I just posted a draft PR that implements the narrower fix: https://github.com/python/cpython/pull/20287 I confirmed that the Django test passes with it. I also included two regression tests: one using only generators, and one more like the Django test that awaits a task. My solution was to update the exception context in gen_send_ex() using _PyErr_SetObject() instead of _PyErr_ChainExceptions() -- because _PyErr_SetObject() does the cycle detection we've been discussing, and _PyErr_ChainExceptions() doesn't. While _PyErr_SetObject()'s cycle detection isn't complete in that it can't detect cycles that begin further down the chain, it's good enough for this case. ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue40696> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
