Uwe Schindler updated LUCENE-5612:
----------------------------------
Attachment: LUCENE-5612-more-sophisticated-crusher.patch
New server:
- Only one socket per client. The server expects the number of clients as
command line parameter.
- Once all clients were connected, its uses a McCandless' starting gun (over
network!) to fire all clients
- All clients hammer against the lock dir (for a fixed number of times) and
then close connection
- Server waits for all client threads to die (they die when client closes
connection)
Currently this server still binds to localhost only, will cleanup my code and
then it should be possible to bind to a specific IP again.
> 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)
