Subject [jira] Updated: (LUCENE-2790) IndexWriter should call MP.useCompoundFile and not LogMP.getUseCompoundFile
Date Thu, 02 Dec 2010 14:00:17 GMT

     [ https://issues.apache.org/jira/browse/LUCENE-2790?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel

Shai Erera updated LUCENE-2790:
-------------------------------

    Attachment: LUCENE-2790.patch

Patch fixes the threading issue Earwin reported, by checking whether to create the CFS in
a sync block. Also, after discussing this on IRC, the code is further simplified by creating
the compound file before the new segment is committed.

However, some tests still fail on ConcurrentModException. I cannot debug it now, so am posting
the patch in case someone wants to take a stab. I can continue later. To reproduce the failure:

ant test -Dtestcase=TestIndexWriter -Dtestmethod=testDeleteUnusedFiles -Dtests.seed=-1861905402886420424:-8896948763797565454
-Dtests.codec=randomPerField
