Summary: Rya Fluo Application Visibility Join Bug
Key: RYA-224
URL: https://issues.apache.org/jira/browse/RYA-224
Project: Rya
Issue Type: Bug
Affects Versions: 3.2.10
Reporter: Caleb Meier
Assignee: Caleb Meier
Fix For: 3.2.10
There is a bug in how the Rya Fluo application processes joins for BindingSet
results with visibilities. When a new BindingSet join result is processed by
the JoinObserver for a given node, it scans for results associated with the
sibling node. When the triggering BindingSet has a visibility, there is
currently a bug with how the scan prefix is formed to scan the sibling results.
The visibility is incorrectly added to the String to form the prefix, leading
to missed results in certain situations. Line 153 in JoinResultUpdater needs
to be changed to remedy this problem. In particular, the
"childBindingSetString" formed on that line needs to be split on the delimiter
"\u0001" to remove the visibility appended to that String by the
VisibilityBindingSetStringConverter.
