build(deps): bump pyo3-build-config from 0.19.2 to 0.20.0

[dependabot]

Bumps pyo3-build-config from 0.19.2 to 0.20.0.

Release notes

Sourced from pyo3-build-config's releases.

PyO3 0.20.0

This release is the first PyO3 release to be dual-licensed under Apache 2.0 OR MIT licensing (expanding from just Apache 2.0 of previous releases).

Python 3.12 stable is now supported. The minimum supported Rust version has been increased to Rust 1.56.

The __eq__, __ne__, __lt__, __le__, __gt__ and __ge__ magic methods are now usable in #[pymethods] to implement Python operators as an alternative to the __richcmp__ method PyO3 already offered.

#[pyclass(rename_all = "renaming_rule")] has been added to rename all fields of structs exposed to Python (e.g. rename_all = "snake_case") .

PyDict::get_item now returns Result<Option<&PyAny>> instead of just Option<&PyAny>. The previous implementation which ignored Python errors used APIs now considered deprecated by the Python language designers; it is now considered best practice to bubble up any exception raised during dictionary __getitem__. For most users migration for this change will simply require addition of a ? on each use of PyDict::get_item.

Note that Python 3.7 is end of life but PyO3 will continue to support for now as a number of downstream Python packages still have high proportions of downloads on 3.7. A future release is expected to drop Python 3.7 when these numbers reduce.

There have been numerous other smaller improvements, changes and fixes. For full details see the CHANGELOG.

Please consult the migration guide for help upgrading.

[0.20.0] - 2023-10-11

Packaging

• Dual-license PyO3 under either the Apache 2.0 OR the MIT license. This makes the project GPLv2 compatible. #3108
• Update MSRV to Rust 1.56. #3208
• Bump indoc dependency to 2.0 and unindent dependency to 0.2. #3237
• Bump syn dependency to 2.0. #3239
• Drop support for debug builds of Python 3.7. #3387
• Bump chrono optional dependency to require 0.4.25 or newer. #3427
• Support Python 3.12. #3488

Added

• Support __lt__, __le__, __eq__, __ne__, __gt__ and __ge__ in #[pymethods]. #3203
• Add FFI definition Py_GETENV. #3336
• Add as_ptr and into_ptr inherent methods for Py, PyAny, PyRef, and PyRefMut. #3359
• Implement DoubleEndedIterator for PyTupleIterator and PyListIterator. #3366
• Add #[pyclass(rename_all = "...")] option: this allows renaming all getters and setters of a struct, or all variants of an enum. Available renaming rules are: "camelCase", "kebab-case", "lowercase", "PascalCase", "SCREAMING-KEBAB-CASE", "SCREAMING_SNAKE_CASE", "snake_case", "UPPERCASE". #3384
• Add FFI definitions PyObject_GC_IsTracked and PyObject_GC_IsFinalized on Python 3.9 and up (PyPy 3.10 and up). #3403
• Add types for None, Ellipsis, and NotImplemented. #3408
• Add FFI definitions for the Py_mod_multiple_interpreters constant and its possible values. #3494
• Add FFI definitions for PyInterpreterConfig struct, its constants and Py_NewInterpreterFromConfig. #3502

Changed

• Change PySet::discard to return PyResult<bool> (previously returned nothing). #3281
• Optimize implmentation of IntoPy for Rust tuples to Python tuples. #3321
• Change PyDict::get_item to no longer suppress arbitrary exceptions (the return type is now PyResult<Option<&PyAny>> instead of Option<&PyAny>), and deprecate PyDict::get_item_with_error. #3330
• Deprecate FFI definitions which are deprecated in Python 3.12. #3336
• AsPyPointer is now an unsafe trait. #3358
• Accept all os.PathLike values in implementation of FromPyObject for PathBuf. #3374
• Add __builtins__ to globals in py.run() and py.eval() if they're missing. #3378
• Optimize implementation of FromPyObject for BigInt and BigUint. #3379
• PyIterator::from_object and PyByteArray::from now take a single argument of type &PyAny (previously took two arguments Python and AsPyPointer). #3389
• Replace AsPyPointer with AsRef<PyAny> as a bound in the blanket implementation of From<&T> for PyObject. #3391
• Replace blanket impl IntoPy<PyObject> for &T where T: AsPyPointer with implementations of impl IntoPy<PyObject> for &PyAny, &T where T: AsRef<PyAny>, and &Py<T>. #3393
• Preserve std::io::Error kind in implementation of From<std::io::IntoInnerError> for PyErr #3396
• Try to select a relevant ErrorKind in implementation of From<PyErr> for OSError subclass. #3397
• Retrieve the original PyErr in implementation of From<std::io::Error> for PyErr if the std::io::Error has been built using a Python exception (previously would create a new exception wrapping the std::io::Error). #3402
• #[pymodule] will now return the same module object on repeated import by the same Python interpreter, on Python 3.9 and up. #3446
• Truncate leap-seconds and warn when converting chrono types to Python datetime types (datetime cannot represent leap-seconds). #3458
• Err returned from #[pyfunction] will now have a non-None __context__ if called from inside a catch block. #3455
• Deprecate undocumented #[__new__] form of #[new] attribute. #3505

Removed

• Remove all functionality deprecated in PyO3 0.18, including #[args] attribute for #[pymethods]. #3232
• Remove IntoPyPointer trait in favour of into_ptr inherent methods. #3385

... (truncated)
