======================================================================= PyPy v7.3.14: release of python 2.7, 3.9, and 3.10, released 2023-12-25 ======================================================================= The PyPy team is proud to release version 7.3.14 of PyPy. Highlights of this release are compatibility with HPy-0.9_, cffi 1.16, additional C-API interfaces, and more python3.10 fixes. The release includes three different interpreters: - PyPy2.7, which is an interpreter supporting the syntax and the features of Python 2.7 including the stdlib for CPython 2.7.18+ (the ``+`` is for backported security updates) - PyPy3.9, which is an interpreter supporting the syntax and the features of Python 3.9, including the stdlib for CPython 3.9.18. - PyPy3.10, which is an interpreter supporting the syntax and the features of Python 3.10, including the stdlib for CPython 3.10.13. The interpreters are based on much the same codebase, thus the multiple release. This is a micro release, all APIs are compatible with the other 7.3 releases. It follows after 7.3.13 release on Sept 29, 2023. We recommend updating. You can find links to download the v7.3.14 releases here: https://pypy.org/download.html We would like to thank our donors for the continued support of the PyPy project. If PyPy is not quite good enough for your needs, we are available for `direct consulting`_ work. If PyPy is helping you out, we would love to hear about it and encourage submissions to our blog_ via a pull request to https://github.com/pypy/pypy.org We would also like to thank our contributors and encourage new people to join the project. Since the last release we have contributions from three new contributors. PyPy has many layers and we need help with all of them: bug fixes, `PyPy`_ and `RPython`_ documentation improvements, or general `help`_ with making RPython's JIT even better. If you are a python library maintainer and use C-extensions, please consider making a HPy_ / CFFI_ / cppyy_ version of your library that would be performant on PyPy. In any case, both `cibuildwheel`_ and the `multibuild system`_ support building wheels for PyPy. .. _`PyPy`: index.html .. _`RPython`: https://rpython.readthedocs.org .. _`help`: project-ideas.html .. _CFFI: https://cffi.readthedocs.io .. _cppyy: https://cppyy.readthedocs.io .. _HPy-0.9: https://hpyproject.org/blog/posts/2023/10/hpy-0.9.0-fourth-public-release/ .. _`multibuild system`: https://github.com/matthew-brett/multibuild .. _`cibuildwheel`: https://github.com/joerick/cibuildwheel .. _blog: https://pypy.org/blog .. _HPy: https://hpyproject.org/ .. _was sponsored: https://www.pypy.org/posts/2022/07/m1-support-for-pypy.html .. _direct consulting: https://www.pypy.org/pypy-sponsors.html .. _has built: https://www.pypy.org/posts/2022/11/pypy-and-conda-forge.html What is PyPy? ============= PyPy is a Python interpreter, a drop-in replacement for CPython It's fast (`PyPy and CPython 3.7.4`_ performance comparison) due to its integrated tracing JIT compiler. We also welcome developers of other `dynamic languages`_ to see what RPython can do for them. We provide binary builds for: * **x86** machines on most common operating systems (Linux 32/64 bits, Mac OS 64 bits, Windows 64 bits) * 64-bit **ARM** machines running Linux (``aarch64``). * Apple **M1 arm64** machines (``macos_arm64``). * **s390x** running Linux PyPy support Windows 32-bit, Linux PPC64 big- and little-endian, and Linux ARM 32 bit, but does not release binaries. Please reach out to us if you wish to sponsor binary releases for those platforms. Downstream packagers provide binary builds for debian, Fedora, conda, OpenBSD, FreeBSD, Gentoo, and more. .. _`PyPy and CPython 3.7.4`: https://speed.pypy.org .. _`dynamic languages`: https://rpython.readthedocs.io/en/latest/examples.html Changelog ========= For all versions ---------------- - Use OpenSSL 3.0.12 when embedding libraries for a portable build - Add a part of CFFI 1.17. When in ABI mode, you can now use ``lib.funcname`` in many places where a ```` object was required. For instance, it can be used in a callback to a C function call, or written to a C structure field of the correct pointer-to-function type. You can also use ``ffi.cast()`` or `ffi.typeof()`` on it. - Convert all usages of ``stat64`` to ``stat``, which fixes compilation on ``>=musl-1.2.4 libc`` (:issue:`4047`) Bugfixes ~~~~~~~~ - Fix constfolding of ``str()`` without arguments (used to crash) (:issue:`4017`) - Windows: remove wrong c-level define, use standard ``include`` instead (:issue:`4023`) - Fix universal newline but non-translating ``text-io``: in this mode, two ``\r`` at the end of the file were combined into a single line by ``.readline()`` (:issue:`4037`) - Fix segfault when JITting code which skips short preamble setup (:issue:`4030`) - Align memoryview use of ``PyBUF_MAX_NDIM`` with python3 (:issue:`4040`) Speedups and enhancements ~~~~~~~~~~~~~~~~~~~~~~~~~ - Fixes for compilation with gcc 14 and clang which enforce more strict C behaviour (:issue:`4041`) - Avoid calling ``codepoints_in_utf8`` on the original input string again and again (:issue:`4027`) Python 3.9+ ----------- - Improve ``os.scandir()`` handling of symlinks on Windows - Remove extraneous debug print from ``_ssl`` (:issue:`4009`) - Update cffi backend to 1.16.0, add HPy backend to 0.9 - When creating a venv from a symlinked venv, force symlinks. Portable builds need too many shared objects to allow copying only the executables - Refactor calling finalizers in cpyext to make sure they are called Bugfixes ~~~~~~~~ - If object does not have ``__len__``, default to ``pyobj.itemcount=0`` (:issue:`4012`) - Fix ``small_int.__rpow__(large_int)`` (:issue:`4015`) - Make ``mmap.mmap.__setitem__`` accept a buffer (:issue:`4006`) - In cpyext, when re-assigning to ``type.__bases__``, rebuild the type struct (:issue:`3975`) - Remove newline in line read from ``PYPY_PORTABLE_DEPS.txt`` (:issue:`4018`) - Fix astcompiler bug where sometimes a return with a value wasn't being caught inside an async generator (:issue:`4022`) - Start implementing the ``ag_running`` logic of asynchronous generators (:issue:`3995`) - Handle ``pathlib.path`` in ``PyUnicode_FSDecoder``, ``PyUnicode_FSDecoder`` (:issue:`3168`) - Raise ``OSError`` in ``gmtime`` like in ``localtime`` - Make the construction arguments of builtin types more introspectable (:issue:`4033`) - Make sure an encoding in ``str.decode(encoding=xxx)`` does not have invalid surrogates Speedups and enhancements ~~~~~~~~~~~~~~~~~~~~~~~~~ - Follow upstream performance patch for datetime.py (:issue:`4007`) - Add ``os.getppid``, ``os.getlogin`` on windows (:issue:`4024`) - Proactively call ``bufferview.releasebuffer`` when exiting a context manager and don't wait for ``gc`` to release it. - Always initialize threads at startup, like in ``Py_Initialize`` for Cpython3.9 - Add a ``NULL`` byte to ``bytearray`` data, like CPython. (:issue:`4029`) - Add ``hidden_applevel`` to ``_contextvars.Context.run``. Discovered in django PR 17500 to revive PyPy support in django - Add window API functions ``PyErr_SetFromWindowsErrWithFilename``, ``PyErr_SetExcFromWindowsErrWithFilenameObject``, ``PyErr_SetExcFromWindowsErrWithFilenameObjects`` (:issue:`4034`) Python 3.10 ----------- Bugfixes ~~~~~~~~ - ``LIST_EXTEND`` bytecode should just let all exceptions through if the second argument is iterable (:issue:`4031`) - Pattern matching classes now use the full ``isinstance`` machinery, calling ``__instancecheck__`` too.
