20434 2008-08-18 14:37:37 -0700 Firefox allows "svgElement instanceof SVGTransformable" Safari does not 2014-05-12 05:23:07 -0700 1 1 1 Unclassified WebKit SVG 528+ (Nightly build) PC OS X 10.5 RESOLVED INVALID P2 Normal --- 20430 1 zecke webkit-unassigned heycam krit webmaster oldest_to_newest 88760 0 zecke 2008-08-18 14:37:37 -0700 This one is a bit tricky. There is no multiple inheritance in JavaScript and the IDL files for SVG use multiple inheritance and http://www.w3.org/TR/SVG11/ecmascript-binding.html is ambiguous. It says that that XYZElement has all functions and properties of SVGX, SVGY and SVGZ but does not say if that element is an instance of that other element. E.g. in firefox3 SVGTransformable is bound to the DOM and a "g" element is instanceof SVGTransformable. So should we add SVGTransformable and SVGLocatable to the DOM (it would probably require manual binding) to follow the SVG spec? Should we support "instanceof" as firefox3 is doing? 88761 1 22862 zecke 2008-08-18 14:39:18 -0700 Created attachment 22862 SVGTransformable test case The following test case is passed by firefox3 93772 2 eric 2008-10-02 12:47:47 -0700 If we wanted to fix this, we would fix this by making "instanceof" smarter. 93791 3 sam 2008-10-02 13:37:30 -0700 We could override instanceof for the classes in question. In fact, we probably should. 94026 4 eric 2008-10-03 19:28:43 -0700 I think this is a bug in Gecko. That's not how "instanceof" is supposed to work according to ECMAScript 262: http://bclary.com/2004/11/07/#a-11.8.6 ECMAScript seems to specify that instanceof is just supposed to walk the prototype chain (which would suggest that one might be able to manipulate said chain and change what instanceof returned. http://developer.mozilla.org/en/Core_JavaScript_1.5_Reference/Operators/Special_Operators/instanceof_Operator I think we need to file a bug against Gecko and discuss this with the SVG folks. I agree that to the web developer it might be nice to be able to ask svgElement instanceof SVGTransformable... 1008539 5 krit 2014-05-12 05:23:07 -0700 SVG2 will have a different hierarchy that we already implement. SVGTransformable is no longer part of it. 22862 2008-08-18 14:39:18 -0700 2010-06-10 20:16:25 -0700 SVGTransformable test case 0003-svg-transformable-Testcase-that-mozilla-is-passing.patch text/plain 2079 zecke RnJvbSBlMGM0Y2E3NmJjN2FmNGE1Mjg2NmJmZWUwYzhlZjg1ZjI2MjA1NWUyIE1vbiBTZXAgMTcg MDA6MDA6MDAgMjAwMQpGcm9tOiBIb2xnZXIgSGFucyBQZXRlciBGcmV5dGhlciA8emVja2VAc2Vs ZmlzaC5vcmc+CkRhdGU6IFN1biwgMTcgQXVnIDIwMDggMDE6Mzc6MzQgKzAyMDAKU3ViamVjdDog W1BBVENIXSBbc3ZnIHRyYW5zZm9ybWFibGVdIFRlc3RjYXNlIHRoYXQgbW96aWxsYSBpcyBwYXNz aW5nIGJ1dCB3ZSBhcmUgbm90CgotLS0KIC4uLi9zdmcvY3VzdG9tL1NWR1RyYW5zZm9ybWFibGUt cHJvdG90eXBlLnhodG1sICAgIHwgICAzOSArKysrKysrKysrKysrKysrKysrKwogMSBmaWxlcyBj aGFuZ2VkLCAzOSBpbnNlcnRpb25zKCspLCAwIGRlbGV0aW9ucygtKQogY3JlYXRlIG1vZGUgMTAw NjQ0IExheW91dFRlc3RzL3N2Zy9jdXN0b20vU1ZHVHJhbnNmb3JtYWJsZS1wcm90b3R5cGUueGh0 bWwKCmRpZmYgLS1naXQgYS9MYXlvdXRUZXN0cy9zdmcvY3VzdG9tL1NWR1RyYW5zZm9ybWFibGUt cHJvdG90eXBlLnhodG1sIGIvTGF5b3V0VGVzdHMvc3ZnL2N1c3RvbS9TVkdUcmFuc2Zvcm1hYmxl LXByb3RvdHlwZS54aHRtbApuZXcgZmlsZSBtb2RlIDEwMDY0NAppbmRleCAwMDAwMDAwLi5hYjAw YmEwCi0tLSAvZGV2L251bGwKKysrIGIvTGF5b3V0VGVzdHMvc3ZnL2N1c3RvbS9TVkdUcmFuc2Zv cm1hYmxlLXByb3RvdHlwZS54aHRtbApAQCAtMCwwICsxLDM5IEBACis8aHRtbCB4bWxucz0iaHR0 cDovL3d3dy53My5vcmcvMTk5OS94aHRtbCI+Cis8aGVhZD4KKzxzY3JpcHQgc3JjPSIuLi8uLi9m YXN0L2pzL3Jlc291cmNlcy9qcy10ZXN0LXByZS5qcyI+PC9zY3JpcHQ+Cis8L2hlYWQ+Cis8Ym9k eT4KKzxwIGlkPSJkZXNjcmlwdGlvbiI+PC9wPgorPGRpdiBpZD0iY29uc29sZSI+PC9kaXY+Cis8 c2NyaXB0PgorPCFbQ0RBVEFbCitkZXNjcmlwdGlvbigiVGVzdCB0aGF0IGFsbCB0cmFuc2Zvcm1h YmxlIGVsZW1lbnRzIGFyZSBpbnN0YW5jZSBvZiBTVkdUcmFuc2Zvcm1hYmxlIik7CisKKy8vIENo ZWNrIGlmIGl0IGlzIHByZXNlbnQKK3Nob3VsZEJlVHJ1ZSgiU1ZHVHJhbnNmb3JtYWJsZSAhPSB1 bmRlZmluZWQiKTsKK3Nob3VsZEJlVHJ1ZSgiU1ZHTG9jYXRhYmxlICE9IHVuZGVmaW5lZCIpOwor c2hvdWxkQmVUcnVlKCJFdmVudFRhcmdldCAhPSB1bmRlZmluZWQiKTsKK3Nob3VsZEJlVHJ1ZSgi U1ZHU3R5bGFibGUgIT0gdW5kZWZpbmVkIik7CisKK3Nob3VsZFRocm93KCJuZXcgU1ZHVHJhbnNm b3JtYWJsZSgpIik7CisKKy8vIENoZWNrIGV2ZXJ5IHRyYW5zZm9ybWFibGUgZWxlbWVudAordmFy IGVsZW1lbnRzID0gWyJnIiwgImRlZnMiLCAidXNlIiwgImltYWdlIiwgInN3aXRjaCIsICJwYXRo IiwgInJlY3QiLCAiY2lyY2xlIiwKKyAgICAgICAgICAgICAgICAiZWxsaXBzZSIsICJsaW5lIiwg InBvbHlsaW5lIiwgInBvbHlnb24iLCAidGV4dCIsICJjbGlwUGF0aCIsCisgICAgICAgICAgICAg ICAgImEiLCAiZm9yZWlnbk9iamVjdCIsIF07Citmb3IgKGkgPSAwOyBpIDwgZWxlbWVudHMubGVu Z3RoOyArK2kpIHsKKyAgICBkZWJ1ZygiUnVubmluZyB0ZXN0IGZvciAiICsgZWxlbWVudHNbaV0p OworICAgIHZhciBkYXRhID0gZG9jdW1lbnQuY3JlYXRlRWxlbWVudE5TKCJodHRwOi8vd3d3Lncz Lm9yZy8yMDAwL3N2ZyIsIGVsZW1lbnRzW2ldKTsKKyAgICBzaG91bGRCZVRydWUoImRhdGEgIT0g dW5kZWZpbmVkIik7CisgICAgc2hvdWxkQmVUcnVlKCJkYXRhIGluc3RhbmNlb2YgU1ZHVHJhbnNm b3JtYWJsZSIpOworICAgIHNob3VsZEJlVHJ1ZSgiZGF0YSBpbnN0YW5jZW9mIFNWR0xvY2F0YWJs ZSIpOworICAgIHNob3VsZEJlVHJ1ZSgiZGF0YSBpbnN0YW5jZW9mIEV2ZW50VGFyZ2V0Iik7Cisg ICAgc2hvdWxkQmVUcnVlKCJkYXRhIGluc3RhbmNlb2YgU1ZHU3R5bGFibGUiKTsKK30gCisKK3Zh ciBzdWNjZXNzZnVsbHlQYXJzZWQgPSB0cnVlOworXV0+Cis8L3NjcmlwdD4KKzxzY3JpcHQgc3Jj PSIuLi8uLi9mYXN0L2pzL3Jlc291cmNlcy9qcy10ZXN0LXBvc3QuanMiPjwvc2NyaXB0PgorPC9i b2R5PgorPC9odG1sPgotLSAKMS41LjQuMwoK
