Hi everyone,
It's time for yet another PEP :)
Fortunately, this one is a small one that doesn't change much.
It's aim is to make the VM more robust.
On the principle, no objection.
In practice, can you show how an implementation of Py_CheckStackDepth()
would look like?
It would depend on the platform, but a portable-ish implementation is here:
https://github.com/markshannon/cpython/blob/pep-overflow-implementation/Include/internal/pycore_ceval.h#L71
Also, what is the `headroom` argument in
Py_CheckStackDepthWithHeadroom() supposed to represent? Bytes? Stack
frames?
Bytes. I'll update the PEP.
Regards
Antoine.
