Created attachment 94624 [details] Patch First patch for comments an discussions, not for landing. I need to add tests before I upload a patch for review.

Or is it too much work, to move from from the current approach? No. This doesn't work right now. At this point the animator was not created and we can't move this operation to SVGAnimatedTypeAnimator.

I described it in the ChangeLog. Take this example: values=" 3px ; 4px;5px" This would be splitted into the following strings: " 3px", " 4px" and "5px". For SVGLength just the last value is correct. So we have to delete all whitespaces before and after the value. This was done in SVGAnimateElement for every value in the past. Even for "from", "to" and "by". But that is incorrect. If we have from=" 4px", the parser should treat this as a failure, like we do it for x=" 4px". > > > LayoutTests/svg/animations/script-tests/svglength-animation-LengthModeWidth.js:37 > > + shouldBeCloseEnough("rect.width.baseVal.value", "200", 0.01); > > I'd remove the baseVal checks from all tests, only check the animVal, otherwhise they are wrong as soon as we implement animVal support for real. Correct. Thats why I'd leave them in. This way we have of course to change a lot of tests once we differ between them, but we will have a lot of tests that make sure that they are set correctly. Btw. we do it that way on all animation tests.

Can be an inline function, yes. But ensureAnimator would still need the argument m_animatedAttributeType, otherwise we would call determineAnimatedAttributeType twice. The first time to get the correct animation typ, the second time for the animator.

The animator may does not exist. Have to check if all necessary values exist. Investigate in this.

It is not possible that we fail here. The string is generated from the computedValue of an existing CSS property (for supporting inheritance). so we can assert here. >> Source/WebCore/svg/SVGLength.h:91 >> + void setValueAsString(const String&, SVGLengthMode); > > Hm, for consistency - pass on the Ec? Would not be interesting for our needs. I wouldn't pass an EC. See comment above. It's just used to get a SVGLength from a computed CSS property value.

I still understand the ChangeLog, also it's not using proper english. "rewrite the parsing code for parsing the values"?? I also don't know whether we're supporting anims between different units now with your patch or not. Please post a new ChangeLog at least... > Source/WebCore/svg/SVGAnimateElement.cpp:453 > + ensureAnimator(m_animatedAttributeType)->calculateFromAndByValues(m_fromType, m_toType, fromString, byString); Why does everyone have to pass m_animatedAttirbuteType??

I'd remove this and rather provide an unimplemented private constructor, so no-one can ever create an object of type SVGAnimatorFactory.

Comment on attachment 96927 [details] Patch View in context: https://bugs.webkit.org/attachment.cgi?id=96927&action=review Great patch, r=me with some final comments: > Source/WebCore/ChangeLog:8 > + For SMIL animations of attributes or CSS properties in SVG we have a lot of transformations of the values. At first the target element When running SMIL animations within SVG, we unnecessarily transform the underlying SVG primitive datatype to strings, number+units, and back. s/At first/As first step/ > Source/WebCore/ChangeLog:10 > + seperate it into a number and its unit. In the further steps we just animate the number. This number gets transformed back to a string s/separate/split/ > Source/WebCore/ChangeLog:16 > + This patch does not attend to the string transformations, but addresses the parsing of the string back to a number and unit in the s/attend/attempt to change/? This is invalid english :( > Source/WebCore/ChangeLog:19 > + SVG animation code. We shouldn't add an own parser to SVGAnimateElement but should use the responsible parsers of the SVG primitive datatypes. > + Also the current parser of SVGAnimateElement does not handle most unit types, nor is it possible to animate lists like SVGLengthList with the > + parsed content. An animation of values with different unit types is not possible: We shoulnd't add an own parser to??? There's no need to write a new parser in SVGAnimateElement to parse SVG primitive datatypes, we can instead reuse the existing ones. > Source/WebCore/ChangeLog:25 > + For the example above we would animate the rect width from 20px to 10px in 4 seconds and jump to the 10% of the view port at the end of the s/view port/viewport/ > Source/WebCore/ChangeLog:39 > + With this patch I add the AnimatorFactory and convert SVGLength animation to the new concept.
