Bug 138341 – Web Inspector: Inspector pauses 3 times when evaluating window.decodeURI('%%%')

• Status: RESOLVED
• Resolution: WORKSFORME
• Component: Web Inspector

[Joseph Pecoraro]

* SUMMARY
When pausing on exceptions is enabled, Web Inspector pauses 3 times when evaluating window.decodeURI('%%%')

* STEPS TO REPRODUCE
1. Inspect any page
2. Enable Break on All Exceptions
3. js> window.decodeURI('%%%')
  => have to continue 3 times

* NOTES
(1) is the URI Error inside of the InjectedScript's eval(...)
(2) is the call site of the eval in the InjectedScript (var result = evalFunction.call(inspectedGlobalObject, expression);)
(3) is the last statement in the finally block in the InjectedScript catching the exception.

Mark, I think this might be JSC::Debugger pausing too many times for a single exception.

Heck, just causing a ReferenceError causes 3 pauses too:

    js> asdf

This is pretty annoying.

Maybe we should auto-continue if all the call frames are just __WebInspectorInjectedScript__ or native. I think we used to have that.

Still, I am baffled by all of the pauses we are seeing.

This behaves as expected now! I think Mark's recent fixes with exceptions fixed the underlying issues here!
