Re: What's the public API alternative to _PyObject_GC_IS_TRACKED()?

I need it since I'm developing an immutable dict. And in dict that
function is used.

I do not understand why there's no public API for that function. It
seems very useful.

   I am repeatedly facing this issue while installing ANY pip module:



   PS D:\Documents\GitHub\mysite> pip install flask

   I have reinstalled python, and repaired but no help at all. My version of
   Python is 3.10.1



   Thank You

What does "pip --version" tell you?

I think it is useful only for optimization based on *current* Python internals.
That's why it is not a public API. If we expose it as public API, it
makes harder to change Python's GC internals.

Hi, Inada Senpai. So I do not need PyObject_GC_Track on cloning or
merging, or MAINTAIN_TRACKING on insert?
