When a session expires close any event streams that have been opened
with that session. This prevents an attacker with a leaked session
cookie from opening a stream and receiving updates indefinitely without
being detected.
By sending the session the event stream is opened with when the stream
is established this closure on session expiry also serves as a way for
a user agent to be notified whenever its own access level changes.
In order to minimise the window of opportunity to steal a session,
automatically rotate it onto a new session on a frequent basis. This
makes a session cookie older than the automatic rollover time less
likely to grant access and more likely to be detected.
Should a stolen session cookie get rotated while the attacker is using
it, the user will be notificed that their session has been taken the
next time they open the app if the user re-visits the website before the
session is discarded.
I firmly believe in free software.
The application I'm making here have capabilities that I've not seen in
any system. It presents itself as an opportunity to collaborate on a
tool that serves the people rather than corporations. Whose incentives
are to help people rather, not make the most money. And whose terms
ensure that these freedoms and incentives cannot be taken back or
subverted.
I license this software under the AGPL.
Rename the base Entity type to ApiEntity, and the base EntityToombstone
to ApiTombstone to better reflect the reality that its only used in the
API interface and that the client and server types uses its own base if
any.
Remove EntityLiving and pull EntityTombstone out of of the base entity
type so that the types based on ApiEntity are always living entities and
if it's possible for it to contain tombstone this will be explicitly
told with the type including a union with ApiTombstone.
Refactor the types of the ClientEntity and ClientMap to better reflect
the types of the entities it stores and converts to/from.
