Bump the dev-dependencies group across 1 directory with 4 updates

[dependabot]

Bumps the dev-dependencies group with 4 updates in the / directory: hypothesis, coverage, mypy and ruff.

Updates hypothesis from 6.152.4 to 6.155.1

Release notes

Sourced from hypothesis's releases.

Hypothesis for Python - version 6.152.9

This release substantially improves our internal distribution for generating integers. This release has the most visible effect on "integers()", but may incidentally improve other strategies which draw integers internally.

Our integers distribution had two problems. First, it had jagged discontinuities at certain values where we switched sampling approaches. Second, it used a different distribution for bounded and unbounded ranges, which resulted in "st.integers()" and "st.integers(-264, 264)" producing very different distributions despite being semantically similar.

We now use a smooth distribution for both "st.integers()" and "st.integers(a, b)", which fixes both of these issues. This should substantially improve our testing power in certain cases.

The only way this release should be user-visible is that it finds more bugs! If this release is user-visible in other ways - for example, because it is slower, or produces a worse distribution in some cases - please open an issue.

Hypothesis for Python - version 6.152.8

This release drops support for end-of-life Django 4.2.

Hypothesis for Python - version 6.152.7

This patch improves our type hints for ".filter()" to work with "typing.TypeGuard". For example:

from typing import TypeGuard

from hypothesis import strategies as st

def is_str(x: object) -> TypeGuard[str]: return isinstance(x, str)

s = st.from_type(object).filter(is_str)

previously: SearchStrategy[object]

now: SearchStrategy[str]

reveal_type(s)

Hypothesis for Python - version 6.152.6

This patch adds a shrinking pass that tries natural text

Updates coverage from 7.13.5 to 7.14.1

Changelog

Sourced from coverage's changelog.

Version 7.14.1 — 2026-05-26

• Fix: the HTML report used typographic niceties to make file paths more readable by adding a small amount of space around slashes. Those spaces interfered with searching the page for file paths of interest. Now the report uses CSS to accomplish the same visual tweak so that searches with slashes work correctly. Closes issue 2170_.

• Add a 3.16 PyPI classifier <hugo-316_>_ since we test on the 3.16 main branch.

Version 7.14.0 — 2026-05-10

• Feature: now when running one of the reporting commands, if there are parallel data files that need combining, they will be implicitly combined before creating the report. There is no option to avoid the combination; let us know if you have a use case that requires it. Thanks, Tim Hatch <pull 2162_>. Closes issue 1781.

• Fix: the output from combine was too verbose, listing each file considered. Now it shows a single line with the counts of files combined, files skipped, and files with errors. The -q flag suppresses this line. The old detailed lines are available with the new --debug=combine option.

• Fix: running a Python file through a symlink now sets the sys.path correctly, matching regular Python behavior. Fixes issue 2157_.

• Fix: Collector.flush_data could fail with "RuntimeError: Set changed size during iteration" when a tracer in another thread added a line to the per-file set that add_lines (or add_arcs) was iterating. The values passed to CoverageData are now snapshotted via dict.copy() and set.copy(), which are atomic under the GIL. Thanks, Alex Vandiver <pull 2165_>_.

• Fix: the soft keyword lazy is now bolded in HTML reports.

• We are no longer testing eventlet support. Eventlet started issuing stern deprecation warnings that break our tests. Our support code is still there.

Mypy Release Notes

Next Release

Mypy 2.1

We’ve just uploaded mypy 2.1.0 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.

librt.vecs: Fast Growable Array Type for Mypyc

The new librt.vecs module provides an efficient growable array type vec that is optimized for mypyc use. It provides fast, packed arrays with integer and floating point value types, which can be several times faster than list, and tens of times faster than array.array in code compiled using mypyc. It also supports nested vec objects and non-value-type items, such as vec[vec[str]].

Refer to the documentation for the details.

Contributed by Jukka Lehtosalo.

librt.random: Fast Pseudo-Random Number Generation

The new librt.random module provides fast pseudo-random number generation that is optimized for code compiled using mypyc. It can be 3x to 10x faster than the stdlib random module in compiled code.

Refer to the documentation for the details.

Contributed by Jukka Lehtosalo (PR 21433).

Mypyc Improvements

• Enable incremental self-compilation (Vaggelis Danias, PR 21369)
• Make compilation order with multiple files consistent (Piotr Sawicki, PR 21419)
• Fix crash on accessing StopAsyncIteration (Piotr Sawicki, PR 21406)
• Fix incremental compilation with separate flag (Vaggelis Danias, PR 21299)

Fixes to Crashes

• Fix crash on partial type with --allow-redefinition and global declaration (Jukka Lehtosalo, PR 21428)
• Fix broken awaitable generator patching (Ivan Levkivskyi, PR 21435)
