Feature or enhancement

Proposal:

The existing PySys_GetObject() function has two issues:

• It returns a borrowed reference.
• It ignores errors.

I propose adding new functions PySys_GetAttr() and PySys_GetAttrString() to get a sys module attribute which return a strong reference and don't ignore errors.

API:

PyObject *PySys_GetAttr(PyObject *name)
PyObject *PySys_GetAttrString(const char *name)

• Return a new object (strong reference) on success.

• Set an exception and return NULL on error:

  • Set an AttributeError if the attribute doesn't exist.
  • Set a RuntimeError if the sys module cannot be retrieved.

Has this already been discussed elsewhere?
