We’ve just uploaded mypy 1.9 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.
Breaking Changes
Because the version of typeshed we use in mypy 1.9 doesn't support 3.7, neither does mypy 1.9. (Jared Hance, PR 16883)
We are planning to enable
local partial types (enabled via the
--local-partial-types flag) later this year by default. This change
was announced years ago, but now it's finally happening. This is a
major backward-incompatible change, so we'll probably include it as
part of the upcoming mypy 2.0 release. This makes daemon and
non-daemon mypy runs have the same behavior by default.
Local partial types can also be enabled in the mypy config file:
local_partial_types = True
We are looking at providing a tool to make it easier to migrate
projects to use --local-partial-types, but it's not yet clear whether
this is practical. The migration usually involves adding some
explicit type annotations to module-level and class-level variables.
Basic Support for Type Parameter Defaults (PEP 696)
This release contains new experimental support for type parameter
defaults (PEP 696). Please try it
out! This feature was contributed by Marc Mueller.
Since this feature will be officially introduced in the next Python
feature release (3.13), you will need to import TypeVar, ParamSpec
or TypeVarTuple from typing_extensions to use defaults for now.
This example adapted from the PEP defines a default for BotT:
from typing import Generic
from typing_extensions import TypeVar
This release is not a usual bug fix release -- it contains features and improvements, being a follow up
to 8.1.0, which has been yanked from PyPI.
:::
Features
#11475: Added the new consider_namespace_packages{.interpreted-text role="confval"} configuration option, defaulting to False.
If set to True, pytest will attempt to identify modules that are part of namespace packages when importing modules.
#11653: Added the new verbosity_test_cases{.interpreted-text role="confval"} configuration option for fine-grained control of test execution verbosity.
See Fine-grained verbosity <pytest.fine_grained_verbosity>{.interpreted-text role="ref"} for more details.
Improvements
#10865: pytest.warns{.interpreted-text role="func"} now validates that warnings.warn{.interpreted-text role="func"} was called with a [str]{.title-ref} or a [Warning]{.title-ref}.
Currently in Python it is possible to use other types, however this causes an exception when warnings.filterwarnings{.interpreted-text role="func"} is used to filter those warnings (see [CPython #103577](python/cpython#103577) for a discussion).
While this can be considered a bug in CPython, we decided to put guards in pytest as the error message produced without this check in place is confusing.
#11311: When using --override-ini for paths in invocations without a configuration file defined, the current working directory is used
as the relative directory.
Previoulsy this would raise an AssertionError{.interpreted-text role="class"}.
#11475: --import-mode=importlib <import-mode-importlib>{.interpreted-text role="ref"} now tries to import modules using the standard import mechanism (but still without changing :pysys.path{.interpreted-text role="data"}), falling back to importing modules directly only if that fails.
This means that installed packages will be imported under their canonical name if possible first, for example app.core.models, instead of having the module name always be derived from their path (for example .env310.lib.site_packages.app.core.models).
#11801: Added the iter_parents() <_pytest.nodes.Node.iter_parents>{.interpreted-text role="func"} helper method on nodes.
It is similar to listchain <_pytest.nodes.Node.listchain>{.interpreted-text role="func"}, but goes from bottom to top, and returns an iterator, not a list.
#11850: Added support for sys.last_exc{.interpreted-text role="data"} for post-mortem debugging on Python>=3.12.
#11962: In case no other suitable candidates for configuration file are found, a pyproject.toml (even without a [tool.pytest.ini_options] table) will be considered as the configuration file and define the rootdir.
#11978: Add --log-file-mode option to the logging plugin, enabling appending to log-files. This option accepts either "w" or "a" and defaults to "w".
Previously, the mode was hard-coded to be "w" which truncates the file before logging.
* Do specifier matching correctly when the specifier contains an epoch number
and has more components than the version (:issue:`683`)
* Support the experimental ``--disable-gil`` builds in packaging.tags
(:issue:`727`)
* BREAKING: Make optional ``metadata.Metadata`` attributes default to ``None`` (:issue:`733`)
* Fix errors when trying to access the ``description_content_type``, ``keywords``,
and ``requires_python`` attributes on ``metadata.Metadata`` when those values
have not been provided (:issue:`733`)
* Fix a bug preventing the use of the built in ``ExceptionGroup`` on versions of
Python that support it (:issue:`725`)
