=========================
What's new in PyPy2.7 5.3
=========================
.. this is a revision shortly after release-5.1
.. startrev: aa60332382a1
.. branch: techtonik/introductionrst-simplify-explanation-abo-1460879168046
.. branch: gcheader-decl
Reduce the size of generated C sources.
.. branch: remove-objspace-options
Remove a number of options from the build process that were never tested and
never set. Fix a performance bug in the method cache.
.. branch: bitstring
JIT: use bitstrings to compress the lists of read or written descrs
that we attach to EffectInfo. Fixes a problem we had in
remove-objspace-options.
.. branch: cpyext-for-merge
Update cpyext C-API support After this branch, we are almost able to support
upstream numpy via cpyext, so we created (yet another) fork of numpy at
github.com/pypy/numpy with the needed changes. Among the significant changes
to cpyext:
- allow c-snippet tests to be run with -A so we can verify we are compatible
- fix many edge cases exposed by fixing tests to run with -A
- issequence() logic matches cpython
- make PyStringObject and PyUnicodeObject field names compatible with cpython
- add prelminary support for PyDateTime_*
- support PyComplexObject, PyFloatObject, PyDict_Merge, PyDictProxy,
PyMemoryView_*, _Py_HashDouble, PyFile_AsFile, PyFile_FromFile,
- PyAnySet_CheckExact, PyUnicode_Concat
- improve support for PyGILState_Ensure, PyGILState_Release, and thread
primitives, also find a case where CPython will allow thread creation
before PyEval_InitThreads is run, dissallow on PyPy
- create a PyObject-specific list strategy
- rewrite slot assignment for typeobjects
- improve tracking of PyObject to rpython object mapping
- support tp_as_{number, sequence, mapping, buffer} slots
(makes the pypy-c bigger; this was fixed subsequently by the
share-cpyext-cpython-api branch)
.. branch: share-mapdict-methods-2
Reduce generated code for subclasses by using the same function objects in all
generated subclasses.
.. branch: share-cpyext-cpython-api
.. branch: cpyext-auto-gil
CPyExt tweak: instead of "GIL not held when a CPython C extension module
calls PyXxx", we now silently acquire/release the GIL. Helps with
CPython C extension modules that call some PyXxx() functions without
holding the GIL (arguably, they are theorically buggy).
.. branch: cpyext-test-A
Get the cpyext tests to pass with "-A" (i.e. when tested directly with
CPython).
.. branch: oefmt
.. branch: cpyext-werror
Compile c snippets with -Werror in cpyext
.. branch: gc-del-3
Add rgc.FinalizerQueue, documented in pypy/doc/discussion/finalizer-order.rst.
It is a more flexible way to make RPython finalizers.
.. branch: unpacking-cpython-shortcut
.. branch: cleanups
.. branch: cpyext-more-slots
.. branch: use-gc-del-3
Use the new rgc.FinalizerQueue mechanism to clean up the handling of
``__del__`` methods. Fixes notably issue #2287. (All RPython
subclasses of W_Root need to use FinalizerQueue now.)
.. branch: ufunc-outer
Implement ufunc.outer on numpypy
.. branch: verbose-imports
Support ``pypy -v``: verbose imports. It does not log as much as
cpython, but it should be enough to help when debugging package layout
problems.
.. branch: cpyext-macros-cast
Fix some warnings when compiling CPython C extension modules
.. branch: syntax_fix
.. branch: remove-raisingops
Remove most of the _ovf, _zer and _val operations from RPython. Kills
quite some code internally, and allows the JIT to do better
optimizations: for example, app-level code like ``x / 2`` or ``x % 2``
can now be turned into ``x >> 1`` or ``x & 1``, even if x is possibly
negative.
.. branch: cpyext-old-buffers
Generalize cpyext old-style buffers to more than just str/buffer, add support for mmap
.. branch: numpy-includes
Move _numpypy headers into a directory so they are not picked up by upstream numpy, scipy
This allows building upstream numpy and scipy in pypy via cpyext
.. branch: traceviewer-common-merge-point-formats
Teach RPython JIT's off-line traceviewer the most common ``debug_merge_point`` formats.
.. branch: cpyext-pickle
Enable pickling of W_PyCFunctionObject by monkeypatching pickle.Pickler.dispatch
at cpyext import time
.. branch: nonmovable-list
Add a way to ask "give me a raw pointer to this list's
items". Only for resizable lists of primitives. Turns the GcArray
nonmovable, possibly making a copy of it first.
.. branch: cpyext-ext
Finish the work already partially merged in cpyext-for-merge. Adds support
for ByteArrayObject using the nonmovable-list, which also enables
buffer(bytearray(<some-list>))
