Bug 35036 – Introduce InspectorFrontendClient that would provide InspectorFrontend with an interface to the embedder

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

[Yury Semikhatsky]

Currently there is a bunch of methods in InspectorController that are called from InspctorFrontend to modify its window(such as moveWindowBy, showWindow, attachWindow etc.). Most of them are delegated to the InspectorClient. This design assumes that the frontend lives in the same process as the inspectorcontroller of the inspected page. To support out-of-process frontend we need to break this dependency.

Currently InspectorFrontendHost depends on InspectorClient, InspectorController and InspectorFrontend. The proposal is to introduce InspectorFrontendClient which would provide the frontend with an interface to the underlying platform. Some of its functionality is currently a part of InspectorClient and should be removed from there.

InspectorController-->o--IncpetctorClient
  |
  +-->o--InspectorFrontend-->o--(inspector UI(*.js))-->o--InspectorFrontendHost-->o---InspectorFrontendClient
                        |
  InspectorBackend--o<--+

All the messages from InspectorController to the frontend should go through InspectorFrontend which may be either inprocess implementation or remote frontend proxy. Frontend host should communicate with InspectorFrontendClient only and eventually all the communication with the InspectorBackend should be serialized and go through the client.

Please take a look at the patch. It works only on Mac but it should reflect general approach. I'm working on support for other platforms.
