Bug 102833 – [EFL][WK2] 3D pixel tests are failing

• Component: Tools / Tests
• Status: RESOLVED WONTFIX

[Yael]

In the current setup, we dump pixel results from the web process, bypassing the Texture Mapper. In order to correctly dump the pixels for 3D transforms we have to do the painting in the UI process, the same as was done for Qt.
A patch is coming.

Patch

Generate a snapshot of the view in the UI process instead of the web process.
We have to use Texture Mapper in order to correctly paint 3D transforms etc.

Since I could not find an efl based API that will give me a snapshot, and I cannot use both evas and openGl API in the same file, I created a new file, in which I use openGL to get a snapshot.

yes. both '{' and '}' are inside #if USE(ACCELERATED_COMPOSITING)

Unfortunately this will not work for opengl ES.
For GL ES2 it will be GLES2/gl2.h, for GL ES1 it will be  GLES/gl.h

I think there should be single place for this, may be OpenGLShims.h ?

I got a tip from Carsten Haitzler on the enlightement mailing list about some ecore_x API that I can use. I will give that a try first.

Address comment #2 and comment #4.
XShmGetImage is failing to grab the image, so I resorted to glReadPixels, which is what the Qt port does.

I did not understand why we converted to a cairo surface and then back to a WKImageRef. Why not return WKViewGetSnapshot(toAPI(m_view)) directly?

Can you please tell me which coding guideline says this?

I didn't know if it is ok to return a cairo type in our API. If that is ok, then there is no need for the multiple conversions.

It is not documented in the WebKit style guidelines document but Benjamin Poulain commented about this about on one of my patches:
https://bugs.webkit.org/show_bug.cgi?id=101257#c22

I also landed a cleanup patch regarding this in:
https://bugs.webkit.org/show_bug.cgi?id=101859

While this makes no difference for primitive types, it usually does for complex types. Therefore, it is good practice to use prefix operator whenever possible.

What I mean is WKViewGetSnapshot() returns a WKImageRef and this function returns a WKImageRef. Why not return the output of WKViewGetSnapshot() directly? Instead you are creating a surface using WKImageCreateCairoSurface() from the WKImage, then converting the surface back to a WKImage. I did not understand the reason for this.

TestInvocationEfl.cpp is almost a copy of TestInvocationCairo.cpp, with some modifications specific to EFL.
I was hoping to get some comments regarding if people prefer that the file is split, or to add the EFL specific bits to TestInvocationCairo.cpp.
I think your comments are result of copy/pasted code from TestInvocationCairo.cpp.

[Chris Dumez]

Adding a few GTK guys to see if they have an opinion regarding the addition of EFL specific code in TestInvocationCairo.cpp (https://bugs.webkit.org/show_bug.cgi?id=102833#c15).

Wrong alphabetical order.

> +        return WKImageCreateFromCairoSurface(surface.get(), 0);

If you don't use local variable, I think you can remove "{", "}" in this function.
return WKImageCreateFromCairoSurface(createSurfaceForImage(sd->image).get(), 0);

Or, because you define *surface* variable two places, I think you can declare it first on 1022 line.

> Source/WebKit2/UIProcess/API/efl/EwkViewImpl.cpp:1030

I prefer to use full name. e.g) naviveSurface.

IMO, it would be better if you move this macro to above #if USE(OPENGL_ES_2)

There seems to be quite a bit of duplication with TestInvocationCairo.cpp. I really wish we could avoid that.

Personally, I would add #ifdefs in TestInvocationCairo.cpp to git EFL port's need. This would avoid the duplication.
Any other opinion on this?

Unfortunately, many of the failures are real failures.
I was looking today e.g. the css/sticky results and the actual results match what I see in MiniBrowser. Which means we have bugs that need to be fixed.

Thanks to kbalazs, who helped me analyze some of the flaky tests. It seems that we have a bug in the way we draw the scrollbars. If you look at the expected results images, they are completely wrong in many tests. I will file a separate bug about that.

Many tests don't seem that way. As an example (and this one seems common) fast/forms/input-first-letter-edit.html is just empty (totally white) when it fails. If you look at the test, it is highly unlikely to be a real failure: it's basically just

<body>
    <input type="text" id="target" />
</body>

with a bit of script that 'types' text into the input. I don't think that really renders as an empty page.
