--------------------------------------
> Sync before closing file in case data loss
> ------------------------------------------
>
> Key: ARTEMIS-2414
> URL: https://issues.apache.org/jira/browse/ARTEMIS-2414
> Project: ActiveMQ Artemis
> Issue Type: Bug
> Components: Broker
> Affects Versions: 2.9.0
> Reporter: yangwei
> Priority: Major
> Fix For: 2.10.0
>
> Time Spent: 3.5h
> Remaining Estimate: 0h
>
> When we open a new page, the page sync timer might sync the current page,
> i.e. the new page and after it responses are sent back to client. And the old
> page is closed(not synced), we may lose messages if server crashes before
> dirty page cache written back into disk.
> When we switch journal file to the new file, TimedBuffer::flushBatch will be
> called in the old file. Then the file would be synced except in the case user
> sets "journalDatasync" to false. For safety we'd better sync journal file
> before closing it.
