[jira] [Resolved] (LUCENE-8203) Windows failures when removing test
directories
[ https://issues.apache.org/jira/browse/LUCENE-8203?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Adrien Grand resolved LUCENE-8203.
----------------------------------
Resolution: Fixed
I'm going to mark this resolved: when I look at recent builds on both the master (https://jenkins.thetaphi.de/job/Lucene-Solr-master-Windows) and 7.x (https://jenkins.thetaphi.de/job/Lucene-Solr-7.x-Windows/) branches, there are no more failing Lucene tests because of files/dirs that couldn't get removed while it was systematic before.
So it looks like Windows search was indeed the culprit. Thanks Uwe!

> I was looking at Lucene failures of Policeman Jenkins' Windows job (https://jenkins.thetaphi.de/job/Lucene-Solr-master-Windows) and they all fail when cleaning up temporary files/dirs used for testing, eg.
> {noformat}
> [junit4] ERROR 0.00s J1 | TestBoolean2 (suite) <<<

> Has anyone ideas what the problem is? At first sight it looks:
> - not due to unclosed index inputs or MockDirectoryWrapper would barf too
> - not related to the unmap hack since we have failures on tests that do not use MmapDirectory at all like TestNIOFSDirectory
> - not due to the fact that we do not release resources in a try/finally or try-with-resources block or junit would report the exception that prevented the dir/input from being closed as well
> It's also surprising how it sometimes fails with a DirectoryNotEmptyException without reporting issues about deleting inner files of the directory.
> I don't have much background on this issue so I could easily have missed something.
