======================== What's new in PyPy 2.6.0 ======================== .. this is a revision shortly after release-2.5.1 .. startrev: cb01edcb59414d9d93056e54ed060673d24e67c1 issue2005: ignore errors on closing random file handles while importing a module (cpython compatibility) issue2013: added constants to _ssl for TLS 1.1 and 1.2 issue2014: Add PyLong_FromUnicode to cpyext. issue2017: On non-Linux-x86 platforms, reduced the memory impact of creating a lot of greenlets/tasklets. Particularly useful on Win32 and on ARM, where you used to get a MemoryError after only 2500-5000 greenlets (the 32-bit address space is exhausted). Update gdb_pypy for python3 (gdb comatability) Merged rstrategies into rpython which provides a library for Storage Strategies Support unicode strings in numpy.dtype creation i.e. np.dtype(u'int64') Various rpython cleanups for vmprof support issue2019: Fix isspace as called by rpython unicode.strip() issue2023: In the cpyext 'Concrete Object Layer' API, don't call methods on the object (which can be overriden), but directly on the concrete base type. issue2029: Hide the default_factory attribute in a dict issue2027: Better document pyinteractive and add --withmod-time .. branch: gc-incminimark-pinning-improve branch gc-incminimark-pinning-improve: Object Pinning is now used in `bz2` and `rzlib` (therefore also affects Python's `zlib`). In case the data to compress/decompress is inside the nursery (incminimark) it no longer needs to create a non-moving copy of it. This saves one `malloc` and copying the data. Additionally a new GC environment variable is introduced (`PYPY_GC_MAX_PINNED`) primarily for debugging purposes. .. branch: refactor-pycall branch refactor-pycall: Make `*`-unpacking in RPython function calls completely equivalent to passing the tuple's elements as arguments. In other words, `f(*(a, b))` now behaves exactly like `f(a, b)`. .. branch: issue2018 branch issue2018: Allow prebuilt rpython dict with function values .. branch: vmprof .. Merged but then backed out, hopefully it will return as vmprof2 .. branch: object-dtype2 branch object-dtype2: Extend numpy dtypes to allow using objects with associated garbage collection hook .. branch: vmprof2 branch vmprof2: Add backend support for vmprof - a lightweight statistical profiler - to linux64, see client at https://vmprof.readthedocs.org .. branch: jit_hint_docs branch jit_hint_docs: Add more detail to @jit.elidable and @jit.promote in rpython/rlib/jit.py .. branch: remove-frame-debug-attrs branch remove_frame-debug-attrs: Remove the debug attributes from frames only used for tracing and replace them with a debug object that is created on-demand .. branch: can_cast branch can_cast: Implement np.can_cast, np.min_scalar_type and missing dtype comparison operations. .. branch: numpy-fixes branch numpy-fixes: Fix some error related to object dtype, non-contiguous arrays, inplement parts of __array_interface__, __array_priority__, __array_wrap__ .. branch: cells-local-stack branch cells-local-stack: Unify the PyFrame.cells and Pyframe.locals_stack_w lists, making frame objects 1 or 3 words smaller. .. branch: pythonoptimize-env branch pythonoptimize-env Implement PYTHONOPTIMIZE environment variable, fixing issue #2044 .. branch: numpy-flags branch numpy-flags Finish implementation of ndarray.flags, including str() and repr() .. branch: cffi-1.0 branch cffi-1.0 PyPy now includes CFFI 1.0. .. branch: pypyw branch pypyw PyPy on windows provides a non-console pypyw.exe as well as pypy.exe. Similar to pythonw.exe, any use of stdout, stderr without redirection will crash. .. branch: fold-arith-ops branch fold-arith-ops remove multiple adds on add chains ("1 + 1 + 1 + ...") .. branch: fix-result-types branch fix-result-types: * Refactor dtype casting and promotion rules for consistency and compatibility with CNumPy. * Refactor ufunc creation. * Implement np.promote_types().
