Description noel gordon 2011-03-21 04:17:33 PDT
Following tests are not passing in dumpRenderTree --chromium.  

Comment 1 noel gordon 2011-03-21 05:01:19 PDT
Chromium currently builds against the OSX 10.5 SDK on both LEOPARD and SNOW LEOPARD, which
causes BUILDING_ON_LEOPARD to be defined via <wtf/Platform.h>.  Gradient.h defines


making the gradient paint path use the older CGShaders - CGShadingCreateRadial is used for
radial gradients, but does not support ellipsoidal gradients (this bug).

Using the newer CGContextDrawRadialGradient for radial gradients would fix the bug, but it
would also cause memory leaks for linear gradients via CGContextDrawLinearGradient on 10.5
SDK builds of the Gradient.h code (refer to changeset 54970).

Best to fix this once Chromium has real 10.6 SDK build/release system (USE_CG_SHADING will
be false) and rebaseline the layout tests to close this bug.

Alternative fix, use skia on the mac, the skai implementation know how to draws ellipsoids as required by these tests.
