Subject [jira] [Commented] (JCR-2859) Make open scoped locks recoverable
Date Wed, 14 Dec 2011 17:31:30 GMT

    [ https://issues.apache.org/jira/browse/JCR-2859?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13169516#comment-13169516

Julian Reschke commented on JCR-2859:
-------------------------------------

> Attached a patch. If the session is an admin session and lock is open scoped the session
will be
the lock holder so it can be unlocked. 

I think this is problematic. Consider processes running in admin sessions trying to synchronize/reserve
using locks. If all admin locks are essentially shared by all admin sessions, this will break
big time.

> The lock tokens for open scoped locks are currently tied to the session which created
the lock. If the session dies (for whatever reason) there is no way to recover the lock and
unlock the node.
> There is a theoretical way of adding the lock token to another session, but in most cases
the lock token is not available.
> Fortunately, the spec allows to relax this behaviour and I think it would make sense
to allow all sessions from the same user to unlock the node - this is still in compliance
with the spec but would make unlocked locked nodes possible in a programmatic way.
