Would it be possible to revert the change until Cython and numpy are ready for
it?
> bpo-45711: Remove type and traceback from exc_info (GH-30122)
This change broke numpy which uses C code generated by Cython for coroutines in
numpy/random/_mt19937.c (file generated from numpy/random/_mt19937.pyx).
Example of Cython code which no fails with a compiler error since
exc_info->exc_type has been removed:
/* GetTopmostException */
#if CYTHON_USE_EXC_INFO_STACK
static _PyErr_StackItem *
__Pyx_PyErr_GetTopmostException(PyThreadState *tstate)
{
_PyErr_StackItem *exc_info = tstate->exc_info;
while ((exc_info->exc_type == NULL || exc_info->exc_type == Py_None) &&
exc_info->previous_item != NULL)
{
exc_info = exc_info->previous_item;
}
return exc_info;
}
#endif
I propose this plan:
* (1) Revert this specific change
* (2) Wait until a change is merged in Cython 0.29.x
* (3) Wait until a new Cython 0.29.x version is released
* (4) Wait until numpy is released with regenerated code compatible with this
change
* (5) Apply again the change
It should increase the number of packages when Python 3.11 will be released.
In Cython, the issue is tracked as: https://github.com/cython/cython/issues/4500
