All normal paths treat null value as "remove the attribute". I think we can do without the null check, I'll just land the test case here. *** This bug has been marked as a duplicate of bug 156515 *** 1183368 6 koivisto 2016-04-13 01:38:59 -0700 Landed the test in https://trac.webkit.org/r199428 1183397 7 276270 darin 2016-04-13 08:21:00 -0700 Comment on attachment 276270 patch View in context: https://bugs.webkit.org/attachment.cgi?id=276270&action=review >> Source/WebCore/cssjit/SelectorCompiler.cpp:2823 >> + return false; > > Looks like this should be merged with the "AtomicStringImpl& valueImpl = *attribute->value().impl();" below. Checking for the null string would be more efficient than checking for the empty string for the non-null, non-empty case. So unless we want to optimize the empty string case, I suggest using isNull or checking if impl() is nullptr instead. 1183398 8 darin 2016-04-13 08:21:30 -0700 Oh, looks like we decided not to land this change and instead prevent null from ever getting here.
