Subject: [execnet-dev] gw python 2.4 broken, on purpose or just a bug?
Message-ID: <CAGGBzX+oXEuvZGtAxLi9PPM_UwTT2qWGE1uS=teksPf5=ULN9w@mail.gmail.com>

Commit 2df363b30a8b
use-subprocess32-if-available (pull request #13)
https://mail.python.org/pipermail/execnet-commit/2014-November/000276.html

contains:

'subprocess': ['subprocess32' if SUBPROCESS32 else 'subprocess'],

which breaks if target runs Python 2.4

I can't recall if 2.4 was abandoned, pypi used to stated 2.4-3.1, not
it states 2.6-3.x what was the latest version that supported 2.4?

Can't remember and don't have py24 isntalled.  Please just try previous
relases.

Also, there are 5 with statements in same file. So it looks like 2.5+
is really needed.
Okay I'll roll back to 1.1 and generally work on getting newer Python
everywhere.
Cheers.

Hi Prasanna,

i guess it is what is expected, yes.  It's equivalent to
not using execnet and doing "ssh HOST ; sudo " and then asking 
for os.getuid() which returns 0.

best,

Yup. I guess so. Don't know why I was so surprised.
