[issue40429] [C API] PyThreadState_GetFrame() and PyFrame_GetCode() should return a strong refrence

[STINNER Victor]

New submission from STINNER Victor <vstinner at python.org>:

I recently added PyThreadState_GetFrame() and PyFrame_GetCode() functions to the C API of Python 3.9.

Currently, these functions return borrowed references.

I asked on capi-sig and Brett confirms that borrowed refrences should be avoided:

Borrowed references should be avoidedd!

I will work on a PR to modify these functions to return a strong reference instead.
