The following code causes an assertion failure in FutureObj_finalize() (in Modules/_asynciomodule.c): import asyncio asyncio.Future()._log_traceback = True Maybe we should allow Python code to only set it to False, and raise a ValueError in case Python code tries to set it to True? (PR 2050 made _log_traceback writable. Are there any usecases for setting it to True from Python code?)
> _log_traceback is a private property and asyncio implementation detail, you should never touch it. But still, we shouldn't let Python crash if someone sets it. I'll make a PR to fix this the way Oren proposed. Andrew, let's discuss later with what we want to replace _log_traceback. I don't like that it's a semi-public thing.
