Shawn Heisey commented on SOLR-7659:
------------------------------------
I should know this, but I'm not sure ... since that inner class is private, do
we even need to mention implementation changes?
> DirectoryFileStream.releaseCommitPointAndExtendReserve -- should it extend
> first?

> Key: SOLR-7659
> URL: https://issues.apache.org/jira/browse/SOLR-7659
> Project: Solr
> Issue Type: Improvement
> Components: replication (java)
> Affects Versions: 5.2.1
> Reporter: Shawn Heisey
> Priority: Minor
> Fix For: 5.3, Trunk
>
> Attachments: SOLR-7659.patch

> After a misunderstanding on my part, leading to an incorrect documentation
> edit, [~shalinmangar] helped me understand how the commit reserve duration
> works.
> The resulting discussion on the dev list brought up a possible problem in
> ReplicationHandler. We wondered whether it might be possible for another
> thread to sneak in a commit point deletion in between the two statements
> found in the releaseCommitPointAndExtendReserve method on the
> DirectoryFileStream object. If it is safe to do so, I propose reversing
> those two statements so the reserve extension is done before releasing the
> commit point.
