Subject [jira] [Commented] (LUCENE-8809) Refresh and rollback concurrently can leave segment states unclosed
Date Mon, 27 May 2019 08:12:00 GMT

    [ https://issues.apache.org/jira/browse/LUCENE-8809?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16848701#comment-16848701
] 

Jan Høydahl commented on LUCENE-8809:
-------------------------------------

Branch_7_7 is also scheduled for release right after 8.1, and all commits must be planned
in the "Lucene/Solr 7.7.2" thread on dev@

[~dnhatn], please revert the branch_7_7 commit as well, I don't like to introduce new code to
branch_7_7 which has not baked successfully for several days in master.

PS: Regarding your branch_7x commit, there will not be a 7.8 release so no need to commit
to that branch.

shows that refresh and rollback concurrently can leave segment states unclosed leads to leaking
refCount of some SegmentReaders.
