Bug 94125 – Web Inspector: enable instrumentation of platform code

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

[Andrey Kosyakov]

Currently, we use InspectorInstrumentation as the interface that is used by inspector to instrument. This can't be used to instrument code under WebCore/platform, though, as this is deemed to be a layering violation. So let's add a lower-level instrumentation interface and implement its client within the inspector.

Minor nits, otherwise looks good.

You should remove
InspectorInstrumentation::setTimelineAgentForOrphanEvents, InspectorInstrumentation::threadSpecificTimelineAgentForOrphanEvents, etc. as well

> Source/WebCore/inspector/InspectorTimelineAgent.cpp:556
> +        m_platformInstrumentationClientSet = m_recordStack.size();

m_platformInstrumentationClientInstalledAtStackDepth

> Source/WebCore/platform/PlatformInstrumentation.h:46
> +    virtual void willDecodeImage(const WTF::String& imageType) = 0;

Here and below drop WTF::

> Source/WebCore/platform/image-decoders/png/PNGImageDecoder.cpp:265
> +    if (frame.status() != ImageFrame::FrameComplete) {

You did not remove TRACE_EVENT macro / include.
