------------------------------------
Fix Version/s: (was: 3.3.5)
3.3.6
> c interface zookeeper_close close fd too quickly.

> Key: ZOOKEEPER-1110
> URL: https://issues.apache.org/jira/browse/ZOOKEEPER-1110
> Project: ZooKeeper
> Issue Type: Bug
> Components: c client
> Affects Versions: 3.3.3
> Environment: linux platform.
> Reporter: xiliu
> Fix For: 3.3.6
>
> Original Estimate: 0.5h
> Remaining Estimate: 0.5h
>
> The correct step about close client is the client send CLOSE_OP to the
> server, wait for several seconds, the server will process the terminal
> request and close the fd.
> But the zookeeper_close interface is wrong, because the
> adaptor_send_queue(zh, 3000) (line 2332), will first wait the timeout then
> send the request.
> The right order is first send the request then wait the timeout. I change as
> follow:
> $svn diff src/c/src/zookeeper.c
