Warn In PyThreadState_Clear() If the Thread State Still Has an Unhandled Exception #121058
Description
Feature or enhancement
Proposal:
When PyThreadState_Clear() is called, the thread state could still have an exception set. As a user, it would be helpful to know when that happens. This is similar to how we already warn the user if the thread state was still running Python code (we check tstate->current_frame).
For unhandled exceptions, I'm pretty sure we'd check tstate->exc_state (or maybe tstate->exc_info), along with tstate->current_exception. We could emit a warning, as well as print the traceback (or generally invoke sys.excepthook()).
It would probably make sense to separately warn about tstate->async_exc (and print that traceback).
Has this already been discussed elsewhere?
