The tp_finalize C API doc used PyErr_Fetch and PyErr_Restore in its example code. That API was deprecated in 3.12. Update to point to the suggested replacement function PyErr_GetRaisedException which has a sample usage.

There was a problem hiding this comment.
"non-trivial" is not accurate. You can have a lot of code which doesn't raise exceptions, and short code which raises exceptions. I prefer to keep the previous sentence.

CI / Github Actions workflow seems to have failed due to some restructuring (https://github.com/python/cpython/actions/runs/13864492893), looks like needs an update branch, should I do that? |

The
tp_finalizeC API doc currently uses the older PyErr_Fetch + PyErr_Restore API to stash the current exception in its sample implementation. That API was deprecated in 3.12.Update to point to the suggested replacement function PyErr_GetRaisedException which has a sample usage.
