> If you give invalid hostname to zookeeper_init method, it's not able to
> resolve it, and it tries to do the cleanup (free buffer/completion lists/etc)
> . The adaptor_init() is not called for this code path, so the lock,cond
> variables (for adaptor, completion lists) are not initialized.
> As part of the cleanup it's trying to clean up some buffers and acquires
> locks and unlocks (where the locks have not yet been initialized, so
> unlocking fails)
> lock_completion_list(&zh->sent_requests); - pthread_mutex/cond not
> initialized
> tmp_list = zh->sent_requests;
> zh->sent_requests.head = 0;
> zh->sent_requests.last = 0;
> unlock_completion_list(&zh->sent_requests); trying to broadcast here
> on uninitialized cond
> It should do error checking to see if locking succeeds before unlocking it.
> If Locking fails, then appropriate error handling has to be done.
