Optimize expression evaluator #1220

merged 3 commits into from Apr 29, 2019

commented Apr 25, 2019

Add only symbols referenced in the expression to the evaluator's context. This results in up to 40% less consumed time evaluating expressions on pages that have a large amount of slim symbols in their scope.

Also, catch any exception from ParseUtil, as it can trip over localized characters encoded with %'s causing it to throw runtime exceptions that don't need specific handling (if we can't parse the string as html, we treat it as a string)
