[#505](https://github.com/PyO3/pyo3/pull/512) - `PyBytes` can now be indexed just like `Vec` - Implement `IntoPy` for `PyRef` and `PyRefMut`. ### Changed - Implementing the Using the `gc` parameter for `pyclass` (e.g. `#[pyclass(gc)]`) without implementing the `class::PyGCProtocol` trait is now a compile-time error. Failing to implement this trait could lead to segfaults. [#532](https://github.com/PyO3/pyo3/pull/532) - `PyByteArray::data` has been replaced with `PyDataArray::to_vec` because returning a `&[u8]` is unsound. (See [this comment](https://github.com/PyO3/pyo3/issues/373#issuecomment-512332696) for a great write-up for why that was unsound) - Replace `mashup` with `paste`. - `GILPool` gained a `Python` marker to prevent it from being misused to release Python objects without the GIL held. ### Removed - `IntoPyObject` was replaced with `IntoPy` - `#[pyclass(subclass)]` is hidden a `unsound-subclass` feature because it's causing segmentation faults. ### Fixed - More readable error message for generics in pyclass [#503](https://github.com/PyO3/pyo3/pull/503) ## [0.7.0] - 2019-05-26 ### Added - PyPy support by omerbenamram in [#393](https://github.com/PyO3/pyo3/pull/393) - Have `PyModule` generate an index of its members (`__all__` list). - Allow `slf: PyRef` for pyclass(#419) - Allow to use lifetime specifiers in `pymethods` - Add `marshal` module. [#460](https://github.com/PyO3/pyo3/pull/460) ### Changed - `Python::run` returns `PyResult<()>` instead of `PyResult<&PyAny>`. - Methods decorated with `#[getter]` and `#[setter]` can now omit wrapping the result type in `PyResult` if they don't raise exceptions. ### Fixed - `type_object::PyTypeObject` has been marked unsafe because breaking the contract `type_object::PyTypeObject::init_type` can lead to UB. - Fixed automatic derive of `PySequenceProtocol` implementation in [#423](https://github.com/PyO3/pyo3/pull/423). - Capitalization & better wording to README.md. - Docstrings of properties is now properly set using the doc of the `#[getter]` method. - Fixed issues with `pymethods` crashing on doc comments containing double quotes. - `PySet::new` and `PyFrozenSet::new` now return `PyResult<&Py[Frozen]Set>`; exceptions are raised if the items are not hashable. - Fixed building using `venv` on Windows. - `PyTuple::new` now returns `&PyTuple` instead of `Py`. - Fixed several issues with argument parsing; notable, the `*args` and `**kwargs` tuple/dict now doesn't contain arguments that are otherwise assigned to parameters. ## [0.6.0] - 2019-03-28 ### Regressions - Currently, [#341](https://github.com/PyO3/pyo3/issues/341) causes `cargo test` to fail with weird linking errors when the `extension-module` feature is activated. For now you can work around this by making the `extension-module` feature optional and running the tests with `cargo test --no-default-features`: ```toml [dependencies.pyo3] version = "0.6.0" [features] extension-module = ["pyo3/extension-module"] default = ["extension-module"] ``` ### Added - Added a `wrap_pymodule!` macro similar to the existing `wrap_pyfunction!` macro. Only available on python 3 - Added support for cross compiling (e.g. to arm v7) by mtp401 in [#327](https://github.com/PyO3/pyo3/pull/327). See the "Cross Compiling" section in the "Building and Distribution" chapter of the guide for more details. - The `PyRef` and `PyRefMut` types, which allow to differentiate between an instance of a rust struct on the rust heap and an instance that is embedded inside a python object. By kngwyu in [#335](https://github.com/PyO3/pyo3/pull/335) - Added `FromPy` and `IntoPy` which are equivalent to `From` and `Into` except that they require a gil token. - Added `ManagedPyRef`, which should eventually replace `ToBorrowedObject`. ### Changed - Renamed `PyObjectRef` to `PyAny` in #388 - Renamed `add_function` to `add_wrapped` as it now also supports modules. - Renamed `#[pymodinit]` to `#[pymodule]` - `py.init(|| value)` becomes `Py::new(value)` - `py.init_ref(|| value)` becomes `PyRef::new(value)` - `py.init_mut(|| value)` becomes `PyRefMut::new(value)`. - `PyRawObject::init` is now infallible, e.g. it returns `()` instead of `PyResult<()>`. - Renamed `py_exception!` to `create_exception!` and refactored the error macros. - Renamed `wrap_function!` to `wrap_pyfunction!` - Renamed `#[prop(get, set)]` to `#[pyo3(get, set)]` - `#[pyfunction]` now supports the same arguments as `#[pyfn()]` - Some macros now emit proper spanned errors instead of panics. - Migrated to the 2018 edition - `crate::types::exceptions` moved to `crate::exceptions` - Replace `IntoPyTuple` with `IntoPy>`. - `IntoPyPointer` and `ToPyPointer` moved into the crate root. - `class::CompareOp` moved into `class::basic::CompareOp` - PyTypeObject is now a direct subtrait PyTypeCreate, removing the old cyclical implementation in [#350](https://github.com/PyO3/pyo3/pull/350) - Add `PyList::{sort, reverse}` by chr1sj0nes in [#357](https://github.com/PyO3/pyo3/pull/357) and [#358](https://github.com/PyO3/pyo3/pull/358) - Renamed the `typeob` module to `type_object` ### Removed - `PyToken` was removed due to unsoundness (See [#94](https://github.com/PyO3/pyo3/issues/94)). - Removed the unnecessary type parameter from `PyObjectAlloc` - `NoArgs`. Just use an empty tuple - `PyObjectWithGIL`. `PyNativeType` is sufficient now that PyToken is removed. ### Fixed - A soudness hole where every instances of a `#[pyclass]` struct was considered to be part of a python object, even though you can create instances that are not part of the python heap. This was fixed through `PyRef` and `PyRefMut`. - Fix kwargs support in [#328](https://github.com/PyO3/pyo3/pull/328). - Add full support for `__dict__` in [#403](https://github.com/PyO3/pyo3/pull/403). ## [0.5.3] - 2019-01-04 ### Fixed - Fix memory leak in ArrayList by kngwyu [#316](https://github.com/PyO3/pyo3/pull/316) ## [0.5.2] - 2018-11-25 ### Fixed - Fix undeterministic segfaults when creating many objects by kngwyu in [#281](https://github.com/PyO3/pyo3/pull/281) ## [0.5.1] - 2018-11-24 Yanked ## [0.5.0] - 2018-11-11 ### Added - `#[pyclass]` objects can now be returned from rust functions - `PyComplex` by kngwyu in [#226](https://github.com/PyO3/pyo3/pull/226) - `PyDict::from_sequence()`, equivalent to `dict([(key, val), ...])` - Bindings for the `datetime` standard library types: `PyDate`, `PyTime`, `PyDateTime`, `PyTzInfo`, `PyDelta` with associated `ffi` types, by pganssle [#200](https://github.com/PyO3/pyo3/pull/200). - `PyString`, `PyUnicode`, and `PyBytes` now have an `as_bytes()` method that returns `&[u8]`. - `PyObjectProtocol::get_type_ptr()` by ijl in [#242](https://github.com/PyO3/pyo3/pull/242) ### Changed - Removes the types from the root module and the prelude. They now live in `pyo3::types` instead. - All exceptions are consturcted with `py_err` instead of `new`, as they return `PyErr` and not `Self`. - `as_mut` and friends take and `&mut self` instead of `&self` - `ObjectProtocol::call` now takes an `Option<&PyDict>` for the kwargs instead of an `IntoPyDictPointer`. - `IntoPyDictPointer` was replace by `IntoPyDict` which doesn't convert `PyDict` itself anymore and returns a `PyDict` instead of `*mut PyObject`. - `PyTuple::new` now takes an `IntoIterator` instead of a slice - Updated to syn 0.15 - Splitted `PyTypeObject` into `PyTypeObject` without the create method and `PyTypeCreate` with requires `PyObjectAlloc + PyTypeInfo + Sized`. - Ran `cargo edition --fix` which prefixed path with `crate::` for rust 2018 - Renamed `async` to `pyasync` as async will be a keyword in the 2018 edition. - Starting to use `NonNull<*mut PyObject>` for Py and PyObject by ijl [#260](https://github.com/PyO3/pyo3/pull/260) ### Removed - Removed most entries from the prelude. The new prelude is small and clear. - Slowly removing specialization uses - `PyString`, `PyUnicode`, and `PyBytes` no longer have a `data()` method (replaced by `as_bytes()`) and `PyStringData` has been removed. - The pyobject_extract macro ### Fixed - Added an explanation that the GIL can temporarily be released even while holding a GILGuard. - Lots of clippy errors - Fix segfault on calling an unknown method on a PyObject - Work around a [bug](https://github.com/rust-lang/rust/issues/55380) in the rust compiler by kngwyu [#252](https://github.com/PyO3/pyo3/pull/252) - Fixed a segfault with subclassing pyo3 create classes and using `__class__` by kngwyu [#263](https://github.com/PyO3/pyo3/pull/263) ## [0.4.1] - 2018-08-20 ### Changed - PyTryFrom's error is always to `PyDowncastError` ### Fixed - Fixed compilation on nightly since `use_extern_macros` was stabilized ### Removed - The pyobject_downcast macro ## [0.4.0] - 2018-07-30 ### Changed - Merged both examples into one - Rustfmt all the things :heavy_check_mark: - Switched to [Keep a Changelog](http://keepachangelog.com/en/1.0.0/) ### Removed - Conversions from tuples to PyDict due to [rust-lang/rust#52050](https://github.com/rust-lang/rust/issues/52050) ## [0.3.2] - 2018-07-22 ### Changed - Replaced `concat_idents` with mashup ## [0.3.1] - 2018-07-18 ### Fixed - Fixed scoping bug in pyobject_native_type that would break rust-numpy ## [0.3.0] - 2018-07-18 ### Added - A few internal macros became part of the public api ([#155](https://github.com/PyO3/pyo3/pull/155), [#186](https://github.com/PyO3/pyo3/pull/186)) - Always clone in getters. This allows using the get-annotation on all Clone-Types ### Changed - Upgraded to syn 0.14 which means much better error messages :tada: - 128 bit integer support by [kngwyu](https://github.com/kngwyu) ([#137](https://github.com/PyO3/pyo3/pull/173)) - `proc_macro` has been stabilized on nightly ([rust-lang/rust#52081](https://github.com/rust-lang/rust/pull/52081)). This means that we can remove the `proc_macro` feature, but now we need the `use_extern_macros` from the 2018 edition instead. - All proc macro are now prefixed with `py` and live in the prelude. This means you can use `#[pyclass]`, `#[pymethods]`, `#[pyproto]`, `#[pyfunction]` and `#[pymodinit]` directly, at least after a `use pyo3::prelude::*`. They were also moved into a module called `proc_macro`. You shouldn't use `#[pyo3::proc_macro::pyclass]` or other longer paths in attributes because `proc_macro_path_invoc` isn't going to be stabilized soon. - Renamed the `base` option in the `pyclass` macro to `extends`. - `#[pymodinit]` uses the function name as module name, unless the name is overrriden with `#[pymodinit(name)]` - The guide is now properly versioned. ## [0.2.7] - 2018-05-18 ### Fixed - Fix nightly breakage with proc_macro_path ## [0.2.6] - 2018-04-03 ### Fixed - Fix compatibility with TryFrom trait #137 ## [0.2.5] - 2018-02-21 ### Added - CPython 3.7 support ### Fixed - Embedded CPython 3.7b1 crashes on initialization #110 - Generated extension functions are weakly typed #108 - call_method*() crashes when the method does not exist #113 - Allow importing exceptions from nested modules #116 ## [0.2.4] - 2018-01-19 ### Added - Allow to get mutable ref from PyObject #106 - Drop `RefFromPyObject` trait - Add Python::register_any() method ### Fixed - Fix impl `FromPyObject` for `Py` - Mark method that work with raw pointers as unsafe #95 ## [0.2.3] - 11-27-2017 ### Changed - Rustup to 1.23.0-nightly 2017-11-07 ### Fixed - Proper `c_char` usage #93 ### Removed - Remove use of now unneeded 'AsciiExt' trait ## [0.2.2] - 09-26-2017 ### Changed - Rustup to 1.22.0-nightly 2017-09-30 ## [0.2.1] - 09-26-2017 ### Fixed - Fix rustc const_fn nightly breakage ## [0.2.0] - 08-12-2017 ### Added - Added inheritance support #15 - Added weakref support #56 - Added subclass support #64 - Added `self.__dict__` supoort #68 - Added `pyo3::prelude` module #70 - Better `Iterator` support for PyTuple, PyList, PyDict #75 - Introduce IntoPyDictPointer similar to IntoPyTuple #69 ### Changed - Allow to add gc support without implementing PyGCProtocol #57 - Refactor `PyErr` implementation.
