Uwe Schindler updated LUCENE-5612:
----------------------------------
Attachment: LUCENE-5612-tester.patch
Here is my quick tester for ant as patch. Its not yet useable for a real test
(because it never ends). We can only do this as a test, if we have some break
condition.
To run, change to lucene/core and execute "ant test-lock-factory".
The test works on Windows, although after a long time it crashes with some
Buffer problem (I think the server or client has a leak and does not close all
file descriptors of the socket, because it complains about no more connections).
On linux it fails quite quickly with a double aquired lock.
> LockStressTest fails always with NativeFSLockFactory

> I was looking at this, because i wanted to remove the static map inside
> NativeFSLockFactory (no particular reason: it just smells bad, we require
> java7, and you get overlappingexception as of java6 so its unnecessary).
> Before changing any code, i wanted to run lockstresstest first, just to
> ensure it works: but it fails always. Simple works fine always.
> Exception in thread "main" java.lang.RuntimeException:
> java.lang.RuntimeException: lock was double acquired at
> org.apache.lucene.store.VerifyingLockFactory$CheckedLock.verify(VerifyingLockFactory.java:67)
