[jira] [Updated] (ZOOKEEPER-2804) Node creation fails with NPE if
ACLs are null
[ https://issues.apache.org/jira/browse/ZOOKEEPER-2804?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Bhupendra Kumar Jain updated ZOOKEEPER-2804:
--------------------------------------------
Description:
If null ACLs are passed then zk node creation or set ACL fails with NPE
{code}
java.lang.NullPointerException
at org.apache.zookeeper.server.PrepRequestProcessor.removeDuplicates(PrepRequestProcessor.java:1301)
at org.apache.zookeeper.server.PrepRequestProcessor.fixupACL(PrepRequestProcessor.java:1341)
at org.apache.zookeeper.server.PrepRequestProcessor.pRequest2Txn(PrepRequestProcessor.java:519)
at org.apache.zookeeper.server.PrepRequestProcessor.pRequest(PrepRequestProcessor.java:1126)
at org.apache.zookeeper.server.PrepRequestProcessor.run(PrepRequestProcessor.java:178)
{code}
Expected to handle null in server and return proper error code to client
was:

at org.apache.zookeeper.server.PrepRequestProcessor.pRequest(PrepRequestProcessor.java:1126)
at org.apache.zookeeper.server.PrepRequestProcessor.run(PrepRequestProcessor.java:178)
{code}
Below APIs have problem.
{code}
public void create(final String path, byte data[], List<ACL> acl,
CreateMode createMode, StringCallback cb, Object ctx)
public void create(final String path, byte data[], List<ACL> acl,
CreateMode createMode, Create2Callback cb, Object ctx)
{code}
Solution:
a) Need to handle NULL ACLs in removeDuplicates method in server.
b) Also add the client side validation for null / empty ACL for above API similar to other create API
