What's New in Python 3.9: Reorganize C API Changes (GH-19794)

2020-04-29T15:57:25+00:00

Move Build Changes and C API Changes to the end of the document.
Most Python users don't build Python themselves and don't use the C
API. Other changes:

* Add Build Changes section
* Add sub-sections to the C API Changes
* Sort modules in Improved Modules section: move nntplib after
  multiprocessing

bpo-40428: Remove references to Py*_ClearFreeList in the docs (GH-19783)

2020-04-29T02:41:56+00:00

They were removed from the C API in commit
ae00a5a88534fd45939f86c12e038da9fa6f9ed6.

bpo-40421: Add PyFrame_GetBack() function (GH-19765)

2020-04-29T01:28:46+00:00

New PyFrame_GetBack() function: get the frame next outer frame.

Replace frame->f_back with PyFrame_GetBack(frame) in most code but
frameobject.c, ceval.c and genobject.c.

bpo-40429: PyThreadState_GetFrame() returns a strong ref (GH-19781)

2020-04-29T01:01:43+00:00

The PyThreadState_GetFrame() function now returns a strong reference
to the frame.

bpo-40428: Remove PyTuple_ClearFreeList() function (GH-19769)

2020-04-29T00:29:20+00:00

Remove the following function from the C API:

* PyAsyncGen_ClearFreeLists()
* PyContext_ClearFreeList()
* PyDict_ClearFreeList()
* PyFloat_ClearFreeList()
* PyFrame_ClearFreeList()
* PyList_ClearFreeList()
* PySet_ClearFreeList()
* PyTuple_ClearFreeList()

Make these functions private, move them to the internal C API and
change their return type to void.

Call explicitly PyGC_Collect() to free all free lists.

Note: PySet_ClearFreeList() did nothing.

bpo-40429: PyFrame_GetCode() now returns a strong reference (GH-19773)

2020-04-28T22:56:58+00:00

Add frame_nslots() to factorize duplicate code.
