ipdb: quit does not abort

I hope I’m not the only one with this problem, but since I’ve upgraded to IPython 5, it is impossible to quit from a ipdb session, as before.

Here is a sample script:

def main():
    print('hello')
    while True:
        import ipdb; ipdb.set_trace()
        print('loop')

if __name__ == '__main__':
    main()

And a sample run:

python3 mwe.py
hello
> /home/dojeda/temp/mwe.py(5)main()
      3     while True:
      4         import ipdb; ipdb.set_trace()
----> 5         print('loop')
      6 
      7 if __name__ == '__main__':

ipdb> c
loop
> /home/dojeda/temp/mwe.py(4)main()
      2     print('hello')
      3     while True:
----> 4         import ipdb; ipdb.set_trace()
      5         print('loop')
      6 

ipdb> q
loop
> /home/dojeda/temp/mwe.py(5)main()
      3     while True:
      4         import ipdb; ipdb.set_trace()
----> 5         print('loop')
      6 
      7 if __name__ == '__main__':

ipdb> quit()
loop
> /home/dojeda/temp/mwe.py(4)main()
      2     print('hello')
      3     while True:
----> 4         import ipdb; ipdb.set_trace()
      5         print('loop')
      6 

ipdb> !!q
loop
> /home/dojeda/temp/mwe.py(5)main()
      3     while True:
      4         import ipdb; ipdb.set_trace()
----> 5         print('loop')
      6 
      7 if __name__ == '__main__':

ipdb> import sys; sys.exit(0)
*** SystemExit: 0
ipdb>

Use import os; os._exit() as a workaround

Add to ~/.pdbrc :

import os
alias kk os._exit(0)

then hit kk from inside an ipdb session, to exit.

(this is just a convenient workaround, the issue still needs to be fixed!)

How can we elevate the priority of this issue, or at least get it assigned to someone? It’s a complete show-stopper and is hurting ipdb uptake.

I believe you can close this issue as https://github.com/ipython/ipython/pull/10009 fixed the bug. I just upgraded from 5.1 to 5.3 and it is all good.

After some more investigation, it turns out that this is actually an IPython issue. A fix is in the make for IPython 5.2. https://github.com/ipython/ipython/issues/10006

Hello, I have the exact ssame issue.When I run python2 code, i cannot exit the debugger.

def main():
    print 'hello'
    while True:
        import ipdb; ipdb.set_trace()
        print('loop')

if __name__ == '__main__':
    main()

This outputs me when i try to exit:
