30128 2009-10-06 06:55:17 -0700 [v8] fix crbug/671: XPathEvaluator.evalute() will throw "NAMESPACE_ERR: DOM Exception 14" when applied to XML with namespaces 2009-10-06 15:57:59 -0700 1 1 1 Unclassified WebKit WebCore JavaScript 528+ (Nightly build) All All RESOLVED FIXED P2 Normal --- 0 antonm webkit-unassigned ap commit-queue dglazkov eric nanto oldest_to_newest 152707 0 antonm 2009-10-06 06:55:17 -0700 This patch allows automatic conversion of functions to namespace resolvers. 152709 1 40718 antonm 2009-10-06 07:03:43 -0700 Created attachment 40718 First pass I am somewhat concerned how that complicates the logic of CodeGeneratorV8.pm. Another option I considered was to make necessary methods custom and provide hand-written implementation. However, that won't fix other methods that might have the same problem, e.g., originally I only fixed Document.createExpression, but fix propagated to XPathEvaluator.evaluate automatically. On the other hand, maybe we should decide for exceptions on case by case basis. The last thing that convinced me not to go with custom methods was Safari---they have this special logic for all XPathEvaluators. And another note. I added new layout tests into existing .html, but if it's against the rules (e.g. we'd like to emphasize that those tests verify contra standard behaviour), I'd be glad to lift them into a separate file. 152763 2 40718 dglazkov 2009-10-06 09:50:21 -0700 Comment on attachment 40718 First pass r=me. 152767 3 eric 2009-10-06 09:57:28 -0700 Does this already work in JSC? 152769 4 dglazkov 2009-10-06 09:58:09 -0700 Yep. 152772 5 40718 commit-queue 2009-10-06 10:15:30 -0700 Comment on attachment 40718 First pass Clearing flags on attachment: 40718 Committed r49191: <http://trac.webkit.org/changeset/49191> 152773 6 commit-queue 2009-10-06 10:15:33 -0700 All reviewed patches have been landed. Closing bug. 152850 7 ap 2009-10-06 13:43:21 -0700 This was already covered by fast/xpath/nsresolver-function.xhtml and many other tests. Did you see their results change when running the tests? Also, this is not a non-standard extension, see a note at the very bottom of <http://www.w3.org/TR/DOM-Level-3-XPath/ecma-script-binding.html>: "Note: The parameter resolver of the method XPathEvaluator.evaluate is specified as an object that implements the XPathNSResolver interface. ECMAScript users can also pass to this method a function which returns a String and takes a String parameter instead of the resolver parameter." 152858 8 antonm 2009-10-06 14:10:50 -0700 (In reply to comment #7) > This was already covered by fast/xpath/nsresolver-function.xhtml and many other > tests. Did you see their results change when running the tests? I didn't see any changes in LayoutTest results of both WebKit and Chromium. This nsresolver-function.xhtml apparently only tests Document.evaluate which already had necessary logic. I am aware of two cases this patch'd have fixed: Document.createExpression and XPathEvaluator.evaluate. Grepping through fast/xpath doesn't show tests for createExpression. > > Also, this is not a non-standard extension, see a note at the very bottom of > <http://www.w3.org/TR/DOM-Level-3-XPath/ecma-script-binding.html>: > > "Note: The parameter resolver of the method XPathEvaluator.evaluate is > specified as an object that implements the XPathNSResolver interface. > ECMAScript users can also pass to this method a function which returns a String > and takes a String parameter instead of the resolver parameter." Thank you very much for the pointer. I wonder maybe we should alter Document.idl then? That would make logic in codegen somewhat less involved (apparently) 152889 9 ap 2009-10-06 15:57:59 -0700 (In reply to comment #8) > This nsresolver-function.xhtml apparently only tests Document.evaluate which > already had necessary logic. I see, it's my fault then that I didn't add tests for all code paths when fixing this for JavaScriptCore. Sorry about that! > I wonder maybe we should alter > Document.idl then? That would make logic in codegen somewhat less involved > (apparently) That may have a negative effect on non-JavaScript bindings though (if only an ifdef in IDL). Hard to tell without seeing the code changes, but maybe not something worth doing at this point, when we have this implemented already. 40718 2009-10-06 07:03:43 -0700 2009-10-06 10:15:29 -0700 First
