[dependabot]

Bumps the python-minor-patch group with 4 updates: pydantic, pytest, ruff and mypy.

Updates pydantic from 2.14.1 to 2.14.2

Release notes

Sourced from pydantic's releases.

v2.14.2 2026-10-29

v2.14.2 (2026-10-29)

This release addresses 2 security issues, GHSA-qpmf-fgh3-ff25 and GHSA-3r8g-cqwr-jr29.

Packaging

• Bump PyO3 to 0.30.1, jiter to 0.18.0, use PyFrozenDict by @​Viicos in #14003
• Bump speedate to v0.18.0 by @​Viicos in #14007
• Publish pydantic-core wheels for PyPy 8.0 (pp80 ABI) by @​Viicos in #14083

Performance

• Avoid Python tuple allocation during model fields validation by @​Viicos in #13955
• Lazily call repr of values during nested union serialization by @​Viicos in #14082
• Skip decorator field checks when no field decorators exist by @​alexmojaki in #14111
• Avoid heap allocation for small JSON model field buffers by @​alexmojaki in #14113

Fixes

• Make JSON validation by iteration consistent with Python approach by @​davidhewitt in #13275.

  JSON validation now handles field lookup and extra data the same way as Python validation. In particular, keys that only match an unused alias or field name are now treated as extra data, instead of being silently dropped:

  from pydantic import BaseModel, ConfigDict
  from pydantic.alias_generators import to_camel
  class Page(BaseModel):
  model_config = ConfigDict(extra='forbid', alias_generator=to_camel)
  page_size: int = 10
  
  Page.model_validate_json('{"page_size": 50}')
  Before: Page(page_size=10)
  After: ValidationError (extra_forbidden)

  See the pull request for the full list of behavior changes. This change addresses GHSA-qpmf-fgh3-ff25.

• Ignore extra data matching a field name in TypedDict and dataclasses with extra=allow by @​Viicos in #14090. Addresses GHSA-3r8g-cqwr-jr29.

• Fix unpickling of generic classes defined in separate module by @​Viicos in #13994

• Support explicit by_alias overriding validate_by_alias in validation JSON schemas by @​Viicos in #13997

• Fix mypy plugin crash on deferred empty model by @​ilevkivskyi in #14027

• Fix infinite recursion when validating an invalid default with PydanticUseDefault by @​Viicos in #14028

• Implement recursion guard for validate_strings() by @​Viicos in #14029

Updates pytest from 9.1.1 to 9.2.0

Release notes

Sourced from pytest's releases.

9.2.0

pytest 9.2.0 (2026-10-27)

Removals and backward incompatible breaking changes

• #14716: -c now raises a usage error for a path that does not exist, is a directory, or is in a format pytest has no loader for. Such paths were previously either ignored or reported as an unhandled FileNotFoundError.

• #8593: The indirect, ids and scope arguments of Metafunc.parametrize() <pytest.Metafunc.parametrize> -- and therefore of @pytest.mark.parametrize <pytest.mark.parametrize ref> -- are now keyword-only.

  Passing them positionally was a common source of confusing errors, e.g. parametrize("arg1", "arg2", [(1, 2)]) made the argvalues land in indirect and failed with indirect fixture '(1, 2)' doesn't exist; such mistakes now fail with an understandable TypeError. The type annotations have always declared these arguments as keyword-only.

• #993: Plugin import failures at startup are now reported and classified instead of escaping as a raw traceback with the accidental exit code 1:

  • a plugin that cannot be found -- via -p, pytest_plugins or PYTEST_PLUGINS -- exits with pytest.ExitCode USAGE_ERROR (4), like a conftest.py that fails to import;
  • a plugin that is found but raises while importing -- including a broken pytest11 entry point or a missing plugin dependency -- exits with pytest.ExitCode INTERNAL_ERROR (3), with the traceback preserved.

  pytest.main now returns these codes instead of raising ImportError. Also fixed an IndexError from pytest's own internals when the plugin raised an exception with no arguments.

Deprecations (removal in next major release)

• #14742: The private _pytest.python.CallSpec2 name has been renamed to CallSpec. The old CallSpec2 alias remains available for now and will be removed in pytest 10 or 11.

• #14755: Schedule yield_fixture decorator for removal in pytest 10 or 11.

• #14774: Similarly to the deprecation of class-scoped fixtures defined as instance methods in pytest 9.1, all higher-scoped fixtures (module, package, and session) defined as instance methods are now deprecated.

  They suffer from the same issue the original deprecation only fixed for class-scoped fixtures, see 10819 and 14011.

• #14808: Passing a non-string value to a string-typed ini option now emits a pytest.PytestRemovedIn10Warning. This affects [tool.pytest.ini_options] in pyproject.toml. In pytest 10 this will raise a TypeError, matching the behavior of the corresponding TOML config path.

• #7323: Passing bytes to TerminalReporter.write_line() is now deprecated, pass a str instead.

New features

• #14743: Full diff: now contains a legend explaining the + & - symbols in diff output.
• #2781: When strict_markers is enabled, marker names used in -m expressions are now validated against registered markers.
• #6881: Added the parametrize_long_str_id_strategy configuration option to control how long str/bytes parameter values are handled in auto-generated test IDs. Explicit IDs set via ids=[...] or pytest.param(..., id=...) are not affected. Available strategies: short (default, values over 100 chars fall back to argname+index), sha256 (SHA-256 hex digest), legacy (keep full value), and disallow (error requesting explicit IDs).

Improvements in existing functionality

• #10745: A RecursionError whose recursion origin cannot be located now shows only the first and last 10 stack frames, matching what pytest already did when locating the origin failed outright. Previously the full traceback -- often around a thousand near-identical frames -- was rendered, which was both slow and unreadable. Pass --full-trace to see every frame.

Mypy 2.3

We've just uploaded mypy 2.3.0 to the Python Package Index (PyPI). Mypy is a static type checker for Python. This release includes new features, performance improvements and bug fixes. You can install it as follows:

python3 -m pip install -U mypy

You can read the full documentation for this release on Read the Docs.

The Upcoming Switch to the New Native Parser

We are planning to enable the new native parser (--native-parser) by default soon. We recommend that you test the native parser in your projects and report any issues in the mypy issue tracker.
