I have a program running on a raspberry pi zero 2 but at a certain point it just stops, no errors, no program exit, can ctrl+c perfectly fine. It just stops doing anything and I'm not sure why.
There is a lot of complicated code that runs before this and it also calls an external library so I don't want to have to scrub through everything (that's a very deep rabbit hole). I just want to know the last line it completed before it got stuck so I can un-stuck it.
Is there any way to print the last line that was executed when it gets stuck? Maybe I can print the last line that was executed when I press ctrl+C?
So, quite a simple solution really that I apparently was not aware of. Pressing ctrl+c by default will print the traceback for the last few lines. It did not work for me because I had an exception clause that dealt with any keyboard interrupt. Getting rid of that clause forced my program to crash, now I have a separate issue of finding out what
ready, _, _ = select.select([self.fd, self.pipe_abort_read_r], [], [], timeout.time_left()) means.
But in regard to this question I guess it has been solved, thanks to AKX for clarifying.
