Re: [Bigdata-developers] update for today

[Bryan T. <br...@sy...>]

Jeremy, the 747 and 747b tests are failing in CI. Is that expected?

I fixed 737 to do with class cast exceptions, and then feeling that I would be touching similar code worked on a rather uninteresting bug 747

SELECT *
WHERE {
  BIND ( "y" as $Y ) .
  {
    BIND ( "x" as $X )
    FILTER( BOUND($Y)
# && True
# uncommenting the above line works around the bug
    )
  }
}

I made some progress, checking in three tests and a low-risk fix for one of them, but then got bogged down in what appears to be logic errors in
com.bigdata.rdf.sparql.ast.optimizers.ASTBottomUpOptimizer.handleFiltersWithVariablesNotInScope(AST2BOpContext, StaticAnalysis, QueryBase, IBindingSet[])

Unfortunately a colleague hit a more important issue late today, which I have filed as 748, and I will work on tomorrow.
I have updated the 747 ticket with the progress to date, for I fear I may not get back to it this week.

On 747, I suspect that there is a further issue which is that the work-around really should not work!
