Crash on Ctrl-Z #948
Description
Hi! Thanks for bpython, I love it's versatility and ability to make sensible suggestions and show documentation on-the-fly.
One of my use-cases is using it alternatingly with the shell (e.g. bash), and switching with Ctrl-Z (SIGSTOP) and fg (shell-builtin to foreground bpython again).
This use-case became broken at some point.
Steps to reproduce:
- Open a Terminal, e.g. xfce4-terminal 0.8.10 (shouldn't matter though), with some shell, e.g. bash 5.1.12(1)-release (shouldn't matter though)
- Start bpython (I'm using 0.22.1 with Python 3.9.9, according to bpython)
- Press Ctrl-Z (for some reason, SIGSTOP works as intended, and does not cause a crash.)
Expected behavior:
bash$ bpython
bpython Version 0.22.1 mit Python 3.9.9 /usr/bin/python3
>>>
[2]+ Angehalten bpython
[$? = 147]
bash$ jobs
[1]+ Angehalten bpython
bash$Actual behavior:
bash$ bpython
bpython Version 0.22.1 mit Python 3.9.9 /usr/bin/python3
>>> ^Z
