Gregory Todd Williams: RDF::Query 1.038 (original) (raw)

I’ve just uploaded a new version of RDF::Query (version 1.038). It should be available from CPAN shortly.

Notable changes since the last announced release (1.035):

• You can now pre-bind query-variables for easier querying of blank nodes.
• Updated code to support basic FILTERs in SQL compilation.
• Initial support for OPTIONALs in SQL compiler.
• Removed LWP requirement for systems without libwww.
• RDF::Query now sets error variable upon parsing error. (Access with error().)
• Fixed memory leak in RDF::Query::Stream that resulted in too many database handles.
• Fixed major SQL compilation bugs for testing equality in FILTER expressions.
• Fixed bug in SQL compilation where no WHERE clause was needed.
• Fixed bug in SQL compilation when using model-specific Statements tables.
• Fixed SPARQL parsing bug for anonymous nodes in FILTER expressions.
• Fixed DBI case-sensitivity for PostgreSQL support.
• Removed extra parens in SQL that were causing postgresql to break.

Thanks to danbri and ubu for the suggestions, patches and impetus for most of these changes.
