Bug 48843 – Web Inspector: [Chromium] Profiling must survive navigation

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

[Mikhail Naganov]

From crbug/60998:

What steps will reproduce the problem?
1. Navigate to www.google.com
2. Open inspector(Ctrl+Shift+I) and go to Profile tab
3. Start profiling
4. Reload the page
5. Stop profiling

What is the expected output? 
Profile should be present

What do you see instead?
Profile is not visible

----

Also, it would be nice to resume profiling when navigation leads to a page from other domain.

Lack of tests => sadness

> WebCore/inspector/InspectorController.cpp:677
> -void InspectorController::restoreProfiler()
> +void InspectorController::restoreProfiler(bool reset)

Consider using an enum rather than a bool here to make the call sites more readable.

http://trac.webkit.org/changeset/71511 broke Qt minimal build:
../../../WebCore/inspector/InspectorController.cpp:241: error: ‘startUserInitiatedProfiling’ was not declared in this scope

Using of startUserInitiatedProfiling must be guarded 
by ENABLE(JAVASCRIPT_DEBUGGER) as its declaration.

Could you fix it?
