Bumps the development-dependencies group with 2 updates: mypy and ty.

Updates mypy from 1.19.0 to 1.19.1

Changelog

Sourced from mypy's changelog.

Mypy 1.19.1

  • Fix noncommutative joins with bounded TypeVars (Shantanu, PR 20345)
  • Respect output format for cached runs by serializing raw errors in cache metas (Ivan Levkivskyi, PR 20372)
  • Allow types.NoneType in match cases (A5rocks, PR 20383)
  • Fix mypyc generator regression with empty tuple (BobTheBuidler, PR 20371)
  • Fix crash involving Unpack-ed TypeVarTuple (Shantanu, PR 20323)
  • Fix crash on star import of redefinition (Ivan Levkivskyi, PR 20333)
  • Fix crash on typevar with forward ref used in other module (Ivan Levkivskyi, PR 20334)
  • Fail with an explicit error on PyPy (Ivan Levkivskyi, PR 20389)

Mypy 1.18

We’ve just uploaded mypy 1.18.1 to the Python Package Index (PyPI). Mypy is a static type checker for Python. This release includes new features, performance

Bug fixes

  • Improve solving of a type variable with an upper bound when that type variable appears as one element in a union type (#21893)
  • Accurately emulate runtime semantics for kw_only=True dataclasses such that only fields declared in the immediate class body are understood as being keyword-only (#21820)
  • Avoid inferring types for invalid binary expressions in string annotations (#21911)
  • Fix logic used to determine whether two @final instance types are disjoint (#21769)
  • Fix logic used to determine whether two @final type[] types are disjoint (#21770)
  • Fix false-positive diagnostics that could arise when analysing cyclic types (#21910), (#21909)

LSP server

  • Fix outdated version in publish diagnostics after didChange (#21943)
  • Fix workspace symbols to return members too (#21926)
  • Adjust scope completions to use all reachable symbols (#21872)
  • Classify cls as class parameter for semantic highlighting (#21944)
  • Don't show on-hover tooltips for expressions with no inferred type (#21924)
  • Ignore __all__ for document and workspace symbol requests (#21928)
  • Recognize __all__ += submodule.__all__ in auto-import (#21918)
  • Stabilize rename (#21940)

Other changes

  • Support checking files without extensions (#21867)
  • Improve performance and semantics by deferring inference of all parameter and return-type annotations (#21906)
  • Improve resolution of absolute imports in tests (#21817)
  • Infer the implicit type of the cls parameter in @classmethod method bodies (#21685)
  • Support the implicit type of the cls parameter in signatures of @classmethod methods (#21771)
  • Uniformly use "not supported" in diagnostics (#21916)
  • Implement the equivalence relation for TypedDicts (#21784)
  • Ensure that the type of the class object C is always considered assignable to type[C[Unknown]] if C is a generic class (#21883)
  • Improve bad specialization results and error messages (#21840)
  • Support NewTypes of float and complex (#21886)
