Description:

If an urwid app is started from a shell script wrapper and is suspended with ^Z, when you try to resume the script/app with fg, the shell script wrapper is resumed, but the urwid app is still in the stopped state.

Affected versions (if applicable)

• master branch (specify commit)
• Latest stable version from pypi
• Other (specify source)

Seems to have been broken between 2.1.2 and 2.2.0

Steps to reproduce (if applicable)

$ python -m venv ~/.local/urwid
$ PATH=$HOME/.local/urwid/bin:$PATH
$ pip install urwid

$ cd examples
$ python browse.py
^Z
$ fg
... works ...

but

$ echo 'python "$@"' > runme.sh
$ sh runme.sh browse.py
^Z
$ fg
... no display ...

You can check the process state from another terminal, and the python process will be in the stopped state.

At this stage you can ^Z and fg it again, and it will get resumed the second time round.

Expected/actual outcome

fg resumes an urwid app launched from a wrapper script every time, not every other time.
