bpo-27961: Replace PY_LLONG_MAX, PY_LLONG_MIN and PY_ULLONG_MAX with standard macros (GH-15385)

2019-12-05T14:55:28+00:00

Use standard constants LLONG_MIN, LLONG_MAX and ULLONG_MAX.

bpo-36854: Fix refleak in subinterpreter (GH-17331)

2019-11-22T09:58:00+00:00

finalize_interp_clear() now explicitly clears the codec registry and
then trigger a GC collection to clear all references.

bpo-27961: Replace PY_LONG_LONG with long long. (GH-15386)

2019-10-21T06:49:48+00:00

bpo-38006: Add unit test for weakref clear bug (GH-16788)

2019-10-16T03:56:48+00:00

bpo-36389: _PyObject_CheckConsistency() available in release mode (GH-16612)

2019-10-07T16:42:01+00:00

bpo-36389, bpo-38376: The _PyObject_CheckConsistency() function is
now also available in release mode. For example, it can be used to
debug a crash in the visit_decref() function of the GC.

Modify the following functions to also work in release mode:

* _PyDict_CheckConsistency()
* _PyObject_CheckConsistency()
* _PyType_CheckConsistency()
* _PyUnicode_CheckConsistency()

Other changes:

* _PyMem_IsPtrFreed(ptr) now also returns 1 if ptr is NULL
  (equals to 0).
* _PyBytesWriter_CheckConsistency() now returns 1 and is only used
  with assert().
* Reorder _PyObject_Dump() to write safe fields first, and only
  attempt to render repr() at the end.

bpo-38321: Fix _testcapimodule.c warning (GH-16494)

2019-09-30T19:14:26+00:00

Fix the following warning:

    modules\_testcapimodule.c(6409):
    warning C4146: unary minus operator applied to unsigned type,
    result still unsigned

bpo-38140: Make dict and weakref offsets opaque for C heap types (#16076)

2019-09-19T16:29:05+00:00

* Make dict and weakref offsets opaque for C heap types

* Add news

bpo-38150 Fix refleak in the finalizer of a _testcapimodule type (GH-16115)

2019-09-13T16:48:03+00:00

The PyLong created in the finalizer was not being cleaned up

bpo-37879: Fix warnings in _testcapimodule (GH-16004)

bpo-37879: Suppress subtype_dealloc decref when base type is a C heap type (GH-15323)

2019-09-11T09:17:13+00:00

The instance destructor for a type is responsible for preparing
an instance for deallocation by decrementing the reference counts
of its referents.

If an instance belongs to a heap type, the type object of an instance
has its reference count decremented while for static types, which
are permanently allocated, the type object is unaffected by the
instance destructor.

Previously, the default instance destructor searched the class
hierarchy for an inherited instance destructor and, if present,
would invoke it.

Then, if the instance type is a heap type, it would decrement the
reference count of that heap type.  However, this could result in the
premature destruction of a type because the inherited instance
destructor should have already decremented the reference count
of the type object.

This change avoids the premature destruction of the type object
by suppressing the decrement of its reference count when an
inherited, non-default instance destructor has been invoked.

Finally, an assertion on the Py_SIZE of a type was deleted.  Heap
types have a non zero size, making this into an incorrect assertion.
