When compiling for PyPy, Cython therefore needs a way to tell PyPy about any changes. For the tstate->curexc* fields, there are the two functions PyErrFetch() and PyErrRestore(). Could we have two similar "official" functions for the exc* fields? Maybe PyErrFetchLast() and PyErrRestoreLast()?
I wouldn't call the functions *Last, as this may cause confusion with sys.last*. I'm also unsure why the current API uses this Fetch/Restore pair of functions where Fetch clears the variables. A Get/Set pair of functions would be more natural, IMO (where Get returns "new" references). This would give PyErrGetExcInfo/PyErrSetExcInfo. Ok, I added a tracker ticket and I'm working on a patch. http://bugs.python.org/issue14098
The patch is attached to the ticket, including documentation and test. I'd be happy if someone could review it and apply it.
Thanks!
Stefan
