[issue32797] Tracebacks from Cython modules no longer work

Stefan Behnel added the comment: FWIW, I can see that Cython is a special case because it can control the source line mapping and reporting through the C-API. Other code generators might not be able to do that, e.g. for a DSL or template language that gets translated to Python code, for

[issue32797] Tracebacks from Cython modules no longer work

Nick Coghlan added the comment: Regarding PEP 302 compliance: until Python 3.3, the builtin import system wasn't present on sys.metapath - it was its own implicit legacy thing. The change in Python 3.3 was to fix that, and make it work based on a handful of default sys.metapath entries. Not

[issue34284] Nonsensical exception message when calling `__new__` on non-instaniable objects

Nick Coghlan added the comment: Agreed, but it's still a definition time bug, as the types are only nulling out tp_new after creating the singleton instance, and not preventing __new__ from resolving. If they *don't* null out tp_new, but instead set tp_new to a common helper function that

[issue22852] urllib.parse wrongly strips empty #fragment, ?query, //netloc

Martin Panter added the comment: I like this option. I suppose choosing which option to take is a compromise between compatiblity and simplicity. In the short term, the “allows_none” option requires user code to be updated. In the long term it may break compatibility. But the “has_netloc”

ppperry added the comment: The problem doesn't just happen with `sys.flags`, though. It happens with all types that can't be created directly by python. Ex: frame objects, generators, cells, etc. The bug is that in types whose c-level tp_new is null, the python-level __new__ is inherited

[issue34309] Trouble when reloading extension modules.
