Bug 112844 – [CSS Shaders] Remove the cache of validated programs

• Component: Layout and Rendering
• Status: RESOLVED FIXED

[Alexandru Chiculita]

Once 112602 is fixed we could remove the redundant cache of the validated programs. We could also remove the ValidatedCustomFilterOperation as we can reference the CustomFilterValidatedProgram directly from the CustomFilterProgram.

Looking forward to this! It should simplify things.

Posting a patch for Alex's informal review. Also, Qt EWS probably won't like this patch.

This change seems to require a test file.

Remove the typedef from this file.

Remove the CustomFilterValidatedProgram from this file.

> Source/WebCore/platform/graphics/filters/CustomFilterProgram.h:66

Move this to the .cpp file to avoid brining CustomFilterValidatedProgram in the header.

Eventually we should move this out of CustomFilterProgramInfo.h.

This looks like it could have been a different patch.

Let's extract the validation out of CustomFilterValidatedProgram into a separate class like CustomFilterValidator where we could store the mix/webgl shader validators and have all the blending code.

CustomFilterValidatedProgram should only contain the "storing" logic, it is just the result of the CustomFilterValidator. I think we could consolidate that with CustomFilterProgram (which is the 'raw' program information).

Thanks for the review, Alex!

I'll split this patch up into smaller, incremental refactors:
Bug 114640
Bug 114637
bug 114639
Bug 102529 (already existed)

And a bug to add a test:
Bug 114636

Yes, I won't do this change here. I've filed bug 114636 to cover it.

Yes, turns out we have bug 102529 for this.

I agree. Filed bug 114639.

Unlike the last patch, this patch doesn't try to refactor everything :). It just removes the mesh cache.

*the validated program cache I mean. (I'm thinking about too many caches..)

m_globalContext is now a weakReference to the Global Context that could be deleted before this object. Not sure how that could happen, but it would be better to remove the need for this reference.

In this patch, I've removed the weak reference to CustomFilterGlobalContext in CustomFilterValidatedProgram.

Looks good, just one small nit.

You could use compiledProgram.release() in here.

In this patch, used compiledProgram.release() like Alex suggested.
