chore(deps): bump the security group across 1 directory with 3 updates

[dependabot]

Bumps the security group with 3 updates in the / directory: anyio, h2 and hpack.

Updates anyio from 4.13.0 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

Updates h2 from 4.3.0 to 4.4.1

Changelog

Sourced from h2's changelog.

4.4.1 (2026-08-03)

Bugfixes

• Performance improvement: remove consumed frames in-place from data buffer.
• Reject duplicate Host headers in request headers. Thanks to Sunand Mohan for the report.

4.4.0 (2026-07-23)

API Changes (Backward Incompatible)

• Support for Python 3.9 has been removed.
• Support for PyPy 3.9 has been removed.
• Stream.end_stream() now raises NoSuchStreamError or StreamClosedError exceptions, instead of a generic KeyError.
• Duplicate content-length headers with different values now raise ProtocolError. Previously, the first content-length header was accepted and later conflicting values were ignored. Thanks to Harshal Parekh for the report.
• Parse content-length headers according to RFC9110 grammar for numbers (1*DIGIT). Thanks to Arkadiusz Marta for the report.
• backfill from v4.3.0 Convert emitted events into Python dataclass, which introduces new constructors with required arguments. Instantiating these events without arguments, as previously commonly used API pattern, will no longer work.

API Changes (Backward Compatible)

• Support for Python 3.14 has been added.
• H2Connection.receive_data now accepts any byte-like object that implements the buffer protocol, such as bytes, bytearray, and memoryview. Existing bytes callers are unaffected.
• Align CONNECT pseudo-header validation with RFC 9113 s8.3 and RFC 8441 s4. Ordinary CONNECT now requires :method=CONNECT and :authority, and forbids :scheme/:path. Extended CONNECT (e.g., WebSocket) requires :scheme, :path, :authority plus :protocol. (PR #1309)
• Fix incorrect substring matching of secure header in cookie and :method.

Bugfixes

• Fix to allow sending 0 bytes on a stream even if the flow control window is negative.
• Reject non-zero SETTINGS_ENABLE_PUSH values received from servers.

• Support for PyPy 3.9 has been removed.

API Changes (Backward Compatible)

Bugfixes

• Headers marked as sensitive will no longer log their value at DEBUG level. Instead a placeholder value of SENSITIVE_REDACTED is logged.
• Fixed perfect match missed for headers with empty values.
• Restricted variable integer decoding to uint32 to prevent run-away computation. With thanks to Hiroki Nishino_.
