Add support for Object Expiration feature
Preventing access to expired objects
------------------------------------
Re-enabled accepting X-Delete-At and X-Delete-After headers. During a GET on
an expired object, DiskFileExpired is raised by DiskFile class. This will
result in object-server returning HTTPNotFound (404) to the client.
Tracking objects to be deleted
------------------------------
Objects to be deleted are tracked using "tracker objects". These are PUT into
a special account(a volume, for now). These zero size "tracker objects" have
names that contain:
* Expiration timestamp
* Path of the actual object to be deleted
Deleting actual objects from GlusterFS volume
---------------------------------------------
The object-expirer daemon runs a pass once every X seconds. For every pass it
makes, it queries the special account for "tracker objects". Based on
(timestamp, path) present in name of "tracker objects", object-expirer then
deletes the actual object and the corresponding tracker object.
To run object-expirer forever:
swift-init object-expirer start
To run just once:
swift-object-expirer -o -v /etc/swift/object-expirer.conf
Caveat/Limitation: Object-expirer needs a separate account(volume) that
is not used by other services like gswauth. By default, this volume is
named "gsexpiring" and is configurable.
