... and there also were some more headers missing, so basically, this
feature never worked. Great. Here's the complete implementation with the
four header files that I had to add at the top:
"""
#include <new>
#include <typeinfo>
#include <stdexcept>
#include <iostream>
static void __Pyx_CppExn2PyErr() {
// Catch a handful of different errors here and turn them into the
// equivalent Python errors.
try {
if (PyErr_Occurred())
; // let the latest Python exn pass through and ignore the current one
else
throw;
} catch (const std::bad_alloc& exn) {
PyErr_SetString(PyExc_MemoryError, exn.what());
} catch (const std::bad_cast& exn) {
PyErr_SetString(PyExc_TypeError, exn.what());
} catch (const std::domain_error& exn) {
PyErr_SetString(PyExc_ValueError, exn.what());
} catch (const std::invalid_argument& exn) {
PyErr_SetString(PyExc_ValueError, exn.what());
} catch (const std::ios_base::failure& exn) {
PyErr_SetString(PyExc_IOError, exn.what());
} catch (const std::out_of_range& exn) {
// Change out_of_range to IndexError
PyErr_SetString(PyExc_IndexError, exn.what());
} catch (const std::overflow_error& exn) {
PyErr_SetString(PyExc_OverflowError, exn.what());
} catch (const std::range_error& exn) {
PyErr_SetString(PyExc_ArithmeticError, exn.what());
} catch (const std::underflow_error& exn) {
PyErr_SetString(PyExc_ArithmeticError, exn.what());
} catch (const std::exception& exn) {
PyErr_SetString(PyExc_RuntimeError, exn.what());
}
catch (...)
{
PyErr_SetString(PyExc_RuntimeError, "Unknown exception");
}
}
"""

Does it make sense to always include these four headers, or should we try
to handle the exceptions conditionally?
