[jira] Updated: (ZOOKEEPER-415) zookeeper c tests hang.
Posted by "Mahadev konar (JIRA)" <ji...@apache.org>.

Mahadev konar updated ZOOKEEPER-415:
------------------------------------
Attachment: ZOOKEEPER-415.patch
it turns out that we were facing a problem with the list.get() throwing an excpetion when the list is empty, whcih would result in lock not being released and the other thread waiting on the lock and never able to acquire it leading to tests hanging. for the soln.
- added wait for events before we ever call getEvents()
- added assertion in getEvent that would fail if there are no elements available.
