[jira] Commented: (LUCENE-2689) remove NativeFSLockFactory's
attempt to acquire a test lock
[ https://issues.apache.org/jira/browse/LUCENE-2689?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12918036#action_12918036 ]
Shai Erera commented on LUCENE-2689:
------------------------------------
All tests passed for me.
BTW, according to the code, this method was added due to NFS cache issues, but I agree that it's useless to call makeLock just to call obtain() some time later on. It's almost as if we should make makeLock obtain the lock right away. Is there a reason why we don't do it? Is it essential to separate it into two calls?

> NativeFSLockFactory tries to acquire a test lock the first time a lock is created. It's the only LF to do this, and, it's caused us hassle (LUCENE-2421, LUCENE-2688).
> I think we should just remove it. The caller of .makeLock will presumably immediately thereafter acquire the lock and at the point hit any exception that acquireTestLock would've hit.
