[jira] [Commented] (LUCENE-6770) FSDirectory ctor should use
getAbsolutePath instead of getRealPath for directory
[ https://issues.apache.org/jira/browse/LUCENE-6770?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14721093#comment-14721093 ]
Dawid Weiss commented on LUCENE-6770:
-------------------------------------
This is also an issue with Windows (if you use reparse points, so-called "junctions"). But if I recall, there was a valid reason for using this particular method.

> After upgrade from 4.1 to 5.2.1 I found that one of our test failed. Appeared the guilty was FSDirectory that converts given Path to Path.getRealPath. As result the test will fail:
> Path p = Paths.get("/var/lucene_store");
> FSDirectory d = new FSDirectory(p);
> assertEquals(p.toString(), d.getDirectory().toString());
> It because /var/lucene_store is a symlink and
> Path directory =path.getRealPath();
> resolves it to /private/var/lucene_store
> I think this is bad design decision because "direcrory" isn't just internal state but is exposed in a public interface and "getDirectory()" is widely used to initialize other components.
> It should use paths.getAbsolutePath() instead.
> build and "ant test" were successful after fix.
