Description Chris Lord 2022-01-13 07:27:57 PST
Currently, these two classes are doing basically the same thing when ANGLE is enabled. I think we should remove the ANGLE-specific code from NicosiaGCGLLayer and that NicosiaGCGLANGLELayer should be a sub-class of NicosiaImageBufferPipe so that they can share the code and OffscreenCanvas can benefit when we get copy-less buffer transfers for WebGL+ANGLE.

Perhaps it's coincidence, but this also seems to have fixed some flickering I was seeing prior to this patch - I don't believe this works in any significantly different way to before though, so maybe just a driver bug exposed by timing differences or something...

Great patch! Very helpful for the next refactorings.

> Source/WebCore/platform/graphics/angle/GraphicsContextGLANGLE.h:45
> -class GCGLANGLELayer;
> +class GCGLANGLEPipe;

Can we ifdef USE(ANGLE) like we do in the attribute definition?

> Source/WebCore/platform/graphics/nicosia/texmap/NicosiaGCGLANGLEPipe.h:51
> +class GCGLANGLEPipeSource;

Leftover?

I think it's convention to just declare the class regardless (at least in a previous patch where I did what you're suggesting, a review comment was to remove the #ifdef :))

Nice catch, thanks :)

This broke clean WPE builds, both clang and gcc. There's a bunch of errors, here's an extract:

Ah sorry, this is happening elsewhere in my build, something related with an empty llint offsets headers...
