I don't think it is silly: if "None" means that the loader cannot provide the source, then it makes sense to continue looking for the source. If "None" means that there is certainly no source, then it does not make sense to continue looking. > On the other hand, what is Cython source code even doing on sys.path? It's specifically installed for tracebacks (and other debugging). In a way, it's no different from installing both .py and .pyc files. Nobody questions that, even though the .pyc files are sufficient. > I sort of understand the benefit, but it does seem to be a practice peculiar > to one scenario Sure, it's particular but it's a real existing scenario. > and I'm not sure the standard library should deal with it. Depends what you mean with "deal with it". Basically, all that I'm asking for is at least one officially supported way to enable finding sources for extension modules. There are many possible ways to fix this, that's why I made this post to python-ideas. > I'm struggling to see how a Python programmer would benefit from access to > the source code of a compiled extension anyway. Cython code looks very much like Python. Very likely, a Python programmer would understand the Cython code. Anyway, this is besides the point: even if it just benefits the author of the Cython code, it's already useful. > it's not exactly an urgent issue. I never proposed to make it a release blocker :-) It's not urgent but it should still be fixed. > Cython still needs to work around the issue for users of older Pythons. No. Older versions already work because there is no ExtensionFileLoader. The changes in Python 3.x(?) actually broke this. Certainly in Python 2.7, those tracebacks work fine. ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue32797> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
