Dirk, would you mind setting it to 1 as well in Source/WTF/wtf/FeatureDefines.h ?

Yes of course.

I can not verify these problems. I run the tests multiple times on my mac build and all these tests passed every single time. I will watch the bots.

I cc Qt guys, maybe you can help fixing it.

Looks like a number of tests started failing after this -- presumably some interaction between the canvas path logic and regular path stuff?

Definitely. It would be interesting to know why this did not happen on the EWS bots. Both, WK1 and WK2 Qt passed.

It actually does not touch anything of the current logic for drawing paths. If it is related to this patch, I wonder if one of the new tests causes flakiness. I run the test suite multiple times with the patch applied and never got any problems. I don't know how to investigate so.

Do you have the link to the results of the failing tests?

From the last build bots result I get the following crashing tests:

  fast/canvas/canvas-currentPath.html [ Failure ]
  fast/canvas/canvas-path-constructors.html [ Failure ]
  fast/dom/constructed-objects-prototypes.html [ Failure ]

http://build.webkit.org/results/Apple%20MountainLion%20Debug%20WK1%20(Tests)/r143533%20(5686)/fast/canvas/canvas-currentPath-pretty-diff.html

From the results it looks like the attribute currentPath is not working on the bots properly. I am building from scratch again right now and investigate. The last test needs a rebaseline.

Do I miss more failing tests?

That build does not support SVG. I guarded everything but forgot one thing:

#if ENABLE(SVG)
    DOMPath(const String& pathData)
        : CanvasPathMethods()
    {
        buildPathFromString(pathData, m_path);
    }
#endif

should be

    DOMPath(const String& pathData)
        : CanvasPathMethods()
    {
#if ENABLE(SVG)
        buildPathFromString(pathData, m_path);
#else
        UNUSED_PARAM(pathData);
#endif
    }

I do not have a clean build right now. But will upload a patch ASAP.

Landed a fix for Qt and rebaselined the Ctor test.

The other two tests work absolutely fine for me. Maybe a completely clean build might fix this problem? It looks like the currentPath attribute on CanvasRenderingContext2D is not enabled on the bots.

It fails the same way here. Looks like a wrong rounding or something similar small. I would make the test as failing.
