2017-05-16Introduce CFX_UnownedPtr to detect lifetime inversion issues.Tom Sepez
There are places where an object "child" has a raw pointer back to object "owner" with the understanding that owner will always outlive child. Violating this constraint can lead to use after free, but this requires finding two paths: one that frees the objects in the wrong order, and one that uses the object after the free. The purpose of this patch is to detect the constraint violation even when the second path is not hit. We create a template that is used in place of TYPE*. It's dtor, when a memory tool is present, goes out and probes the first byte of the object to which it points. Used in "child", this allows the memory tool to prove that the "owner" is still alive at the time the child is destroyed, and hence the constraint is never violated.

Re-write to use std::vectors rather than self-managed buffers. Includes test case that breaks before patch. Formerly, we had two independent buffers whose position were tracked by the same variable, assuming that only one was being written to at a given time. This is a bad idea because it's easy to forget to zero the index when switching buffers, and start indexing into one using previously computed offsets from the other. Additionally, there were cases where the location of a partial entity wasn't discarded when switching states thus clearing the buffer tracking said entity.
