Handle OSError cases where traceback frames occur from built files (#13964)...
Handle OSError cases where traceback frames occur from built files (#13964) I've been using the `_render_traceback_` method of the traceback object, provided by the `IPython.core.interactiveshell.InteractiveShell` object that you created, in the `showtraceback` method. Thanks to this, I was able to create better error messages. I appreciate it. The following issue is related to the use of this method. ```python try: # Exception classes can customise their traceback - we # use this in IPython.parallel for exceptions occurring # in the engines. This should return a list of strings. if hasattr(value, "_render_traceback_"): stb = value._render_traceback_() else: stb = self.InteractiveTB.structured_traceback( etype, value, tb, tb_offset=tb_offset ) ``` I noticed that in the recent `8.11` version, code was added to generate a traceback when the source code is too long. In this case, if the `etb.tb_frame` object is a built file or something similar, the `inspect.getsourcelines(etb.tb_frame)` method may raise an error. So I implemented a change to set the `max_len` to the minimum value and avoid the following condition when an `OSError` occurs. I think this approach can handle cases where errors occur while using the `inspect.getsourcelines()` method. If there is anything I have done wrong or any procedures I should follow, please let me know. I would greatly appreciate it if you could leave a comment and I will make the necessary changes immediately. Thank you.
