Re: web2py 2.0.2 possible bug

[Andrew Replogle]

I got that too in the openshift template, but because I moved the gluon dir to another location and added it to the python path with sys.path.append(). I ended up just making a symlink into web2py/ to fix that particular issue. 

Are you maintaining the standard web2py structure?

I think absolutepath is not good

Can you suggest a patch?

Why mount point is ""?

Should be fixed in trunk. Releasing 2.0.3 later today. Can you check asap?

[Massimo DiPierro]

These are all permission issues or you are running from the wrong folder.

The problem here is that gluon_parent at this point (in this install) should be /opt/web2py, and the joined path should be /opt/web2py/VERSION.

That suggests that it's being run from / and web2py is using the cwd as gluon_parent. The logic for this stuff is a little complicated, but the bottom line is that most of the handlers (look at wsgihandler.py, for example) chdir to the directory containing the handler, which is also the directory containing gluon and (usually) applications.

So unless someone is setting env.web2py_path to '/', it's hard to see how the traceback below makes sense. I can suggest some places to put prints or logging calls...

Just gessing...
But it seems that uwsgi is doing a chdir('/') (is a common practice
when daemonizing) that is affecting web2py.

[Jonathan Lundell]

The handlers chdir to os.path.dirname(os.path.abspath(__file__)). Perhaps we should use that trick in settings, instead (mutatis mutandis) to set gluon_parent directly, rather than allowing a default to cwd. Right now, settings does this:

global_settings.gluon_parent = \
os.environ.get('web2py_path', os.getcwd())

Why isn't __file__ authoritative?

global_settings.applications_parent = global_settings.gluon_parent


I'm a little wary of breaking something so fundamental, but it'd be nice to simplify matters somewhat.

I need the Spoller from uwsgi,
so in my app I have a module that imports stuff for sending Email

from gluon.tools import Mail

when I comment this line the error goes away, so I suppose that importing gluon is somewhere trying to create the /applications

Could you please try logging the cwd (os.getcwd()) just before and after that import call?
