[jira] [Commented] (IO-420) Detection of deleted directories fails if the directory does not exist when the observer is created.

["Joerg Pacher (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/IO-420?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13865568#comment-13865568 ] 

Joerg Pacher commented on IO-420:
---------------------------------

Issue is solved when changing FileAlterationOberserver.checkAndNotify to:

		if (rootFile.exists()) {
			rootEntry.setExists(true);
			checkAndNotify(rootEntry, rootEntry.getChildren(),
					listFiles(rootFile));
		} else if (rootEntry.isExists()) {
			rootEntry.setExists(false);
			checkAndNotify(rootEntry, rootEntry.getChildren(),
					FileUtils.EMPTY_FILE_ARRAY);
		} else {
			// Didn't exist and still doesn't
		}

> If a directory is observed, that doesn't exist when the observer is created, no deletion event will be created, when this directory is deleted again.
> Use case: mounting/unmounting of usb devices
