Shawn Heisey created SOLR-7659:
----------------------------------
Summary: 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
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.
