Stefan Egli resolved SLING-5216. -------------------------------- Resolution: Fixed considering done as more testing didn't unveil a bug at this stage. > Concurrent creation of voting can lead to continuous re-voting > -------------------------------------------------------------- > > Key: SLING-5216 > URL: https://issues.apache.org/jira/browse/SLING-5216 > Project: Sling > Issue Type: Bug > Components: Extensions > Affects Versions: Discovery Impl 1.0.2 > Reporter: Stefan Egli > Assignee: Stefan Egli > Priority: Blocker > Fix For: Discovery Impl 1.2.0 > > > This is a regression of SLING-3195: > With SLING-3195 the cluster view id was redefined from being a unique > per-voting/per view-incarnation id to being a stable, persisted, permanent > cluster Id (see [in > View.java|https://github.com/apache/sling/blob/bac2a2bf4c3ccdf6fa13866ffe6930c20b0230d6/bundles/extensions/discovery/impl/src/main/java/org/apache/sling/discovery/impl/common/View.java#L96]). > This was achieving the goal of exposing a stable view id for users of the > discovery API. > However, it introduced a regression in that this same {{getViewId()}} was > also used during voting when multiple votings happened simultaneously, to > agree on the lowest such 'view incarnation id'. With the change to making > this viewId the stable one though, and not adjusting its usage in this > multiple-votings-sorting, this sorting became broken. Basically now when > multiple votings happen simultaneously, then it can be that the participating > instances sort differently and don't agree on one vote. Resulting in the > {{HeartbeatHandler}} to come to the conclusion that there is no winner (as > there should only be 1), and start a fresh vote. Resulting in repeated new > votings being created. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
