[jira] [Resolved] (QPID-4735) C++ Broker ACL file size/count limit
check bug when no value declared by user
[ https://issues.apache.org/jira/browse/QPID-4735?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Chuck Rolke resolved QPID-4735.
-------------------------------
Resolution: Fixed
Fix Version/s: 0.23
Fixed at Committed revision 1466652.
Exposing the issue with the selftest function self.session.queue_declare did not work. Instead it was exposed directly with the acl.Lookup qmf functions.

> The error in the ACL code shows up when:
> 1. An ACL rule specifies an 'upper limit' rule such as filemaxsizeupperlimit
> 2. The queue_declare call from the user does not specify qpid.file_size in the queue declaration.
> The broker passes a file_size lookup value of 0 to the ACL for checking.
> The ACL code (in error) sees that the lookup value is 0 and declares the comparison a failure despite the fact that the value (0) is less than the rule's upper limit.
> The fix is not to check that a lookup value is zero but just go ahead with the comparison.
> The failure is easy to trigger in the self test.
