an argument, it was always used, even if the hook call passed an explicit value. Now the precedence is changed to: hook call passed value > hookspec default value > hookimpl default value. See :ref:hookimpl_arg_defaults.

• [#701](https://github.com/pytest-dev/pluggy/issues/701) <https://github.com/pytest-dev/pluggy/issues/701>_: Hookimpls and hookspecs are now discovered via :func:inspect.getattr_static, so properties, cached_property and other descriptors are no longer executed while scanning a plugin. Hooks declared through such a descriptor are not supported.

  As a side effect, @hookimpl/@hookspec applied above @classmethod or @staticmethod is now picked up; previously the marker sat on the wrapper where getattr() never saw it. Callables stored directly on a plugin instance -- in its __dict__ or in a __slots__ slot -- keep being called exactly as getattr() returned them, i.e. without an implicit self.

Updates anyio from 4.14.2 to 4.15.1

Release notes

Sourced from anyio's releases.

4.15.1

• Implemented a compatibility fix for supporting direct access of anyio.* submodules from the main package even when those submodules were not directly imported first (#1311 <agronholm/anyio#1311)

4.15.0

• Added support for the newer keyword-only arguments on anyio.Path methods to match the standard library pathlib.Path:

  • follow_symlinks on exists() (Python 3.12+)
  • follow_symlinks on is_dir() (Python 3.13+)
  • follow_symlinks on is_file() (Python 3.13+)
  • follow_symlinks on owner() (Python 3.13+)
  • follow_symlinks on group() (Python 3.13+)
  • newline on read_text() (Python 3.13+)

  (#1286, #1293; PR by @​jaideeppyne)

• Added amap, gather, and as_completed utility functions to simplify common patterns (#1173; PR by @​Graeme22)

• Added --anyio-mode command-line option as an alternative to the anyio_mode ini setting, and fix the pytest plugin's auto mode detection to recognize the mode when set via either mechanism(e.g: pytest_asyncio). (#1242; PR by @​EmmanuelNiyonshuti)

• Added the anyio.Future synchronization primitive which behaves similar to asyncio.Future, allowing tasks to wait for a value (or exception) from another task (#1146; PR by @​Vizonex)

• Added guidance for managing multiple memory object stream producers and consumers with cloned streams (#330; PR by @​nightcityblade)

• Added StapledObjectStream.send_nowait() that delegates to the underlying ObjectSendStream, if it implements it (#1241; PR by @​davidbrochart)

• Added the move_on_at() and fail_at() functions to complement move_on_after() and fail_after()

• Changed the default name for a task spawned with TaskGroup.create_task(func()) to match the default task name for the analogous task spawned with TaskGroup.start_soon(func) or TaskGroup.start(func) in more situations. Previously, the default name of a TaskGroup.create_task task never included the module name. (The default name for a task spawned with TaskGroup.start_soon or TaskGroup.start typically includes the module name.) (#1234; PR by @​gschaffner)

• Changed the anyio and anyio.abc modules to lazily (much like 810) import the necessary submodules. This is done by parsing the AST of the module and building a lookup table from the if TYPE_CHECKING: block. A fallback mode has been provided for installations where the source code is unavailable (e.g. PyInstaller). (#1169)

• Fixed free-threading compatibility issues arising from the fact that on Python 3.14 free-threading builds, newly created threads inherit the current context by default, causing AnyIO to behave erroneously in relation to start_blocking_portal() and anyio.to_thread.run_sync() (#1224; PR by @​EmmanuelNiyonshuti)

• Fixed SpooledTemporaryFile.readinto() and readinto1() reading twice before rollover, so the destination buffer was overwritten by the second read and the file position advanced twice, silently losing data (#1215; PR by @​c-tonneslan)

• Added a reason parameter to fail_after (and the new fail_at) allowing for added exception context when raising TimeoutError (#1227; PR by @​Graeme22)

• Fixed the default TaskHandle.name missing part of the task name for tasks started with TaskGroup.start on Trio (#1231; PR by @​gschaffner)

• Fixed anyio.run leaking, or at least, delaying collection of loop and root_task due to the root task being cached in a RunVar. (#1203; PR by @​tapetersen)

• Fixed anyio.Path.with_stem() silently producing a wrong path (e.g. Path(".txt")) instead of raising ValueError when given an empty stem on a path with a non-empty suffix, unlike pathlib.PurePath.with_stem (#1200; PR by @​Sanjays2402)

• Fixed UNIXSocketStream.aclose() raising asyncio.InvalidStateError when a concurrent receive or send operation had just been cancelled on the asyncio backend (#1267; PR by @​alloutflo)

• Fixed the pytest plugin importing the deprecated _pytest.python.CallSpec2 alias, which triggers PytestRemovedIn10Warning on pytest>=9.2 and crashes pytest at startup when filterwarnings = error is configured (#1271; PR by @​matthewfeickert)

• Fixed an asyncio worker thread race that could raise RuntimeError when the event loop closed between checking its state and scheduling the worker result (#1265; PR by @​hansu650)

• Fixed CapacityLimiter on the asyncio backend over-granting tokens when total_tokens was raised while the limiter was over-subscribed (#1223; PR by @​zelinewang)

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 fastapi from 0.141.1 to 0.153.0

Release notes

Sourced from fastapi's releases.

0.153.0

Unions of form models now apply the same browser form handling as individual models. Empty scalar fields use defaults or produce missing-field errors, empty list items are preserved, omitted boolean fields become False, and unselected files are treated as missing. JSON request bodies are unchanged.

Fixes

• 🐛 Apply browser form handling to unions of Pydantic models. PR #16540 by @​tiangolo.

0.152.0

Validation errors for header parameter models now report the HTTP header name, such as int-val, instead of the Python field name, int_val. Explicit aliases, Header(convert_underscores=False), and Pydantic models with loc_by_alias=False keep their existing behavior.

Fixes

• 🐛 Fix header model validation errors to report HTTP header names. PR #16538 by @​tiangolo.

0.151.0

JSON request bodies now distinguish an explicit null from an omitted value. For individual Body parameters, null is validated as None: nullable types accept it, and non-nullable types reject it even when a default is defined. Defaults and default factories apply only when the value is omitted. This applies both to parameters inside JSON objects and to parameters representing the entire body. Clients that used null to request a default should omit the value instead.

When a JSON object is expected because of Body(embed=True) or multiple body parameters, sending null as the entire body now returns a validation error.

When no file is selected, browsers submit a file part with an empty filename and empty content. FastAPI now treats this as missing: required file fields return a validation error, and fields with defaults or default factories use them. Unselected inputs are ignored in lists of files. Named zero-byte files are still accepted.

Breaking Changes

• 🐛 Treat unselected browser file inputs as missing. PR #16534 by @​tiangolo.

0.149.0

Browsers submit empty text inputs as empty strings (""). FastAPI now treats empty scalar form values as missing in form models, matching individual Form parameters. Required fields return a validation error. Fields with defaults or default factories use them and remain unset in model_dump(exclude_unset=True).

Empty strings inside lists are preserved. Omitted boolean form fields still become False. JSON requests and direct Pydantic validation are unchanged.

Breaking Changes

• 🐛 Treat empty scalar values as missing in form models. PR #16529 by @​tiangolo.

0.148.0

Defaults for omitted Query, Header, Cookie, and Form parameters and model fields are no longer treated as user input. Defaults are not validated unless validate_default=True is enabled. If you rely on validators running for omitted values, enable default validation with Field(validate_default=True) for model fields or, for example, Query(validate_default=True) for individual parameters. Body(validate_default=True) is now honored too.

For parameter models, applying a default no longer marks a field as explicitly set, so model_dump(exclude_unset=True) excludes it. Default factories run once, and validation errors no longer include injected defaults in input.

Omitted boolean form fields still become False and count as explicitly set.

Breaking Changes

• 🐛 Fix default handling for request parameters and models. PR #16527 by @​tiangolo.
