[Mac] dropEffect is incorrect when effectAllowed = "none"

Summary [Mac] dropEffect is incorrect when effectAllowed = "none"
Daniel Bates
Reported 2009-10-05 21:41:40 PDT
The Mac build of WebKit does not comply with the HTML 5 specification for drag-and-drop with respect to the case when effectAllowed == "none" (*). Currently, the resulting drop effect in the Mac build is determined by the followings mapping when effectAllowed == "none": dropEffect: Actual drop effect: Expected drop effect: "none" -----------> "none" "none" "copy" -----------> "copy" "none" "move" -----------> "move" "none" "link" -----------> "none" "none" "dummy" -----------> "none" "none" As per section 7.9.2 of the HTML 5 specification <http://dev.w3.org/html5/spec/Overview.html#the-dragevent-and-datatransfer-interfaces>, regardless of the specified dropEffect, when effectAllowed == "none" the resulting dropEffect should be "none". (*) It also does not comply with the spec. when effectAllowed == "uninitialized", but we should resolve this in a separate bug (after fixing bug #24731) so that we can bring HTML 5 compliance to both Mac and Windows builds in a platform-independent way.

Created attachment 40685 [details] Patch No test case is included in this patch because it uses the same test case as in the patch for bug #24731.

Comment on attachment 40685 [details] Patch You should still mention which test case this fixes. If bug 24731 hasn't yet landed, you might consider landing the test with this change and skipping it on windows for now until bug 24731 can be fixed.

Before I'll land this patch, I'll add this test case to it and modify the file LayoutTest/platform/win/Skipped to skip this test.
