Michael Dürig commented on OAK-6520: ------------------------------------ Looking at the code it seems like the only case missing is the one where the record id determined for the base state points to a segment that does not exist. > Improve tail compactions resilience when base state cannot be determined > ------------------------------------------------------------------------ > > Key: OAK-6520 > URL: https://issues.apache.org/jira/browse/OAK-6520 > Project: Jackrabbit Oak > Issue Type: Improvement > Components: segment-tar > Reporter: Michael Dürig > Assignee: Michael Dürig > Labels: compaction, gc > Fix For: 1.8, 1.7.7 > > > This is a follow up to OAK-3349: in tail compaction the > {{FileStore.GarbageCollector.getBase()}} might fail to determine the base > state to rebase onto. In this case we should fall back to full compaction and > report (log, JMX) the problem and its exact cause. > Failing to determine the base state might be caused by a missing or invalid > {{gc.log}} file or a invalid or missing record id for the base state being > recorded in {{gc.log}}. None of these cases should impact system stability. -- This message was sent by Atlassian JIRA (v6.4.14#64029)
