I'm using file-based Beaker sessions. If something happens to the session
file, (for example, if I delete the directory on my development machine), I
get a 500 error:
File "[dir]/lib/python2.7/site-packages/beaker/session.py", line 659, in
__getattr__
return getattr(self._session(), attr)
File "[dir]/lib/python2.7/site-packages/beaker/session.py", line 655, in
_session
**params)

__init__

filedescriptor = self._open(os.O_CREAT | os.O_RDONLY)
File "[dir]/lib/python2.7/site-packages/beaker/synchronization.py", line
236, in _open
filedescriptor = os.open(self.filename, mode)
OSError: [Errno 2] No such file or directory:
'[dir]/data/sessions/lock/e/e9/e953f617010ebeee3990cce9eb345c584e5fcb96.lock'
This will be a problem in production: I'll have a standby webserver
waiting to take over in case of failure on the primary server. If the
standby were to take over, it won't have the session data and all users
with sessions will be getting 500 errors. How can I have it fail more
gracefully, and just create a new, empty session?
