<pre>Web Inspector: step-into `console.log(o)` should not step through inspector javascript
https://bugs.webkit.org/show_bug.cgi?id=161656
<rdar://problem/28181123>
Patch by Joseph Pecoraro <pecoraro@apple.com> on 2016-10-12
Reviewed by Timothy Hatcher.
Source/JavaScriptCore:
* debugger/Debugger.h:
* debugger/Debugger.cpp:
(JSC::Debugger::pauseIfNeeded):
If the Script is blacklisted skip checking if we need to pause.
(JSC::Debugger::isBlacklisted):
(JSC::Debugger::addToBlacklist):
(JSC::Debugger::clearBlacklist):
Add the ability to add a Script to a blacklist. Currently the blacklist
only prevents pausing in the Script.
* inspector/agents/InspectorDebuggerAgent.cpp:
(Inspector::isWebKitInjectedScript):
(Inspector::InspectorDebuggerAgent::didParseSource):
Always add Internal InjectedScripts to the Debugger's blacklist.
(Inspector::InspectorDebuggerAgent::clearDebuggerBreakpointState):
Clear blacklists when clearing debugger state.
LayoutTests:
* inspector/debugger/stepping/stepping-internal-scripts-expected.txt: Added.
* inspector/debugger/stepping/stepping-internal-scripts.html: Added.
Ensure step-into a console.log statement steps past it, and doesn't pause
inside the non-visible internal script.</pre>
