> Add FROM/FROM NAMED support to Fuseki
> -------------------------------------
>
> Key: JENA-162
> URL: https://issues.apache.org/jira/browse/JENA-162
> Project: Apache Jena
> Issue Type: New Feature
> Components: Fuseki
> Affects Versions: Fuseki 0.2.1
> Reporter: Rob Vesse
> Assignee: Rob Vesse
> Labels: from, from-named, sparql
> Fix For: Fuseki 0.2.1
>
> Attachments: FusekiFromSupport.patch
>
>
> Fuseki currently does not support FROM/FROM NAMED clauses returning a HTTP
> 400 error if a user tries to make use of them
> The attached patch provides for optional enabling of this feature by a user
> specified --from or --allowFrom switch when the server is started or
> programmtically via ARQ.getContext().set(Fuseki.enableFromClauses, true).
> Therefore unless a user turns this feature on by default the old behavior
> remains in place.
> When enabled Fuseki will not reject queries with FROM/FROM NAMED in them and
> will use DynamicDatasets.dynamicDataset() to build the dataset for queries,
> there is minimal overhead for queries without FROM/FROM NAMED clauses as the
> code in DynamicDatasets appears to leave the default dataset unchanged if no
> dataset description is present in the query AFAICT
> A small number of tests has been added to TestQuery.java to test the
> behaviour, more tests might be desirable and I can probably supply those if
> necessary but the ones given test all the obvious combinations with the
> trivial test data used by TestQuery
