Mon Nov 17 02:10:39 UTC 2025 - Steve Kowalik <steven.kowalik@suse.com>
- Update to 25.3.0:
* Potentially breaking: Abstract sets are now structured into frozensets.
* Python 3.14 is now supported and part of the test matrix.
* Fix unstructuring NewTypes with the {class}BaseConverter.
* Make some Hypothesis tests more robust.
* {func}cattrs.strategies.include_subclasses now works with generic parent
classes and the tagged union strategy.
* Potentially breaking: Sequences are now structured into tuples.
* Add a use_alias parameter to cattrs.Converter.
* The union passthrough strategy now by default accepts ints for unions
that contain floats but not ints, when configured to be able to handle
both ints and floats. This more closely matches the current typing
behavior.
* Fix unstructuring of generic classes with stringified annotations.
* The default disambiguation hook factory is now only enabled for
converters with unstructure_strat=AS_DICT (the default).
* Switch to uv and just in lieu of PDM, tox and Make.
* Fixed AttributeError: no attribute '__parameters__' while structuring
attrs classes that inherit from parametrized generic aliases from
collections.abc.
* Potentially breaking: The converters raise StructureHandlerNotFoundError
more eagerly (on hook creation, instead of on hook use). This helps
surfacing problems with missing hooks sooner.
* typing.Self is now supported in attrs classes, dataclasses, TypedDicts
and the dict NamedTuple factories. See typing.Self for details.
* PEP 695 type aliases can now be used with
BaseConverter.register_structure_hook and
BaseConverter.register_unstructure_hook. Previously, they required the
use of BaseConverter.register_structure_hook_func.
* Some defaultdicts are now supported by default, and
cattrs.cols.is_defaultdict and cattrs.cols.defaultdict_structure_factory
are exposed through cattrs.cols.
* Generic PEP 695 type aliases are now supported.
* The tagged union strategy now also supports type aliases of unions.
* Converter.copy and BaseConverter.copy are correctly annotated as
returning Self.
* Many preconf converters (bson, stdlib JSON, cbor2, msgpack, msgspec,
orjson, ujson) skip unstructuring int and str enums, leaving them to the
underlying libraries to handle with greater efficiency.
* The msgspec JSON preconf converter now handles dataclasses with private
attributes more efficiently.
* Preconf converters now handle dictionaries with literal keys properly.
* Structuring TypedDicts from invalid inputs now properly raises a
ClassValidationError.
* cattrs.strategies.include_subclasses now properly works with generic
parent classes.
* Python 3.13 is now supported.
* Python 3.8 is no longer supported, as it is end-of-life.
- Dropped patches, no longer required:
* fix-test-no-nans.patch
* support-python-3.13.patch
-------------------------------------------------------------------
Wed May 7 11:21:09 UTC 2025 - John Paul Adrian Glaubitz <adrian.glaubitz@suse.com>
- Update to 24.1.3
* Fix structuring of keyword-only dataclass fields when not
using detailed validation. (#637)
- Refresh support-python-3.13.patch
-------------------------------------------------------------------
Fri Nov 15 14:19:05 UTC 2024 - Yunus Acar <yunus.acar@suse.com>
- add fix-test-no-nans.patch to get the tests to work with the
latest attrs

-------------------------------------------------------------------
Mon Oct 28 22:38:02 UTC 2024 - Dirk Müller <dmueller@suse.com>
- update to 24.1.2:
* Fix {meth}`BaseConverter.register_structure_hook` and
{meth}`BaseConverter.register_unstructure_hook` type hints.
* Fix {meth}`BaseConverter.register_structure_hook_factory` and
{meth}`BaseConverter.register_unstructure_hook_factory` type
hints.
* **Potentially breaking**: Unstructuring hooks for
`typing.Any` are consistent now: values are unstructured
using their runtime type.
* Introduce {meth}`BaseConverter.get_structure_hook` and
{meth}`BaseConverter.get_unstructure_hook` methods.
* Enhance the {func}`cattrs.cols.is_mapping` predicate function
to also cover virtual subclasses of `abc.Mapping`.
* Introduce the _msgspec_ {mod}`preconf converter
<cattrs.preconf.msgspec>`.
* Add support for PEP 695 type aliases.
* Add support for PEP 696 `TypeVar`s with defaults.
* Add support for named tuples with type metadata
(`typing.NamedTuple`).
* Add support for optionally un/unstructuring named tuples
using dictionaries.
* PEP 695 generics are now tested.
* Imports are now sorted using Ruff.
* Tests are run with the pytest-xdist plugin by default.
* Rework the introductory parts of the documentation,
introducing the Basics section.
* The documentation has been significantly reworked.
* The docs now use the Inter font.
* Make type annotations for `include_subclasses` and
`tagged_union` strategies more lenient.

Thu Dec 14 09:18:25 UTC 2023 - Petr Gajdos <pgajdos@suse.com>
- update to 23.2.3:
* Fix a regression when unstructuring dictionary values typed
as `Any`.
* (#453 #462)
* Fix a regression when unstructuring unspecialized generic
classes.
* (#465 #466)
* Optimize function source code caching.
* (#445 #464)
* Generate unique files only in case of linecache enabled.
* (#445 #441)
* ## 23.2.2 (2023-11-21)
* Fix a regression when unstructuring `Any | None`.
* (#453 #454)
* ## 23.2.1 (2023-11-18)
* Fix unnecessary `typing_extensions` import on Python 3.11.
* (#446 #447)
* ## 23.2.0 (2023-11-17)
* **Potentially breaking**: skip _attrs_ fields marked as
`init=False` by default. This change is potentially breaking
for unstructuring.
* See here for instructions on how to restore the old behavior.
* (#40 #395)
* **Potentially breaking**:
{py:func}`cattrs.gen.make_dict_structure_fn` and
{py:func}`cattrs.gen.typeddicts.make_dict_structure_fn` will
use the values for the `detailed_validation` and
`forbid_extra_keys` parameters from the given converter by
default now.
* If you're using these functions directly, the old behavior
can be restored by passing in the desired values directly.
* (#410 #411)
* **Potentially breaking**: The default union structuring
strategy will also use fields annotated as `typing.Literal`
to help guide structuring.
* See here for instructions on how to restore the old behavior.
* (#391)
* Python 3.12 is now supported. Python 3.7 is no longer
supported; use older releases there.
* (#424)
* Implement the `union passthrough` strategy, enabling much
richer union handling for preconfigured converters. Learn
more here.
* Introduce the `use_class_methods` strategy. Learn more here.
* (#405)
* The `omit` parameter of {py:func}`cattrs.override` is now of
type `bool | None` (from `bool`).
* `None` is the new default and means to apply default _cattrs_
handling to the attribute, which is to omit the attribute if
it's marked as `init=False`, and keep it otherwise.
* Converters can now be initialized with custom fallback hook
factories for un/structuring.
* (#331 #441)
* Add support for `date` to preconfigured converters.
* (#420)
* Add support for `datetime.date`s to the PyYAML preconfigured
converter.
* (#393)
* Fix {py:func}`format_exception() <cattrs.v.format_exception>`
parameter working for recursive calls to
{py:func}`transform_error <cattrs.transform_error>`.
* (#389)
* _attrs_ aliases are now supported, although aliased fields
still map to their attribute name instead of their alias by
default when un/structuring.
* (#322 #391)
* Fix TypedDicts with periods in their field names.
* (#376 #377)
* Optimize and improve unstructuring of `Optional` (unions of
one type and `None`).
* (#380 #381)
* Fix {py:func}`format_exception <cattrs.v.format_exception>`
and {py:func}`transform_error <cattrs.transform_error>` type
annotations.
* Improve the implementation of `cattrs._compat.is_typeddict`.
The implementation is now simpler, and relies on fewer
private implementation details from `typing` and
typing_extensions.
* (#384)
* Improve handling of TypedDicts with forward references.
* Speed up generated _attrs_ and TypedDict structuring
functions by changing their signature slightly.
* (#388)
* Fix copying of converters with function hooks.
* (#398 #399)
* Broaden {py:func}`loads'
<cattrs.preconf.orjson.OrjsonConverter.loads>` type
definition for the preconf orjson converter.
* (#400)
* {py:class}`AttributeValidationNote
<cattrs.AttributeValidationNote>` and
{py:class}`IterableValidationNote
<cattrs.IterableValidationNote>` are now picklable.
* (#408)
* Fix structuring `Final` lists.
* (#412)
* Fix certain cases of structuring `Annotated` types.
* (#418)
* Fix the tagged union strategy to work with
`forbid_extra_keys`.
* (#402 #443)
* Use PDM instead of Poetry.
* _cattrs_ is now linted with Ruff.
* Remove some unused lines in the unstructuring code.
* (#416)
* Fix handling classes inheriting from non-generic protocols.
* (#374 #436)
* The documentation Makefile now supports the `htmlview` and
`htmllive` targets. (#442)
* _cattrs_ is now published using PyPI Trusted Publishers, and
`main` branch commits are automatically deployed to Test
PyPI.
* ## 23.1.2 (2023-06-02)
* Improve `typing_extensions` version bound. (#372)
* ## 23.1.1 (2023-05-30)
* Add `typing_extensions` as a direct dependency on 3.10.
* (#369 #370)
* ## 23.1.0 (2023-05-30)
* Introduce the `tagged_union` strategy.
* (#318 #317)
* Introduce the `cattrs.transform_error` helper function for
formatting validation exceptions. (258 342)

* `pathlib.Path` is now supported by default.
* (#81)
* Add `cbor2` serialization library to the `cattrs.preconf`
package.
* Add optional dependencies for `cattrs.preconf` third-party
libraries. (#337)
* All preconf converters now allow overriding the default
`unstruct_collection_overrides` in `make_converter`.
* (#350 #353)
* Subclasses structuring and unstructuring is now supported via
a custom `include_subclasses` strategy.
* (#312)
* Add support for `typing_extensions.Annotated` when the python
version is less than `3.9`. (#366)
* Add unstructuring and structuring support for the standard
library `deque`.
* (#355)
