Bug 32314 – [Chromium] Introduce a class for devtools message data

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

[Yury Semikhatsky]

Currently devtools message passing interface allows to send messages with exactly 3 params, class and method names. Having a class describing message payload would add more flexibility.

Reopening the bug since we need to add methods for dispatching devtools messages on the IO thread that accept WebDevToolsMessageData parameter.

It seems unfortunate that we need to mention things like "IOThread" in WebKit.  That's
an implementation detail of Chromium.  Is it possible to avoid specifying details like
this that cannot be understood without understanding Chromium?

It is named so on purpose. We need to execute these commands asynchronously wrt render thread. In our case it is IO thread that handles async dev tools agent <-> frontend communication. I do value abstraction a lot, but in this case I think we should be more transparent. It is interesting that devtools is the only feature that talks to WebKit/chromium on non-render thread. Or is there any other?
