Some tests are failing on windows when they try to delete the SingleFileStore ----------------------------------------------------------------------------- Key: ISPN-12056 URL: https://issues.redhat.com/browse/ISPN-12056 Project: Infinispan Issue Type: Bug Reporter: Gustavo Lira e Silva Assignee: Gustavo Lira e Silva Priority: Major Some tests are failing on windows with the same reason, see some examples bellow: {noformat} java.lang.IllegalStateException: Cannot delete C:\j\workspace\jdg-8.0.x-jdg-func-ispn-testsuite-win-openjdk\4964bfc5\infinispan\core\target\infinispanTempFiles\ExpirationSingleFileStoreListenerFunctionalTest\0\defaultcache.dat owner=null permissions=[] {noformat} {noformat} Java.lang.IllegalStateException: Cannot delete C:\j\workspace\jdg-8.0.x-jdg-func-ispn-testsuite-win-openjdk\4964bfc5\infinispan\core\target\infinispanTempFiles\AsyncStoreWithoutEvictionFunctionalTest\cache.dat owner=null permissions=[] at org.infinispan.commons.util.Util.recursiveDelete(Util.java:1046) at org.infinispan.commons.util.Util.recursiveDelete(Util.java:1032) at org.infinispan.commons.util.Util.recursiveFileRemove(Util.java:1022) at org.infinispan.commons.util.Util.recursiveFileRemove(Util.java:1011) at org.infinispan.persistence.support.AsyncStoreWithoutEvictionFunctionalTest.clearTempDir(AsyncStoreWithoutEvictionFunctionalTest.java:39) {noformat} {noformat} java.lang.IllegalStateException: Cannot delete C:\j\workspace\jdg-8.0.x-jdg-func-ispn-testsuite-win-openjdk\4964bfc5\infinispan\core\target\infinispanTempFiles\ExpirationSingleFileStoreListenerFunctionalTest\0\defaultcache.dat owner=null permissions=[] at org.infinispan.commons.util.Util.recursiveDelete(Util.java:1046) at org.infinispan.commons.util.Util.recursiveDelete(Util.java:1032) at org.infinispan.commons.util.Util.recursiveDelete(Util.java:1032) at org.infinispan.commons.util.Util.recursiveFileRemove(Util.java:1022) at org.infinispan.commons.util.Util.recursiveFileRemove(Util.java:1011) at org.infinispan.expiration.impl.ExpirationSingleFileStoreListenerFunctionalTest.clearTempDir(ExpirationSingleFileStoreListenerFunctionalTest.java:46) {noformat} First of all we should change the old {{file.delete()}} which only return a boolean for {{Files.delete(file)}} which return an exception with a valuable information in case of the file couldn't be deleted. The real reason for the file couldn't be delete on windows is {noformat} "the file is being used by another process" {noformat} The code bellow into {{org.infinispan.commons.util.Util#recursiveDelete}} solves the problem: {noformat} Files.walk(f.toPath()) .sorted(Comparator.reverseOrder()) .map(Path::toFile) .forEach(File::delete); {noformat}
