Subject [jira] [Commented] (CASSANDRA-13358) AlterViewStatement.checkAccess can throw exceptions
Date Wed, 05 Apr 2017 07:33:41 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-13358?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15956442#comment-15956442

Hao Zhong commented on CASSANDRA-13358:
---------------------------------------

I modified the code according to the Cassandra style. Although the original code has an if
check, it can avoid only NPE, not InvalidRequestException. As a result, the patch is still
necessary.

> The AlterViewStatement.checkAccess method has code lines as follow:
> {code:title=AlterViewStatement.java|borderStyle=solid}
>   if (baseTable != null)
>             state.hasColumnFamilyAccess(keyspace(), baseTable.name, Permission.ALTER);
> {code}
> These lines can throw InvalidRequestException. Indeed, DropTableStatement.checkAccess
has a similar problem, and was fixed in CASSANDRA-6687. The fixed code is as follow:
> {code:title=DropTableStatement.java|borderStyle=solid}
>  try
>         {
>             state.hasColumnFamilyAccess(keyspace(), columnFamily(), Permission.DROP);
>         }
>         catch (InvalidRequestException e)
>         {
>             if (!ifExists)
>                 throw e;
>         }
> {code}
> Please fix the problem as CASSANDRA-6687 did.
