Bug 48598

Summary:	WebScriptDebuggerDelegate: Cannot Tell if an Exception is Uncaught
Product:	WebKit	Reporter:	Joseph Pecoraro <joepeck>
Component:	WebKit API	Assignee:	Nobody <webkit-unassigned>
Status:	RESOLVED DUPLICATE
Severity:	Normal	CC:	joepeck, kelly_robinson+webkit

Version:	528+ (Nightly build)
Hardware:	PC
OS:	OS X 10.5

Description Joseph Pecoraro 2010-10-28 17:03:12 PDT

The "hasHandler" information for exceptions is lost when notifying the WebScriptDebuggerDelegate.
It may be useful for the delegate to know if the exception was uncaught or not.

The information is available, before calling the delegate, but it is ignored (note "hasHandler"):
http://trac.webkit.org/browser/trunk/WebKit/mac/WebView/WebScriptDebugger.mm#L203

Inspector uses that information to identify an "uncaught" exception:

Looks like this is being handled in:
<http://webkit.org/b/52104> Would like script debugging protocol method to differentiate between caught and uncaught exceptions
