I'm having regular issues with the loading of sessions. Sometimes this
happens after restarting the webserver, sometimes in the middle of a
session.
I would see errors like;
Traceback (most recent call last):
File "/var/web/xxx/web2py-2.10/gluon/main.py", line 484, in wsgibase
session._try_store_in_cookie_or_file(request, response)
File "/var/web/xxx/web2py-2.10/gluon/globals.py", line 1167, in
_try_store_in_cookie_or_file
return self._try_store_in_file(request, response)
File "/var/web/xxx/web2py-2.10/gluon/globals.py", line 1174, in
_try_store_in_file
or self._unchanged(response)):
File "/var/web/xxx/web2py-2.10/gluon/globals.py", line 1119, in _unchanged
session_pickled = pickle.dumps(self, pickle.HIGHEST_PROTOCOL)
PicklingError: Can't pickle <type 'thread.lock'>: attribute lookup thread.lock
failed
I'm using web2py 2.10.4-stable+timestamp.2015.04.26.15.11.54 with apache
2.2.22-13+deb7u4, libapache2-mod-wsgi 3.3-4+deb7u1 on debian 7.8
I also often got errors for session.connect (gluon/main.py:437) coming from the
__getnewargs__ in storage.py because the requested attribute was not a string.
I have replaced:
__getnewargs__ = lambda self: getattr(dict,self).__getnewargs__(self)
with
def __getnewargs__(self):
if self:
try:
return getattr(dict,self).__getnewargs__(self)
except Exception as e:
logging.getLogger().error('Storage: getnewargs: got exception:
{}'.format(e))
return ()
else:
return ()
And this seems to counter that issue. I haven't found anything for the
first error though.
Any thougths?
Wim
