Comment #4 on issue 17356 by aialexiskander: Support displayName to name
anonymous functions in Developer Tools
http://code.google.com/p/chromium/issues/detail?id=17356
The name inferring does not always work well—especially for constructors,
which are
important for the heap profiler. displayName should be guaranteed to work.
For instance, what if I do this:
var someObject = My.Class.extend({
mySubObjectType: My.Class.extend({ some: settings }),
init: function(){ this.mySubObject = My.Class.create(); }
})
// my.class.create:
create: function(){
var C = this;
return new C(arguments); // it does use a function that could have its
displayName
set
}
SproutCore works something like this. While each class _does_ have its own
function,
Chrome and v8 are unable to determine their names, so they all come up under
SC.Object or something similar in the heap profiler, making that profiler
entirely
useless.
