Release Notes

pyo3/pyo3 (pyo3)

v0.20.0

Compare Source

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

Fixed

• Handle exceptions properly in PySet::discard. #​3281
• The PyTupleIterator type returned by PyTuple::iter is now public and hence can be named by downstream crates. #​3366
• Linking of PyOS_FSPath on PyPy. #​3374
• Fix memory leak in PyTypeBuilder::build. #​3401
• Disable removed FFI definitions _Py_GetAllocatedBlocks, _PyObject_GC_Malloc, and _PyObject_GC_Calloc on Python 3.11 and up. #​3403
• Fix ResourceWarning and crashes related to GC when running with debug builds of CPython. #​3404
• Some-wrapping of Option<T> default arguments will no longer re-wrap Some(T) or expressions evaluating to None. #​3461
• Fix IterNextOutput::Return not returning a value on PyPy. #​3471
• Emit compile errors instead of ignoring macro invocations inside #[pymethods] blocks. #​3491
• Emit error on invalid arguments to #[new], #[classmethod], #[staticmethod], and #[classattr]. #​3484
• Disable PyMarshal_WriteObjectToString from PyMarshal_ReadObjectFromString with the abi3 feature. #​3490
• Fix FFI definitions for _PyFrameEvalFunction on Python 3.11 and up (it now receives a _PyInterpreterFrame opaque struct). #​3500
