How to quit ipdb while in post-mortem debugging?

Question

I like to inspect error in a Python script by using:

$ python3 -m pdb my_script.py

This drops me into a pdb prompt from where I can c continue the execution, and when it hits error, I can inspect the variables and then q quit the script execution to get back to my shell.

I tried the same with iPython debugger module, since it is more colorful:

$ python3 -m ipdb my_script.py

However, I am not able to quit the debugger once I am done inspecting the error. Using the q quit command just keeps switching it between re-executing the script and post-mortem mode:

$ python3 -m ipdb my_script.py
ipdb> c
Uncaught exception. Entering post mortem debugging
Running 'cont' or 'step' will restart the program
ipdb> Inspect some variables at this point
ipdb> q
Post mortem debugger finished. The my_script.py will be restarted
ipdb> q
Uncaught exception. Entering post mortem debugging
Running 'cont' or 'step' will restart the program
ipdb> q
Post mortem debugger finished. The my_script.py will be restarted
ipdb> q
Uncaught exception. Entering post mortem debugging
Running 'cont' or 'step' will restart the program
ipdb> q
Post mortem debugger finished. The my_script.py will be restarted
ipdb> q
Uncaught exception. Entering post mortem debugging
Running 'cont' or 'step' will restart the program

As the user @ffeast commented, there is an open ipdb issue, and a few workarounds suggested. For me these worked well:

• press ctrl+z and kill %1 (or whatever the Job number is)
• execute ipdb> import os; os._exit(1)
