Deps: Bump the python-packages group with 4 updates

[dependabot]

Bumps the python-packages group with 4 updates: coverage, anyio, librt and mypy.

Updates coverage from 7.15.0 to 7.15.1

Changelog

Sourced from coverage's changelog.

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 <pull 2224_>_.

• A number of performance improvements thanks to Paul Kehrer, in pull requests 2213 <pull 2213_>, 2214 <pull 2214_>, 2215 <pull 2215_>, 2216 <pull 2216_>, 2218 <pull 2218_>, 2220 <pull 2220_>, and 2221 <pull 2221_>_.

Updates anyio from 4.14.1 to 4.14.2

Release notes

Sourced from anyio's releases.

4.14.2

• Changed ByteReceiveStream.receive() implementations to raise a ValueError when max_bytes is not a positive integer (#1191)
• Fixed CapacityLimiter.total_tokens rejecting float("inf") when the limiter was instantiated outside of an event loop. The adapter setter checked for infinity by identity (value is math.inf), so only the exact math.inf singleton was accepted, while every backend setter (using math.isinf()) accepts any positive infinity (#1189; PR by @​greymoth-jp).
• Fixed to_process.run_sync() deadlocking when the worker function writes enough data to sys.stderr to fill the (undrained) pipe buffer. The worker process now redirects sys.stderr to os.devnull as well, matching the documented behavior
• Fixed TLSStream.wrap() matching an internationalized (unicode) host name against the peer certificate using IDNA 2003 (via the standard library) instead of IDNA 2008, which could cause the host name to be matched against the wrong certificate (#1208)
• Fixed anyio.open_process() (and run_process()) ignoring the extra_groups argument, as it mistakenly passed the value of the group argument instead (#1209)
• Fixed CapacityLimiter.acquire_nowait() and CapacityLimiter.acquire_nowait_on_behalf_of() raising trio.WouldBlock instead of anyio.WouldBlock on the trio backend when there are no tokens available (#1218)
• Fixed CapacityLimiter on the asyncio backend over-granting tokens (borrowed_tokens exceeding total_tokens and available_tokens going negative) when a non-blocking acquire was made in the window between a token being released and the notified waiter resuming. The freed token is now reserved for the woken waiter right away, so the non-blocking acquire correctly raises WouldBlock (#1170; PR by @​gaoflow)
• Fixed unnecessary CPU spin when delivering cancellation from CancelScope on asyncio under certain conditions, including improper cancel scope nesting (#1111)

Commits

• c384f99 Bumped up the version
• dbba29d Fixed 100% CPU spin on cancel scope misuse (#1217)

• be24b04 Relaxed timeouts to fix test flakiness
• 8113506 Fix test flakiness caused by slow callback duration logging

Mypy Release Notes

Next Release

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

Closed TypedDicts enable more precise type checking because the type checker knows exactly which keys are present. This is particularly useful when working with TypedDict unions or when you want to ensure that a TypedDict conforms to an exact shape.

The closed keyword also enables safe type narrowing with in checks:

Book = TypedDict('Book', {'book': str}, closed=True)
DVD = TypedDict('DVD', {'dvd': str}, closed=True)
type Inventory = Book | DVD
def print_type(inventory: Inventory) -> None:
if "book" in inventory:
# Type is narrowed to Book here - safe because DVD is closed
print(inventory["book"])
else:
# Type is narrowed to DVD here
print(inventory["dvd"])
</tr></table>
