Bug 88973 – Web Inspector: [WebGL] Add minimum transport protocol from backend to frontend

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

[Andrey Adaikin]

Minimum transport protocol implementation between backend and frontend to allow capturing WebGL function calls for a given frame.
This will add:
- WebGL.captureFrame command from FE to BE
- WebGL.contextCreated & WebGL.reportFunctionCall events from BE to FE
- simple experimental implementation of the InjectedWebGLScriptSource.js

captureTraceLog ?

::traceLog (according to the WebKit guidelines). We only use get prefixes in the protocol.

traceLog

Is there a "logCaptured" event? I wonder if you should return traceLogId there instead.

traceLog

It sounds like N-1 lines from here could be extracted and reused below.

This is to capture only a single frame, i.e. we say webgl module to start capturing now *and* end capturing after the frame ends. Opposite to that, there may be startCapturing & endCapturing separate commands in the future, should we want to support capturing arbitrary number of frames.

done.

>> +                    { "name": "traceLogId", "$ref": "TraceLogId" }
>

No events for now (need a InjectedModuleHost class implementation). For now we will be poking the trace logs with getTraceLog after a time out.

>> +                "name": "getTraceLog",

did you really mean it? this is a protocol command, and as you said, we do use "get" prefixes in the protocol.

done.
