We pass all but a few of the tests in the +upstream numpy `test suite`_. + +Work proceeds at a good pace on the PyPy3.5 +version due to a grant_ from the Mozilla Foundation, and some of those +changes have been backported to PyPy2.7 where relevant + +We changed ``timeit`` to now report average +- standard deviation, which is +better than the misleading minimum value reported in CPython. + +XXX + +As always, this release fixed many issues and bugs raised by the +growing community of PyPy users. We strongly recommend updating. + +You can download the PyPy2.7 v5.6 release here: + + http://pypy.org/download.html + +We would like to thank our donors for the continued support of the PyPy +project. + +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. + +.. _`test suite`: https://bitbucket.org/pypy/pypy/wiki/Adventures%20in%20cpyext%20compatibility +.. _cffi: https://cffi.readthedocs.org +.. _grant: https://morepypy.blogspot.com/2016/08/pypy-gets-funding-from-mozilla-for.html +.. _`PyPy`: http://doc.pypy.org +.. _`RPython`: https://rpython.readthedocs.org +.. _`modules`: http://doc.pypy.org/en/latest/project-ideas.html#make-more-python-modules-pypy-friendly +.. _`help`: http://doc.pypy.org/en/latest/project-ideas.html + +What is PyPy? +============= + +PyPy is a very compliant Python interpreter, almost a drop-in replacement for +CPython 2.7. 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 release supports: + + * **x86** machines on most common operating systems + (Linux 32/64 bits, Mac OS X 64 bits, Windows 32 bits, OpenBSD, FreeBSD) + + * newer **ARM** hardware (ARMv6 or ARMv7, with VFPv3) running Linux, + + * big- and little-endian variants of **PPC64** running Linux, + + * **s390x** running Linux + +.. _`PyPy and CPython 2.7.x`: http://speed.pypy.org +.. _`dynamic languages`: http://pypyjs.org + +Other Highlights (since 5.4 released Aug 31, 2016) +========================================================= + +* New features + * Allow tests run with `-A` to find `libm.so` even if it is a script not a + dynamically loadable file + * Backport fixes to rposix on windows from py2.5 + * Allow user-defined ``__getitem__`` on subclasses of ``str`` and ``unicode`` + * Add ``inode`` to ``scandir()`` on posix systems + * Support more attributes on ``super`` + * Issue #2386: non-latin1 unicode keys were ignored in ``unicode.format(**d)`` + * Restore the ability to translate with CPython + * Update to CFFI 1.8.4 + * Support the new buffer protocol in cpyext and numpypy + * Add ``rposix.sync()`` + * Support full-precision nanosecond times in os.stat() + * Add documentation about the assembler backends to RPYthon + * Search for the stdlibs from the libpypy shared object rather than the pypy-c exe, + changes downstream packaging requirments + * Add ``try_inline``, like ``always_inline`` and ``dont_inline`` to RPython + * Reject ``'a'.strip(buffer(' '))`` like cpython (the argument to strip must + be ``str`` or ``unicode``) + * Allow ``warning.warn(('something', 1), Warning)`` like on CPython + * Refactor ``rclock`` and add some more ``CLOCK_xxx`` constants on + relevant platforms + * Backport the ``'faulthandler`` module from py3.5 + * Improve the error message when trying to call a method where the ``self`` + parameter is missing in the definition + * Implement ``rposix.cpu_count`` + * Support translation on FreeBSD running on PowerPC + * Implement ``__rmod__`` on ``str`` and ``unicode`` types + * Issue warnings for stricter handling of ``__new__``, ``__init__`` args + +* Bug Fixes + * Tweak a float comparison with 0 in `backendopt.inline` to avoid rounding errors + * Fix translation of the sandbox + * Fix for an issue where `unicode.decode('utf8', 'custom_replace')` messed up + the last byte of a unicode string sometimes + * fix some calls to functions through window's COM interface + * fix minor leak when the C call to socketpair() fails + * make sure (-1.0 + 0j).__hash__(), (-1.0).__hash__() returns -2 + * Fix for an issue where PyBytesResize was called on a fresh pyobj + * Fix bug in codewriter about passing the ``exitswitch`` variable to a call + * Don't crash in ``merge_if_blocks`` if the values are symbolics + * Issue #2325/2361: __class__ assignment between two classes with the same + slots + * Issue #2409: don't leak the file descriptor when doing ``open('some-dir')`` + * Windows fixes around vmprof + * Don't use ``sprintf()`` from inside a signal handler + * Test and fix bug from the ``guard_not_forced_2`` branch, which didn't + save the floating-point register + * ``_numpypy.add.reduce`` returns a scalar now + +* Performance improvements: + * Improve method calls on oldstyle classes + * Clean and refactor code for testing cpyext to allow sharing with py3.5 + * Refactor a building the map of reflected ops in ``_numpypy`` + * Improve merging of virtual states in the JIT in order to avoid jumping to the + preamble + * In JIT residual calls, if the called function starts with a fast-path like + ``if x.foo != 0: return x.foo``, then inline the check before doing the + ``CALL``. + * Ensure ``make_inputargs`` fails properly when given arguments with type + information + * Makes ``optimiseopt`` iterative instead of recursive so it can be reasoned + about more easily and debugging is faster + * Refactor and remove dead code from ``optimizeopt``, ``resume`` + + +.. _resolved: http://doc.pypy.org/en/latest/whatsnew-5.6.0.html + +Please update, and continue to help us make PyPy better. + +Cheers _______________________________________________ pypy-commit mailing list pypy-commit@python.org https://mail.python.org/mailman/listinfo/pypy-commit
