[jboss-jira] [JBoss JIRA] (DROOLS-997) Events that have already expired when inserted may trigger rules before expiring

[Mario Fusco (JIRA)]

     [ https://issues.jboss.org/browse/DROOLS-997?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Mario Fusco resolved DROOLS-997.
--------------------------------
    Resolution: Rejected


This is the expected behaviour since events have only to be evaluated at least once by the rule engine even if they're already expired at their insertion time.

>          Components: core engine
>    Affects Versions: 6.1.0.Final

> Events that have already expired when they are inserted have their expiration times changed to the insertion time, which will not expire until the clock ticks at least once.
> Isee the following in `drools-core/src/main/java/org/drools/core/phreak/PropagationEntry.java`:
> {code:java}
> long effectiveEnd = eventFactHandle.getEndTimestamp() + expirationOffset;
> long nextTimestamp = Math.max( insertionTime,
>                                     effectiveEnd >= 0 ? effectiveEnd : Long.MAX_VALUE );
>  if (nextTimestamp < workingMemory.getTimerService().getCurrentTime())
> {code}
> So if current time is still insertion time, the event is not expired.
