Updates pydantic from 2.14.1 to 2.14.2

Release notes

Sourced from pydantic's releases.

v2.14.2 2026-10-29

v2.14.2 (2026-10-29)

This release addresses 2 security issues, GHSA-qpmf-fgh3-ff25 and GHSA-3r8g-cqwr-jr29.

Packaging

• Bump PyO3 to 0.30.1, jiter to 0.18.0, use PyFrozenDict by @​Viicos in #14003
• Bump speedate to v0.18.0 by @​Viicos in #14007
• Publish pydantic-core wheels for PyPy 8.0 (pp80 ABI) by @​Viicos in #14083

Performance

• Avoid Python tuple allocation during model fields validation by @​Viicos in #13955
• Lazily call repr of values during nested union serialization by @​Viicos in #14082
• Skip decorator field checks when no field decorators exist by @​alexmojaki in #14111
• Avoid heap allocation for small JSON model field buffers by @​alexmojaki in #14113

Fixes

• Make JSON validation by iteration consistent with Python approach by @​davidhewitt in #13275.

  JSON validation now handles field lookup and extra data the same way as Python validation. In particular, keys that only match an unused alias or field name are now treated as extra data, instead of being silently dropped:

  from pydantic import BaseModel, ConfigDict
  from pydantic.alias_generators import to_camel
  class Page(BaseModel):
  model_config = ConfigDict(extra='forbid', alias_generator=to_camel)
  page_size: int = 10
  
  Page.model_validate_json('{"page_size": 50}')
  Before: Page(page_size=10)
  After: ValidationError (extra_forbidden)

  See the pull request for the full list of behavior changes. This change addresses GHSA-qpmf-fgh3-ff25.

• Ignore extra data matching a field name in TypedDict and dataclasses with extra=allow by @​Viicos in #14090. Addresses GHSA-3r8g-cqwr-jr29.

• Fix unpickling of generic classes defined in separate module by @​Viicos in #13994

• Support explicit by_alias overriding validate_by_alias in validation JSON schemas by @​Viicos in #13997

• Fix mypy plugin crash on deferred empty model by @​ilevkivskyi in #14027

• Fix infinite recursion when validating an invalid default with PydanticUseDefault by @​Viicos in #14028

• Implement recursion guard for validate_strings() by @​Viicos in #14029

Updates xlsxwriter from 3.3.0 to 3.3.1

Changelog

Sourced from xlsxwriter's changelog.

Release 3.3.1 - October 28 2026

• Fixed performance issue where positioning objects such as images and comments on a worksheet with a custom default row height.

  :issue:1210.

• Fixed a (different) performance issue where positioning a large number of objects such as comments on a worksheet with custom row heights or column widths.

  :issue:1217.

• Fixed off by one error in the worksheet :func:set_first_sheet() method.

  :issue:1187.

• Fixed issue where :func:autofit() hid a column that had a user defined width narrower than the autofit width.

  :issue:1219.

• Fixed issue where :func:add_table() didn't detect a duplicate header name when a user defined header matched a default ColumnN header.

  :issue:1215.

• Fixed issue where the strings_to_formulas Workbook option didn't prevent :func:write() from converting strings like {=SUM(A1:B1*A2:B2)} to array formulas.

  :issue:1212.

• Fixed :func:set_column() rounding a half-pixel width to the nearest even pixel, which made some widths one pixel narrower than in 3.2.9.

  :issue:1221.

• Fixed unescaped double quotes, and incorrect string lengths for characters such as emojis, in text type conditional formats.

  :issue:1206.

• Fixed issue where "future" functions such as ISFORMULA() weren't prefixed with _xlfn. in :func:conditional_format() and :func:data_validation() formulas. See :ref:formula_future.

  :issue:1171.

Updates pytest from 9.1.1 to 9.2.0

Release notes

Sourced from pytest's releases.

9.2.0

pytest 9.2.0 (2026-10-27)

Removals and backward incompatible breaking changes

• #14716: -c now raises a usage error for a path that does not exist, is a directory, or is in a format pytest has no loader for. Such paths were previously either ignored or reported as an unhandled FileNotFoundError.

• #8593: The indirect, ids and scope arguments of Metafunc.parametrize() <pytest.Metafunc.parametrize> -- and therefore of @pytest.mark.parametrize <pytest.mark.parametrize ref> -- are now keyword-only.

  Passing them positionally was a common source of confusing errors, e.g. parametrize("arg1", "arg2", [(1, 2)]) made the argvalues land in indirect and failed with indirect fixture '(1, 2)' doesn't exist; such mistakes now fail with an understandable TypeError. The type annotations have always declared these arguments as keyword-only.

• #993: Plugin import failures at startup are now reported and classified instead of escaping as a raw traceback with the accidental exit code 1:

  • a plugin that cannot be found -- via -p, pytest_plugins or PYTEST_PLUGINS -- exits with pytest.ExitCode USAGE_ERROR (4), like a conftest.py that fails to import;
  • a plugin that is found but raises while importing -- including a broken pytest11 entry point or a missing plugin dependency -- exits with pytest.ExitCode INTERNAL_ERROR (3), with the traceback preserved.

  pytest.main now returns these codes instead of raising ImportError. Also fixed an IndexError from pytest's own internals when the plugin raised an exception with no arguments.

Deprecations (removal in next major release)

• #14742: The private _pytest.python.CallSpec2 name has been renamed to CallSpec. The old CallSpec2 alias remains available for now and will be removed in pytest 10 or 11.

• #14755: Schedule yield_fixture decorator for removal in pytest 10 or 11.

• #14774: Similarly to the deprecation of class-scoped fixtures defined as instance methods in pytest 9.1, all higher-scoped fixtures (module, package, and session) defined as instance methods are now deprecated.

  They suffer from the same issue the original deprecation only fixed for class-scoped fixtures, see 10819 and 14011.

• #14808: Passing a non-string value to a string-typed ini option now emits a pytest.PytestRemovedIn10Warning. This affects [tool.pytest.ini_options] in pyproject.toml. In pytest 10 this will raise a TypeError, matching the behavior of the corresponding TOML config path.

• #7323: Passing bytes to TerminalReporter.write_line() is now deprecated, pass a str instead.

New features

• #14743: Full diff: now contains a legend explaining the + & - symbols in diff output.
• #2781: When strict_markers is enabled, marker names used in -m expressions are now validated against registered markers.
• #6881: Added the parametrize_long_str_id_strategy configuration option to control how long str/bytes parameter values are handled in auto-generated test IDs. Explicit IDs set via ids=[...] or pytest.param(..., id=...) are not affected. Available strategies: short (default, values over 100 chars fall back to argname+index), sha256 (SHA-256 hex digest), legacy (keep full value), and disallow (error requesting explicit IDs).

Improvements in existing functionality

• #10745: A RecursionError whose recursion origin cannot be located now shows only the first and last 10 stack frames, matching what pytest already did when locating the origin failed outright. Previously the full traceback -- often around a thousand near-identical frames -- was rendered, which was both slow and unreadable. Pass --full-trace to see every frame.

Updates anyio from 4.15.1 to 4.16.0

Release notes

Sourced from anyio's releases.

4.16.0

New features

• Added BlockingPortal.call_async() for asynchronously calling into an event loop with optional abandonment on cancellation (#1342; PR by @​davidbrochart)
• Added SOCK_SEQPACKET support to connect_unix() and create_unix_listener() (#1349; PR by @​theunkn0wn1)

Other changes

• Changed UDP sockets on the asyncio backend to make send() wait until the datagram has been passed to the operating system (#1294; PR by @​graingert)

Bug fixes

• Fixed documentation implying that use_uvloop=True falls back to the standard event loop when uvloop (winloop on Windows) is not installed, and showed how to skip the corresponding pytest backend variant when the dependency is missing (#645; PR by @​GruffElixir)
• Fixed get_current_task() on the asyncio backend raising an opaque TypeError: cannot create weak reference to 'NoneType' object instead of a clear error when called from a callback scheduled via loop.call_soon_threadsafe() (e.g. from within from_thread.run_sync()), where asyncio.current_task() is legitimately None (#773; PR by @​AmirF194)
• Fixed CancelScope on the asyncio backend swallowing a native Task.cancel() that was delivered in the same event loop iteration as the scope's own cancellation (such as a move_on_after() deadline expiring), which left the host task with a pending cancellation request that never raised CancelledError (#1214)
• Fixed UDP socket closing hanging if a datagram send was still in flight (#1237; PR by @​graingert)
• Fixed concurrent aclose_forcefully() calls on asyncio socket streams returning before the underlying socket was closed (#1273; PR by @​graingert)
• Fixed aclose() on sockets not checkpointing, and thus failing to raise a cancellation exception when called inside a cancelled scope (affected UNIX socket streams and UNIX datagram sockets on asyncio, and all sockets on Trio) (#1288; PR by @​graingert)
• Fixed aclose() on asyncio TCP socket listeners not checkpointing, and leaking the listening socket if cancelled while another task was waiting in accept() (#1289; PR by @​graingert)
• Fixed accept() on asyncio UNIX socket listeners hanging forever, and leaving the listening socket registered with the event loop, when the listener was closed by another task (#1289; PR by @​graingert)
• Fixed send() on asyncio TCP and UDP sockets returning normally, despite the data being discarded, when the socket was closed by another task (or, for TCP, the connection was lost) while send() was waiting for the operating system to accept the data (#1289; PR by @​graingert)
• Fixed SocketStream.send() on the asyncio backend handing its data to a paused transport after a previous send() was cancelled (#1299; PR by @​graingert)
• Fixed sleep() treating a negative delay (including -inf) inconsistently across backends (asyncio returned immediately; Trio raised ValueError) by raising ValueError on all backends (#1306; PR by @​BetterAndBetterII)
• Fixed create_tcp_listener() occasionally failing with a message like Could not create 2 listeners with a consistent port when an ephemeral port is requested and IPv6 is enabled and the dual-stack path is not available or a specific local host name was given (#1313)
• Fixed AsyncFile not shielding against cancellation while closing (#1314)
• Fixed TemporaryDirectory.cleanup() reacting to cancellation prematurely when the host task was already cancelled, causing the actual cleanup operation to be skipped (#1316; PR by @​Yasser-Ameur)
• Fixed a NaN deadline being accepted on asyncio while Trio raised ValueError, which silently disabled the timeout (fail_after(math.nan) returned instead of raising TimeoutError); CancelScope now rejects it on both backends (#1317; PR by @​dylanpulver)
• Fixed FileReadStream and FileWriteStream leaving files open when cancelled during context manager exit, including unflushed writes (#1318; PR by @​Kuang-xianxin)
• Fixed Condition.notify() and Condition.notify_all() failing when the underlying lock was acquired directly rather than through the condition (#1319; PR by @​GruffElixir)
• Fixed importing AnyIO with loaders that do not provide __file__, such as PyOxidizer, raising TypeError instead of falling back to eager imports (#1322; PR by @​skulitom)
• Fixed text receive streams silently discarding incomplete characters at end-of-file instead of applying the configured decoding error handler (#1339; PR by @​Aurelucien)
• Fixed Semaphore(fast_acquire=True) losing its fast-acquire behavior when instantiated outside a running event loop (#1348; PR by @​feiiiiii5)
• Fixed BlockingPortalProvider permanently failing with an AttributeError on every subsequent use if the first attempt to start its blocking portal failed (#1350; PR by @​Yasser-Ameur)
• Fixed create_udp_socket() silently ignoring the local_port argument when local_host was omitted, making the socket bind to a random ephemeral port instead of the requested one (#1351; PR by @​januththedev)
• Fixed worker threads on the asyncio backend never returning to the idle pool (and thus never being reused or pruned) when a to_thread.run_sync() call was cancelled after it had been queued for the worker but before the worker thread had picked it up (#1352; PR by @​Zac-HD)
• Fixed pytest plugin running Hypothesis async tests only on the first parametrized backend instead of each backend (#1353; PR by @​DYNOSuprovo)
• Fixed TypeError when subclassing an existing TypedAttributeSet subclass, and this subclass contains type annotations (#1358; PR by @​pasmud)
• Fixed Lock.locked() (and Condition.locked()) raising NoEventLoopError when the lock was created outside a running event loop (#1362; PR by @​00200200)
• Fixed connect_tcp() leaking a connected socket when an enclosing cancel scope was cancelled before the connection attempt task group exited (#1364; PR by @​charan-rathore)
• Fixed create_connected_udp_socket() silently ignoring local_port when local_host was not given: the local address was left unset, so the OS picked an ephemeral port instead of the requested one (#1365; PR by @​feiiiiii5)
• Fixed BlockingPortalProvider not passing the exception raised in its with block on to the start_blocking_portal() context manager it wraps (#1366; PR by @​feiiiiii5)
• Fixed anyio.itertools.islice() not consuming the first start items when stop <= start (#1372; PR by @​Rodrigo-Palma)
• Fixed BufferedByteReceiveStream.receive_exactly() and receive_until() returning buffered data after explicit closure instead of raising ClosedResourceError (#1378; PR by @​kokotatan)
• Fixed a TLS stream sending records the peer could no longer decrypt after a cancelled send() lost an already-encrypted record; the stream now raises BrokenResourceError on further use instead (#1385; PR by @​Kayvan-Zahiri)
• Fixed close() on memory object streams not waking up tasks blocked in send() or receive() on the same stream (#1391)
• Fixed anyio.itertools.product() acquiring and consuming unused input iterables when repeat=0 (#1394; PR by @​sricharanreddycheruku)
• Fixed SpooledTemporaryFile rolling over to disk on writes when max_size is zero (the default) (#1397; PR by @​fhgffy)
• Fixed Trio UDP sockets remaining open when initialization failed or was cancelled (#1400; PR by @​adenzhou1350)

Updates filelock from 4.2.4 to 4.2.6

Release notes

Sourced from filelock's releases.

4.2.6

Bug fixes

• Fix a race in SoftFileLock, MarkerSoftFileLock and SoftFileLease when three or more contenders reclaim a dead marker. The race could strand a live holder's marker under a break name, leaving the lock unusable or admitting a second holder. Contenders now recheck the marker before exchanging names and unwind nested exchanges in order. If the filesystem refuses a return exchange, the contender leaves its marker at the lock path for later recovery (#899) by @​dxbjavid and @​gaborbernat.

PyPI release

Full Changelog

4.2.5

Bug fixes

• acquire and acquire raise TypeError for a blocking that is not a bool, as the constructor and the blocking setter already do. A truthy value such as the string "false" used to count as True, so a call meant as a single attempt waited for the instance's timeout, and without a limit at the default -1 (#870) by @​simpleqt and @​gaborbernat.
• A SoftFileLock acquisition whose first read of its new marker's identity failed reads it again before rolling back. On Windows the rollback could otherwise not recognize the marker it had created, and the empty marker it left blocked the path for every later acquisition, since no contender breaks an empty marker (#869) by @​simpleqt and @​gaborbernat.
• A fork() child of a process holding a SoftFileLease starts from an unheld claim. It used to inherit the parent's token, last compromise and heartbeat, so token and compromise reported a claim the child never held while is_locked reported it unheld (#868) by @​dxbjavid and @​gaborbernat.
• A nested acquire of a held FileLock or SoftFileLock no longer creates the lock file's parent directory. After a rename of that directory during the hold, the nested acquire recreated the old name, and when a file had taken the name it raised FileExistsError and left the hold's recursion count incremented (#878) by @​0x5t4l1n and @​gaborbernat.
• Fix ReadWriteLock failing every acquire with "link directory ... was replaced while opening" in a group-writable directory whose inherited ACL, such as an NFSv4 one on ZFS, opens the link directory to the group. The lock now closes the empty link directory to its owner, and where the filesystem refuses that, such as ZFS with aclmode=restricted, it names the directory to make writable by its owner only (#898) by @​gaborbernat.
• Fix SoftFileLock, MarkerSoftFileLock and SoftFileLease raising OverflowError out of acquire(), or never reclaiming a dead holder's lock, when a stranded restore claim beside the lock names a process number outside 1..2**31-1 or spells it in non-ASCII digits. Such a claim is now ignored, as no filelock writes one (#871) by @​dxbjavid and @​gaborbernat.
• Fix soft locks on Windows keeping the marker of a holder that has exited while another process still holds a handle to it, such as a parent's subprocess.Popen after wait() or multiprocessing.Process after join(). Acquiring such a lock with the default timeout=-1 waited forever (#874) by @​nk-batman21.
• Fix the read-only reopen of a lock file this account cannot write resolving a relative path against the working directory of the moment. A chdir between the refused O_RDWR open and the reopen made the acquisition wait on a file that is not there, or probe one in another directory. The reopen now uses the path the acquisition pinned (#889) by @​dxbjavid and @​gaborbernat.
• Handle EMLINK, the error FreeBSD reports when a no-follow open refuses a symlink, in a soft reader/writer lock's protocol tree, so heartbeat reports lost ownership there rather than a transient refresh error (#866) by @​pacocartones and @​gaborbernat.
• Resolving ReadWriteLock or AsyncReadWriteLock raises the ImportError when a module other than Python's sqlite3 is missing, as in a frozen application that left out a filelock submodule. The names are None only without SQLite (#880) by @​pintu544 and @​gaborbernat.

Documentation

• The lock-probing recipe in the how-to guide probes with blocking=False instead of a tiny timeout (#873) by @​tongwentao and @​gaborbernat.

Packaging

• Releases now run on the shared tox-dev/github-workflows pipeline, with a locked release toolchain and generated GitHub Release notes (#885) by @​gaborbernat.

Fixed

• :class:~filelock.ReadWriteLock, :class:~filelock.SoftReadWriteLock and their async wrappers now raise :class:TypeError for a blocking that is not a :class:bool, in the constructor and on acquire, as :class:~filelock.FileLock already does. Before, blocking=0 waited out the full timeout on a contended :class:~filelock.ReadWriteLock while blocking=False failed at once, and a truthy value such as "false" turned a single attempt into a blocking wait (:pr:908) by :user:abhishekcpp007 and :user:gaborbernat.
