Error with setup.py develop [2.2 Unstable]

[Mengu]

hi,

i have created a fresh virtual environment and did a clean install via
http://unstable.tg.gy

i created a test project with "paster quickstart -n -s -j appname" and
then i ran a "python setup.py develop". this is the output:

That is sadly a know issue in Python2.7
multiprocessing and logging don't coexist well.

It should not cause any effect as it happens at interpreter shutdown
after everything has been done.
In the case of TurboGears2 it is caused by the setup script of
tw2.forms which imports multiprocessing and logging.

You can simply ignore it or quickstart with: "paster quickstart -n -s
-j --enable-tw1 quickstore"

I'll look for a workaround with ToscaWidgets guys as soon as possible,
in the mean time it can just be ignored.

It's just an hack, but release 20120522 provides a quickstart change
that avoids the crash.
Quickstarting again the project on a virtual environment created with
that release should cause the crash anymore when doing setup.py
develop.

For people that use 2.1.5 with ToscaWidgets2 they can work around the
issue by placing at the head of their project setup.py:

try:
import logging
import multiprocessing
except:
pass

thanks alessandro.

this seems to be fixed.
