[New-bugs-announce] [issue41936] Remove macros Py_ALLOW_RECURSION/Py_END_ALLOW_RECURSION

[Serhiy Storchaka]

New submission from Serhiy Storchaka <storchaka+cpython at gmail.com>:

Macros Py_ALLOW_RECURSION and Py_END_ALLOW_RECURSION together with field recursion_critical of the PyInterpreterState structure were added in 5b222135f8d2492713994f2cb003980e87ce6a72 but were never documented. It seems that the reason of adding them was to work around the fact that PyDict_GetItem() can silence any exception including recursion error. But PyDict_GetItem() no longer used in that code and the macros are also no longer used (see issue41909).

GvR proposed to remove these macros. I think that recursion_critical can be removed too.
