Updates mypy from 2.3.0 to 2.3.1

Changelog

Sourced from mypy's changelog.

Mypy 2.3.1

  • Fix mypyc crash on double yielding Iterators (Daniël van Noord, PR 21826)
  • Fix mypyc default_factory for inherited dataclass (Daniël van Noord, PR 21785)
  • Clear mypyc coroutine env on coroutine completion (Piotr Sawicki, PR 21734)
  • Fix crash when unpacking return value from overload (Shantanu, PR 21830)

Acknowledgements

  • Agriya Khetarpal
  • Ethan Sarp
  • Ivan Levkivskyi
  • Jingchen Ye

I'd also like to thank my employer, Dropbox, for supporting mypy development.

Mypy 2.2

We've just uploaded mypy 2.2.0 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.

Support for Closed TypedDicts (PEP 728)

Mypy now supports closed TypedDicts as specified in PEP 728. A closed TypedDict cannot have extra keys beyond those explicitly defined. This allows the type checker to determine that certain operations are safe when they otherwise wouldn't be due to the potential presence of unknown keys.

You can use the closed keyword argument with TypedDict:

HasName = TypedDict("HasName", {"name": str})
HasOnlyName = TypedDict("HasOnlyName", {"name": str}, closed=True)
Movie = TypedDict("Movie", {"name": str, "year": int})
movie: Movie = {"name": "Nimona", "year": 2023}
has_name: HasName = movie  # OK: HasName is open (default)
has_only_name: HasOnlyName = movie  # Error: HasOnlyName is closed and Movie has extra "year" key
</tr></table>

Updates zizmor from 1.28.0 to 1.29.0

Release notes

Sourced from zizmor's releases.

v1.29.0

New Features 🌈🔗

  • zizmor now has experimental support for auditing pre-commit inputs, meaning both pre-commit configuration and hook definitions (#2209)

  • New audit: insecure-url-scheme detects usages of insecure (i.e. plaintext) protocols when making network requests. The initial version of this audit is limited to pre-commit inputs only (#2228)

  • zizmor now supports GitHub's "self-repository" reference syntax for local actions, e.g. uses: $/foo/bar instead of a manual checkout and uses: ./foo/bar (#2248)

Changes ⚠️🔗

Removals 🌅🔗

  • --collect=workflows-only and --collect=actions-only have been fully removed. Use --collect=workflows and --collect=actions for the replacement behavior (#2242)

Bug Fixes 🐛🔗

  • Fixed a bug where zizmor would reject a valid workflow definition for containing a literal jobs..outputs. value for being a non-string (#2220)

  • Fixed a bug where the github-app audit would incorrectly flag some usages as needing a repositories: key, despite requesting organization-level-only permissions (#2227)

  • Fixed a class of bugs where zizmor would discover the user's configuration in unintuitive ways. When auditing from a Git repository, zizmor now uses the repository root to discover configuration consistently (#2234)

  • zizmor now supports GitHub's "self-repository" reference syntax for local actions, e.g. #!yaml uses: $/foo/bar instead of a manual checkout and #!yaml uses: ./foo/bar (#2248)

Changes ⚠️

  • The [unpinned-uses] and [unpinned-images] audits have been separated more cleanly: [unpinned-uses] is now principally responsible for Git-style #!yaml uses: clauses, whereas [unpinned-images] is now responsible for docker://-style #!yaml uses: clauses (in addition to already checking other image references) (#2222)

Removals 🌅

  • --collect=workflows-only and --collect=actions-only have been fully removed. Use --collect=workflows and --collect=actions for the replacement behavior (#2242)

Bug Fixes 🐛

  • Fixed a bug where zizmor would reject a valid workflow definition for containing a literal jobs.<job>.outputs.<name> value for being a non-string (#2220)
