gh-94673: Hide Objects in PyTypeObject Behind Accessors (gh-104074)

2023-05-02T02:34:43Z

This makes it much cleaner to move more PyTypeObject fields to PyInterpreterState.

gh-81057: Move contextvars-related Globals to _PyRuntimeState (gh-99400)

2022-11-16T16:54:28Z

This is part of the effort to consolidate global variables, to make them easier to manage (and make it easier to later move some of them to PyInterpreterState).

gh-99300: Use Py_NewRef() in Python/ directory (#99317)

2022-11-10T10:23:36Z

Replace Py_INCREF() and Py_XINCREF() with Py_NewRef() and
Py_XNewRef() in C files of the Python/ directory.

Update Parser/asdl_c.py to regenerate Python/Python-ast.c.

Add more stats for freelist use and allocations. (GH-92211)

bpo-47164: Add _PyCFunction_CAST() macro (GH-32192)

2022-03-31T08:02:34Z

Use the macro in C files of the Python/ directory.

bpo-46417: Clear more static types (GH-30796)

2022-01-22T17:55:48Z

* Move PyContext static types into object.c static_types list.
* Rename PyContextTokenMissing_Type to _PyContextTokenMissing_Type
  and declare it in pycore_context.h.
* _PyHamtItems types are no long exported: replace PyAPI_DATA() with
  extern.

bpo-46008: Make runtime-global object/type lifecycle functions and state consistent. (gh-29998)

2021-12-09T19:59:26Z

This change is strictly renames and moving code around.  It helps in the following ways:

* ensures type-related init functions focus strictly on one of the three aspects (state, objects, types)
* passes in PyInterpreterState * to all those functions, simplifying work on moving types/objects/state to the interpreter
* consistent naming conventions help make what's going on more clear
* keeping API related to a type in the corresponding header file makes it more obvious where to look for it

bpo-45522: Allow to disable freelists on build time (GH-29056)

2021-10-21T13:12:20Z

Freelists for object structs can now be disabled. A new ``configure``
option ``--without-freelists`` can be used to disable all freelists
except empty tuple singleton. Internal Py*_MAXFREELIST macros can now
be defined as 0 without causing compiler warnings and segfaults.

bpo-45439: Move _PyObject_VectorcallTstate() to pycore_call.h (GH-28893)

2021-10-14T19:53:04Z

* Move _PyObject_VectorcallTstate() and _PyObject_FastCallTstate() to
  pycore_call.h (internal C API).
* Convert PyObject_CallOneArg(), PyObject_Vectorcall(),
  _PyObject_FastCall() and PyVectorcall_Function() static inline
  functions to regular functions.
* Add _PyVectorcall_FunctionInline() static inline function.
* PyObject_Vectorcall(), _PyObject_FastCall(), and
  PyObject_CallOneArg() now call _PyThreadState_GET() rather
  than PyThreadState_Get().

pycore_pystate.h no longer redefines PyThreadState_GET() (GH-28921)

2021-10-13T12:09:13Z

Redefining the PyThreadState_GET() macro in pycore_pystate.h is
useless since it doesn't affect files not including it. Either use
_PyThreadState_GET() directly, or don't use pycore_pystate.h internal
C API. For example, the _testcapi extension don't use the internal C
API, but use the public PyThreadState_Get() function instead.

Replace PyThreadState_Get() with _PyThreadState_GET(). The
_PyThreadState_GET() macro is more efficient than PyThreadState_Get()
and PyThreadState_GET() function calls which call fail with a fatal
Python error.

posixmodule.c and _ctypes extension now include  before
pycore header files (like pycore_call.h).

_PyTraceback_Add() now uses _PyErr_Fetch()/_PyErr_Restore() instead
of PyErr_Fetch()/PyErr_Restore().

The _decimal and _xxsubinterpreters extensions are now built with the
Py_BUILD_CORE_MODULE macro defined to get access to the internal C
API.
