bpo-32137: The repr of deeply nested dict now raises a RecursionError (#4570) 
instead of crashing due to a stack overflow.

This perhaps will fix similar problems in other extension types.

bpo-32030: Add more options to _PyCoreConfig (#4485) 
Py_Main() now handles two more -X options:

* -X showrefcount: new _PyCoreConfig.show_ref_count field
* -X showalloccount: new _PyCoreConfig.show_alloc_count field

2ebc5ce42a bpo-30860: Consolidate stateful runtime globals. (#3397) 
* group the (stateful) runtime globals into various topical structs
* consolidate the topical structs under a single top-level _PyRuntimeState struct
* add a check-c-globals.py script that helps identify runtime globals

Other globals are excluded (see globals.txt and check-c-globals.py).

de4ae3d486 Backed out changeset b9c9691c72c5 
Issue #28858: The change b9c9691c72c5 introduced a regression. It seems like
_PyObject_CallArg1() uses more stack memory than
PyObject_CallFunctionObjArgs().
 2016-12-04 22:59:09 +01:00
Victor Stinner
27580c1fb5 Replace PyObject_CallFunctionObjArgs() with fastcall 
* PyObject_CallFunctionObjArgs(func, NULL) => _PyObject_CallNoArg(func)
* PyObject_CallFunctionObjArgs(func, arg, NULL) => _PyObject_CallArg1(func, arg)

PyObject_CallFunctionObjArgs() allocates 40 bytes on the C stack and requires
extra work to "parse" C arguments to build a C array of PyObject*.

_PyObject_CallNoArg() and _PyObject_CallArg1() are simpler and don't allocate
memory on the C stack.

This change is part of the fastcall project. The change on listsort() is
related to the issue #23507.

7e160ce356 Issue #23034: The output of a special Python build with defined COUNT_ALLOCS, 
SHOW_ALLOC_COUNT or SHOW_TRACK_COUNT macros is now off by  default.  It can
be re-enabled using the "-X showalloccount" option.  It now outputs to stderr
instead of stdout.

bytearray, list, tuple, set, frozenset, dict, OrderedDict, corresponding
views and os.scandir() iterator.

1ed017ae92 Issue #20440: Cleaning up the code by using Py_SETREF and Py_CLEAR. 
Old code is correct, but with Py_SETREF and Py_CLEAR it can be cleaner.
This patch doesn't fix bugs and hence there is no need to backport it.
