[webkit-help] Regd. Communication path from Web Inspector Front-end to WebCore

[Konrad Piascik]

The communication protocol that is used is JSON sent over WebSockets. This protocol is defined in Source/WebCore/inspector/inspector.json also there is a DerivedSource file called InspectorBackendDispatcher.cpp which is where the JSON is parsed and from which calls into the Inspector*Agent classes are made. These Agent classes can make calls to the front-end via an InspectorFrontendChannel that each WebKit port then implements.

Hope this helps,

Konrad

Subject: [webkit-help] Regd. Communication path from Web Inspector Front-end to WebCore

Hello,

I am trying to understand the communication link between Web Inspector front-end and backend. What I have observed that in the InspectorBackendStub.js file, there is a method sendMessageToBackend, which is being called to dispatch any method from WebInspector front-end to Webcore.
But the strange observation is in the InspectorBackend.sendMessageToBackend() method, it calls InspectorFronendHost.sendMessageToBackend() method, whose implementation is empty in InspectorFronendHostStub.js. It is also observed that in the WebInspector.loaded() method in inspector.js file the Websocket is not getting called.

So I am really curious to know the communication link from front-end to backend, it would be really helpful, if you  kindly give some information regarding this.

Thanks in advance.

Regards,
Deb
