[jboss-jira] [JBoss JIRA] Created: (JGRP-935) NAKACK/UNICAST: replace locks with AtomicBoolean variables

NAKACK/UNICAST: replace locks with AtomicBoolean variables ---------------------------------------------------------- Key: JGRP-935 URL: https://jira.jboss.org/jira/browse/JGRP-935 Project: JGroups Issue Type: Feature Request Reporter: Bela Ban Assignee: Bela Ban Fix For: 2.8 Instead of acquiring a lock on the sender window of a message, we try to set an AtomicBoolean var in a CAS operation. Whoever succeeds in setting the var, continues to remove as many messages as possible. Everybody else returns to the thread pool. The {setting of the AtomicBoolean var and the removal} and {addition} of messages are atomic with respect to each other, ie. the NakreceiverWindow.remove() method has a lock (also to be acquired by add()) when removing a message and setting the AtomicBoolean to false if no message could be removed. MOTIVATION: we don't need AtomicBoolean vars *and* locks. Removing locks should result in a small speed improvement -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: https://jira.jboss.org/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira
