Doesn't that potentially break currently working applications? And while having tests is great, I'm not sure I agree with the premise that it's better to return E_NOTIMPL than to forward to an implementation that may have subtle differences but probably doesn't in most cases.

This may have come up before, but any reason you can't call d3drm_frame3_QueryInterface() directly here?

I don't disagree with you. I just want an acceptable patch for this as I'll need it for implementing viewports. Also a lot of version 2 stuff uses version 1 frames as well, which makes it more important. I've CC'd Stefan in this mail, hopefully we can agree on something which works for all.

I could probably put these stubs after version 3, but wouldn't that make the version order in the file 2->3->1? Maybe a separate patch could rearrange it to 3->2->1. Maybe we could do that after these stubs are added.

I'd make the order
d3drm_frame3_QueryInterface() d3drm_frame2_QueryInterface() d3drm_frame1_QueryInterface() d3drm_frame3_AddRef() d3drm_frame2_AddRef() d3drm_frame1_AddRef() etc.
I'd don't care so much if you move the version 2 functions in the same patch that introduces the version 1 functions, although I think it makes sense to do that in a separate patch.

Right, will get right on it. I'll first write a patch to rearrange it and rebase these patches on top of it. Please review the other patches in the mean time if possible. Thanks for the review!

I am fine with imperfect / possibly broken thunks. What I want to avoid is wasting too much time on possible corner cases for a thunk that thunks to an E_NOTIMPL or barely implemented function. I guess I forgot about the possibility that the existing Frame code runs any real application :-\ .
On a deeper look, it seems only GetTransform is such a thunk that doesn't have tests for version 1. I'll add this thunk and resend the patch, after the rearrangement changes.
