# Changelog All notable changes to this project will be documented in this file. The format is based on [Keep a Changelog](http://keepachangelog.com/en/1.0.0/) and this project adheres to [Semantic Versioning](http://semver.org/spec/v2.0.0.html). ## [Unreleased] ### 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) ### Changed * 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 * Replace `IntoPyTuple` with `IntoPy>`. Eventually `IntoPy` should replace `ToPyObject` and be itself implemented through `FromPy` * PyTypeObject is now a direct subtrait PyTypeCreate, removing the old cyclical implementation in [#350](https://github.com/PyO3/pyo3/pull/350) ### Removed * `PyToken` was removed due to unsoundness (See [#94](https://github.com/PyO3/pyo3/issues/94)). * Removed the unnecessary type parameter from `PyObjectAlloc` ### 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`. ## [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] - 2018-11-26 ### 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) ### 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 ### 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) ### 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 ### Fixed * Fixed compilation on nightly since `use_extern_macros` was stabilized ### Changed * PyTryFrom's error is always to `PyDowncastError` ### Removed * The pyobject_downcast macro ## [0.4.0] - 2018-07-30 ### Removed * Conversions from tuples to PyDict due to [rust-lang/rust#52050](https://github.com/rust-lang/rust/issues/52050) ### 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/) ## [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 ### 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. ### 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 ## [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 ### Fixed * Proper `c_char` usage #93 ### Changed * Rustup to 1.23.0-nightly 2017-11-07 ### 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 ### Changed * Allow to add gc support without implementing PyGCProtocol #57 * Refactor `PyErr` implementation.
