[jira] [Updated] (SOLR-4858) updateLog + core reload + deleteByQuery = leaked directory

     [ https://issues.apache.org/jira/browse/SOLR-4858?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Hoss Man updated SOLR-4858:
---------------------------

    Attachment: SOLR-4858.patch

Patch with a test case demonstrating the problem -- this randomizes the use of hte updateLog, and 50% of the time it fails.

(haven't even begun to try and make sense of why this fails)

NOTE: test started as a patch to TestCoreContainer, hence the slightly odd layer to be testing at and the hoops needed to do the delete by query ... now that i better understand the magic 3 criteria for causing the problem, a simpler test is probably possible.

> I havene't been able to make sense of this yet, but trying to track down another bug lead me to discover that the following combination leads to problems...
> * updateLog enabled
> * do a core reload
> * do a delete by query \*:\*
> ...leave out any one of the three, and everything works fine.
