[jira] [Reopened] (ZOOKEEPER-3253) client should not send requests
with cxid=-4, -2, or -1
[ https://issues.apache.org/jira/browse/ZOOKEEPER-3253?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Patrick Hunt reopened ZOOKEEPER-3253:
-------------------------------------
[~sjust2] - can you submit a new patch for this against 3.4 branch? I had to revert from 3.4, while it compiled fine the test was failing consistently across the 3.4 jenkins jobs. Thanks!

> Key: ZOOKEEPER-3253
> URL: https://issues.apache.org/jira/browse/ZOOKEEPER-3253
> Project: ZooKeeper
> Issue Type: Bug
> Components: java client
> Affects Versions: 3.4.9, 3.5.4, 3.6.0
> Reporter: Samuel Just
> Assignee: Samuel Just
> Priority: Minor
> Labels: pull-request-available
> Fix For: 3.6.0, 3.5.5, 3.4.15
>
> Original Estimate: 48h
> Time Spent: 4h 50m
> Remaining Estimate: 43h 10m
>
> Once the cxid value increments to -4, the client will interpret the response as an auth packet rather than as a response to a request and will transparently drop the response and the request will hang. Similarly, -2 will be seen as a ping and will be dropped hanging the request. -1 shows up as a WatcherEvent and results in the error below.
