I think Canvas2DLayerChromium should be a separate patch. You can use OwnArrayPtr<> instead of doing new[]/delete[] yourself. GLES2Canvas.cpp loadShader should use some sort of LOG macro instead of printf() to display the shader log. This function also has a new[]/delete mismatch - another good time to use OwnArrayPtr<> :). Otherwise looks great to me! 255547 3 webkit.review.bot 2010-07-23 14:03:50 -0700 Attachment 62458 did not build on chromium: Build output: http://queues.webkit.org/results/3566409 255548 4 jamesr 2010-07-23 14:07:30 -0700 The .h has its contents behind #if guards but the cpp isn't guarded. 255581 5 62467 senorblanco 2010-07-23 15:21:38 -0700 Created attachment 62467 Patch 255586 6 62468 senorblanco 2010-07-23 15:37:37 -0700 Created attachment 62468 Patch 255587 7 62468 jamesr 2010-07-23 15:47:53 -0700 Comment on attachment 62468 Patch Some nits below, but I think this looks great otherwise. > Index: WebCore/platform/graphics/chromium/GLES2Canvas.cpp > =================================================================== > --- WebCore/platform/graphics/chromium/GLES2Canvas.cpp (revision 0) > +++ WebCore/platform/graphics/chromium/GLES2Canvas.cpp (revision 0) > + > +#include "config.h" > + > +#if USE(GLES2_RENDERING) > + > +#include "GLES2Canvas.h" > + > +#include "FloatRect.h" > +#include "GLES2Context.h" > +#include "GLES2Texture.h" > +#include "OwnArrayPtr.h" #include <wtf/OwnArrayPtr.h>, otherwise I'm not sure this will compile on all systems. > +void GLES2Canvas::rotate(float angleInRadians) > +{ > + m_state->m_ctm.rotate(angleInRadians * (180.0f / 3.14159265f)); > +} Sucks to hard-code the value of pi. > Index: WebCore/platform/graphics/chromium/GLES2Canvas.h > =================================================================== > --- WebCore/platform/graphics/chromium/GLES2Canvas.h (revision 0) > +++ WebCore/platform/graphics/chromium/GLES2Canvas.h (revision 0) > +class GLES2Canvas : public Noncopyable { > +public: > + GLES2Canvas(GLES2Context* context, int width, int height); > + ~GLES2Canvas(); > + > + void fillRect(const FloatRect& rect, const Color& color, > + ColorSpace colorSpace); > + void fillRect(const FloatRect& rect); > + void clearRect(const FloatRect& rect); > + void setFillColor(const Color& color, ColorSpace colorSpace); > + void setAlpha(float alpha); > + void setCompositeOperation(CompositeOperator op); > + void translate(float x, float y); > + void rotate(float angleInRadians); > + void scale(const FloatSize& size); > + void concatCTM(const AffineTransform& affine); Leave out the parameter names in these declarations unless they are useful (i.e. 'GLES2Context* context' 'FloatRect rect' are useless, 'int width' is useful). > Index: WebCore/platform/graphics/chromium/GLES2Texture.cpp > =================================================================== > --- WebCore/platform/graphics/chromium/GLES2Texture.cpp (revision 0) > +++ WebCore/platform/graphics/chromium/GLES2Texture.cpp (revision 0) > + > +#include "OwnArrayPtr.h" #include <wtf/OwnArrayPtr.h> > +void GLES2Texture::load(void* pixels) > +{ > + glTexSubImage2D(GL_TEXTURE_2D, 0, 0, 0, m_width, m_height, glFormat, glType, buf.get()); > + } else > + glTexSubImage2D(GL_TEXTURE_2D, 0, 0, 0, m_width, m_height, glFormat, glType, pixels); > +} Indentation off here 255722 8 senorblanco 2010-07-24 09:39:11 -0700 (In reply to comment #7) > (From update of attachment 62468 [details]) > Some nits below, but I think this looks great otherwise. > > > Index: WebCore/platform/graphics/chromium/GLES2Canvas.cpp > > =================================================================== > > --- WebCore/platform/graphics/chromium/GLES2Canvas.cpp (revision 0) > > +++ WebCore/platform/graphics/chromium/GLES2Canvas.cpp (revision 0) > > + > > +#include "config.h" > > + > > +#if USE(GLES2_RENDERING) > > + > > +#include "GLES2Canvas.h" > > + > > +#include "FloatRect.h" > > +#include "GLES2Context.h" > > +#include "GLES2Texture.h" > > +#include "OwnArrayPtr.h" > > #include <wtf/OwnArrayPtr.h>, otherwise I'm not sure this will compile on all systems.

Good idea, but it doesn't seem to work (although I could be doing something wrong; see below). It seems that the compiler ignores the friend declaration during template instantiation. From looking around, it seems that other classes derived from RefCounted<> have public destructors as well. 3>d:\src\chromium1\src\third_party\WebKit\JavaScriptCore\wtf\RefCounted.h(139) : error C2248: 'WebCore::GLES2Texture::~GLES2Texture' : cannot access private member declared in class 'WebCore::GLES2Texture' 3> d:\src\chromium1\src\third_party\webkit\webcore\platform\graphics\chromium\GLES2Texture.h(58) : compiler has generated 'WebCore::GLES2Texture::~GLES2Texture' here 3> d:\src\chromium1\src\third_party\webkit\webcore\platform\graphics\chromium\GLES2Texture.h(41) : see declaration of 'WebCore::GLES2Texture' 3> d:\src\chromium1\src\third_party\WebKit\JavaScriptCore\wtf\RefCounted.h(137) : while compiling class template member function 'void WTF::RefCounted<T>::deref(void)' 3> with 3> [ 3> T=WebCore::GLES2Texture 3> ] 3> d:\src\chromium1\src\third_party\webkit\webcore\platform\graphics\chromium\GLES2Texture.h(41) : see reference to class template instantiation 'WTF::RefCounted<T>' being compiled 3> with 3> [ 3> T=WebCore::GLES2Texture 3> ] > > WebCore/platform/graphics/chromium/GLES2Texture.h:59 > + }; > nit: no semi-colon on the closing bracket of a namespace Fixed. > R=me w/ these nits fixed 256055 12 senorblanco 2010-07-26 08:44:21 -0700 Committed r64046: <http://trac.webkit.org/changeset/64046> 256081 13 fishd 2010-07-26 10:02:20 -0700 (In reply to comment #11) > Good idea, but it doesn't seem to work (although I could be doing something wrong; see below). It seems that the compiler ignores the friend declaration during template instantiation. From looking around, it seems that other classes derived from RefCounted<> have public destructors as well. Did you remember WTF:: in the friend declaration? friend class WTF::RefCounted<GLES2Texture>; We used this trick successfully elsewhere.
