[jira] Updated: (SLING-339) Implement job acknowledge

["Carsten Ziegeler (JIRA)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/SLING-339?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Carsten Ziegeler updated SLING-339:
-----------------------------------

             Priority: Blocker  (was: Major)
    Affects Version/s: Extensions Event 2.0.2
        Fix Version/s: Extensions Event 2.0.4
             Assignee: Carsten Ziegeler

Especially, if jobs can't be run in parallel, the first job without a processor stops further processing of these jobs as the finishedJob() method is never called.
This can especially happen on startup, when the event listeners haven't been registered yet.

> Currently there is no acknowledge that someone is interested in processing a job. This results in the problem
> that jobs might end up locked in the repository for ever if there is noone interested in processing this kind of
> job.
> This couldbe solved by requiring that a job processor acknowledges the receival of a job and thereby indicates that it will process this job. This could also be used to deny other processors for this job.
> If a job is not acknowledged during a specified timeout, the job will be removed.
