Known issues and future enhancements for Saxon Debugger

[ligasgr]

• [ ] Some expressions do not get TraceExpression wrapping:
  • DocumentSorter (line 3 will never get stop at breakpoint)

    declare function local:abc() {
    let $var := <a><b><c/><d attr='e' another='value'>f</d></b><g><h>i</h></g></a>
    let $var1 := $var/b/d
    return $var1
    };
    local:abc()

  • Global variable reference (line 2 will never get stop at breakpoint)

    declare variable $var := 'a';
    $var

• [ ] Code, when run in saxon debug mode, is around 100 times slower
• [ ] Evaluation only works in expression mode (binding new variables doesn't work in SaxonExpressionEvaluator.WrappingStaticContext.bindVariable)
• [ ] Reference checking in expression evaluation window does not work (context not available)
• [ ] When stopping (after successful execution) the process exits with 137 exit code instead of 0
• [ ] Drop frame functionality
• [ ] Set value of variable
• [ ] Other breakpoint types (function call/exit, exception)
• [ ] Return list and map as element containing children instead of string representation
