Web Inspector: [Canvas] add getResourceInfo and getResourceState methods to the protocol

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

[Andrey Adaikin]

We need to expose replayable resource info and replay state via the protocol.
The ResourceInfo describes a replayable resource, i.e. the info about a resource that was stored to replay it later.
The ResourceState describes a current state of a resource being replayed on the back-end.

Patch to follow.

getResourceInfo (since you use output parameter).

ditto

CanvasAgent.TraceLogId

I'd introduce a small wrapper that goes into runtime cast.

@return {{id:string,...

we'll need to modify generate_protocol_externs.py to also generate JSON typedef's for @constructors, like:

/** @constructor */
CanvasAgent.TraceLog = function()
{
/** @type {CanvasAgent.TraceLogId} */ this.id;
/** @type {Array.<CanvasAgent.Call>} */ this.calls;
/** @type {number|undefined} */ this.startOffset;
/** @type {boolean|undefined} */ this.alive;
}

/** @typedef {{id:CanvasAgent.TraceLogId, calls:Array.<CanvasAgent.Call>, ...}} */
CanvasAgent.TraceLogJSON;

I'll do this in a separate patch: https://bugs.webkit.org/show_bug.cgi?id=107287
