Subject Bug with ZKWriteLock recipe
Date Fri, 30 Jan 2015 20:28:12 GMT

So there is a bug in the above code ( I think)

WARN 10:08:31,468 attempting to unlock x-93233511378059273-0000000002
DEBUG 10:08:31,468 234f44a4-7f6e-4f19-962b-fb9a7b64f6c4 released

The bug seems to be if the latch is not acquired unlock gets the from path.


Basically with two concurrent users of the lock you see this quite often.

Q.Theses lock recipes seem a bit crude...no offense... I can send a patch.
But I wonder if no one is maintaining these maybe they should be removed
(and curator recipes) suggested instead.
