We recommend using CFFI +rather than c-extensions to interact with C. + +The built-in ``_cppyy`` module was upgraded to 1.10.6, which +provides, among others, better template resolution, stricter ``enum`` handling, +anonymous struct/unions, cmake fragments for distribution, optimizations for +PODs, and faster wrapper calls. We reccomend using cppyy_ for performant +wrapping of C++ code for Python. + +The vendored pyrepl package for interaction inside the REPL was updated. + +Support for codepage encoding and decoding was added for Windows. + +As always, this release fixed several issues and bugs raised by the growing +community of PyPy users. We strongly recommend updating. Many of the fixes are +the direct result of end-user bug reports, so please continue reporting issues +as they crop up. + +You can download the v7.3 releases here: + + http://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. + +We would also like to thank our contributors and encourage new people to join +the project. PyPy has many layers and we need help with all of them: `PyPy`_ +and `RPython`_ documentation improvements, tweaking popular modules to run +on pypy, or general `help`_ with making RPython's JIT even better. Since the +previous release, we have accepted contributions from 27 new contributors, +thanks for pitching in. + +.. _`PyPy`: index.html +.. _`RPython`: https://rpython.readthedocs.org +.. _`help`: project-ideas.html +.. _`CFFI`: http://cffi.readthedocs.io +.. _`cppyy`: https://cppyy.readthedocs.io +.. _`available as wheels`: https://github.com/antocuni/pypy-wheels + +What is PyPy? +============= + +PyPy is a very compliant Python interpreter, almost a drop-in replacement for +CPython 2.7, 3.6. It's fast (`PyPy and CPython 2.7.x`_ 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. + +This PyPy release supports: + + * **x86** machines on most common operating systems + (Linux 32/64 bits, Mac OS X 64 bits, Windows 32 bits, OpenBSD, FreeBSD) + + * big- and little-endian variants of **PPC64** running Linux, + + * **s390x** running Linux + + * 64-bit **ARM** machines running Linux. + +Unfortunately at the moment of writing our ARM buildbots are out of service, +so for now we are **not** releasing any binary for the ARM architecture (32 +bit), although PyPy does support ARM 32 bit processors. + +.. _`PyPy and CPython 2.7.x`: http://speed.pypy.org +.. _`dynamic languages`: http://rpython.readthedocs.io/en/latest/examples.html + + +Changelog +========= + +Changes shared across versions +------------------------------ + +* Fix segfault when calling descr-methods with no arguments +* Change the SOABI and subsequently change the reported ABI tag. +* Update the builtin ``_cppyy`` backend to 1.10.6 +* Performance improvements in string/unicode handling +* Fix compilation error when building `revdb`_ (`issue 3084`_, actually + released in PyPy 7.2 but not mentioned in the release notes) +* Add JIT options to documentation and an option for JIT help via ``pypy --jit + help`` +* Fix regex escapes in pyrepl (`issue 3097`_) +* Allow reloading of subclasses of module (`issue 3099`_) +* Work around a gcc bug, which was reported to them and fixed (`issue 3086`_) +* Fix (again) faulty logic when decoding invalid UTF-8 (`issue 2389`_) +* Fix up LICENSE file +* Turn all ``http`` links in the documentation to ``https`` +* Update the bndled pip and setuptools (used in ``pypy -mensurepip`` to version + that support `manylinux2010`_ wheels +* Link the ``DEFAULT_SOABI`` to the ``PYPY_VERSION`` +* Workaround for programs calling ``sys.setrecursionlimit(huge_value)`` (`issue + 3094`_) +* Set minimal ``MACOSX_DEPLOYMENT_TARGET`` to 10.7 on macOS; cpython uses 10.5 +* Fix a JIT bug causing rare register corruption on aarch64 +* Add discovery of ``ncursesw`` when building ``_minimal_curses`` and improve + handling of old curses versions (`issue 2970`_) +* Improve the error message for ``class X(random_object)`` (`issue 3109`_) +* Deal with json dicts containing repeated keys in the new map based parser + (`issue 3108`_) +* Port parts of the `portable pypy`_ repackaging scripts to add an option for + ``RPATH`` manipulation on linux +* Check for overflow in ctypes array creation +* Better support and report MSVC versions used to compile on windows +* Allow any kind of buffer in socket.setsockopt(), like CPython (`issue 3114`_) + +C-API (cpyext) and c-extensions +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + +* Add ``_PySet_Next``, ``_PySet_NextEntry`` +* Correctly swallow exceptions happening inside ``PyDict_GetItem()`` (`issue + 3098`_) +* Respect tp_dict on PyType_Ready (`issue XXX`_) +* Allow calling ``PyType_Ready`` on a subclass with a partially built + ``tp_base`` (issue 3117`_) +* Rename ``tuple_new`` to ``_PyPy_tuple_new`` to follow the naming convention of + exported symbols in ``libpypy-c.so`` +* Actually restore the traceback in ``PyErr_Restore`` (`issue 3120`_) + +Python 3.6 only +--------------- + +* Don't grow the ``lzma.decompress()`` buffer past ``max_length`` (`issue 3088`_) +* Backport fix from CPython for failure of ``lzma`` to decompress a file + (`issue 3090`_) +* Fix ``asyncgen_hooks`` and refactor ``coroutine execution`` +* Fix range checking in GB18030 decoder (CPython issue `29990`_) +* Fix handling escape characters in HZ codec (CPython issue `30003`_) +* Reject null characters in a few more functions (CPython issue `13617`_) +* Fix build on macOS without ``clock_gettime`` (before 10.12 and xcode 8, + released 2016) +* Backport 3.7.5 changes to ``timedelta.__eq__`` and ``time.__eq__`` (CPython + issue `37579`_) +* Backport more fixes to comparisons in ``datetime.py`` (CPython issue `37985`_) +* Use the python tag in ``pyc`` file names, not the abi tag +* Handle string formatting with a single ``[`` in the format string (`issue + 3100`_) +* Backport some of the patches in `macports pypy`_ +* Add missing ``HAVE_FACCESSAT`` to ``posix._have_functions`` +* Update pyrepl from upstream package (`issue 2971`_) +* Fix ``PyFrame._guess_function_name_parens()`` +* Fix range of allowed years in ``time.mktime`` to match CPython `13312`_ +* Generators need to store the old current ``exc_info`` in a place that is + visible, because in one corner case a call to ``sys.exc_info()`` might need + it.
