Bug 161656 – Web Inspector: step-into `console.log(o)` should not step through inspector javascript

• Component: Web Inspector
• Status: RESOLVED FIXED

[Joseph Pecoraro]

Summary:
step-into `console.log(o)` should not step through inspector javascript

Test:
1. <script>
2. console.log(window);
3. <script>

Steps to Reproduce:
1. Inspect test case
2. Set a breakpoint on line 2
3. Reload
  => Pauses on line 2
4. Step-in
  => Expected to step over the console.log statement, instead stayed on the line (20+ times)

Notes:
- Engineering builds can runtime toggle a debug UI to see and step through InjectedScriptSource
  - Maybe this requires a separate backend command to enable/disable this?

This seems like a special case of script black boxing.

Investigating test failures.

The issue is that SourceID could be 0, and the default HashSet doesn't allow 0. I'm making the following change to allow Map/Set with a SourceID of 0:

-    HashMap<SourceID, DebuggerParseData> m_parseDataMap;
-    HashSet<SourceID> m_blacklistedScripts;
+    HashMap<SourceID, DebuggerParseData, WTF::IntHash<SourceID>, WTF::UnsignedWithZeroKeyHashTraits<SourceID>> m_parseDataMap;
+    HashSet<SourceID, WTF::IntHash<SourceID>, WTF::UnsignedWithZeroKeyHashTraits<SourceID>> m_blacklistedScripts;

Err, this should be removed.
