I tried to run the auto upgrade to the latest version. Worked on
Windows/Rocket several times. Would not work on my linode vps because of
various permissions problems. Not a big deal.
Uploaded and unzipped the zip file in /var/web2py. Set permissions so
that www-data is the group for all files with rw access.
My constant result is uWSGI Error Python Application not found. Prior to
the update, this had never occurred. In the update, I did not modify my
uWSGI config at all.
Here is the uWSGI log:

You can see in the log that the import of gluon.main fails. I tried a very
old hint from Massimo to hard code the path to web2py in wsgihandler.py.
This is what lines of wsgihandler.py up to that point look like:

In httpd.conf put something like:

# change these parameters as required
LOGGING = False
SOFTCRON = False
import sys
import os
path = '/var/web2py'
os.chdir(path)
sys.path = [path] + [p for p in sys.path if not p == path]
sys.stdout = sys.stderr
import gluon.main
if LOGGING:
application = gluon.main.appfactory(wsgiapp=gluon.main.wsgibase,
logfilename='httpserver.log',
profilerfilename=None)
else:
application = gluon.main.wsgibase
if SOFTCRON:
from gluon.settings import global_settings
global_settings.web2py_crontype = 'soft'
I also set the sys.path for python to include both web2py and web2py/gluon
in my uwsgi init script: PYTHONPATH=/var/web2py:/var/web2py/gluon. After
doing this the uwsgi log reports added /var/web2py:/varweb2py/gluon to
pythonpath. This resulted in a different import error--now it can't find
wsgihandler ("ImportError: No module named wsgihandler").
This is very frustrating. Everything worked perfectly with earlier version
of web2py. Config is just massively fragile with so many moving parts.
Sorry for the long post. Thanks for your help.
