Hi,
What are "Protected Objects"?
Protected objects are objects that have no direct references from
the stack or the JavaScript heap, but must not be destroyed by the
garbage collector. Typically, they are objects that are referenced
by non-GC heap-allocated storage, like the DOM. For example, some
kinds of event listeners are protected from garbage collection.
Is there a know list of such objects? Is XMLHTTPRequest one of them?
We call protected objects "protected" because, unlike normal GC
memory, they must be explicitly reference counted in order to
protect them from premature deallocation.
This is the numbers I get
--------------------------------------------------------------
Total Objects 96,682
Global Objects 1
Protected Objects 232
Protected Object Counts by Type
1 DOMWindow
230 Function
1 JSDOMWindowShell
--------------------------------------------------------------
After a dozen clicks I get the following:
(loading json data and creating/removing DOM objects)
--------------------------------------------------------------
Total Objects 100,433
Global Objects 1
Protected Objects 358
Protected Object Counts by Type
1 DOMWindow
356 Function
1 JSDOMWindowShell
--------------------------------------------------------------
Any ideas what the Function objects could be?
