The test session without an expiration date added in refs #22938 wasn't
always deleted on Windows because get_expiry_age() returns zero and the
file backend didn't consider that an expired session.
Introduced an AbstractBaseSession model and hooks providing the option
of overriding the model class used by the session store and the session
store class used by the model.
The session record is now only created if/when the session is modified. This
prevents a potential DoS via creation of many empty session records.
This is a security fix; disclosure to follow shortly.
Changed _session_key attribute to a property and implemented basic
validation in the setter. The session key must be 'truthy' and
at least 8 characters long. Otherwise, the value is set to None.
Changed SessionBase.pop's second argument to explicitly be default=None
rather than *args since _session is always a dict. Thanks gabor for the
report and Tim Graham for the review.
Previously, when logging out, the existing session was overwritten by a
new sessionid instead of deleting the session altogether.
This behavior added overhead by creating a new session record in
whichever backend was in use: db, cache, etc.
This extra session is unnecessary at the time since no session data is
meant to be preserved when explicitly logging out.
Thanks Curtis Malony and Florian Apolloner.
