======================== What's new in PyPy 2.2.1 ======================== .. this is a revision shortly after release-2.2.x .. startrev: 4cd1bc8b3111 .. branch: release-2.2.x .. branch: numpy-newbyteorder Clean up numpy types, add newbyteorder functionality .. branch: windows-packaging Package tk/tcl runtime with win32 .. branch: armhf-singlefloat JIT support for singlefloats on ARM using the hardfloat ABI .. branch: voidtype_strformat Better support for record numpy arrays .. branch: osx-eci-frameworks-makefile OSX: Ensure frameworks end up in Makefile when specified in External compilation info .. branch: less-stringly-ops Use subclasses of SpaceOperation instead of SpaceOperator objects. Random cleanups in flowspace and annotator. .. branch: ndarray-buffer adds support for the buffer= argument to the ndarray ctor .. branch: better_ftime_detect2 On OpenBSD do not pull in libcompat.a as it is about to be removed. And more generally, if you have gettimeofday(2) you will not need ftime(3). .. branch: timeb_h Remove dependency upon on OpenBSD. This will be disappearing along with libcompat.a. .. branch: OlivierBlanvillain/fix-3-broken-links-on-pypy-published-pap-1386250839215 Fix 3 broken links on PyPy published papers in docs. .. branch: jit-ordereddict .. branch: refactor-str-types Remove multimethods on str/unicode/bytearray and make the implementations share code. .. branch: remove-del-from-generatoriterator Speed up generators that don't yield inside try or wait blocks by skipping unnecessary cleanup. .. branch: annotator Remove FlowObjSpace. Improve cohesion between rpython.flowspace and rpython.annotator. .. branch: detect-immutable-fields mapdicts keep track of whether or not an attribute is every assigned to multiple times. If it's only assigned once then an elidable lookup is used when possible. .. branch: precompiled-headers Create a Makefile using precompiled headers for MSVC platforms. The downside is a messy nmake-compatible Makefile. Since gcc shows minimal speedup, it was not implemented. .. branch: camelot With a properly configured 256-color terminal (TERM=...-256color), the Mandelbrot set shown during translation now uses a range of 50 colours. Essential! .. branch: NonConstant Simplify implementation of NonConstant. .. branch: array-propagate-len Kill some guards and operations in JIT traces by adding integer bounds propagation for getfield_(raw|gc) and getarrayitem_(raw|gc). .. branch: optimize-int-and Optimize away INT_AND with constant mask of 1s that fully cover the bitrange of other operand. .. branch: bounds-int-add-or Propagate appropriate bounds through INT_(OR|XOR|AND) operations if the operands are positive to kill some guards .. branch: remove-intlong-smm kills int/long/smalllong/bool multimethods .. branch: numpy-refactor Cleanup micronumpy module .. branch: int_w-refactor In a lot of places CPython allows objects with __int__ and __float__ instead of actual ints and floats, while until now pypy disallowed them. We fix it by making space.{int_w,float_w,etc.} accepting those objects by default, and disallowing conversions only when explicitly needed. .. branch: test-58c3d8552833 Fix for getarrayitem_gc_pure optimization .. branch: simple-range-strategy Implements SimpleRangeListStrategy for case range(n) where n is a positive number. Makes some traces nicer by getting rid of multiplication for calculating loop counter and propagates that n > 0 further to get rid of guards. .. branch: popen-pclose Provide an exit status for popen'ed RFiles via pclose .. branch: stdlib-2.7.6 Update stdlib to v2.7.6 .. branch: virtual-raw-store-load Support for virtualizing raw_store/raw_load operations .. branch: refactor-buffer-api Separate the interp-level buffer API from the buffer type exposed to app-level. The `Buffer` class is now used by `W_MemoryView` and `W_Buffer`, which is not present in Python 3. Previously `W_Buffer` was an alias to `Buffer`, which was wrappable itself. .. branch: improve-consecutive-dict-lookups Improve the situation when dict lookups of the same key are performed in a chain .. branch: add_PyErr_SetFromErrnoWithFilenameObject_try_2 .. branch: test_SetFromErrnoWithFilename_NULL .. branch: test_SetFromErrnoWithFilename__tweaks .. branch: refactor_PyErr_SetFromErrnoWithFilename Add support for PyErr_SetFromErrnoWithFilenameObject to cpyext .. branch: win32-fixes4 fix more tests for win32 .. branch: latest-improve-doc Fix broken links in documentation .. branch: ast-issue1673 fix ast classes __dict__ are always empty problem and fix the ast deepcopy issue when there is missing field .. branch: issue1514 Fix issues with reimporting builtin modules .. branch: numpypy-nditer Implement the core of nditer, without many of the fancy flags (external_loop, buffered) .. branch: numpy-speed Separate iterator from its state so jit can optimize better .. branch: numpy-searchsorted Implement searchsorted without sorter kwarg .. branch: openbsd-lib-prefix add 'lib' prefix to link libraries on OpenBSD .. branch: small-unroll-improvements Improve optimization of small allocation-heavy loops in the JIT .. branch: reflex-support .. branch: asmosoinio/fixed-pip-installation-url-github-githu-1398674840188 .. branch: lexer_token_position_class .. branch: refactor-buffer-api Properly implement old/new buffer API for objects and start work on replacing bufferstr usage .. branch: issue1430 Add a lock for unsafe calls to gethostbyname and gethostbyaddr .. branch: fix-tpname Changes hacks surrounding W_TypeObject.name to match CPython's tp_name .. branch: tkinter_osx_packaging OS/X specific header path
