[jboss-jira] [JBoss JIRA] Commented: (JGRP-919) UUID.cache: timed purging of old mappings

UUID.cache: timed purging of old mappings ----------------------------------------- Key: JGRP-919 URL: https://jira.jboss.org/jira/browse/JGRP-919 Project: JGroups Issue Type: Feature Request Reporter: Bela Ban Assignee: Bela Ban Priority: Minor Fix For: 2.8 When a channel is closed, the logical name / UUID mapping is removed by calling UUID.remove(). However, if we have a View V which contains A and B, but B was closed, then V will get printed with A's logical name but B's UUID ! This is not incorrect, but doesn't look nice. A delayed purging of B's logical name/UUID mapping would allows us to still print the logical name of B instead of its UUID, even though B was closed. SOLUTION(S): - Delay every remove(): place the to be removed element into a queue, from which we purge an element E only if E is older than X milliseconds. - Alternative: remove only at JVM termination, or when cache is more than X elements big
