chore(deps): Bump the python-development group with 3 updates

[dependabot]

Bumps the python-development group with 3 updates: coverage, mypy and tox.

Updates coverage from 7.14.3 to 7.15.2

Release notes

Sourced from coverage's releases.

7.15.2

Version 7.15.2 — 2026-07-15

• Fix: one of the performance improvements in 7.15.1 (pull 2215) dramatically increased memory use during reporting for large projects. Now we use a different approach that is both faster and slimmer than 7.15.0. Fixes issue 2229.

➡️  PyPI page: coverage 7.15.2. :arrow_right:  To install: python3 -m pip install coverage==7.15.2

7.15.1

Version 7.15.1 — 2026-07-12

• Fix: in the HTML report with show_contexts enabled, a context label containing </script> (for example a parametrized pytest node id) could close the inline <script> element in a file page early, injecting markup. Context labels are now fully escaped. Thanks, Rajath Mohare.
• A number of performance improvements thanks to Paul Kehrer, in pull requests 2213, 2214, 2215, 2216, 2218, 2220, and 2221.

➡️  PyPI page: coverage 7.15.1. :arrow_right:  To install: python3 -m pip install coverage==7.15.1

7.15.0

Version 7.15.0 — 2026-07-02

• Since 7.14.0, reporting commands implicitly combine parallel data files. Now those commands have a new option --keep-combined to retain the data files after combining them instead of the default, which is to delete them. Finishes issue 2198.
• Fix: the LCOV report would incorrectly count excluded functions as uncovered, as described in issue 2205. This is now fixed thanks to Martin Kuntz Jacobsen.
• When running your program, coverage now correctly sets yourmodule.__spec__.loader as strongly recommended, avoiding the deprecation warning described in issue 2208. Thanks, A5rocks.
• Fix: with Python 3.10, running with the -I (isolated mode) option didn’t correctly omit the current directory from the module search path, as described in issue 2103. That is now fixed thanks to Ilia Sorokin.

Updates mypy from 2.1.0 to 2.3.0

Mypy Release Notes

Next Release

Packaging changes

• No longer provide mypyc-accelerated wheels for macOS x86_64 [mypyc-wheels #119](mypyc/mypy_mypyc-wheels#119)

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.

Mypyc Free-threading Memory Safety

Free-threaded Python builds that don't have the GIL require additional synchronization primitives or lock-free algorithms to ensure memory safety when there are race conditions (for example, when a thread reads a list item while another thread writes the same list item concurrently). This release greatly improves memory safety of free threading.

List operations are now memory-safe on free threaded Python builds, even in the presence of race conditions. This has some performance cost. For list-heavy workloads, using librt.vecs.vec instead of list is often significantly faster, but note that vec is not (and likely won't be) fully memory safe, and the user is expected to avoid race conditions. The newly introduced librt.threading.Lock helps with this. Using variable-length tuples can also be more efficient than lists, since tuples are immutable and don't require expensive synchronization to ensure memory safety.

Instance attribute access is also (mostly) memory safe now on free-threaded builds in the presence of race conditions. We are planning to fix the remaining unsafe cases in a future release.

Full list of changes:

• Make attribute access memory safe on free-threaded builds (Jukka Lehtosalo, PR 21705)
• Fix unsafe borrowing of instance attributes with free-threading (Jukka Lehtosalo, PR 21688)
• Make list get/set item more memory safe on free-threaded builds (Jukka Lehtosalo, PR 21683)
• Don't borrow list items on free-threaded builds (Jukka Lehtosalo, PR 21679)
• Make multiple assignment from list memory-safe on free-threaded builds (Jukka Lehtosalo, PR 21684)

v4.57.2 (2026-07-21)

Bug fixes - 4.57.2

• Fix package environment creation failures being misreported:

  • discard the partially registered configuration on failure, so the real error surfaces instead of a spurious duplicate configuration definition;
  • report the first creation failure in definition order, not a hash-random one;
  • build the PEP 517 frontend lazily, so tox c and tox l work when pyproject.toml cannot be read. (:issue:3987)

• Fix state corruption in the environment creation machinery:

  • a failed run environment build no longer removes shared package environments other run environments still use;
  • a run environment registers with its package environment once, not twice with triple-counted usage;
  • circular depends reports the cycle as an error instead of a raw traceback;
  • Skip raised by a plugin for a package environment marks the run environment package-skipped instead of crashing with UnboundLocalError. (:issue:3991)

• Fix two packaging regressions:

  • package = editable on a build backend without PEP-660 support now falls back to editable-legacy with a warning instead of crashing, also when the project metadata is static;
  • editable and wheel environments running after an sdist-wheel environment build from the project sources again, instead of a stale temporary copy that made source edits invisible. (:issue:3992)

• An environment serving as both a run environment and a package environment now behaves predictably:

  • one defined through a [testenv:...]-style section and referenced by package_env inherits from pkgenv/env_pkg_base as documented, instead of silently keeping run environment defaults;
  • one listed in env_list while referenced as a package environment is reported as a configuration conflict up front, instead of failing late with cannot run packaging environment or silently disappearing from tox l. (:issue:3993)

• pylock.toml installs now match the lock file:

  • a package locked once per Python range installs only the version matching the environment's interpreter;
  • packages locked to a local directory, VCS repository, or archive install from that source instead of resolving the name against the package index;
  • locked hashes are verified when every entry carries one;
  • changing a pip environment variable such as PIP_INDEX_URL reinstalls, as it already did for deps.
