149598 – ObjectPropertyConditionSet::mergedWith does not produce a minimal intersection.

Keith Miller

Reported 2015-09-28 10:42:25 PDT

ObjectPropertyConditionSet::mergeWith does not do a good job at producing a minimal merge. This can cause GetByIdVariant to believe that the there is more than one baseCondition when there in really only one.

I didn't run performance tests for this patch and I was worried that there might be a perf regression on some cases because of this. That was a false alarm. Attaching perf logs anyway for posterity.
