chore(deps): bump anyio from 4.12.1 to 4.14.2

[dependabot]

Bumps anyio from 4.12.1 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)

4.14.1

• Fixed teardown of higher-scoped async fixtures failing on asyncio with RuntimeError: Attempted to exit cancel scope in a different task than it was entered in when an async test raise an outcome exception (e.g., pytest.skip(), pytest.xfail(), or pytest.fail()) (#1179; PR by @​EmmanuelNiyonshuti)
• Fixed CapacityLimiter.total_tokens rejecting a value of 0 when the limiter was instantiated outside of an event loop, contradicting the documented behavior of allowing 0 total tokens (#1183; PR by @​nyxst4ck)

4.14.0

• Added support for Python 3.15

• Added an asynchronous implementation of the itertools module (#998; PR by @​11kkw)

• Added the local_port parameter to connect_tcp() to allow binding to a specific local port before connecting (#1067; PR by @​nullwiz)

• Added support for custom capacity limiters in async path and file I/O functions and classes

• Added the create_task() task group method for easier asyncio migration (returns a TaskHandle) (#1098)

• Changed TaskGroup.start_soon() to return a TaskHandle

• Added an option for TaskGroup.start() to return a TaskHandle (which then contains the start value in the start_value property)

• Added the cancel() convenience method to TaskGroup as a shortcut for cancelling the task group's cancel scope

• Improved the error message when a known backend is not installed to suggest the install command (#1115; PR by @​EmmanuelNiyonshuti)

• Improved anyio.Path to preserve subclass types by returning Self in methods that return path objects (#1130; PR by @​EmmanuelNiyonshuti)

• Changed the parameter type annotation in anyio.Path.write_bytes() to accept any ReadableBuffer, thus allowing it to accept bytearray and memoryview to match pathlib.Path.write_bytes() (#1135; PR by @​SAY-5)

• Changed several type annotations to only accept callables returning coroutine-like objects instead of arbitrary awaitables:

  • TaskGroup.start_soon()
  • TaskGroup.start()
  • anyio.from_thread.run()

  This reverts an earlier change from v3.7.0 which was made in error. (#1153)

• Changed anyio.run to support callables returning arbitrary awaitables at runtime on all backends. Previously, this only worked on asyncio (#1171; PR by @​gschaffner)

• Changed several classes (and their subclasses) to have __slots__ (with __weakref__):

  • anyio.CancelScope

... (truncated)

EntelligenceAI PR Summary

Refreshes the Poetry dependency lockfile and its package metadata without changing application source code.

• Migrated lock format from 2.0 to 2.1
• Added main/development group metadata and conditional environment markers
• Updated AnyIO from 4.12.1 to 4.14.2
• Normalized Python, platform, optional-extra, CUDA/vLLM, and finetuning constraints

Review Scorecard

Dimension	Rating	Basis
Code Quality	●●●●● 5/5 — Excellent	no critical/significant findings — rated Excellent
Blast Radius	Low	dependency reach not measurable here; no high-impact surface touched, 1 file(s) / ~551 line(s) changed (size only — not a blast signal)
Merge Confidence	●●●●● 5/5 — Safe to Merge	code quality 5/5 × Low blast radius

Safe to merge — this is a clean, low-blast-radius dependency lockfile refresh with no application source changes. The migration to lock format 2.1, AnyIO update from 4.12.1 to 4.14.2, and normalized environment markers are internally consistent, with no correctness, security, robustness, or unresolved-review issues identified.

Key Findings:

• The AnyIO version update is confined to dependency metadata and does not introduce application-level logic changes.
• The lockfile metadata and conditional markers explicitly capture Python, platform, optional-extra, CUDA/vLLM, and finetuning constraints rather than relying on implicit resolution behavior.
• No new or pre-existing unresolved review findings indicate runtime, security, data-integrity, or contract problems.

Evaluated against

• criteria: correctness, security & access control, robustness & error handling, concurrency & data integrity, repo conventions / steering docs
• steering docs: none found in repo

Walkthrough

Regenerated the Poetry dependency lockfile using Poetry 2.4.1. The update migrates the lock format to 2.1, adds dependency group and environment marker metadata, refreshes AnyIO, and normalizes conditional dependency constraints without changing application source functionality.

Changes

Files

• poetry.lock

Regenerated with Poetry 2.4.1, updating the lock format from 2.0 to 2.1 and adding metadata for main and development dependency groups. The refresh also records optional, platform-, Python-version-, CUDA/vLLM-, and finetuning-specific markers, updates AnyIO from 4.12.1 to 4.14.2, and normalizes dependency and extra constraints.
