[ http://jira.jboss.com/jira/browse/JBCACHE-1165?page=all ]
Manik Surtani resolved JBCACHE-1165.
------------------------------------
Resolution: Done
This has been fixed.
The main parts of the fix (all in the pessimistic lock interceptor) involve:
1) Each time a lock is acquired (a call to acquireLock() from within the lock() method) we
re-check whether the node we got a lock on is the same node that is in memory (checking
object identity) since another thread may have deleted the node in question, and then yet
another thread may have recreated a new node object in it's place rendering the lock
just acquired invalid.
2) Make sure removeNode calls have createIfNotExists set to true. Since lock objects
exist on the node, acquiring a lock for a remove is meaningless if the node does not
exist.

Manik Surtani commented on JBCACHE-1165:
----------------------------------------
The fix is not absolute and will require pretty bug architectural changes.
There is an edge case where a NodeNotFoundException may occur, and this is due to parent
nodes not being
write locked when children are added/removed.
The problem is in the way READ_COMMITTED is implemented, i.e., writers are not blocked by
readers and this
allows a reader to hold a lock when a writer comes in and deletes the node in question.
Workaround is to use LockParentForChildInsertRemove OR to use REPEATABLE_READ.

This sometimes manifests itself as an endless loop, and sometimes as a
NodeNotExistsException (on the putter thread) when concurrent puts and removes are
involved.

New subject: [JBoss JIRA] Reopened: (JBCACHE-1165) Endless loop in PessimisticLockInterceptor, sometimes seen as a NodeNotExistsException (when using READ_COMMITTED)
[ http://jira.jboss.com/jira/browse/JBCACHE-1165?page=all ]
Jason T. Greene reopened JBCACHE-1165:
--------------------------------------
The fix introduced another endless loop problem:
Line 441:
else
{
// do the loop again, but don't assign child_node to currentNode so that
child_node is processed again.
if (System.currentTimeMillis() > expiryTime)
{
throw new TimeoutException("Unable to acquire lock on child node
" + new Fqn(currentNode.getFqn(), childName) + " after " + timeout + "
millis.");
}
}
Since currentNode is not set to the peeked node, this code will loop until a timeout
occurs, at which point an exception is always thrown.

Resolution: Done
the solution was to reenter the loop with current node being set to its parent.
Attached tests were successfully run.
