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
