Description
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.
[junit4] ERROR 0.00s J1 | TestBoolean2 (suite) <<< [junit4] > Throwable #1: java.io.IOException: Could not remove the following files (in the order of attempts): [junit4] > C:\Users\jenkins\workspace\Lucene-Solr-master-Windows\lucene\build\core\test\J1\temp\lucene.search.TestBoolean2_B7B1F66EB9785AE1-001\tempDir-001: java.nio.file.AccessDeniedException: C:\Users\jenkins\workspace\Lucene-Solr-master-Windows\lucene\build\core\test\J1\temp\lucene.search.TestBoolean2_B7B1F66EB9785AE1-001\tempDir-001 [junit4] > C:\Users\jenkins\workspace\Lucene-Solr-master-Windows\lucene\build\core\test\J1\temp\lucene.search.TestBoolean2_B7B1F66EB9785AE1-001: java.nio.file.DirectoryNotEmptyException: C:\Users\jenkins\workspace\Lucene-Solr-master-Windows\lucene\build\core\test\J1\temp\lucene.search.TestBoolean2_B7B1F66EB9785AE1-001 [junit4] > at __randomizedtesting.SeedInfo.seed([B7B1F66EB9785AE1]:0) [junit4] > at org.apache.lucene.util.IOUtils.rm(IOUtils.java:329) [junit4] > at java.lang.Thread.run(Thread.java:748)
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.
