bpo-28254: Add a C-API for controlling the GC state (GH-25687)

2021-04-28T16:12:16+00:00

Add new C-API functions to control the state of the garbage collector:
PyGC_Enable(), PyGC_Disable(), PyGC_IsEnabled(),
corresponding to the functions in the gc module.

bpo-43439: Wrapt the tuple in the audit events for the gc module (GH-24836)

2021-03-14T03:04:47+00:00

bpo-43439: Add audit hooks for gc functions (GH-24794)

bpo-43268: Pass interp rather than tstate to internal functions (GH-24580)

2021-02-19T14:10:45+00:00

Pass the current interpreter (interp) rather than the current Python
thread state (tstate) to internal functions which only use the
interpreter.

Modified functions:

* _PyXXX_Fini() and _PyXXX_ClearFreeList() functions
* _PyEval_SignalAsyncExc(), make_pending_calls()
* _PySys_GetObject(), sys_set_object(), sys_set_object_id(), sys_set_object_str()
* should_audit(), set_flags_from_config(), make_flags()
* _PyAtExit_Call()
* init_stdio_encoding()
* etc.

bpo-35134, Include: Move pytime.h to cpython/pytime.h (GH-23988)

2021-02-16T12:04:38+00:00

This change is backward compatible since C extension modules
must not include "pytime.h" directly, but only include "Python.h".

bpo-42519: Replace PyObject_MALLOC() with PyObject_Malloc() (GH-23587)

2020-12-01T09:37:39+00:00

No longer use deprecated aliases to functions:

* Replace PyObject_MALLOC() with PyObject_Malloc()
* Replace PyObject_REALLOC() with PyObject_Realloc()
* Replace PyObject_FREE() with PyObject_Free()
* Replace PyObject_Del() with PyObject_Free()
* Replace PyObject_DEL() with PyObject_Free()

bpo-42208: Call GC collect earlier in PyInterpreterState_Clear() (GH-23044)

2020-10-30T21:51:02+00:00

The last GC collection is now done before clearing builtins and sys
dictionaries. Add also assertions to ensure that gc.collect() is no
longer called after _PyGC_Fini().

Pass also the tstate to PyInterpreterState_Clear() to pass the
correct tstate to _PyGC_CollectNoFail() and _PyGC_Fini().

bpo-42208: Pass tstate to _PyGC_CollectNoFail() (GH-23038)

2020-10-30T16:00:00+00:00

Move private _PyGC_CollectNoFail() to the internal C API.

Remove the private _PyGC_CollectIfEnabled() which was just an alias
to the public PyGC_Collect() function since Python 3.8.

Rename functions:

* collect() => gc_collect_main()
* collect_with_callback() => gc_collect_with_callback()
* collect_generations() => gc_collect_generations()

bpo-40521: Make dict free lists per-interpreter (GH-20645)

2020-06-23T09:33:18+00:00

Each interpreter now has its own dict free list:

* Move dict free lists into PyInterpreterState.
* Move PyDict_MAXFREELIST define to pycore_interp.h
* Add _Py_dict_state structure.
* Add tstate parameter to _PyDict_ClearFreeList() and _PyDict_Fini().
* In debug mode, ensure that the dict free lists are not used after
  _PyDict_Fini() is called.
* Remove "#ifdef EXPERIMENTAL_ISOLATED_SUBINTERPRETERS".
