bpo-40523: Add pass-throughs for hash() and reversed() to weakref.proxy objects (GH-19946)

2020-05-05T21:58:19+00:00

bpo-40268: Remove unused structmember.h includes (GH-19530)

2020-04-15T00:35:41+00:00

If only offsetof() is needed: include stddef.h instead.

When structmember.h is used, add a comment explaining that
PyMemberDef is used.

bpo-39481: Make weakref and WeakSet generic (GH-19497)

2020-04-14T04:54:40+00:00

bpo-40170: PyObject_GET_WEAKREFS_LISTPTR() becomes a function (GH-19377)

2020-04-06T12:07:02+00:00

Convert the PyObject_GET_WEAKREFS_LISTPTR() macro to a function to
hide implementation details: the macro accessed directly to the
PyTypeObject.tp_weaklistoffset member.

Add _PyObject_GET_WEAKREFS_LISTPTR() static inline function to the
internal C API.

bpo-39245: Switch to public API for Vectorcall (GH-18460)

2020-02-11T16:46:57+00:00

The bulk of this patch was generated automatically with:

    for name in \
        PyObject_Vectorcall \
        Py_TPFLAGS_HAVE_VECTORCALL \
        PyObject_VectorcallMethod \
        PyVectorcall_Function \
        PyObject_CallOneArg \
        PyObject_CallMethodNoArgs \
        PyObject_CallMethodOneArg \
    ;
    do
        echo $name
        git grep -lwz _$name | xargs -0 sed -i "s/\b_$name\b/$name/g"
    done

    old=_PyObject_FastCallDict
    new=PyObject_VectorcallDict
    git grep -lwz $old | xargs -0 sed -i "s/\b$old\b/$new/g"

and then cleaned up:

- Revert changes to in docs & news
- Revert changes to backcompat defines in headers
- Nudge misaligned comments

bpo-39573: Add Py_SET_TYPE() function (GH-18394)

2020-02-07T08:17:07+00:00

Add Py_SET_TYPE() function to set the type of an object.

bpo-39573: Use Py_REFCNT() macro (GH-18388)

2020-02-06T23:38:59+00:00

Replace direct acccess to PyObject.ob_refcnt with usage of the
Py_REFCNT() macro.

bpo-38395: Fix ownership in weakref.proxy methods (GH-16632)

2019-10-08T15:30:50+00:00

The implementation of weakref.proxy's methods call back into the Python
API using a borrowed references of the weakly referenced object
(acquired via PyWeakref_GET_OBJECT). This API call may delete the last
reference to the object (either directly or via GC), leaving a dangling
pointer, which can be subsequently dereferenced.

To fix this, claim a temporary ownership of the referenced object when
calling the appropriate method. Some functions because at the moment they
do not need to access the borrowed referent, but to protect against
future changes to these functions, ownership need to be fixed in
all potentially affected methods.
