When Python is built in debug mode (Py_REF_DEBUG macro), Py_INCREF()
and Py_DECREF() of the limited C API 3.9 (and older) now call
Py_IncRef() and Py_DecRef(), since _Py_IncRef() and _Py_DecRef() were
added to Python 3.10.
(cherry picked from commit 7ba0fd9)
Py_INCREF() was made compatible again with Python 3.9 and older in
the limited API of Python debug mode.
(cherry picked from commit 58e4b69)
⚠️⚠️⚠️ Buildbot failure ⚠️⚠️⚠️
Hi! The buildbot AMD64 Arch Linux TraceRefs 3.12 has failed when building commit d29e86b.
What do you need to do:
- Don't panic.
- Check the buildbot page in the devguide if you don't know what the buildbots are or how they work.
- Go to the page of the buildbot that failed (https://buildbot.python.org/all/#builders/1197/builds/58) and take a look at the build logs.
- Check if the failure is related to this commit (d29e86b) or if it is a false positive.
- If the failure is related to this commit, please, reflect that on the issue and make a new Pull Request with a fix.
You can take a look at the buildbot page here:

Note: switching to 'd29e86bea3bcd7a8379d8368b36c718ab7b5b3f3'.
You are in 'detached HEAD' state. You can look around, make experimental
changes and commit them, and you can discard any commits you make in this
state without impacting any branches by switching back to a branch.
If you want to create a new branch to retain commits you create, you may
do so (now or later) by using -c with the switch command. Example:
git switch -c <new-branch-name>
Or undo this operation with:
git switch -
Turn off this advice by setting config variable advice.detachedHead to false
HEAD is now at d29e86bea3 [3.12] gh-102304: Fix Py_INCREF() for limited C API 3.9 (#105553)
