Subject [jira] Commented: (LUCENE-1232) Use segments generation instead of version
Date Fri, 14 Mar 2008 17:38:24 GMT

    [ https://issues.apache.org/jira/browse/LUCENE-1232?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12578866#action_12578866

Michael McCandless commented on LUCENE-1232:
--------------------------------------------

I think this is OK: it looks like that test hit a disk full after
generation was incremented but before version was incremented, in
SegmentInfos.write.

> Right now the segments file stores generation, a long starting with 0
> that increments by 1 with each commit, and version, a long starting
> with System.currentTimeMillis() that also increments by 1 with each
> commit.
> I think they are redundant so we can replace all methods/uses of
> version with generation instead.
> Spinoff from LUCENE-1228.
