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.

Fixed TransactionManagementError in tests.
Previous commit introduced an additional check to prevent running
queries in transactions that will be rolled back, which triggered a few
failures in the tests. In practice using transaction.atomic instead of
the low-level savepoint APIs was enough to fix the problems.

Allowed nesting constraint_checks_disabled inside atomic.
Since MySQL handles transactions loosely, this isn't a problem.
commit 2a4ab1cb6e83391ff7e25d08479e230ca564bfef
Author: Aymeric Augustin <aymeric.augustin@m4x.org>

Prevented running queries in transactions that will be rolled back.
This avoids a counter-intuitive behavior in an edge case on databases
with non-atomic transaction semantics.
It prevents using savepoint_rollback() inside an atomic block without
calling set_rollback(False) first, which is backwards-incompatible in
tests.

Replaced manual savepoints by atomic blocks.
This ensures the rollback flag is handled consistently in internal APIs.
Added settings.SESSION_SERIALIZER which is the import path of a serializer
to use for sessions.
Thanks apollo13, carljm, shaib, akaariai, charettes, and dstufft for reviews.
SuspiciousOperations have been differentiated into subclasses, and
are now logged to a 'django.security.*' logger. SuspiciousOperations
that reach django.core.handlers.base.BaseHandler will now return a 400
instead of a 500.
Thanks to tiwoc for the report, and Carl Meyer and Donald Stufft
for review.
Since "unless managed" now means "if database-level autocommit",
committing or rolling back doesn't have any effect.
Restored transactional integrity in a few places that relied on
automatically-started transactions with a transitory API.
* Prevented stale session files from being loaded
* Added removal of stale session files in django-admin.py clearsessions
Thanks ej for the report, crodjer and Elvard for their inputs.
This change allows for cleaner tests: we can test the exact output.
Refs #18194: this change makes it possible to compute session expiry
dates at times other than when the session is saved.
Fixed#18458: the existence of the `modification` kwarg implies that you
must pass it to get_expiry_age/date if you call these functions outside
of a short request - response cycle (the intended use case).
* Renamed smart_unicode to smart_text (but kept the old name under
Python 2 for backwards compatibility).
* Renamed smart_str to smart_bytes.
* Re-introduced smart_str as an alias for smart_text under Python 3
and smart_bytes under Python 2 (which is backwards compatible).
Thus smart_str always returns a str objects.
* Used the new smart_str in a few places where both Python 2 and 3
want a str.
The previous commit didn't work with PyLibMC.
This solution appears to be the best compromise
at this point in the 1.4 release cycle.

Catches memcached session key errors related to overly long session keys.
This is a long-standing bug, but severity was exacerbated by the addition
of cookie-backed session storage, which generates long session values. If
an installation switched from cookie-backed session store to memcached,
users would not be able to log in because of the server error from overly
long memcached keys.
