Hi all,
I work on a TG2.3 project which has been developed using python 2.7.
Before releasing, I plan to upgrade to python 3. I'm the only user
for now so it's the best time to do so.
When setting up my environment with python3 / virtualenv and tg2.3, I
get the following error on setup :
Downloading/unpacking sprox
Running setup.py egg_info for package sprox
Traceback (most recent call last):
File "<string>", line 14, in <module>
File "/tmp/pod/tg2env/build/sprox/setup.py", line 6, in <module>
execfile(os.path.join(here, 'sprox', 'release.py'))
NameError: name 'execfile' is not defined
Complete output from command python setup.py egg_info:
Traceback (most recent call last):

NameError: name 'execfile' is not defined
----------------------------------------
Command python setup.py egg_info failed with error code 1 in
/tmp/pod/tg2env/build/sprox
According to the sprox bitbucket repository and issue tracker, -
https://bitbucket.org/percious/sprox/issue/45/add-python-3-support ,
python3 is not yet supported by sprox. I do not use sprox on my own,
so...
* Do I have some dependencies I miss ?
* Does TG2.3 really support python 3 ? (and in this case how can I
fix this sprox-specific problem ?)
Thank's.
Damien

I tried to quickstart a new project without tw dependencies and to
move my code to this new project. Now gearbox starts, but when
accessing any page, I get the following error :

repoze.who is not supporting python3 ?
Extra (last) information: the problem was because of a python2.7 user
session. I logged out with the python 2.7 instance and restart the
python 3.2 application and all went ok (ie I can start my application
port to python 3)
