I've just committed a patch for the
session history support
which has been sitting in my commit queue for some
time.
The session history patch is
to support finite amount of
session
history store for a set of replicas of a
single sync content,
in order to reduce sync traffic among
them.
If a sync request belongs to an existing session
and
its cookie represents that the replica content can
be synced
by using the history store, then [add+delete] mode
of the
LDAP Content Sync protocol is used. Otherwise, [add+present]
is used unless there is no change in the context
CSN value.
Currently the session history is memory based,
hence non-persistent.
Todo items are the support of the persistent
history and the
access control to the session history.
