New submission from mkocher <[email protected]>:
When using Popen with shell=True, the output of the repr is not particularly
user friendly.
When using the form `p = Popen('python --version'.split())`, the output is
reasonably output in a user friendly form of `<Popen: returncode: None args:
['python', '--version']>`.
However, when running with `shell=True`, the output is mangled.
For example, trying to run `python --help` via `p = Popen('python --version',
shell=True)` yields the following output.
`<Popen: returncode: None args: ['p', 'y', 't', 'h', 'o', 'n', ' ', '-',
'-',...>`
The original change appears to be motivated by
https://bugs.python.org/issue38724
and the PR here:
