What are the cache and session config variables in 0.9.6? I upgraded
my application with "paster create" and it contained:
beaker.session.key = ...
beaker.session.secret = ...
cache_dir = %(here)s/data
cache_enabled = true
cache.data = 3600
cache.static = 3600
I had defined cache.data and cache.static for my own use.
At some point I got a DeprecationWarning that all "cache_" variables
should be changed to "cache.". Looking back, it must have been
"cache_enabled" that triggered it. So I changed the underscores to
dots, and later noticed a "None" directory in my application,
containing container_lock files that looked like they belonged in the
data directory. I deleted the None directory and it came back. So i
created an empty directory with no access permissions to force an
exception, and got:

I looked in a new Pylons application and saw it still has 'cache_dir'
so I put that back, and it stopped using the None directory.
The new application's config also includes these comments:
# If you'd like to fine-tune the individual locations of the cache data dirs
# for the Cache data, or the Session saves, un-comment the desired settings
# here:
#beaker.cache.data_dir = %(here)s/data/cache
#beaker.session.data_dir = %(here)s/data/sessions
This leads me to believe these variables supercede 'cache_dir' but
they don't: 'cache_dir' is necessary whether these are set or not.
Also note that the traceback is trying to restore a session even
though the variable name is "cache_dir" and not "session_dir".
So what is one "supposed" to have in the config file for sessions and caching?
Are my cache.data and cache.static variables going to conflict with
anything in Pylons or Beaker?
