Script cleans RT sessions from DB or dir with sessions data.
Leaves in DB only one session per RT user and sessions that aren't older
than specified(see options).
Script is safe because data in the sessions is temporary and can be deleted.
Date interval in the "<NUM>[<unit>]" format. Default unit is D(ays),
H(our), M(onth) and Y(ear) are also supported.
For example: "rt-clean-sessions --older 1M" would delete all sessions that are
older than 1 month.
By default only one session per user left in the DB, so users that have
sessions on multiple computers or in different browsers will be logged out.
Use this option to avoid this.
Turn on debug output.
Functionality similar to this is implemented in
html/Elements/SetupSessionCookie ; however, that does not guarantee
that a session will be removed from disk and database soon after the
timeout expires. This script, if run from a cron job, will ensure
that the timed out sessions are actually removed from disk; the Mason
component just ensures that the old sessions are not reusable before
the cron job gets to them.
