[Bug] Corese-server: Creation of blank node named graph makes queries with GRAPH impossible

MaillPierre opened this issue 8 months ago · 2 comments

Issue Description:

It is possible to create named graphs with a blank node as its name. Doing so makes any future query searching for graphs fail with an IndexOutOfBoundexception

Bug Details:
An update query that generates a new graph named after the object of a triple can generate a graph with a blank node as its name. This makes Corese-server fail any following query using the GRAPH keyword.

Steps to Reproduce:

PREFIX kgi: <http://ns.inria.fr/kg/index#>
INSERT DATA {
  kgi:test a [] 
}

PREFIX kgi: <http://ns.inria.fr/kg/index#>
INSERT {
  GRAPH ?typeGraph {
    ?typeGraph a kgi:Test
  }
} WHERE {
  ?whatever a ?typeGraph
}

SELECT * {
  GRAPH ?g {
    ?s ?p ?o
  }
}

returns no results and trigger the following error:

Expected Behavior:

Either

query n°2 should return an error,
or it should have an implicit guard that does not create blank node-named graphs
or query n°3 should not trigger an exception
