Re: [Public WebGL] For review: ANGLE_timer_query extension
My stupid idea was that I mentioned alternative API approaches like callbacks at the beginning of this thread. I did that before really thinking trough Bens usecase. I've meanwhile thought about Bens usecase a lot, and I realized that the API proposed is pretty perfect and that I've proposed as fodder for discussion a lot of stupid things. The elegance of Bens proposal is that the API is fine grained, convenient to wrap and doesn't impose a particular way to handle timer queries onto a users application code.
I don't think that spinloops in themselves are an issue. We already have a working spinloop, it's called gl.finish. Spinlooping without a synchronization command is an issue, because that can mutate to a deadspinloop. But this is relatively easy to safeguard against and throw an exception, which I'd consider a reasonable approach to migitate the issue and educate users on how not to use the API, without changing the API flavor.
Can we stop bikeshedding on the API flavors and accept the API that ben proposed, with the provision that there is a solution to throw people out of spinlooping with a simple query counter reset since state change?
