Bug 37340 – Web Inspector: Fixes "wrong parent" for GCEvents that come at the end of a timeline record node.

• Component: Web Inspector (Deprecated)
• Status: RESOLVED FIXED

This patch fixes "wrong parent" for GCEvents that come at the end of a timeline record node.

The problem was as follows:

InspectorTimelineAgent::didCompleteRecord() pops the record stack and then
calls addRecordToTimeline()

addRecordToTimeline() pushes the GCEvents. This then attributes the GCEvents to
whatever is currently last on the record stack. Too bad the real parent has
already been popped :).

This means that the only time GCEvents are correctly parented are when they
happen to get pushed by some other peer node closing BEFORE their parent tries
to pop.

The solution:

Add a call to pushGCEventRecords() to didCompleteCurrentRecord(). Simply remove the call to pushGCEventRecords() from addRecordToTimeline() and just ensure that callers of addRecordToTimeline() push the GCEvents if they need to.
